Beginning with the British air raids on Cologne in May of 1942, the Allies launched a strategic bombing campaign that would target cities and industrial plants across the Reich for the next three years. In the summer of 1942, Germany and its allies focused on the Soviet Union unsuccessfully. The Soviet Union gained the dominant role, which it would maintain for the rest of the war.
Schlieffen's ideas were largely aimed at operational-level leaders, that is, the commanders of Germany's divisions and army corps. The biggest problems in World War One, however, were at the lower, tactical level. And the German solution to these problems was to apply Schlieffen's operational principles to small units as well as to large ones. Thus, by decentralising command and by increasing the firepower of the infantry, they created a large number of platoon-sized units capable of independent action on the battlefield.
Concentration camps began to incarcerate ‘habitual criminals’ in addition to political prisoners. Goebbels stepped up anti-Semitic propaganda with a traveling exhibition which cast Jews as the enemy. Nearly half a million people attended. Some guessed worse would come. Winston Churchill criticised British relations with Germany, warning of ‘great evils of racial and religious intolerance’, though many colleagues complained of his ‘harping on’ about Jews.
On September 21, 1939, Reinhard Heydrich ordered the establishment of the Judenräte (“Jewish Councils”), comprising up to 24 men—rabbis and Jewish leaders. Heydrich’s order made these councils personally responsible in “the literal sense of the term” for carrying out German orders. When the Nazis sealed the Warsaw Ghetto, the largest of German-occupied Poland’s 400 ghettos, in the fall of 1940, the Jews—then 30 percent of Warsaw’s population—were forced into 2.4 percent of the city’s area. The ghetto’s population reached a density of more than 200,000 persons per square mile (77,000 per square km) and 9.2 per room. Disease, malnutrition, hunger, and poverty took their toll even before the first bullet was fired.
The prisoners' days began at 4:30 am for the men (an hour later in winter), and earlier for the women, when the block supervisor sounded a gong and started beating inmates with sticks to encourage them to wash and use the latrines quickly. Sanitary arrangements were atrocious, with few latrines and a lack of clean water. Each washhouse had to service thousands of prisoners. In sectors BIa and BIb in Auschwitz II-Birkenau, two buildings containing latrines and washrooms were installed in 1943. These contained troughs for washing and 90 faucets; the toilet facilities were "sewage channels" covered by concrete with 58 holes for seating. There were three barracks with washing facilities or toilets to serve 16 residential barracks in BIIa, and six washrooms/latrines for 32 barracks in BIIb, BIIc, BIId, and BIIe. Primo Levi described a 1944 Auschwitz III washroom:
A memorandum dated July 31, 1941, from Hitler’s top commander Hermann Goering to Reinhard Heydrich, chief of the SD (the security service of the SS), referred to the need for an Endlösung (final solution) to “the Jewish question.” Beginning in September 1941, every person designated as a Jew in German-held territory was marked with a yellow star, making them open targets. Tens of thousands were soon being deported to the Polish ghettoes and German-occupied cities in the USSR.
The history of Auschwitz-Birkenau as an extermination center is complex. From late 1941 to October 1942, the mortuary at Auschwitz main camp, which was already equipped with a crematorium, was adapted as a gas chamber. It measured approximately 835 square feet. In the spring of 1942, two provisional gas chambers at Birkenau were constructed out of peasant huts, known as the 'bunkers'.
The mass killings of Jews in the occupied Soviet territories were assigned to four SS formations called Einsatzgruppen ("task groups"), which were under Heydrich's overall command. Similar formations had been used to a limited extent in Poland in 1939, but the ones operating in the Soviet territories were much larger. The Einsatzgruppen's commanders were ordinary citizens: the great majority were professionals and most were intellectuals. By the winter of 1941–1942, the four Einsatzgruppen and their helpers had killed almost 500,000 people. The largest massacre of Jews by the mobile killing squads in the Soviet Union was at a ravine called Babi Yar outside Kiev, where 33,771 Jews were killed in a single operation on 29–30 September 1941.[n] A mixture of SS and Security Police, assisted by Ukrainian police, carried out the killings. Although they did not actively participate in the killings, men of the German 6th Army helped round up the Jews of Kiev and transport them to be shot. By the end of the war, around two million are thought to have been victims of the Einsatzgruppen and their helpers in the local population and the German Army. Of those, about 1.3 million were Jews and up to a quarter of a million Roma.
In March 1951, the government of Israel requested $1.5 billion from the Federal Republic of Germany to finance the rehabilitation of 500,000 Jewish survivors, arguing that Germany had stolen $6 billion from the European Jews. Israelis were divided about the idea of taking money from Germany. The Conference on Jewish Material Claims Against Germany (known as the Claims Conference) was opened in New York, and after negotiations, the claim was reduced to $845 million.
In the summer of 1942, when Germany launched another offensive in the southern USSR against Stalingrad and the Caucasus, the Soviets again lost tremendous amounts of territory, only to counter-attack once more during winter. German gains were ultimately limited by Hitler diverting forces from the attack on Stalingrad itself and seeking to pursue a drive to the Caucasus oilfields simultaneously as opposed to subsequently as the original plan had envisaged.
Anti-Jewish measures were introduced in Slovakia, which would later deport its Jews to German concentration and extermination camps. Bulgaria introduced anti-Jewish measures in 1940 and 1941, including the requirement to wear a yellow star, the banning of mixed marriages, and the loss of property. Bulgaria annexed Thrace and Macedonia, and in February 1943 agreed to deport 20,000 Jews to Treblinka; all 11,000 Jews from the annexed territories were sent to their deaths, and plans were made to deport an additional 6,000–8,000 Bulgarian Jews from Sofia to meet the quota. When the plans became public, the Orthodox Church and many Bulgarians protested, and King Boris III canceled the deportation of Jews native to Bulgaria. Instead, they were expelled to the interior pending further decision. Although Hungary expelled Jews who were not citizens from its newly annexed lands in 1941, it did not deport most of its Jews until the German invasion of Hungary in March 1944. Between 15 May and 9 July 1944, 440,000 Hungarian Jews were deported to Auschwitz. In late 1944 in Budapest, nearly 80,000 Jews were killed by the Hungarian Arrow Cross battalions.
After invading Poland, the Germans established ghettos in the incorporated territories and General Government to confine Jews. The ghettos were formed and closed off from the outside world at different times and for different reasons. For example, the Łódź ghetto was closed in April 1940, to force the Jews inside to give up money and valuables; the Warsaw ghetto was closed for health considerations (for the people outside, not inside, the ghetto), but this did not happen until November 1940; and the Kraków ghetto was not established until March 1941. The Warsaw Ghetto contained 380,000 people and was the largest ghetto in Poland; the Łódź Ghetto was the second largest, holding between 160,000 to 223,000. 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.
The vital industries and transportation centers that would be targeted for shutdown were valid military targets. Civilians were not to be targeted directly, but the breakdown of production would affect their morale and will to fight. German legal scholars of the 1930s carefully worked out guidelines for what type of bombing was permissible under international law. While direct attacks against civilians were ruled out as "terror bombing", the concept of the attacking the vital war industries – and probable heavy civilian casualties and breakdown of civilian morale – was ruled as acceptable.
His tasks for the Abwehr included collecting information on railways, military installations, and troop movements, as well as recruiting other spies within Czechoslovakia, in advance of a planned invasion of the country by Nazi Germany. He was arrested by the Czech government for espionage on 18 July 1938 and immediately imprisoned, but was released as a political prisoner under the terms of the Munich Agreement, the instrument under which the Czech Sudetenland was annexed into Germany on 1 October. Schindler applied for membership in the Nazi Party on 1 November and was accepted the following year.
