So I was in a new campaign being run by my local club. Sort of a victory at sea style campaign, where history doesn't matter so much as the fun. The world was a bit like strange real, where nations having 100+ battleships wouldn't be out of place.
Anyway, my main battlefleet is composed of three Nassau, two Helgoland, one Kaiser and one Baden Battleships. These are supported by Armored Cruisers and Cruisers.
In my first match, I was up against this guy, who is like the living embodiment of the masterwork katana meme. He thinks that the Kongo's armour belt was made of glorious nippon steel folded 1000 times. Anyway, we set out the pieces for the match. My fleet's objective was to defend a port (this guy was trying to capture mine). Now he spent a lot of money buying a ton of expensive boats, where I wanted to be able to lose a ship and not be out of the Campaign. Anyway, he lays out this small but modern fleet of Japanese ships. Two Kongo's, and a Fuso, backed by Heavy Cruisers (which for japan are minibattleships).
I know he has a range advantage over a lot of my early dreadnaughts, so I park them in an area where he can't see them. I put my two modern BBs front and center, with a screen of cruisers.
This guy comes charging in, and for some reason doesn't exploit his range advantage, closing to 20,000 yards. I lose an armored cruiser almost immediately to a Kongo, but my battleships weather hits well. Then my Bayern scores a hit on the forward turret of the Fuso at about 10,000 yards. The shell penetrates, and a few lucky rolls later, the front of the Fuso detonates with the fury of 1000 suns. The GM comes over when he hears 'Oh for FUCKS SAKE" from Otakusperglord. Guy starts trying to blame the rules system, saying that there is no way that a WW1 battleship could hurt a WW2 BB.
GG DM smirks a bit, and says, "You know the Fuso was just a slap dash re-armouring of a WW1 era ship right?" Otakusperglord is in shock.
Then rest of my fleet appears.
