This Revolutionary War map was based on the chart Joshua Fisher made of Delaware Bay in 1756. The Fisher map is considered an important map of the bay and river in the eighteenth century. Joshua Fisher's early chart of Delaware Bay from the Sea-Coast to Reedy-Island was published during the French & Indian War, and was immediately suppressed by the Assembly, fearing that its falling into enemy hands would make Philadelphia a target of the French navy. Identifies the ship channels from Cape May and Cape James up the Delaware River past Salem Mass. Wilmington, Newcastle, and Chester to the small town of Philadelphia, Pennsylvania. The accompanying text includes an article updating the British public on the war in the colonies. It shows the bay and beyond to Philadelphia complete with place names and the location of navigation hazards along the waterway. Locates Cape May, Turtle Gut Inlet, Cape James, Egg Island, Salem, and much more. Two distance scales and the direction rose with fleur-de-lis orients north to the right. A large discolouration permeates the majority of the map element.
Covers from Maine to South Carolina and west to Lake Michigan. Relief shown pictorially. Title enclosed in simple double-lined box. A map of English colonies in America before the Revolutionary War. Some English names are present before they were later changed in favour of more nationalistic ones. Lake Michigan is considerably smaller in this map, and its connection to Lake Huron is more than 300 km to the north of where the map places it.
Tooley calls this a foundational map of North America and the first to revert to the southern part of California as a peninsula since the early 1600's. It uses outline color to depict the colonial possessions although the colors used are not consistent or explained between examined online copies of this exact state.
