A Plan of the Town and Harbour of Boston, by J. De Costa, 1775 165
Done from an actual survey and dedicated to Richard Whitworth, M.P., this map was completed almost a month and a half after the Battle of Bunker Hill; yet it takes no notice of that event. Besides the islands in the harbor, which are placed with more than usual accuracy, the mapmaker shows the position of troops under the command of Generals Thomas and Putnam. Nothing is known of De Costa (Emerson D. Fite and Archibald Freeman, A Book of Old Maps, Cambridge, 1926, p. 255). The plan has been cropped here.
