Valley Forge was the winter encampment of the Continental Army from 19 December 1777 until 18 June 1778, during one of the most difficult winters of the American Revolutionary War (1775-1783). Despite being undersupplied, underfed, and plagued with disease, the Continental Army underwent significant training and reorganization at Valley Forge, emerging as a much more disciplined and effective fighting force.
The Philadelphia Campaign
On 19 December 1777, the exhausted and starving soldiers of the Continental Army staggered into Valley Forge, Pennsylvania, a location about 18 miles (29 km) northwest of Philadelphia at the confluence of the Valley Creek and the Schuylkill River. It had been a long and difficult campaign. Four months earlier, they had raced down from New Jersey to defend the US capital of Philadelphia from the British army, only to be outflanked and defeated at the Battle of Brandywine (11 September). Following their victory, the British captured Philadelphia, which the Second Continental Congress had only just evacuated. The Continental Army regrouped and, on 4 October, retaliated with a surprise attack on a British garrison at the Battle of Germantown. Although the assault initially got off to a good start, a thick fog caused cohesion between American military units to break down, and the attack quickly lost momentum. When the British counterattacked, the undertrained Continental soldiers broke and fled. For the next two months, the two armies nervously maneuvered around one another. Although several bloody skirmishes were fought, neither side was eager to provoke another major battle.
Gradually, the temperatures dropped, and the bitter December winds signaled that it was time to suspend the campaign and enter winter quarters. The British army moved into Philadelphia, where the officers settled into the abandoned homes of the city's Patriot leaders and spent the winter attending lavish dinners, dancing at elegant balls, and courting Loyalist women. The Continental Army, meanwhile, marched to Valley Forge. The spot had been carefully chosen by the American commander-in-chief, General George Washington, for several reasons. First, its proximity to Philadelphia would allow the Americans to keep a close eye on the British army; attempts by the British to raid the surrounding Pennsylvanian countryside or to march for the town of York, the temporary seat of the Continental Congress, could quickly be challenged. Second, an encampment at Valley Forge would be easy to defend. The camp itself was to be situated on a large plateau surrounded by a series of hills and dense forests, creating a sort of natural fortress. Lastly, the location was beneficial because it was close to a supply of fresh water from the Valley Creek and Schuylkill River, and the abundance of nearby trees could easily be cut down for fuel or to build shelters.
Over 11,000 Continental soldiers filed into Valley Forge on that December day, accompanied by 500 women and children. They were certainly a disheveled lot. The many marches and countermarches they had needed to perform in the last several months had worn down their footwear; now, an estimated one out of every three Continental soldiers went entirely without shoes. Additionally, many soldiers lacked adequate coats to protect against the elements, particularly the incessant rain that had been falling all autumn. Many men owned only one shirt, while others did not even have a single shirt at all. It is unsurprising then that many of these exposed soldiers were already ill when they arrived at Valley Forge; out of the 11,000 men that arrived, only 8,200 were fit for duty.
The situation was made worse by a dangerous lack of food. At the beginning of the Valley Forge encampment, the army's commissary only had 25 barrels of flour, a small supply of salt pork, and no other stores of meat or fish. A lack of sufficient food and clothing was fairly typical of the army's supply department, which had often performed below expectations since its founding in 1775, but the chaos of the recent campaign had only made things worse. In its hurried evacuation from Philadelphia, Congress had failed to ensure the army's supply chain would remain unbroken, thereby contributing to the bareness of the army's food and clothing stores. Thus, it was clear from the start that the coming winter would be a challenging one.
