The Battle of Hubbardton is an engagement in the Saratoga campaign of the American Revolutionary War fought in the village of Hubbardton, Vermont.

Vermont is at this time a disputed territory sometimes called the New Hampshire Grants, claimed by New York, New Hampshire, and the newly organized and not yet recognized but de facto independent government of Vermont.

On the morning of July 7, 1777, British forces, under General Simon Fraser, catch up with the American rear guard of the forces retreating after the withdrawal from Fort Ticonderoga.

It is the only battle in Vermont during the revolution. (The Battle of Bennington is fought in what is now Walloomsac, New York.)

The American retreat from Fort Ticonderoga begins late on July 5 after British cannons are seen on top of high ground, Mount Defiance (a.k.a. Rattlesnake Mountain and Sugar Loaf Hill) that commands the fort.

The bulk of General Arthur St. Clair's army retreats through Hubbardton to Castleton, while the rear guard, commanded by Seth Warner, stops at Hubbardton to rest and pick up stragglers.

General Fraser, alerted to the American withdrawal early on July 6, immediately sets out in pursuit, leaving a message for General John Burgoyne to send reinforcements as quickly as possible.

That night Fraser camps a few miles short of Hubbardton, and the German General Friedrich Adolf Riedesel, leading reinforcements, camps a few miles further back.

Rising early in the morning, Fraser reaches Hubbardton, where he surprised some elements of the American rear, while other elements managed to form defensive lines.

In spirited battle, the Americans are driven back, but have almost succeeded in turning Fraser's left flank when Riedesel and his German reinforcements arrive, eventually scattering the American forces.

The battle takes a large enough toll on the British forces that they do not further pursue the main American army.

The many American prisoners are sent to Ticonderoga while most of the British troops make their way to Skenesboro to rejoin Burgoyne's army.

Most of the scattered American remnants make their way to rejoin St. Clair's army on its way toward the Hudson River.
