Le Morte D'Arthur

Now leave we of Sir Lamorak, and speak of Sir Gawaine's brethren, and specially of Sir Agravaine and Sir Mordred. As they rode on their adventures they met with a knight fleeing, sore wounded; and they asked him what tidings. Fair knights, said he, here cometh a knight after me that will slay me. With that came Sir Dinadan riding to them by adventure, but he would promise them no help. But Sir Agravaine and Sir Mordred promised him to rescue him. Therewithal came that knight straight unto them, and anon he proffered to joust. That saw Sir Mordred and rode to him, but he struck Mordred over his horse's tail. That saw Sir Agravaine, and straight he rode toward that knight, and right so as he served Mordred so he served Agravaine, and said to them: Sirs, wit ye well both that I am Breuse Saunce Pité, that hath done this to you. And yet he rode over Agravaine five or six times. When Dinadan saw this, he must needs joust with him for shame. And so Dinadan and he encountered together, that with pure strength Sir Dinadan smote him over his horse's tail. Then he took his horse and fled, for he was on foot one of the valiantest knights in Arthur's days, and a great destroyer of all good knights.

Then rode Sir Dinadan unto Sir Mordred and unto Sir Agravaine. Sir knight, said they all, well have ye done, and well have ye revenged us, wherefore we pray you tell us your name. Fair sirs, ye ought to know my name, the which is called Sir Dinadan. When they understood that it was Dinadan they were more wroth than they were before, for they hated him out of measure because of Sir Lamorak. For Dinadan had such a custom that he loved all good knights that were valiant, and he hated all those that were destroyers of good knights. And there were none that hated Dinadan but those that ever were called murderers. Then spake the hurt knight that Breuse Saunce Pité had chased, his name was Dalan, and said: If thou be Dinadan thou slewest my father. It may well be so, said Dinadan, but then it was in my defence and at his request. By my head, said Dalan, thou shalt die therefore, and therewith he dressed his spear and his shield. And to make the shorter tale, Sir Dinadan smote him down off his horse, that his neck was nigh broken. And in the same wise he smote Sir Mordred and Sir Agravaine. And after, in the quest of the Sangreal, cowardly and feloniously they slew Dinadan, the which was great damage, for he was a great bourder and a passing good knight.
