Nikolai Zenkovich, the author of more than 20 books of exciting historical investigations published in the “Dossier” series, created a unique work - the dramatic chronicle “The 20th Century. The highest generals in the years of upheaval." Having split the Russian army into two at the beginning of the century - White and Red, the generals ultimately destroyed Russian statehood and themselves. At the end of the century, the army, this time the Soviet one, split again, and again the sad result was the loss of the state. In both cases, the favorite weapons of the generals were denunciations and betrayal, perjury and slander.
