In the morning I was lined up again. Nothing but small fry left. The damaged heavies were missing. Clear with rough seas. Torpedoes exploding before reaching target. One Swan gave me three passes, dumped 26 DCs and left. With no good targets left, decided to backtrack found an 11,000 tonne stragler. One torpedo a few meters ahead of the superstructure made it explode. I headed home with 72,000 tonnes.
Will have to try this again with a larger convoy. This one dumped something like 400 ash cans on me. I think the swans might have been out of DCs. The Flower was missing on this last show. So, we have a failed experiment but decent tonnage, a short patrol and a Ritterkreuz.
