Stories of Charlemagne and the Twelve Peers of France by Alfred John Church

When King John of Gascony heard all the trouble that had befallen the / brethren, on the one side, and the Emperor and his knights, on the / other, he could not rest, so much did his conscience trouble him. So / having bidden farewell to his sister Clare, Reynaud's wife, he sought / a certain Abbey, and there took a monk's habit. But a certain man / that was a spy was aware of the matter, and told it to Roland. Also / he said that the brethren and Mawgis were journeying to Montalban. / Then Roland, having first called Oliver, said, "We will go now and / fight with the sons of Aymon, and we will take four thousand men only / with us, so that we shall have no advantage over them, inasmuch as / they have five thousand well horsed and well armed. " Said Ogier the / Dane, "I will go with you and see how you fare, and I promise that if / you lay hands on them I will lend you a rope."

Roland first came to the Abbey, and said to the Abbot. "You have / here in a monk's habit a certain John, whom men call King of Gascony. / Deliver him to me that I may hang him as a thief. " And when the / Abbot would not consent, Roland entered the cloister, and took King / John by force, the man being known to him, and set him on a horse, / with his face to the tail. The King said to a certain knight whom he / knew, "Go now to Reynaud and say that I am in sore straits. " "Sir," / said the knight, "I doubt whether Reynaud will so much as stir a foot / to help you. " Nevertheless he consented to go.
