In 1941, after Nazi Germany invaded the Soviet Union, Torgler worked on anti-Bolshevik propaganda at the behest of Joseph Goebbels. Later that year, Torgler worked in Czechoslovakia on the staff of Reinhard Heydrich. In 1944, after the 20 July Plot against Adolf Hitler, an arrest warrant was issued for Torgler, who was still working for the propaganda ministry. Torgler, by his own account, was spared from being arrested only because his boss vouched for his loyalty. Then, Torgler worked in Poland until he was transferred by the Nazis to the town of Bückeburg, where he worked in its administration. After World War II, he was denazified and landed a job with the administration of Bückeburg, with help of the US Army. Despite the hard times, Torgler managed to keep himself in a well-paid position. Torgler angrily dismissed charges that he had willingly co-operated with the Nazis. He tried to join the communists but was rejected. In 1949, he became a member of the Social Democratic Party and in 1950, he moved to Bückeburg, where he drifted into obscurity. He died in Hanover in 1963. His son, Kurt Torgler (1913–1943), was a witness on behalf of his father at the 1933 countertrial in London that was organised by the German Communist Party on the Reichstag fire. In 1935, he went to the Soviet Union. There, he was arrested by the NKVD in 1937 and sent to a labour camp. After the Hitler-Stalin Pact, he was, in 1940, handed over to the German government. He became a translator in the army and died on the Eastern Front.
