The then Kingdom of Denmark-Norway had a war with him called the Kalmar War in 1611-1613. Sweden wanted taxation rights in the north of Norway, as well as access to the sea.
The war started when Sweden was still under the rule of Karl IX, who demanded tax from the "sea-samii" people in Eastern Finnmark (Finnmark is Norways most northern county), he built churches and consructed forts in the area.
He gave priveleges to Gothenburg to bypass Danish taxes at Øresund. The Danes where supperior at sea, and took Kalmar after hard fighting, and continued to take Alvsborg, and Gothenburg. The plan was to that conscripted soldiers from Norway was to attack Sweden, but the untrained, ill equipped farmers that they really where, where not willing or usable. And their contrbution was of no consequense.
But the Norwegian farmers did stop a unit of Swedish mercenaries led by the Scottish Leutenant Cournal Alexander Ramsey, who was captured and taken to Copenhagen. His unit was completely annihilated. Of 350 men, only 18 survived.
Another Swedish Unit, led by Cournal Munchaven marched trough Stjordalen (in Norway) and arrived complete to Harjedalen, but had no impact on the war.
Gustav II Adolf, took the crown of Sweden after his father in 1611, and took Kristianopel by Kalmarsund. But when he recieved no help from mercenaries, and Danish troops marched in from Blekinge towards Kalmar, and from Halland towards Jonkping, treathening his position, he gave up and peace was settled in Knared on the 20th January 1613. Sweden relented their claims in Finnmark, else the Borders remained the same. Finnamrk was secured for Norway.
Sweden had to pay 1 million "riksdaler" (the currency of the time) in war retributions, with the town of Alvsborg as security, further they had to decline on giving privileges to Gothenburg.
In Norway the farmers where punished for pasitivity, and a Norwegian land and sea deffence was established within a few years...
My comment: Well, the farmers of Norway, was our army back then. They would fight, but not for a Danish king in a foreign country...defending the homeland against a plundering invader was a comepletely different story.
Anyway, I think that was our only encounter with the famous Gustav II Adolf. I guess we were lucky he was distracted elsewhere for the rest of his reign. We fought 10 wars against those swedes in that period...10 - 0 to Norway...except they came 11 times... :evil:
