Attacks on this day
U-196. U-196 attempted to fire two torpedoes at a target in a convoy off South Africa, but only one launched, leaving the other lodged in its tube armed and ready to detonate. The potentially catastrophic hazard was removed by diving the boat at a steep angle until it slid out of the tube. During all this, convoy escorts dropped four depth charges on the boat, but without causing any damage. Date is approximate. (Blair, vol 2, page 298)
U-853. Rockets were fired by two Swordfish torpedo bombers from the British MAC ships HMS Ancylus and HMS Empire MacKendrick escorting convoy ON 237. The boat fought off the attack with AA fire and escaped undamaged. All three aircraft were hit by flak, M3 from HMS Empire MacKendrick so badly that it was jettisoned on its return.
U-276. 01.50 hrs, Norwegian Sea: surprise attack by a British B-24 Liberator (59 Sqdn RAF/C) in bad weather. The aircraft strafed the U-boat heavily and carried out two bombing runs, dropping six and then two depth charges. However, the bomb aimer had accidentally turned off the fusing switches while adjusting his intercom plug during the approach, which meant the depth charges didn't detonate. U-276 could only put up light and inaccurate flak at first because the 37mm gun malfunctioned after the first round, three of the 20mm twin gun crew were wounded, and two more men were injured when hit by waves. The U-boat escaped by crash diving after the second attack and made for Trondheim to land the wounded. [Maschinenmaat Hans Liedtke died from his wounds on 26 May] (Ritschel, ADM 199/1786)
1943: U-414 +, U-467 +
