Well done, Herr Kaleun
I think I attacked the same convoy last night (Dec 24/25 1939).
During three surface attacks on the same night I sank Ammunition ship, 2 Large Merchants, 2 Ore carriers and Medium cargo.
The first attack was the best. I fired 2 eels at Ammo ship (4km away) and 1 to Ore carrier 2 minutes later to achieve simultaneous impacts. Then I rushed on paralel course to attack the second Ore carrier. One minute later all 3 torpedoes hit their targets, and I was caught by multiple spotlights and under heavy gun fire. Zig zaging like crazy at flank speed, I reached the Ore carrier, fired and dived deep. It was hectic, but I escaped undamaged. All three ships sank.
