Cortlandt Manor in Westchester County, New York — The American Northeast (Mid-Atlantic)
Chaining the Hudson
Lieutenant Thomas Machin, one of the Continental Army's most able engineers, directed the work on the forts and the chain. During two separate attempts, the chain quickly broke under the strain of the ebb tide. Convinced that the chain could still work, Machin had the damage repaired and successfully stretched it across the river in March 1777.
British ships never tested the chain. Rather, the British captured the forts on October 6, 1777 and cut the chain the following day. Today, Fort Montgomery State Historic Site is open to the public and interprets the story of the forts and battle.

A plan of the Forts Montgomery and Clinton, by Major Holland, Surveyor General of the Northern District of North America, ca. 1777. The map shows the forts, the chain, and the small fleet of American ships that defended the Hudson when the British attacked. In July 1777, cables from the two American frigates were run across the river in front of the chain to help protect it. Library of Congress, Geography and map Division.

7. Detail from the Marker
A portion of the Fort Montgomery chain was originally constructed to block the Richelieu River. It was carried far to the north only to return south when the American invasion of Canada failed in early 1776. The Americans considered using it at Fort Ticonderoga to block Lake Champlaign, but chose instead to return it to the Hudson River to become part of the Fort Montgomery chain.

The Fort Montgomery chain was made from 1.5- and 2-inch iron bars from furnaces at Ancram, New York, and Ringwood and Mount Hope in New Jersey. The 1,650-foot-long chain consisted of about 850 links floated on giant pine logs.
