Apparently, they managed to pick up some mail at the last outpost. Chef hands it around, and they read their mail. One of them gets a newspaper piece about Charles Manson.
Willard gets a classified message, telling him that the army earlier had sent another man, Colby, to kill Kurtz. But this dude switched sides, it seems, joining up with Kurtz.
Suddenly, from both sides of the river, enemy fire starts blazing.
Mr. Clean gets killed, and Lance can't find the dog. A tape Mr. Clean received from home is still playing—his mother's voice, telling him to come home safe and dodge the bullets.
Further down, journeying through smoke from a smoke grenade thrown by Lance, Chief wants to stop the boat because they can't see anything. They can't figure out why no one's attacked, since there are apparently enemies around.
Just then, a hail of arrows falls on them. But they're just toy arrows, trying to scare them off. They're from Kurtz's people, the tribal warriors who fight for him.
The Americans fire back with machine guns, and then the tribes get serious. A spear goes straight through Chief.
As Chief lies dying, he tries to strangle Willard but gets too weak and collapses, dead.
After getting away from the arrows, Willard finally admits his mission to Chef and Lance. He's journeying all the way to Cambodia to kill Kurtz, who's crazy.
Chef finds that typical—what a psycho mission. But he and Lance agree to go along.
