On the third day, at the hour of noon, Tristan and Gorvenal came near a hill where an old chantry stood and close by a hermitage also; and Tristan asked what wasted land that was, and the hermit answered: "Lord, it is Breton land which Duke Hod holds, and once it was rich in pasture and ploughland, but Count Riol of Nantes has wasted it. For you must know that this Count Riol was the Duke's vassal. And the Duke has a daughter, fair among all King's daughters, and Count Riol would have taken her to wife; but her father refused her to a vassal, and Count Riol would have carried her away by force. Many men have died in that quarrel."
And Tristan asked: "Can the Duke wage his war?"
And the hermit answered: "Hardly, my lord; yet his last keep of Carhaix holds out still, for the walls are strong, and strong is the heart of the Duke's son Kaherdin, a very good knight and bold; but the enemy surrounds them on every side and starves them. Very hardly do they hold their castle."
Then Tristan asked: "How far is this keep of Carhaix?"
"Sir," said the hermit, "it is but two miles further on this way."
Then Tristan and Gorvenal lay down, for it was evening.
In the morning, when they had slept, and when the hermit had chanted, and had shared his black bread with them, Tristan thanked him and rode hard to Carhaix. And as he halted beneath the fast high walls, he saw a little company of men behind the battlements, and he asked if the Duke were there with his son Kaherdin. Now Hod was among them; and when he cried "yes," Tristan called up to him and said: "I am that Tristan, King of Lyonesse, and Mark of Cornwall is my uncle. I have heard that your vassals do you a wrong, and I have come to offer you my arms.
