The
Siege of Boston (April 19, 1775 – March 17, 1776) was the opening phase of the
American Revolutionary War.
New England militiamen prevented the movement by land of the
British Army garrisoned in what was then the
peninsular city of
Boston,
Massachusetts. Both sides had to deal with resource supply and personnel issues over the course of the siege. British resupply and reinforcement activities were limited to sea access. After eleven months of the siege, the British abandoned Boston by sailing to
Nova Scotia.
