This is the account of machines of war pitted against each other and the combatants who operated them. Step onto the battlefield and immerse yourself in the experience of real historic combat. Although the Battle of the Atlantic lasted several years, its most critical phase began once the United States entered World War II. By December 1941, the British had mastered the U-boat threat in the eastern Atlantic, only to see the front abruptly expand to regions the US Navy would patrol, chiefly the Atlantic Seaboard. Unless the US Navy overcame the U-boat threat, the Allies would struggle to win. The Battle of the Atlantic was made up of thousands of individual duels, with aircraft facing U-boats, ships, and other aircraft. Most crucially, however, ships battled U-boats. These stories provide the focus of this detailed work. The technical specifications of the U-boats, destroyers, and destroyer escorts involved are explored in stunning illustrations, including ship and submarine profiles and weaponry artworks, while key clashes are brought to life in dramatic battlescenes. Among the clashes covered are USS Kearny vs U-568, USS Roper (DD-147) vs U-85, USS Eugene E. Elmore (DE-686) vs U-549, and USS Atherton (DE-169) vs U-853.
