War service

At the outbreak of war in 1939, Winn volunteered for service as an interrogator of German prisoners. But he was soon assigned to the Admiralty's Submarine Tracking Room (part of the Operational Intelligence Centre – OIC), although he was still a civilian. Though new to the naval environment, he quickly came to understand U-boat tactics, and could frequently predict their actions. As a result, he was promoted to command the Tracking Room, as a temporary

. It is a measure of his ability that he received this rank and position without formal naval officer training, which was unprecedented at the time, and that he displaced his former superior. Winn's advancement was no surprise to his colleagues and he extended his influence within the OIC. During the German attacks on shipping off the U.S. coast, Winn was sent to

intelligence. From ULTRA and his observations of U-boat movements, he deduced that German codebreakers had cracked the BAMS ( Broadcast to Allied Merchant Ships) code used by the Admiralty for convoy operations. In 1943 he eventually convinced the Admiralty to make the necessary revisions to BAMS. After the war, captured records showed that the German Navy's '' Beobachtungsdienst'' (Signals Intelligence Service) had been reading BAMS since the start of the conflict. In 1944, the Germans equipped the U-boats with snorkels, so that they could operate without surfacing. It was still extremely difficult for a U-boat to navigate without surfacing. But U-boats operating in the dangerous waters south of
