The Battle of the Atlantic is a significant episode in maritime history. Taking place during the Second World War, it became a grandiose battle for dominance of the Atlantic communications between the naval forces of the Axis countries and the allies of the anti-Hitler coalition. Germany relied on submarine warfare, trying to strangle Great Britain with a naval blockade, destroying its merchant ships. German submarines were active in the Atlantic, posing a serious threat to Allied shipping. Over time, the heat of underwater warfare spread to other areas of the world's oceans. The commander of the German submarine forces, Karl Doenitz, skillfully used “wolf pack” tactics against allied convoys, while simultaneously striking at the enemy’s weak points in distant communications. Vladimir Nagirnyak’s new book is a detailed account of the people and operations of the Battle of the Atlantic. Its heroes and victims.
