Operation Weserübung
 

It's probably just me but how the ******* can this be done? I don't nearly have enough torpedoes to sink 5 ships in 1 patrol, let alone if one is a battleship.... And you don't have time to go back to base to refill.....

And if you fail the mission? Can you return to base and complete the campaign? I tried it once but nothing seemed to happen....

Just finished it tho, went from march 1st untill march 8th. Found four merchants and queen elizabeth in that shaded area. Elizabeth as well counted as a 5th ship. It was really easy mission for me. I used following tactic...while surfaced, i patrol area (going just simply straight ahead, or to the sides) at max speed, x512-1024 for 50-100km, then drop to x16-32, speed to 0, submerge, and see what hydrophone guy has to say.
