Congressman Billybob
Respectfully, Congressman, I think it more accurate to say that the American Revolution was begun in New England, and won in America.
Saratoga is rightly called the turning point for a few reasons: 1) if Burgoyne had won, the colonies would have been cut in half and 2) the French would not have thrown in with us. Thus, victory would likely never have occurred. Saratoga was fought mainly by northerners (with help from Morgan's riflemen to be sure). I could give other examples, but you get the idea.
The RevWar was won because the North and the South threw down together against a common enemy. This was nicely demonstrated by the State of Georgia granting that pure Yankee, Nathaneal Greene,a nice bit of land after the war.
One thing that was not mentioned in this article was that after Greene's death, another Yankee visited Kitty Greene and asked her if he could tinker in her barn with something he was working on. His name was Eli Whitney.
