Old English poem of 73 lines included in the Anglo-Saxon Chronicle under the year 937. It relates the victory of the Saxon king Athelstan over the allied Norse, Scots, and Strathclyde Briton invaders under the leadership of Olaf Guthfrithson, king of Dublin and claimant to the throne of York. The poem is probably a panegyric composed for Athelstan to celebrate his victory. It counts the dead kings and earls on the battlefield and pictures the Norsemen slinking back to Dublin in their ships while their dead sons are being devoured by ravens and wolves. The poem claims that this was the greatest battle ever fought in England.
