At Fort Ticonderoga, Henry Knox begins his historic transport of artillery to Cambridge, Massachusetts.

Fort Ticonderoga, formerly Fort Carillon, is a large 18th-century star fort built by the French at a narrows near the south end of Lake Champlain in northern New York. It was constructed between October 1755 and 1757 by French-Canadian military engineer Michel Chartier de Lotbinière, Marquis de Lotbinière during the French and Indian War, sometimes known overseas as the "North American theater" of the Seven Years' War. The fort was of strategic importance during the 18th-century colonial conflicts between Great Britain and France, and again played an important role during the American Revolutionary War.

Henry Knox was an American military officer, politician, bookseller, and a Founding Father of the United States. Knox, born in Boston, became a senior general of the Continental Army during the Revolutionary War, serving as chief of artillery in all of George Washington's campaigns. Following the war, he oversaw the War Department under the Articles of Confederation from 1785 to 1789. Washington appointed him the nation's first Secretary of War, a position which he held from 1789 to 1794. He is well known today as the namesake of Fort Knox in Kentucky, which is often conflated with the adjacent United States Bullion Depository.

The noble train of artillery, also known as the Knox Expedition, was an expedition led by Continental Army Colonel Henry Knox to transport heavy weaponry that had been captured at Fort Ticonderoga to the Continental Army camps outside Boston during the winter of 1775–76. Knox went to Ticonderoga in November 1775 and moved 60 tons of cannon and other armaments over the course of three winter months by boat, horse, ox-drawn sledges, and manpower along poor-quality roads, across two semi-frozen rivers, and through the forests and swamps of the lightly inhabited Berkshires to the Boston area, covering approximately 300 miles (500 km). Historian Victor Brooks has called Knox's exploit "one of the most stupendous feats of logistics" of the American Revolutionary War. The route he took is now known as the Henry Knox Trail.
