Sweden Loses -- ie doesn't gain anything.
I know you would need some kind of Danish POD involving switching sides, at the rite moment, or some such.
But I was more interested in the effects come mid 1800's and German Unification, and the like.
However a 1800's Swedish/ Danish war over Norway sound interesting, ?Any Ideas when, or who wins?
But does the Swedes keep Pomern and Wismar? If so you have a more interesting 1848 and then the times following Bismarck's accession to power - he'd have to get rid of three foreign powers instead of two to establish the German Empire.
Bad thing 1848 is that Pomern is a neighbour of Prussia itself.
BTW 1815 Prussia wanted Pomern - so?
I guess Sweden isn't going to wage war on Russia!
But Denmark-Norway that is another matter. And as v.Adler says Bernadotte is going to need it quickly.
So 1816 at the latest is my guess. Bernadotte had the army ready to move into Norway 1814 and did - so only a couple of years. The feeling of defeat would be too great in Sweden and as already said everbody wanted a go at Russia to get Finland.
How will the war go?
The Swedes had 11 ships of the line and 10 frigates but I read somewhere that only four of each were serviceable in 1814 - perhaps they just didn't fit out more.
They would probably be able to field an army no smaller than the one sent to Germany of 30000. Probably much more.
The Danish navy still suffered from the loss of 1807 and had only 2 ships of the line and 2 frigates left. Another frigate would join the navy 1815.
The Naval war seems a foregone conclusion but it really depends on the numbers brought into service by the Swedes. Also the navigation of the Danish waters is a bonus to the Danes as its numerous rowing gunboats, yes they had been quite useful even managed to defeat a British ship of the line!
So the Danes will not want to meet the Swedes on the Baltic but try to lure them into shallow waters to pull their teeth.
The land war is another story.
The Norwegian army numbered some 35000 and perhaps a few thoudsand Danish troops could be transported north but it would depend on the ability of the Danish-Norwegian navy to block the straits.
These troops would fight the Swedes but the Norwegians had suffered from famine during the years of 1807-14 when the Danish-Norwegian navy couldn't convoy the cereal ships for Norway.
The only real threat would be by Denmark threatening to invade Scania. That would tie up Swedish forces.
Most probably part or all of Norway would have to be cede except if Britain raise her voice at Bernadotte!
