In November 1923 Hitler had led an attempted coup against the Weimar Government by trying to seize power in the Bavarian city of Munich. The putsch failed and Hitler was found guilty of treason in the subsequent trial. Sentenced to five years imprisonment, he was sent to the Festungshaft prison in the Bavarian town of Landsberg am Lech.
Hitler’s ‘fortress confinement’ provided him with a reasonably comfortable cell in comparison to conventional facilities, and meant that he was able to receive mail and have regular visitors. The discovery in 2010 of more than 500 documents relating the Hitler’s imprisonment show that more than 30 people were able to visit him on his birthday on 20 April 1924, just 19 days into his sentence.
Imprisonment provided Hitler with the opportunity to dictate his autobiography, Mein Kampf, to his deputy Rudolf Hess. It was in this book that Hitler laid out his blueprint for the future of Germany. Although it gained only modest success when it was first published, Winston Churchill later claimed that if world leaders had read it they could have better anticipated the scale of Nazi domestic and foreign policy.
In a memorandum dated 18 September 1924, the Landsberg warden Otto Leybold described Hitler as “sensible, modest, humble and polite to everyone – especially the officers of the facility”. He was released on 20 December 1924 after serving on nine months of his five-year sentence and soon set about rebuilding the Nazi Party which had been banned in Bavaria as a result of the Beer Hall Putsch. The ban was lifted less than two months after Hitler’s release.
