It was my first patrol on stock game, with a VIIB in September 1939. I had just decimated a barely escorted convoy at AL39, leaving only the American ships alive. I was heading for home, at 1024 TC.
Then I 'gracefully parked' at
St. Kilda Island.
I don't know how I managed to return to Kiel with 4% H.I. Must have been Poseidon.
