Under these conditions, according to Boris Savinkov's plan, the "Union for the Defense of the Motherland and Freedom" was supposed to raise an uprising in the central regions and then defeat the Bolsheviks with the help of the Entente's intervention.

The main force of the rebels was to be regular officers of the tsarist army, as well as local residents, workers, peasants, members of the banned Menshevik, constitutional democrats parties, and so on, dissatisfied with the actions of the Bolsheviks.

The gathering places of five detachments of the "Union" were blocked by the Workers' and Peasants' Red Army, employees of the All–Russian Extraordinary Commission and the militia.

At about 3:00, he was able to occupy the Myrka Military Barracks in the west of the city (now at the intersection of Svoboda and Herzen Streets) without resistance and seize the machine guns and rifles stored in them.

For some time, Savinkov's detachment was engaged in sabotage on the railway in order to interfere with the supply of the troops besieging Yaroslavl, but then disintegrated.
