A map of Yorktown, besieged by the French and Americans commanded by General George Washington (22 February 1732–14 December 1799) and Jean Baptiste Donatien de Vimeur, comte de Rochambeau (1725-1807), and surrendered by the British, commanded by Lieutenant-General Lord Charles Cornwallis (1738-1805). American War of Independence (1775-83). Oriented with north-north-east to top.

The siege of Yorktown lasted from 29 September to 19 October. About 9,000 British troops, including Germans, were besieged and defeated by a combined 19,000-strong French and American army.

This rare map has been described as a cornerstone document of American national heritage. Only twelve copies are known in the USA. It is the only known American survey of the culminating battle of the war, and shows the investiture of Yorktown, with the American trenches and ‘The Field where the British laid down their Arms’. The American forces are shown in blue, the French in yellow, and the British in red. It was advertised for sale in The New York Packet and the American Advertiser in March 1782.

The map was reproduced in 1825 by John Francis Renault and Benjamin Tanner; in about 1887 by the New England Historic Genealogical Society; 1976 by Meridian Gravure Company and again in 1981 by the United States Defense Mapping Agency.
