The Battle of Brunanburh was a West Saxon victory in 937 by the army of Athelstan, King of England, and his brother, Edmund, over the combined armies of Olaf III Guthfrithson, Norse King of Dublin, Constantine II, King of Scots, and Owen I, King of Strathclyde (mention is also made in some sources of Irish, Welsh and Cornish mercenaries).
Athelstan had invaded the Kingdom of Strathclyde a few years previously (roughly 933-934). This provoked much anger across the British Isles among rulers no doubt fearing for their own positions.
The Anglo-Saxon Chronicle records the event as follows:
The battle is considered one of the bloodiest of the period. Five English kings and seven earls were killed in the battle. Two of Athelstan's cousins Alfric and Athelwin and a prominent Saxon bishop were also killed. Some sources claime that at one point the West Saxons deployed a cavalry charge, contradicting popular belief that the early English fought in infantry-based armies. Cavalry were a relatively insignificant part of the Saxon force and were likely mercenaries from any number of other kingdoms. However, the Anglo-Saxon text of the chronicle makes no such mention: Burton Raffel's translation of the poem, for instance, is misleading. His rendering "All the battle / Became the Wessex cavalry endlessly / Hunting a broken enemy" mistranslates the Anglo-Saxon 'eorodcistum,' which means 'troop' or 'company.'
This poorly recalled battle is actually one of the most important in British history since Athelstan's crushing defeat of the combined Norse-Celtic force facing him irrevocably confirmed England as an Anglo-Saxon kingdom, forcing the Celtic kingdoms to consolidate in the positions they occupy today.
The Battle of Brunanburh still has a great deal of influence in the Wiltshire town of Malmesbury, 200 miles south of any probable site. The townsfolk of Malmesbury fought for King Athelstan, and he granted them 600 hides of land and gave them all freemen status. This status and the organisation formed then exists today, as the Warden and Freemen of Malmesbury, and Athelstan is remembered in their ceremonies. When Athelstan died, his body was transported from Gloucester to Malmesbury for burial.
English poet Alfred Lord Tennyson translated the poem from the Anglo-Saxon Chronicle in 1880, publishing it as part of his Ballads and Other Poems. Tennyson's son Hallam Tennyson published a prose translation of the poem. The Argentine writer Jorge Luis Borges wrote various poems about or mentioning the Saxons and their victory at Brunanburh.
