I always start my careers in 1939 and am generally dead by 1941 so this kaleun is a bit surprised to be sailing the North Atlantic in mid 1942. The merchies have started tooling up for action. No surprise there but they're decked out like cruisers!
I fired a torp at a solitary whale factory ship and then surfaced to finish him off and got the snot kicked out of me! There were gunners practically hanging off the masts. The Liberty ship I'm stalking now has got a hole in its hull but it also has 3 guns up front, 3 at the stern and 4 machine guns up top!!!!! The Bismark didn't have that kind of firepower!
My 'one torpedo one ship' strategy is gonna have to change and BdU is not gonna be happy
