Geppersdorf labour camp

The German military took over Będzin on the first day of the invasion, burned the Grand Synagogue down within a week, and began massive resettlement actions. On 28 October 1940 Gertner was ordered to report to the train station in nearby Sosnowiec, where she was taken to a Nazi labor camp in Geppersdorf (now Rzedziwojowice), a construction site where hundreds of Jewish men were used as forced laborers on the Reichsautobahn section (now Berlinka) and where women worked in the kitchen and laundry. Gertner, who was fluent in German, was assigned to the camp office, where she met prisoner Bernhard Holtz whom she would marry in the Będzin Ghetto in the following year.^[2]

Geppersdorf was part of Organisation Schmelt, a network of 177 labor camps under the administration of Albrecht Schmelt, a World War I veteran who joined the Nazis in 1930 and rose quickly to the post of SS Oberführer. Because of his familiarity with the local political and social conditions in the annexed region of western Poland, Schmelt was hand-picked by SS head Heinrich Himmler to be "Special Representative of the Reichsführer SS for the Employment of Foreign Labor in Upper Silesia." After his official appointment in October 1940, Schmelt set up headquarters in Sosnowiec and created a labor camp system that would become known as Organisation Schmelt.

Schmelt built a highly lucrative slave trade. Over 50,000 Jews from western Poland were forced to work for German businesses, primarily in construction, munitions, and textile manufacturing. The businesses paid Schmelt, who shared a fraction of the money with Moses Merin, the Jewish governor of the region. Almost none of it went to the Jewish laborers. Conditions varied, but were much better than in the large concentration camps: for example, mail and packages could be received in some of the Schmelt camps until 1943, when the Schmelt labor camps became part of Auschwitz and Gross-Rosen. (Oskar Schindler's camp was originally under Organization Schmelt.)

In 1941, Gertner was allowed to return home. She was employed in various local workshops and offices run by Moses Merin. She and Bernhard Holtz were married in the Sosnowiec Ghetto of Środula on 22 May 1943. They lived in the Będzin Ghetto neighbourhood of Kamionka until sometime after 16 July 1943 (the date of Gertner's last known letter) and were probably deported to Auschwitz with the remaining Jews of Sosnowiec and Będzin in early August 1943.

At Auschwitz

At Auschwitz, Gertner worked in the warehouses at first, sorting the possessions of Jews who had been gassed. She became friendly with Roza Robota, who was active in the underground resistance. Gertner was then assigned to the office of the munitions factory, where she and Roza became part of a conspiracy to smuggle gunpowder to the Sonderkommando, who were building bombs and planning an escape. Gertner recruited other women to join the conspiracy, and passed the stolen gunpowder to Roza.

On 7 October 1944 the Sonderkommando blew up Crematorium IV, but the revolt was quickly quelled by the armed SS guards. A lengthy investigation led the Nazis back to Gertner and Roza, and then to Estusia Wajcblum and Regina Safirsztajn, who were also implicated in the conspiracy. They were interrogated and tortured for weeks. On 5 January 1945 the four women were publicly hanged in Auschwitz.^[3] Other sources give 6 January as the date of the execution.^[4][5] This was the last public hanging at Auschwitz:^[4] two weeks later, the camp was evacuated.
