Knox Transports Crown Point and Ticonderoga Cannon to Boston

# Knox Transports Crown Point and Ticonderoga Cannon to Boston

By the autumn of 1775, the American Revolution had reached an uncomfortable stalemate outside Boston. Following the battles of Lexington and Concord the previous April, thousands of colonial militia had converged on the city, trapping General William Howe and his British garrison within its narrow peninsula. General George Washington, who had assumed command of the Continental Army in July, possessed enough men to maintain a siege but lacked the heavy artillery necessary to bring it to a decisive conclusion. His forces had muskets and a scattering of light field pieces, but nothing powerful enough to threaten the British warships anchored in the harbor or to bombard fortified positions from a commanding distance. Washington knew that without cannon, the siege could drag on indefinitely, sapping morale and giving the British time to receive reinforcements. The solution to this seemingly impossible problem lay nearly three hundred miles to the northwest, at the recently captured forts of Ticonderoga and Crown Point on the shores of Lake Champlain in New York.

Earlier that year, in May 1775, a combined force led by Ethan Allen and his Green Mountain Boys, along with Benedict Arnold, had seized Fort Ticonderoga in a daring dawn raid that caught the small British garrison completely by surprise. Crown Point, a nearby fortification, fell shortly afterward. Both forts contained substantial stores of artillery that the British had accumulated over decades of frontier warfare and conflict with the French. These weapons now belonged to the American cause, but they sat idle in the remote wilderness of upstate New York, far from where they were desperately needed.

In November 1775, Washington turned to Henry Knox, a twenty-five-year-old Boston bookseller turned artillery officer whose deep study of military engineering and ordnance had earned him the general's trust despite his lack of formal military training. Washington dispatched Knox northward with orders to retrieve the captured guns and deliver them to the siege lines around Boston. What followed was one of the most remarkable logistical feats of the entire Revolutionary War. Knox arrived at Ticonderoga and Crown Point and organized the collection of approximately sixty tons of cannon, mortars, and howitzers — somewhere around sixty individual pieces of various calibers. He then arranged for this enormous weight of iron and bronze to be loaded onto flat-bottomed boats and ferried down Lake George. When the lake's waters froze, Knox adapted his plans, transferring the weapons to massive ox-drawn sleds that could traverse the ice. From there, the artillery train had to be hauled overland across the rugged Berkshire Mountains of western Massachusetts, through snow, ice, and terrain that tested the endurance of men and animals alike. Rivers had to be crossed, and on more than one occasion cannons broke through thin ice, requiring exhausting efforts to recover them. Knox drove the operation forward with relentless energy and resourcefulness, coordinating teams of oxen, horses, and local volunteers across miles of frozen wilderness.

By late January 1776, Knox and his extraordinary caravan arrived in the Continental Army's camp outside Boston. Washington now had the firepower he needed. On the night of March 4–5, 1776, Continental troops moved swiftly to fortify Dorchester Heights, the elevated ground overlooking Boston Harbor, and emplaced Knox's heavy guns in positions that directly threatened the British fleet and the city below. When morning revealed the American batteries looming overhead, General Howe recognized that his position had become untenable. The cannon could rain destruction on his ships and troops, and a direct assault on the fortified heights would risk a catastrophe reminiscent of the British losses at Bunker Hill. Faced with this grim calculus, Howe chose evacuation. On March 17, 1776, the British fleet sailed out of Boston Harbor, carrying the garrison and roughly a thousand Loyalist civilians to Halifax, Nova Scotia.

The significance of Knox's noble train of artillery, as it came to be known, cannot be overstated. It transformed a static and frustrating siege into a decisive American victory without a major battle, delivering the first great strategic success of the Revolution and providing an enormous boost to patriot morale throughout the colonies. It also demonstrated that the Continental Army could execute complex operations requiring planning, coordination, and sheer determination — qualities that would prove essential in the long years of war ahead.
