Summer 1942: with the Crimea secured, Hitler splits his southern offensive in two, sending Army Group A along the Black Sea coast toward the oil fields of Maikop, Grozny, and Baku while Army Group B pushes alone toward Stalingrad. This film lays out the decision historians point to as one of Hitler's costliest, tracing how dividing an already stretched force left Army Group B without the strength to take and hold the city on the Volga. Archival footage, maps, and battlefield photographs track the German advance across the steppe and the Soviet resistance that hardened around Stalingrad's ruins. Historians walk through the strategic logic Hitler was chasing, oil to fuel his war machine, and the arithmetic of manpower and supply lines that undid it. The narrative builds toward the encirclement that would trap the Sixth Army, showing how a single command decision, made months before the fighting reached the city, set the terms for one of the war's turning points.
