"The wireless cabins of ships became prime targets. In 1917 a German submarine attacked the SS Benledi and focused its fire on the ship's wireless room, as its Marconi operator tried to reach an American warship for help. The warship arrived, the submarine fled. Afterward the Benledi's captain went to the wireless cabin and found the operator still in his chair, everything in place, save for one macabre detail. His head was missing. In all, the war would kill 348 Marconi operators, most at sea."
