 The other text that seems to support the case for Arthur's historical existence is the 10th-century "Annales Cambriae", which also link Arthur with the Battle of Badon.The "Annales" date this battle to 516–518, and also mention the Battle of Camlann, in which Arthur and Medraut (Mordred) were both killed, dated to 537–539.These details have often been used to bolster confidence in the "Historia"'s account and to confirm that Arthur really did fight at Badon.
