In the summer of 1943, Hitler gambled his last reserves of armor on a salient around Kursk, hoping to seize the initiative on the Eastern Front after the catastrophe at Stalingrad. This film lays out how Germany massed thousands of tanks, including new Panther and Tiger models, against a Red Army that had spent months turning the salient into a defensive fortress of minefields, anti-tank guns, and layered trenches. Archival footage and maps trace the fighting at Prokhorovka and along the northern and southern shoulders of the salient, showing how Soviet commanders absorbed the German assault before grinding it down. The film covers the scale of resources both sides committed, the intelligence advantages that let Stalin's generals prepare for the exact German plan, and the way the battle drained Germany's offensive capacity on the Eastern Front for good. It treats Kursk as the moment initiative passed permanently to the Soviets, setting up the long retreat that ended in Berlin.
