Attacks on this day


U-441. This flak boat was strafed by three British Beaufighters from 248 Sqdn RAF in the Bay of Biscay. Ten men died and 13 were wounded, including all officers except the ship's doctor. Dr Paul Pfaffinger took over command from Kplt von Hartmann, treated the wounded and brought the boat back to Brest. He was subsequently awarded the German Cross in Gold. This action led to the abandonment of the flak boat experiment, and all the boats involved were returned to their original armament configuration. (Franks/Zimmerman)

U-732. Two American OS2U Kingfisher reconnaissance aircraft attacked the boat in the Gulf of Gonave, Haiti, causing minor damage. (Blair, vol 2, page 364)

U-185. On 12 July 1943 some 90 miles (145 km) off Recife, Brazil, U-185 was attacked by a US Liberator aircraft (VB-107 USN/B-7). Although the bomber crew believed they had crippled the boat, U-185s radio report stated the attack caused only minor damage.
