The escort carrier USS Shamrock Bay, 1944 (CC0 1.0 Universal)
The Battle of the Atlantic was the longest and most technologically dynamic campaign of the Second World War, a vast contest in which engineering ingenuity, intelligence breakthroughs, and industrial capacity proved as decisive as bravery at sea. In a richly illustrated lecture, U.S. Naval Academy historian Marcus Jones offers a sweeping yet accessible narrative of the struggle from 1939 to 1945, tracing the evolution of German U-boat design and doctrine and the early successes that placed Britain’s maritime lifeline in peril.
He explains how the Allies—drawing on convoys, radar, high-frequency direction finding, long-range aircraft, and the revolutionary development of escort carriers—slowly assembled a counter-system capable of meeting the submarine threat head-on. The story of Bletchley Park and its American partners forms a central thread: the breaking of the German navy’s Enigma cipher machine turned intelligence into a weapon and helped to reshape the campaign’s technological and operational trajectory.
At its heart, however, the Atlantic Campaign was a profoundly human ordeal, says Jones. Drawing on the latest scholarship and vivid historical accounts, he presents the Atlantic war as a complex, interlocking system, one in which science, strategy, and endurance combined to determine the fate of nations: a story of innovation under pressure and survival against the odds.
