This detailed Revolutionary War-era sea chart was prepared by the French Navy, under the direction Antoine de Sartine, the Secretary of State for the Navy, upon their entry into the war on the American side. The chart covers New York Harbor and vicinity. It shows navigational soundings, channels, rocks and shoals, the lighthouse at Sandy Hook, and towns on the Jersey shore. The text in the Advertissement is a French translation of a letter from the British commander, General Howe, describing an engagement with Washington in 1778 at Sandy Hook. It includes the seal of the Depot de la Marin and a price of Trois Livres below the neatline at bottom right.

This chart was originally issued on a sheet with an accompanying chart of the Delaware River.
