On what date was the Battle of Bunker Hill fought during the Siege of Boston?

The Battle of Bunker Hill was fought on June 17, 1775, during the Siege of Boston.

Colonial forces occupied positions on the Charlestown Peninsula, building their main redoubt on nearby Breed’s Hill rather than on Bunker Hill itself. British troops attacked the fortifications in repeated assaults and captured the peninsula after the colonists ran short of ammunition and withdrew.

Although the battle is usually called Bunker Hill, most of the fighting occurred on Breed’s Hill. The British won the field but suffered heavy losses, including more than 1,000 killed or wounded. The costly result demonstrated that colonial forces could resist experienced British regulars in a major engagement.

The battle took place early in the American Revolutionary War, shortly after the fighting at Lexington and Concord. Its date, location, and confusing hill names make it a particularly useful fact for understanding the opening military phase of the history celebrated by America250.
