“He speaketh falsely,” said the lady, “for he is jealous of me without cause, as I shall answer before Heaven; but as thou art named the most worshipful knight in the world, I pray thee of thy true knighthood to save me, for he is without mercy.”

“Be of good cheer,” said Sir Lancelot; “it shall not lie within his power to harm thee.”

“Sir,” said the knight, “I will be ruled as ye will have me.”

So Sir Lancelot rode between the knight and the lady.  And when they had ridden awhile, the knight cried out suddenly to Sir Lancelot to turn and see what men they were who came riding after them; and while Sir Lancelot, thinking not of treason, turned to look, the knight, with one great stroke, smote off the lady’s head.

Then was Sir Lancelot passing wroth, and cried, “Thou traitor!  Thou hast shamed me for ever!” and, alighting from his horse, he drew his sword to have slain him instantly; but the knight fell on the ground and clasped Sir Lancelot’s knees, and cried out for mercy.  “Thou shameful knight,” answered Lancelot, “thou mayest have no mercy, for thou showedst none, therefore arise and fight with me.”

“Nay,” said the knight, “I will not rise till thou dost grant me mercy.”

“Now will I deal fairly by thee,” said Sir Lancelot; “I will unarm me to my shirt, and have my sword only in my hand, and if thou canst slay me thou shall be quit for ever.”

“That will I never do,” said the knight.

“Then,” answered Sir Lancelot, “take this lady and the head, and bear it with thee, and swear to me upon thy sword never to rest until thou comest to Queen Guinevere.”

“That will I do,” said he.

“Now,” said Sir Lancelot, “tell me thy name.”

“It is Pedivere,” answered the knight.

“In a shameful hour wert thou born,” said Sir Lancelot.

So Sir Pedivere departed, bearing with him the dead lady and her head.  And when he came to Winchester, where the Queen was with King Arthur, he told them all the truth; and afterwards did great and heavy penance many years, and became an holy hermit.

“So, two days before the Feast of Pentecost, Sir Lancelot returned to the court, and King Arthur was full glad of his coming.  And when Sir Gawain, Sir Ewaine, Sir Sagramour, and Sir Ector, saw him in Sir Key’s armour, they knew well it was he who had smitten them all down with one spear.  Anon, came all the knights Sir Turquine had taken prisoners, and gave worship and honour to Sir Lancelot.  Then Sir Key told the King how Sir Lancelot had rescued him when he was in near danger of his death; “and,” said Sir Key, “he made the knights yield, not to himself, but me.  And by Heaven! because Sir Lancelot took my armour and left me his, I rode in peace, and no man would have aught to do with me.”  Then came the knights who fought with Sir Lancelot at the long bridge and yielded themselves also to Sir Key, but he said nay, he had not fought with them.  “It is Sir Lancelot,” said he, “that overcame ye.”  Next came Sir Meliot de Logres, and told King Arthur how Sir Lancelot had saved him from death.
