The first prisoners were brought to Hartheim on 14th August 1941, followed – after a brief interruption in late August – by more transports during December 1941 and February 1942. For 1943 there are no documents to prove that prisoners were gassed at Hartheim during this year. When the number of sick prisoners once again began to increase, the death transports resumed on 11th April 1944. In total, 2.000 prisoners from Gusen were killed by gas at Hartheim Castle.
