This manuscript map, from the American Revolutionary War, was drawn by a British cartographer. It illustrates military operations in the area around Elkton, Maryland, and Valley Forge and Philadelphia in Pennsylvania. The map documents the period in which the British sailed south, arriving on the west side of the Elk River on August 25, 1777, until the British army took possession of Philadelphia on September 26. The map shows in detail military engagements that took place during that time, including the Battle of Brandywine on September 9-11, and denotes roads, ferry and river crossings, marching routes, taverns, and place names.
