Attacks on this boat and other events
10 Nov 1942
09.07 hrs, ,Bay of Biscay inbound: boat was surprised by a B-24 Liberator bomber (59 Sqn RAF/C), which dived out of clouds and dropped a stick of six 250lb depth charges in a strafing attack from the port beam. Two fell short, the third bounced off the aft part and the remainder fell over the U-boat which crash dived immediately afterwards. However, the Liberator succeeded in attacking again after a climbing turn, and dropped a second stick of six 250lb depth charges off the starboard beam just ahead of the conning tower, still was visible on the surface. U-436 was badly shaken by the explosions, the rudder and manometer were disabled, the lights went out and many valves sprang open. It seems that the Germans had some difficulty getting the boat under control, as the crew of the aircraft reported that its bow was seen to raise gradually to 60°, until some 15ft were visible. They machine gunned it at close range for six minutes until the U-boat settled down on an even keel and submerged almost stationary, leaving behind a patch of oil and possibly debris. After temporary repairs, the U-boat managed to reach Lorient on 12 November. (Sources: KTB U-436, ADM 199/1783)
