Marching Orders: The Untold Story of How the American Breaking of the Japanese Secret Codes Led to the Defeat of Nazi Germany and Japan

by Bruce Lee

As a result, as Henry Clausen explained to me, just before congressional Pearl Harbor hearings open in November 1945, the Republicans on the committee blithely release the news that before and during the war the British and the Americans had broken both the German and Japanese codes. This breach of national security is done after Marshall begs the committee to keep the secret. The committee refuses, publishing Marshall’s correspondence with Dewey. Thus, our Congress gives our former enemies the first knowledge that their codes had been broken, to say nothing about breaching America’s diplomatic confidence with the British. The latter are livid with rage about the disclosures. And rightly so.29
