Then was King Arthur wroth out of measure, and so were all the other knights.

But when Sir Tristram knew all the matter he made great dole and sorrow out of measure, and wept for sorrow for the loss of the noble knights, Sir Bersules and of Sir Amant.
When Sir Launcelot espied Sir Tristram weep he went hastily to King Arthur, and said: Sir, I pray you give me leave to return again to yonder false king and knight.

I pray you, said King Arthur, fetch him again, but I would not that ye slew him, for my worship.

Then Sir Launcelot armed him in all haste, and mounted upon a great horse, and took a spear in his hand and rode after King Mark.

And from thence a three mile English Sir Launcelot over took him, and bade him: Turn recreant king and knight, for whether thou wilt or not thou shalt go with me to King Arthur's court.
