"Wit thou well," said he, "I fare much the worse for thee; for I know thee well, Sir Tristram de Lyonesse, thou slewest my brother, and therefore I give thee summons that I will slay thee and I may get thee at large." "Sir knight," said Sir Tristram, "I am not advised that ever I slew any brother of yours; and if ye say that I did it, I will make you amends unto my power." "I will none of your amends," said the knight, "but keep thee from me." So when he had dined, Sir Tristram asked his arms and departed; and so they rode forth on their way. And within a little while Sir Dinadan saw where came a knight riding all armed and well horsed without shield. "Sir Tristram," said Sir Dinadan, "take heed to yourself, for I undertake that yonder cometh your host that will have to do with you." "Let him come," said Sir Tristram, "I shall abide him as well as I may." Anon that knight when he came nigh Sir Tristram he cried to him, and bade him abide and keep him well. So they hurled together, but Sir Tristram smote the other knight so sore that he bare him to the ground. And that knight arose lightly, and took his horse again, and so rode fiercely to Sir Tristram, and smote him twice full hard upon the helm. "Sir knight," said Sir Tristram, "I pray you to leave off and smite me no more, for I would be loth to deal with you and I might choose, for I have your meat and your drink within my body." For all that he would not leave; and then Sir Tristram gave him such a buffet upon the helm that he tumbled upside down from his horse, that the blood brast out at the ventails of his helm; and there he lay still likely to have died. Then Sir Tristram said, "Me repenteth sore of this buffet that I smote so sore, for, as I suppose, he is dead." And so they departed and rode forth on their way. So they had not ridden but a while but they saw coming against them two full likely knights, well armed and horsed, and goodly servants about them. The one was called the king with the hundred knights, and that other was Sir Segwarides, which were renowned two noble knights. So as they came either by other, the king looked upon Sir Dinadan, which at that time had Sir Tristram's helm upon his shoulder, which helm the king had seen before with the Queen of Northwales, and that helm the Queen of Northwales had given unto la Belle Isolde, and the Queen la Belle Isolde gave it unto Sir Tristram. "Sir knight," said [the king], "where had ye that helm?" "What would ye?" said Sir Dinadan. "For I will have ado with thee," said the king, "for the love of her that owned that helm, and therefore keep you." So they departed and came together with all the mights of their horses; and there the king with the hundred knights smote Sir Dinadan, horse and all, to the earth; and then he commanded his servant, "Go and take thou his helm off, and keep it." So the varlet went to unbuckle his helm. "What helm? What wilt thou do?" said Sir Tristram; "leave that helm."
