August 16, 1777, the Revolutionary War’s Battle of Bennington was fought along the shore of the Walloomsac branch of the Hoosac River, and it preserved Continental Army control of a provisions depot 10 miles away in Bennington (site of the Bennington Battle Monument), although the Battle of Bennington was fought in New York State, it has long been celebrated as a Vermont holiday.
Bennington Battle Day is a state holiday unique to Vermont, commemorating the American victory over British forces at the Battle of Bennington during the American Revolutionary War in 1777. The holiday’s date is fixed, occurring on August 16 every year.
In Bennington, there is a battle re-enactment put on by the local history foundation.
The Battle of Bennington actually took place in New York, but is so named because the British were headed for a cache of weapons and munitions stored where the Bennington Battle Monument now stands in present-day Old Bennington, Vermont.
