Position of the Combined Army at Philipsburg from July 6 to August 19
This pen-and-ink and watercolor manuscript map is attributed to cartographer Louis-Alexandre Berthier (1753‒1815), who served with the Marquis de Lafayette (1757–1834) and the Comte de Rochambeau during the American Revolution and who later was one of Napoleon’s marshals. Berthier stayed in America from September 30, 1780 until December 24, 1782 and accompanied the combined French-American army on its march from New England to Yorktown, Virginia and its return march to Boston. This map depicts the Philipsburg, New York camp that the two armies occupied from July 6 to August 19, 1781. At the time, a proposed French-American attack on British-occupied New York was still under consideration. The combined army instead would feign an attack on New York City and then march to Yorktown, where the Siege of Yorktown would effectively conclude the war. The map covers the area from Tarrytown to Staten Island in New York. The dense settlements at the southern tip of Manhattan Island and across the East River in Brooklyn are marked. The map shows towns, houses, roads, rivers, bridges, and relief. Some units are incorrectly identified. A legend on the right side provides an explanatory key to the location of French and American camps, the different military units, the quarters of Washington and Rochambeau, a French hospital, and fortifications. A note on the legend indicates that the army consisted of 5,000 French and 4,000 American soldiers. The map is from the Rochambeau Collection at the Library of Congress, which consists of 40 manuscript maps, 26 printed maps, and a manuscript atlas that belonged to Jean-Baptiste-Donatien de Vimeur, comte de Rochambeau (1725‒1807), commander in chief of the French expeditionary army (1780‒82) during the American Revolution. Some of the maps were used by Rochambeau during the war. Dating from 1717 to 1795, the maps cover much of eastern North America, from Newfoundland and Labrador in the north to Haiti in the south. The collection includes maps of cities, maps showing Revolutionary War battles and military campaigns, and early state maps from the 1790s.
