Now pass we our matter, and leave we Sir Gawaine, and speak of King Arthur, that on a day said unto King Mark: Sir, I pray you give me a gift that I shall ask you. Sir, said King Mark, I will give you whatsomever ye desire an it be in my power. Sir, gramercy, said Arthur. This I will ask you, that ye will be good lord unto Sir Tristram, for he is a man of great honour; and that ye will take him with you into Cornwall, and let him see his friends, and there cherish him for my sake. Sir, said King Mark, I promise you by the faith of my body, and by the faith that I owe to God and to you, I shall worship him for your sake in all that I can or may. Sir, said Arthur, and I will forgive you all the evil will that ever I ought you, an so be that you swear that upon a book before me. With a good will, said King Mark; and so he there sware upon a book afore him and all his knights, and therewith King Mark and Sir Tristram took either other by the hands hard knit together. But for all this King Mark thought falsely, as it proved after, for he put Sir Tristram in prison, and cowardly would have slain him. Then soon after King Mark took his leave to ride into Cornwall, and Sir Tristram made him ready to ride with him, whereof the most part of the Round Table were wroth and heavy, and in especial Sir Launcelot, and Sir Lamorak, and Sir Dinadan, were wroth out of measure. For well they wist King Mark would slay or destroy Sir Tristram. Alas, said Dinadan, that my lord, Sir Tristram, shall depart. And Sir Tristram took such sorrow that he was amazed like a fool. Alas, said Sir Launcelot unto King Arthur, what have ye done, for ye shall lose the most man of worship that ever came into your court. It was his own desire, said Arthur, and therefore I might not do withal, for I have done all that I can and made them at accord. Accord, said Sir Launcelot, fie upon that accord, for ye shall hear that he shall slay Sir Tristram, or put him in a prison, for he is the most coward and the villainest king and knight that is now living.
