Soviet civilian populations in the occupied areas were heavily persecuted.[438] Villages throughout the Soviet Union were destroyed by German troops.[439] Germans rounded up civilians for forced labor in Germany and caused famine by taking foodstuffs.[440] In Belarus, Germany imposed a regime that deported some 380,000 people for slave labor and killed hundreds of thousands of civilians. Over 600 villages had their entire populations killed, and at least 5,295 Belarusian settlements were destroyed by the Germans. According to Timothy Snyder, of "the nine million people who were in the territory of Soviet Belarus in 1941, some 1.6 million were killed by the Germans in actions away from battlefields, including about 700,000 prisoners of war, 500,000 Jews, and 320,000 people counted as partisans (the vast majority of whom were unarmed civilians)".[441] The United States Holocaust Memorial Museum has estimated that 3.3 million of 5.7 million Soviet POWs died in German custody.[442] The death rates decreased as the POWs were needed to help the German war effort; by 1943, half a million had been deployed as slave labor.[409]
In his 1965 essay "Command and Compliance", which originated in his work as an expert witness for the prosecution at the Frankfurt Auschwitz Trials, the German historian Hans Buchheim wrote there was no coercion to murder Jews and others, and all who committed such actions did so out of free will. Buchheim wrote that chances to avoid executing criminal orders "were both more numerous and more real than those concerned are generally prepared to admit",[468] and that he found no evidence that SS men who refused to carry out criminal orders were sent to concentration camps or executed.[469] Moreover, SS rules prohibited acts of gratuitous sadism, as Himmler wished for his men to remain "decent"; acts of sadism were carried out on the initiative of those who were either especially cruel or wished to prove themselves ardent National Socialists.[468] Finally, he argued that those of a non-criminal bent who committed crimes did so because they wished to conform to the values of the group they had joined and were afraid of being branded "weak" by their colleagues if they refused.[470]
After the outbreak of World War II, the Wehrmacht set up a camp for Belgian and French prisoners of war in huts at the edge of the Bergen Military Training Area. The camp was significantly expanded in the spring of 1941. Following the German invasion of the Soviet Union, over 21,000 Soviet POWs were deported to the camp until the autumn of 1941. Between July 1941 and April 1942, 14,000 Soviet POWs died there of starvation, disease and exposure. 
The site is open to the public and includes monuments to the dead, including a successor to the wooden cross of 1945, some individual memorial stones and a "House of Silence" for reflection. In addition to the Jewish, Polish and Dutch national memorials, a memorial to eight Turkish citizens who were killed at Belsen was dedicated in December 2012.[36]
Policies differed widely among Germany’s Balkan allies. In Romania it was primarily the Romanians themselves who slaughtered the country’s Jews. Toward the end of the war, however, when the defeat of Germany was all but certain, the Romanian government found more value in living Jews who could be held for ransom or used as leverage with the West. Bulgaria deported Jews from neighbouring Thrace and Macedonia, which it occupied, but government leaders faced stiff opposition to the deportation of native Bulgarian Jews, who were regarded as fellow citizens.
Then as a last straw the Allies bombed the electric plant that pumped our water. Loads of food were unable to reach the camp because of the Allied fighters. Then things really got out of hand. During the last six weeks I have been helpless. I did not even have sufficient staff to bury the dead, let alone segregate the sick ... I tried to get medicines and food for the prisoners and I failed. I was swamped. I may have been hated, but I was doing my duty.
Behind the furnace was the execution chamber, a windowless cell twenty feet square with gas nozzles every few feet across the ceiling. Outside, in addition to the huge mound of charred bone fragments, were the carefully sorted and stacked clothes of the victims - which obviously numbered in the thousands. Although I stood there looking at it, I couldn't believe it. The realness of the whole mess is just gradually dawning on me, and I doubt if it will ever on you.
Between April and June of 1940, Germany invaded Norway, Denmark, the Netherlands, Belgium, and Luxembourg consolidating power across neutral Western Europe. On June 22, 1940, France signed an armistice with Germany, which divided France between the German-occupied territory in the north and the Vichy regime in the south. Although officially neutral, the French state during this time was generally pro-Nazi and cooperated with Germany’s racial policies.
After invading Poland, the Germans established ghettos in the incorporated territories and General Government to confine Jews.[143] The ghettos were formed and closed off from the outside world at different times and for different reasons.[196][197] For example, the Łódź ghetto was closed in April 1940,[143] to force the Jews inside to give up money and valuables;[198] the Warsaw ghetto was closed for health considerations (for the people outside, not inside, the ghetto),[199] but this did not happen until November 1940;[143] and the Kraków ghetto was not established until March 1941.[200] The Warsaw Ghetto contained 380,000 people[143] and was the largest ghetto in Poland; the Łódź Ghetto was the second largest,[201] holding between 160,000[202] to 223,000.[203] Because of the long drawn-out process of establishing ghettos, it is unlikely that they were originally considered part of a systematic attempt to eliminate Jews completely.[204]
That February 28 decree had been used by the 50,000 brown-shirted SA storm troopers and black-coated SS men sworn in as auxiliary police to justify mass arrests of political opponents during Hitler's seizure of power. There were so many people in custody in the spring of 1933 that Germany's conventional prisons were quickly swamped. As a result, 'wild' prison camps sprang up like mushrooms.
The camp of huts near Fallingbostel became known as Stalag XI-B and was to become one of the Wehrmacht's largest POW camps, holding up to 95,000 prisoners from various countries.[6] In June 1940, Belgian and French POWs were housed in the former Bergen-Belsen construction workers' camp. This installation was significantly expanded from June 1941, once Germany prepared to invade the Soviet Union, becoming an independent camp known as Stalag XI-C (311). It was intended to hold up to 20,000 Soviet POWs and was one of three such camps in the area. The others were at Oerbke (Stalag XI-D (321)) and Wietzendorf (Stalag X-D (310)). By the end of March 1942, some 41,000 Soviet POWs had died in these three camps of starvation, exhaustion, and disease. By the end of the war, the total number of dead had increased to 50,000.[6] When the POW camp in Bergen ceased operation in early 1945, as the Wehrmacht handed it over to the SS, the cemetery contained over 19,500 dead Soviet prisoners.
