Book excerpt: During World War II at least 13.5 million people were employed as forced labourers in Germany and across the territories occupied by the German Reich. Most came from Russia, Ukraine, Belarus, Moldavia, the Baltic countries, France, Poland and Italy. Among them were 8.4 million civilians working for private companies and public agencies in industry, administration and agriculture. In addition, there were 4.6 million prisoners of war and 1.7 million concentration camp prisoners who were either subjected to forced labour in concentration or similar camps or were ‘rented out’ or sold by the SS. While there are numerous publications on forced labour in National Socialist Germany during World War II, this publication combines a historical account of events with the biographies and memories of former forced labourers from twenty-seven countries, offering a comparative international perspective.
