There were 20 Concentration and Death Camps built from the slave labor of Jewish prisoners. Not seen on this map are the additional 90+ labor camps that Jews were sent to work for the Nazis. They were building facilities, roads, ditches or tunnels and they were worked to death in miserable conditions. Emanuel’s younger brother Mordchai and father Eliezer were sent to Melk a sub-camp of Mauthausen in Austria where they either died from the inhumane working or living conditions or when the allies were bombing the Nazis they may have been caught in the cross-fire.
