Have conducted 3 port raids, all in late 1939.
First in Dover, located a war ship which could be hit from out of the port, so fired 3 torpedoes without really entering the port, after its sunk, identified it's a Southampton class cruiser. BTW: It seems ships moored in port often cannot be identified as a target, even after you get very close to them, wonder why.
Then went across the straight to Dunkirk, sneaked into the port at periscope depth, 1 knot. Sank one 20k ton Troop ship, one 10k ton tanker, and a destroyer, then returned by the same route.
After these success, I felt brave. So in next patrol I went straight to Scapa. Arrived it southeast entrance in twilight, then 1 knot, dived as deep as possible and at last made it in several (game) hours. However, there were no principal ships, not even a cruiser... only 1 destroyer and several small merchant ships, ahh... And I failed to made it out, thus ended my first career.
