All this and much more Mr. Le Drieullenac told the court. The effect on his hearers was to blanket to a great extent the impression they had received from the film which had shown the prisoners in the dock carting dead bodies like Smithfield porters carrying sides of mutton – bodies which could not have been heavier – to the burial pit, and then, with one man taking the legs and others the hands, throwing them into the pit. S.S. women also were engaged in this work, but probably the most horrible shot of all showed a bulldozer pushing piles of bodies towards the pit, the driver hanging on to the wheel with one hand and holding a handkerchief to his nose with the other.
Entering conquered Soviet territories alongside the Wehrmacht (the German armed forces) were 3,000 men of the Einsatzgruppen (“Deployment Groups”), special mobile killing units. Their task was to murder Jews, Soviet commissars, and Roma in the areas conquered by the army. Alone or with the help of local police, native anti-Semitic populations, and accompanying Axis troops, the Einsatzgruppen would enter a town, round up their victims, herd them to the outskirts of the town, and shoot them. They killed Jews in family units. Just outside Kiev, Ukraine, in the ravine of Babi Yar, an Einsatzgruppe killed 33,771 Jews on September 28–29, 1941. In the Rumbula Forest outside the ghetto in Riga, Latvia, 25,000–28,000 Jews were shot on November 30 and December 8–9. Beginning in the summer of 1941, Einsatzgruppen murdered more than 70,000 Jews at Ponary, outside Vilna (now Vilnius) in Lithuania. They slaughtered 9,000 Jews, half of them children, at the Ninth Fort, adjacent to Kovno (now Kaunas), Lithuania, on October 28.
In the first half of 1944, the “star camp” also took in small transports of Jews from various other countries. These included 200 Jews from Tunisia, Tripoli, and Benghazi , who until then had been held in the Fossoli di Carpi camp in Italy: 200 Jewish women from the Drancy transit camp in France, whose husbands were French prisoners-of –war, being held by the Germans, and several hundred Jews from Yugoslavia and Albania.
Hitler quickly moved to cement his power by suspending many civil liberties and allowing imprisonment without trial. By March, the first Nazi concentration camp was established at Dachau, not to imprison Jews but to hold political dissidents. Further laws targeted Jews, restricting the jobs they could hold and revoking their German citizenship. Anti-Semitic sentiment increased as the Jewish population was blamed for many of Germany's recent and historical problems.
A further regulation stated that a prisoner would be shot or hanged for refusing to obey any order from an SS man. Those who were gunned-down had their deaths listed as "shot while attempting to escape." The only notification the victim's family ever got was an urn filled with ashes delivered to their front door. The ashes were usually not even from the dead man himself, but had been scooped up from whatever was lying around in the crematorium room.
The workers who constructed the original buildings were housed in camps near Fallingbostel and Bergen, the latter being the so-called Bergen-Belsen Army Construction Camp. Once the military complex was completed in 1938/39, the workers' camp fell into disuse. However, after the German invasion of Poland in September 1939, the Wehrmacht began using the huts as a prisoner of war (POW) camp.
