One day, the boys are taken to the trenches on school grounds, where the sports instructor demonstrates use of live stick grenades. Each boy in Friedrich's year makes the throw successfully until one boy, Martin, panics and drops it. The sports instructor screams at him, flees the trench and leaves his students to their fate. Siggi then dives onto the grenade before it explodes, sacrificing himself to save his classmates. Siggi is given a grand funeral at the school and is hailed as a martyr of the Fatherland.

In class the next day, Albrecht reads aloud an essay in which he condemns the execution of the prisoners-of-war; he describes it as a criminal act and that his own participation in it is "evil". Outraged, the school authorities summon his father, who tries to force Albrecht to apologize and retract his previous statements. The boy instead condemns his father for ordering the executions. As a result of this, Albrecht is expelled and Gauleiter Stein drafts him to fight on the Eastern Front. Friedrich hears the news and rushes to meet Albrecht. Devastated at the prospect of them being separated and Albrecht being sent to his death, the two friends begin to fight before holding each other in an emotional embrace.
