Need help in the battleship sinking mission
 

How the hell do I do that mission? In all the times i tried, the ship just power up the engines and run away, after I shot the torpedos! Also tried to shot under the max range of the torpedos.The periscope went up, the sight bar, stayed all green, solution and fired.After it, down periscope and went to the torpedo camera. The ship started to move.
Don´t know what to do!

Ship started to move ? You mean it was laying still as you shoot the torps ?

Shot one torpedo directly at it and one on a lead angle ahead of it :)

Yes, the ship is still in the water with 3 or 4 destroyers patrolling around it. I have both games, the German version that come first, and know I bought the English version; because of certain things I could not understand in game (do not speak German). I already did this mission on German version, and the ship was still all the time, even after I fired the torpedoes.
Now, I'm also using the u-boot kurt west mod, so I do not know if several ship behaviors was change.
I thought of that, but since the limited supply of torpedoes, I didn’t risk it. But a submerge night attack, in a stormy weather, how the hell those brits spotted my periscope and torpedoes, hum (little rant about the game, I know, I know...)?

Anyway, try the lead angle trick.
