- On 28 March 1942, British forces launched one of the most daring operations of the Second World War. Now known as Operation Chariot was an attack on the docks at St Nazaire in German-occupied France. It was a feat of cunning and daring that helped to shape the war at sea. St Nazaire was targeted because the loss of its dry dock would force any large German warship in need of repairs, such as Tirpitz, sister ship of Bismarck, to return to home waters by running the gauntlet of the Home Fleet of the Royal Navy and other British forces, via the English Channel or the GIUK gap.
