The Dewees House is located just west of Washington's Headquarters in Valley Forge
In early 1777, the American Quarter Master General selected Valley Forge to serve as one of the Continental stores. Thousands of barrels of wheat and flour as well as tomahawks, horseshoes, and tools were moved into the Potts-Dewees forges and outbuildings.
In September, after the Battle of Brandywine, a British detachment headed for Valley Forge. Warned of their approach, a party of Dragoons along with Lt. Colonel Alexander Hamilton tried to ferry the stores across the Schuylkill, but did not get them across in time. The enemy was too swift and the American's had to retreat across the river leaving precious stores to be captured.
Two days later the main British army passed through, carrying off or destroying the supplies. The forge, sawmill, and several homes and outbuildings were set afire. Only ruins remained at the time of the encampment three months later.
On the stream bank to the right of the Dewees House stood the sawmill and gristmill. The iron forge was across the road to the left, with a diversion dam for water power.
