oct 4, 1777 - The Battle of Germantown
The campaign in Philadelphia had begun quite badly for the American forces. Washington and the Continental Army had suffered successive defeats at the Battle of Brandywine and the Battle of Paoli that left Philadelphia defenseless. After the seizure of the revolutionary capital by Charles Cornwallis on September 26, 1777, William Howe left 3,462 men to defend it and moved 9,728  men to Germantown, 5 miles (8.0 km) north, determined to locate and destroy the American forces. Howe established his headquarters at Stenton, the former country home of James Logan.
