Attacks on this boat and other events
21 Sep 1943
The boat was attacked by British Hudson V9161 (269 Sqn RAF/G, pilot F/Sgt E.J.L. Brame) SE of Iceland. On the first approach the port aileron was damaged by flak and 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 three depth charges dropped in the following low level attack, and then escaped by diving. (Sources: Franks/Zimmerman)
4 Oct 1943
Aircraft attack, aircraft shot down: British Liberator (120 Sqn RAF/V, pilot W/C R.M. Longmore, OBE)
11.38 hrs, the Denmark Strait, between Greenland and Iceland: the aircraft, escorting convoy ONS-19 was hit by flak on its first approach. Fires started in both starboard engines and the aircraft crashed, killing the crew of eight, which included the CO of 120 Squadron RAF. The depth charges overshot, causing only minor damage. One of U-539's crew was slightly wounded by strafing.(Sources: Franks/Zimmerman)
