This Westfield marker commemorates the passage of Henry Knox’s “noble train of artillery” during the winter of 1775–1776. After the opening battles of the Revolution, American forces surrounded Boston but lacked enough heavy cannon to drive the British army from the town. Knox, a twenty-five-year-old Boston bookseller with a keen interest in military science, proposed transporting the artillery captured at Fort Ticonderoga and Crown Point across hundreds of miles of winter roads to George Washington’s army at Cambridge. Washington approved the plan in November 1775.

Knox reached Fort Ticonderoga in early December and selected fifty-nine pieces: cannon, mortars, howitzers, and coehorns weighing many tons in all. His men moved them by boat down Lake George and then loaded them onto heavy sledges. Teams of oxen and horses hauled the weapons south along the Hudson Valley, east through the Berkshire Mountains, and across western Massachusetts. Thin ice, deep snow, steep grades, broken equipment, and shortages of animals repeatedly threatened the expedition. At several points guns broke through ice or sledges overturned, forcing the crews to recover and reload their cargo.

Westfield lay on the final Massachusetts portion of the route. The artillery train approached through the difficult hill country to the west before continuing toward Springfield, where Knox could use established roads leading to Worcester and Cambridge. The marker does not identify an encampment or surviving building; it records that the column passed through this place. Its location on Main Street reflects the importance of the east-west travel corridor that connected settlements in the Connecticut River valley with Boston.

Knox delivered the artillery to the American lines by late January 1776. Washington concealed his plans while the guns were mounted and ammunition gathered. On the night of March 4–5, Continental troops fortified Dorchester Heights, overlooking Boston and its harbor, and placed heavy cannon in the new works. British commander William Howe recognized that the position endangered both his army and fleet. After a planned assault was disrupted and evacuation preparations completed, British forces departed Boston on March 17.

The cannon train’s passage through Westfield was therefore one link in an operation that produced the first major strategic American success of the war. It demonstrated the Continental Army’s ability to solve immense logistical problems despite poor roads, winter weather, and limited resources. The bronze trail marker, erected by Massachusetts in 1927 during the Revolution’s sesquicentennial, is one of a series tracing Knox’s route. It commemorates both Knox’s initiative and the labor of the soldiers, teamsters, craftsmen, animals, and local residents who moved the weapons that made the liberation of Boston possible.
