Siege Of Louisbourg
The Siege of Louisbourg was a pivotal battle of the French and Indian War (the North American theater of the Seven Years' War) in 1758 which ended the French colonial era in Atlantic Canada and led directly to the loss of Quebec in 1759 and the remainder of French North America the following year.
Colonel Monckton, in the only real British success that year, successfully captured Fort Beauséjour in June 1755, cutting the French fortress at Louisbourg off from land-based reinforcements. The victory was tarnished by the decision of Nova Scotia's Governor Charles Lawrence afterwards to order the deportation of the French-speaking Acadian population from the area. Monckton's forces, including companies of Rogers' Rangers, forcibly removed thousands of Acadians, chasing down many who resisted, and sometimes committing atrocities. The Acadian resistance, in concert with native allies, including the Mi'kmaq, was sometimes quite stiff, with ongoing frontier raids. The only clash of any size was the 1757 Battle of Bloody Creek near Annapolis Royal.
