The Emperor's Codes: The Breaking of Japan's Secret Ciphers - Tapa blanda

In this gripping, previously untold story from World War II, Michael Smith examines how a group of eccentric codebreakers cracked Japan's secret codes and turned the tide of the war in the Pacific. Drawing upon recently declassified British files, privileged access to Australian secret official histories, and interviews with many of the men involved, The Emperor's Codes takes the reader step-by-step through the codebreaking process, explaining exactly how the codebreakers went about their daunting task-made even more difficult by the vast linguistic differences between Japanese and English. It details the grueling work and almost unfathomable dedication demonstrated by these relatively unsung heroes, without whose extraordinary exploits the outcome of World War II might have been very different.

Michael Smith served for nine years in the British Army's Intelligence Corps as a latter-day codebreaker before going to work for the BBC Monitoring Service. He has written for a number of newspapers, including the Financial Times, the Sunday Times, and most recently the Daily Telegraph, where he is Defense Correspondent.
