The Battle of Germantown was a major engagement in the Philadelphia campaign of the American Revolutionary War. It was fought on October 4, 1777, at Germantown, Pennsylvania, between the British Army led by Sir William Howe, and the American Continental Army under George Washington.
After defeating the Continental Army at the Battle of Brandywine on September 11, and the Battle of Paoli on September 20, Howe outmaneuvered Washington, seizing Philadelphia, the capital of the United States, on September 26. Howe left a garrison of some 3,000 troops in Philadelphia, while moving the bulk of his force to Germantown, then an outlying community to the city. Learning of the division, Washington determined to engage the British. His plan called for four separate columns to converge on the British position at Germantown. The two flanking columns were composed of 3,000 militia, while the center-left, under Nathanael Greene, the center-right under John Sullivan, and the reserve under Lord Stirling were made up of regular troops. The ambition behind the plan was to surprise and destroy the British force, much in the same way as Washington had surprised and decisively defeated the Hessians at Trenton. In Germantown, Howe had his light infantry and the 40th Foot spread across his front as pickets. In the main camp, Wilhelm von Knyphausen commanded the British left, while Howe himself personally led the British right.
A heavy fog caused a great deal of confusion among the approaching Americans. After a sharp contest, Sullivan's column routed the British pickets. Unseen in the fog, around 120 men of the British 40th Foot barricaded the Chew House. When the American reserve moved forward, Washington made the decision to launch repeated assaults on the position, all of which failed with heavy casualties. Penetrating several hundred yards beyond the mansion, Sullivan's wing became dispirited, running low on ammunition and hearing cannon fire behind them. As they withdrew, Anthony Wayne's division collided with part of Greene's late-arriving wing in the fog. Mistaking each other for the enemy, they opened fire, and both units retreated. Meanwhile, Greene's left-center column threw back the British right. With Sullivan's column repulsed, the British left outflanked Greene's column. The two militia columns had only succeeded in diverting the attention of the British, and had made no progress before they withdrew.
Despite the defeat, France, already impressed by the American success at Saratoga, decided to lend greater aid to the Americans. Howe did not vigorously pursue the defeated Americans, instead turning his attention to clearing the Delaware River of obstacles at Red Bank and Fort Mifflin. After unsuccessfully attempting to draw Washington into combat at White Marsh, Howe withdrew to Philadelphia. Washington, his army intact, withdrew to Valley Forge, where he wintered and re-trained his forces.
The Philadelphia campaign had begun badly for the Americans. Washington's Continental Army suffered a string of defeats at Cooch's Bridge,[6] Brandywine,[7] and Paoli. After inflicting a stinging defeat on Anthony Wayne's division at Paoli on September 20,[8] the British army marched north to Valley Forge then west to the French Creek bridge.[9] At this point, Howe's right wing faced Fatland Ford on the Schuylkill River near Valley Forge while the left wing was opposite Gordon's Ford at French Creek and the left center faced Richardson's Ford. The American army defended all these Schuylkill crossings, plus one farther downstream at Swede's Ford[10] near Norristown.[11] On September 22, a small British force under Sir William Erskine feinted north and another force mounted a demonstration at Gordon's Ford.[12] Howe's moves convinced Washington that the British commander was trying to seize his supply base at Reading and turn his right flank. Washington moved north, but in the night of September 22–23, the British army reversed direction.[13] They crossed the Schuylkill at Fatland and Richardson's Fords without opposition, and after a brief rest, headed downstream toward Swede's Ford where the American militia abandoned three cannons.[12]
Charles Cornwallis subsequently seized Philadelphia for the British on September 26, dealing a blow to the revolutionary cause. Howe left a garrison of 3,462 men to defend the city, moving the bulk of his force north, some 9,728 men, to the outlying community of Germantown.[2] With the campaigning season drawing to a close, Howe determined to locate and destroy the main American army. Howe established his headquarters at the Stenton Mansion, the former country home of James Logan.
Despite having suffered successive defeats, Washington saw an opportunity to entrap and decisively defeat the divided British army. He resolved to attack the Germantown garrison, as the last effort of the year before entering winter quarters. His plan called for a complex, ambitious assault; four columns of troops were to assail the British garrison from different directions, at night, with the goal of creating a double-envelopment. Washington's hope was that the British would be surprised and overwhelmed much how the Hessians were at Trenton.
Germantown was a hamlet of stone houses, spreading from what is now known as Mount Airy on the north, to what is now Market Square in the south.[14] Extending southwest from Market Square was Schoolhouse Lane, running 1.5 miles (2.4 km) to the point where Wissahickon Creek emptied from a steep gorge, into the Schuylkill River. Howe had established his main c
