Attacks on this day


U-606. Aircraft attack, aircraft shot down:
Norwegian Catalina Mk.III FP525 (330 Sqdn RAF/Z, pilot Lt C.J.A. Stansberg)

11.14 hrs, NE of Jan Mayen Island: the boat was attacked by the Catalina astern of convoy QP 14. Accurate flak during the attack run caused four depth charges to fall wide, causing only minor damage to the boat. With two wounded and damage to one engine and the petrol tanks, the Catalina made a forced landing near the convoy. The crew were rescued by HMS Marne.



U-539. The boat was attacked by British Hudson V9161 (269 Sqn RAF/G, pilot F/Sgt E.J.L. Brame) SE of Iceland. On the first approach the port aileron was damaged by flak and the pilot decided to drop two 100lb A/S bombs from a higher altitude to force the boat to dive. The bombs fell close, but U-539 stayed on the surface, evaded the three depth charges dropped in the following low level attack, and then escaped by diving. (Franks/Zimmerman)

U-386. U-386 had to break off an attack on convoy ON 202 in mid Atlantic after being heavily depth charged. (Blair, vol 2, page 423)
