And thereupon Isolde fell down in a sowne [swoon], and so lay a great while; and when she might speak, she said: "My lord Sir Tristram, blessed be God ye have your life, and now I am sure ye shall be discovered by this little brachet, for she will never leave you; and also I am sure that as soon as my lord King Mark shall know you, he will banish you out of the country of Cornwall, or else he will destroy you. For God's sake, mine own lord, grant King Mark his will, and then draw you unto the court of King Arthur, for there are ye beloved."
Then la Belle Isolde departed, but the brachet would not from him. And therewith came King Mark, and the brachet set upon him, and bayed at them all. And therewith Sir Andret spake and said: "Sir, this is Sir Tristram, I see by the brachet."
"Nay," said the king, "I cannot suppose that it is he."
So the king asked him upon his faith what he was, and what was his name.
"So God help," said he, "my name is Sir Tristram de Lyonesse, and now ye may do with me what ye list."
And so, by the advice of them all, Sir Tristram was banished out of the country of Cornwall for ten year, and thereupon he took his oath.
And then were many barons brought him into his ship. And when Sir Tristram was in the ship, he said thus: "Greet well King Mark and all mine enemies, and tell them I will come again when I may. And well I am rewarded for the fighting with Sir Marhaus, and delivering all the country from servage [subjection]. And well I am rewarded for the fetching and costs of la Belle Isolde out of Ireland, and the danger that I was in first and last, and by the way coming home what danger I had to bring again Queen Isolde from the castle. And well I am rewarded when I fought with Sir Bleoberis for Sir Segwarides' wife. And well am I rewarded when I fought with Sir Blamor de Ganis for King Anguish, father unto la Belle Isolde. And well am I rewarded when I smote down the good knight Sir Lamorak de Galis at King Mark's request. And well am I rewarded when I fought with the king with the hundred knights, and the King of Northgalis, and both these would have put his land in servage, and by me they were put to a rebuke. And well am I rewarded for the slaying of Tauleas the mighty giant, and many moe deeds have I done for him, and now have I my guerdon. And tell the King Mark that many noble knights of the Round Table have spared the barons of this country for my sake. Also I am not well rewarded when I fought with the good knight Sir Palamides, and rescued Queen Isolde from him. And at that time King Mark said before all his barons I should have been better rewarded." And therewith he took the sea.
[In those days was holden a great tournament at the Castle of Maidens, and thereto came Sir Tristram, for King Arthur was there, with his knights, and a goodly press of other kings, lords and ladies. And Sir Tristram let make him a black shield, and therewith was he ever to be known in the midst of the knights. And Sir Tristram overthrew eleven knights of Sir Launcelot's kin in one day, and jousted with King Arthur and with Sir Launcelot in such wise that all men wondered. And at the last Sir Tristram was sore wounded, and rode away into a forest. But Sir Launcelot held away the stour [fight] like as a man enraged that took no heed to himself.] And because Sir Launcelot was the last in the field the prize was given him. But Sir Launcelot would neither for king, queen, nor knight have the prize; but when the cry was cried through the field, "Sir Launcelot. Sir Launcelot, hath won the field this day!" Sir Launcelot let make another cry contrary to that cry: "Sir Tristram hath won the field, for he began first, and last he hath endured, and so hath he done the first day, the second, and the third day."
[And so King Arthur and Sir Launcelot and more knights rode forth for to find Sir Tristram. And after many adventures it happened that Sir Launcelot passed by the tomb of Sir Lanceor (him that was slain by Balin) and his lady Colombe. And by that same tomb came Sir Tristram: and neither knew the other, but Sir Tristram weened it to have been Sir Palamides. Then they two fought, and each wounded other wonderly sore, that the blood ran out upon the grass. And thus they fought the space of four hours. And at the last either knew other. Then cried Sir Launcelot,] "Oh, what adventure is befallen me!"
