1637 (e)

(e) 45° 28'N, 9° 31'W
At 1637 hours, Whitley 'J' (EB399) of 10 Squadron sighted a submarine on a SW (outbound) course. The bomber attacked from the starboard beam of the submarine, releasing a stick of six depth charges from 75 feet. The rear gunner saw the stick undershoot, exploding well short. Another aircraft was now observed approaching and carrying out an attack during which it was observed to crash in flames.

This aircraft was Whitley 'L' (LA814) of the same squadron, piloted by Flight Sergeant H. Martin. It attacked at 1640 hours and was witnessed by bomber 'J' and three Halifaxes of 58 Squadron to approach from a low height and release a stick of six depth charges as the U-boat turned to port. The stick was observed by 'J' to slightly undershoot, the last depth charge falling just short of the U-boat's stern. Though no flak was observed from the submarine, the Whitley was seen to be trailing smoke following the attack. It caught fire, crashing into the sea. There were no survivors of the six man crew. The submarine then dived apparently normally.

Could this have been Barbarigo? Was she perhaps mortally wounded? She disappeared without a trace. T.V. Umberto De Julio, five officers and forty-seven ratings were missing.
