Knox's Headquarters State Historic Site
From October 1782 until the spring of 1783, as 7,000 soldiers and 500 "camp followers" were establishing winter quarters at the New Windsor Cantonment, and General Washington was lodged at Jonathan Hasbrouck's house in Newburgh, New York, Major General Horatio Gates occupied the 1754 home from which he commanded the cantonment. Here the army awaited the end of the Revolutionary War that became effective when Washington issued the cease fire orders on April 19, 1783.
For most of the 18th and into the 19th century, the Ellison family had important commercial dealings in milling and trade. From their mill, flour was shipped down the Hudson River to New York City and the West Indies. At present, remains of the mill, with traces of the underground racecourse, and the Jane Colden Native Plant Sanctuary may be visited. Visitors can see how the Ellisons and other families of the mid-Hudson Valley lived 200 years ago. Special events are offered seasonally in and around the historic home.
