The medieval texts employ a plethora of alternative names for the site of the battle, which historians have attempted to link to known places. The earliest relevant document is the “"Battle of Brunanburh"” poem in the Anglo-Saxon Chronicle (version A), written within two decades of the battle, which names the battlefield location as “"ymbe Brunanburh"” (around Brunanburh) and says that the fleeing Norsemen set out upon “"Dingesmere"” for Dublin. Many other medieval sources contain variations on the name Brunanburh, such as "Brune", "Brunandune", "Et Brunnanwerc", "Bruneford", "Cad Dybrunawc" "Duinbrunde" and "Brounnyngfelde".
