Answer:
B.
Step-by-step explanation:
The time when the Continental Army of George Washington encamped the Valley Forge was the time of winter. They encamped the valley for six months in winters of 1777-1778. The conditions of the valley was notoriously cold. Because of the harsh cold, and lack of supply in provision, Washington's Army lost many soldiers.
From the thousand soldiers who encamped in the Valley, hundreds of them died of sickness. But the harsh conditions of the Valley proved like a training to the soldiers, because after coming out of the valley, they won the battle against the Britishers.
