Idea I had while looking into a CSA timeline. Traditional set-up of Confederate tactical superiority sees the Union routed early (191 set-up), Washington is captured after a siege, Kentucky joins the South etc. and finally an Anglo-French delegation step in to secure peace.
Washington DC was a very important place in the hearts of both sides, and in this set-up it is ultimately political rather than military defeat that sees the Union give in. As such I can't imagine the North being too keen on handing over the city, it would become a sticking point in peace negotiations. As such I'm wondering how likely a Free City would be accepted by the parties, overseen by Union and Confederate officials as a neutral bastion on the border.
