U-103. 00.05 hrs, Bay of Biscay, outbound: Wellington bomber M for Mother from 172 Sqn RAF located U-103 on radar and made a Leigh Light attack, but the boat was warned by the radar detector, and dived in time to evade six depth charges which exploded harmlessly ahead of her. The Wellington circled the area and then approached a second radar contact which proved to be U-566, left unable to dive by an earlier air attack. The aircraft had no depth charges left and returned to base after an exchange of gunfire. (KTBs/ADM 199-1784)
