"Madam," said Tristram, "I will go, and for thy sake will do my best; but let me go unknown to all men; and do thou, I pray thee, keep my counsel, and help me to a disguise." So on the day of jousting came Sir Palomedes, with a black shield, and overthrew many knights. And all the people wondered at his prowess; for on the first day he put to the worse Sir Gawain, Sir Gaheris, Sir Agravaine, Sir Key, and many more from far and near. And on the morrow he was conqueror again, and overthrew the king with a hundred knights and the King of Scotland. But presently Sir Tristram rode up to the lists, having been let out at a privy postern of the castle, where none could see. La Belle Isault had dressed him in white armour and given him a white horse and shield, and so he came suddenly into the field as it had been a bright angel. As soon as Sir Palomedes saw him he ran at him with a great spear in rest, but Sir Tristram was ready, and at the first encounter hurled him to the ground. Then there arose a great cry that the knight with the black shield was overthrown. And Palomedes sorely hurt and shamed, sought out a secret way and would have left the field; but Tristram watched him, and rode after him, and bade him stay, for he had not yet done with him. Then did Sir Palomedes turn with fury, and lash at Sir Tristram with his sword; but at the first stroke Sir Tristram smote him to the earth, and cried, "Do now all my commands, or take thy death." Then he yielded to Sir Tristram's mercy, and promised to forsake La Belle Isault, and for twelve months to wear no arms or armour. And rising up, he cut his armour off him into shreds with rage and madness, and turned and left the field: and Sir Tristram also left the lists, and rode back to the castle through the postern gate. Then was Sir Tristram long cherished by the King and Queen of Ireland, and ever with La Belle Isault. But on a certain day, while he was bathing, came the queen with La Belle Isault by chance into his chamber, and saw his sword lie naked on the bed: anon she drew it from the scabbard and looked at it a long while, and both thought it a passing fair sword; but within a foot and a half of the end there was a great piece broken out, and while the queen was looking at the gap, she suddenly remembered the piece of sword-blade that was found in the brain-pan of her brother Sir Marhaus. Therewith she turned and cried, "By my faith, this is the felon knight who slew thy uncle!" And running to her chamber she sought in her casket for the piece of iron from Sir Marhaus' head and brought it back, and fitted it in Tristram's sword; and surely did it fit therein as closely as it had been but yesterday broke out.
