Sir Bleoberis de Gannes

Next, One of the Arthurian knights of the Round Table that found the Holy Grail is Sir Bleoberis de Gannes. Sir Bleoberis was the cousin of Lancelot, the godson of King Bors, and the son of Prince Nestor of Gannes. Chretien de Troyes was the first to give him a name, possibly based on the 12-century storyteller Bleheris.

The King immediately appointed him a Knight of the Round Table after he served as the flag bearer in the Battle of Bedegraine. He participated in a number of conflicts before setting off on the quest to locate the Holy Grail, such as the conflicts with the Saxons and Agrippa and Claudas. His competence and dexterity are attested to by the fact that he was one of the few survivors at the battle of Salisbury (Mordred's rebellious war). He was the one who brutally dismembered Mordred during the battle by tying him to a horse. Along with Lancelot, he had also helped save Guenevere, and he had defended the two of them when they were accused of betraying one another.

Later, he was made Duke of Poitiers, and in his final days, the valiant knight retired to a hermitage alongside Lancelot.
