A Scottish knight in The Awntyrs of Arthur whose lands were annexed by Arthur and given to Gawaine. Angry, Galleron appeared at Arthur’s feast at Rondoles Hall and challenged any of Arthur’s knights to a duel. Gawaine fought with him at Plumpton. Galleron proved strong and seemed to be winning at the beginning. When Gawaine made a comeback, Galleron killed Gawaine’s horse, Grissel. They fought for hours longer, and both were wounded severely but neither proved the victor. Finally, Galleron yielded to Gawaine and ended the combat. For his bravery, Gawaine bestowed upon Galleron all the lands that Arthur had annexed. Galleron was then made a Knight of the Round Table.
