The Capture of Vigilant was an incident in May 1745 of the naval warfare of King George's War. British forces captured the French vessel Vigilant off Nova Scotia.
It involved Commodore Warren in HMS Superb (60 guns), Captain Durell in HMS Eltham (40 guns), Captain Calmady in HMS Launceston, Captain Douglas in HMS Mermaid and Captain John Rous of HMS Shirley Galley who fought the French ship Vigilant (64 guns) off Louisbourg. Douglas in Mermaid (40 guns) engaged the French ship. John Rous in Shirley Galley was the first to fire, giving the ship several broadsides into the stern. Captain Durell was next to give a broadside. The commodore got alongside the ship - they fired briskly, tearing the rigging and sails to pieces. Fog settled in and Vigilant got away. In the morning, Vigilant was visible and clearly wrecked. The British took 100 French sailors prisoner to Boston.[2]
