The term "Final Solution" was a euphemism used by the Nazis to refer to their plan for the annihilation of the Jewish people. Historians have shown that the usual tendency of the German leadership was to be extremely guarded when discussing the Final Solution. Euphemisms were, in Mark Roseman's words, "their normal mode of communicating about murder".
From gaining power in January 1933 until the outbreak of war in September 1939, the Nazi persecution of the Jews in Germany was focused on intimidation, expropriating their money and property, and encouraging them to emigrate. According to Nazi Party policy statement, the Jews, and Roma (although numerically fewer), were the only "alien people in Europe". In 1936 the Bureau of Romani Affairs in Munich was taken over by the Interpol and renamed as the Center for Combating the Gypsy Menace. Introduced at the end of 1937, the "final solution of the Gypsy Question" entailed roundups, expulsions, and incarceration of Romani in concentration camps built at Dachau, Buchenwald, Flossenbürg, Mauthausen, Natzweiler, Ravensbruck, Taucha and Westerbork until this point in time. After the Anschluss with Austria in 1938, special offices were established in Vienna and Berlin to "facilitate" Jewish emigration without covert plans for their forthcoming annihilation.
The outbreak of war and the invasion of Poland brought a population of 3.5 million Polish Jews under the control of the Nazi and Soviet security forces, and marked the start of a far more savage persecution, including mass killings. In the German-occupied zone of Poland, Jews were forced into hundreds of makeshift ghettos pending other arrangements. Two years later, with the launch of Operation Barbarossa against the USSR, in late June 1941 the German top echelon began to pursue Hitler's new anti-Semitic plan to eradicate rather than expel Jews. Hitler's earlier ideas about forcible removal of Jews from the German-controlled territories in order to achieve Lebensraum were abandoned after the failure of the air campaign against Britain, initiating a naval blockade of Germany. Reichsführer-SS Heinrich Himmler became the chief architect of a new plan, which came to be called "the Final Solution to the Jewish Question". On 31 July 1941, Reichsmarschall Hermann Göring wrote to Reinhard Heydrich (Himmler's deputy and chief of the RSHA), instructing Heydrich to submit concrete proposals for the implementation of the projected new goal.
Broadly speaking, the extermination of Jews was carried out in two major operations. With the onset of Operation Barbarossa launched from occupied Poland in June 1941, mobile killing units of the SS and Orpo were dispatched to Soviet controlled territories of eastern Poland and further into the Soviet republics for the express purpose of killing all Jews, both Polish and Soviet. During the massive chase after the fleeing Red Army Himmler himself visited Białystok in the beginning of July 1941 and requested that, "as a matter of principle any Jew" behind the German-Soviet frontier "was to be regarded as a partisan". His new orders gave the SS and police leaders full authority for the mass murder behind the front-lines. By August 1941 all Jewish men, women and children were shot. In the second phase of annihilation, the Jewish inhabitants of central, western, and south-eastern Europe were transported by Holocaust trains to camps with newly-built gassing facilities. Raul Hilberg wrote: "In essence, the killers of the occupied USSR moved to the victims, whereas outside this arena, the victims were brought to the killers. The two operations constitute an evolution not only chronologically but also in complexity." Massacres of about one million Jews occurred before plans for the Final Solution were fully implemented in 1942, but it was only with the decision to annihilate the entire Jewish population that extermination camps such as Auschwitz II Birkenau and Treblinka were fitted with permanent gas chambers to kill large numbers of Jews in a relatively short period of time.
The plan to exterminate the Jews of Europe "irrespective of geographic borders" was formalised at the Wannsee Villa near Berlin on 20 January 1942. The conference was chaired by Heydrich and attended by 15 senior officials of the Nazi Party and the German government. Most of those attending were representatives of the Interior Ministry, the Foreign Ministry, and the Justice Ministry, including Ministers for the Eastern Territories. At the conference, Heydrich indicated that approximately 11,000,000 Jews in Europe would fall under the provisions of the "Final Solution". This figure included not only Jews residing in Axis-controlled Europe, but also the Jewish populations of the United Kingdom, and of neutral nations (Switzerland, Ireland, Sweden, Spain, Portugal, and European Turkey). Eichmann's biographer David Cesarani wrote that Heydrich's main purpose in convening the conference was to assert his authority over the various agencies dealing with Jewish issues. "The simplest, most decisive way that Heydrich could ensure the smooth flow of deportations" to death camps, according to Cesarani, "was by asserting his total control over the fate of the Jews in the Reich and the east" under the single authority of the RSHA. A copy of the minutes of this meeting was found by the Allies in March 1947; it was too late to serve as evidence during the first Nuremberg Trial but was used by prosecutor General Telford Taylor in the subsequent Nuremberg Trials.
After the end of World War II, surviving archival documents provided a clear record of the Final Solution policies and actions of Nazi Germany. They included the Wannsee Conference Protocol, which documented the co-operation of various German state agencies in the SS-led Holocaust, as well as some 3,000 tons of original German records captured by Allied armies, including the Einsatzgruppen reports, which documented the progress of the mobile killing units assigned, among other tasks, to kill Jewish civilians during the attack on the Soviet Union in 1941. The evidential proof which documented the mechanism of the Holocaust were submitted at Nuremberg.
The Nazi invasion of the Soviet Union codenamed Operation Barbarossa, which commenced on 22 June 1941, set in motion a "war of destruction" which quickly opened the door to systematic mass murder of European Jews. For Hitler, Bolshevism was merely "the most recent and most nefarious manifestation of the eternal Jewish threat". On 3 March 1941, Wehrmacht Joint Operations Staff Chief Alfred Jodl repeated Hitler's declaration that the "Jewish-Bolshevik intelligentsia would have to be eliminated" and that the forthcoming war would be a confrontation between two completely opposing cultures. In May 1941, Gestapo leader Heinrich Müller wrote a preamble to the new law limiting the jurisdiction of military courts in prosecuting troops for criminal actions because: "this time the troops will encounter an especially dangerous element from the civilian population, therefore, have the right and obligation to secure themselves."
Himmler assembled a force of about 3,000 men from Security Police, Gestapo, Kripo, SD, and the Waffen-SS, as the so-called "special commandos of the security forces", later known as Einsatzgruppen, to eliminate both communists and Jews in occupied territories. These forces were supported by 21 battalions of Orpo Reserve Police under Kurt Daluege, adding up to 11,000 men. The explicit orders given to the Order Police varied between locations, but for Police Battalion 309 in charge of the first mass murder of 5,000 Polish Jews during "Red Friday" in the Soviet-controlled Białystok, Major Weiss explained to his officers that Barbarossa is a war of annihilation against Bolshevism, and that his battalions would proceed ruthlessly against all Jews.
After crossing the Soviet demarcation line in 1941, what had been regarded as exceptional in Nazi Germany became a normal way of operating in the east. The crucial taboo against the killing of women and children was breached not only in Białystok but also in Gargždai in late June. By July, significant numbers of women and children were being killed behind all front lines not only by the Germans but also by the local Ukrainian and Lithuanian auxiliary forces. In late August 1941, the Einsatzgruppen killed 23,600 Jews in the Kamianets-Podilskyi massacre. A month later, the largest mass shooting of Soviet Jews took place on 29–30 September in the ravine of Babi Yar, near Kiev, where more than 33,000 Jewish people of all ages were systematically machine-gunned. In mid-October 1941, HSSPF South, under the command of Friedrich Jeckeln, had reported the indiscriminate killing of more than 100,000 people.
By the end of 1941, before the Wannsee Conference, between 600,000 and 800,000 Jewish people had been murdered and entire regions were reported "free of Jews". By this time, awareness of the Final Solution policy in the east was spreading. Addressing his district governors in the General Government on 16 December 1941, Governor-General Hans Frank said, "But what will happen to the Jews? Do you believe they will be lodged in settlements in Ostland? In Berlin, we were told: why all this trouble; we cannot use them in the Ostland or the Reichskommissariat either; liquidate them yourselves!" Two days later, Himmler recorded the outcome of his discussion with Hitler. The result was: "als Partisanen auszurotten" ("exterminate them as partisans"). Israeli historian Yehuda Bauer says that the remark is probably as close as historians will ever get to a definitive order from Hitler for the genocide carried out during the Holocaust.
Several scholars have suggested that the Final Solution began in the newly formed district of Bezirk Bialystok. The German army took over Białystok within days. On Friday, 27 June 1941, the Reserve Police Battalion 309 arrived in the city and set the Great Synagogue on fire with hundreds of Jewish men locked inside. The burning of the synagogue was followed by a frenzy of killings both inside the homes around the Jewish neighbourhood of Chanajki, and in the city park, lasting until night time. The next day, some 30 wagons of dead bodies were taken to mass graves. As noted by Browning, the killings were led by a commander "who correctly intuited and anticipated the wishes of his Führer" without direct orders. For reasons unknown, the number of victims in the official report by Major Weis was cut in half. The next mass shooting of Polish Jews within the newly formed Reichskommissariat Ostland took place in two days of 5–7 August in occupied Pińsk where over 12,000 Jews died at the hands of Waffen SS, not the Einsatzgruppen. Additional 17,000 Jews perished there in a ghetto uprising crushed a year later with the aid of Belarusian Auxiliary Police.
An Israeli historian Dina Porat claimed that the Final Solution, i.e.: "the systematic overall physical extermination of Jewish communities one after the other – began in Lithuania" during the massive German chase after the Red Army across the Baltic states in Reichskommissariat Ostland. The subject of the Holocaust in Lithuania has been analysed by Konrad Kweit from USHMM who wrote: "Lithuanian Jews were among the first victims of the Holocaust [beyond the eastern borders of occupied Poland]. The Germans carried out the mass executions [...] signaling the beginning of the 'Final Solution'." About 80,000 Jews were killed in Lithuania by October (including in formerly Polish Wilno) and about 175,000 by the end of 1941 according to official reports.
Within one week from the start of Operation Barbarossa, Heydrich issued an order to his Einsatzkommandos for the on-the-spot execution of all Bolsheviks, interpreted by the SS to mean all Jews. One of the first indiscriminate massacres of men, women, and children in Reichskommissariat Ukraine took the lives of over 4,000 Polish Jews in occupied Łuck on 2–4 July 1941, murdered by Einsatzkommando 4a assisted by the Ukrainian People's Militia. Formed officially on 20 August 1941, the Reichskommissariat Ukraine – stretching from prewar east-central Poland to Crimea – had become operational theatre of the Einsatzgruppe C. Within the Soviet Union proper, between 9 July 1941 and 19 September 1941 the city of Zhytomyr was made Judenfrei in three murder operations conducted by German and Ukrainian police in which 10,000 Jews perished. In the Kamianets-Podilskyi massacre of 26–28 August 1941 some 23,600 Jews where shot in front of open pits (including 14,000–18,000 people expelled from Hungary). After an incident in Bila Tserkva in which 90 small children left behind had to be shot separately, Blobel requested that Jewish mothers hold them in their arms during mass shootings. Long before the conference at Wannsee, 28,000 Jews were shot by SS and Ukrainian military in Vinnytsia on 22 September 1941, followed by the 29 September massacre of 33,771 Jews at Babi Yar. In Dnipropetrovsk, on 13 October 1941 some 10,000–15,000 Jews were shot. In Chernihiv, 10,000 Jews were put to death and only 260 Jews were spared. In mid-October, during the Krivoy-Rog massacre of 4,000–5,000 Soviet Jews the entire Ukrainian auxiliary police force actively participated. In the first days of January 1942 in Kharkiv, 12,000 Jews were murdered, but smaller massacres continued in this period on daily basis in countless other locations. In August 1942 in the presence of only a few German SS men over 5,000 Jews were massacred in Polish Zofjówka by the Ukrainian Auxiliary Police leading to town's complete sweep from existence.
Historians find it difficult to determine precisely when the first concerted effort at annihilation of all Jews began in the last weeks of June 1941 during Operation Barbarossa. Dr. Samuel Drix (Witness to Annihilation), Jochaim Schoenfeld (Holocaust Memoirs), and several survivors of the Janowska concentration camp, who were interviewed in the film Janovska Camp at Lvov, among other witnesses, have argued that the Final Solution began in Lwów (Lemberg) in Distrikt Galizien of the General Government during the German advance across the Soviet occupied Poland. Statements and memoirs of survivors emphasize that, when Ukrainian nationalists and ad hoc Ukrainian People's Militia (soon reorganized as the Ukrainian Auxiliary Police) began to murder women and children rather than only male Jews, the "Final Solution" had begun. Witnesses have said that such murders happened both prior to and during the pogroms reportedly triggered by the NKVD prisoner massacre. The question of whether there was some coordination between the Lithuanian and Ukrainian militias remains open (i.e. collaborating for a joint assault in Kovno, Wilno, and Lwów).
The killings continued uninterrupted. On 12 October 1941 in Stanisławów, some 10,000–12,000 Jewish men, women, and children were shot at the Jewish cemetery by the German uniformed SS-men and Ukrainian Auxiliary Police during the so-called "Bloody Sunday" (de). The shooters began firing at 12 noon and continued without stopping by taking turns. There were picnic tables set up on the side with bottles of vodka and sandwiches for those who needed to rest from the deafening noise of gunfire. It was the single largest massacre of Polish Jews in Generalgouvernement prior to mass gassings of Aktion Reinhard, which commenced at Bełżec in March 1942. Notably, the extermination operations in Chełmno had begun on 8 December 1941, one-and-a-half month before Wannsee, but Chełmno – located in Reichsgau Wartheland – was not a part of Reinhard, and neither was Auschwitz-Birkenau functioning as an extermination center until November 1944 in Polish lands annexed by Hitler and added to Germany proper.
The conference at Wannsee gave impetus to the so-called second sweep of the Holocaust by the bullet in the east. Between April and July 1942 in Volhynia, 30,000 Jews were murdered in death pits with the help of dozens of newly formed Ukrainian Schutzmannschaft. Owing to good relations with the Ukrainian Hilfsverwaltung, these auxiliary battalions were deployed by the SS also in Russia Center, Russia South, and in Byelorussia; each with about 500 soldiers divided into three companies. They participated in the extermination of 150,000 Volhynian Jews alone, or 98 percent of the Jewish inhabitants of the entire region. In July 1942 the Completion of the Final Solution in the General Government territory which included Distrikt Galizien, was ordered personally by Himmler. He set the initial deadline for 31 December 1942.
When in 1941 the Wehrmacht forces attacked the Soviet positions in eastern Poland during the initially successful Operation Barbarossa, the area of the General Government was enlarged by the inclusion of regions that had been occupied by the Red Army since 1939. The killings of Jews from the Łódź Ghetto in the Warthegau district began in early December 1941 with the use of gas vans [approved by Heydrich] at the Kulmhof extermination camp. The deceptive guise of "Resettlement in the East" organised by SS Commissioners, was also tried and tested at Chełmno. By the time the European-wide Final Solution was formulated two months later, Heydrich's RSHA had already confirmed the effectiveness of industrial killing by exhaust fumes, and the strength of deception.
Construction work on the first killing centre at Bełżec in occupied Poland began in October 1941, three months before the Wannsee Conference. The new facility was operational by March the following year. By mid-1942, two more death camps had been built on Polish lands: Sobibór operational by May 1942, and Treblinka operational in July. From July 1942, the mass murder of Polish and foreign Jews took place at Treblinka as part of Operation Reinhard, the deadliest phase of the Final Solution. More Jews were killed at Treblinka than at any other Nazi extermination camp apart from Auschwitz. By the time the mass killings of Operation Reinhard ended in 1943 roughly two million Jews in the German-occupied Poland have been murdered. The total number of people killed in 1942 in Lublin/Majdanek, Bełżec, Sobibór, and Treblinka was 1,274,166 by Germany's own estimation, not counting Auschwitz II Birkenau nor Kulmhof. Their bodies were buried in mass graves initially. Both Treblinka and Bełżec were equipped with powerful crawler excavators from Polish construction sites in the vicinity, capable of most digging tasks without disrupting surfaces. Although other methods of extermination, such as the cyanic poison Zyklon B, were already being used at other Nazi killing centres such as Auschwitz, the Aktion Reinhard camps used lethal exhaust gases from captured tank engines.
The Holocaust by bullets (as opposed to the Holocaust by gas) went on in the territory of occupied Poland in conjunction with the ghetto uprisings, irrespective of death camps' quota. In two weeks of July 1942 the Słonim Ghetto revolt crushed with the help of Latvian, Lithuanian and Ukrainian Schutzmannschaft cost the lives of 8,000–13,000 Jews. The second largest mass shooting (to that particular date) took place in late October 1942 when the insurgency was suppressed in the Pińsk Ghetto; over 26,000 men, women and children where shot with the aid of Belarusian Auxiliary Police before the ghetto's closure. During the suppression of the Warsaw Ghetto Uprising (the largest single revolt by Jews during World War II), 13,000 Jews were killed in action before May 1943. Numerous other uprisings were quelled without impacting the pre-planned Nazi deportations actions.
About two-thirds of the overall number of victims of the Final Solution were killed before February 1943, which included the main phase of the extermination programme in the West launched by Eichmann on 11 June 1942 from Berlin. The Holocaust trains run by the Deutsche Reichsbahn and several other national railway systems delivered condemned Jewish captives from as far as Belgium, Bulgaria, France, Greece, Hungary, Italy, Moravia, Netherlands, Romania, Slovakia, and even Scandinavia. The cremation of exhumed corpses to destroy any evidence left behind began in early spring and continued throughout summer. The nearly completed clandestine programme of murdering all deportees was explicitly addressed by Heinrich Himmler in his Posen speeches made to the leadership of the Nazi Party on 4 October and during the Posen Conference of 6 October 1943 in occupied Poland. Himmler explained why the Nazi leadership found it necessary to kill Jewish women and children along with the Jewish men. The assembled functionaries were told that the Nazi state policy was "the extermination of the Jewish people" as such.
We were faced with the question: what about the women and children? – I have decided on a solution to this problem. I did not consider myself justified to exterminate the men only – in other words, to kill them or have them killed while allowing the avengers, in the form of their children, to grow up in the midst of our sons and grandsons. The difficult decision had to be made to have this people disappear from the earth. — Heinrich Himmler, 6 October 1943
On 19 October 1943, five days after the prisoner revolt in Sobibór, Operation Reinhard was terminated by Odilo Globocnik on behalf of Himmler. The camps responsible for the killing of nearly 2,700,000 Jews were soon closed. Bełżec, Sobibór, and Treblinka were dismantled and ploughed over before spring. The operation was followed by the single largest German massacre of Jews in the entire war carried out on 3 November 1943; with approximately 43,000 prisoners shot one-by-one simultaneously in three nearby locations by the Reserve Police Battalion 101 hand-in-hand with the Trawniki men from Ukraine. Auschwitz alone had enough capacity to fulfill the Nazis' remaining extermination needs.
Unlike Belzec, Sobibor, Treblinka, and Lublin-Majdanek, which were built in the occupied General Government territory inhabited by the largest concentrations of Jews, the killing centre at Auschwitz subcamp of Birkenau operated in Polish areas annexed by Nazi Germany directly. The new gas chambers at Bunker I were finished around March 1942 when the Final Solution was officially launched at Belzec. Until mid-June 20,000 Silesian Jews were killed there using Zyklon B. In July 1942 Bunker II became operational. In August, another 10,000-13,000 Polish Jews from Silesia perished, along with 16,000 French Jews declared 'stateless', and 7,700 Jews from Slovakia.
The infamous 'Gate of Death' at Auschwitz II for the incoming freight trains was built of brick and cement mortar in 1943, and the three-track rail spur was added. Until mid-August, 45,000 Thessaloniki Jews were murdered in mere six months, including over 30,000 Jews from Sosnowiec (Sosnowitz) and Bendzin Ghettos. The spring of 1944 marked the beginning of the last phase of the Final Solution at Birkenau. The new big ramps and sidings were constructed, and two freight elevators were installed inside Crematoria II and III for moving the bodies faster. The size of the Sonderkommando was nearly quadrupled in preparation for the Special Operation Hungary (Sonderaktion Ungarn). In May 1944 Auschwitz-Birkenau became the site of one of the two largest mass murder operations in modern history following the Großaktion Warschau deportations of the Warsaw Ghetto inmates to Treblinka in 1942. It is estimated that until July 1944 approximately 320,000 Hungarian Jews were gassed at Birkenau in less than eight weeks. The entire operation was photographed by the SS.
Historians disagree as to when and how did the Nazi leadership decide that the European Jews should be exterminated. The controversy is commonly described as the functionalism versus intentionalism debate which began in the 1960s, and subsided thirty years later. In the 1990s the attention of mainstream historians moved away from the question of top executive orders triggering the Holocaust, and focused on factors which were overlooked earlier such as personal initiative and ingenuity of countless functionaries in charge of the killing fields. No written evidence of Hitler ordering the Final Solution has ever been found to serve as a "smoking gun" and therefore this one particular question remains unanswered.
Hitler made numerous chilling predictions regarding the Holocaust of the Jews of Europe prior to the beginning of World War II. During a speech given on 30 January 1939, on the sixth anniversary of his accession to power, Hitler said:
Today I will once more be a prophet: If the international Jewish financiers in and outside Europe should succeed in plunging the nations once more into a world war, then the result will not be the Bolshevization of the earth, and thus the victory of Jewry, but the annihilation of the Jewish race in Europe! — Adolf Hitler, 1939
Raul Hilberg, in his book The Destruction of the European Jews, was the first historian to systematically document and analyse the Nazi project to kill every Jew in Europe. The book was initially published in 1961, and issued in an enlarged version in 1985.
Hilberg's analysis of the steps that led to the destruction of European Jews revealed that it was "an administrative process carried out by bureaucrats in a network of offices spanning a continent". Hilberg divides this bureaucracy into four components or hierarchies: the Nazi Party, the civil service, industry, and the Wehrmacht armed forces – but their cooperation is viewed as "so complete that we may truly speak of their fusion into a machinery of destruction". For Hilberg, the key stages in the destruction process were: definition and registration of the Jews; expropriation of property; concentration into ghettoes and camps; and, finally, annihilation. Hilberg gives an estimate of 5.1 million as the total number of Jews killed. He breaks this figure down into three categories: Ghettoization and general privation: over 800,000; open-air shootings: over 1,300,000; extermination camps: up to 3,000,000.
With respect to the "functionalism versus intentionalism" debate about a master plan for the Final Solution, or the lack thereof, Hilberg posits what has been described as "a kind of structural determinism". Hilberg argues that "a destruction process has an inherent pattern" and the "sequence of steps in a destruction process is thus determined". If a bureaucracy is motivated "to inflict maximum damage upon a group of people", it is "inevitable that a bureaucracy—no matter how decentralized its apparatus or how unplanned its activities—should push its victims through these stages", culminating in their annihilation.
In his monograph, The Origins Of The Final Solution: The Evolution of Nazi Jewish Policy, September 1939 – March 1942, Christopher Browning argues that Nazi policy toward the Jews was radicalized twice: in September 1939, when the invasion of Poland implied policies of mass expulsion and massive loss of Jewish lives; and in spring 1941, when preparation for Operation Barbarossa involved the planning of mass execution, mass expulsion, and starvation – to dwarf what had happened in Jewish Poland.
Browning believes that the "Final Solution as it is now understood—the systematic attempt to murder every last Jew within the German grasp" took shape during a five-week period, from 18 September to 25 October 1941. During this time: the sites of the first extermination camps were selected, different methods of killing were tested, Jewish emigration from the Third Reich was forbidden, and 11 transports departed for Łódź as a temporary holding station. During this period, Browning writes, "The vision of the Final Solution had crystallised in the minds of the Nazi leadership and was being turned into reality." This period was the peak of Nazi victories against the Soviet Army on the Eastern Front, and, according to Browning, the stunning series of German victories led to both an expectation that the war would soon be won, and the planning of the final destruction of the Jewish-Bolshevik enemy.
Browning describes the creation of the extermination camps, which were responsible for the largest number of deaths in the Final Solution, as bringing together three separate developments within the Third Reich: the concentration camps which had been established in Germany since 1933; an expansion of the gassing technology of the Nazi euthanasia programme to provide killing mechanism of greater efficiency and psychological detachment; and the creation of "factories of death" to be fed endless streams of victims by mass uprooting and deportation that utilized the experience and personnel from earlier population resettlement programmes—especially the HSSPF and Adolf Eichmann's RSHA for "Jewish affairs and evacuations".
Peter Longerich argues that the search for a finite date on which the Nazis embarked upon the extermination of the Jews is futile, in his book Holocaust: The Nazi Persecution and Murder of the Jews (2011). Longerich writes: "We should abandon the notion that it is historically meaningful to try to filter the wealth of available historical material and pick out a single decision" that led to the Holocaust.
Timothy Snyder writes that Longerich "grants the significance of Greiser's murder of Jews by gas at Chełmno in December 1941", but also detects a significant moment of escalation in spring 1942, which includes "the construction of the large death factory at Treblinka for the destruction of the Warsaw Jews, and the addition of a gas chamber to the concentration camp at Auschwitz for the murder of the Jews of Silesia". Longerich suggests that it "was only in the summer of 1942, that mass killing was finally understood as the realization of the Final Solution, rather than as an extensively violent preliminary to some later program of slave labor and deportation to the lands of a conquered USSR". For Longerich, to see mass killing as the Final Solution was an acknowledgement by the Nazi leadership that there would not be a German military victory over the USSR in the near future.
David Cesarani emphasises the improvised, haphazard nature of Nazi policies in response to changing war time conditions in his overview, Final Solution: The Fate Of The European Jews 1933-49. "Cesarani provides telling examples", wrote Mark Roseman, "of a lack of coherence and planning for the future in Jewish policy, even when we would most expect it. The classic instance is the invasion of Poland in 1939, when not even the most elementary consideration had been given to what should happen to Poland’s Jews either in the shorter or longer term. Given that Poland was home to the largest Jewish population in the world, and that in a couple of years it would house the extermination camps, this is remarkable."
Whereas Christopher Browning places the Nazi plan to exterminate the Jews in the context of the Wehrmacht victories on the Eastern front, Cesarani argues that the German subsequent realisation that there would be no swift victory over the Soviet Union "scuppered the last territorial 'solution' still on the table: expulsion to Siberia." Germany's declaration of war on the United States on December 11, 1941, "meant that holding European Jews hostage to deter the US from entering the conflict was now pointless. As Joseph Goebbels put it when he summarised a secret speech Hitler made on 12 December 1941: 'The world war is here, the destruction of the Jews must be the inevitable consequence'." Cesarani concludes, the Holocaust "was rooted in antisemitism but it was shaped by war". The fact that the Nazis were, ultimately, so successful in killing between five and six million Jews was not due to the efficiency of the Third Reich or the clarity of their policies. "Rather, the catastrophic rate of killing was due to German persistence… and the duration of the murderous campaigns. This last factor was largely a consequence of allied military failure."
The entry of the U.S. into the War is also crucial to the time-frame proposed by Christian Gerlach who argued in his 1997 thesis, that the Final Solution decision was announced on 12 December 1941, when Hitler addressed a meeting of the Nazi Party (the Reichsleiter) and of regional party leaders (the Gauleiter). The day after Hitler's speech, on 13 December 1941 Joseph Goebbels wrote in his diary:
With respect of the Jewish Question, the Führer has decided to make a clean sweep. He prophesied to the Jews that if they again brought about a world war, they would see their annihilation in it. That wasn't just a catch-word. The world war is here and the annihilation of the Jews must be the necessary consequence.
Cesarani notes that by 1943, as the military position of the German forces deteriorated, the Nazi leadership became more openly explicit about the Final Solution. In March, Goebbels confided to his diary: "On the Jewish question especially, we are in it so deeply that there is no getting out any longer. And that is a good thing. Experience teaches that a movement and a people who have burned their bridges fight with much greater determination and fewer constraints than those that have a chance of retreat."
When Himmler addressed senior SS personnel and leading members of the regime in Posen on October 4, 1943, he used "the fate of the Jews as a sort of blood bond to tie the civil and military leadership to the Nazi cause."
Today I am going to refer quite frankly to a very grave chapter. We can mention it now among ourselves quite openly and yet we shall never talk about it in public. I'm referring to the evacuation of the Jews, the extermination of the Jewish people. Most of you will know what it's like to see 100 corpses side by side or 500 corpses or 1,000 of them. To have coped with this and—except for cases of human weakness—to have remained decent, that has made us tough. This is an unwritten—never to be written—and yet glorious page in our history.
Journalist Ron Rosenbaum, in his book Explaining Hitler: The Search for the Origins of His Evil, found that the phrase "final solution" had been used much earlier. An investigative report by the Münchener Post, a socialist newspaper that was an early opponent of Hitler, found as early as 1931 Nazi Party and SA documents using the phrase as part of a description of plans for what became the Nuremberg Laws and a suggestion that "for the final solution of the Jewish question it is proposed to use the Jews in Germany for slave labor or for cultivation of the German swamps administered by a special SS division".
