Prince Caspian was on the run from his uncle Miraz, who wanted his crown, so he sided with the Old Narnians, to fight back and reclaim his throne, and return to the Narnians their land. He used Queen Susan's Horn to summon the Pevensies back to Narnia. To avoid as much bloodshed as possible, a challenge was delivered through King Edmund to the newly crowned King Miraz, who accepted, though it was done so by appealing to his arrogance and pride. Peter and Miraz then started fighting again, this time each giving their full strength, but then Miraz slipped on a tussock and fell.
