Today, Germantown is a busy neighborhood in Philadelphia. On October 4, 1777, it was a small village on the outskirts of the colonial capital whose surrounding fields and streets witnessed one of the largest battles of the American Revolution. The bloody battle represented George Washington's attempt to recapture Philadelphia but has long been overshadowed by better-known events like Brandywine, Saratoga, and Valley Forge.

General Sir William Howe launched his campaign to capture Philadelphia in late July 1777, with an army of 16,500 British and Hessian soldiers aboard a 265-ship armada sailing from New York. Six difficult weeks later, Howe's expedition landed near Elkton, Maryland, and moved north into Pennsylvania. Washington's rebel army did all it could to harass Howe and fought and lost a major battle at Brandywine on September 11. Philadelphia fell to the British.

On October 4, obscured by darkness and a heavy morning fog, Washington launched a surprise attack on the British garrison at Germantown. His early attack found initial success and drove the British legions before him. The recapture of the colonial capital seemed within Washington's grasp until poor decisions by the American high command brought about a reversal of fortune and a clear British victory.
