When the King had taken his throne, the seneschal arose to prove by witness and by arms that he had slain the dragon and that so Iseult was won. Then Iseult bowed to her father and said: "King, I have here a man who challenges your seneschal for lies and felony. Promise that you will pardon this man all his past deeds, who stands to prove that he and none other slew the dragon, and grant him forgiveness and your peace."
The King said, "I grant it." But Iseult said, "Father, first give me the kiss of peace and forgiveness, as a sign that you will give him the same."
Then she found Tristan and led him before the Barony. And as he came the hundred knights rose all together, and crossed their arms upon their breasts and bowed, so the Irish knew that he was their lord.
But among the Irish many knew him again and cried, "Tristan of Lyonesse that slew the Morholt!" They drew their swords and clamoured for death. But Iseult cried: "King, kiss this man upon the lips as your oath was," and the King kissed him, and the clamour fell.
Then Tristan showed the dragon's tongue and offered the seneschal battle, but the seneschal looked at his face and dared not.
Then Tristan said: "My lords, you have said it, and it is truth: I killed the Morholt. But I crossed the sea to offer you a good blood-fine, to ransom that deed and get me quit of it.
"I put my body in peril of death and rid you of the beast and have so conquered Iseult the Fair, and having conquered her I will bear her away on my ship.
"But that these lands of Cornwall and Ireland may know no more hatred, but love only, learn that King Mark, my lord, will marry her. Here stand a hundred knights of high name, who all will swear with an oath upon the relics of the holy saints, that King Mark sends you by their embassy offer of peace and of brotherhood and goodwill; and that he would by your courtesy hold Iseult as his honoured wife, and that he would have all the men of Cornwall serve her as their Queen."
When the lords of Ireland heard this they acclaimed it, and the King also was content.
Then, since that treaty and alliance was to be made, the King her father took Iseult by the hand and asked of Tristan that he should take an oath; to wit that he would lead her loyally to his lord, and Tristan took that oath and swore it before the knights and the Barony of Ireland assembled. Then the King put Iseult's right hand into Tristan's right hand, and Tristan held it for a space in token of seizin for the King of Cornwall.
