after i got a brand new Type XXI, i decided to have a crack at the task force coming home after operation tungsten. so i waited there in ambush, and managet to sink HMS Duke Of York, HMS Illustrious and HMS Indefatigable. the las one with homing torps aimed for the HMS Anson, which sadly slipped away.
after getting the boat's precoius equipment badly mauled and running short on battery after the chase (i had to keep up with the damaged Indefatigable until she sank to be sure i got the sinking) i returned to base to find a letter on my desk adressed to Kapitänleutnant Martin that i've ben "promoted" to Oberleutnant Zur See!
long story short: I miss my rank
Edit: and does someone know why both my sonar operator and my radio-operator decided to spontaneously die after that! it was not any flooding issue, i think because i just had some other randoms put at their stations there, and everythin worked perfect...
