The book is devoted to the history of the creation and participation in the Great Patriotic War of one of the ships of the Black Sea Fleet - the leader of the destroyers "Moscow." For many years, the authors independently investigated this topic and only at the final stage decided to unite their efforts. The emphasis in the book is on the pre-war campaigns of the ship and the only military operation on June 26, 1941, in which the leader "Moscow" took part. As you know, during the shelling of Constanta, the leader died.
