The era of war communism is still far from being studied. For our party, as well as for other sections of the Comintern, which, after gaining power, will have to wage an “economic assault” in conditions of war and blockade, this era is of invaluable interest. That under certain conditions (war, blockade, continuous bourgeois and petty-bourgeois onslaught on the dictatorship of the proletariat) war communism is an inevitable and vital stage in the development of the proletarian dictatorship is hardly in doubt. All the more important is a comprehensive study of this era in the interests of tomorrow's proletarian revolution in other countries. We hope that the publication of this volume, despite the extreme insufficiency of the materials collected in it, will serve its purpose in this regard.
