Aircraft attack, aircraft shot down: British Liberator Mk.V BZ764 (120 Sqdn RAF/B, pilot F/L Harold F. Kerrigan, RCAF)

The aircraft had located U-737 with radar west of the Lofoten Islands but was hit by AA fire during the initial approach, setting the right outer engine on fire. Nevertheless six depth charges were dropped on the crash-diving U-boat that detonated as close as 10 meters, forcing it to resurface immediately. The Liberator attacked again, but sustained several hits in the intense AA fire - one round hit the nose wounding both navigators and disabling the bomb sight and release gear, so no more depth charges could be dropped. The aircrew managed to put out the fire and jettisoned the remaining weapons. One of the wounded navigators led the aircraft to Skitten, Scotland where the Liberator made a belly landing on two engines and was written off. The pilot was later awarded the DSO and the navigator the DFC for their actions. The damages forced the U-boat to abort the patrol.
