Operation Chastity was a World War II plan by the Allies to seize Quiberon Bay, France, enabling the construction of an artificial harbor to support Allied operations in Northern France in 1944. The artificial harbor was not developed, as the US VIII Corps failed to capture German-held areas that threatened the port. By the end of August 1944, Allied forces had captured all of Brittany except for the critical areas, preventing the further development of the operation. Following the capture of Antwerp and its port facilities in early September 1944, Operation Chastity was officially cancelled on 7 September. The non-completion and eventual cancellation of Operation Chastity exacerbated strains on the Allied logistical system, may have prevented an Allied victory over Germany in 1944, and has been described as "the critical error of World War II", although other historians believe that priority was rightly given to the pursuit of the routing German forces.

The Battle of Quiberon Bay (known as Bataille des Cardinaux in French) was a decisive naval engagement during the Seven Years' War. It was fought on 20 November 1759 between the Royal Navy and the French Navy in Quiberon Bay, off the coast of France near Saint-Nazaire. The battle was the culmination of British efforts to eliminate French naval superiority, which could have given the French the ability to carry out their planned invasion of Great Britain. A British fleet of 24 ships of the line under Sir Edward Hawke tracked down and engaged a French fleet of 21 ships of the line under Marshal de Conflans. After hard fighting, the British fleet sank or ran aground six French ships, captured one and scattered the rest, giving the Royal Navy one of its greatest victories, and ending the threat of French invasion for good. The battle signalled the rise of the Royal Navy in becoming the world's foremost naval power, and, for the British, was part of the Annus Mirabilis of 1759.
