After President Paul von Hindenburg was asked by the Nazi-controlled German Cabinet that night to use his emergency powers under Article 48 of the German Constitution to suspend certain civil rights, 2,000 leading Communists throughout Germany were imprisoned without formal charges being brought against them and without a trial. They were held in abandoned buildings such as the camp in an old brewery in Oranienburg; this camp was rebuilt in 1936 as the Sachsenhausen concentration camp. On March 21, 1933, Communists in the town of Dachau were imprisoned in the building which now houses the New Gallery for modern art. Other Communists were sent to prisons such as the federal prison at Landsberg am Lech, where Hitler himself had formerly been a prisoner after his failed Putsch in 1923.
That June, Theodor Eicke (1892-1943) replaced Wäckerle as Dachau commandant. Eicke immediately released a set of regulations for the camp’s daily operation. Prisoners deemed guilty of rule breaking were to be brutally beaten. Those who plotted to escape or espoused political views were to be executed on the spot. Prisoners would not be allowed to defend themselves or protest this treatment. Eicke’s regulations served as a blueprint for the operation of all concentration camps in Nazi Germany.
Those who could prove their intention to leave Germany were released, and indeed most of them were released within a few months of their arrest. Non-Jews were also arrested for helping Jews, in Berlin on 23 October 1941 a German Catholic priest, Bernhard Lichtenberg, who had been a military chaplain in the First World War, was arrested for his protests against the deportations to the East.
Between the years 1933 and 1945, more than 3.5 million Germans were imprisoned in such concentration camps or prison for political reasons. Approximately 77,000 Germans were killed for one or another form of resistance by Special Courts, courts-martial, and the civil justice system. Many of these Germans had served in government, the military, or in civil positions, which were considered to enable them to engage in subversion and conspiracy against the Nazis.
The gates of the camp had been locked again, and the liberators of the first hour, on their way again, were already far off, toward Munich, toward the south, pursuing their war. Guards had been placed on the other side of the barbed wire. No one was allowed out any more, Already, at the end of this first day, the Americans wondered what they would do with his rabble of lepers.
The twin goals of racial purity and spatial expansion were the core of Hitler’s worldview, and from 1933 onward they would combine to form the driving force behind his foreign and domestic policy. At first, the Nazis reserved their harshest persecution for political opponents such as Communists or Social Democrats. The first official concentration camp opened at Dachau (near Munich) in March 1933, and many of the first prisoners sent there were Communists.
Soviet civilian populations in the occupied areas were heavily persecuted. Villages throughout the Soviet Union were destroyed by German troops. Germans rounded up civilians for forced labor in Germany and caused famine by taking foodstuffs. 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)". The United States Holocaust Memorial Museum has estimated that 3.3 million of 5.7 million Soviet POWs died in German custody. 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.
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. 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. 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.
