Abstract:

This original study examines the Battle of Cynwit /sɪn.wɪt/ in early 878 AD, a pivotal conflict in Devonshire, England, between Danish Vikings and a victorious Wessex fyrd militia. The battle is not widely recognised, yet it was momentous for several reasons.

Led by an unnamed konungr or king, possibly called Ubba or Hubba—Old Norse: Ubbi; died 878—a large Danish Viking force laid siege to the hillfort of Cynwit, proposed among other candidates to be at "Countisbury Castle". Also known as 'Wind Hill', the British Iron Age hillfort stands above Lynmouth in Exmoor National Park.

Over time, particularly in the late 9th century, some Vikings shifted their focus from raiding to settlement. They established strongholds and territories, most notably in the Danelaw, which included parts of Northumbria, East Anglia and Mercia, in Early Medieval England.

At grid reference SS 7386 4953 to SS 7410 4922, Wind Hill Iron Age univallate promontory fort (c. 800 BC to AD 43) lies a few miles east of Combe Martin in the South West region of England.

Chronicles state that under Ealdorman (Earl) Odda or Oddune, the Wessex king's thegns and their followers launched a surprise dawn ambush, decisively routing the Viking siege force. The Vikings were caught off-guard, and Hubba's Raven war-flag was captured.

The Anglo-Saxon Chronicle (ASC) reports that 840 out of 1,200 Vikings were killed, including Hubba and 40 elite housecarls. The ninth-century chronicler Asser notes in his Life of Alfred that the West Saxons "slew most of the Danes, together with their king."

In spite of this discrepancy, it appears the Danish forces at Cynwit were heavily defeated, and practically wiped out.

Odda's victory was crucial in preventing the total subjugation of Wessex, the last remaining early-English kingdom. The Battle of Cynwit should not be viewed as an isolated event. The conflicts and Viking defeats that followed in 878 AD were crucial for the independence of early English society.

Anglo-Saxony ('Englisc') faced the overwhelming threat of Viking invasions in a politically fragmented region. The Battle of Cynwit was a pivotal victory for Alfred the Great and the Kingdom of Wessex, strengthening resistance against Viking invasions and influencing English history and identity.

The specifics of the Vikings' movements are less documented, while their raids on Wessex reflect the turbulent period of Viking invasions in England.

Although contemporary sources provide context, they do not pinpoint the battle of Cynwit's exact location. It is often regarded as a turning point in the struggle for English sovereignty and the making of England.

The 9th century was a transformative period for Wessex, particularly under the leadership of King Alfred the Great (849–99; r. 871–99). However, it is necessary to challenge the single narrative and to acknowledge other perspectives.

Alfred’s reign amid Viking raids is marked by several key achievements that helped unify the Englisc and establish Wessex as the dominant English kingdom.
