The memoirs of Georgy Mikhailovich Semenov tell the reader about the difficult fate of a Russian officer during the First World War. The Civil War brought the young Cossack officer to the forefront. A separate Manchurian detachment of Ataman Semenov caused concern not only among the Bolsheviks, but also among the Supreme Ruler of Russia, Admiral Kolchak. In his memoirs, the author talks about difficult relationships with the Japanese, the leaders of the White movement and with his comrades. While in exile, G. M. Semenov made an attempt to comprehend the defeat of the White Army and project the further course of history. These thoughts organically complement the memoirs of G. M. Semenov and show his varied interests.
