During the Second World War the whaling stations were closed excepting Grytviken and Leith Harbour. Most of the British and Norwegian whaling factories and catchers were destroyed by German raiders, while the rest were called up to serve under Allied command. The resident British Magistrates (W. Barlas and A.I. Fleuret) attended to the island's defence throughout the War. The Royal Navy armed the merchant vessel "Queen of Bermuda" to patrol South Georgian and Antarctic waters, and deployed two four-inch (102 mm) guns at key locations protecting the approaches to Cumberland Bay and Stromness Bay, i.e. to Grytviken and Leith Harbour respectively. These batteries (still present) were manned by volunteers from among the Norwegian whalers who were trained for the purpose.
