Force H

Hello,

I am currently doing the campaign in which i was told to sink a battleship from Force H (It is only one because of the lite campaign mod). Now my question is: what do they mean with battleship. Today i sank a Kent heavy cruiser and i was expecting to have fulfilled the mission but that wasn't the case and now i haven't got a clue what else to sink. Because just about everything is smaller than a Kent heavy Cruiser.
