To play devil's advocate here (or maybe just stir up trouble ....While the result seems a bit out of whack at first blush, here's my take on it:
The submarine attacks the routine (automatic?) convoy. He is able to make the contact because the sub has a highly skilled, aggressive commander (more likely if this was a PBEM/human Japanese player). He hits his target, and the escort counterattacks. Two hits with a depth charge is not enough to sink a sub in this game. I've had subs take 4-5 hits and not be forced to the surface. I do think subs are a little too sturdy, but it is what it is. However, in this case, the sub comes up, but not critically damaged or nearly sinking. Once on the surface, the sub starts its diesel engines and finds itself with superior maneuverability vs. AKs, superior firepower (torps and 5.5 inch guns vs. 3 inch), and superior gunnery. The convoy ship commanders are probably all bottom-of the barrel if set up by the automatic system, or not specifically assigned by the Allied player. What is a highly skilled, aggressive sub commander to do?
The answer is probably not "run away." As always, there are a lot of specifics we don't know about the battle, but I think there's a lot of room for this to be a reasonable result.
Any other thoughts on this?
Those are my thoughts as well. Not necessarily realistic, but given what I know about the game engine (and especially the commanders point that you brought up), I don't think the result is entirely unreasonable.
If any kind of heavier escort had been present (say, a DD), with the changes in commander quality and sheer weight of armament that entails, the sub would've been sunk on the surface in pretty short order.
