(All times are zone -1)
1540 hours - HE was reported bearing 290°.

1620 hours - Sighted a four-engined aircraft overhead. It was identified as being most likely a German Focke-Wulf aircraft. Meanwhile the HE had ceased. Up to this moment the HE had been thought to be that of a trawler but it was now considered that it could be a submarine that had dived upon the approach of the aircraft.

1645 hours - Strong HE was now picked up again bearing 300°. Graph was maneuvered onto a firing course.

1652 hours - The conning tower of the enemy was seen for the first time. Started attack.

(All times are zone -2)
1654 hours - Sighted aircraft, could not be identified but it was quite big. Dived.

1737 hours - Surfaced.

1755 hours - Sighted torpedo tracks to Starboard. Looked like one torpedo ran on the surface. Turned hard to Port. Four tracks were seen, all missed astern. Four end of run detonations were heard. Sent report to B.d.U. and cleared the area zig-zagging. (10)
