On June 17, 1775, the Battle of Bunker Hill took place. An excerpt from the article:
"On June 17, 1775, early in the Revolutionary War (1775-83), the British defeated the Americans at the Battle of Bunker Hill in Massachusetts. Despite their loss, the inexperienced colonial forces inflicted significant casualties against the enemy, and the battle provided them with an important confidence boost during the Siege of Boston (April 1775-March 1776). Although commonly referred to as the Battle of Bunker Hill, most of the fighting occurred on nearby Breed’s Hill."
