SO on the morn Sir Launcelot departed, and Sir Tristram was ready, and La Beale Isoud with Sir Palomides and Sir Gareth. And so they rode all in green full freshly beseen unto the forest. And Sir Tristram left Sir Dinadan sleeping in his bed. And so as they rode it happed the king and Launcelot stood in a window, and saw Sir Tristram ride and Isoud. Sir, said Launcelot, yonder rideth the fairest lady of the world except your queen, Dame Guenever. Who is that? said Sir Arthur. Sir, said he, it is Queen Isoud that, out-taken my lady your queen, she is makeless. Take your horse, said Arthur, and array you at all rights as I will do, and I promise you, said the king, I will see her. Then anon they were armed and horsed, and either took a spear and rode unto the forest. Sir, said Launcelot, it is not good that ye go too nigh them, for wit ye well there are two as good knights as now are living, and therefore, sir, I pray you be not too hasty. For peradventure there will be some knights be displeased an we come suddenly upon them. As for that, said Arthur, I will see her, for I take no force whom I grieve. Sir, said Launcelot, ye put yourself in great jeopardy. As for that, said the king, we will take the adventure. Right so anon the king rode even to her, and saluted her, and said: God you save. Sir, said she, ye are welcome. Then the king beheld her, and liked her wonderly well.

With that came Sir Palomides unto Arthur, and said: Uncourteous knight, what seekest thou here? thou art uncourteous to come upon a lady thus suddenly, therefore withdraw thee. Sir Arthur took none heed of Sir Palomides' words, but ever he looked still upon Queen Isoud Then was Sir Palomides wroth, and therewith he took a spear, and came hurtling upon King Arthur, and smote him down with a spear. When Sir Launcelot saw that despite of Sir Palomides, he said to himself: I am loath to have ado with yonder knight, and not for his own sake but for Sir Tristram. And one thing I am sure of, if I smite down Sir Palomides I must have ado with Sir Tristram, and that were overmuch for me to match them both, for they are two noble knights; notwithstanding, whether I live or I die, needs must I revenge my lord, and so will I, whatsomever befall of me. And therewith Sir Launcelot cried to Sir Palomides: Keep thee from me. And then Sir Launcelot and Sir Palomides rushed together with two spears strongly, but Sir Launcelot smote Sir Palomides so hard that he went quite out of his saddle, and had a great fall. When Sir Tristram saw Sir Palomides have that fall, he said to Sir Launcelot: Sir knight, keep thee, for I must joust with thee. As for to joust with me, said Sir Launcelot, I will not fail you, for no dread I have of you; but I am loath to have ado with you an I might choose, for I will that ye wit that I must revenge my special lord that was unhorsed unwarly and unknightly. And therefore, though I revenged that fall, take ye no displeasure therein, for he is to me such a friend that I may not see him shamed.

Anon Sir Tristram understood by his person and by his knightly words that it was Sir Launcelot du Lake, and verily Sir Tristram deemed that it was King Arthur, he that Sir Palomides had smitten down. And then Sir Tristram put his spear from him, and put Sir Palomides again on horseback, and Sir Launcelot put King Arthur on horseback and so departed. So God me help, said Sir Tristram unto Palomides, ye did not worshipfully when ye smote down that knight so suddenly as ye did. And wit ye well ye did yourself great shame, for the knights came hither of their gentleness to see a fair lady; and that is every good knight's part, to behold a fair lady; and ye had not ado to play such masteries afore my lady. Wit thou well it will turn to anger, for he that ye smote down was King Arthur, and that other was the good knight Sir Launcelot. But I shall not forget the words of Sir Launcelot when that he called him a man of great worship, thereby I wist that it was King Arthur. And as for Sir Launcelot, an there had been five hundred knights in the meadow, he would not have refused them, and yet he said he would refuse me. By that again I wist that it was Sir Launcelot, for ever he forbeareth me in every place, and showeth me great kindness; and of all knights, I out-take none, say what men will say, he beareth the flower of all chivalry, say it him whosomever will. An he be well angered, and that him list to do his utterance without any favour, I know him not alive but Sir Launcelot is over hard for him, be it on horseback or on foot. I may never believe, said Palomides, that King Arthur will ride so privily as a poor errant knight. Ah, said Sir Tristram, ye know not my lord Arthur, for all knights may learn to be a knight of him. And therefore ye may be sorry, said Sir Tristram, of your unkindly deeds to so noble a king. And a thing that is done may not be undone, said Palomides. Then Sir Tristram sent Queen Isoud unto her lodging in the priory, there to behold all the tournament.
