From Wikipedia Isle of Man During World War I the British government interned male citizens of the Central Powers, principally Germany, Austria-Hungary and Ottoman Turkey.[83] They were held mainly in internment camps at Knockaloe, close to Peel, and a smaller one near Douglas. During World War II, about 8,000 people were interned in Britain, many being held in the same camps at Knockaloe and Douglas on the Isle of Man. The internees included enemy aliens from the Axis Powers, principally Germany and Italy.[84] Initially, refugees who had fled from Germany were also included, as were suspected British Nazi sympathisers such as British Union of Fascists leader Oswald Mosley. The British government rounded up 74,000 German, Austrian and Italian aliens. Within 6 months the 112 alien tribunals had individually summoned and examined 64,000 aliens, and the vast majority were released, having been found to be "friendly aliens" (mostly Jews); examples include Hermann Bondi and Thomas Gold and later members of the Amadeus Quartet. British nationals were detained under Defence Regulation 18B. Eventually only 2,000 of the remainder were interned. Initially they were shipped overseas, but that was halted when a German U boat sank the SS Arandora Star in July 1940 with the loss of 800 internees, though this was not the first loss that had occurred. The last internees were released late in 1945, though many were released in 1942. In Britain, internees were housed in camps and prisons. Some camps had tents rather than buildings with internees sleeping directly on the ground. Men and women were separated and most contact with the outside world was denied. A number of prominent Britons including writer H. G. Wells campaigned against the internment of refugees. See also: Defence Regulation 18B
