Attacks on this day


U-53. Swordfish torpedo bombers from the British aircraft carrier HMS Courageous fired on the boat and forced her to dive. Some gunners who were left topside perished. Later that day HMS Courageous was sunk by U-29. (Blair, vol 1, page 90)

U-29. Following her sinking the British aircraft carrier HMS Courageous, British destroyers pursued U-29 for four hours, until they ran out of depth charges. The boat escaped with minor damage. (Blair, vol 1, page 90)

U-36. British submarine HMS Seahorse (96 S) fired a spread of three torpedoes at U-36, which had just stopped to question a neutral Danish steamer. The U-boat was lucky to escape harm, as one of the torpedoes passed directly underneath her. (Dr. Jürgen Rohwer, Herbert Ritschel)


U-506. An American B-24 Liberator bomber piloted by James D. Harden attacked the boat - carrying 151 survivors from the Laconia, 142 of whom were on deck - but the boat dived and escaped unharmed. Harden had attacked U-156 the day before. These attacks resulted in Dönitz's Laconia Order. (Blair, vol 2, page 64.)
