Kolp's scouts find Ape City. Believing Caesar is planning to finish off all mutant humans, Kolp declares war on Ape City despite his assistant Méndez's attempt to get him to see reason. Aldo plots a coup d'état in order for the gorillas to take control. Cornelius overhears from a nearby tree, but is critically wounded when Aldo spots him and hacks off the tree branch he is on with his sword. The next day, after a gorilla scouting pair are attacked by Kolp's men, Aldo takes advantage of a grieving Caesar's absence to have all humans corralled while looting the armory. Cornelius eventually dies from his wounds, leaving a devastated Caesar with the revelation that Cornelius was not hurt by humans.
