"Sir," saith one of the old knights to Perceval, "Look! here is the Lord of the Moors coming, that hath reft your mother of her land and slain her men. Of him will it be good to take vengeance. See, how boldly he cometh." Perceval looketh on him as he that loveth him not, and cometh toward him as hard as his horse may carry him, and smiteth him right through the breast so strongly that he beareth to the ground him and his horse together all in a heap. He alighteth to the ground and draweth his sword. "How?" saith the Lord of the Moors, "Would you then slay me and put me in worse plight than I am?" "By my head," saith Perceval, "No, nor so swiftly, but I will slay you enough, betimes!" "So it seemeth you," saith the Lord of the Moors, "But it shall not be yet!" He leapeth up on his feet and runneth on Perceval, sword drawn, as one that fain would harm him if he might. But Perceval defendeth himself as good knight should, and giveth such a buffet at the outset as smiteth off his arm together with his sword. The knights that came after fled back all discomfited when they saw their lord wounded. And Perceval made lift him on a horse and carry him to the castle and presenteth him to his mother. "Lady," saith he, "See here the Lord of the Moors! Well might you expect him eftsoons, sith that you were to have yielded him up your castle the day after to-morrow!" XXXI. "Lady," saith the Lord of the Moors, "Your son hath wounded me and taken my knights and myself likewise. I will yield you up your castle albeit I hold it mine as of right, on condition you cry me quit." "And who shall repay her," saith Perceval, "for the shame that you have done her, for her knights that you have slain, whereof never had you pity? Now, so help me God, if she have mercy or pity upon you, never hereafter will I trouble to come to her aid how sore soever may be her need. Such pity and none other as you have had for her and my sister will I have for you. Our Lord God commanded in both the Old Law and the New, that justice should be done upon man-slayers and traitors, and justice will I do upon you that His commandment be not transgressed." He hath a great vat made ready in the midst of the court, and maketh the eleven knights be brought. H e maketh their heads be stricken off into the vat and bleed therein as much blood as might come from them, and then made the heads and the bodies be drawn forth so that nought was there but blood in the vat. After that, he made disarm the Lord of the Moors and be brought before the vat wherein was great abundance of blood. He made bind his feet and his hands right strait, and after that saith: "Never might you be satisfied of the blood of the knights of my lady mother, now will I satisfy you of the blood of your own knights!"
