In late August 1777, after a distressing 34-day journey from Sandy Hook on the coast of New Jersey, a Royal Navy fleet of more than 260 ships carrying some 17,000 British troops under the command of British General Sir William Howe landed at the head of the Elk River, on the northern end of the Chesapeake Bay near present-day Elkton, Maryland (then known as Head of Elk), approximately 40–50 miles (60–80 km) southwest of Philadelphia. Unloading the ships proved to be a logistical problem because the narrow river neck was shallow and muddy.
