Zigmond Adler was three years old when Germany occupied Belgium in May 1940. Zigmond, whose mother was deceased, went to live with his aunt and uncle after the Germans deported his father. With the help of Catholic friends, Zigmond and his relatives hid under false identities. After two years, they were caught by the Gestapo. Zigmond was sent to the Mechelen transit camp, and then to Auschwitz, where he was gassed. He was seven years old.
These maps add geographic context to Zigmond's experiences.

This map shows the Auschwitz camp complex in the summer of 1944.
The SS established Auschwitz in spring 1940 as a concentration camp for Polish political prisoners. It was located in German-occupied Poland on the outskirts of the town of Oświęcim. Over the next several years, the camp was expanded and transformed into a sprawling camp complex. In March 1942, the SS began operating a killing center at Auschwitz where they murdered Jewish people from all over Europe.
By 1944, the Auschwitz camp complex included multiple camps that served different purposes. The largest of the Auschwitz camps included the Auschwitz main camp (Auschwitz I); Auschwitz-Birkenau (Auschwitz II), which included the killing center; and Auschwitz-Monowitz (Auschwitz III). There were also numerous smaller subcamps.
At Auschwitz, the Germans killed about 1.1 million people, including approximately 1,000,000 Jews, 70,000 Poles, 21,000 Roma and Sinti, and 15,000 Soviet prisoners of war.
