Miraz agrees to duel with Peter to the death. Peter wins and offers to let Caspian finish Miraz off. Caspian lets Miraz live. Lord Sospespian kills Miraz with a Narnian arrow and tells his army the Narnians did it. The army lays siege. Lucy finds Aslan, who awakens the trees and the river god to help defeat the attacking army. Caspian becomes king of Narnia. Aslan offers the Telmarines to go back to their island of origin and reveals that their ancestors were pirates who came to Narnia through a portal in an island cave. General Glozelle, Miraz's wife Prunaprismia and other Telmarines go through a portal Aslan creates. Peter and Susan tell the others they'll never return to Narnia, though Lucy and Edmund probably will. The Pevensies then step through the portal and are back at the train station.
