"Baye de la Delaware avec les Ports, Sondes, Dangers, Bancs &c. depuis les Caps Jusqu'a Philadelphie…", Le Rouge, George Louis

French derivative of the important Revolutionary War chart by Joshua Fisher. This was a plan of the bay and river that was originally published in 1775 to assist pilots in bringing ships into Philadelphia. A list of pilots and masters who believe the chart would help 'safe navigation' in the bay is in a box at the upper left and a tide table is at the lower left. The map is filled with sailing instructions, soundings and notes on hazards. This uncommon and accurate map, published by le Rouge, was intended for use by the French military, merchants, and politicians.
