Attacks on U-107 during this patrol
4 Jan 1944
At 19.34 hours, the inbound boat fought off a four-engined aircraft in the Bay of Biscay. No bombs dropped, one crewman slightly wounded by strafing. (Sources: Ritschel)
7 Jan 1944
Between 00.08 and 01.20 hours, the inbound boat was attacked four times by aircraft identified as Liberators and replied each time with its AA guns, while the nearby U-621 fired on an aircraft without being attacked herself at 00.10 hours. All bombs missed U-107 astern and the boat suffered no damage.
Probably three aircraft attacked U-107 that night, a Canadian Wellington (407 Sqdn RCAF/J, pilot F/O Jordan), a British Halifax (502 Sqdn RAF/F, pilot F/O J.H. Spurgeon) and a second Halifax (53 Sqdn RAF, pilot F/L E.B.A. Le Maistre, RCAF) which was badly damaged by AA fire after hits in the bomb bay and the control surfaces. (Sources: Franks/Zimmerman)
