Petrograd, Jan 24. The third All-Russian Congress of Workmen’s and Peasants’ delegates opened here yesterday. Addressing the foreign delegates, M Trotsky said: “Many efforts and much energy are needed to conquer the capitalist hegemony of Europe, where capital has dominated for generations not only the bourgeois class but that of the workmen also. As regards the struggle against the ancient systems of Europe and America, we have no need to be pessimistic. Our foreign comrades are the precursors of a general and invincible revolt. The movement is slow but sure.
