The Story
# Knox Proposes the Fort Ticonderoga Artillery Mission
By the autumn of 1775, the American siege of Boston had settled into a frustrating and seemingly unbreakable stalemate. Following the bloody battles of Lexington, Concord, and Bunker Hill earlier that year, General George Washington had assumed command of the Continental Army in Cambridge, Massachusetts, tasked with the enormous challenge of dislodging the British forces garrisoned within the city. Washington's troops, while spirited and numerous enough to maintain a perimeter around Boston, lacked the one critical element that could force the issue: heavy artillery. Without cannon powerful enough to threaten the British positions and the Royal Navy ships anchored in the harbor, Washington could neither bombard the enemy into submission nor fortify the heights overlooking the city in a way that would make the British position untenable. The war effort, still in its infancy, desperately needed a breakthrough.
Enter Henry Knox, a twenty-five-year-old former Boston bookseller whose unlikely path to military prominence was shaped by an insatiable appetite for reading. Knox had spent years in his London Book-Store devouring volumes on military science, engineering, and artillery tactics, acquiring a depth of theoretical knowledge that few officers in the fledgling Continental Army could match. Despite having no formal military training or battlefield command experience, Knox had already impressed Washington with his intelligence, confidence, and deep understanding of ordnance. When Washington confided his frustrations about the army's dire shortage of heavy weaponry, Knox saw an opportunity and stepped forward with a bold proposal that would alter the course of the siege and, indeed, the early trajectory of the Revolution itself.
Knox's plan was as audacious as it was logistically daunting. Months earlier, in May 1775, American forces under Ethan Allen and Benedict Arnold had captured Fort Ticonderoga, a British stronghold on the southern shore of Lake Champlain in upstate New York. The fort contained a substantial cache of British artillery — cannon, mortars, and howitzers — that had been sitting largely unused since the fort's capture. Knox proposed traveling nearly three hundred miles to Ticonderoga, selecting the most serviceable pieces, and hauling them overland back to Cambridge through the harsh New England winter. The route would require crossing frozen lakes, navigating the rugged Berkshire Mountains, and transporting what would amount to roughly sixty tons of iron and brass across terrain that was barely passable even in favorable conditions.
Washington, recognizing both the brilliance and the necessity of the plan, gave Knox his full approval and commissioned him as a colonel of the Continental Regiment of Artillery. Knox departed Cambridge in late November 1775, beginning what would become one of the most celebrated logistical feats of the entire Revolutionary War. Meanwhile, Martha Washington arrived in Cambridge in December to join her husband at his headquarters, providing personal support and a measure of domestic stability during the long, anxious weeks as Washington awaited word of Knox's progress. Her presence at camp became a tradition she would maintain throughout the war, bolstering morale among officers and soldiers alike.
Knox's legendary winter journey, accomplished with ox-drawn sleds, flat-bottomed boats, and sheer determination, succeeded against extraordinary odds. By late January 1776, he and his men had delivered approximately sixty tons of captured artillery to the outskirts of Cambridge. The arrival of these weapons fundamentally transformed the strategic calculus of the siege. Washington used the cannon to fortify Dorchester Heights in early March 1776, placing the British garrison and fleet under direct threat of bombardment. Faced with this newly untenable position, British General William Howe chose to evacuate Boston entirely on March 17, 1776, handing the Americans their first major strategic victory of the war.
The significance of Knox's proposal and its successful execution cannot be overstated. It demonstrated that the Continental Army could achieve results through ingenuity and determination even when it lacked the resources and professional training of its adversary. It elevated Henry Knox to a position of lasting importance — he would serve as Washington's chief artillery officer throughout the war and later become the nation's first Secretary of War. Most importantly, the liberation of Boston provided a vital morale boost to the patriot cause at a moment when the outcome of the Revolution remained deeply uncertain, proving that bold ideas and resolute action could overcome seemingly impossible obstacles.
