I don't think I have ever made it throught the war, about mid 43 is my limit, I tend to get to cocky and then caught out. I have a brand new tactic though that seems to work quite well, basically it works like this, cowardice
So Oct 43 and I'm in with a chance. Now I only pick off the stragglers and the lame, blast them with torps and get home. If it's raining and visibility is down, say 900 meters, wait it out. load up with homing torps if you have the renown, especially the rear tubes for the flowers, mine a type VIIC, tweaked to 300 meters depth with GWX3.0 on boarb with FM Interiors, brilliant.
