Have there been any battles, from any war, fought in New Hampshire?

Answer 1

As far as I know there were no battles fought in New Hampshire, either during the Revolutionary War or the Civil War. There may be some from the French-Indian War, I don't know.
A pre-Revolution event occurring in New Hampshire was the removal in 1774, by a small party of patriots at New Castle, of the powder and guns at Fort William and Mary. Other Revolutionary events included New Hampshire’s participation in the Battle of Bunker Hill at which nearly all the troops doing the actual fighting were said to have been from this State; the signing of the Declaration of Independence by New Hampshire’s Josiah Bartlett, Matthew Thornton, and William Whipple; General John Stark’s victory at the Battle of Bennington; and the success of Captain John Paul Jones at sea.

Answer 2

i'd be surprised if there wasn't at least one from either the Revolutionary or the Civil War.
