To the Executive Commission of the Petrograd Committee and to all district committees of the Bolshevik Party, we advise, without losing an hour, to rouse all the workers, so that, in accordance with the decision of the Petrograd Soviet, which is to be adopted this evening, tens of thousands of workers be organized and the entire bourgeoisie be driven out en masse, under the workers' control, to dig trenches near Petrograd. Now, when the revolution is in danger, only this is the salvation of the revolution. The line of the trenches will be provided by the military; prepare weapons, and most importantly – organize and mobilize yourselves en masse.
