At the Battle of Bunker Hill, approximately 1,500 American troops were engaged, primarily consisting of colonial militia and volunteer soldiers.

Although these forces were mostly untrained and had no formal military experience, they displayed impressive resilience and determination. The Americans established defensive positions on Breed's Hill, leveraging the terrain to counter the more seasoned British troops. Despite being outnumbered and confronting a professional army, the American forces managed to inflict considerable casualties on the British during the battle. This confrontation highlighted their capacity to hold their ground against a formidable adversary and represented a crucial turning point in the early phases of the Revolutionary War.
