The Americans were able to fight right on their soil. This means that they knew which ways to go through, and how to get somewhere easier. On the other hand, the British were on foreign land that they could not easily navigate through.
Untrained and unorganized military unit
I'm not sure where to stand.
The Continental Army was led by good leaders including George Washington and The Marquis de Lafayette. These two commanders had already had experience in battle and were able to train soldiers as well. Washington had served the British in the French and Indian War, so he knew how the British were going to command their troops.
The French had been a great help to the Continental Army when deciding to join in on the fight. The French were supportive of the Revolution happening in the Thirteen Colonies. They help by giving the Continental Army loans, troops, and naval support. Without the help of the French there would've been no way the Americans would have won.
I want to quit...it's too cold and I'm starving!
The Continental Army was made up of the average colonists from the colonies. There were farmers, former slaves, and any other men who joined. Many of the men did not have military experience especially with a gun. They had no uniforms or weapons that weren't bought by themselves.
Where do I aim?
The British greatly outnumbered the Americans by many numbers. The number would go down during the winter times of the war. George Washington had less than 20,000 soldiers for him at one time. Some troops would even leave to go back home.
The Continental army didn't have much weapons such as guns and gunpowder to go with it. Many wore normal clothing on for on and off the battlefield. One of the main things was the lack of food which caused many soldiers to leave the army. For example, at Valley Forge the soldiers were starving and freezing causing them to want to give up.
