I did some crazy things in my careers and sometimes even with sucess.....someting like surfacing about 1000 meters away from a destroyer and firing manually at it....after 5 or 6 hits it exploded and went down....which I havent expected myself....after this the whole convoi was mine.
In early war situations with unarmed merchants, if there is only one DD Escort, I normally give the escort one torpedo, surface and have fun with the deck gun....
another crazy thing was chasing a Nelson-Class Battleship with a Type II U-Boat....It survived the first salvo of 3 Torpedoes and I just wasnt willing to let it get away with this. Submerged my boat was too slow to keep up with the ship, so I surfaced about 3000 meters behind the battleship and went to flank speed. At day in bright sunshine, thx to my small silhuette only the destroyer-sized secondary guns of the ship hit me a few times and I was able to close up to about 1500 meters. At this time my next torp was loaded and I took my shot with magnetic detonator (more an act of desperation)
With a chance of 1:1000 it hit the screws of the battleship, destroying 3 of them and bringing it down to about 3 knots. Finally, I dived to periscope depth again with a badly shot up u-boat. I fired my last torpedo on the side of the ship where my first three had hit it, it capsized and went down 5 minutes afterwards.....
SH3 Commander told me after this patrol my hull integrity was about 15 %, but hey, the Nelson was down.
