September Campaign

The September Campaign began on September 1, 1939, with Germany's attack on Poland, and on September 17, the Soviet Union joined the invasion. Despite heroic defense, including the symbolic defense of Westerplatte, the military superiority of the aggressors led to Poland's defeat. The campaign ended on October 6, 1939, with the capitulation of the last regular units at Kock.

September 17, 1939

Soviet Invasion of Poland

On September 17, 1939, the Soviet Union, breaking existing international treaties, launched a military invasion of Poland. The attack was the implementation of the secret protocol of the Ribbentrop-Molotov Pact and occurred when Poland was fighting a desperate battle against Nazi Germany. About 600,000 Red Army soldiers, supported by 4,700 tanks and 3,300 aircraft, crossed Poland's eastern border, beginning a period of Soviet occupation and mass repression against civilians.
