Attacks on this boat
21 Sep 1943
The boat was attacked by the British Hudson aircraft V9161 (269 Sqdn RAF/G, pilot Sgt E.J.L. Brame) southeast of Iceland. During the first approach the aircraft was hit by AA fire in the port aileron, so the pilot decided to drop two 100lb A/S bombs from a higher altitude to force the boat to dive. The bombs fell close but U-539 stayed on the surface, evaded the 3 depth charges that were dropped in the following low level attack and then escaped by crash-diving. (Sources: Franks/Zimmerman)
4 Oct 1943
Aircraft attack, aircraft shot down:British B-24 Liberator (120 Sqdn RAF/V, pilot W/C R.M. Longmore, OBE)
Around 11.38 hours, the boat was attacked by the Liberator which escorted the convoy ONS-19. AA fire hit the aircraft during the attack run, set both starboard engines on fire and caused it to crash, killing all 8 crewmen including the CO of the 120 Squadron RAF. The depth charges overshot and caused only minor damages to U-539 and a crewman was slightly wounded by strafing.
(Sources: Franks/Zimmerman)8 Oct 1943

Schnorchel-fitted U-boat
This boat was fitted with a Schnorchel underwater-breathing apparatus but the date of fitting or sailing date with the equipment is unknown. Read more about the Schnorchel and see list of fitted boats.
Men lost from U-boats
Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-539 did not suffer any casualties (we know of) until the time of her loss.
