Bitton-Jackson lived in Samorja, Hungary, when the Germans invaded in 1944. The segregation of Jews began at that time, and they were prohibited from entering theaters, restaurants, and grocery stores. Two months into the German occupation, she was, along with all the Jews in that area, moved to a ghetto that consisted of a synagogue and roughly 20 surrounding houses. Partway through their stay there, all men between the ages of 18 and 45, her father included, were sent to a forced labor camp in Komárom, some fifty miles from the ghetto. Two weeks after her father was taken, Bitton-Jackson, her aunt, mother, and brother were removed from the ghetto and taken, over a journey of four days, to Auschwitz, the largest concentration camp in Poland. She and her mother stayed there for ten days. In June 1944, Bitton-Jackson and her mother were transferred, along with 500 other women, to Camp Plaszow, the most notorious forced labor camp in Poland. There, their work consisted of leveling off a hilltop in preparation for construction. If they did not work, or work properly, or violated any rule, they would be beaten by their Kapo, or his assistants. After two months stay at Plaszow, they returned to Auschwitz.
In August 1944, Bitton-Jackson and her mother are taken from Auschwitz to a factory in Augsburg. In Augsburg, she was put to work in an assembly line in the factory, where they produced a
