Then Bran rose up, and as he did, behold! messengers from Matholluch came before him. They saluted him, and gave him greeting, and said to him: “Matholluch has given the Kingdom of Ireland to Guern, thy nephew, the son of Matholluch and Branwen, and he has done this as an atonement for the wrong that he did to Branwen, thy sister.” To this message Bran would return no answer. The messengers he had sent came back to Matholluch and said: “Lord, prepare a better message for great Bran. He would not listen at all to the message we bore him.”

Matholluch asked his councilors what he might do to win the favor of great Bran. “Lord,” they said to him, “there is no other counsel to be given you except this: it has never been known for Bran to be within a house. Make a house that will hold him—hold him and the men of the Island of the Mighty on one side, and the men of Ireland on the other side, and give over thy kingdom to his will. And by reason of the honor thou dost him in making a house to hold him, he will make peace with thee.” Matholluch agreed to this, and messengers went again from him to great Bran. And when the offer was brought to Bran he accepted it, and peace was made between him and Matholluch.

On the second day Arthur sat on the deck of his ship, and the saints of Ireland were in their coracles around the ship, and Arthur told them of the destruction that was wrought in those days in Ireland, and he told of the return of Branwen to the Island of Britain.
