When Sir Tristram heard them say so he sent for his shield and for his spear, and lightly within a while he had overtaken them, and bade them turn and amend that they had misdone. What amends wouldst thou have? said the one knight. And therewith they took their course, and either met other so hard that Sir Tristram smote down that knight over his horse’s tail. Then the other knight dressed him to Sir Tristram, and in the same wise he served the other knight. And then they gat off their horses as well as they might, and dressed their shields and swords to do their battle to the utterance. Knights, said Sir Tristram, ye shall tell me of whence ye are, and what be your names, for such men ye might be ye should hard escape my hands; and ye might be such men of such a country that for all your evil deeds ye should pass quit. Wit thou well, sir knight, said they, we fear not to tell thee our names, for my name is Sir Agravaine, and my name is Gaheris, brethren unto the good knight Sir Gawaine, and we be nephews unto King Arthur. Well, said Sir Tristram, for King Arthur’s sake I shall let you pass as at this time. But it is shame, said Sir Tristram, that Sir Gawaine and ye be come of so great a blood that ye four brethren are so named as ye be, for ye be called the greatest destroyers and murderers of good knights that be now in this realm; for it is but as I heard say that Sir Gawaine and ye slew among you a better knight than ever ye were, that was the noble knight Sir Lamorak de Galis. An it had pleased God, said Sir Tristram, I would I had been by Sir Lamorak at his death. Then shouldst thou have gone the same way, said Sir Gaheris. Fair knight, said Sir Tristram, there must have been many more knights than ye are. And therewithal Sir Tristram departed from them toward Joyous Gard. And when he was departed they took their horses, and the one said to the other: We will overtake him and be revenged upon him in the despite of Sir Lamorak. CHAPTER LVI.
