In May 1915, the RMS Lusitania, then the world’s fastest liner, departed from New York. Seven days later she was torpedoed off the Irish coast with the loss of 1,198 lives. Suspected by the Germans of carrying clandestine munitions to Britain, the great ship steamed into a fatal encounter with the German submarine U-20. One of the largest naval disasters in history, it was a factor in bringing America into the First World War. Patrick O’Sullivan presents the complete story of the Lusitania affair, exploring the cover-ups and the theories on what caused the baffling second explosion. His meticulous research reveals the most compelling explanation to date. This is a fascinating account of one of the First World War’s most reported-on atrocities.
Room 40 at Admiralty House, London, was the hub of British Naval Intelligence. Tracking German Navy units was one of the main efforts of Room 40. A large amount of the Wireless Telegraphy (W/T) traffic from, to and between submarines in the North Sea and the Atlantic was regularly intercepted and deciphered by the British. Once decoded, this intelligence was passed directly on to the upper echelons of the Admiralty; namely:First Sea Lord Jacky Fisher, First Lord Winston Churchill and Admiral Oliver. Those three men needed to be fully aware of the very latest intelligence updates, particularly updates on the positions of German U-boats. These were obtained by Naval Intelligence from Room 40’s wireless intercepts,from sighting reports and from the reports of sinking's. Ultimately, it was those three men who made the operational decisions.
