Dmitry Vsevolodovich Nenyukov (1869-1929) - 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 World War I, then commander of the Danube Flotilla and already during the Civil War the commander of the Black Sea Fleet. Memories begin with a description of the first days of the war and the author's arrival at the Headquarters of the Supreme Commander and end with his resignation from the Volunteer Army and emigration in 1920. The testimony of a person who was in the thick of things during a dramatic historical period is an invaluable historical source of the period of the First World War and revolution.
