lack of civilian shipping. For the first time, cables became targets of warfare in themselves. Eastern Telegraph, the British Royal Navy, and the General Post Office collaborated on cutting all cable links between Germany and North America. The Germans temporarily disabled both the Pacific Cable and the cable across the Indian Ocean, by attacking island stations in each ocean. However, the most spectacular event of the first "cable war" came in 1917, when, following the United States' entry into the war, the German cable that had been cut three years before was lifted out of its position between New York and Emden, Germany, moved to a new position between Nova Scotia and Cornwall, and taken over by the British government as a prize of war, to be operated by the General Post Office. In 1920, the government decided to keep this cable, despite U.S. protests, and to purchase a second line, the two together being renamed Imperial Cable. With increasing competition from companies using radio communications, such as Marconi's Wireless Telegraph Company, it was decided in 1928 to merge the communications methods of the British Empire into one operating company, initially known as the Imperial and International Communications Ltd, and from 1934 as Cable and Wireless Limited. The firm formed subsidiary corporations in various countries, such as the Indian Radio and Cable Communications Company in 1932, designed to oversee India's external communications with other countries. World War II revived the 'cable war' of 1914–1918. In 1939, German-owned cables across the Atlantic were cut once again, and, in 1940, Italian cables to South America and Spain were cut in retaliation for Italian action against two of the five British cables linking Gibraltar and Malta. Electra House, the company's head office and central cable station, was damaged by German bombing in 1941. However, the company made a considerable contribution to the Allied war effort, supplying, for instance, the wireless equipment with which the North African campaign was conducted in 1942, and sending staff, in army uniforms marked with Telcon flashes, into several campaigns, starting in Italy in 1943. Following the Labour Party's victory in the 1945 general election, the government announced its intention to nationalise Cable and Wireless, which was carried out in 1947. While the company would remain in being as a government-owned company, continuing to own assets and operating telecommunication services outside the UK, all assets in the UK were
