Henry Knox Trail Marker at Ghent, NY (NY-27)

The Henry Knox Trail, also known as the Knox Cannon Trail, is a network of roads and paths that traces the route of Colonel Henry Knox's "noble train of artillery" from Crown Point, New York, to the Continental Army camp outside Boston, Massachusetts, in the American Revolutionary War.

George Washington commanded Henry Knox in 1775 to transport 59 cannons (weighing over 60 tons) from captured forts on Lake Champlain, 30 from Fort Ticonderoga, and 29 from Crown Point to the army camp outside Boston to aid the war effort against British forces. They included forty-three heavy brass and iron cannons, six coehorns, eight mortars, and two howitzers.

It was originally located near West Ghent Reformed Church on Old Kings Highway just east of State Route 9H. It is now at the intersection of Union Turnpike (New York State Route 66) and Snyder Road, on the right when traveling south on Union Turnpike. 

In the early 1970s, research supported a different route, running southeasterly from Kinderhook across Columbia County to the junction of State Routes 22 and 71 in the county's southeastern corner, then down Route 71 into Massachusetts. In about 1975, the several monuments between Kinderhook and the State Line were relocated to reflect this new direction.
