The Patriots Strength

George Washington was a key for Patriots because of his knowledge and strategies. Washington sustained the Patriots by hardships.
It is undeniable that the Patriots were a small army, but committed as well. 
One good thing that helped the colonists have peace, was the fact that their wives approved the idea of them going to war, this as small as it seems, was extremely important to the family men, for they could fight and focus on their missions.

Wars are the main economic resource because things are so lack, they were being sold really expensively. This was called Profiteering.
Money was called the continental, and if farmers sold land to Patriots they would get paid with continentals, and if they sold the land to the British, they got paid with gold which was by far more important, but some farmers were loyal to the Patriots though. 

Deborah Sampson got paid to to serve with the military with a pension, and some women would even followed their husbands to wars and they helped cleaning, washing, and firing arms as well. 
Mary Hays, who was also known as Molly Pitcher, gave water to the soldiers at the wars.
