A secret part established spheres of interest in Eastern Europe, and a border between both countries existed after they had invaded and divided Poland.[1]
Only nine days later, on 1 September 1939, the German invasion of Poland began. On 17 September, the Soviet invasion of Poland began.
About 250,000 to 454,700 Polish soldiers and policemen were captured and interned by the Soviet authorities. About 125,000 were imprisoned in camps run by the NKVD, and 43,000 soldiers born in western Poland, which was under German control, were transferred to the Germans. In turn, the Soviets received 13,575 Polish prisoners from the Germans, which showed how close the co-operation was between the Germans and the Soviets.[2]
On 3 September, France and the United Kingdom declared war soon because both had promised to defend Poland if it was attacked. Since neither of them was ready for war, they did nothing to help Poland for some time, but the Second World War clearly had started on that day.[3]
Hitler later broke the pact in June 1941 by invading the Soviet Union in Operation Barbarossa. The war would end by the Soviet victory in 1945.
