Loads of fun so far in the Black Sea

. Quite a different experience so far.
The Type IID takes some getting used to, but I like her a lot.
10/5/42:
Third day of the patrol in the eastern part of the Black Sea, patrolling along the coast.
I run into a 3 ship convoy escorted by 2 Novik class destroyers. During the approach, the hydrophones pick up other warship sounds in the distance.
I torpedo the two lead freighters, one sunk and the other slowing down.
I feel I kicked over a hornets nest. I have the two Noviks up there and the two warship contacts have joined the fun. They turned out to be Uragan destroyer escorts.
They're all buzzing around up there dropping DC's on me, but they seem pretty inaccurate and I'm deep and slowly slipping away.
I even took a peak with external cam and there were a couple of Lend Lease Hurricanes buzzing around up there.
