Translation:
“Eastman says in several places that the Central Committee” hid “the party a large number of documents of extraordinary importance, written by Lenin during the last period of his life. (These documents are letters on the national question, the famous “Testament,” etc.). This is pure slander against the Central Committee of our party. Eastman’s words express the impression that Lenin wrote these letters, which are advisory in nature and engages with the internal organization of the party, with the intention of having them [the letters] published. This does not accord with the facts. ”
“Eastman’s claims that the Central Committee confiscated my pamphlets and articles in 1923 or 1924, or at any other time or by any means prevented its publications, are false, and are based on rumor fantastic.
Eastman is again mistaken in saying that Comrade Lenin offered me a post of chairman of the Council of People’s Commissars, Council of Labor and Defense and for the first time I heard this book Eastman. ”
“There is sincere worker who believe the picture painted by Eastman. It contains within itself its own refutation. Whatever the intentions of Eastman, this work is spoiled objectively nothing less than a tool of the counterrevolution, and can only serve the enemies of reason incarnate of communism and revolution. “
