In July 1941, there were approximately 26,000 to 28,000 Jewish forced laborers in Berlin. Many of them were forced to work in war-related industries along with non-Jewish foreign civilian workers and prisoners of war (POWs). There were approximately 3 million foreigners in Germany in 1941, and most of them worked in the agricultural sector. By 1943, 5.7 million civilian workers and 2 million POWs from several nations were working for the German Reich. In February 1943, Hitler ordered the roundup of all Jewish laborers in Germany and most of them were deported during the following weeks and months. Until that time, Jewish forced laborers in war-related industries had been exempt from deportation.
