In late May 1920, after Polish forces had entered Kiev (see Kiev Offensive (1920)), the Red Army began its offensive, which resulted in fast advancing of the Soviets and retreat of Polish forces. In June 1920 in Warsaw, the government of Leopold Skulski was dismissed, and the new cabinet of Wladyslaw Grabski was not created until June 23. The new Prime Minister, well aware of the disastrous situation, created Council of National Defense (July 1, 1920), which was authorized to take decisions regarding the war.
