Shortly after their rise to power, the Nazis established specific Arbeitslager (labour camps) which housed Ostarbeiter (eastern workers), Fremdarbeiter (foreign workers) and other forced labourers who were rounded up and brought in from the east. These were distinct from the SS-run concentration camps. The use of forced labour grew significantly in 1937 due to rearmament requirements and again after the outbreak of warThe invasion of the Soviet Union in June 1941 further heightened demands for labour and the availability of new workers in areas under Nazi occupation. Vast numbers were deported to forced labour camps, where they worked either producing war materials or on construction projects. As in the Nazis’ view, inmates were slaves pure and simple and replaceable with others, there was a complete disregard for the health of prisoners. Required to work long hours with little or no time for rest or breaks they were subject to insufficiencies of food, equipment, medicine and clothing. As a result of these conditions and brutal treatment, death rates were shockingly high. By 1945, more than fourteen million people had been exploited in the network of hundreds of forced labour camps that stretched across Nazi-occupied Europe. In true Images of War series style, this superbly illustrated book graphically describes the growth of the slave camp system and the conditions inflicted on the luckless labour force.
