The Raid on Canso was an attack by French forces from Louisbourg on the British outpost Fort William Augustus at Canso, Nova Scotia shortly after war declarations opened King George's War. The French raid was intended to boost morale, secure Louisbourg's supply lines with the surrounding Acadian settlements, and deprive Britain of a base from which to attack Louisbourg. While the settlement was utterly destroyed, the objective failed, since the British launched an attack on Louisbourg in 1745, using Canso as a staging area.
