Left-wing uprisings against the Bolsheviks
The main rebel force was a detachment commanded by Dmitry Ivanovich Popov, a Left S.R. and member of the Cheka. About 1,800 revolutionaries took part in the insurrection, bombarding the Moscow Kremlin with artillery and seizing the telephone exchange and telegraph office. During the two days that they remained in control there, they sent out several manifestos, bulletins and telegrams in the name of the Left S.R. Central Committee declaring that the Left S.R.s had taken over power and that their action had been welcomed by the whole people. The Fifth Congress of Soviets instructed the government to suppress the insurrection at once, and the group of Left S.R.s at the Congress was arrested.
