Then upon a day King Anguish asked Sir Tristram why he asked not his boon, for whatsoever he had promised him he should have it without fail.
"Sir," said Sir Tristram, "now is it time, this is all that I will desire, that ye will give me la Belle Isolde, your daughter, not for myself, but for mine uncle King Mark, that shall have her to wife, for so have I promised him."
"Alas," said the king, "I had liever than all the land that I have ye would wed her yourself."
"Sir, and I did, then were I shamed for ever in this world, and false of my promise. Therefore," said Sir Tristram, "I pray you hold your promise that ye promised me, for this is my desire, that ye will give me la Belle Isolde to go with me into Cornwall, for to be wedded to King Mark mine uncle."
"As for that," said King Anguish, "ye shall have her with you, to do with her what it please you, that is for to say if that ye list to wed her yourself, that is to me lievest, and if ye will give her unto King Mark your uncle, that is in your choice."
So to make a short conclusion, la Belle Isolde was made ready to go with Sir Tristram, and dame Bragwaine went with her for her chief gentlewoman, with many other.
And anon they were richly wedded with great nobleness. But ever Sir Tristram and la Belle Isolde loved ever together.
Then was there great jousts and great tourneying, and many lords and ladies were at that feast, and Sir Tristram was most praised of all other.
[Then, as time passed by, Sir Tristram grieved sorely in his heart that la Belle Isolde was wedded to King Mark, till that he became as a wood man, and mounted his horse and rode forth into the forest away from Tintagil. So Sir Palamides sent a damsel to inquire after Sir Tristram.]
