Where did the Revolutionary War take place?

It took place in what are now the thirteen states of New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, Pennsylvania, Maryland, Delaware, New Jersey, Virginia, North Carolina, South Carolina, Georgia and parts of Canada.

Vermont was part of New York or New Hampshire. (The states squabbled over the territory.)
Maine was not one of the original 13 colonies and might have been part of Canada during the Revolution.
