This anticipated batteries at both existing and planned defensive fortifications. In late 1776 Henry Wisner, a resident of

in 1778, known as the Great Chain. A fourth, a cheval de frise started in 1776 between Plum Point on the east bank and Pollepel Island north of West Point, was begun but abandoned. The first two were promptly captured by the British, while the Great Chain, the largest and most important of the projects, was reset each spring until the end of the war. Attention was concentrated on the West Point area because the river narrowed and curved so sharply there that ships slowed in navigating the passage by shifting winds, tides, and current made optimal targets.


Fort Lee to Fort Washington cheval de frise (1776)

In 1776 the Continental Army constructed an array of logs sunk underwater between Fort Washington on the island of Manhattan and Fort Lee across the river in New Jersey. Built to a design of Scottish engineer turned Colonial sympathizer Robert Erskine, the logs were intended to pierce and sink any British ships that passed over them. An opening was left for the passage of American ships. After the British learned of the opening from a local resident, they successfully passed through the barrier several times. The British successfully captured both forts in the

on November 20, putting the defensive barrier in their hands. This change had little impact, as the nascent American Navy lacked ships of the size and power of the British, leaving it to resort to small and more maneuverable vessels regardless.

were stretched across the river from Fort Montgomery on the west bank, at the lower entrance to the Highlands just north of the modern-day Bear Mountain Bridge, to Anthony's Nose on the east bank. Captain Thomas Machin headed the chain effort. In November 1776, a faulty link broke under stress induced by the river current, highlighting some of the difficulties of trying to chain the Hudson. It was repaired and reset. After the British captured forts Montgomery and Clinton, a second fortress built opposite it at the mouth of Popolopen's Kill (today's Popolopen Creek) on its south bank, on 6 October 6 1777, they dismantled the chain. Free to do so, they raided upriver as far as Kingston, then the capitol of New York State, putting the torch to it and burning all but several of its hundreds of buildings to the ground. Governor George Clinton, a member of the committee assigned by the New York Convention to devise a means of defending the Hudson, was heartened as the British had never attempted to run ships through the chain. He concluded that the basic idea of obstructing the river seemed sound. After Captain Machin recovered from wounds from battle with the British, he began work on the stronger Great Chain at West Point, which was constructed and installed in 1778.


Pollepel Island cheval de frise (1776–1777)

Another cheval de frise was undertaken across the Hudson between Plum Point on the east bank and Pollepel Island north of West Point. The defenses were never fully completed, and its importance was overshadowed by completion of the Great Chain at West Point the following year.


Great Chain (1778–1782)

In the spring of 1778, a heavy chain supported by huge log rafts was stretched across the Hudson from West Point to Constitution Island to impede the movement of British ships north of West Point. A second log boom (resembling a ladder in construction) spanned the river about downstream to absorb the impact of any ship attempting to breach the barrier. The Hudson River's changing tides, strong current, and frequently unfavorable winds created adverse sailing conditions at West Point. Compounding this, the river's narrow width and sharp "S-Curve" there forced any large ship to

in order to navigate it. Cannon were placed in forts and artillery batteries on both sides of the river to attack ships when they were slowed to a halt by the Patriot barrier placed there. The chain was constructed over six weeks at the Sterling Iron Works in

, Orange County, of chain links from Long Pond Iron Works in Ringwood, New Jersey. When completed, the chain contained iron links in length, weighing . The links were carted to New Windsor, where they were put together and floated down the river to West Point on logs late in April. Including swivels, clevises, and anchors, the chain weighed 65 tons. For buoyancy, logs were cut into lengths, waterproofed, and joined by fours into rafts fastened to one another with timbers. Short sections of chain (10 links, a swivel, and a clevis) were attached across each raft then joined to create a continuous boom of chains and rafts once afloat. Captain Thomas Machin, the artillery officer and engineer who had installed the chain at Fort Montgomery, directed installation across the river on 30 April 1778. Both ends were anchored to log cribs filled with rocks, the southern at a small cove on the west bank and the northern at Constitution Island. The West Point side was protected by the Chain Battery and the Constitution Island side by the Marine Battery. A system of pulleys, rollers, ropes, and mid-stream anchors were used to adjust the chain's tension to overcome the effects of river current and changing tide. Until 1783, the chain was removed each winter and reinstalled each spring to avoid destruction by ice. The British never attempted to run the chain, in spite of
