Then said Pertolepe, the Green Knight, to the king: At a passage of the water of Mortaise there encountered Sir Beaumains with two brethren that ever for the most part kept that passage, and they were two deadly knights, and there he slew the eldest brother in the water, and smote him upon the head such a buffet that he fell down in the water, and there he was drowned, and his name was Sir Gherard le Breusse; and after he slew the other brother upon the land, his name was Sir Arnold le Breusse.
