Siege of Boston Map

Following the battles at Lexington and Concord in April 1775, colonial forces from Massachusetts, Connecticut, New Hampshire, and Rhode Island formed a New England army to surround and contain the British forces occupying Boston. Boston became the center of a developing war between rebelling colonists and British forces. Over the course of 11 months, skirmishes scattered the Boston landscape while both sides built defense lines to keep the other at bay. In early March 1776, the Continental Army, led by George Washington, successfully fortified Dorchester Heights, ultimately forcing the British troops out of town. The final evacuation of the British on March 17 marked the end of the Siege of Boston.
