Background and detail
Background. King George's War (1744–1748) was the North American theater of the War of the Austrian Succession. Following the formal declaration of war in March 1744, French forces at Louisbourg began hostilities. In 1745, Massachusetts Governor William Shirley secured legislative support for an expedition to capture the fortress.
The Siege. British colonial forces, supported by Commodore Warren's fleet, conducted a landward siege of Louisbourg. After 47 days of bombardment and siege operations, the French garrison capitulated on June 28, 1745. The capture was a major strategic achievement for the British colonies during the conflict.
