Attacks on this boat and other events

6 Aug 1942
17.41 hrs, Bay of Biscay: A British Whitley bomber (502 Sqn RAF/V) dropped six depth charges. No damage.

6 Apr 1943
Severe damage from four depth charges dropped by a British B-24 Liberator bomber (120 Sqn RAF/E, pilot F/O J.K. Moffat) SW of Iceland forced U-594 to return to base. (Sources: Kenneth Wynn)

27 May 1943
21.50 hrs, vicinity of convoy SL 129: the boat was attacked by a British B-24 Liberator bomber (224 Sqn RAF/T, pilot F/S J.S. Edwards). The aircraft (misidentified as a Lancaster) had to abandon its first attack as the depth charges failed to release. Flak damaged the the inner port engine and nose. U-594 dived and escaped unscathed after six depth charges overshot astern in a second attack. (Sources: Franks/Zimmerman)

28 May 1943
15.30 hrs, Atlantic, W of Biscay, outbound: A British Halifax aircraft (502 Sqn RAF/H, pilot F/O A.J. Davey) located U-594 and exchanged gunfire: both claimed hits, but none were scored. U-594 then dived before the aircraft (misidentified as a Lancaster) could get into position for a bomb run, and the 600lb A/S bomb it subsequently dropped into the swirl exploded without result. (Sources: Franks/Zimmerman)

4 Jun 1943
The boat was attacked with rockets by a British Hudson aircraft (48 Sqn RAF/F) west of Gibraltar. This attack was formerly credited with the destruction of U-594, but it must have escaped with unknown damage only to be sunk by another Hudson from the same Squadron the next day. (Sources: Axel Niestlé & Eric Zimmerman)
