The Warsaw Uprising (Powstanie Warszawskie) was a World War II struggle by the Polish Home Army (Armia Krajowa) to liberate Warsaw from German occupation. The Uprising began on August 1, 1944, as part of a nationwide rebellion, Operation Tempest. It was intended to last for only a few days until the Soviet Army would reach the city. The Soviet advance stopped short, however, while Polish resistance against the German forces continued for 63 days (until October 2).

The Uprising began at a crucial juncture as the Soviet Army was approaching Warsaw. The Uprising's chief objective was to drive the German occupiers from the city, helping with the larger fight against the Axis. Secondary political objectives were to liberate Warsaw before the Red Army arrived, so as to underscore Polish sovereignty, and to undo the Allied division of Central Europe into spheres of influence. Polish authorities were to reappear in liberated Warsaw and challenge the Soviet puppet government that was to rule Poland.

By September 16, 1944, Soviet forces had reached a point a few hundred metres from the city, across the Vistula River, but they made no further headway during the Uprising leading to allegations that Stalin had wanted the insurrection to fail.

Polish losses amounted to 18,000 soldiers killed and 25,000 wounded, in addition to between 120,000 and 200,000 civilian deaths, mostly from mass murders conducted by retreating German troops. German casualties totalled over 17,000 soldiers killed and over 9,000 wounded. During the urban combat approximately 25% of Warsaw's buildings were destroyed. Following the surrender of Polish forces on October 2, German troops systematically burned the city block by block. Together with earlier damage suffered in 1939 and during the Warsaw Ghetto Uprising (1943), over 85% of the city had been destroyed. By January 1945, when the Soviets finally entered the city, Warsaw had practically ceased to exist.

On September 1st., 1939, 1.8 million German troops invaded Poland on three fronts; East Prussia in the north, Germany in the west and Slovakia in the south. They had 2600 tanks against the Polish 180, and over 2000 aircraft against the Polish 420. Their "Blitzkrieg" tactics, coupled with their bombing of defenceless towns and refugees, had never been seen before and, at first, caught the Poles off-guard. By September 14th. Warsaw was surrounded. At this stage the Poles reacted, holding off the Germans at Kutno and regrouping behind the Wisla (Vistula) and Bzura rivers. Although Britain and France declared war on September 3rd. the Poles received no help - yet it had been agreed that the Poles should fight a defensive campaign for only 2 weeks during which time the Allies could get their forces together and attack from the west.

There are many "myths" that surround the September Campaign; the fictional Polish cavalry charges against German tanks (actually reported by the Italian press and used as propaganda by the Germans), the alleged destruction of the Polish Air Force on the ground, or claims that Polish armour failed to achieve any success against the invaders. In reality, and despite the fact that Poland was only just beginning to modernise her armed forces and had been forced (by Britain and France) to delay mobilisation (which they claimed might be interpreted as aggressive behaviour) so that, at the time of invasion, only about one-third of her total potential manpower was mobilised, Polish forces ensured that the September campaign was no "walk-over". The Wehrmacht had so under-rated Polish anti-tank capabilities (the Polish-designed anti-tank gun was one of the best in the world at that time) that they had gone into action with white "balkankreuz", or crosses, prominently displayed in eight locations; these crosses made excellent aiming points for Polish gun-sights and forced the Germans to radically rethink their national insignia, initially overpainting them in yellow and then, for their later campaigns, adopting the modified "balkankreuz" similar to that used by the Luftwaffe. The recently-designed 7TP "czolg lekki", or light tank, the first in the world to be designed with a diesel engine, proved to be superior to German tanks of the same class (the PzKpfw I and II) inflicting serious damage to the German forces, limited only by the fact that they were not used in concentrated groups. They were absorbed by the Germans into their own Panzer divisions at the end of the campaign.

On September 17th. Soviet forces invaded from the east. Warsaw surrendered 2 weeks later, the garrison on the Hel peninsula surrendered on October 2nd., and the Polesie Defence group, after fighting on two fronts against both German and Soviet forces, surrendered on October 5th. The Poles had held on for twice as long as had been expected and had done more damage to the Germans than the combined British and French forces were to do in 1940. The Germans lost 50,000 men, 697 planes and 993 tanks and armoured cars.

Thousands of soldiers and civilians managed to escape to France and Britain whilst many more went "underground" . A government-in-exile was formed with Wladyslaw Raczkiewicz as President and General Wladyslaw Sikorski as Prime Minister.
The Fourth Partition:

Under the German-Soviet pact Poland was divided; the Soviets took, and absorbed into the Soviet Union, the eastern half (Byelorussia and the West Ukraine), the Germans incorporated Pomerania, Posnania and Silesia into the Reich whilst the rest was designated as the General-Gouvernement (a colony ruled from Krakow by Hitler's friend, Hans Frank).

In the Soviet zone 1.5 million Poles (including women and children) were transported to labour camps in Siberia and other areas. Many thousands of captured Polish officers were shot at several secret forest sites; the first to be discovered being Katyn near Smolensk and elsewhere.

The Germans declared their intention of eliminating the Polish "race" (a task to be completed by 1975) alongside with the Jews. This process of elimination, the "Holocaust", was carried out systematically. All members of the "intelligentsia" were hunted down in order to destroy Polish culture,heritage and leadership (many were originally exterminated at Oswiecim - better known by its German name, Auschwitz and many other concentration camps). Secret universities and schools, a "Cultural Underground", were formed (the penalty for belonging to one was death). In the General-Gouvernement there were about 100,000 secondary school pupils and over 10,000 university students involved in secret education
