Battle Of Fort Beausejour
The Battle of Fort Beauséjour marked the opening of a British offensive in the French and Indian War (the North American theater of the Seven Years' War). Beginning June 3, 1755, a British army under Lieutenant-Colonel Robert Monckton staged out of nearby Fort Lawrence, besieged the small French garrison at Fort Beauséjour with the goal of opening the Isthmus of Chignecto to British control. After two weeks of siege, Louis Du Pont Duchambon de Vergor, the fort's commander, capitulated on June 16.
The British formed an aggressive plan of operations for 1755. General Braddock was to lead the expedition to Fort Duquesne, while Massachusetts provincial governor William Shirley was given the task of fortifying Fort Oswego and attacking Fort Niagara, Sir William Johnson was to capture Fort St. Frédéric (at present-day Crown Point, New York), and Lieutenant Colonel Robert Monckton was to capture Fort Beauséjour on the frontier between Nova Scotia and Acadia.
