Mordred laced on his own, mounted his horse, took up his lance, spurred toward the first knight, and struck him so violently that he knocked him over the horse's rump to the ground. The point of the knight's helmet was stuck in the ground, and the knight was wounded in his fall; he fainted from the pain, for he was badly wounded, his collarbone nearly broken. Mordred took the horse by the reins and brought it to Lancelot, saying, "Here, my lord, in payment for yours that they took last evening."

Then the other knight came spurring with all the speed he could get from his horse; he struck Mordred on the top edge of his shield, so that his lance flew to pieces. But Mordred aimed low, just above the saddlebow, and struck him so violently that he pierced both shield and hauberk, thrust the iron head of his lance into the knight's body, and knocked him to the ground so badly wounded that he was beyond any doctor's help.
