Well, this was probably the shortest ACW in alternate history, as the USA surrendered after a couple of months since its armies were having no effect - I went back, regrouped, launched an attack with 32k against 20k and still lost. With no reinforcements in prospect the only other alternative was bankruptcy and STILL LOSING, so I accepted the first CSA peace offer that came my way
In the 30 years since this, leading up to the early 1890s the USA has become an armed camp with potential enemies on all sides in Britain, the CSA and Mexico. I still own Texas (which includes the bit I nicked from Mexico right at the start) but it is sundered from the rest of the Union by Confederate territory. Most of the USA is covered in level 4 forts, with 50k armies stationed strategically arround the place, with fleets of monitors for coastal defence and fleets of ironclads for more power projection. I've built both great canals, and have started to colonise some islands in the Pacific, plus Somaliland (once my railway-obsessed capitalists finally let me build a naval base at Suez)
Foreign policy has largely been confined to making allies in S America, as my only ventures into war have been disastrous, both to try and bolster Egypt against Ottoman aggression, but in the first war I sent my army to land in what looked a safe area but by the time it got there it disembarked in the middle of 3 larger Ottoman armies which then chased it across Egypt and destroyed it before the pyramids! The second time my army was somehow attacked by over 100k Ottomans and wiped out. Both times I also lost the majority of ships sent to the Mediterranean as Suez had no naval base, this included 20 monitors which sank in the Adriatic!
I can't afford large expeditionary forces since if I denude one of my borders to send the troops overseas I'm pretty sure the relevant enemy will descend on me. Currently my 30k expeditionary army is in Colombia helping them put down a revolution, since they've had 2 before and I got fed up of rebuilding my influence, but reckoned any attempt to turn it around and attack Colombia for the rest of Panama province would get Britain declaring war on me.
4th in everything, but this adds up amusingly to 5th in the world. Not sure what to do now, colonisation looking to be the only way forward...
