The State Library will be closed Wednesday, March 17 in observance of Evacuation Day. On this day in 1776 the British Redcoats ended their occupation of Boston early in the American Revolutionary War. The siege of Boston came to a close when the Continental Army, under George Washington, fortified Dorchester Heights with cannons captured at Ticonderoga. The British forces withdrew from Dorchester Heights to Nova Scotia as depicted in this engraving.
