This detailed chart contains 'soundings and nautical observations taken by Captain Sir Andrew Snape Hammond of the Navy, and others'. It was composed and published for the use of pilotage by J.F.W. Des Barres Esq. June 1st 1779. The image is very strong with the land strongly hachured and the river features clearly marked. The three main shipping channels are shown up as far as Bombay Hook, as are other details such as oyster beds, sand flats, marshes and 'barrs'.
From the outset of the Revolutionary War, the British had recognized the importance of the major rivers, estuaries, harbors and ports of the southern middle states of the colonies, and had in many cases already started surveying them for navigation. These rivers posed a genuine, economic, and military threat to the British. The Delaware River split New Jersey and Maryland, and was the arterial link to Philadelphia; the Chesapeake River and all of the rivers therein provided links to all of the major towns and cities of Virginia; and the rivers and inlets of the Carolinas provided links to the slave and spice trade.
