The Emperor's Codes

Many of these revelations have been made possible only through using recently declassified British files, through privileged access to Australian secret official histories, and interviews with an unprecedented number of British, American and Australian codebreakers." "Where previous books on the subject have emphasized the role played by the Americans, The Emperor's Codes is the first full account of the critical role played by British and Australian codebreakers. Using the memories of those at the forefront of this battle, Michael Smith reveals a gripping and previously untold story from the Second World War."--BOOK JACKET.
