CHAPTER L.How by treason Sir Tristram was brought to a tournament for.
to have been slain, and how he was put in prison.
NOW turn we from this matter, and speak we of Sir Tristram, of whom this book is principally of, and leave we the king and the queen, Sir Launcelot, and Sir Lamorak, and here beginneth the treason of King Mark, that he ordained against Sir Tristram.

There was cried by the coasts of Cornwall a great tournament and jousts, and all was done by Sir Galahalt the haut prince and King Bagdemagus, to the intent to slay Launcelot, or else utterly destroy him and shame him, because Sir Launcelot had always the higher degree, therefore this prince and this king made this jousts against Sir Launcelot.

And thus their counsel was discovered unto King Mark, whereof he was full glad.
Then King Mark bethought him that he would have Sir Tristram unto that tournament disguised that no man should know him, to that intent that the haut prince should ween that Sir Tristram were Sir Launcelot.

So at these jousts came in Sir Tristram.

And at that time Sir Launcelot was not there, but when they saw a knight disguised do such deeds of arms, they weened it had been Sir Launcelot.
