On 1 April 1924, Hitler was sentenced to five years' imprisonment at Landsberg Prison. There, he received friendly treatment from the guards, and was allowed mail from supporters and regular visits by party comrades. Pardoned by the Bavarian Supreme Court, he was released from jail on 20 December 1924, against the state prosecutor's objections. Including time on remand, Hitler served just over one year in prison.
On 2 January 1951, Konrad Adenauer met with the American High Commissioner, John J. McCloy, to argue that executing the Landsberg prisoners would ruin forever any effort at having the Federal Republic play its role in the Cold War.
