The Warsaw Uprising is a revolution that takes place in Poland against the Nazi thoughts of Germany that predominated in the Second World War.
When the Uprising began, the Red Army was tens of kilometers from the capital, and when they arrived on September 16, they only had to cross the Vistula River to liberate Warsaw. However, the Soviets stopped, leading most historians to conclude that Stalin preferred the uprising to fail, in order to more easily rule Poland during the Cold War years. The Soviets, for their part, assured that they stopped their advance due to supply problems, since their supply lines had been overextended since Operation Bagration.
Explanation:
Following Soviet orders, some suspected that Stalin planned to keep the country; Poland had already been invaded by the Soviet Union on September 17, 1939. After the Yalta Conference (1945) it was annexed, Sovietized, and the Poles of the Warsaw Uprising imprisoned, executed, or exiled.
The Poles understood that they could not expect outside support, although they continued the fight in the hope that the resistance would force the Germans to lessen the harshness of the conditions of surrender.
