The six-month encampment of General George Washington's Continental Army at Valley Forge in the winter of 1777-1778 was a major turning point in the American Revolutionary War. The defeats had led some members of the Continental Congress to want to replace Washington, believing he was incompetent.
In January 1777, Washington had ordered mass inoculation of his troops, but a year later at Valley Forge, smallpox broke out again. An investigation uncovered that 3,000–4,000 troops had not received inoculations, despite having long-term enlistments. Washington's men were sick from disease, hunger, and exposure. The Continental Army camped in crude log cabins and endured cold conditions while the Redcoats warmed themselves in colonial homes. The patriots went hungry while the British soldiers ate well.
