The Isle of Man, relatively isolated from the British mainland and with a useful amount of holiday accommodation, was used to provide housing for the "Alien Civilians" (as it had in World War I). There were also efforts to move internees to Canada. In July, 1940, the "Arandora Star" was torpedoed by a German U-boat and sunk while transporting Italian and German aliens to North America; 743 died. The 813 surviving prisoners were subsequently included in the 2,500 men transported by HMT "Dunera" for internment in Australia.
