Siege of Boston

Battle context

The Siege of Boston opened the American Revolutionary War, establishing the terms of the conflict's first sustained military confrontation. American patriot militia, operating under newly installed Continental Army commander George Washington, succeeded in confining British forces to Boston for eleven months, denying them freedom of movement by land. British resupply and reinforcement were restricted to sea access, itself impeded by American vessels, placing the garrison under compounding logistical strain. The siege exposed early resource, supply, and personnel challenges on both sides but ultimately ended with the British evacuation of Boston, withdrawing their troops and equipment north to Nova Scotia. This outcome demonstrated that organized colonial forces could compel a British withdrawal from a major position, lending the patriot cause both strategic and symbolic momentum at the outset of the war.
