Snuck into Lock Ewe in really bad weather... you know the type. Heavy rain & fog. I dont' remember the waves being really bad, probably because I'm in a harbor (at least they modeled that). It was also at night, so visibility was horrible.
I sighted this tanker just at the edge of my view range. Fired off one torpedo and dropped the 'scope (I'm being careful, since it's my first time in a harbor. Don't wanna mess this up

).
Bang. No "torpedo impact" from the crew :hmm:.
Fire off torp #2. Bang. Again, no torpedo imact notification.
#3. Bang.
#4. Bang.
Got out the external camera, then moved closer to the tanker. Hidden by the darkness and bad weather was one of those concrete docks.
I gave up and went back to port.
