Dmitry Vsevolodovich Nenyukov (1869–1929) is one of the prominent representatives of the Russian military elite, a participant in the Russo-Japanese War, a representative of the navy at Headquarters at the beginning of the First World War, then the commander of the Danube Flotilla and already during the Civil War the commander The Black Sea Fleet. The memoirs begin with a description of the first days of the war and the author’s arrival at the Headquarters of the Supreme Commander-in-Chief and end with his resignation from the Volunteer Army and emigration in 1920. The testimony of a man who was in the thick of things during a dramatic historical period is an invaluable historical source of the First World War and the Revolution.
