🌊 Though May 1943 marked the turning point against U-boats, the Germans had no idea they'd lost the Battle of the Atlantic until two months later, when their intelligence finally recognized the massive losses. ⚔️ Author Michael Gannon served as a U.S. Navy Reserve officer and spent over 30 years as a professor at the University of Florida, bringing both military and academic expertise to his analysis. 🚢 The Allies' success in May 1943 was so complete that U-boats lost 41 of their submarines that month - more than one per day - representing 25% of Germany's operational U-boat fleet. 📡 The book reveals how breaking the German Enigma code was only one factor in victory - equally important were advances in radar, sonar, and aircraft technology. 🎯 Before the events of "Black May," German U-boats were sinking Allied ships faster than they could be built, destroying about 650,000 tons of shipping per month in early 1943.
