The American colonists who actually fought in the war were called "minutemen" or "militiamen" if they belonged to their local Militia.The minutemen could supposedly be ready for battle at a minute's notice.They served as the main source against the British in the early days of war, and despite having little formal training or experience, held up well against the superior battle tactics of the Redcoats. During the battle of Lexington-Concord, the minutemen lost about a quarter of the men that the British lost. The colonists would have won the battle of Bunker Hill, but they ran low on ammo and had to surrender. They had several advantages over the British, however. For example, they were much better aquainted with their surroundings and knew multiple ways to reach any British fortification. They also believed in the cause of freedom, lending spirit to their attacks.
