About 592 Ceawlin fought a battle at Woddesbeorg (or Wodnesbeorg) also called Adam's Grave, east of Devizes in Wiltshire. There was a 'great slaughter' but nothing was said as to who he fought; Britons or Anglo-Saxons. But it was over this loss that Ceawlin was driven out of power. His nephew Ceol replaced him as king in 592. Ceawlin died in 593. At the end of his reign, the Gewisse or West Saxons held the lands of Berkshire, Wiltshire, Hampshire and much of Gloucestershire.
