When the King of Aragon demands the city of Calahorra from Castile, Rodrigo becomes Ferdinand's champion, winning the city in single combat. In his new capacity he is sent on a mission to collect tribute from Moorish vassals to the Castilian crown. He asks that Chimene be given to him as his wife upon his return, so that he can provide for her. Chimene promises Count Ordóñez she will marry him instead if he kills Rodrigo.
