This request the king granted, and Sir Tristram went unto the Fair Isoud and took leave of her. And he told her all,--what he was, how he had changed his name because he would not be known, and how a lady told him that he should never be whole till he came into this country where the poison was made. She was full woe of his departing, and wept heartily.
"Madam," said Tristram, "I promise you faithfully that I shall be all the days of my life your knight."
"Grammercy," said the Fair Isoud, "and I promise you against that I shall not be married this seven years but by your assent."
Then Sir Tristram gave her a ring, and she gave him another, and therewith he departed from her, leaving her making great dole and lamentation. And he straight went unto the court among all the barons, and there he took his leave of most and least, and so departed and took the sea, and with good wind he arrived up at Tintagil in Cornwall.
HOW SIR TRISTRAM DEMANDED THE FAIR ISOUD FOR KING MARK, AND HOW SIR TRISTRAM AND ISOUD DRANK THE LOVE POTION
When there came tidings that Sir Tristram was arrived and whole of his wounds, King Mark was passing glad, and so were all the barons. And Sir Tristram lived at the court of King Mark in great joy long time, until at the last there befell a jealousy and an unkindness between them. Then King Mark cast always in his heart how he might destroy Sir Tristram.
The beauty and goodness of the Fair Isoud were so praised by Sir Tristram that King Mark said he would wed her, and prayed Sir Tristram to take his way into Ireland for him, as his messenger, to bring her to Cornwall. All this was done to the intent to slay Sir Tristram. Notwithstanding, Sir Tristram would not refuse the message for any danger or peril, and made ready to go in the goodliest wise that might be devised. He took with him the goodliest knights that he might find in the court, arrayed them after the guise that was then used, and so departed over sea with all his fellowship.
Anon as he was in the broad sea a tempest took them and drove them back into the coast of England. They came to land fast by Camelot, and there Sir Tristram set up his pavilion. Now it fell that King Anguish of Ireland was accused of slaying by treason a cousin of Sir Launcelot of the Lake, and just at this time he was come to the court at the summoning of King Arthur upon pain of forfeiture of his lands; yet ere he arrived at Camelot he wist not wherefore he was sent after. When he heard the accusation he understood full well there was no remedy but to answer it knightly, for the custom was in those days, that if any man were accused of any treason or murder, he should fight body for body or else find another knight to fight for him. Now King Anguish grew passing heavy when he heard his accusing, for the knights of King Ban's blood, as Sir Launcelot was, were as hard men to win in battle as any then living.
