AI type VIIC attack convoy with gunfire at the same I was attacking submerged with torpedoes. There were also an IXB and another VIIC on the scene. December 6 1940 grid BF13
It is a pity that AI Uboats can not launch torpedoes.
From the same attack: Black Swan escort exchanging gunfire with a VIIC type uboat.
The whole thing turned out as a blood bath for the Uboats. All AI subs (2xVIIC + 1xIXB) were sunk by the escorts. At least I escaped and sunk 3 ships from that convoy for 15000 tons.
UPDATE:
This was the tactical situation during my escape run
