This image depicts George Washington leading the Continental Army to Valley Forge in 1777.
The Continental Army was formed during the war to win independence from Great Britain. It was formed of colonists and militias form other independent countries. All 13 original states contributed soldiers to the army. Interestingly the enlistment age was only 16yrs (15yrs with parental consent!) The army’s base was Valley Forge where the army is shown to be heading in picture. After the Treaty of Paris (1783) the army was disbanded due to the war being won, however it is possible that the remains of the continental army may have formed the beginning of the United States Army.
