The Rise and Fall of the Third Reich
No other powerful empire ever bequeathed such mountains of evidence about its birth and destruction as the Third Reich. When the bitter war was over, and before the Nazis could destroy their files, the Allied demand for unconditional surrender produced an almost hour-by-hour record of the nightmare empire built by Adolph Hitler. This record included the testimony of Nazi leaders and of concentration camp inmates, the diaries of officials, transcripts of secret conferences, army orders, private letters—all the vast paperwork behind Hitler's drive to conquer the world.
