Your challenge is to create a legit scenario in which the British Crown gets to keep the southern colonies (Virginia and down) and the remaining northern ones become somewhat of a militarized federal government, with the POD being in the later years of the war.
Bonus points if the north is led by Horatio Gates both as a General and a President.
Double bonus points if the south gets to keep some semblance of autonomy.
