Greatly was the King of Aragon displeased at this which King Don Sancho had done. He required he should yield unto him all the spoil which the King of Zaragoza had given him, else should he not pass without battle. King Don Sancho, being a man of great heart, made answer that he was the head of the kingdoms of Castille and Leon, and all the conquests in Spain were his. Wherefore he counselled him to waive his demand, and let him pass in peace. But the King of Aragon drew up his host for battle, and the onset was made, and heavy blows were dealt on both sides, and many horses were left without a master. And while the battle was yet undecided, King Don Sancho riding right bravely through the battle, began to call out Castille! Castille! and charged the main body so fiercely that by fine force he broke them; and when they were thus broken, the Castillians began cruelly to slay them, so that King Don Sancho had pity, and called to his people not to kill them, for they were Christians. Then King Don Ramiro being discomfited, retired to a mountain, and King Don Sancho beset the mountain round about, and made a covenant with him that he should depart, and that the King of Zaragoza should remain tributary to Castille; and but for this covenant the King of Aragon would then have been slain, or made prisoner. In all these wars did my Cid demean himself after his wonted manner; and because of the great feats which he performed the king loved him well, and made him his Alfarez, [Footnote: A standard bearer] so that in the whole army he was second only to the king. And because when the host was in the field it was his office to choose the place for encampment, therefore was my Cid called the Campeador.
