The Battle of Bennington is a battle of the American Revolutionary War, part of the Saratoga campaign, that takes place on August 16, 1777, in Walloomsac, New York, about ten miles (sixteen kilometers) from its namesake Bennington, Vermont.

A rebel force of two thousand men, primarily composed of New Hampshire and Massachusetts militiamen, led by General John Stark, and reinforced by Vermont militiamen led by Colonel Seth Warner and members of the Green Mountain Boys, decisively defeats a detachment of General John Burgoyne's army led by Lieutenant Colonel Friedrich Baum, and supported by additional men under Lieutenant Colonel Heinrich von Breymann.

Baum's detachment is a mixed force of seven hundred composed primarily of Hessians but also including small amounts of dismounted Brunswick dragoons, Canadians, Loyalists, and Indians.

He is sent by Burgoyne to raid Bennington in the disputed New Hampshire Grants area for horses, draft animals, provisions, and other supplies.

Believing the town to be only lightly defended, Burgoyne and Baum are unaware that Stark and fifteen hundred militiamen are stationed here.

After a rain-caused standoff, Stark's men envelop Baum's position, taking many prisoners, and killing Baum.

Reinforcements for both sides arrive as Stark and his men are mopping up, and the battle restarts, with Warner and Stark driving away Breymann's reinforcements with heavy casualties.

The battle is a major strategic success for the American cause; it reduces Burgoyne's army in size by almost one thousand men, leads his Indian support to largely abandon him, and deprives him of much-needed supplies, such as mounts for his cavalry regiments, draft animals and provisions; all factors that contribute to Burgoyne's eventual defeat at Saratoga.

The victory galvanizes colonial support for the independence movement, and plays a key role in bringing France into the war on the rebel side.

The battle's anniversary is celebrated in the state of Vermont as Bennington Battle Day.
