Researchers have identified Castle Hill, an Iron Age hillfort near Beaford in North Devon, as the long-lost battlefield of the 878 Battle of Cynuit. Anglo-Saxon forces delivered a devastating defeat to an invading Viking army at the site during a pivotal moment in English history.
The clash occurred when King Alfred the Great's kingdom of Wessex stood on the brink of being overwhelmed by Scandinavian invaders. Historical accounts state that more than 800 Northmen were killed in the victory for the Anglo-Saxon army, while another ancient record places the Viking death toll at around 1,200.
Researchers also believe that a prominent mound at the site could be the burial place containing the ashes of the notorious Viking warlord Ubbe Ragnarsson.
Historian Paul Harper, author of a book detailing the findings, said researchers have searched for the location for centuries. "People have been searching for the battle site in Devon for centuries but Castle Hill has the most compelling claims and could finally solve this age-old mystery," Harper said.
"It is fascinating that this infamous Viking Ubbe probably met his demise in this quiet corner of Devon," Harper added. "What is a very remote and rural part of Britain once played centre stage to a battle that had huge ramifications for the future of the island."
Evidence matching ancient historical records
The identification of Castle Hill is based on research by historian Nick Arnold, who identified the location after examining historic records, maps, and ancient forts across Devon and Dartmoor.
The site appears to match descriptions written by Asser, the biographer of King Alfred the Great. Asser recorded that the battlefield was located in Devon, had no nearby water supply, and was particularly vulnerable from the east.
Castle Hill fits the description remarkably closely, featuring ancient earth and stone ramparts with no obvious water source within the fort itself. "This study demonstrated that Castle Hill is the only location in Devon that fits the description of a headland fort with comparatively weak defences, secure from all directions except the east," Arnold said.
A later chronicler, the 12th-century Anglo-Norman historian Geoffrey Gaimar, described the location as Penwood, a name meaning a headland next to woods. Crucially, an ancient trackway is also believed to have passed directly beside the hillfort, linking Bideford and Exeter along a route now largely followed by the A3124 road, which would have been vital for medieval armies moving through the region.
The burial mound of Ubbe Ragnarsson
A short distance from the fort lies a huge mound measuring around 39ft (12m) across and more than 8ft (2.5m) high.
Maps from the 19th century describe the mound as a tumulus, while geophysical surveys suggest it contains a pile of stones sitting on top of a rocky outcrop.
Experts believe this could be the final resting place of Ubbe Ragnarsson, who is said to have been killed at Cynuit. According to later medieval accounts, the feared Viking commander's surviving followers placed him beneath a huge burial mound after his death, naming it Ubbelawe, meaning Ubba's mound.
Geoffrey Gaimar claimed that a Viking leader named Ubbe was killed at the battle of Cynuit and was buried by followers underneath a huge mound after his death.
Ubbe Ragnarsson was a Viking warlord who led the Great Heathen Army, the huge Viking force that invaded Anglo-Saxon England in 865. According to Norse sagas, Ubbe was one of the sons of Ragnar Lothbrok, the Viking warrior whose exploits were popularised by the TV series Vikings, where Ubbe was portrayed by actor Jordan Patrick Smith.
While Ragnar himself is generally regarded as a legendary figure, Ubbe and his brothers, including Ivar the Boneless and Halfdan, are recorded as leaders of the Great Heathen Army. The Vikings had already seized much of the country when they were confronted by forces loyal to Wessex at Cynuit.
The dawn attack and defeat of the Vikings
According to the research, the Northmen may have sailed up the River Taw before targeting royal estates near Bishops Tawton, only to encounter Devon troops led by Odda, the region's chief officer.
The Anglo-Saxon forces are thought to have launched a dawn attack on the Viking camp, killing hundreds and capturing their famous raven war banner.
Weeks later, Alfred emerged from hiding in the Somerset marshes and went on to defeat the Vikings at the Battle of Edington. His victory saved Anglo-Saxon independence and helped shape the England we know today.
The discovery has been published in Paul Harper's book, Sons of Ragnar, which showcases the research by Nick Arnold.
"If the Vikings had won at the Battle of Cynuit, King Alfred would have been dead in weeks," Harper said. "There would have been no fight-back and England would have become a patchwork of Danish states. Our language, culture and history would be drastically different."
The Viking Age in Britain
The Viking Age in European history lasted from around 700 to 1100 AD. During this period, many Vikings left their homelands in Scandinavia and travelled by longboat to other countries, including Britain and Ireland.
When the people of Britain first saw the Viking longboats, they came down to the shore to welcome them. However, the Vikings fought the local people, stealing from churches and burning buildings to the ground.
The people of Britain called the invaders Danes, but they came from Norway and Sweden as well as Denmark. The name Viking comes from a language called Old Norse and means a pirate raid.
The first Viking raid recorded in the Anglo-Saxon Chronicle was around 787 AD, marking the start of a fierce struggle between the Anglo-Saxons and the Vikings.
