Attacks on U-107 during this patrol
7 Jan 1944
Between 00.08 and 01.20 hours, inbound in the Bay of Biscay, U-107 was attacked four times by aircraft identified as Liberators, replying each time with AA fire, while nearby, U-621 fired on an aircraft without herself being attacked at 00.10 hours. All bombs fell astern of U-107, causing no damage.
Three aircraft probably 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 flak hits to the bomb bay and the control surfaces. (Sources: Franks/Zimmerman)
