Attacks on U-438 during this patrol

25 Aug 1942
At 07.05 hrs HNoMS Eglantine obtained a radar contact between her and HNoMS Montbretia on the starboard quarter of convoy ONS 122 and opened fire with the 4in gun on sighting U-438 through fog five minutes later. After U-438 dived the corvette intended to attack with ten depth charges, but only dropped two because both traps jammed and six throwers misfired. They held contact and delivered a second attack, but with only one depth charge because the launchers were still out of action. At 07.26 hrs a third and final attack was made with five depth charges before the ship returned to the convoy. The U-boat had dived to 180m (590 ft), but the depth charges caused a leak in the bow compartment that could not be stopped, which forced U-438 to surface shortly afterwards. Despite being unable to dive, they escaped in the fog, and six hours later had managed to repair the damage, but were ordered to return to base because their fuel supplies were low.
