Where did Washington's troops endure a harsh winter from 1777 to 1778?

Washington's troops endured a harsh winter from 1777 to 1778 at Valley Forge. This encampment is significant in American history as it exemplified the challenges faced by the Continental Army, including severe weather conditions, lack of supplies, and food shortages. Despite the extreme hardships, this period became a transformative time for the troops; they received rigorous training under the guidance of Baron von Steuben, which helped them emerge as a more disciplined and effective fighting force. The struggle at Valley Forge highlighted not only the resilience of the troops but also the commitment of the Continental Congress and various states to support the army, illustrating the challenges and determination of the American Revolution. Other locations listed, such as Yorktown, Philadelphia, and Boston, were important in other contexts, but they were not the site of this particular winter encampment.
