The Battle of Bunker Hill was a battle fought on June 17, 1775, during the Siege of Boston in the early stages of the American Revolutionary War. The battle is named after Bunker Hill in Charlestown, Boston, which was peripherally involved in the battle, and was the original objective of both the colonial and British troops, though the vast majority of combat took place on the adjacent Breed’s Hill.
Bunker Hill Day, observed every June 17, is a legal holiday in Suffolk County, Massachusetts (which includes the city of Boston), as well as Somerville in Middlesex County. Prospect Hill, site of colonial fortifications overlooking the Charlestown Neck, is now located in Somerville, which was previously part of Charlestown. State institutions in Massachusetts (such as public institutions of higher education) located in Boston also celebrate the holiday. However, the state’s FY2011 budget requires that all state and municipal offices in Suffolk County be open on Bunker Hill Day and Evacuation Day.
On June 16 and 17, 1875, the centennial of the battle was celebrated with a military parade and a reception featuring notable speakers, among them General William Tecumseh Sherman and Vice President Henry Wilson. It was attended by dignitaries from across the country. Celebratory events also marked the sesquicentennial (150th anniversary) in 1925 and the bicentennial in 1975.
