Yes, I finally did it! Roughly 32 to 2400 points against the Brit AI with 20 strategic cities taken and all but two objectives occupied as the Colonials in scenario #6, thanks to the postings of Markshot and others.
To make a long revolution short:
-- Abbreviate your invasion of Canada and don't send troops by land to Quebec (I later used the French fleet with Spanish troops to take this city via seige and shore bombardment). Instead, barricade Arnold in Montreal -- with a subordinate for when Benedict bucks the cause -- and Montgomery in St. John. This helps deflect/slow down the reinforcements from Canada.
-- Boston was/is the heart of the revolution, so even if you lose it, get it back quick as soon you can. Albany holds some important geography, so give priority to this strategic city even though it's not an objective.
-- Washington does better with leaner, meaner armies, otherwise he might stand and fight to the death (of your game).
-- Garrison towns near victory cities with single units/small armies (w/leaders having good defensive values) as they will impede the advance of the Brit AI which will stop to seige, even in winter (some czar said his two best generals were called January and February). Also, send any spare regular troops on a circuit through unoccupied enemy towns to change their allegiance, even if they are not victory cities.
-- Any battle you can walk away from is a good one; put your army into passive () posture and tuck them away in a safe city until replenished to fight again.
-- Artillery inside coastline strategic cities (NY, Boston, Philly, etc.) is very useful for fending-off fleet bombardments; often times the Brit fleet gets the worst of it and has to refit in port, taking it out of the game for a while. The Colonials can also use fleet bombardment for seige, esp. against southern victory cities that don't shoot back as much.
-- Take and hold remote objectives w/Continental armies as they don't disband like militias and leave you "holding the fort" w/o any troops! Also, let training officers lead garrison troops to train them, and then recycle these units to field commanders who can really use them.
-- Use Clark and his irregulars to burn Indian villages to the ground. Not very PC, but very effective in stopping those annoying raids.
-- Finally, the Brits can't be everywhere; disperse your forces and (slowly) take/retake every victory city you can until the AI has next to nothing left and can't generate local support/militias.
Toward the end of my game, the Brits lost the North and Deep South, so the AI concentrated its forces in South Central. I used the French to chase them out and almost caught Cornwallis, but he got away and turned-up near Boston where he and GW had some interestings fireworks just before the end of the game.
