1943: Battle of Stalingrad ends

On this day, the last German troops in the Soviet city of Stalingrad surrender to the Red Army, ending one of the pivotal battles of World War II. On June 22, 1941, despite the terms of the Nazi-Soviet Pact of 1939, Nazi Germany launched a massive invasion against the USSR. Aided by its greatly superior air force, the German army raced across the Russian plains, inflicting terrible casualties on the Red Army and the Soviet population. With the assistance of troops from their Axis allies, the Germans conquered vast territory, and by mid-October the great Russian cities of Leningrad and Moscow were under siege. However, the Soviets held on, and the coming of winter forced a pause to the German offensive. For the 1942 summer offensive, Adolf Hitler ordered the Sixth Army, under General Friedrich von Paulus, to take Stalingrad in the south, an industrial center and obstacle to Nazi control of the precious Caucasian oil wells. In August, the German Sixth Army made advances across the Volga River while the German Fourth Air Fleet reduced Stalingrad to a burning rubble, killing over 40,000 civilians. In early September, General Paulus ordered the first offensives into Stalingrad, estimating that it would take his army about 10 days to capture the city. Thus began one of the most horrific battles of World War II and arguably the most important because it was the turning point in the war between Germany and the USSR. In their attempt to take Stalingrad, the German Sixth Army faced a bitter Red Army under General Vasily Zhukov employing the ruined city to their advantage, transforming destroyed buildings and rubble into natural defensive fortifications. In a method of fighting the Germans began to call the Rattenkrieg, or \"Rat\'s War,\" the opposing forces broke into squads eight or 10 strong and fought each other for every house and yard of territory. The battle saw rapid advances in street-fighting technology, such as a German machine gun that shot around corners and a light Russian plane that glided silently over German positions at night, dropping lethal bombs without warning. However, both sides lacked necessary food, water, or medical supplies, and tens of thousands perished every week. Soviet leader Joseph Stalin was determined to liberate the city named after him, and in November he ordered massive reinforcements to the area. On November 19, General Zhukov launched a great Soviet counteroffensive out of the rubble of Stalingrad. German command underestimated the scale of the counterattack, and the Sixth Army was quickly overwhelmed by the offensive, which involved 500,000 Soviet troops, 900 tanks, and 1,400 aircraft. Within three days, the entire German force of more than 200,000 men was encircled. Italian and Romanian troops at Stalingrad surrendered, but the Germans hung on, receiving limited supplies by air and waiting for reinforcements. Hitler ordered Von Paulus to remain in place and promoted him to field marshal, as no Nazi field marshal had ever surrendered. Starvation and the bitter Russian winter took as many lives as the merciless Soviet troops, and on January 21, 1943, the last of the airports held by the Germans fell to the Soviets, completely cutting the Germans off from supplies. On January 31, Von Paulus surrendered German forces in the southern sector, and on February 2 the remaining German troops surrendered. Only 90,000 German soldiers were still alive, and of these only 5,000 troops would survive the Soviet prisoner-of-war camps and make it back to Germany. The Battle of Stalingrad turned the tide in the war between Germany and the Soviet Union. General Zhukov, who had played such an important role in the victory, later led the Soviet drive on Berlin. On May 1, 1945, he personally accepted the German surrender of Berlin. Von Paulus, meanwhile, agitated against Adolf Hitler among the German prisoners of war in the Soviet Union and in 1946 provided testimony at the International Military Tribunal at Nuremberg. After his release by the Soviets in 1953, he settled in East Germany.
