Abstract

This developing study aims to provide a reliable source for understanding the industrial history of silver mining in Combe Martin, North Devon. 

Combe Martin holds the unique distinction among English parishes of having historic mines that yield both argentiferous (silver-bearing) and plumbiferous lead (pronounced "led") ores. Local mining has continued intermittently over seven centuries.

This study underscores the unusually rich silver content found in Combe Martin's extensive ore deposits. North Devon Archaeological Society has posted evidence of mining in Combe Martin dating back to at least 1135 AD.

The village sits atop substantial silver-bearing plumbiferous deposits running beneath much of its area, as illustrated in the map created by the Combe Martin Silver Mines Society. While estimates of the silver content have not been exceptional, history records that the seams (ore veins) were vast.

Combe Martin silver, extensively mined during its peak period, was once a vital source of England's precious metals. The town's rich resources played a crucial role in the nation’s economic strength and prosperity.

The decline of mining operations in Combe Martin during the late 19th century will also be discussed, including the increasing operational costs and irregular deposits of silver-lead resources that contributed to this downturn.

For a more accessible, immersive audio experience, users might consider using a screen reader for this article. 

The Combe Martin silver mines, recognised as one of England's richest deposits during the High Middle Ages and the Renaissance, significantly contributed to the Crown's revenues, funding military campaigns and economic initiatives.

These mines are documented as actively producing large quantities of silver from 1292 to 1509, during the reigns of Edward I, Edward III, Henry V, and Henry VII. This period appears to mark the peak of silver production in Combe Martin.

Through a combination of archaeological findings and scholarly sources, the article examines the technological advancements in mining practices, including the implementation of inclined drainage galleries that doubled production in the late 13th century.

We also highlight the socio-economic implications of mining activities on the local community and the broader historical context, including the impact of the English Civil War and the Industrial Revolution.

In summary, this paper emphasizes the rich industrial and mineral heritage of Combe Martin, and highlights the importance of protecting it for future generations.

Introduction

Combe Martin's silver mines were a principal national resource during the Middle Ages and Elizabethan era. And they were worked up to the late nineteenth-century. 

A great deal of important information is found in author F.J. Snell's The Blackmore Country (1911). Snell includes a description of 'Combmartin', with a lot of interesting historical detail about Combe Martin silver.

These silver mines are recorded as being "wrought, and producing immense seams" —vast quantities of ore— between 1292 and 1509 in the reigns of Edward I, Edward III, Henry V and Henry VII.

Whilst the mine at Bowhay Lane is considered Combe Martin's central mine, we must not overlook the 'West Combe Martin Mine' (West Challacombe). Run by The West Combmartin Silver Lead Mining Co. in 1877, it ultimately failed.

Today, the local Combe Martin Silver Mines Society (CMSMS), based at Bowhay Lane, continues to explore and preserve the town's mining legacy.

Historical accounts of silver mining in Combe Martin emphasised the richness of the silver deposits, and the potential for future exploitation. However, the mines were prone to flooding (Malynes, Gerard, The ancient law-merchant, 1686 [1622]). 

Water in the Combe Martin mines posed a persistent obstacle, impairing the extraction of silver-lead ore. Skilled engineers overcame the flooding problems in the 16th century, yet Royalist mining engineer Sir Thomas Bushell had limited success here during the 17th century English Civil Wars.

Despite attempts to drain the mines through inclined galleries and, later, steam engines, Combe Martin's high water table made mining less efficient, more hazardous, and potentially less profitable.

In his report first published in 1622 under the title "Consuetudo, vel Lex Mercatoria", Malynes claimed that "the silver mine in Combe Martin is said to produce 10 ounces of silver per hundredweight of ore". 

Combe Martin silver was exploited by multiple English monarchs to fund economic stimulus, royal expenditures, coin minting, and military campaigns including the Hundred Years' War.

The historian William Camden (1551-1623) wrote that the silver mines were "first discovered during the reign of Edward I, when three hundred and fifty men were brought from the Peak in Derbyshire to work here."

Scholar Thomas Fuller (1608–1661) adds to this by mentioning that "the silver was forged for Lady Eleanor, Duchess of Barr [Countess of Bar, 1269-1297, daughter of Edward I and Queen Eleanor of Castile] (Northcote, Lady R., 1908).

In 1298, the production of Devon’s silver mines doubled, due to the construction of inclined drainage galleries that facilitated the removal of water from the hillsides.

In the reign of Edward III (1327-1377) the mines yielded the King 'great profits towards carrying on the French war'. And Henry V (r.1413-1422) 'made good use of them,' but after that they were neglected for a long while.

In Queen Elizabeth's reign between 1558 and 1603, Adrian Gilbert (c.1541-1628), brother of the explorer Sir Humphrey Gilbert, began to work them again. English mining engineer Sir Bevis Bulmer (1536-1615) followed with considerable success, 'by whose mineral skill great quantity of silver was landed and refined.'

Large, continuous deposits of ore generally result in larger quantities being mined, with the potential for higher overall yields of silver, even if the silver content per specific weight of ore is not particularly high.

In summary, the evidence suggests that Combe Martin's silver mines were a historically significant resource.

Comprehensive Historical and Archaeological Insights

To provide a comprehensive account, we incorporate archaeological evidence and findings from diverse scholarly sources, including miners, historians, archaeologists, geologists, and economists.

The article highlights how the local mining operations were inextricably linked to England's broader geopolitical and military objectives over the centuries.

We have not covered the full extent and current condition of Combe Martin's underground structures. Information about the network of mine tunnels beneath the village is available from the Combe Martin Silver Mines Society.

Available evidence suggests that by the 19th century, mining in Combe Martin became capital intensive. Rising labour costs, the need for deeper mining, and expensive plant equipment contributed to this trend.

Ultimately, locating and extracting Combe Martin silver in the latter part of the 19th century became far too expensive.

For just one example, the Industrial Revolution brought a transition from traditional water and animal power to steam power. Inevitably this increased labour and machinery costs as well as fuel and maintenance costs. 

While its mining activities declined over time, Combe Martin's mineral and industrial heritage remains a key part of its history.

Combe Martin Silver Mines Society's Map of Local Mines and Adits

At the top of this page, the map of the Combe Martin Mines provides valuable insights about the historic mining activities in the area:

1. Multiple mine sites: The map shows several marked locations for mines, including the West Challacombe Mine, Old Combmartin Mine, and Knap Down Mine, indicating that there were multiple active mining sites in the vicinity.

2. Underground infrastructure: The map depicts various adits (horizontal entrances to underground mines) and shafts, suggesting an extensive network of underground mining tunnels and workings lie beneath the surface of Combe Martin.

3. Spatial distribution: The mines appear to be scattered across the landscape, with some clustered in certain areas such as Gorwell Orchard and the Old Combe Martin Mine site. Accordingly, the silver and lead deposits were dispersed rather than concentrated in a single location.

4. Topographical features: The map references natural features like streams and hills, which would have influenced the placement and accessibility of the mining sites and underground infrastructure.

5. Potential connectivity: While the map does not explicitly show interconnected tunnels, the proximity of some of the mine sites and adits suggests the possibility of a more integrated underground mining system.

6. The presence of multiple shafts, adits, and an apparent underground network suggests significant investment and effort went into developing the mining infrastructure to access and extract the ores.

7. Mining continued intermittently in the area from the Middle Ages through to the late nineteenth-century.

Associated Monuments

Devon and Dartmoor Historic Environment Record MDV12545 provides a list of associated monuments related to the Combe Martin Silver Mines. These include structures and features such as:

• Chimney, Engine House, and Forge: Key components of the mining operations.
• Various Shafts: Including but not limited to Williams' Shaft, Harris' Shaft and Vivian's Shaft, which were part of the mining infrastructure.
• Adits: Horizontal tunnels across Combe Martin, used for accessing the mines.

Combe Martin Silver Mine Powder House

Built in 1837, the Combe Martin Silver Mine Mine Powder House is a small rectangular structure made of stone rubble. It features a dry slate roof with gable ends.

The building is listed by Historic England at Group Value 2 (GVII) for its special architectural or historic interest.

List Entry Number: 1350386 | Devon and Dartmoor HER No. MDV12545

Preservation
As a listed building, the Mine Powder House represents efforts to preserve historical structures. Future generations can connect with the past, and understand the significance of these sites in England's history.

Architectural Features
Historic England describes the Powder House as a single-storey, reinforced building with an entrance at the north end. The doorway, located on the left of the north gable, has a timber lintel and a plank door.

On the west side, there is a centrally located window, also with a timber lintel, which is fitted with plank shutters.

Interior Details
Inside, the walls are lime-washed and the space is open to a reconstructed roof structure. The Mine Powder House serves as a significant example of its architectural style and historical context.

Powder House Functions
The Mine Powder House was used for the safe storage of explosives, especially gunpowder used in mining operations. As mining activities and techniques progressed in the 19th century, these buildings became essential.

The use of dynamite and other explosives became common for breaking rock and facilitating excavation. Stored on site, such propellants had to be kept away from the main mining areas.

Silver Content in Lead Galena

Lead galena, the primary ore of lead and mainly composed of lead sulphide (PbS), can contain varying amounts of silver. However, in some deposits, the silver content can be significantly higher, reaching up to 10% or more in certain geological formations.

In a publication from 1686/1622, English merchant and legal writer Gerard Malynes claimed the Combe Martin silver mines produced 10 ounces of silver per 112 pounds of ore; roughly 0.6% (The ancient law-merchant [1622]. Early English Books 1641-1700). 

On average, the silver content in lead galena ranges from about 0.1% to 1% silver by weight (Little, H.W., "Silver-Lead Relationships in British Columbia". UBC, 1940).

Hewart W. Little's foundational research is dated 1940, yet its principles and methodologies are timeless. Like Newton's laws, it's still relevant and applicable in modern geological and mineralogical research. 

The actual silver content often depends on the specific location and geological conditions of the galena deposit. Factors such as the surrounding rock types, temperature, pressure, and the presence of other minerals can influence the silver concentration.

From the Bronze Age to the Industrial Era

Metalliferous mining in Devon and Cornwall dates back to the Bronze Age circa 2300–800 BC (Northern Mine Research Society, 2024). The Romans also mined for metals in this region, including galena which is the natural mineral form of lead sulphide and an important source of silver (Merrington, Exeter, 2023).

According to the Historic Environment Record for Exmoor National Park, and Devon & Dartmoor HER Number MDV12545, the Old Combmartin Silver Mines in North Devon were highly productive in the Middle Ages and Early Modern period (Claughton & Smart, Historical Metallurgy, 2010).

The silver mined from Combe Martin provided the English crown and nation with a crucial source of revenue, coinage, and funding for military campaigns.

Combe Martin silver was a strategically important national resource for the kingdom over many generations. Devon's other silver mine is at Bere Ferrers on the south coast of Devon, eight kilometres north of Plymouth.

Both mines were under the direct management of the English Crown. The mines were known for their capital-intensive methods and innovative technology, which were quite advanced for their time.

In the 1290s, the output of Devon’s silver mines doubled after the construction of slightly inclined drainage galleries, which helped remove water from the hillsides.

In 1607, the English historian and antiquarian William Camden (1551–1623) authored a comprehensive study of the British Isles’ topography, titled “Britannia.” This is a significant work in the field of historical geography.

In his "Britannia", Camden states that King Edward III utilised funds from the Combe Martin mine to finance the war against France, which he led from 1312 to 1377 (Shackleford. K.W., Combe Martin Mines, undated).

Silver production from the Devon mines ceased during the Black Death that swept across Europe during 1348-9. The Bubonic Plague wrought a terrible toll, killing up to half of Europe's population.

By 1360, labour was scarce as Derbyshire mineworkers fled the silver mines (Combe Martin Silver Mines Society). Mining resumed at Combe Martin under Edward III, when England was one of the most formidable military powers in Europe.

Combe Martin's silver mines continued operating through to the Stuart period 1625-1649, providing a valuable resource to the Crown. It was not until the mid-18th century that mining was finally able to resume on a more consistent basis.

However, mining activities declined over time, with unsuccessful attempts to restart operations in 1800, 1813, and 1817.

In 1835, a new company began work on the Combe Martin site and uncovered ancient mining pumps, signaling the potential to revive the once-thriving industry.

Over the next several decades, the mines saw periods of renewed activity and investment. They had effectively ceased operations by the end of the nineteenth-century, as production became less economically viable.

Mine Tenement on Bowhay Lane, Combe Martin EX34 0JN, is essentially a closed working mine. Visitors can have a guided tour of the tenement, and look through their small yet detailed museum. Contact Combe Martin Silver Mines Society >

Besides the tenement on Bowhay Lane, and the adjacent Knap Down silver mine, the West Challacombe Silver Lead Mine is designated as a historical monument and it was active during the 1800s.

Today, the West Challacombe mine sett is heavily overgrown, and the only visible remnant is the waste pile or spoil heap. Located in the Exmoor region, it is documented in the Exmoor Historic Environment Record under the reference number MDE8262.

Update on The Mine Tenement Blacksmiths' Shop

Combe Martin Silver Mines Society (C.M.S.M.S.) informed us on 21.02.2024 that the Blacksmiths' shop was constructed after 1847, which aligns with the sale of the engine.

Beneath the blacksmiths’ shop, there exists a building that likely served as the Blacksmiths’ workspace when the engine was working. We are thankful to C.M.S.M.S. for this information.

The Old Combmartin Silver Mine Tenement

Information on the Combe Martin Silver Mines is available at Mindat online. The main workings lie in the Umber Valley on the northeast side, east of the parish church (Mindat.org, June 2024).

The silver mines, including the Knap Down sett, have an extensive history, with evidence of ancient workings dating back to at least the 13th century (Devon & Dartmoor HER, MDV789).

In 1528, the Old Combmartin Mines were reworked under the direction of the Höchstetter family from western Bavaria. The Höchstetter family were also involved in the Elizabethan copper-mining venture, known as the Society of Mines Royal (Donald, M.B., 1955, Elizabethan copper &c. 1568-1605).

There are indications that this may have been the site of the Fayes Mine, which was active from 1587 to 1594. Attempts were made to reopen the mine in 1646-1648, but the old workings were not properly drained.

Intermittent efforts to rework the mine continued through the 18th century. The mine was then reopened in 1813 but closed again after only four years of operation. A period of deeper mining occurred from 1835 to 1848.

In 1876, the section of the mine around the Harris's Shaft (grid reference SS58874654) was reopened by the Combmartin Mining Company and worked until 1880.

Remnants of the historical mining operations remain, including one wall, and foundations, a Cornish beam engine house with a remote chimney, an angle/balance bob pit, buttressed walls retaining spoil, a blacksmith's shop, and an account house.

There have been more discoveries since this article was published.

Documentary Evidence

The two certain aspects of the Combe Martin mines are well-documented, with records tracing their history from the first mention in 1292 up until their abandonment in the late 19th century (Paynter, Claughton, Dunkerley [2010]).

While the mines were worked intermittently during the late medieval period, documentary evidence indicates they were most productive in the 1580s and 1590s, under the management of Bevis Bulmer, a mining entrepreneur who came to Devon from the Mendip region (ibid).

According to Paynter, Claughton and Dunkerley (2010), production levels then continued, though inconsistently, through the end of the 17th century and intermittently in the 19th century. Mines were vital economic assets for the English crown over the course of many generations.

Although the Combe Martin mines stalled after four years in the 13th century, along with Bere Alston in the Tamar Valley they were a major centre of precious metal production in medieval Devon.

King Edward I 'Longshanks'

The reign of King Edward I (1272 – 1307) warrants a closer look. The Annales Londonienses; Chronicles of the Reigns of Edward I and Edward II (edited by William Stubbs, 1882) is a valuable collection of medieval chronicles that provide contemporary accounts, and perspectives.

The silver mining activities in Combe Martin occurred during the reign of King Edward I, whose 35-year rule was marked by both significant accomplishments and controversy. See this section's footnotes for references.

On the one hand, Edward I is remembered for his effective governance and implementation of important economic and legal reforms. He sought to centralise royal authority, improve the coinage, and change Parliament.

Besides instigating changes to government, Longshanks modernised England's legal system (Brain, J., Historic England). One of his key contributions was the development of the English Parliament (UK Parliament online).

Under his leadership, the meetings of this governing body became much more frequent, occurring approximately forty-six times over the course of his 35-year rule (ibid).

However, Edward I's legacy is also shaped by his aggressive military campaigns, notably the invasion and occupation of Wales and Scotland. He conquered northern Wales and made it a principality in 1284. Since 1301 the heir to the English throne has carried the title Prince of Wales (Britannica).

His brutal suppression of Welsh independence led to the revolt of Llywelyn the Last (c.1223 – d.1282), while the consequences of the Wars of Scottish Independence sowed the seeds for ongoing conflict in the region.

Additionally, Edward's heavy-handed government and taxation, as well as the expulsion of Jews from England in 1290, contributed to growing tensions and resentment among his subjects.

Thus, while Edward I presided over a period of economic and administrative progress, his rule was also characterised by controversial and divisive policies. His actions continued to shape the political, social, and cultural landscape of England, and the British Isles, for centuries.

Edward I's reign was a transformative but also a consequential period in the monetary history of England (Prestwich, M., 1969). In 1279, the king carried out a major recoinage, introducing several important new silver coins, including the silver Long Cross Pennies and the groat.

These reforms helped strengthen England's economy and provided a larger silver denomination that was more practical for larger transactions.

In summary, Edward I's complex legacy reflects the nuances of his long and eventful reign, which saw both progress and upheaval. The silver mining activities in Combe Martin occurred during this transformative Edwardian era.

Improved Record-Keeping under King Edward I (1272 – 1307)

The documentary evidence available from Edward I's reign is much more plentiful compared to earlier periods. Record-keeping and documentation within the Exchequer expanded dramatically during the late 13th/early 14th century period (Mate, 1972, The Monetary Policies of England 1272-1307).

Mavis Mate (1972) highlights significant growth in the size of the Lord Treasurer's and King's Remembrancer's Memoranda Rolls. This suggests that under Edward I, there was a significant increase in the volume and detail of records.

Historic Records and Archaeological Researches

Part of the extensive industrial history of Combe Martin: archaeological research and references to lost records point to silver mining in the town during the reign of King Stephen (1135-1154 CE). This aligns with Combe Martin's first ecclesial community under Manor Lord Robert Fitzmartin (see our Parish Church article).

In 2005, North Devon Archaeological Society dated Combe Martin's silver mining history back to 1135 AD, or earlier. "Researches have succeeded in pushing back the earliest date of silver extraction in the village by several centuries, to the 12^th century, at least" (NDAS: Newsletter 2, issue 9, spring 2005).

The Role of Silver in the 13th Century English Economy

In 13th century England, silver was a very important resource that was crucial to the economy. It was used as a form of money that people could use to buy and sell things.

In this era of strong central government, silver also served as a way for people to save and store their wealth, as well as a means for the monarch to collect taxes and revenue.

Thus the precious metal silver was an essential part of the 13th century economic system, and remained so into the 14th century (Hammersley, G., 1973).

The value of silver was used to regulate trade and commerce, finance military campaigns, and facilitate international trade. The Crown maintained control over the currency by minting silver coins and regulating their distribution, thereby curbing inflation and preserving the value of silver (Postan, 1984).

The Black Prince and Combmartin Silver

In the 1850s, Charles Dickens wrote that "the Black Prince [Edward of Woodstock, 1330–1376] certainly removed several hundred miners from Derbyshire to Devonshire, and from the mines about Combmartin, it is said that he obtained wealth sufficient to pay the expenses of his wars in France".

Dickens wrote his comments in Household Words (London, 1856), an English weekly magazine edited by Charles Dickens in the 1850s. Edward of  Woodstock, heir to King Edward III, became the Prince of Wales in 1343 CE.

Edward demonstrated remarkable prowess in battle, during England’s two significant victories against the French, in the initial stage of the Hundred Years’ War during 1337-1453 CE (Prestwich, M., 2005). 

These victories were achieved at Crécy in 1346 CE (Prestwich, M., 1977). And at Poitiers in 1356 CE, where the Black Prince famously captured and ransomed the French King John II (Fowler, K., 1972).

Other Victorian-era writers and topographers emphasized the significance of the silver from Combe Martin in supporting England's efforts during The Hundred Years' War.

However, the exact degree of its importance may have been exaggerated at times, and we explore these claims in the following sections of this article.

19th Century Mining in Combe Martin

In the 19th century, the Old Combmartin Mine Tenement on Bowhay Lane, also known as The Old Combmartin Silver Mine, served as a central hub for mining activities (Heritage Gateway MDV12545).

Regarded as the oldest silver mine in the village, Combe Martin Mine Tenement's essential structures encompassed an engine house, a chimney connected to a shaft, a powder house storing explosives, and a forge.

These facilities played a pivotal role in the mining operations during that era, contributing to the extraction and processing of valuable resources. The forge played a crucial role in processing the extracted silver and lead ores. Miners and skilled workers used the forge to smelt, shape, and refine metals.

The Environmental Impacts

It would be remiss to skip over the environmental impacts of Combe Martin's historic extractive industries. On the one hand, its mining industries provided an important source of revenue, and employment for the local population.

The village was rich in minerals, and self-sustaining Old Combmartin was all about industry, agriculture, crafts and artisanship. Not to mention its busy maritime trade in imports and exports.

In White's Devonshire Directory (1850), "COMBE MARTIN, or Combmartin, is a decayed market town". Yet the directory says the same about local settlements such as Hartland.

Various mining operations, quarrying, and associated infrastructure, changed the environment and the landscape, in ways that enabled the expansion of industrial activities and prosperity.

On the other hand, Combe Martin's polymetallic mining, quarrying and smelting industries also introduced pollutants into the air, waterways and soil. By the late-19th-century, critical topographers considered Old Combmartin an eyesore.

Given Combe Martin’s location in a steep valley, the waste from silver mining was disposed of downhill. This not only concealed traces of early industries but also buried the remnants of a large medieval hemp and fulling mill.

Charles Kingsley, Canon of Westminster in 1878, called Combe Martin a 'mile-long manstye'. This was reported by W. Pengelly in 1879, from Kingsley's paper titled North Devon, A Prose Idyl, which appeared in Fraser's Magazine, July, 1849.

Kingsley was also reprinted in Miscellanies, vol. ii., pp. 237-308 (1859). Kingsley's comments reflect the economic and social challenges facing many rural communities in England during the Industrial Revolution .

Timber for Combe Martin's numerous local industries was provided by deforestation, which transformed the landscape and ecology. The effects on Combe Martin's landscape are still visible today.

Combe Martin's Mineral Heritage

Besides silver-lead: Combe Martin boasts a wealth of accessible natural minerals, ores and pigments. The River Umber, running through Combe Martin, was named after its umber pigment. 

Evidence of historic mining operations can be found in the northern, southern, eastern and western sections of Combe Martin. Thanks to local geographical features, besides the central Mine Tenement there are old mining adits around Combe Martin, including at the harbour and on the cliffs.

Mine Adits

Mining operations often include underground structures called adits or stulms. These near-horizontal tunnels are dug into the main mine workings at the lowest possible levels (Mindat.org, 2024).

Adits serve multiple purposes beyond just providing an entrance to the mine. If driven through a hill or mountain to the surface on the opposite side, an adit becomes a tunnel (ibid).

Adits are an essential means of ventilation for the mine, allowing fresh air to circulate underground. They have long played a vital role in draining water from mines, certainly in Devon and Cornwall.

By providing a low-level exit point, adits allow water being pumped up from deeper levels to be discharged outside the mine, rather than having to be brought all the way to the surface.

This solution provides a practical and cost-effective drainage function for mine owners. It saves them time, effort, and significant costs of transporting large volumes of water to the surface through the main shaft or other means.

The adit system is therefore a crucial component of efficient and cost-effective mining operations.

Advantages of Valley Mining

Similar to Cornish valley mining, the steep valley sides and cliffs of Combe Martin made it easier to prospect and dig for minerals, and to drain the workings of groundwater. Exposed rock, gravity, and the ability to drain groundwater from the mines were all crucial, allowing for deeper and more extensive mining.

Smelting and Furnacing Fuels

Coal, charcoal and anthracite culm were used in local mining and lime-burning operations. These solid fuels were employed to power the smelting of silver and lead, iron and tin, commonly in smelt mills, bloomeries and blowing houses.

These practices may have medieval origins, and were in place up to a century before the widespread use of coal in lead-smelting with the more efficient reverberatory furnace (Tylecote, R.F., 2002).

Also used to fire up to nineteen lime-burning kilns in Combe Martin: imported coal and culm were sourced from Wales, renowned for their coal production. Imports were landed at Combe Martin harbour and were stored in a culm hay near the beach limekiln, or moved to the mines and quarries around the village. 

The New Combmartin Silver-Lead Mining Company (1864)

In 1864, West Challacombe, and Lester Cliff at the harbour beach, were investigated by the New Combmartin Silver-Lead Mining Company (Exmoor National Park HER MDE8262, West Challacombe Mine [Monument]). The ventures failed with little or no production (ibid).

There are shafts and an adit between 200 and 300 yards south of West Challacombe Farm. There is also an adit in the cliff at Combe Martin's Lester Point (Exmoor National Park HER MDE8262 - West Challacombe Mine [Monument]). Open a map of this area ˃

A Mining Spurt at the Old Combmartin Silver-Lead Mines (1875)

On December 11, 1875, The Mining Journal (Volume 45, Issue 2103) noted a significant increase in mining activity in Devonshire (p. 1367). The journal stated that the Combmartin Silver Lead Mines had a long and storied history.

In 1867, local Dr. A.S. Kingdon had presented a paper at a meeting in Barnstaple. In his remarks, Dr. Kingdon reminded the delegates that the Combmartin lode had previously been worked for silver in 1818 and again in 1835.

The company that began operations at the Combmartin lode in 1835 was successful, returning over £60,000. Citing this prior productivity, Dr. Kingdon advocated for renewed mining efforts at the Combmartin lode in 1837.

However, the mines lay dormant for a while until late in 1875, when a group of speculators from Exeter restarted operations in a promising area, with a good chance of success. 

Combe Martin Silver Mine Shares Sold in 1876

In 1876 a new company was formed to work the Combe Martin silver mines. Shares were priced at £2 each - worth around £300 today - "to make them within reach of the many" (The North Devon Journal). We discovered that a well-appointed hotel was built in Combe Martin as a direct result of this new venture:

The Valley Hotel at Combe Martin (prop. William Dennis), listed in White's Directory for 1878, was built between 1876-1877, in anticipation of increasing requirements. This was consequent upon the mines being worked.

Harris’ mine was initiated in 1876 and operated for four years. During this period, the North Devon Journal published a report about a visit to the mine, noting that both the 27 and 37 fathom levels were producing ore.

The Combe Martin Silver Mines in 1877

From records we know that, in 1877, the Combe Martin Silver Mine was managed by the Combmartin Mining Company. J. Watson was the secretary, and the manager and chief agent were John Comar (possibly Comer) and C.H. Maunder.

Our source is the Mineral statistics of the United Kingdom of Great Britain and Ireland for the year 1877. Published in 1878 by Robert Hunt F.R.S, Keeper of Mining Records.

In the west of Combmartin, The West Combmartin Silver Lead Mining Co. (Frederick Thomas), was managed by the West Combmartin Silver Lead Mining Co. The manager and chief agent were W. H. Hosking and John Treweek (ibid).

Silver Mining Faltered in 1878

However, in June 1878, The Mining Journal No. 2233 Vol. XLVIII reported that the mining operations had "come to grief". "There never seems to have been sufficient spirit thrown into the concern".

"The brunt has had to be borne by the few instead of the many. It is a pity, for the prospects seemed fair enough, and what has been may yet again be" (p. 623). From available reports we may conclude that profitable industrial silver mining in Combe Martin had ceased by 1880.

When Silver Mining in Combe Martin Became Unprofitable

Local silver mining had been profitable well into the 19th century, but Combe Martin’s rich silver deposits are unique insofar as they do not run in continuous lines. 

During the 1870s, the local geology would have had significant implications for the mining operations conducted by the New Combmartin Silver-Lead Mining Company, and others in the area.

The geology may also explain why, despite Combe Martin's high silver content,  operations in the 1870s did not result in significant production. The intermittent nature of the deposits would have made consistent extraction difficult, and potentially unprofitable.

At Combe Martin by 1880: high costs, economic challenges and fruitless searches had virtually ended local mining for silver-lead. In May 1880, calls were issued to revive mining in the village. At that time: lodes on the western and southern flanks of Combe Martin, and at the harbour beach, were unexplored.

In one of the last references to old Combmartin silver mining: a letter dated May 11, 1880 was printed in the Mining Journal Trade Magazine Supplement (GPO Newspaper). It proposed that a potential lode of silver should be worked at the western side of Combmartin:

MINING IN THE COMBMARTIN DISTRICT.

SIR
Hearing that a gentleman of considerable mining experience intends paying Combmartin a visit very shortly for the purpose of inspecting some mining property on the west side of the valley, where little or nothing in the way of mining has ever been done, I would venture to suggest that a visit be paid to some property adjacent, belonging to Mr. John Boyle.

There are said to be several well defined lodes running through the property, which can be very easily worked, and which certainly ought to be opened out. It is the candid opinion of the inhabitants of this village that could any one be found sufficiently spirited to make a fair trial on this property, something rich would shortly be discovered.

There are splendid advantages of situation, water, &c., and any practical man would confess that a thorough trial of the whole of the lodes could be accomplished for a very small sum.

From Silver Mining to Growing Strawberries

Contemporary records and surveys indicate that the last Combe Martin silver- lead mine had closed by 1890, and that the mines were abandoned. In 1904, it was reported that "the mines had been closed for forty years and were unworkable". However, Combe Martin had already turned to market-gardening.

Medieval Silver Mining in England

From the 12th to the 15th century: silver mining in medieval England was a continuous activity involving several changes in production and practices.

Various areas, such as Cumberland, Durham, Northumberland, and Devon, were sources of silver which was extracted using techniques such as strip mining, bell-pits much like a well shaft, also trenches and tunnels. Silver was a precious metal for the royal mint, the church, and the international trade (Allen, M., 2011).

The lead at St Peter Church in Barnstaple is believed to have originally come from Combe Martin. "It is rich in silver, which would account for its particularly good colour" (Ward Lock and Co., Illustrated Guide, 1930s).

In 1835, the North Devon Journal reported that the roof of St Mary Magdalene's Church in Barnstaple is made of Combe Martin lead.

Antiquarian Records of Old Combmartin Silver Mining

The author and antiquary William Camden (1551-1623) in his survey Britannia (2nd ed. transl. from Latin, publ. 1722), wrote that "the Combmarton [sic] silver mines [North Devon] were first discovered in the days of Edward I".¹

In Britannia, Camden reported "some old lead-mines [? r. Elizabeth I ?]" at Old Combmartin, and that "the addition of Martin [to the old British toponym Kum or Combe] to the village name, is from Martin de Tours a Norman Lord, who had great possessions here in the time of Henry I" (Britannia, posth., 1722, p. 47).

Queen Victoria Purchased Combe Martin Silver in 1848

In 1848, Queen Victoria purchased items made from the Combe Martin silver mines (Peter Christie, A North Devon Chronology). Victorian and Edwardian costume items included brooches, pins, charms and thumb-bells (thimbles).

Ellis and Son Silversmiths of Exeter

Worked by Victorian silversmith Henry Samuel Ellis of Exeter (mark HSE): antique items of Combe Martin silver bear historical city hallmarks for Exeter, the Combe Martin silver mines, and design patent stamps. They are still collected today.

Ellis and Son advertised that their spoons were made with silver from the Combe Martin silver mines. At the Great Exhibition of 1851, Henry Samuel Ellis & Son of Exeter— Inventors, Designers, and Manufacturers displayed a Combe Martin silver-wire gauze [mesh] jewel-casket with a silver knitting-basket.

Finds at the Old Combmartin Silver Mine Tenement

Silver-mining really means workings for lead-ore with a high silver content. Historic England states that the Old Combmartin Silver Mine a.k.a. 'Fayes Mine' on Bowhay Lane is of historic importance because it is a documented Medieval Mine (LEN 1350386).

"Pottery recovered suggests site was also in use during Medieval and Post-medieval periods" (Devon and Dartmoor HER No. MDV31337). The Mine Forge, constructed in 1837, features a steeply pitched slate roof with gabled ends. 

In 2004, a significant collection of pottery sherds was discovered at the Mine Tenement (Dunkerley, T., 2004, SDV339645). Reported by local archaeologist Trevor Dunkerley, this diverse assemblage provides fascinating glimpses into different historical periods:

Among the findings was a sherd (broken ceramic) of Roman Black-burnished ware, dating back to the second or third century. This type of pottery was known for its glossy black surface achieved through burnishing techniques (ibid).

The finds included medieval sherds spanning from the 13th to the 16th centuries. These fragments offer insights into the daily life and material culture of people during the medieval period.

Notably, a sherd from a 16th-century Spanish tin-glazed dish was also part of the assemblage. Such imported ceramics reveal connections beyond the local context.

An intriguing find was a 13th-century church pavement border tile. This tile likely adorned the floors of a nearby church, linking the mine site to broader architectural history.

Additionally, a probable loom weight with a diameter of approximately 7 centimeters was recovered. Loom weights were essential tools used in textile production during various historical periods.

These finds provide a tangible link to the past, allowing us to piece together the stories of those who lived and worked in the vicinity of the Mine Tenement.

Outlying Mine Works 

The Exmoor Historic Environment Record indicates there are also silver-lead workings around Berrynarbor and Watermouth on the edge of Combe Martin.  The oldest of these workings is situated near the Iron Age univallate hillfort 'Newberry Castle', dated to c750 BC to AD43 on Newberry Hill.

Devon and Cornwall Silver | Combe Martin Ores and Smelting | English Civil War

The Romans in Britain

The Romans stayed in Britain for nearly four centuries, and silver became widely used for coinage in the Roman world from the 7th century BCE onward. The  Roman silver denarius (pl. denarii) was their principal silver coin, and the backbone of the Roman economy until the 3rd century CE.

Combe Martin Silver During the Anglo-French Wars

The Combe Martin mines were exploited for the Crown's coffers during England's medieval wars with France, and yielded good amounts of silver in Tudor times. Read more on the history of Combe Martin silver in White's Gazetteer (1878-1879).

Also see: Was there Combe Martin Silver in English Civil War Coinage?

King Charles I Encouraged Silver Mining in Combe Martin

There is some evidence that Royalist bullets were made from the "distressed" Combe Martin silver-lead mines during the English Civil War (1642-1651). Some have argued that these mines produced silver for the Royalists, yet in Amery's Devon & Cornwall notes & queries (1911) we find:

"It cannot well have been Combe Martin ; there is an extant letter from one of Fairfax's lieutenants in February, 1646-7, saying that Sir Thomas Bushell intended to employ himself in "recovering the distressed works of Commartyn myne."

Amery thought it "highly probable that the [Combe Martin] mine then yielded only lead for bullets, there being neither time nor opportunity for extracting the silver from the ore" (Devon & Cornwall notes & queries, 1911). He seems to have been mistaken:

The Coinage of Coombe Martin 1647-1648

According to Lt. Col. H. W. Morrieson, F.S.A, published by the British Numismatic Society (undated) "Bushell spent most of his time between February, 1646-7, and May 1648, at Combe Martin". Morrieson posited that the Combe Martin mines produced a small issue of silver coins after a slow start. 

Read more about Combe Martin English Civil War money˃

Morrieson deduced that there was only a limited quantity of silver accessible for coin production at this time: apart from the groat and threepence, the remaining denominations were uncommon, especially the top three categories. This suggests that the minting was likely a minor operation (Morrieson, undated).

H.W. Morrieson F.S.A. seems reliable, having authored several works on the coinage of the 17th century, generally on the period of the English Civil War. His research provides valuable insights into the historical context of coin production and usage in this period.

According to Plymouth geologist and historian Richard Nicholls Worth F.G.S. (1895) verbatim: "the [Combe Martin] silver mines were opened in the year 1648, but without much being done, though the project was personally encouraged by the King" (A History of Devonshire). 

The Last Explorations in Combe Martin

During the 19th century the old Combmartin mines were worked again, and new ones opened. Worth states there was no significant yield during the last explorations. Yet "the ore was rich, yielding 140 and 150 ounces of silver to the ton" (ibid) [which equates to approximately 0.42% of an Imperial ton].

The works of R.N. Worth provide a detailed account of the trades and occupations in Combe Martin.

Notable Uses for Silver and Sulphides

Silver is associated with lead ores, mainly lead sulphide galena, but also silver-rich tetrahedrites (a noxious antimony sulphide of copper, iron, zinc, and silver).

Used for coins in the 7th century and more commonly in the 12th century: silver is found in antiquated ornaments, in old jewellery, and in church plate made of precious metals.

Silver is valued for its sheen and for its antibacterial properties. Besides its bullion value and once being essential for coinage, silver is intrinsically linked with aesthetics, state assets, historic milestones and events, and sentimentality.

Devon's Medieval Mines and Contributions to Mint Output

Martin Allen (2011) states that "Devon silver made a significant contribution to mint output, during times of bullion scarcity in the 1290s". The same silver especially mitigated the effects of the Bullion Famine in the mid-fifteenth century, when Europe suffered a severe shortage of precious metal.

The roots of the Great Bullion Famine during the 1400s were in the exhaustion of European silver mines ('the eyes had been mined out of them'). Adding to the crisis were European trade deficits with Middle Eastern and Far Eastern countries (ibid). 

Allen contends that the greater source of the metal in the English currency was imported silver rather than locally mined silver. Moreover, gold coins constituted most of England's money supply from the mid-fourteenth century onwards.

William Camden's Report on the Combmartin Silver Mines 

Antiquarian scholar William Camden said of the Combmartin mines, "the first fynding and working of which ther are no certain records remayninge. In the tyme of Edward the first they were wrought [sic]" (Camden, in Besley, H.,1901, The Route Book of Devon &c).

According to Charles G. Harper (1908): in 1296 “was brought to London, in finest silver, in wedges, 704 lbs and 3 dwt [pennyweights]. [The total equates to 320 kilograms]. And the next year 260 miners were pressed out of the Peak and Wales—and great was the profit on silver and lead.”

In the reigns of Edward III and Henry V, the Old Combmartin silver mines were found very useful in defraying the costs of the wars in France (Camden, in Britannia). But for more than a century and a half afterwards the industry declined, to be revived in the reign of Queen Elizabeth I (ibid).

Camden wrote the first detailed historical account of the reign of Elizabeth I. He continues [sic], "But in the tumultuous raigne of his sonn [the Combe Martin mines] might chance to be forgotten, until his nephew, Edward the third, who, in his French conquest made good use of them". 

"And so did Henry the fifth ; and lately in our age, in the tyme of queen Elizabeth, there was found a new lode in the lande of Richard Roberts, gentleman, first begann to be wrought by Adrian Gilbert, Esq., and after by [engineer] Sir Beavis Bulmer, knt." ([sic] Camden).

These adventurers provided the working expenses, and agreed with the landowner Richard Roberts for half-profits. Camden wrote that through Bulmer's mineral skill: "great quantities of silver were landed and refined, of which he gave a rich and fair cup to the Right Hon. William [Pulteney], Earl of Bath".

William Pulteney, 1st Earl of Bath, Privy Council (22 March 1684 – July 1764) was an English Whig politician and peer under George III. His seat was at Tawstock near Barnstaple (Chugg, 1980). 

Lead Smelting in the Centre of Combe Martin Village

Excavations at Christmas Cottage on Church Street, reported in 2010, revealed undisturbed accumulations of material from the early medieval period to the present day. The material included dense, heavy, black and grey green smelting slags thought to be lead smelting. Also found were large quantities of quartz.

See Paynter, Claughton and Dunkerley (publ. Oct 2021): Further work on residues from lead/silver smelting at Combe Martin, North Devon.

What's all the fuss about Silver?

Mine workings run through the main street of Combe Martin (Stuckey, 1965, p.5). There is a tale that Combe Martin silver is in the Crown Jewels.

Certainly, Combe Martin sterling silver items are found in the London Mansion House Plate Collection; and Combe Martin silver continues to be sold on the open market. 

Today, thousands of metric tons of silver are mined and consumed worldwide.  Ancient products from Combe Martin survive; there are 16th century items in London. 

The London Mansion House Plate Collection

In 1593, engineer Sir Beavis Bulmer had Medley Goldsmiths - of Foster Street in London - make two fine cups from Combe Martin silver.

One of those cups weighing 137 ounces was given by Queen Elizabeth I to Sir Richard Martin (Goldsmith), who according to the Livery Committee was Lord Mayor of London and Master of the Mint during 1594. The cup bears the date 1593 (Lewis, 1858). 

The London cup was melted down in 1643, but the silver was used again and still survives in the form of three tankards (Chugg, 1980, Devon: a Thematic Study).

A tankard made of Combe Martin silver is on display in Combe Martin Museum, on Cross Street. It is a copy of a Combe Martin silver tankard kept in the City of London Mansion House, now the official residence of the Lord Mayor of London.

The Mansion House Palace gold and silver plate collection is one of the largest and finest in the world. It includes bowls and vases, flagons, rosewater dishes, candelabras, cups, cigarette boxes, wine labels, and cutlery.

The Mansion House plate collection is regularly used for ceremonial events, serving as both decoration and tableware throughout the house.

The Combmartin Silver Mines Reported by John Banfield (1840)

According to Besley's Route Book Of Devon &c. (1901), the silver mines were re-opened in 1813, and worked for several years. They were opened again from 1835, and were also working in 1901 (p. 83).

Ilfracombe publisher and gazetteer John Banfield agreed that the Combmartin mines were re-opened in 1835. He wrote that "three steam engines and other machinery were erected by a company with a capital of £30,000, about half of which was expended before any important discovery was made."

The shafts were on the point of being abandoned, when a lode was found which offered a fair prospect of remuneration. However, three dividends had to be paid, besides defraying the expenses of about £500 a month (ibid).

Banfield states the works were ultimately closed after the lode became poor; this "was a great loss to a poor and extensive population." (1840, p. 64).

During 1842, the local Journal reported that a plate weighing 5 pounds and made of Combe Martin silver, was put on show to prove the mines were flourishing.

A Description of Combe Martin Silver Mines in 1871

The Imperial Gazetteer of England & Wales (1871) reported that "Combe Martin's  silver-lead mines were last resumed in 1835 and had shafts between 20 to 120 fathoms deep. They yielded between 20 and 168 ounces of silver [up to 0.53%] per ton of ore".

The Imperial Gazetteer of England & Wales topographical dictionary was first published between 1870 and 1872. Edited by the Reverend John Marius Wilson, this invaluable historical resource contains a detailed description of every county, city, borough, civil parish and diocese in England and Wales.

Antique Silver Thumb Bells (Thimbles)

The fashion for collecting thimbles was popular in England during the Victorian and Georgian eras, when silver thimbles were considered ideal gifts for women, who sometimes wore a waist hook device called a chatelaine to which sewing items or keys would be attached.

In England, silver thimbles also commemorated 19th-century British coronations; and ceramic thimbles are still sold today as tourism mementoes. Nowadays, silver thimbles are collectors' items; and the rarest and most intricate thimbles are valuable. Read more at the London Thimble Society.

London's Great Exhibition of 1851

Combe Martin silver is listed in the 1851 Descriptive and Illustrated Catalogue for The Great Exhibition; the international fair held in London during 1851.

That exhibition was the first ever international exhibition of manufactured products; and it set the precedent for international exhibitions over the following 100 years.

It was the most successful and memorable event of the century. From May to October 1851, Hyde Park in London was packed with over six million visitors to the ‘Great Exhibition of the Works of Industry of all Nations’. (The Gazette: The Great Exhibition of 1851. 2023). 

Silversmith Henry S. Ellis of Exeter

Henry Ellis & Son; watchmakers, jewellers and silversmiths active 1825-1905, were successful Exeter goldsmiths and opened their first shop at 200 Exeter High Street. A watchmaker by trade, Henry Ellis traded in pieces made in Exeter,  Birmingham and London.

In 1847 the eldest son, Henry Samuel Ellis, registered the firm’s design for ‘Patent Safety Chain Brooches’ including rare pieces made from Combe Martin silver (Exeter Ramm, 2023). Ellis made a variety of patented brooches such as shawl clasps (Chugg, 1980, Devon: a Thematic Study, p. 129).

These clasps incorporated a recess in which the point of the pin could be safely housed. Some of these brooches were manufactured in Birmingham, but both the Exeter and Birmingham examples have ‘Combmartin Silver’ inscribed on their backs (ibid).

After Queen Victoria purchased five Combe Martin pieces: Ellis & Son were appointed silversmiths in ordinary to the Queen in 1848, exhibiting at the Great Exhibition in 1851. In effect they were given the Royal seal of approval.

Ellis was Exeter Mayor in 1868, and his items of silver such as cloak pins and shawl brooches (1847-8) are rare (he died in 1878). 

These were among many pieces smelted from ores raised at the Combmartin mines; and they bear the Combe Martin hallmark. The Ellis business was founded by Henry Ellis Senior (1790-1871), continued by his son Henry Samuel Ellis, and then by his grandson William Horton Ellis.

This information is sourced from The Great Exhibition 1851; Official and Descriptive and Illustrated Catalogue (Vol. 2, p. 671, 1851). Also from the British Library and the Exeter Royal Albert Memorial Museum (2023).

Combe Martin Silver Mine Shares Sold in 1876

In 1876, a new company was formed to work the Combe Martin silver mines. Shares were priced at £2 each - worth around £300 today - to make them "within reach of the many.' (The North Devon Journal).

'Quantities of Combe Martin Silver Remained Unworked'

John L. W. Page wrote in 1895, that towards the close of silver-mining in old Combmartin, "miners reported there were lodes beneath Combe Martin Bay, close inshore, and not more than three or four feet from the surface. At Knap Down, a quantity still remained unworked" (The coasts of Devon and Lundy Island).

Old Combmartin's Reciprocal Ores Trade with South Wales

In the 17th-19th centuries, apart from being a busy agricultural centre, North Devon was heavily mined for both iron and copper on Exmoor. Hundreds of tons of these ores were mined in Combmartin, which had strong links to South Wales for supplies of coal and lime, and reciprocal trade.

Links With Cornwall and Wales

There is a historic relationship between Combe Martin, Cornwall and South Wales, which still lingers in the local dialect and monuments. Aside from a long-running trade in ores and bulk cargoes, there was a significant movement of miners back and forth between Wales, Cornwall, Exmoor and Combe Martin. 

Overground and Underground Mining Operations in Combe Martin

Combe Martin's mine workings stretch for almost two miles along the entire length of the borough. Evidence of underground and overground mining operations - trenches, tunnels and mines in Combe Martin - have been found at numerous locations along both sides of the valley.

Rich Geological Formations on Exmoor

North Devon has rich geological formations dating back over 350 million years. Great quantities of silver-lead and iron, and some manganese and copper, were mined in Combe Martin. And to a great extent, lime was quarried and burnt for agricultural use. Large quantities of lime putty were used by local builders.

The Copper Development Association (2023) states that the pinnacle of British copper mining happened during the early 19th century. Britain accounted for over half of the global output, with the majority being extracted from Cornwall.

Industrial needs were growing rapidly, which led to a large quantity of copper being imported from abroad including Chile. Russia was a significant producer.

However, by the end of the nineteenth-century, the availability of large quantities of foreign-mined metal, combined with the exhaustion of Cornish mines and the difficulties and expenses caused by water in the workings, reduced the output of Cornish ore from 18,300 tons per annum to virtually nothing.

However, by 1933, the world's output from smelters had risen from 291,000 tons in 1852 to approximately three million tons annually. The singular cause for this expansion was rapid development in the electrical engineering industry.

The Romans and Lead Mining in Britain

The lead mines of Britain were worked by the Romans from the earliest days of their occupation of the island. Pigs of lead have been found in the Mendips, stamped with the titles of Britannicus (A.D. 44-48) and Claudius (A.D. 49).

The British lead-ore mining industry continued after the Romans departed.

Ancient Lead Pig Ingots

Lead Pig ingots have been found in cargoes from ancient Mediterranean  shipwrecks. Lead Pigs (or Pig lead) are similar to lead ingots; they can be re-melted for casting other lead products.

Pig lead can also be used as ballast weights or anchors in other industrial or marine applications. 

Mining in England Before the Thirteenth-Century

Before the 13th century, silver-bearing ores were largely mined in northern England, such as Derbyshire, and customary regulation (local custom and practice rather than national laws) allowed entrepreneurs to exploit rich but shallow resources (Rippon, Claughton & Smart, 2023).

The First Sterling Silver

In 1300 Edward I enacted a statute requiring that all silver articles must meet the sterling silver standard of 92.5% pure silver (925). To prevent frauds, the first Standard mark placed on silver to guarantee its level of purity, used from 1300, was the leopard’s head.

King Edward Longshanks' Statute

‘No goldsmith… shall from henceforth make or cause to be made any manner of vessel, jewel or any other thing of gold or silver except it be of the true alloy […] and that no manner of vessel of silver depart out of the hands of the workers, until further, that it be marked with the leopard’s head' (The London Assay Office, 2023).

In 1327 Edward III granted a charter to the Worshipful Company of Goldsmiths to assay all silver and gold mined in England. 'Les Gardeins du Mester’ (Guardians of the Craft) were required to test the silver and mark it with the ‘King’s mark’, the leopard’s head. A crown was added to the Standard mark in 1478 (Edward IV). 

Silver Hallmarks

Hallmarks were applied by trusted guardians of the craft, going from shop to shop. Hallmarks are not trademarks or maker's marks - a true hallmark must be guaranteed by an independent body or authority certifying contents are as marked. Therefore a stamp of '925' by itself is not a hallmark, it is an unattested fineness mark.

Mines Under Direct Crown Management

The Crown had been engaged in silver-mining since at least the twelfth-century, yet the thirteenth-century break from customary regulation, in Devon and elsewhere, was unprecedented.

Mines in Devon came under direct Crown management, and mineworkers were often pressed into service as direct employees of the Crown. 

Mining became a large scale economic operation, and while it must have been carried out much earlier here, Combe Martin came late to the medieval silver-mining scene.

Early silver mining was primitive and hard, and from early times the mines were generally closed over winter, due to rising groundwater levels. 

The measurement of groundwater or the water table is dependent upon the season. In the summer season the groundwater tends to get low because of dryness and evaporation. It swells in abundance during the rainy season and in the winter season. 

The Medieval Economy

The most important economic resource in medieval Europe was silver. It had been highly valued since the Romans, for the advancement of civilizations, and for international trade.

The Vikings used hacksilver for trading and reserved assets, as bullion and as currency by weight.

Fundamentally an agricultural society, England's mining of iron, tin, lead and silver, and later coal, played an important part within the English medieval economy (Claughton, P., 2010).

Monarchs, investors and governments have always turned to precious metals in times of crisis, especially to support themselves, their wars and their economies. 

Bullion has been kept as a reserve asset over millennia - not in general circulation - by governments and by central banks.

Silver was much more abundant than gold, and during silver-mining boom periods it was universal and a common means of exchange or currency.

Vast Wealth of Combe Martin Silver C13-C14

From 1290 onwards (Edwards I & II) until 1340 (Henry VI) in Combe Martin, "£4,046 of silver" (about £2.9 million today) and "£360 of lead" was obtained (Combe Martin Silver Mines Society). 

In 1295, King Edward I sent Derbyshire lead-miners to work in Combe Martin. Additional labour was recruited from six English counties, and from Wales.

The Frescobaldi Merchant Bankers C13

In 1299 the mines were leased to the Frescobaldis of Florence, merchants and money lenders. The English monarchy relied heavily upon the great firms of Italian merchant-bankers in its employ, selecting its financiers from the greatest companies.

Stuckey, 1965, p.6.  & Richard W. Kaeuper (2015): "Kings, Knights and Bankers", pp. 43-92.

Combe Martin Silver Enriched the Treasury of Monarchs

From Edward I forward, the Combe Martin mines were worked intermittently under Henry IV (Henry Bolingbroke) (1367 – 1413) but mainly by his son Henry V (1386 – 1422) to finance his wars in France.

This is all according to Thomas Westcote (1567 – c. 1637), English historian and topographer of Devon (A View of Devonshire, c. 1630).

In 1822, Rodmarton rector and topographer Daniel Lysons wrote that "the lead mines of this county and of Cornwall are more enriched with silver than those of any other part of the kingdom..."

"...The produce of the mines at Combe Martin and Beer Alston, is said to have been unusually great in the reigns of Edward I. and II., and to have much enriched the treasury of those monarchs" (Daniel Lysons, 1822).

Magna Britannia; being a concise topographical account of the several counties of Great Britain (1822).

Combe Martin Silver Funded the Hundred Years War?

Referring to rumours that the Combe Martin mines 'supported the wars of Edward III and Henry V' (the Hundred Years' War): Dr Peter Claughton considers them "wide of the mark" (2000). We are not, however, going to argue with Dr Claughton nor with Combmartin's esteemed local historians.

Yet while local silver would have helped, Dr Claughton may have a point. For by 1339, two years after hostilities began with France, Edward III himself, and large-scale borrowing, had already raised hundreds of thousands of pounds.

The coffers were bolstered by taxation raised through parliamentary grants. Also by fundraising and by open lines of credit to the monarch. The powers of the monarchy in medieval England were virtually unlimited, and Edward exploited them. He had credit and funds readily available for emergencies,

Even the Great Crown - St Edward's Crown, the centrepiece of the Crown Jewels - was used as security (Moorhouse, 2021).

Claughton argues that Combmartin's mines had been abandoned after only two years production in 1294. Attempts to rework them, under a succession of lessees in the late 1320s, failed.

Claughton also maintains that the quoted size of the mining workforce during the 1290s, over 300, are those for Devon as a whole. Most of the miners were used at Bere Ferrers (Claughton, 2000). That's all we are going to say here.

The Principal Silver Mines Opened in Devon

The principal Devon silver mine opened up by the Crown in 1292 was at Bere Ferrers, to the north of Plymouth on the border with Cornwall (Dr Peter Claughton, 2010).

Other mines at Combe Martin were opened at the same time, but abandoned by the Crown by 1296 (The Crown Silver Mines &c., pp. 299-308). 

The scholar F.J. Snell stated in 1895 that "the mines were known to have been exploited in the reign of Edward [Longshanks]. Grants were made to the miners by Edmund, the King's younger brother, and confirmed by charter in 1305".

"Great was the Profit in Silver and Lead"

Reference to lost records suggest that Combe Martin silver mining was carried out in the 12th century (Devon and Dartmoor HER, MDV12545). And Victorian scholars refer to Combmartin silver as funding the Hundred Years War (1337–1453). 

In 1895, scholar F.J. Snell, contributor to the Encyclopaedia Britannica, also claimed that "the land battles of Cressy and Poitiers, and the battle of Agincourt too, were won in the shafts of Combmartin" (1895, p. 52). 

Combe Martin's Mining Monuments

Mine workings exist from Combe Martin beach to the landmark Hangman Hills, up to Combe Martin Knap Down and Holdstone Down, and two miles east. Tunnels also run under the length of Combe Martin High Street. 

In addition to Bowhay Lane (G+ 5XXH+VH Ilfracombe), there are mining monuments all over Combe Martin; at Lester Point, at West Challacombe, on the Hangmen Hills, and two miles east towards Trentishoe.

West Challacombe Silver Lead Mine was active during the 1800s. The workings are now very much overgrown and only the spoil heap is visible. Sites and workings at West Challacombe and on Knap Down are "ancient" but they cannot be dated accurately.

Prospecting for silver lead was apparently happening in the mid 1850's at West Challacombe. Refer to the Historic Environment Record for Exmoor National Park; www.exmoorher.co.uk/Monument/MDE8262.

Several adits lie out of sight on the Hangmen cliffs, and some of these sheer cliffs and slopes should be considered highly dangerous.

At the precipitous cliff base of The Rawns in Combe Martin - elevation 72.5 metres - two short adits are thought to have been for iron or manganese, and associated with the nineteenth-century Girt Down Mine sett. The grid references are SS 5930 4830 and SS 5937 4835.

Cornish Pumping Engines

A Cornish pumping engine - usually housed in an engine house - is a type of steam engine developed in Cornwall. Sometimes called 'wheelhouses' in Cornwall, in this context the engines mainly pumped water from a mine. The Cornish beam engine uses steam at a higher pressure than other engines.

Michael G. Gichard (April 2007) wrote that in Cornwall, the beam of the engine was commonly referred to as the Bob. The engine houses were designed with a rectangular layout (see photos).

The front wall, known as the bob wall, was constructed from heavy granite to bear the weight of the bob and resist the stress caused by its rocking motion.

The cylinder was securely fastened to a base within the engine house. The chimney was positioned at one of the back corners of the engine house, while the boilers were housed in a separate building nearby. Engine ponds, used to store water for the condenser, were situated close to the engine house (ibid).

The pump rod shaft was placed directly in front of the engine house, right beneath the outdoor end of the bob. The pump rods were typically made from Scandinavian or Canadian timber, measuring up to 24 inches square at the top end.

It was common practice not to pump the water all the way to the surface. Instead, the water would be lifted from the deepest parts of the mine to a midway point, from where it would be discharged through an adit to the surface or the sea (Gichard, 2007).

In the late 1830s modification by James Sims, a unique double cylinder was designed. The cylinder with high pressure was positioned on top of the cylinder with low pressure. There was a constant connection between the bottom side of the small cylinder’s piston and the top side of the larger one (ICE Publishing).

The steam, after it had driven down the small piston, expanded under the large piston, and raised it. In that way, and in that sense, Sims’s engine was double  acting. Sims's engine design effectively addressed the practical challenge of keeping the combined cylinders aligned both vertically and parallel to each other.

The expensive but much credited Cornish pumping engine was also used for powering man-engines, for getting underground miners to and from their working levels. They also winched materials into and out of the mine, and powered on-site ore stamping machinery. 

Silver-Bearing Galena

Galena, also called lead glance, is the natural mineral form of lead-sulphide. Silver-bearing Galena (PbS with Ag) or argentiferous galena is the most important ore of lead (Pb, plumbum), and an important source of silver (Ag) - (Mindat.org, 2023).

Usually, the silver is present as tiny inclusions of various silver sulphosalts. By the 19th century, Combe Martin's lead mines were worked not so much for silver, but rather because of the high market value of lead. 

According to heritage records, in 1292 the Crown opened up new silver mines in Combe Martin, which closed again in 1296. Work restarted in the 1320s, and up to 1330 the mine was leased by five separate individuals including the lord of the manor (Heritage Gateway, 2023).

The Boom Period for Silver Mining in Combe Martin

The late 16th century was the most productive period for silver in Combe Martin, partly due to inventive engineers and to improved pumps allowing access to deeper parts of the rocks. 

Queen Elizabeth I

According to Magna Britannia (Vol. 6, Devonshire, 1822) the Combmartin mines were re-opened in the reign of Queen Elizabeth I (r.1558-1603), "under the direction of Sir Bevis Bulmer, a skilful engineer much esteemed by the queen and her ministers" (Cadell. T., & Davies, W., London 1822).

The English Civil Wars (1642-1651) and Sir Thomas Bushell

Thomas Bushell (1694-1674), a celebrated mineralogist and miner of his day, and a pupil of statesman Sir Francis Bacon, governed and defended one of the last Royalist strongholds in the series of civil wars: Lundy Island, which was also under constant attack by pirates.

The so-called 'English' civil wars were part of a wider conflict also involving Wales, Scotland and Ireland. These 'Wars of the Three Kingdoms' wreaked a terrible death toll.

During 1643-4 Bushell had received the grant of Lundy from the King, together with the customs of the lead, an extension of his lease of the royal mines of Wales, and a lease of the lead mines at Combe Martin.

From Lundy, Bushell would have had access by sea to Aberystwyth, probably to the silver-lead ore mine at Llywernog. And he seems to have spent a great deal of time in Combe Martin as either the lessee or owner of its mines. 

Bushell did not surrender Lundy Island until the King had given him leave to do so — "with this caution, that you do take example from ourselves, and be not over credulous of vain promises, which hath made us great only in our sufferings, and will not discharge our debts" (Morrieson, The Coinage of Lundy).

In 1659, Thomas Bushell lobbied the English Long Parliament to re-open the Combmartin mines. Soon after the Restoration in 1660, the mines had not recovered their former credit. They do not appear to have been reopened before 1700, and then without success.

The Old Combmartin Mines in the Civil War

An attempted reopening during 1646-8 (the English Civil War) were said to have failed when the old workings were not drained. During this civil war era venture, Thomas Bushell's attempts to exploit Combe Martin silver seem to have been unsuccessful. Or were they? 

Old Combmartin Silver Coins 1647-1648

There are historic documents showing silver coins from Combmartin, minted during 1647-1648. Furthermore, in 1911, English historian and artist Frederick J. Snell B.A. recalled reading that 'a Combmartin half-crown of 1645 was sold in an auction room in London, for the sum of £5. 12s. 6d' (The Blackmore Country, pp. 272-275).

The Early Nineteenth-Century

'The mines were opened again in 1813, and continued to be worked for four years, during which time 208 tons of ore were shipped for Bristol' (ibid).

Irregular deposits, and difficulties in forecasting and prospecting for new lodes hampered by water ingress, stymied the workings up to the 19th century. 

'The quantity of silver obtained being not found sufficient to pay for the expense of working, they were given up in the month of August, 1817' (ibid).

Thereafter, British Mining Journals, and White's Gazette of 1879, record other attempts to work Combmartin mines i.e. in 1837 by a company with a capital of £30,000. After a short season of varied success they were again closed.

After 1837 the mines were worked by several different companies (White's Gazette, 1878-1879). Local Journals in 1842, reported that "a plate weighing 5lbs made of Combe Martin silver was displayed, to prove the mines were flourishing."

Mining on The Hangman Hills

In 1895, English explorer John Lloyd Warden Page, author of many guidebooks, published a piece about Combe Martin's Hangman Hills. In his guidebook The Coasts of Devon and Lundy Island, Page described mine workings he observed on the Hangman Hills. His observations are quoted below:

About three hundred feet from the summit of Great Hangman, an old mine track leads outwards and along the face past the chasm inside Blackstone Point to some adits tunnelled in the days when these hills were worked for silver, lead, iron, and copper. The first opening is a mere pit, but the second discloses the entrance to two passages or tunnels. 

The first, a steep and loose descent underground, dives into a short passage, which, turning sharp to the right, opens suddenly on the face of a precipice some seven hundred feet high. In the roof is a round hole which lets down a little light. 

The mineral was doubtless hauled up the shaft, the refuse being tipped into the sea below. The tunnel to the left passes into the hill for a distance of one hundred and fifty feet.

Beneath the track is an overgrown path running obliquely nearly to the edge of the cliff, where we come upon another tunnel, striking for about ninety feet in a direct line into the hill, and then branching to the left. Its greatest length, from the window-like opening in the cliff to the end, is one hundred and ten paces, or, say, three hundred and thirty feet. 

None of these passages are more than about three feet wide and about seven feet high. Half a mile beyond—to the westward—a zigzag path descends a sloping part of the cliff to the beach. It is now used by people to collect driftwood and laver from the rocks.

Laver, by the way, is a seaweed which is boiled and eaten very much in the same way as spinach, which in appearance it somewhat resembles. But in the old mining days this path had other uses, for about forty feet above the beach are two more caves.

They have long been abandoned, and could never, one would think, have been very productive, for no cart could by any possibility have ascended the face of the cliff, and the mineral must have been carried up in baskets.

A little further west a path, cut in the cliff, leads to another adit which has been filled up (apparently by a fall from the roof) just within the entrance. (Page, J.L.W.,1895).

A Litany of Missed Opportunities

In effect and considering the reports across our articles: Combmartin never became an established centre of mining after the seventeenth-century. Water ingress and pumping problems stymied local silver mining, but neglect and inefficiency, evident in mining journals and reports, cannot be disregarded.

Sale of the South Combmartin Mine (1880)

On Saturday May 29, 1880, a notice was posted in The Mining Journal (registered at the General Post Office as a newspaper and for transmission abroad). In Vol. 560, Issue 2336, the great Combmartin entrepreneur John Dovell announced the sale of the South Combmartin Mine.

There were three lodes in the sett which was half a mile in length. A shaft had been sunk 30 ft. on one of the lodes carrying splendid specimens of silver-lead ore.

A level can be driven which would cut all three lodes for about £500, and would leave backs from 30 to 40 fathoms [180-240 ft]; water close by for dressing. Apply to Mr. John Dovell, Combmartin, North Devon.

About Combe Martin's Ilfracombe Slate Formation

In the Combe Martin district, the Ilfracombe Slate Formation contains lead-zinc-silver deposits which were the basis of the historic mining industry here. The  Combe Martin silver mines have been closed and re-opened several times since the 13th century (Benham, McEvoy and Rollin, 2004).

Combe Martin Museum and Information Point

Combe Martin Museum and Information Point, on Cross Street, has local geological items on display, including local rocks, silver-lead and antique jewellery.

The museum also displays a fine, accurate and complete model of the Knap Down Cornish Engine House. The model includes the James Sims compound pumping engine (Beam 'bob' engine).

Archaeological Sources for Combe Martin Mining

A major source for our knowledge of Combe Martin mining is Dr Peter Claughton and colleagues, economic historians and archaeologists, specialising in the extractive industries with an emphasis on non-ferrous metal mining.

In 2000, Dr Claughton reported that -like the rest of the area and South West England as a whole- the surviving physical evidence of mining at Combe Martin is mostly from the 19th century.

Primary Sources

Much information can be gleaned from local history books, mining databases, modern sources, older texts and topographies. Our sources are listed at the bottom of this article.

Another eminent, academic source for the district's history, is John H. Moore's website including his pages on Mining in the 19th and 20th Centuries.

Information from Qualified Mining Archaeologists

This information comes from Mindat.org: at the Old Combe Martin Silver Mines there were intermittent attempts at reworking through the 18th century. The workings were re-opened in 1813, closing after four years. 

Deep workings date to 1835-1848. In 1876, that section around Harris's Shaft was reopened by Combmartin Mining Co., and worked until 1880.

According to Dr Peter Claughton: there are remains (one wall and foundations only) of a Cornish beam engine house with a remote chimney at William's Shaft, angle/balance bob pit, buttressed walls retaining spoil, blacksmith's shop and dwelling based on account house (Claughton,1991). See next paragraph:

Combe Martin Knap Down Mine

At a nearby site, the ruined engine house and chimney - minus the engine - at Knap Down on Combe Martin's Corner Lane, is associated with Cornish mining engineer and engine erector James Sims (Historic England, 2023).

Combmartin Consols Mine

Exmoor National Park Heritage Records [HER] state that at GR SS 6260 4645 - Verwill Lane EX34 0PE - are the remains of mining activity, described by Dr Peter Claughton as the Combmartin Consols or Wheal Vervale silver-lead mine. Wheal means 'workplace' and it was used as the prefix for mine names .

The remains at Verwill Lane include a mill, spoil heaps, an alleged adit and shafts. The stub of a dam also survives with a tail race leading from it (Exmoor National Park HER  MDE9012). 

Bowhay Lane Combe Martin

The Mine Tenement on Bowhay Lane was possibly known as Fayes Mine at some time in its history (Claughton, P. F., 1989). Fayes Mine went down to a depth of 32 fathoms or 58.5 metres. 

During the nineteenth-century, Mine Tenement was a hive of mining operations, with an engine house and chimney, an associated shaft, a powder house and a forge.

The Mine Forge has small stone integral gable-end stacks. The building follows a single-cell rectangular plan, nestled into the bank at the rear (north) and with its entrance positioned at the center of the south-facing front. 

This historical structure likely played a significant role in the mining operations of its time (Historic England: List Entry Number 1350387).

Challacombe Mine Sett

According to Claughton, the Lester Point adit was most probably part of silver-lead workings associated with the West Challacombe Mine sett to the east of Combe Martin, during a period of apparently unsuccessful activity at that site in the mid 19th century. 

Those workings are very much overgrown and only the spoil heap is visible. 

The northern part of the West Challacombe sett was worked for iron in 1796-1802, 1825 (Royal Stannary and British Mining Assoc.), 1855-56 (North Devon or Combmartin New Iron Mine), and again in 1867 (Hangman Hill Iron Mining Co.) (Atkinson 1997, p. 32-3).

Combe Martin Silver Mine Tenement History

Down through the centuries from 1200 AD, private prospectors and adventurers made considerable profits, and suffered disappointments.

Since 1991, workers have continued to examine, preserve and restore the  abandoned workings at Mine Tenement, EX34 0JN. 

The working tenement can be visited during visiting hours and by appointment. There are a few YouTube  videos concerning Combe Martin Silver Mines.

Master of Mines Joachim Höchstetter

In Elizabethan times, the ore was reportedly of 'remarkable purity, discovered in masses of 10 tons, 6 feet wide' (Stuckey, 1965). Combmartin Mine Tenement was reworked in 1528 under Joachim Höchstetter.

Joachim Höchstetter was a notable German mining engineer and entrepreneur during the 16th century.

He was known for his work in the mining industry, specialising in the development and management of mines in various regions, including Germany and England.

Höchstetter’s expertise in mining technology, and his innovative approaches, significantly contributed to the advancement of mining practices during his time.

The German miners were for many centuries the most skilled in Europe, and from the end of the 13th century they were called in to take part in English mining enterprises.

A 'High German' from the highlands of southern Germany, Höchstetter was Principal Surveyor and Master of the Mines Royal (of England and Ireland).

In 1528 Henry VIII commissioned Höchstetter to oversee the minerals of his realm. The Höchstetter family - international mercantile bankers and venture capitalists - were retained for the same purposes by Elizabeth I.

The old Combmartin Fayes Mine was possibly worked again from 1587-94.

Tithes Due to Churches 

In medieval England, mining prospectors were liable to pay tithes - a biblical custom - to the Church. One tenth of income compensated for the tithes of crops which would otherwise have grown on the ground taken by the mines.

A strange reason for claiming the lead-ore tithes was that 'lead was itself a titheable crop' that 'grew and renewed in the veins'. Based on both Old Testament and New Covenant, tithing in Hebrew means the practice of giving ten percent of one's annual income to the Lord. 

Discussing Water Ingress Problems

Claughton states that out of the ore mined at Combe Martin in 1292, almost 4 tons of lead were extracted (1989-1992, p.5). The accumulation of water in the lead mines interfered with work, so that in early times the Devon mines were closed down during the winter.

The flooding problem was not solved until about 1297, when pits were drained by means of 'avidods' or adits. From then on, horizontal galleries (adits) were driven from the bottom of lead pits to a level of free drainage on the surface.

Employed much earlier in tin mines, this technique and several adits can still be seen in Combe Martin.

In many mines it was also necessary to employ a number of hands in baling water out of the pits with leathern bodges or buckets. During April 1323 an average of twenty persons were so engaged at Beer Alston, and during one week the number rose to forty-eight. 

Umber Mining in Combe Martin

The working of umber (iron-oxide pigment) boomed locally during the late 1800s. Umber mining had taken place a century earlier in Berrynarbor, and the Combmartin and North Devon Umber Mines Co. resumed production in 1873.

Umber was quarried at Orchard's, Harris's, Allen's and other quarries on the southside of Combmartin. Old smelt mills were used for drying the produce in the village (Claughton, 1989-1992, p. 29).

Dark brown umber has been used in paints and dyes over millennia, right back to 1000 BC and the cave paintings in Lascaux, southern France. Renaissance shades of brown used umber.

Umber also featured in Victorian colour schemes, with rich deep shades of maroon, red, burgundy, and chestnut. 

About Manganese

Manganese - a hard, brittle, silvery metal - was mined in Combe Martin two centuries ago. It was used as a black-brown pigment in paint and, later, for dry cell batteries.

Also used by glass makers, manganese removed the greenish (iron-oxide) tint in natural glass. The manganese lends a magenta tint to glass. As the complementary colour to green, manganese effectively cancels out the green tint.

Girt Down Mine Combe Martin

The Girt Down Mine is on the southern and eastern slopes of Great Hangman, the highest sea cliff in England and Wales. Neither a central mine nor a silver mine, Girt Down was a series of prospecting plots for iron or manganese. In a leased area, the mine dates to the middle of the 19th Century.

Silverpoint

Silverpoint was used in medieval drawing and writing as one of several types of metal-point styli used by scribes, craftsmen and artists. It is a type of drawing in which an artist uses thin pieces of silver wire held in a stylus to make marks on prepared paper.

A soft silver stylus or thin metal rod inserted into a holder made an effective drawing instrument. Several celebrated artists used silverpoint styli during the Renaissance (C15 - C16).

The James Sims Compound Pumping Engine

Sims patented his compound engine in 1841, and it was by far the most widely used of the Cornish compound engines. There is much more Cornish influence in North Devon mining than is generally understood, including the miners' dialect.

The James Sims Compound Engine- What did it look like? (Article)

There are similar engine-houses in Cornwall and in Wales, and Knap Down had a self-contained beam engine. Early in 1843, the Sims combined cylinder engine, 26"/50", was erected for pumping on the main shaft (Claughton, 1989-1992, p.22). 

The Sims Compound 

According to Adam Sharpe in the Minion’s Area (1993) (quote) "the Sims Compound was a single acting Cornish engine in which the smaller steam cylinder was mounted above a larger low pressure cylinder, with the pistons having a common rod.

The engine was devised by James Sims in the 1840s. The duty was rarely more than a conventional engine, and its complexity and difficult maintenance meant that most Sims compound engines had short lives."

About Cornish Pumping Engines

Cornish engines were used for pumping water out of mines, and also for powering 'man engines' - mechanisms of reciprocating ladders or 'lifts' (up and down). There would have been stationary platforms but 'man-engine' mechanisms moved miners up and down the shafts. 

These engines were also used for winching materials into and out of the mine, and for powering on-site ore stamping machinery or crushers (stamping by pounding).

Knap Down Mine lies just under a mile northeast of St. Peter's Church. It was known as North Devon Wheal Rose in 1846. It closed in 1848, reopening in 1850 as Knap Down Consols (consolidated).

By October 23, 1852, "nothing had been heard of the Nap Down Consols (Combmartin) for eighteen months" (Mining Journal, London, 23 Oct 1852). 

Claughton states that this site was also worked by the North Devon Silver Lead Mining Company, in the Vale of Girt and Knap Down (1992, p. 30). They opened Knap Down Mine in 1859 and the Sims combined engine was restarted in 1860.

The mine probably worked an eastern extension of the Combe Martin Harris Lode, from Knap Down Shaft and Vivian's Shaft. Production records report that between 1842 and 1847 it raised 1,146 tons of lead ore.

Knap Down Engine House

According to Claughton (1992) Knap Down engine-house had a 'bob-wall', the huge mounting wall that took the weight and the force of the pivoting beam - the 'bob' - over the shaft beneath. A lean-to boiler house was on the east wall, housing high-pressure steam boilers. 

The bob-wall supported the pivot axle of the beam, or 'bob' beam, of the engine. Necessarily the strongest wall of an engine house, bob-walls were four to seven feet thick, often constructed of dressed granite.

For a pumping engine, the bob-wall was in close proximity to the shaft.  Photographs of the tall engine house at Knap Down, before it was demolished, indicate the pumping engine used two cylinders.

The smaller, higher pressure cylinder, sat on top of the larger, lower pressure cylinder (four times the size). They shared a common piston rod (Barton, D.B., 1989. p.108).

This design was supposed to control the reaction caused by higher pressures of steam, which passed from the small to the large cylinder to give a greater expansive ratio.

This configuration required a taller and more costly engine house. A taller chimney accommodated a larger draught (overcoming the resistance to the flow of air and combustion gases).

Engine-houses and bob-walls were made of masonry and timber framing, saving the costs of wrought iron. They also had to support the weight of the long pump rod, which reached deep down into the mine.

We can learn more about this from Bone and Stanier, 1998, p. 21. Knap Down engine-house was likely built in 1859, to contain the Sims compound pumping beam steam engine. 

The Combe Martin Borough Rd Smelting House 

A smelting mill house was located at the site occupied by Loverings Garage on Borough Rd. Its silver-lead smelter was operated by Combmartin and North Devon Smelting Co. Ltd, 1845-51. 

Supplies of local ore ran out, and imports rendered the business unprofitable. Thus smelting became unprofitable and the mill closed. The remains of the smelting house at this location have disappeared and no trace remains.

About Cupellation and Smelt Milling

Water-powered smelt mills were used to smelt lead and other metals. The older method of smelting lead, on wind-blown bole hills, was superseded by artificially-blown smelters.

A typical smelt mill used an ore-hearth blast furnace, and a slag-hearth furnace to reprocess stony waste material from the ore-hearth. This method recovered more lead from the waste.

The lead metal produced at Combe Martin would have undergone a cupellation process to extract its silver content. Cupellation is the oxidation of lead ore to litharge, in a shallow hearth lined with an absorbent material (Paynter, Claughton, Dunkerley, 2010).

Litharge is one of the natural mineral forms of lead(II) oxide, PbO; and a  secondary mineral which forms from the oxidation of galena ores. It has been used to manufacture Lead stabilizers, Lead glass, pottery, paints, inks, and enamels.

The silver is left unaltered whereas the litharge is absorbed by the hearth, lost as fume or skimmed off. The litharge can then be re-smelted to recover the lead (Tylecote, R.F., I990, p. 60)

Cuppelation separates 'noble' or precious metals under very high temperatures, from the base metals such as lead, copper, zinc, arsenic, present in the ore. It is not possible to remove all impurities such as lead and copper, from silver.

The Borough Rd smelting house (walls re-roofed destroying original clay tile pantile roof) had the remains of a flue, up hillside to the southwest (Claughton, 1998).

The proprietors of Combe Martin's Cranleigh House, state on their website that their building was erected on the site of the ancient Weighing House for the Combe Martin Silver Mines.

Combe Martin Lester Point Open Adit

Another local site, often overlooked, is the old adit or open entrance for silver at Lester Point on the west-projecting promontory on Combe Martin's main beach. Thought to be 19th century workings, the adit is clearly visible at low tide on the main harbour beach cliff.

Grid ref. SS5759047590, the Lester point tunnel is said to run for about 100ft before it turns off into the cliffs. Where and how much farther it actually goes, is unknown, and it would not be safe to find out.

The open adit is out on the northwest long path to the sea, and may have been part of an abandoned effort to find silver-lead.

Evidence of mineralisation, Edwards surmised this open adit was a trial. It was discovered in 1984 when storms washed away the rubble covering it (2000, p. 30).

Take good care if you decide to have a look - the Lester Point adit is a scheduled monument, the entrance apparently measures 1.5m wide and 1.7m high. The workings extend into the cliff for some 32m or about 100ft, and records suggest it goes further into a broader network.

Tudor Period

Around 1490 under Henry VII, “the Combe Martin mines were both deep and worn out”. Work at the Combe Martin mines ceased and the mines were abandoned for fifty years (Stuckey, 1965, p.6). 

Henry VIII reserved the gold and silver mines when he sold the manor and borough of Combe Martin in 1537 to Sir Richard Pollard, MP for Taunton and, later, for Devon. There is insufficient evidence from deposits or records to prove that gold was mined at Combe Martin.

Richard Pollard was elected MP for Taunton in 1536, and later for Devon in 1540 and 1542. Pollard was a prominent figure during this period, and he played a significant role in assisting Thomas Cromwell in administering the Henrician Dissolution of the Monasteries between 1536 and 1541.

One of Pollard's most notorious acts was his supervision of the destruction and pillaging of the shrine to Saint Thomas Becket, in Canterbury Cathedral during September 1538 (Scully, 2000, The Unmaking of a Saint). 

In 1587 in the reign of Elizabeth I, a rich new vein was discovered by Adrian Gilbert of Sandridge, Stoke Gabriel (MP for Bridport) and John Poppler of London, “a lapidary” or a cutter, polisher, or engraver of precious stones.

Early attempts to work the vein were unsuccessful, yet Gilbert was instrumental in operating a silver mine at Combe Martin, and he is said to have reaped £8,000 profit within a few years (History of Parliament online).

Stuckey, 1965, p.6 ; The History of Parliament research project online, 2022.

Bevis Bulmer and Joachim Höchstetter

Sir Bevis Bulmer (1536–1615), English mining engineer and prospector during the reigns of Elizabeth I and James I, “being then a great man uponn Mendipp [sic]”, rode to Combe Martin and bargained with Gilbert for a half-share in the mine, possibly called Fayes Mine at a depth of thirty-two fathoms (58.52 metres).

The Elizabethan adventurer was to have half the ore and meet all the costs of digging and refining or smelting. A smelting mill and silver refinery had been built at Combe Martin when it was worked by Joachim Höchstetter in the 1520s  (Tyson, L.O., 1996).

The mill was reportedly sited 'close to the sheltered cove' at Combe Martin, and could have been any one of the ruined smelting mills found locally.

Bulmer's venture went on for four years, and the “reasonably good yield” was worth somewhere between £6,000 and £10,000 to each partner (Stuckey, 1965, p.6. And Tyson, L.O., 1996).

Combe Martin Royal Silver for The Lord Mayor of London

The last Combe Martin silver in the 16th century was extracted in 1593, and Medley Goldsmiths of Foster Street in London made Bulmer two fine cups.

One of those cups, weighing 137 ounces, was given by Queen Elizabeth to the Lord Mayor of London at the Mansion House, with the date 1593 (Lewis, 1858).

In 1858 it was still used on the inauguration of each Lord Mayor. Stuckey says that it was presented in October 1594 to the Lord Mayor Sir Richard Martin (Goldsmith and Master of the Mint) and to the Citizens of London.

John H. Moore of Combe Martin.

The great cup or silver bowl was later melted down and made into three tankards with covers and spouts, which are still in the collection of plates at the London Mansion House (Stuckey, 1965, p.7). An engraving is included below:

When water workes in broaken wharfe
At first erected were,
And Beavis Bulmer with his art
The waters, ’gan to reare,
Disperced I in earth dyd lye
Since all beginnings old,

In place cal’d Comb wher Martin long
Had hydd me in his molde.
I did no service on the earth,
Nor no man set me free,
Till Bulmer by skill and charge
Did frame me this to be.

Here’s a breakdown of its meaning:

“When water workes in broaken wharfe / At first erected were”: This refers to the initial construction of waterworks in a broken wharf area.

“And Beavis Bulmer with his art / The waters, ’gan to reare”: Beavis (or Bevis) Bulmer, a skilled engineer, used his expertise to manage the water and raise it for mining purposes.

“Disperced I in earth dyd lye / Since all beginnings old”: The silver ore lay hidden in the earth since ancient times.

“In place cal’d Comb wher Martin long / Had hydd me in his molde”: The ore was hidden in a place called Combe, where it had been buried for a long time.

“I did no service on the earth, / Nor no man set me free”: The ore was of no use while it remained underground, and no one had extracted it.

“Till Bulmer by skill and charge / Did frame me this to be”: It was only through Bulmer’s skill and investment that the ore was mined and brought into use.

This passage highlights the ingenuity and effort required to extract valuable resources from the earth, celebrating Bulmer’s role in the process.

Conclusion

By the end of the 13th century, the English economy was heavily reliant on the circulation of a substantial quantity of silver. Despite the local silver boom, imported silver was usually a greater source of the metal in the English currency.

The history of silver mining in Combe Martin, North Devon, is a fascinating story that spans centuries from the late 13th century, when silver mining was first recorded in the area. There were boom periods in local mining between the 16th and 19th centuries.

However, Combe Martin's non-contiguous veins of lead would be considered as distinct lodes. The economic viability of mining these lodes would have depended on factors such as the concentration of lead. The costs associated with extraction, machinery and premiums were often prohibitive.

Combe Martin's mining history has been shaped by a combination of technological advancements, economic factors, and environmental concerns. Finally, the mining industry petered out in the late 19th century.

The environmental impact of historic mining, especially silver-lead mining, in Combe Martin was not inconsiderable. Mining operations started in the 13th century and were carried out sporadically until the closure of the last mine in the late 19th century. Consequently, this meant large amounts of waste and toxins.

Today, the legacy of silver mining in Combe Martin can still be seen in the abandoned mines, tunnels, and ruins that dot the landscape. The Combe Martin Silver Mines Society works tirelessly to preserve the history of the area, and to promote awareness of historic mining in the region.

¹During the 1066 Conquest which affected Combe Martin: King William I implemented a largely feudal system where land ownership was tied to service to the monarch. However, in many respects this invasion had minimal impact on the English economy or its mining operations (Dyer, Christopher, 2009).

In 12th century England, mining wasn’t a significant component of the medieval economy. Yet the 12th and 13th centuries heralded a surge in metal demand. This was largely due to substantial population growth and the construction of numerous buildings, including grand cathedrals and churches (Homer, Ronald F., 2010).

During that era in England, commercial mining was conducted for four metals: iron, tin, lead, and silver, employing a range of refining methods (Hodgett, 2006). During the reign of Edward I, which began in 1272, a new coinage was introduced which included the farthing, halfpenny, and groat. This suggests that silver mining was active during his reign (Allen, 2004).

The amount of silver mined would have varied based on many factors, including the availability of labour, technology, and the richness of the silver veins that were mined. In the early 1960s, numismatist W.J.W. Potter wrote a multipart treatise on The Silver Coinages of Richard II, Henry IV, and Henry V (The British Numismatic Society, 2023). 

Henry V reigned from 1413 until his death in 1422; his administration kept a sufficient supply of coins in circulation, implying that silver mining continued under Henry V. 

Potter (1959, 1960, 1961) argues that the experimental weight reduction of the coinage in 1412, which was continued by Henry V, was a response to the shortage of silver and the outflow of coins to the Continent (AMR Coins, 2023). 

The available information suggests that silver mining in medieval England was an ongoing process, and did not cease with the end of any individual monarch’s reign.
