Sure. Sweden was pretty much bankrupt after the minority government of Charles XI.You forgot that Sweden and France concluded an alliance in 1672 , with France promising 400,000 riksdalers of subsidies in peace time, to be raised to 600,000 in war time, for Sweden maintaining a 16,000 men strong army in her German dominions.
By September 1674, Sweden had enlarged her army to 22,000 men after France had increased the subsidies to 900,000 riksdalers, which she threatened to withdraw if Sweden was not using this army
French were financing Swedish. Likewise, during Thirty Years War it were also the French who were providing financial support to Gustav II.
Sweden didn't perform well in terms of inflecting serious damage to Brandenburg - Prussia and distracting it. So, Swedish weren't even able to do that good of a job on their end. Luckily, France was triumphant in their conflict and helped Sweden.
Someone had made off with the money, and it hadn't been spent on the army, that's for sure. It's possibly the worst prepared war in Swedish history (alongside "The Hats' Russian War" in the 18th c.)
So it's certainly one of the more ignominious episodes in Swedish military history. Good thing for the Brandenburgers too. Gave them something to hype and mythologize.
Charles XI first had to win the war with the Danes, and then confront the Swedish nobles to get the country back in order. He pretty much saved Sweden.
