Fort Montgomery (Hudson River) (Highlands, New York)

Highlands · New York · American Revolution

Quick BriefFort Montgomery was built on the west bank of the Hudson River in Highlands, New York by the Continental Army during the American Revolution. Erected in 1776, it was one of the first major investments by the Americans in strategic construction projects. On October 6, 1777, a combined force of roughly 2,100 Loyalists, Hessians, and British regulars led by Lieutenant General Sir Henry Clinton attacked the fort from the landward side with support from cannon fire from British ships on the Hudson River.

History & Significance

The strategic importance of controlling navigation along the Hudson River was obvious to both Americans and the British from the outbreak of open hostilities, as the river was the major means for transportation of supplies and troops throughout a large portion of the northeast. In July 1776, the New York convention appointed a committee, including John Jay, Robert Livingston, George Clinton and Robert Yates, to devise and execute measures for obstructing the channel of the Hudson River.

Construction began in March 1776 at the confluence of Popolopen Creek with the Hudson River near Bear Mountain in Orange County, New York. The fortifications included a river battery of six 32-pound cannons, a cable chain supported by a boom across the Hudson River, and landward redoubts connected by ramparts, all situated on a cliff promontory rising 100 feet above the river.

General George Clinton, the newly appointed Patriot governor of the State, commanded the fort, which held a combined garrison of roughly 700 Colonial soldiers with its companion fortification, Fort Clinton. Although the British captured both forts on October 6, 1777, the campaign caused delays in reinforcing General John Burgoyne at Saratoga, enabling Americans to gain the upper hand at the Battle of Bemis Heights and force Burgoyne's surrender ten days later. The site was declared a National Historic Landmark in 1972.
