The Russian Imperial Navy did not die in 1917. Its best representatives, officers and admirals, came to the defense of the empire. Squadrons and flotillas were created on the Baltic, Black, Caspian and Barents Seas, on the Onega and Ladoga Lakes, on the Volga, Kama, Shilka and Angara, on the ships of which, as before, the St. Andrew's flag was hoisted. A new book by military historian O.G. Goncharenko tells about the life of Russian sailors, their participation in the Civil War and their fate after its end.
