Ok, so this may be borderline ASB, but just for $^*&s and giggles, your mission should you choose to except it is to make the Confederacy survive to at least 1940's or later. You can have it either through them winning the Civil War or by a possible peaceful succession (Yeah, I know how crazy it sounds).
So
If you can make the CSA make it to the 1940's one cookie
If you can make the CSA make it past the 1940's two cookies
You do either one as a "peaceful succession" you get two additional
And GO!
