Cause

Following his defeat at the Battle of Germantown, Washington encamped the Continental Army north of British-occupied Philadelphia. In early November 1777, he established an entrenched position along the Wissahickon Creek and Sandy Run, monitoring British movements and awaiting developments before winter.

Event

On December 4, 1777, British commander Gen. Sir William Howe led a substantial force out of Philadelphia in a final bid to destroy the Continental Army before winter. Over four days, a series of skirmishes occurred around Whitemarsh Township, but Howe failed to draw Washington into a decisive engagement and withdrew his forces back to Philadelphia.

Consequence

With the British safely back in Philadelphia, Washington marched the Continental Army to winter quarters at Valley Forge, ending the 1777 campaign season. Howe's failure to neutralize the American forces left Washington free to regroup and rebuild his army through the winter months.
