Waffen, Hände, Herzen 1944

This armaments-related propaganda film documents, among other things, rare contemporary footage of the Third Reich’s top-secret underground construction sites. Specifically, the scenes were filmed in Kahla, Thuringia; there, under extremely inhumane conditions, foreign forced laborers were primarily tasked with driving forward the construction of an underground aircraft factory—codenamed "Lachs" (Salmon)—within the tunnels of the Walpersberg mountain to produce the Messerschmitt Me 262 jet fighter.

The title is derived from the "hold-out" slogan common at the time—"Weapons, Hands, and Hearts for Victory!"—which was intended to symbolize the total mobilization of the arms industry, the workforce, and ideological resolve during the final phase of World War II.
