There has never been such a book! In the quarter of a century that has passed since the collapse of the USSR, not a single full-fledged analytical work has been created on the actions of the Soviet fleet in the Great Patriotic War. Either revisionist “revelations” or analyzes of individual battles have been published - but generalizing works that comprehend the situation as a whole have not yet been published. This book is the first. In a new study by leading Navy historians, based on materials from both domestic and Western archives, you will find not only comprehensive information about the combat use of the Black Sea Fleet in the Great Patriotic War, but also a professional assessment of the plans of the parties and their implementation, as well as unique statistical data published for the first time.
