Why was the Battle of Bunker Hill a turning point in the war?

The Battle of Bunker Hill, fought on June 17, 1775, marked a significant turning point in the American Revolutionary War by demonstrating the determination and resilience of colonial forces against British troops. Despite ultimately being a tactical victory for the British, the heavy casualties they suffered galvanized colonial resolve and bolstered support for the revolutionary cause. The battle also dispelled any notions that the British would easily suppress the rebellion, encouraging more colonists to join the fight for independence. This shift in perception helped solidify the formation of the Continental Army and laid the groundwork for future military engagements.
