The company actively sought out forced labor from the concentration camp system. One VW plant engineer traveled to Auschwitz and selected 300 skilled metalworkers from the massive transports of Hungarian Jews in 1944. In addition, 650 Jewish women were transferred to assemble military munitions. The official relationship between the Nazi concentration camps and Volkswagen was cemented when the Fallersleben facility officially became a subcamp of the Neuengamme concentration camp. Overall, the Volkswagen plant contained four concentration camps and eight forced-labor camps.
