In October, 1775, an "Engineer at Boston", Lieut. Richard Williams, made and sent over to England a plan showing the "redoubt taken from the rebels by General Howe", the British camp on the higher summit of Bunker Hill, together with the American lines at Cambridge and Roxbury. In London it was compared with "several other curious drawings", from which additions were made, when it was published by Andrew Dury, March 12, 1776, as engraved by Jno. Lodge for the late Mr. Jefferys, and called Plan of Boston and its environs, showing the true situation of his Majesty's Army, and also those of the rebels.[620] In the same month (Oct., 1775) a Plan of Boston, with Charlestown marked as in ruins, appeared in the Gentleman's Magazine (p. 464). Another Map of Boston and Charlestown, by an English officer present at Bunker Hill, was published in London, Nov. 25, 1775. The last map made during the British occupation of Boston was An accurate map of the Country round Boston in New England, published by A. Hamilton, Jr., near St. John's Gate, Jan. 16, 1776, appearing in the Town and Country Magazine. It measures 11-1/2 × 12-1/2 inches, and extends from Plymouth to Ipswich, and inland to Groton and Providence.

The evacuation of Boston in March, 1776, removed the centre of interest elsewhere, but there was for some time an apprehension of the return of the British for a naval attack; and while the Americans were fortifying the harbor, the English were publishing in London several maps of its configuration. The earliest was a Chart of Massachusetts Bay and Boston Harbour, published April 29, 1776. With the date changed to Dec. 1, 1781, it was subsequently included by Des Barres in the Atlantic Neptune, and in the Charts of the Coast and Harbors of New England, 1781.[621] Another Chart of Boston Bay, whose limits include Salem, Watertown, and Scituate, following Holland's surveys, was published Nov. 13, 1776, and later appeared, dated Dec. 1, 1781, in the Atlantic Neptune, and in the Coast and Harbors of New England. A chart of the harbor, with soundings, was also included in the North American Pilot for New England (London, 1776), showing a solitary tree on the peninsula marked "Ruins of Charlestown." There was a second edition of the Pilot in 1800. A small plan of the harbor is also in the margin of Carrington Bowles's Map of the seat of war in New England (London, 1776).

The first eclectic map was that published by Gordon in his Amer. Revolution (London, 1788), which he based on Pelham's map for the country, and Page's for the harbor.[622]

The French maps published in Paris were almost always based on English sources. Such were the Carte de la baye de Baston (no. 30), and Plan de la ville de Baston (no. 31), in Le Petit Atlas maritime, vol. i., Amérique Septentrionale, par le S. Bellin, 1764. There are several other French maps without date, but probably a little antedating the outbreak of hostilities. Such are a Plan de la ville et du port de Boston, published by Lattré in Paris;[623] and a small map, Plan de la ville de Boston et ses environs, engraved by B. D. Bakker. An engraved map, without date, is in the British Museum, called Carte des environs de Boston, capitale de la Nlle Angleterre en Amérique.[624] It carries the coast from below Plymouth to above the Merrimac. There is in the Poore collection of maps in the Mass. State Archives a Carte de la baye de Baston (marked Tome i. no. 30).

The only dated map of this period is a Carte du porte et havre de Boston, par le Chevalier de Beaurain (Paris, 1776). The corner vignette shows a soldier bearing a banner with a pine-tree. Frothingham, who reëngraved this picture, could find no earlier representation of the pine-tree flag.

The English (1774) map of the "most inhabited part of New England" was reproduced "after the original by M. Le Rouge, 1777", under the title of La Nouvelle Angleterre en 4 feuilles; and it was again used in the Atlas Ameriquain Septentrional, à Paris, chez Le Rouge (1778), repeating the map of Boston, with names in English and descriptions in French. Another reproduction from the English appeared in the Carte particulière du Havre de Boston, reduite de la carte anglaise de Des Barres par ordre de M. de Sartine (1780). It belongs to the Neptune Americo-Septentrional, publié par ordre du Roi.

There is among the Rochambeau maps (no. 14), in the library of Congress, a Plan d'une partie de la rade de Boston, done in color, about eight inches wide by sixteen high, showing the forts and giving an elaborate key.

There is a curious map of Boston and its harbor, with names in Latin, but apparently of German make, Ichnographia urbis Boston and Ichnographia portus Bostoniensis, which make part of a larger map, perhaps the Nova Anglia of Homann of Nuremberg. The Geschichte der Kriege in und ausser Europa, published also at Nuremberg in 1776 (erste theil) has a map of Boston. Of the same date (1776), and belonging to the Geographische Belustigungen für Erläuterung der neuesten Weltgeschichte (Zweytes Stück), published at Leipsic, is a Carte von dem Hafen und der Stadt Boston, following the French map of Beaurain even to reproducing the group with the pine-tree banner. It embraces a circuit about Boston of which the outer limits are Chelsea, Cambridge, Dorchester, Long Island, Deer Island, and Pulling Point.
