Attacks on this day

1942

U-123. After sinking Gulfamerica the boat was located in shallow water by an aircraft which directed a destroyer to the position. At 09.17 hrs, six depth charges were dropped as U-123 was moving over the bottom at a depth of 20m (66 ft), badly damaging her. The boat "played dead", and despite air bubbles escaping from damaged valves, no more depth charges were dropped by the destroyer, which left after an hour. Most of the damage could be repaired, and the boat continued the patrol. (KTB U-123)

1944

U-803. Five men from the boat died during an air raid on Stettin (Szczecin, Poland).

U-621. Returning from patrol in the Atlantic U-621 ran into an Allied hunter-killer group 900 miles (1,448 km) from her base and fired a torpedo at a "destroyer", but missed. The boat then evaded the hunters and docked at Brest. (Blair, vol 2, page 496)

U-255. After being attacked by aircraft off Gibraltar on 27 March the inbound U-255 was caught on the surface with her escort by 15 British Mosquito aircraft. These were in turn attacked by German Ju-88 aircraft. The boat reached St. Nazaire with minor damage. (Blair, vol 2, page 508)

U-362. The boat was attacked by a Martlet aircraft in the Norwegian Sea and damaged so severely that she had to return to base.

General Events on 11 April

1940

U-5 encountered a British submarine and fired one torpedo, but without success.

U-7 put ashore a landing party to occupy the Marstein lighthouse in Norway.

1941

The US destroyer USS Niblack (DD 424) dropped three depth charges on a "U-boat" sonar contact after picking up survivors from the Dutch merchant Saleier, sunk by U-52 the day before. This event is known as the first military action between the USA and Germany in the Second World War, but it seems the destroyer identified a spurious contact, because there was no U-boat in the vicinity at the time.

1943

U-615 was slightly damaged by debris when the Liberty ship Edward B. Dudley exploded after being hit by a coup de grâce from a distance of 800m. The commander was wounded and the U-boat was forced to return to base.

1945

U-486 had to return from patrol when the Schnorchel failed.
