September 1, 1774–March 17, 1776
The Boston campaign was the opening
campaign of the American Revolutionary War. The campaign
was primarily concerned with the mobilization of Patriot
militia units, and their transformation into a unified
Continental Army. The campaign's military conflicts
started with the Battles of Lexington and Concord on April 19,
1775, in which militias turned out according to plan to
interdict and harass the British attempt to seize military
stores and leaders in Concord, Massachusetts. The entire
British expedition suffered significant casualties during a
running battle back to Charlestown against an ever-growing
number of militia.
The accumulated militia surrounded
the city of Boston, beginning the Siege of Boston. The main
action during the siege, the Battle of Bunker Hill on June 17,
1775, was one of the bloodiest encounters of the entire war.
There were also numerous skirmishes near Boston and the
coastal areas of Boston, resulting in either loss of life,
military supplies, or both.
In July 1775, George
Washington took command of the assembled militia and
transformed them into a more coherent army. On March 4, 1776,
the Patriot army fortified Dorchester Heights with cannon
capable of reaching Boston and British ships in the harbor.
The siege (and the campaign) ended on March 17, 1776, with the
withdrawal of British forces from Boston.
