Thanks for the feedback, I'll do some testing with groups that have only a single asset and multiple destroyers. That seems to be the common theme here.
As for sitting on the bottom still in shallow water, I'm not so sure that's a good idea, as they start from your last known position to try to re-acquire you, so if they have depth charged you and you sit in the same spot, they will find you again fairly easily. I have an idea about that though. I think your best chance against a single asset convoy is to start planning your escape before you attack and be on your way out before it hits home. I'm not sure what the 'correct' procedure they'd follow is, but I should think they'd be pretty annoyed if you sank the only thing they were protecting
.
Did you both attack at night, submerged?
Thanks again for the feedback, I want it to be a challenge, but not certain death, so I'll have a look at it. You did both survive for a few hours though, which is good
. Not sure how they managed to multiply - they must have called for re-inforcements. Keeping you down until you run out of air sounds fairly realistic, but maybe need to only happen when you run into a really well trainedd veteran group?
