Answer: The years 1939–1942 saw a marked expansion in the concentration camp system. In 1938, SS authorities had begun to exploit the labor of concentration camp prisoners for economic profit. In September 1939, the war provided a convenient excuse to ban releases from the camps, thus providing the SS with a readily available labor force.SS authorities established new camps in the vicinity of factories (for example, the brickworks at Neuengamme, 1940) or sites for the extraction of raw materials (such as the stone quarry at Mauthausen, 1938). The goods extracted or produced by prisoner labor were sold to the German Reich through SS-owned firms such as the German Earth and Stone Works.
