Once they arrived, Peter killed Maugrim to protect Susan and Lucy. One of the other wolves made it back to the White Witches camp, which got invaded by Aslan's army. The following morning, Peter saw Edmund at the top of hill, apologizing to Aslan for his actions. The White Witch demanded a meeting with Aslan which was revealed by Mr. Beaver. After Aslan was killed, Mr. Beaver prepared Edmund for war. Edmund tried to kill the White Witch, but she managed to stab him in the stomach. During the war, Aslan returned from the dead and killed the White Witch.
