Hidden behind the code name "Goldfish" was nothing less then the relocated Daimler-Benz engine plant - from Berlin Ludwigsfelde/Brandenburg to the Neckar. In 1944, the mechanical assembly of the largest German airplane engine factory was rebuilt almost completely underground in the gypsum mine in Obrigheim.
Concentration camp prisoners were used for the construction work. Free workers, predominantly foreign workers from many different countries were used for the production of the engines. In total, "Goldfish" engaged approximately 10,000 people.
After the occupation by the American troops, the gypsum mine was returned. The mine is still used today to extract gypsum for the production of concrete and cement.
Beginning in the middle of March 1944, the concentration camp prisoners worked day and night. They worked in two shifts under miserable conditions - being beaten, poorly nourished and not properly clothed. They had to set up the construction site, free the corridors inside the mine from mud and boulders, and pour concrete over an area of 50,000 square meters. Outside the gallery, they were required to set up more buildings and facilities.
On June 26, 1944 the first machines from Genshagen arrived by train. At the same time, the workers arrived. Overall, almost 5,000 "Loyal Workers" (free workers and "foreign workers" - including women) poured into the region. They lived mostly in barracks, and were treated a little better than the concentration camp prisoners. All in all, "Goldfish" "employed" 10,000 people.
In October 1944, the first engines were delivered. The monthly quota of 1,000 units was never reached. Problems receiving new supplies, and bomb attacks caused the production to come to a halt in February 1945. Beginning in the middle of March, the workers were "sent off".
