Continental Army was very motivated to win this major battle for freedom
If YOU WANT TO WIN YOUR FREEDOM YOU WILL WIN THIS WAR!
The Continental army was so educated about where they was from that they were able to used something called guerilla warfare. Meaning while the British was retreating they would sneak attack them.
Since the Continental army had great/experienced leader they were able to make very smart decisions/strategies to win the most important battles of the war.
Very little manpower
WE HAVE NO MEN!
The Continental Army was very motivated to win this war because their freedom and their self government was on the line so they needed every motivational speech they can get from their leaders.
Very little source of weapons and supplies
Very few men were trained well enough to win or survive any battle while the British were well trained to survive all battles and wars. Most likely when the colonist face well trained soldiers they most likely will run away.
The continental army was short of qualified and capable men. General George Washington routinely had no more than 20,000 at a time and place.
Guns were very scarce and gunpowder was even more so. Ben Franklin suggested that the colonist should use bow n arrows. Food was very short and uniforms as well.
