The Germans called it Rattenkrieg. The war of rats. By September 1942, the German 6th Army had pushed into Stalingrad and was fighting through a city reduced to rubble — rubble that made the defenders' task easier. Every collapsed building became a fortress. Every cellar an ambush point. Every metre of ground cost lives.

The Advance

Operation Case Blue launched in June 1942 with spectacular initial advances. By August, the 6th Army under General Friedrich Paulus had reached Stalingrad's outskirts. The Luftwaffe conducted a massive bombing campaign that reduced much of the city to ruins. The Soviets continued to fight from the ruins, supplied by night in small boats under constant artillery fire.

The German strategy — clear the city floor by floor — worked slowly and at terrible cost. Soviet defenders held on to the Barrikady factory complex, the grain elevator, Mamayev Kurgan, and the bank of the Volga itself, fighting with minimal room — at the height of the battle, Soviet defenders held a strip less than 500 metres wide in some places.

Operation Uranus

While brutal attritional fighting consumed German attention in the city, Soviet planners developed Operation Uranus: a double envelopment striking not at Stalingrad itself but at the German flanks, held by underequipped Romanian, Hungarian, and Italian allied forces.

On November 19, 1942, Soviet forces north of Stalingrad attacked. On November 20, Soviet forces south attacked. Within four days, both arms had closed at Kalach, on the Don River. The German 6th Army — approximately 290,000 men — was encircled.

The Kessel

The encirclement trapped approximately 300,000 men. The Luftwaffe promised 500 tons of supply per day. Actual delivery averaged approximately 100 tons. Field Marshal von Manstein's relief operation came within approximately 35 miles of the pocket before being halted. Paulus declined to break out without Hitler's permission. Hitler refused.

Through January 1943, the pocket contracted. Men were starving. Frostbite claimed as many casualties as Soviet fire.

The Surrender

On January 30, 1943, Hitler promoted Paulus to Field Marshal. No German Field Marshal had ever surrendered. The promotion was understood as an instruction. Paulus surrendered his command on February 2, 1943.

Approximately 91,000 German and Axis soldiers went into Soviet captivity, including 24 generals and Paulus himself. Estimates of survivors who eventually returned to Germany range from approximately 5,000 to 6,000 men.

What Stalingrad Changed

Before Stalingrad, the Wehrmacht had never suffered a defeat of this magnitude. The loss of an entire army group, the surrender of a Field Marshal — these were devastating events that could not be concealed from the German public. The Propaganda Ministry declared three days of national mourning.

Strategically, Stalingrad marked the definitive turning of the Eastern Front. Germany never again launched a major strategic offensive in the East. From February 1943, the question was not whether Germany would lose the war in the East, but when and at what cost.
