Wilhelmstraßen-Prozess
After the war, Schellenberg was arrested by British military police and eventually stood trial in Nuremberg. To spare himself from a long prison sentence, during the postwar Nuremberg Trials, Schellenberg testified against the SS organisation and the Nazi leaders in its fold. During the Ministries Trial, he wrote his memoirs, titled "The Labyrinth". Historian Robert Gerwarth describes certain content of Schellenberg's memoirs as "questionable." On 4 November 1949, he was sentenced to six years in prison for his role in the murder of Soviet POWs who were utilized as agents in Operation Zeppelin. He was released from prison after two years on the grounds of ill-health, due to a worsening liver condition, and moved to Switzerland, before settling in Verbania-Pallanza, Italy. In 1952, he died in Turin, Italy.
