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. And in especial King Mark said it was Sir Launcelot plainly. Then they set upon him, both King Bagdemagus, and the haut prince, and their knights, that it was wonder that ever Sir Tristram might endure that pain. Notwithstanding for all the pain that he had, Sir Tristram won the degree at that tournament, and there he hurt many knights and bruised them, and they hurt him and bruised him wonderly sore. So when the jousts were all done they knew well that it was Sir Tristram de Liones; and all that were on King Mark’s party were glad that Sir Tristram was hurt, and the remnant were sorry of his hurt; for Sir Tristram was not so behated as was Sir Launcelot within the realm of England. Then came King Mark unto Sir Tristram and said: Fair nephew, I am sorry of your hurts. Gramercy my lord, said Sir Tristram. Then King Mark made Sir Tristram to be put in an horse bier in great sign of love, and said: Fair cousin, I shall be your leech myself. And so he rode forth with Sir Tristram, and brought him to a castle by daylight. And then King Mark made Sir Tristram to eat. And then after he gave him a drink, the which as soon as he had drunk he fell asleep. And when it was night he made him to be carried to another castle, and there he put him in a strong prison, and there he ordained a man and a woman to give him his meat and drink. So there he was a great while.
