Schwartz & Ehrenberg, The Mapping of America, plate 114

A fine example of George Louis le Rouge's edition of one of the most detailed and important maps of the New York region issued during the Revolutionary War period. John Montresor was an English army officer, engineer, and prolific cartographer, whose long career extended from the French and Indian War to the American Revolution. In 1775 he was appointed Chief Engineer for the British Army in North America and published the first edition of this map, largely compiled from surveys he executed during the 1760s. This French edition closely follows the English, with minor additions, and depicts substantial portions of New York, Vermont, Massachusetts, Connecticut, New Jersey and Pennsylvania, extending from Lake Champlain south along the Hudson River to Long Island. Two inset maps at top show Lake Champlain and the White Hills of the upper Connecticut Valley.
