I've got one from a few months ago (thankfully I can review the Twitch VoD and tell it exactly).
So it's 1946. Canada (me) and Germany have been at war, with Canada fighting in Europe due to their (my) ownership of Iceland. The war went pretty badly early on, with multiple Canadian carriers lost to fires, but it's been starting to turn around.
A cruiser battle off of Iceland is accepted. It's dusk. I get 2 light cruisers, one Brooklyn-alike cruiser (Camrose) and an Atlanta-alike cruiser lacking the side turrets (Kamloops), plus a set of destroyers.
Germany gets 2 heavy cruisers.
The cruisers involved:
(I just realized this is the first time any of the cruisers see combat)
Camrose leads Kamloops, while Scharnhorst, one of Germany's newest cruisers, leads the older Hansa.
The battle initially starts with the Canadian cruisers crossing the T of the German cruisers, but the German cruisers turn broadside before that matters at all, turning this into a typical broadside engagement.
The early minutes of the battle have a few hits landed by both sides, slightly favoring the Germans. Then one minute Camrose lands 6 hits with Kamloops and 2 destroyers each landing 1 hit to no German reply. The next minute Camrose lands another 4 (and a 4" hit) with only 1 German shell as a reply. The battle is looking favorable.
And then Camrose explodes from a hit to her X turret. It was the 5th hit she had received the whole engagement.
So now it's Kamloops and 5 destroyers against 2 enemy heavy cruisers, with Scharnhorst a bit damaged (and with a jammed rudder) from all the hits from Camrose. Can this little light cruiser with 12 5" guns as main armament beat 2 heavy cruisers virtually alone?
The answer is yes.
Hansa splits off while Kamloops sails broadside to and ahead of Scharnhorst as night falls. All of the torpedoes launched from the destroyers miss. But the guns from Kamloops and the destroyers don't, hitting the ship dozens of times for no reply. Mostly because Scharnhorst's 2 forward turrets are both destroyed and both of her aft turrets are disabled. And then her X turret is knocked out as well, before Kamloops crosses Scharnhorst's bow. Still though, no torpedoes can hit the crippled cruiser which can't even turn, as 2 salvoes from the DD Rosemere and a torpedo from Kamloops catch Scharnhorst in a crossfire which she just sails through unscathed. Scharnhorst then suddenly repairs her rudder, dodging 2 more salvoes of torpedoes before coming to a stop, on fire, with a torpedo from the DD Boucherville finishing her off.
Hansa is still off in the distance, just barely within spotting distance at this point in time after having been observed on radar while Scharnhorst was receiving her 5" shell spam beatdown.
Kamloops charges in while the destroyers fall behind a bit. Kamloops is giving a lot of 5" hits, but is in turn taking multiple 8" shell hits which are doing significant damage to her machinery and ability to float. Then Kamloops fires a torpedo salvo of 3, actually landing a hit.
Both ships keep shooting each other, with neither side particularly winning the contest, even though the Canadian destroyers are starting to get involved. Then Hansa's rudder jams, and at that point every hit landed is from a Canadian shell. Kamloops is in a stable condition, albiet heavily damaged, and still has much of her armament available, while Hansa is burning and has all of her main guns disabled or destroyed. Hansa sails through a torpedo salvo from a destroyer without being hit, but it doesn't matter, as all the gunfire striking her eventually causes her to sink (or burn down, not sure), and the "Germany has no ships at sea! The scenario is over!" message pops up.
Ok then, that was good, we sank 2 heavy cruisers and lost... 2 light cruisers?
Yeah, after achieving her greatest victory by effectively solo-ing 2 heavy cruisers in a cruiser armed with only 12 5" guns, Kamloops was lost...
Due to a fire...
Which burned her down after the battle...
Which was under control when Hansa was sunk.
So yeah, that's probably the goofiest battle I've had. To recap, I was facing 2 heavy cruisers with a strong light cruiser and an AA cruiser, plus a group of destroyers. The powerful light cruiser blew up early in the fight, and then the AA cruiser and destroyers managed to win a gunfight against the heavy cruisers, with the destroyer's torpedoes having little impact on the fight, and then after winning the AA cruiser was still lost anyways due to her desire to impersonate a Canadian fleet carrier which had just been struck by a 300 lb bomb.
Don't worry, Kamloops had a new cruiser named after her once the war completed.
