It has long been accepted that there were no German spies at large in Britain during the Second World War, but captured German documents and newly released MI5 files reveal that the famed double-cross system was, in fact, a German triple-cross and that the Soviets had also penetrated the Security Service. When British Intelligence discovered this information, it secretly turned the situation to its advantage during the Battle of Britain. The newly released documents also show that the German Secret Intelligence chief contrived to keep Britain in the war and may have had a direct hand in helping to lure the Japanese into attacking Pearl Harbor. These revelations and others like them make Fighting to Lose the most fascinating new book about the Second World War to be published for many years. Based mainly on primary source research, Bryden reveals that German Intelligence knew about Britain's radar network before the Battle of Britain and presents new evidence that President Roosevelt deliberately left the U.S. Pacific Fleet open to Japanese attack in order to get America into the war.
