Attacks on U-231 during this patrol
22 Apr 1943
03.00 hrs, SE of Iceland: a British Catalina flying boat (190 Sqn RAF/T) strafed U-231 and dropped two bombs. The boat was undamaged, but one man was lost overboard. [Obersteuermann Walter Krause]
At 12.29 hrs, a second Catalina (190 Sqn RAF/E) dropped four bombs, this time with no effect.
23 Apr 1943
An attack by an unidentified aircraft left the boat with a flooded conning tower. The boat survived to reach France on May 31, after another unidentified aircraft attack on the way. (Sources: Blair, vol 2, page 335)
21 May 1943
Late evening, mid Atlantic in the vicinity of convoy
ON 184: a bomb from an American Avenger aircraft (VC-9 USN, pilot Lt Cdr Drane) from escort carrier USS Bogue (CVE 9) left the boat with a leak in the stern trimming tank. Chlorine gas from the aft battery compartment forced U-231 to return to base. Because both radio transmitters were also damaged, the boat did not respond to calls from BdU, and was supposed lost for a few days until U-305 reported her situation.
