Arthur Nebe

Born in Berlin in 1894, the son of a Berlin school teacher, Nebe volunteered for military service and served with distinction during World War I.[1] In 1920 Nebe joined the Berlin detective force, the Kriminalpolizei (Kripo; Criminal Police). He attained the rank of a police inspector in 1923 and the rank of Police Commissioner in 1924.[2][3]

Nebe was a "conservative nationalist", who embraced the shift of the country "to the right in the 1930s".[2] In July 1931, he joined the Nazi Party (NSDAP number 574,307) and the Schutzstaffel (SS number 280,152).[4] Nebe became the Nazis' liaison in the Berlin criminal police, with links to an early Berlin SS group led by Kurt Daluege. In early 1932, Nebe and other Nazi detectives formed the NS (National Socialist) Civil Service Society of the Berlin Police.[2] In 1933 he came to know Hans Bernd Gisevius, then an official in the Berlin Police Headquarters; after the war, Gisevius produced an apologetic account of Nebe's Nazi era activities. In 1935 Nebe was appointed head of Prussian Criminal Police.[5] He later obtained the rank of SS-Gruppenführer, an SS equivalent to the rank of a police general.[4]

In July 1936, the Prussian Criminal Police became the central criminal investigation department for Germany, the Reichskriminalpolizeiamt. It was amalgamated, along with the secret state police, the Geheime Staatspolizei (Gestapo), into the Sicherheitspolizei (SiPo), with Reinhard Heydrich in overall command. Nebe was appointed head of the Reichskriminalpolizeiamt, reporting to Heydrich.[6] The addition of the Kripo to Heydrich's control helped cement the foundations of the police state. It also led to an "overlap" of personnel from the SD, Gestapo and Kripo to leadership positions in the police and security forces in Germany.[7]

On 27 September 1939, Himmler ordered the creation of the Reich Main Security Office (Reichssicherheitshauptamt or RSHA); the new organisation encompassed the intelligence service, security services, secret state and criminal police. The RSHA was divided into main departments, including the Kripo, which became Department V of the RSHA.[8] Department V was also known as the Reich Criminal Police Office (Reichskriminalpolizeiamt, or RKPA). Kripo's stated mission, which Nebe embraced, was to "exterminate criminality". Under his leadership, equipped with arbitrary powers of arrest and detention, the Kripo acted more and more like the Gestapo, including the liberal use of so-called protective custody and large-scale roundups of "asocials".[9]

In 1939, Nebe lent a commissioner in his Criminal Police Office, Christian Wirth of Stuttgart, to the euthanasia organisation, which ran the programme of involuntary euthanasia of the disabled.[10] Also in 1939, as head of Kripo, he was involved in the discussions around the upcoming campaigns against the Sinti and Roma. Nebe wanted to include sending Berlin's Gypsies to the planned reservations for the Jews and others in the east.[11] In October 1939, Nebe ordered Adolf Eichmann to put Gypsies with Jews on the transports to Nisko.[12] In November, Nebe led the onsite investigation into Georg Elser's failed assassination attempt on Hitler.

Just prior to the 1941 Nazi invasion of the Soviet Union in Operation Barbarossa, the Einsatzgruppen mobile death squads which had operated in Poland were reformed and placed once again under the overall command of Reinhard Heydrich. Nebe volunteered to command Einsatzgruppe B, which operated behind Army Group Center after the invasion of the Soviet Union. The unit's task was to exterminate Jews and other "undesirables", such as communists, Gypsies, "Asiatics", the disabled, and psychiatric hospital patients in the territories that the Wehrmacht had overrun. The Einsatzgruppen also shot hostages and prisoners of war handed over by the army for execution.[13][14]

Around 5 July 1941, Nebe consolidated Einsatzgruppe B near Minsk, establishing a headquarters and remaining there for two months. The killing activities progressed apace. In a 13 July Operational Situation Report, Nebe stated that 1,050 Jews had been killed in Minsk, and that in Vilna, the liquidation of the Jews was underway, and that five hundred Jews were shot daily.[15] In the same report Nebe remarked that: "only 96 Jews were executed in Grodno and Lida during the first days. I gave orders to intensify these activities". He also reported that the killings were being brought into smooth running order and that the shootings were carried out "at an increasing rate". The report also announced that in Minsk Einsatzgruppe was now killing non-Jews.[16][17]

In the 23 July report, Nebe advanced the idea of a "solution to the Jewish problem" being "impractical" in his region of operation due to "the overwhelming number of the Jews"; there were too many Jews to be killed by too few men.[18] By August 1941, Nebe came to realize that his Einsatzgruppe's resources were insufficient to meet the expanded mandate of the killing operations, resulting from the inclusion of Jewish women and children since that month.[19]

In August 1941, Himmler vomited after a demonstration of a mass-shooting of Jews in Minsk arranged by Nebe. Regaining his composure, Himmler decided that alternative methods of killing should be found.[20] He told Heydrich that he was concerned for the mental health of the SS men.[21] Himmler turned to Nebe to devise a more "convenient" method of killing, particularly one that would spare executioners elements of their grisly task. Murder with carbon monoxide gas, already in use in the Reich as part of the euthanasia program, was contemplated, but deemed too cumbersome for the mobile killing operations in the occupied Soviet Union.[22]

Nebe decided to try experimenting by murdering Soviet mental patients, first with explosives near Minsk, and then with automobile exhaust at Mogilev.[12] The idea of using gas was partly inspired by an incident in Nebe's past. One night after a party, Nebe had driven home drunk, parked in his garage, and fallen asleep with the engine running, thus nearly dying of carbon monoxide poisoning from the exhaust fumes.[23] To conduct the experiments, he ordered chemist Albert Widmann, a member of the criminal-technical institute of the RKPA, to come to Minsk with 250 kilograms (550 lb) of explosives and exhaust hoses. The next day Widmann, Nebe, and an explosives expert carried out their first experiment in prepared bunkers in the Minsk area. According to testimony presented at Widmann's postwar trial:

One of the bunkers was loaded with explosives and 24 mental patients were put into it. Nebe gave the signal to detonate, but the resultant explosion failed to kill the patients. Several of them emerged from the bunker covered in blood and screaming loudly. Thereupon more explosives were brought up, the wounded patients were forced back into the bunker, and a second explosion finally finished the job. The bunker had become quiet and parts of bodies could be seen hanging from nearby trees.[12]

Two days later, Nebe and Widmann carried out another killing experiment: five psychiatric patients from Mogilev were placed in a hermetically sealed room, with pipes leading to the outside. At first, exhausts from a passenger vehicle were vented into the room, so that the carbon monoxide would kill those inside. However, this method failed to kill the patients, so a truck was added; the patients were dead within 15 minutes. Nebe and Widmann concluded that killing with explosives was impractical, while gassing "held promise", as vehicles were readily available, and could be used as needed.[24]

After these experimental killings, Nebe thought of remodelling a vehicle with a hermetically sealed cabin for killing. The carbon monoxide from the vehicle's exhaust would be channelled into the sealed cabin in which the victims stood. He discussed the technical aspects of the idea with a specialist from Kripo's Technology Institute and together they brought the proposal before Heydrich, who adopted it.[25]

The Wehrmacht's aggressive rear security doctrine, and the use of the "security threat" to disguise genocidal policies, resulted in close cooperation between the army and the security apparatus behind the front lines. Nebe, as the Einsatzgruppe B commander, participated in a three-day field conference at Mogilev in late September 1941. Organised by General Max von Schenckendorff, chief of Army Group Centre's rear area, the conference was to serve as an "exchange of experiences" for the Wehrmacht rear unit commanders.[26]

Participating officers were selected on the basis of their "achievements and experiences" in security operations already undertaken.[27] In addition to Nebe, the speakers included: Higher SS and Police Leader Erich von dem Bach-Zelewski; Max Montua, commander of Police Regiment Center; Hermann Fegelein, commander of the SS Cavalry Brigade; and Gustav Lombard, commander of the 1st SS Cavalry Regiment. Nebe's talk focused on the role of the SD in the common fight against "partisans" and "plunderers". He also covered the "Jewish question", with particular consideration to the anti-partisan movement.[28][29] Following the conference, a 16-page executive summary was distributed to the Wehrmacht troops and police units in the rear area. There was a dramatic increase in atrocities against Jews and other civilians in the last three months of 1941.[30]

Under Nebe's command, Einsatzgruppe B committed public hangings to terrorise the local population. An Einsatzgruppe B report, dated 9 October 1941, stated that, due to suspected partisan activity near Demidov, all male residents aged fifteen to fifty-five were put in a camp to be screened. Seventeen people were identified as "partisans" and "Communists" and five were hanged in front of 400 local residents assembled to watch; the rest were shot.[31] Through 14 November 1941, Einsatzgruppe B reported the killing of 45,467 people; thereafter, Nebe returned to Berlin and resumed his duties as head of the Kripo.[32]

Following the assassination of Heydrich, Nebe assumed the additional post of President of the International Criminal Police Commission, the organization today known as Interpol, in June 1942. After the Anschluss in 1938, the organization had fallen under the control of Nazi Germany and was headed by Heydrich until his death. Nebe served in this capacity until June 1943, when he was replaced by Ernst Kaltenbrunner.[33]

In March 1944, after the "Great Escape" from Stalag Luft III prisoner-of-war camp, Nebe was ordered by Heinrich Müller, Chief of the Gestapo, to select and kill fifty of the seventy-three recaptured prisoners in what became known as the "Stalag Luft III murders".[34] Also in 1944, Nebe suggested that the Roma interned at Auschwitz would be good subjects for medical experiments at the Dachau concentration camp, after Himmler had asked Ernst-Robert Grawitz, a high-ranking SS physician, for advice.[12]

Nebe was involved in the July 20 plot against Adolf Hitler; he was to lead a team of twelve policemen to kill Himmler, but the signal to act never reached him.[35] After the failed assassination attempt, Nebe fled and went into hiding on an island in the Wannsee. He was arrested in January 1945, after a former mistress betrayed him. Nebe was sentenced to death by the People's Court on 2 March and, according to official records, was executed in Berlin at Plötzensee Prison on 21 March 1945 by being hanged with piano wire from a meat hook, in accordance with Hitler's order that the bomb plotters were to be "hanged like cattle".[3][36]

Several apologetic accounts produced by the conspirators behind the 20 July plot described Nebe as a professional police officer and a dedicated member of the German resistance. In 1947, Hans Gisevius described Nebe's position at the head of Einsatzgruppe B as a "brief command at the front". Gisevius changed his story in the 1960s, when Nebe's role with the Einsatzgruppen was exposed. In Wo ist Nebe? (Where is Nebe [1966]), Gisevius claimed that Nebe was reluctant to accept the posting but had been persuaded to take it by the opposition leaders Hans Oster and Ludwig Beck, who had allegedly wanted Nebe to retain a key role in Heydrich's apparatus. Gisevius also claimed that Nebe exaggerated the number of victims in reports to Berlin by adding a zero to the number of those killed.[43] In addition, a Swedish police official active in the Interpol during the war years, Harry Söderman, described Nebe and Karl Zindel, a key RSHA figure responsible for persecution of the Roma, in his 1956 book as “professional policemen,... very mild Nazis”.[33]

Historian Christian Gerlach, writing about the 20 July conspirators and their complicity in war crimes of the Wehrmacht, refers to Nebe as a "notorious mass murderer". He discusses the role of Henning von Tresckow and his adjutant, Fabian von Schlabrendorff, who were members of the resistance and writes:

Schlabrendorff claimed that he and Tresckow had convinced themselves that "under the mask of the SS leader lurked a committed anti-Nazi..., who invented pretexts for sabotaging Hitler's murderous orders. We succeeded in saving the lives of many Russians. The Russian population often expressed their thanks to us". [...] According to Schlabrendorff, Tresckow personally brought Nebe to the army group [of conspirators]. Nothing was said about the 45,467 murder victims of Einsatzgruppe B by November 1941, the point at which Nebe returned to Berlin.[44]

Gerlach doubts that Nebe falsified Einsatzgruppe B reports to "sabotage Hitler's murderous orders". Gerlach puts Schlabrendorff's claims in the context of bomb plotters' memoirs and "existing discourse" on the opposition group within the high command of Army Group Center: "Especially with reference to the murder of the Jews, [it is said that] 'the SS' had deceived the officers by killing in secret, filing incomplete reports or none at all; if general staff offices protested, the SS threatened them. (...) This is, of course, nonsense."[45]

The historian Waitman Wade Beorn writes that "some have argued that [Nebe] deliberately inflated the numbers of Jews he reported killed. Yet all evidence indicates that he was quite content to play his role in Nazi genocide and that his subsequent displeasure with the regime may have stemmed from the imminent Nazi defeat but not opposition to the Holocaust".[46] Bernhard Wehner of the Kripo stated that Nebe was worried the Allies would punish him for his crimes, which was the only reason for joining the resistance.[12]
