How King Mark sent Sir Tristram for La Beale Isoud toward Ireland, and how by fortune he arrived into England.
Then when this was done King Mark cast always in his heart how he might destroy Sir Tristram. And then he imagined in himself to send Sir Tristram into Ireland for La Beale Isoud. For Sir Tristram had so praised her beauty and her goodness that King Mark said that he would wed her, whereupon he prayed Sir Tristram to take his way into Ireland for him on message. And all this was done to the intent to slay Sir Tristram. Notwithstanding, Sir Tristram would not refuse the message for no danger nor peril that might fall, for the pleasure of his uncle, but to go he made him ready in the most goodliest wise that might be devised. For Sir Tristram took with him the most goodliest knights that he might find in the court; and they were arrayed, after the guise that was then used, in the goodliest manner. So Sir Tristram departed and took the sea with all his fellowship. And anon, as he was in the broad sea a tempest took him and his fellowship, and drove them back into the coast of England; and there they arrived fast by Camelot, and full fain they were to take the land.
