Then La Beale Isoud sent unto Sir Dinas, and to Sadok, and prayed them in anywise to take King Mark, and put him in prison, unto the time that she and Sir Tristram were departed unto the realm of Logris. When Sir Dinas the Seneschal understood the treason of King Mark he promised her again, and sent her word that King Mark should be put in prison. And as they devised it so it was done. And then Sir Tristram was delivered out of prison; and anon in all the haste Queen Isoud and Sir Tristram went and took their counsel with that they would have with them when they departed. CHAPTER LII. How Sir Tristram and La Beale Isoud came unto England, and how Sir Launcelot brought them to Joyous Gard. Then La Beale Isoud and Sir Tristram took their vessel, and came by water into this land. And so they were not in this land four days but there came a cry of a jousts and tournament that King Arthur let make. When Sir Tristram heard tell of that tournament he disguised himself, and La Beale Isoud, and rode unto that tournament. And when he came there he saw many knights joust and tourney; and so Sir Tristram dressed him to the range, and to make short conclusion, he overthrew fourteen knights of the Round Table. When Sir Launcelot saw these knights thus overthrown, Sir Launcelot dressed him to Sir Tristram. That saw La Beale Isoud how Sir Launcelot was come into the field. Then La Beale Isoud sent unto Sir Launcelot a ring, and bade him wit that it was Sir Tristram de Liones. When Sir Launcelot under stood that there was Sir Tristram he was full glad, and would not joust. Then Sir Launcelot espied whither Sir Tristram yede, and after him he rode; and then either made of other great joy. And so Sir Launcelot brought Sir Tristram and La Beale Isoud unto Joyous Gard, that was his own castle, that he had won with his own hands. And there Sir Launcelot put them in to wield for their own. And wit ye well that castle was garnished and furnished for a king and a queen royal there to have sojourned. And Sir Launcelot charged all his people to honour them and love them as they would do himself.
