Bedivere is one of Arthur's loyal allies and helps Arthur and Kay fight the Giant of Mont Saint-Michel, and joins Arthur in his war against Emperor Lucius of Rome, in which he dies fighting.[9] In the English Alliterative Morte Arthure, he and Kay are mortally wounded while heroically fighting against the Romans in the Battle of Sessye.[10][11] In Malory's version and the Stanzaic Morte Arthur, Bedivere and Arthur are among the few survivors of the Battle of Camlann (or of Salisbury). After the battle, at the request of the mortally wounded king, Bedivere casts away the sword Excalibur that Arthur had received from the Lady of the Lake. However, he does this only after twice thinking the sword too valuable to Britain to throw into the water.[14] When he reports that nothing in particular happened, King Arthur admonishes him, for Arthur knows that the mystical sword would create some supernatural event. Finally, Bedivere casts the sword into the water, at which a hand arises and catches the sword mid-air, then sinks into the waters, and Arthur is thus assured that the sword has been returned. In Malory's telling, this act summons Morgan and Nimue, who take the king to Avalon. Upon the presumed death of Arthur, Bedivere enters a hermitage led by the Mordred-ousted Archbishop of Canterbury, where he spends the remainder of his life. There he will be joined by Lancelot and some of his kindred knights, who will resort to it in their own penitence. - Source: Wikipedia
