One of the earliest obtainable maps relating to the Revolution, this map is based on an original drawn in June 1775, probably only days before the Battle of Bunker Hill.
The depiction of Boston proper is striking-at the time, the city was essentially an island linked to the mainland via a narrow causeway. No street detail is given, but the Common, Mill Pond and Long and Hancock’s Wharves are identified.
Though small in scale, the plan conveys well the military situation in the early stages of the American siege of British-occupied Boston. Among the military details shown are the Provincial (i.e., Washington’s) headquarters in Cambridge; fortifications at either end of Boston Neck; the camps and lines of Generals Putnam and Ward; Copp’s, North, and South Batteries in Boston proper, and ships and batteries surrounding Charlestown.
The siege lasted until 1776, when during the night of March 4th the American army fortified Dorchester Heights to the south, giving them command of both the town and its harbor approaches. A planned British assault on the Heights was called off due to bad weather, and the city was evacuated on March 17.
The plan was published in the August 1775 issue of J. Almon’s The Remembrancer, one of the many monthly journals combining literary reprints, original contributions and news that proliferated in mid-18th century England.
