Attacks on this day


U-755. 06.26 hrs, 13 miles north of Alboran Island in the Mediterranean: the boat was attacked by a British Hudson bomber (500 Sqdn RAF, pilot S/L H.G. Holmes, DFC). Three depth charges were dropped by the aircraft during the first attack run, despite being hit in the port engine by flak, and followed up with two dive-bombing attacks, dropping first two and then one A/S bomb, one of which exploded only five yards (4.6m) off the port beam. The engine damage then forced the aircraft to return to base. One of U-755s crew was killed and two wounded by strafing, and the boat was forced to return to base due to heavy damage. She was sunk in another air attack two days later. (Franks/Zimmerman)


U-958. One man died and two were wounded in an attack by two Mosquito aircraft (RAF Sqdn 333/N/E). [Maschinenobergefreiter Herbert Frank]

U-541 stopped the neutral Portuguese passenger liner Serpa Pinto, en route to Canada south of Bermuda. The Germans found contraband for the USA and Mexico on board, and men of military age from enemy countries and Jewish refugees among the 200 passengers. All hands were ordered to abandon ship, but the BdU instructed the commander not to sink her. The crew and passengers were allowed to reboard the ship after nine hours, but three had died during the vessels evacuation. Two American passengers were taken prisoner and landed at Lorient on 22 June.
