By December 1777, Washington was well aware that some members of the Continental Congress were questioning his leadership abilities. The Valley Forge site—located along trade routes and near farm supplies—was an attempt to balance Congress’ demands for a winter campaign against Philadelphia with the needs of his troops. It was common for armies at the time to withdraw to fixed camps during the winter, as the harsh weather made transportation of troops, arms and supplies extremely difficult.
The soldiers who marched to Valley Forge on December 19, 1777 were not downtrodden or desperate. Though they had been defeated in two key battles, and had lost Philadelphia to the British, Continental troops had often put themselves on the offensive, and proved themselves as skilled fighters against professional soldiers with superior numbers. They were certainly tired, and lacking in supplies, but these were not unusual circumstances in the life of a Continental soldier. Once the troops arrived at their winter camp site, military engineers directed the construction of some 2,000 huts laid out in parallel lines, forming a kind of city, along with miles of trenches, five earthen redoubts and a bridge over the Schuylkill River.
