Figuring that since I have this huge army and no infamy I may as well flaunt it, I snagged one of my tiny neighbors to the south and tributary-ed one of their neighbors that helped defend them.
The Ottomans promptly took a second swing at me, so I set up counter-war-goals to make them give up claims on another border state, re-up their reparations, and completely liberate Cyprus. Tripolitania backed them, so they're next on my list once my infamy decays. Spain eventually joined in too, so I bought the French participation by promising them an Ottoman treaty port as a war goal. However, right as the war started France began the first of undoubtedly many revolutions and suddenly didn't have much to contribute at all, leaving me with the short straw in terms of manpower, barely.
Opening moves went well and I grabbed a tiny bit of land, but soon Spain landed about as many brigades as my entire army in Ottoman territory, and better equipped as well. I switched my offensive army to holding the line and prayed for the French situation to wrap up in a timely fashion. (Hmmm, but looking at it Spain has a bunch of brigades but they're only at 20% strength? That seems like a failure of the AI... switching back to attack mode)
My new (and culturally discriminated against) conquests to the south opportunistically took up arms against me to, the suppression of which initially rated higher than "trivial"... but only barely. Unfortunately, my tributary joined them and this increased the force to a quantity that would be manageable if I weren't fighting a larger foe but is significantly inconvenient while I am. Worse, they have claims to the territory that is uprising and I think they might be able to unify it into a larger state if they win. My land grab is starting to look a bit ill-advised. Trusting in the undermanning of the Spanish divisions defending the Ottoman empire, I pulled my main army down to crush that.
Conveniently, at this point I look over and see that the French have unified into a new republic and are putting pressure on the Spanish border, which doesn't bode well for the Spanish armies in the Ottoman recovering any times soon. As my main army marches down to crush the uprising, my tributary decides that discretion is the better part of valor and backs out of the diplomatic play. The enemy ranks are larger than expected and my smaller anti-uprising force starts slowly losing ground, but with my main army on the way, Spain capitulating, and France on the way to invade the Ottoman the outcome is inevitable.
In an odd note Spain- gracious in defeat- celebrates their withdrawal from the war and war reparations to us by guaranteeing our independence. Curious, but the more the merrier. Cyprus, meanwhile, seems not only disinclined to shower me with gifts or accept protectorate status after I liberated them but immediately adopts a "belligerent" attitude towards me even though I've also guaranteed their newly acquired independence. Oh well- see if I help them again. At least Turkey's down a state.
