WI:Habsburgs fight alongside with sigismund III Against Swedish Separatists

[Math]

Well if the Habsburgs fearing that Sweden would fall back into the hands of a Protestant king and they intervene in war for deposition of sigismund III in sweden(https://en.m.wikipedia.org/wiki/War_against_Sigismund)
on the sigismund side

If the Habsburgs can help sigismund III win what would the butterflies be

Sigismund was a fanatical Catholic He is an admirer of the Habsburgs and considered a Catholic counter-reform league with Austria(This led to problems against several tycoons in the commonwealth who were afraid and opposed to a Habsburg hegemony), With him holding the throne in Sweden it could prevent Sweden from entering the Thirty Years War in the side Protestant?

And what would be the effects of a Sweden that does not fight alongside with the Protestants in the Thirty Years War?

I have a hard time seeing Sigismund win - his ability to project power into Sweden is not really affected by Habsburg help. Karl's army was twice as big as Sigismund's at the Battle of Stångebro 1598, which proved to be the decisive battle of the war - the nobility and burghers pretty much abandoned Sigismund as a lost cause after that, and the rest of the war was mostly Duke Karl dealing with internal opposition that fought in the name of Sigismund.

Neither the Habsburgs nor the Poles had the ability to land troops in Sweden - the Poles might be able to attack Swedish Estonia, but that is about it. Sweden had a decent navy, neither Poland nor the Habsburgs had that. This is before the Duke of Courland started colonial ventures and built an impressive navy.

Well the Austrian Habsburgs could enlist the help of the Spanish Navy from their cousins spanish habsburgs? I don't know much about the Swedish Navy at that time but the Spanish Navy must be superior(Remembering that during this period Spain was in union with Portugal which means that it can also use a little of the Portuguese Navy) If the Austrians convince Philip II They could have the Navy to face the Swedes,

Sigismund wasn't Catholic fanatic, that is propaganda spread by his opponent in both Sweden and PLC, it was rather Charles, who was Protestant fanatic. Sigismund hired Protestants as his children's tutors, his own sister Anna, whom he very liked, was Lutheran. Sigismund was personaly devout, but not fanatic.

Jan You seem to know a lot about Poland , It is possible for sigismund to keep the throne with Habsburg support?, And what would he do if he managed to keep a throne?

I read that he tried to enter the Thirty Years War on the Catholic side, but the sejm Did not authorize intervention of the commonwealth If the Habsburgs would help him keep the Swedish throne,he could convince the Sejm Authorizing participation of commonwealth in the thirty years War?

Do you think the English and Dutch (which had stronger navies than Sweden) would let the Spanish fleet sail through their waters to attack someone else? The Dutch and English were at war with Spain 1585-1604, so the Spanish fleet and any supply ship for them will hardly be able to sail through the English channel and the North Sea unmolested. And that is not counting Denmark and Lübeck, which both had powerful navies and no interest in letting the Habsburgs establish a naval presence in the North Sea or the Baltic Sea. And where would the Spanish navy base itself for operations in the Baltic Sea? Polish control of Königsberg and Danzig are tenous at best in this era.

1566 the Swedish navy had 68 purpose-built ships of war, of which the largest (HMS Mars) had 90 guns. The Swedish navy declined somewhat during the era after Erik XIV was deposed, until Gustav II Adolf revived it, but it is still strong enough to put up some serious resistance. The Courlandish navy is still 20 years away at this point.

I think your missing the point here if you want Sigismund to win you need to change things in Sweden not Poland. Poland can have the support of the Habsburgs and the French but if they can't get to Sweden in the first place the support is useless.

Sigismund's humane nature, which he inherited from his mother, was obstacle. If he was more like father then Charles would be food for worms before he has occassion to depose nephew from the throne.
