Estimates of Jewish participation in partisan units throughout Europe range from 20,000 to 100,000.[323] In the occupied Polish and Soviet territories, thousands of Jews fled into the swamps or forests and joined the partisans,[324] although the partisan movements did not always welcome them.[325] An estimated 20,000 to 30,000 joined the Soviet partisan movement.[326] One of the famous Jewish groups was the Bielski partisans in Belarus, led by the Bielski brothers.[324] Jews also joined Polish forces, including the Home Army. According to Timothy Snyder, "more Jews fought in the Warsaw Uprising of August 1944 than in the Warsaw Ghetto Uprising of April 1943".[327][r]
Advocacy organizations worldwide called for British Royal Air Forces to bomb concentration camps particularly at Auschwitz. Although the plan was adopted by British Prime Minister Winston Churchill poor information-sharing between parts of the British government led the order to be ignored and the plan dropped. Such calculations were hardly the low point of Allied Responses. One story has that, low on supplies, the Nazis offered the British a million Jews in exchange for 10,000 trucks, which one British diplomat promptly refused saying, “What would I do with one million Jews? Where would I put them?”
Bergen-Belsen was first established in 1940 as a prisoner of war camp. From 1943, Jewish civilians with foreign passports were held as ‘leverage’ in possible exchanges for Germans interned in Allied countries or for money. It later became a concentration camp and was used as a collection centre for survivors of the death marches. The camp became exceptionally overcrowded and, as a result of the Germans’ neglect, conditions were allowed to deteriorate further in the last months of the war, causing many more deaths.
Smith put the total number of survivors at around 32,600, but said that between 100 and 200 a day were still dying after the camp was liberated. He mentioned that the American Army tried to keep the freed prisoners in the camp to prevent the typhus epidemic from spreading throughout the country. Typhus is spread by lice, and the clothing was being deloused in an attempt to stop the epidemic.
The total number of deaths in the first five months of 1945 was almost half the total deaths in the 12-year history of the camp. The death rate in the other Nazi concentration camps also rose dramatically in the last months of the war, as the typhus epidemic spread throughout Germany. American POWs in German camps were saved from the epidemic by booster shots of typhus vaccine sent to them from America by the International Red Cross. The Germans were conducting experiments at the Buchenwald camp in an effort to develop a vaccine for typhus, but had not been successful. After the war, the doctors who had attempted to develop a typhus vaccine at Buchenwald were put on trial as war criminals at Nuremberg in the Doctor's Trial conducted by Americans.

Following the invasion of Poland, German occupation policy especially targeted the Jews but also brutalized non-Jewish Poles. In pursuit of lebensraum, Germany sought systematically to destroy Polish society and nationhood. The Nazis killed Polish priests and politicians, decimated the Polish leadership, and kidnapped the children of the Polish elite, who were raised as “voluntary Aryans” by their new German “parents.” Many Poles were also forced to perform hard labour on survival diets, were deprived of property and uprooted, and were interned in concentration camps.
Soon after his marriage, Schindler quit working for his father and took a series of jobs, including a position at Moravian Electrotechnic and the management of a driving school. After an 18-month stint in the Czech army, where he rose to the rank of Lance-Corporal in the Tenth Infantry Regiment of the 31st Army, Schindler returned to Moravian Electrotechnic, which went bankrupt shortly afterwards. His father's farm machinery business closed around the same time, leaving Schindler unemployed for a year. He took a job with Jarslav Simek Bank of Prague in 1931, where he worked until 1938.[4]
Mass grave at Belsen camp, shortly after its liberation by British troops. Photographs such as this are widely reproduced as proof of a German policy of extermination. Contrary to Allied propaganda claims of the time, and Holocaust allegations in recent decades, though, these unfortunate prisoners were victims of typhus and starvation that were indirect consequences of the war – not of any deliberate policy. At least 14,000 Jews died in the camp following the British takeover.

Marc Coyle (?) reached the camp two days before I did and was a guard so as soon as I got there I looked him up and he took me to the crematory. Dead SS troops were scattered around the grounds, but when we reached the furnace house we came upon a huge stack of corpses piled up like kindling, all nude so that their clothes wouldn't be wasted by the burning. There were furnaces for burning six bodies at once and on each side of them was a room twenty feet square crammed to the ceiling with more bodies - one big stinking rotten mess. Their faces purple, their eyes popping, and with a ludicrous (?) grin on each one. They were nothing but bones & skin. Coyle had assisted at ten autopsies the day before (wearing a gas mask) on ten bodies selected at random. Eight of them had advanced T.B., all had Typhus and extreme malnutrition symptoms. There were both women and children in the stack in addition to the men.
Many of the prisoners at Bergen Belsen arrived there on death marches from other concentration camps. During Summer 1944, as the British and American Armies advanced in their fight against Germany from the West and the Soviet army advanced in its fight against Germany from the East, the Nazis began liquidating concentration camps, sending prisoners on death marches. They forced prisoners of concentration camps to march over long distances, under unbearable conditions. Prisoners were abused, and sometimes killed, by the guards that accompanied them. 
By January 1946, 18,000 members of the SS were being confined at the camp along with an additional 12,000 persons, including deserters from the Russian army. The occupants of one barracks rioted as 271 of the Russian deserters were to be loaded onto trains that would return them to Russian-controlled lands, as agreed at the Yalta Conference. Ten of the soldiers, who had been captured in German Army uniforms, committed suicide during the riot. Twenty-one others attempted suicide, apparently with razor blades. Many had "cracked heads" inflicted by 500 American and Polish guards, in the attempt to bring the situation under control. Inmates barricaded themselves inside and set fire to the building, tore off their clothing, and linked arms to resist being removed from the building. Some begged American soldiers to shoot them. Tear gas was used by the soldiers before rushing the building.[103]

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]

In 1935 the Wehrmacht began to build a large military complex close to the village of Belsen, a part of the town of Bergen, in what was then the Province of Hanover.[1] This became the largest military training area in Germany of the time and was used for armoured vehicle training.[1] The barracks were finished in 1937. The camp has been in continuous operation since then and is today known as Bergen-Hohne Training Area. It is used by the NATO armed forces.
