What happened
After losing Philadelphia and fighting inconclusive battles at Brandywine and Germantown, Washington marched the Continental Army into winter quarters at Valley Forge, Pennsylvania, on 19 December 1777. As many as 12,000 Continentals, along with smaller numbers of Black and Native American soldiers, camped only twenty miles from British-occupied Philadelphia through a winter of cold, hunger, and disease that killed an estimated 2,000 soldiers, roughly one in six of the encampment. Washington himself called it "a dreary kind of place and uncomfortably provided." That spring, the Prussian volunteer officer Baron Friedrich von Steuben arrived and drilled the army in standardized tactics and marching formations, turning a ragged militia force into a more disciplined army before it broke camp on 19 June 1778.
Why it matters
Valley Forge is remembered less for combat than for survival and reform: von Steuben's training program gave the Continental Army a common drill book for the first time, improving its performance in the battles that followed. The winter also tested whether the army and the fragile alliance between Congress and the states could hold together through hardship, and it did.
