After some time off to recover in Zwittau, Schindler was promoted to second in command of his Abwehr unit and relocated with his wife to Ostrava, on the Czech-Polish border, in January 1939. He was involved in espionage in the months leading up to Hitler's seizure of the remainder of Czechoslovakia in March. Emilie helped him with paperwork, processing and hiding secret documents in their apartment for the Abwehr office. As Schindler frequently travelled to Poland on business, he and his 25 agents were in a position to collect information about Polish military activities and railways for the planned invasion of Poland. One assignment called for his unit to monitor and provide information about the railway line and tunnel in the Jablunkov Pass, deemed critical for the movement of German troops. Schindler continued to work for the Abwehr until as late as fall 1940, when he was sent to Turkey to investigate corruption among the Abwehr officers assigned to the German embassy there.
Sprawozdanie 6/42 was sent to Polish officials in London by courier and had reached them by 12 November 1942, when it was translated into English and added to another report, "Report on Conditions in Poland". Dated 27 November, this was forwarded to the Polish Embassy in the United States. On 10 December 1942, the Polish Foreign Affairs Minister, Edward Raczyński, addressed the fledgling United Nations on the killings; the address was distributed with the title The Mass Extermination of Jews in German Occupied Poland. He told them about the use of poison gas; about Treblinka, Bełżec and Sobibor; that the Polish underground had referred to them as extermination camps; and that tens of thousands of Jews had been killed in Bełżec in March and April 1942. One in three Jews in Poland were already dead, he estimated, from a population of 3,130,000. Raczyński's address was covered by the New York Times and The Times of London. Winston Churchill received it, and Anthony Eden presented it to the British cabinet. On 17 December 1942, 11 Allies issued the Joint Declaration by Members of the United Nations condemning the "bestial policy of cold-blooded extermination".
While these massacres were happening, the Nazis elsewhere were laying plans for an overall 'solution to the Jewish question'. Death camp operations began in December 1941 at Semlin in Serbia and Chelmno in Poland, where people were killed by exhaust fumes in specially modified vans, which were then driven to nearby sites where the bodies were plundered and burnt. 250,000 Jews were killed this way at Chelmno and 15,000 at Semlin.
Dachau was the concentration camp that was in operation the longest from March 1933 to April 1945, nearly all twelve years of the Nazi regime. Dachau's close proximity to Munich, where Hitler came to power and where the Nazi Party had its official headquarters, made Dachau a convenient location. From 1933 to 1938, the prisoners were mainly German nationals detained for political reasons. After the Reichspogromnacht or Kristallnacht, 30,000 male Jewish citizens were deported to concentration camps. More than 10,000 of them were interned in Dachau alone. As the German military occupied other European states, citizens from across Europe were sent to concentration camps. Subsequently, the camp was used for prisoners of all sorts, from every nation occupied by the forces of the Third Reich.:137
While the labour camps at Auschwitz and Majdanek used inmates for slave labour to support the German war effort, the extermination camps at Belzec, Treblinka, and Sobibor had one task alone: killing. At Treblinka a staff of 120, of whom only 30 were SS (the Nazi paramilitary corps), killed some 750,000 to 925,000 Jews during the camp’s 17 months of operation. At Belzec German records detail a staff of 104, including about 20 SS, who killed some 500,000 Jews in less than 10 months. At Sobibor they murdered between 200,000 and 250,000. These camps began operation during the spring and summer of 1942, when the ghettos of German-occupied Poland were filled with Jews. Once they had completed their missions—murder by gassing, or “resettlement in the east,” to use the language of the Wannsee protocols—the Nazis closed the camps. There were six extermination camps, all in German-occupied Poland, among the thousands of concentration and slave-labour camps throughout German-occupied Europe.
Over the 12 years of use as a concentration camp, the Dachau administration recorded the intake of 206,206 prisoners and deaths of 31,951. Crematoria were constructed to dispose of the deceased. Visitors may now walk through the buildings and view the ovens used to cremate bodies, which hid the evidence of many deaths. It is claimed that in 1942, more than 3,166 prisoners in weakened condition were transported to Hartheim Castle near Linz, and were executed by poison gas because they were deemed unfit.:137
... The notorious Bergen-Belsen concentration camp where 50,000 inmates were supposedly murdered. Actually, about 7,000 inmates died during the period when the camp existed, from 1943 to 1945. Most of them died in the final months of the war as a result of disease and malnutrition -- consequences of the bombings that had completely disrupted normal deliveries of medical supplies and food. The British commander who took control of the camp after the capitulation testified that crimes on a large scale had not taken place at Bergen-Belsen.
From the evidence it became clear how this was done. After a sleepless night – for sleep in the huts was impossible – the men were driven to a hut where the dead were collected. They were instructed by what the witness called the “language of blows, which was universal.” Their duty was to take strips of blankets, tie them to a corpse, and, four men to a corpse, drag it across the main road of the camp along dusty paths to the burial pit. In the midst of this work, which lasted three days without sleep, food, or water till the British arrived, one Hungarian guard at the exit from the hut containing the bodies began shooting all prisoners if they did not come out dragging a body at the double. During the last three days the Hungarian guards were almost continuously shooting at prisoners, sometimes single shots, sometimes fusillades.
