What were the exact dates of the Continental Army’s main Valley Forge encampment?

The Continental Army’s main Valley Forge encampment lasted from December 19, 1777, to June 19, 1778.

George Washington led the army into Valley Forge, Pennsylvania, after British forces captured Philadelphia during the 1777 campaign. The site was close enough to monitor British movements but far enough from Philadelphia to provide a defensible winter position.

The army built log huts and faced severe shortages of food, clothing, and supplies. Disease killed many soldiers, while poor logistics created serious hardship. The popular image of constant deep snow is misleading: the winter was difficult, but the best-known accounts emphasize shortages and disease as much as weather.

Valley Forge was also a period of military reorganization and training. Baron Friedrich Wilhelm von Steuben helped improve drill and discipline, contributing to a more effective Continental Army. When the army left in June 1778, it was better prepared for the campaigns that followed.
