Looking at just the sheer number of battles, the Revolution was fought predominantly in the Carolinas, with New Jersey being the most hotly contested northern state. That doesn’t delve into strategic importance or number of casualties, but I suspect the picture wouldn’t change all that much due to those considerations.
I’ve often thought that our nation’s founding became politicized due to the Civil War, with first settlement moving to Plymouth from Jamestown and the Revolution becoming more of a New England affair as far as the history books indicated, in the aftermath of that conflict. The victors get to write the history books.
In light of that historical truism, it seems as if we’ve lost another war that most didn’t even understand was being fought, if modern history books are any indication. It was apparently a very racial conflict, too.
These are some interesting observations. I grew up in New Jersey, and visited and camped at places like Crown Point and Ticonderoga. About 10 years ago I began work on a historical novel about the notorious Harpe brothers. Thus I learned about and ended up visiting places like Cowpens and Kings Mountain.
Up north we learned very little about the southern battles of the Revolution except the final one at Yorktown. This success would not have been possible without the sapping of British strength in the south from folks like Francis Marion, or the Overmountain Boys. Of course we must give some credit to French assistance especially at the end with their naval blockade. It helped too that India was more important economically to Britain than America.
