BOSTON (AP) — More than a decade before he became the country's first president, George Washington was leading a critical campaign in the early days of the American Revolution. The Siege of Boston was his first campaign as commander-in-chief of the Continental Army and, in many ways, set the stage for his military and political successes — celebrated on Presidents Day.

Following the Battles of Lexington and Concord, militias had pinned down the British in Boston in April 1775. The Continental Congress, recognizing the need for a more organized military effort, selected Washington to lead the newly formed army.

The Siege of Boston and its significance

On this day 250 years ago, Washington would have been nearing the end of an almost yearlong siege that bottled up as many as 11,000 British troops and hundreds more loyalists. The British were occupying Boston at the time, and the goal of the siege was to force them out.

A critical decision made by Washington was sending Henry Knox, a young bookseller, to Fort Ticonderoga in New York to retrieve dozens of cannons. The cannons, transported hundreds of miles in the dead of winter, were eventually used to fire on British positions. That contributed to the decision by the British, facing dwindling supplies, to abandon the city by boat on March 17, 1776.

Historians argue that the British abandoning their positions, celebrated in Boston as Evacuation Day, rid the city of loyalists at a critical time, denied the British access to an important port and gave patriots a huge morale boost.

“The success of the Siege of Boston gave new life and momentum to the Revolution,” Chris Beagan, the site manager at Longfellow House in Cambridge, a National Historic Site that served as Washington's headquarters during the American Revolution. “Had it failed, royal control of New England would have continued, and the Continental Army likely would have dissolved."

How the siege shaped Washington

The siege was also a critical test for Washington. A surveyor and farmer, Washington had been out of the military for nearly 20 years after commanding troops for the British during the French and Indian War. His successful campaign ensured Washington remained the commander-in-chief for the remainder of the revolution.

Doug Bradburn, president of George Washington’s Mount Vernon, said Washington took the first steps to creating a geographically diverse army that included militiamen from Massachusetts to Virginia and, by the end of the war, a fighting force with significant Black and Native American representation. It was the most integrated military until President Harry S. Truman’s desegregated the armed forces in 1948, he said.
