After the duel, Don Sanche (Chimène's champion), carrying a bloody sword, comes to where she is waiting. Chimène assumes the worst without giving him the chance to speak. Going before the king, she finally feels free to confess her love for Rodrigue because she believes him to be dead. Don Sanche then explains that Rodrigue disarmed him and granted him mercy. After the duel, Rodrigue returns straight to the king, leaving Don Sanche to bring his sword to Chimène.
Although they love each other, Chimène and Rodrigue are reluctant to marry because of their history, but the king says that although it seemed impossible at first, circumstances have proven that they were meant to be together. Still, he realizes they need time to adapt. Chimène will set the date for the wedding, up to a year in advance. Meanwhile, Rodrigue, known as the Cid, will conduct a war against the Moors in their own territory.
