Attacks on this boat

2 Mar 1943
The boat was attacked by an American Liberator aircraft (USAAF A/S-Sqdn 1 / E) with 5 bombs and suffered medium damages, but remained on patrol after repairs by the crew. (Sources: Rohwer)

24 Jul 1943
Near Madeira, Portugal, U-373 was attacked by Avenger and Wildcat aircraft from the escort carrier USS Santee on 24 July. The boat was damaged by a Fido homing torpedo hit killing 2 and wounding 7 men. The boat did not have to abort its mission. [Matrosenobergefreiter Franz Schulte, Matrosengefreiter Peter Regneri] (Sources: Blair, vol 2, page 393)

3 Jan 1944
The boat was attacked by British Wellington (Sqdn 612, pilot John B. Russell) which dropped depth charges. Another aircraft, this time a British B-24 Liberator (Sqdn 224, pilot Harold R. Facey) assisted and dropped 8 more depth charges at the boat. U-373 was heavily damaged and reached Brest on Jan 4. Upon reaching port 2 unexploded depth charges were found on the tower and the boat had to leave port to jettison them (an extremely dangerous business) which they successfully did. (Sources: Blair, vol 2, page 486)
