Book X - Chapter LXXVI - How Sir Palomides changed his shield and his armour for to hurt Sir Tristram, and how Sir Launcelot did to Sir Tristram.
THEN when Sir Palomides saw that Sir Tristram was disguised, then he thought to do him a shame. So Sir Palomides rode to a knight that was sore wounded, that sat under a fair well from the field. Sir knight, said Sir Palomides, I pray you to lend me your armour and your shield, for mine is over-well known in this field, and that hath done me great damage; and ye shall have mine armour and my shield that is as sure as yours. I will well, said the knight, that ye have mine armour and my shield, if they may do you any avail. So Sir Palomides armed him hastily in that knight's armour and his shield that shone as any crystal or silver, and so he came riding into the field. And then there was neither Sir Tristram nor none of King Arthur's party that knew Sir Palomides. And right so as Sir Palomides was come into the field Sir Tristram smote down three knights, even in the sight of Sir Palomides. And then Sir Palomides rode against Sir Tristram, and either met other with great spears, that they brast to their hands. And then they dashed together with swords eagerly. Then Sir Tristram had marvel what knight he was that did battle so knightly with him. Then was Sir Tristram wroth, for he felt him passing strong, so that he deemed he might not have ado with the remnant of the knights, because of the strength of Sir Palomides. So they lashed together and gave many sad strokes together, and many knights marvelled what knight he might be that so encountered with the black knight, Sir Tristram. Full well knew La Beale Isoud that there was Sir Palomides that fought with Sir Tristram, for she espied all in her window where that she stood, as Sir Palomides changed his harness with the wounded knight. And then she began to weep so heartily for the despite of Sir Palomides that there she swooned.
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.
Then came Sir Palomides that was disguised, and smote down Sir Dinadan from his horse. Then Sir Launcelot, because Sir Dinadan had smitten him aforehand, then Sir Launcelot assailed Sir Dinadan passing sore, and Sir Dinadan defended him mightily. But well understood Sir Tristram that Sir Dinadan might not endure Sir Launcelot, wherefore Sir Tristram was sorry. Then came Sir Palomides fresh upon Sir Tristram. And when Sir Tristram saw him come, he thought to deliver him at once, because that he would help Sir Dinadan, because he stood in great peril with Sir Launcelot. Then Sir Tristram hurtled unto Sir Palomides and gave him a great buffet, and then Sir Tristram gat Sir Palomides and pulled him down underneath him. And so fell Sir Tristram with him; and Sir Tristram leapt up lightly and left Sir Palomides, and went betwixt Sir Launcelot and Dinadan, and then they began to do battle together.
Right so Sir Dinadan gat Sir Tristram's horse, and said on high that Sir Launcelot might hear it: My lord Sir Tristram, take your horse. And when Sir Launcelot heard him name Sir Tristram: O Jesu, said Launcelot, what have I done? I am dishonoured. Ah, my lord Sir Tristram, said Launcelot, why were ye disguised? ye have put yourself in great peril this day; but I pray you noble knight to pardon me, for an I had known you we had not done this battle. Sir, said Sir Tristram, this is not the first kindness ye showed me. So they were both horsed again.
Then all the people on the one side gave Sir Launcelot the honour and the degree, and on the other side all the people gave to the noble knight Sir Tristram the honour and the degree; but Launcelot said nay thereto: For I am not worthy to have this honour, for I will report me unto all knights that Sir Tristram hath been longer in the field than I, and he hath smitten down many more knights this day than I have done. And therefore I will give Sir Tristram my voice and my name, and so I pray all my lords and fellows so to do. Then there was the whole voice of dukes and earls, barons and knights, that Sir Tristram this day is proved the best knight.
