Now shall we speak of King Arthur, that said to Sir Launcelot: Had not ye been we had not lost Sir Tristram, for he was here daily unto the time ye met with him, and in an evil time, said Arthur, ye encountered with him. My lord Arthur, said Launcelot, ye put upon me that I should be cause of his departition; God knoweth it was against my will. But when men be hot in deeds of arms oft they hurt their friends as well as their foes. And my lord, said Sir Launcelot, ye shall understand that Sir Tristram is a man that I am loath to offend, for he hath done for me more than ever I did for him as yet. But then Sir Launcelot made bring forth a book: and then Sir Launcelot said: Here we are ten knights that will swear upon a book never to rest one night where we rest another this twelvemonth until that we find Sir Tristram. And as for me, said Sir Launcelot, I promise you upon this book that an I may meet with him, either with fairness or foulness I shall bring him to this court, or else I shall die therefore. And the names of these ten knights that had undertaken this quest were these following: First was Sir Launcelot, Sir Ector de Maris, Sir Bors de Ganis, and Bleoberis, and Sir Blamore de Ganis, and Lucan the Butler, Sir Uwaine, Sir Galihud Lionel, and Galiodin.
