Thanks
I lost my second boat when sneaking big convoy. DD was like pitbull and I make wrong move, results you know
Anyway, I wonder did I delete this career (started 9/1939), 4th patrol, 12/1939 and managed go through Der Kanal... sonar informed some merchants and many warships.
Rig silent days and surface nights, cold sweat still running
Well, it's like flightsims -> practise, practise and practise
