After the Allied bombing of Hamburg in July 1943, operations essential to the war effort were relocated to the surrounding area. This was the reason why the Philips-Valvo valve plant in Hamburg-Lokstedt also outsourced parts of its production to an empty section of a leather factory in Horneburg. Between October 1944 and February 1945, approximately 200 Hungarian Jews and 50 Dutch women were forced to manufacture valves for radios, telecommunications equipment as well as light bulbs and other products for submarines. Some women - especially the Dutch - were also deployed to work at the port of Horneburg. The Jewish women from Hungary had been taken to Horneburg via Auschwitz-Birkenau, while the Dutch women came via Ravensbrück concentration camp. In mid-February 1945, the SS transported the women to the Porta Westfalica satellite camp for women. The commander of the Horneburg satellite camp for women in 1944/45 was SS-Unterscharführer Peter Klaus Friedrich Hansen.

On 24 February 1945, the camp received another transport of prisoners: 300 Jewish women from Hungary who had previously been imprisoned in the Weißwasser camp (a satellite camp of Groß-Rosen concentration camp) and in Auschwitz. In Horneburg, these women were forced to manufacture valves and light bulbs for Philips-Valvo, just as they had done in Weißwasser. On 8 April, the women were transported by rail to Bergen-Belsen, where they arrived on 11 April.

After long public debate, a memorial stone with a plaque was finally erected on 22 October 1997 at the site of the former satellite camp. The memorial was financed by private donations and initiated by private individuals and the Free Democratic Party of Horneburg.
