LOADING MAP TELEMETRY…
Overview
The siege of Boston was the opening phase of the American Revolutionary War. In the siege, American patriot militia led by newly-installed Continental Army commander George Washington prevented the British Army, which was garrisoned in Boston, from moving by land. Both sides faced resource, supply, and personnel challenges during the siege. British resupply and reinforcement were limited to sea access, which was impeded by American vessels. The British ultimately abandoned Boston after eleven months, moving their troops and equipment north to Nova Scotia.

Significance
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.
