 In 945 Athelstan's successor, Edmund I, invaded Cumbria.The "Anglo-Saxon Chronicle" records the defeat of the Cumbrians and the harrying of Cumbria (referring not just to the English county of Cumberland but also all the Cumbrian lands up to Glasgow).Edmund's victory was against the last Cumbrian king, known as Dunmail (possibly Dyfnwal III of Strathclyde), and, following the defeat, the area was ceded to Malcolm I, King of Scots, although it is probable that the southernmost areas around Furness, Cartmel and Kendal remained under English control.
