Evacuation Day Boston March 17, 1776 – American Revolution

Boston, MA: March 17 1776 –  Evacuation Day. British General William Howe, whose garrison and navy were threatened by these positions, was forced to decide between attack and retreat. To prevent what could have been a repeat of the Battle of Bunker Hill, Howe decided to retreat, withdrawing from Boston to Nova Scotia on March 17, 1776. Evacuation Day is a holiday observed on March 17 in Suffolk County, Massachusetts (which includes the cities of Boston, Chelsea, and Revere, and the town of Winthrop) and also by the public schools in Somerville, Massachusetts. The holiday commemorates the evacuation of British forces from the city of Boston following the Siege of Boston, early in the American Revolutionary War. wiki
