Seth Warner Seizes Crown Point

# Seth Warner Seizes Crown Point

In the spring of 1775, the American colonies teetered on the edge of full-scale war with Great Britain. The battles of Lexington and Concord on April 19 had shattered any remaining illusion of peaceful reconciliation, and across New England, militiamen and irregular fighters began looking for ways to strike at British military power. Among the most strategically important targets in the northern colonies were the old fortifications along the Lake Champlain corridor in New York, a waterway that had served as a vital military highway between Canada and the American interior since the French and Indian War. It was in this context that one of the early, decisive moves of the American Revolution unfolded — not with a dramatic battle, but with a quiet and almost bloodless seizure that would have enormous consequences for the rebel cause.

On May 10, 1775, Ethan Allen, the bold and outspoken commander of the Green Mountain Boys, led a daring predawn raid on Fort Ticonderoga, catching the small British garrison completely off guard and capturing the fortress without a single casualty on either side. The Green Mountain Boys were a militia originally formed in the disputed territory known as the New Hampshire Grants, the land that would eventually become Vermont, and they were no strangers to defiance of authority. Allen's capture of Ticonderoga was a stunning early triumph for the patriot cause, but the work along Lake Champlain was not yet finished. Just twelve miles to the north sat another fortification of considerable importance: Crown Point.

Two days after the fall of Ticonderoga, on May 12, 1775, Colonel Seth Warner led a detachment of Green Mountain Boys northward to Crown Point to complete what Allen had begun. Warner, a seasoned and respected officer within the Green Mountain Boys, was known for his steadiness and tactical competence — qualities that complemented Allen's more flamboyant style of leadership. When Warner and his men arrived at Crown Point, they found a British garrison of only nine soldiers, a skeleton force that had no realistic hope of mounting a defense against the approaching rebels. The British troops offered no resistance, and the fort passed into American hands without a shot being fired.

Though the seizure of Crown Point lacked the dramatic flair of Allen's surprise attack on Ticonderoga, its strategic significance was immense. Together, the two captures gave the Americans undisputed control of the Lake Champlain corridor, a critical north-south route that could serve as either an invasion path from Canada or a defensive barrier against British forces moving south. Equally important was the military hardware the Americans found within the walls of both forts. Combined, the captured fortifications yielded over one hundred pieces of artillery — cannons, mortars, and howitzers — at a time when the Continental forces were desperately short of heavy weapons.

The true impact of these captured guns would not be felt for several months, but when it came, it proved decisive. In the winter of 1775–1776, General Henry Knox of the Continental Army undertook an extraordinary logistical feat, organizing the transport of dozens of heavy cannons from Ticonderoga and Crown Point across nearly three hundred miles of frozen wilderness to the outskirts of Boston. When these guns were placed on Dorchester Heights overlooking the city and its harbor, the British position became untenable. In March 1776, the British evacuated Boston entirely, a pivotal early victory for the American cause that owed its success, in no small part, to the artillery secured months earlier by men like Seth Warner and Ethan Allen.

The seizure of Crown Point reminds us that not every critical moment in a revolution arrives with the thunder of musket fire. Sometimes, the course of history turns on quiet acts of initiative carried out by determined individuals who understand the broader stakes of their actions. Seth Warner's march to Crown Point was one such moment — a small event with outsized consequences that helped shape the early trajectory of American independence.
