'Duzy Projekt' was a Polish resistance movement plan for a national rising against the Germans to coincide with the arrival of Soviet forces from the east (summer 1944).

The result of the plan’s completion and implementation was the 'Burza' national rising in Warsaw, which was started in the expectation of Soviet help from the eastern bank of the Vistula river at the end of 'Bagration'. For political and logistical reasons the Soviets were unwilling and/or unable to furnish useful material support to the pro-Western Allied forces in the city, and in a campaign of ruthless devastation the Germans were able to use SS forces to put down the rising without Soviet hindrance.
