Reder was extradited to Italy in May 1948 to stand trial for war crimes. He was tried by an Italian military court in Bologna for ordering the destruction of town of
Marzabotto and other villages near Bologna in August and September of 1944 during so-called anti-partisan sweeps, and for ordering the execution of 2,700 Italian civilians in
Tuscany and
Emilia during the same period. In October 1951, he was sentenced to life imprisonment at a fortress prison in
Gaeta, on the
Tyrrhenian Sea coast between Naples and Rome. The citizens of Marzabotto and survivors of the massacre voted 237 to 1 against freeing Reder. Local officials had stated that as many as 1,830 civilians died in massacres in and around Marzabotto. Years later, a group of SS men whom Reder had commanded in 1944 were tried and convicted for their role in the
Sant'Anna di Stazzema massacre. Their convictions and sentencing were conducted in absentia. Reder was paroled in January 1985, after which he returned to Austria. He died in 1991. == References ==
