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, which has become a symbol of perseverance and sacrifice in the American Revolutionary War. The encampment at Valley Forge, located approximately 18 miles northwest of Philadelphia, was marked by extreme cold, food shortages, and inadequate supplies. Despite these challenging conditions, the time spent at Valley Forge was crucial for the Continental Army's development. It was during this winter that the troops received vital training and discipline from figures like Baron von Steuben, which significantly enhanced their effectiveness in battle.

The location’s strategic importance, combined with the trials faced by the soldiers, instilled a sense of resilience and unity within the army. Additionally, Valley Forge became an emblematic moment that encapsulated both the suffering and the resolve of the American soldiers in their quest for independence. In contrast, the other choices do not reflect the same significance in terms of hardship experienced by Washington's troops during the winter months of 1777 to 1778.
