And when Sir Launcelot had espied him what he had done, he said, and called him, Traitor, thou hast shamed me for ever. And suddenly Sir Launcelot alighted off his horse, and pulled out his sword to slay him, and therewithal he fell flat to the earth, and gripped Sir Launcelot by the thighs, and cried mercy. Fie on thee, said Sir Launcelot, thou shameful knight, thou mayest have no mercy, and therefore arise and fight with me. Nay, said the knight, I will never arise till ye grant me mercy. Now will I proffer thee fair, said Launcelot, I will unarm me unto my shirt, and I will have nothing upon me but my shirt, and my sword and my hand. And if thou canst slay me, quit be thou for ever. Nay, sir, said Pedivere, that will I never. Well, said Sir Launcelot, take this lady and the head, and bear it upon thee, and here shalt thou swear upon my sword, to bear it always upon thy back, and never to rest till thou come to Queen Guenever. Sir, said he, that will I do, by the faith of my body. Now, said Launcelot, tell me what is your name? Sir, my name is Pedivere. In a shameful hour wert thou born, said Launcelot.
