The final part of S. P. Melgunov’s book “The Tragedy of Admiral Kolchak” is devoted to an analysis of the reasons that led Kolchak’s army to defeat in the confrontation with anti-state forces. The direct and impeccably honest Admiral, who took on the burden of the Supreme Ruler and dreamed of restoring Great Russia, faced not only an obvious enemy in the face of the Bolsheviks, but also the double-dealing policy of the Allied command, the personal ambitions of the Siberian atamans who did not want to recognize the constitutional dictator, the actions of international adventurers who lived fat in the conditions of Russian misfortune, and the direct betrayal of party functionaries who conspired with the Bolsheviks. The history of the last days of Admiral Kolchak is a story of meanness and betrayal of the national interests of Russia, which our contemporaries should know about.
