After a while, the king sends his nephew Arthofilaus to demand that Galiene surrender the castle. She refuses, but they agree that if she can find a suitable knight, they will settle the dispute by single combat. Galiene soon regrets the deal, as she is unable to find a willing candidate among her men. She therefore sends her attendant, Arondele, to request a knight from Arthur at Carlisle. However, Arthur is unable to provide one because all of his knights are out searching for Fergus. Dejected, Arondele heads back to her mistress. On the way, she passes Melrose and relates the story to Fergus, before returning to Roxburgh. News of the attendant's failure brings Galiene to grief, because the combat must take place the following day. When the time arrives, Galiene prepares to throw herself from the castle tower. However, she catches sight of a shining shield in the distance. The mysterious knight slays Arthofilaus, and the king gives up his claim to Lothian. It is then that Galiene learns the identity of the knight, her lost love Fergus. By then, however, he had already departed.
