I've been playing a lot as US in 1776 full campaign and wanted to throw a few strategy observations out to see if any of them stick:
1) Holding Philladelphia is absolutely critical to US. This makes a great spot to retreat to in the winter and strike out from in the fighting months. I've never lost Philly against the AI but I've had some very close, epic battles between the Continental Army and very large Brittish forces and I think losing there would have cost me the war.
2) In addition, its key to hold either New York or Albany, prefferably New York. Both of these cities have a huge impact on mobility because they lie at the 2 easiest places to cross the Hudson which acts as a critical geographic feature in this area.
3) Once the French arrive (if they don't you are doomed!), the area between New York and Boston should be first priority. Once you control the land from Philly to Boston, you can pretty much strike in any direction needes as long as you don't lose that area. This is the area with the biggest cities and the most civilized regions. Transportation and logistics are much easier here.
Also, the powerfull French fleet can be used to patrol the coast between New York and Boston and I think bombard the coastal cities when attacking (not sure how to do that yet).
4) The South and Canada, while important, can be left for last because its more difficult to maintain large armies in the field in these areas. Once you have fullfilled 3, you can send armies to these areas with the comfort of knowing you have somewhere safe to retreat to if you get in trouble. The French fleet can be usefull here too.
5) In general, its better to control coastal cities than inland because if you control most of the coast, you largely negate the huge British naval advantage in the early game.
6) Early in the game, Canada is a death trap for some pretty valuable forces including General Arnold. Its critical to get as many of them south to Ticonderoga or Albany ASAP or they will be wiped out by the British. This is a critical loss and all but dooms Albany to an early British conquest which will allow much more pressure on New York and Philly.
Just like to know what other people's opinions are on these.
Thanks in advance!
UPDATE: Last night I won a complete victory this way with the US by June of 81. I would have won much quicker but it was hard to take Ft. Detroit. Otherwise the Brits were pretty much wiped off the continent or about to be when I hit the victory condition. This was my first win that didn't go down to points.
Also, another use of the French fleet:
7) You can shuttle Spanish troops from the Gulf to South Carolina as well as extra French troops from the islands. This extra army under great leadership can wreak havoc with an otherwise difficult area.
