Attacks on U-432 during this patrol
17 Oct 1941
At 05.30 hours, the boat was sighted by HMS Broadwater on the port beam of convoy SC-48. The destroyer could not use its gun on the forecastle due to weather damage and the 4in gun on starboard jammed when firing a star shell, so they tried to ram U-432 which turned inside her turning radius and tried to escape at full speed on the surface but soon crash dived. HMS Broadwater immediately dropped a pattern of five depth charges on her but two jammed on the rails, still the remaining charges damaged the U-boat on a depth of 45 meters, temporarily disabling the rudder controls and the electric engines and causing the boat to sink involuntary to 70 meters.
While the destroyer did not pick up an Asdic contact, HMS Abelia was able to do so about 30 minutes later and reported oil on the surface after dropping five depth charges at 08.03 hours. Two more attacks were carried out by the corvette with five and eight depth charges at 08.34 and 08.43 hours respectively. It is also possible that some of the attacks reported by USS Livermore and USS Decatur during that morning were ineffectively carried out on U-432. These attacks kept the U-boat submerged the whole morning and when surfacing at 13.00 hours, they noticed that all fuel oil had been lost from a fuel ballast tank giving away their submerged position by the trail of oil. Furthermore both compressors were out of order and the U-boat could only reach a speed of 12 knots until the crew carried out repairs and U-432 was able to continue her patrol.
