The camps were established to provide labor for an underground installation for the production of the Messerschmitt Me 262, a jet fighter designed to challenge Allied air superiority over Germany.
To facilitate these immense projects, it set up hundreds of satellite camps close to proposed industrial sites in 1944 and 1945.
As at the Kaufering camps, the SS guards carried out "selections" at the Mühldorf complex in the fall of 1944, deporting hundreds of sick and disabled inmates to the gas chambers at Auschwitz.
It is estimated that more than half of the prisoners held there perished following their deportation to the Auschwitz-Birkenau killing center or died on site from overwork, abuse, shootings, and disease.
Prisoners frequently worked 10- to 12-hour days hauling heavy bags of cement and carrying out other arduous construction tasks.
