Attacks on this boat and other events

17 Oct 1941
At 05.30 hrs the boat was sighted by HMS Broadwater off the port beam of convoy SC 48. The destroyers forward gun was inoperable due to weather damage and the starboard 4in gun jammed when firing a star shell, so she tried to ram U-432, which turned inside the destroyers radius, and then quickly dived after attempting to escape at full speed on the surface. HMS Broadwater immediately launched a pattern of five depth charges. Although two jammed on the rails, the other three temporarily disabled the rudder controls and the electric motors, forcing the boat down from a depth of 45 metres to 70 m (230 ft). Although Broadwater then lost Asdic contact, HMS Abelia made contact 30 minutes later, and after dropping five depth charges reported oil on the surface at 08.03 hrs. She then dropped two patterns of five and eight depth charges at 08.34 and 08.43 hrs. It is also possible that some of the attacks carried out by USS Livermore and USS Decatur during that morning were against U-432. These attacks kept the U-boat submerged for the whole morning. On surfacing at 13.00 hrs, it was noticed that the contents of a fuel ballast tank had been lost, which would have betrayed their position through a trail of oil. Both compressors were also out of order, and the boat could only reach a speed of 12 knots (22kph) until repairs could be made and she was able to continue her patrol.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-432 did not suffer any casualties (we know of) until the time of her loss.
