West Point

West Point: The Fortress That Held a Revolution Together

Of all the places that shaped the outcome of the American Revolution, few carried as much strategic weight — or as much drama — as the rocky plateau overlooking a sharp bend in the Hudson River known as West Point. George Washington called it "the most important Post in America," and he was not exaggerating. West Point was the linchpin of the Continental Army's strategy to hold the Hudson River corridor, the vital waterway that connected New England to the mid-Atlantic states. Had the British seized and held this position, they could have split the fledgling nation in two, isolating New England's militias and resources from the rest of the war effort. That West Point never fell to the enemy — despite one of the most notorious acts of treason in American history — is a story of engineering brilliance, raw courage, and extraordinary luck.

The strategic importance of the Hudson Highlands was apparent from the war's earliest days. Just weeks after the war ignited at Lexington and Concord, Washington served on a committee tasked by the Continental Congress to assess the river's defenses. Following that committee's recommendation, the Continental Congress approved a resolution on May 25, 1775, to erect batteries on each side of the river's highlands to protect against British naval incursions.

A lack of money, time, and experienced military engineers thwarted Washington's desire to immediately fortify West Point. Instead, work began on Fort Constitution on the opposite bank of the river — on what was then called Martelaer's Rock, later renamed Constitution Island — and in March 1776, Washington ordered the construction of Fort Montgomery and Fort Clinton to defend a giant iron chain, meant to deter British ships, that spanned the Hudson five miles downriver from West Point.

But the first major test came in October 1777, when British forces under General Sir Henry Clinton launched an assault against Forts Clinton and Montgomery, twin fortifications guarding the river about six miles south of West Point. On October 6, Clinton's troops overwhelmed the garrison defenders in a brutal fight that demonstrated both the vulnerability of fixed river defenses and the determination of the British to control the Hudson. The forts fell, the iron chain stretched between them was broken, and British warships sailed upriver, burning Kingston and threatening Albany. The loss was a sobering lesson for the Continental Army. Though the British eventually withdrew — largely because General John Burgoyne's campaign to the north was collapsing toward surrender at Saratoga — the episode made clear that the Americans needed a far stronger defensive position on the Hudson. That position would be West Point.

The site had natural advantages that no other point on the river could match. Vessels passing by West Point had to make a sharp, ninety-degree turn to the west, sail a quarter of a mile, then make another right-angle turn to the north as they continued upriver — bends sharper than at any other point along the Hudson, creating extraordinary hazards for ships attempting to pass.

The distinctive S-curve and the narrowness of the river would force any large ship to tack against the strong current and frequently unfavorable winds, while significant tidal effects only added to the difficulty of navigating the passage.

On January 27, 1778, Brigadier General Samuel Holden Parsons and his brigade crossed the ice on the Hudson River and climbed to the plain on West Point — making it the longest continually occupied post in America. To reinforce the defenses, Washington personally selected Thaddeus Kosciuszko, a Polish engineer, to design the fortifications for West Point in 1778.

Having impressed Washington with his defensive strategy at Saratoga, the French-trained military engineer who had arrived from Poland in 1776 brought a bold and innovative vision to the task. Rather than erecting a single massive masonry structure in the eighteenth-century tradition, Kosciuszko developed an innovative plan linked to an integrated system of smaller forts, each sited on commanding terrain. The lynchpin of his system was a bastion sited on the tip of West Point overlooking the river.

By July 1778, the primary fortification — named Fort Arnold after Benedict Arnold — was basically completed on "The Plain," 145 feet above the Hudson. But the key to Kosciuszko's design was constructing a layered, integrated network of fortifications for mutual defense. For this he turned to the hills surrounding The Plain. Above Fort Arnold were two steep hills, Crown and Rocky; initially they had been deemed unscalable, with no need to fortify them. Kosciuszko surveyed the area and disagreed with that assessment. He convinced General McDougall to change his mind, and work began on Crown Hill, which eventually became known as Fort Putnam.

Built by Colonel Rufus Putnam's 5th Massachusetts Regiment, Fort Putnam was completed in 1778 with the purpose of supporting Fort Clinton, which sat on the edge of the Hudson River about three-quarters of a mile away.

Sitting at an altitude of 500 feet above sea level, it was West Point's largest garrison during the Revolutionary War.

Before the summer was out, the forts manned by the regiments of Colonel Samuel Webb, Colonel Return Jonathan Meigs, and Colonel Samuel Wyllys were also under construction, as were Redoubts North and South on the east side of the Hudson.

When finished, the complex — now referred to as Fortress West Point — consisted of a collection of four forts and seven smaller redoubts.

Alongside the fortifications, the Americans deployed their most audacious piece of defensive engineering: the Great Chain. The contract for the forge specified that the chain would be made of Sterling Iron — stronger than iron from other area mines — mined and forged at Sterling Forge in Warwick, New York. The huge links were carried a few at a time to a forge nearer the Hudson to be assembled.

The chain, known as the Great Chain, was placed in the river on April 30, 1778, measured approximately 1,600 feet, and weighed between 180 and 186 tons.

Spanning the river between the west bank and Constitution Island, the chain was supported by log rafts stretched across the water to impede British movement north of West Point.

An additional engineering curiosity is the probability that there was a way of lowering the chain at the western end to allow friendly ships to pass — garrison orders from August 1780 directed that every vessel approaching be examined and none allowed over the chain without a passport from the governor of the state, hinting at a complexity far beyond a simple obstruction. The Great Chain at West Point was never tested by the Royal Navy.

After the British evacuation of Philadelphia, Washington wanted to keep a close eye on British headquarters in New York City, in case they tried another strike to the north. After moving around New Jersey and New York for a year, Washington established his headquarters at West Point on July 8, 1779, for four months.

His headquarters was the home of Colonel Stephen Moore, an American Patriot, Revolutionary
