Then came in Sir Launcelot with the knights of Orkney. And when the other party had espied Sir Launcelot, they cried: Return, return, here cometh Sir Launcelot du Lake. So there came knights and said: Sir Launcelot, ye must needs fight with yonder knight in the black harness, that was Sir Tristram, for he hath almost overcome that good knight that fighteth with him with the silver shield, that was Sir Palomides. Then Sir Launcelot rode betwixt Sir Tristram and Sir Palomides, and Sir Launcelot said to Palomides: Sir knight, let me have the battle, for ye have need to be reposed. Sir Palomides knew Sir Launcelot well, and so did Sir Tristram, but because Sir Launcelot was far hardier knight than himself therefore he was glad, and suffered Sir Launcelot to fight with Sir Tristram. For well wist he that Sir Launcelot knew not Sir Tristram, and there he hoped that Sir Launcelot should beat or shame Sir Tristram, whereof Sir Palomides was full fain. And so Sir Launcelot gave Sir Tristram many sad strokes, but Sir Launcelot knew not Sir Tristram, but Sir Tristram knew well Sir Launcelot. And thus they fought long together, that La Beale Isoud was well-nigh out of her mind for sorrow. Then Sir Dinadan told Sir Gareth how that knight in the black harness was Sir Tristram: And this is Launcelot that fighteth with him, that must needs have the better of him, for Sir Tristram hath had too much travail this day. Then let us smite him down, said Sir Gareth. So it is better that we do, said Sir Dinadan, than Sir Tristram be shamed, for yonder hoveth the strong knight with the silver shield to fall upon Sir Tristram if need be. Then forthwithal Gareth rushed upon Sir Launcelot, and gave him a great stroke upon his helm so hard that he was astonied. And then came Sir Dinadan with a spear, and he smote Sir Launcelot such a buffet that horse and all fell to the earth. O Jesu, said Sir Tristram to Sir Gareth and Sir Dinadan, fie for shame, why did ye smite down so good a knight as he is, and namely when I had ado with him? now ye do yourself great shame, and him no disworship; for I held him reasonable hot, though ye had not holpen me.
