This map was used by Jean Baptiste Donatien de Vimeur, comte de Rochambeau (1725-1807), when he was commander in chief of the French expeditionary army (1780-82) during the American Revolution. The maps from Rochambeau’s personal collection, cover much of eastern North America, and date from 1717 to 1795. The maps show Revolutionary-era military actions, some of which were published in England and France, and early state maps from the 1790s. Many of the items in this extraordinary group of maps show the importance of cartographic materials in the campaigns of the American Revolution as well as Rochambeau’s continuing interest in the new United States. Pen & ink and watercolor manuscript with watermarks. Relief shown by form lines and shading. Shows fortifications, fields of fire, and positions of French naval vessels. Oriented with north toward the upper right. Includes index to defenses.
