This is true, sorry if I’m wrong
I currently searched up the question your looking for and this is what I somewhat found
Answer:
In December, 1777, General George Washington moved the Continental Army to their winter quarters at Valley Forge. By the time the army marched into Valley Forge on December 19, they were suffering not only from cold, hunger, and fatigue, but from low morale in the wake of the disastrous Philadelphia Campaign.
You, my friend need to pay attention <3
