[singing mode on]What a difference... a (gun) day makeees[/singing mode off]
After sinking no more than a lone C2 in the II subs, I had a blast with my first VIIB. 40 Tons and munition to spare, but the weather was awful and I didn't think a real commander would stay without torpedoes, so I ended the patrol.
I was leaving the E coast of England with a single astern torp left... rough seas... C2 in sight, darn!
I bet on the single shot magnetic pistol wonder and pray... "Torpedo Missed Sir!"... but wait, explosion right under its soft spot! Enemy target destroyed! Yesss!!
Having loads of fun, and still in 1940!
