Carte réduite des côtes orientale de l'Amérique Septentrionale contenant partie du Nouveau Jersey, la Pen-sylvanie, le Mary-land, la Virginie. . .

A revolutionary war map of the American coast from Delaware Bay to northern Florida.
This Revolutionary War chart was issued by the Depot de la Marine specifically for the use of French vessels and was published at the time of France's entry into the war. Unlike most nautical charts, the map includes very good inland detail. Cities, towns, and forts are identified, rivers are named and elevation is shown via hachuring.
In keeping with its principal use, however, ports along the coasts are identified and soundings are given. Dated 1778, the map was first issued in the 1780 edition of the Neptune Americo-Septentrional.

The chart extends from Delaware Bay and Philadelphia south through much of Georgia to Amelia Island and St. Johns River. It provides excellent detail along the coast, particularly in the Chesapeake Bay. Surprisingly, it also provides great detail inland to the Appalachians and extends west to Fort Necessity and the Ohio River in Western Virginia.
The map shows early county names throughout the region, as well as early roads, Indian tribes, towns, mountains, and rivers. Numerous native tribes are noted and the location of the Catawba Indians Catawbaw Town is shown south of Charlotte, SC. Two Quaker meeting houses are shown east of Salem, NC.
Prepared under the direction of Antoine Sartine, Minister of Marine in Paris for the use of the French Navy when they came over to America to help in the Revolutionary War.First state.

The Dépôt de la Marine, known more formally as the Dépôt des cartes et plans de la Marine, was the central charting institution of France. The centralization of hydrography in France began in earnest when Jean-Baptiste Colbert became First Minister of France in 1661.
Under his watch, the first Royal School of Hydrography began operating, as did the first survey of France’s coasts (1670-1689). In 1680, Colbert consolidated various collections of charts and memoirs into a single assemblage, forming the core of sources for what would become the Dépôt.
The Dépôt itself began as the central deposit of charts for the French Navy. In 1720, the Navy consolidated its collection with those government materials covering the colonies, creating a single large repository of navigation. By 1737, the Dépôt was creating its own original charts and, from 1750, they participated in scientific expeditions to determine the accurate calculation of longitude.
In 1773, the Dépôt received a monopoly over the composition, production, and distribution of navigational materials, solidifying their place as the main producer of geographic knowledge in France. Dépôt-approved charts were distributed to official warehouses in port cities and sold by authorized merchants. The charts were of the highest quality, as many of France’s premier mapmakers worked at the Dépôt in the eighteenth century, including Philippe Bauche, Jacques-Nicolas Bellin, Rigobert Bonne, Jean Nicolas Buache, and Charles-François Beautemps-Beaupré.

The Dépôt continued to operate until 1886, when it became the Naval Hydrographic Service. In 1971, it changed names again, this time to the Naval and Oceanographic Service (SHOM). Although its name has changed, its purpose is largely the same, to provide high-quality cartographic and scientific information to the France’s Navy and merchant marine.
