All of the huts at the New Windsor Cantonment are reconstructions, but this one was built from original materials, which were removed and used for a building on a nearby farm. Later they were donated by the farm owners to make this hut. There were once over 600 such huts, with upwards of 32 soldiers in each. Note the reference to Nathaniel Sackett in the extract below. He’s a fascinating character in his own right: Washington’s spymaster, and later sutler (a civilian merchant who sells provisions to an army in the field, in camp, or in quarters. Sutlers sold wares from the back of a wagon or a temporary tent, traveling with an army or to remote military outposts).
According to A Revolutionary War Road Trip on US Route 9W, May 26, 2004 by Raymond C. Houghton:
After the Continental Army troops left the [New Windsor] cantonment in June 1783, the Quartermaster Department began selling buildings and equipment for which it had no further use. According to local tradition, Nathaniel Sackett, an area merchant purchased one or more of the huts. He took them to his property in nearby Mountainville, near Cornwall, where they became the wing of a private dwelling. “Rediscovered” in 1933, the structure was dismantled and reassembled here at Temple Hill.
