In this secret directive (telex dated 25 October 1942), SS-Obersturmbannführer Arthur Liebehenschel instructed SS-Hauptsturmführer Hans Aumeier that any inspection of the Auschwitz camp’s “special installations” for “special accommodation” (Sonderunterbringung) was strictly prohibited, and that “escape shootings” were to be avoided during the visit of a French construction commission inspecting the labor facilities of the Auschwitz complex.

1943-04-19 / The Short Version of the Korherr Report: “European Jewry has probably lost almost half of its total population”

On April 19, 1943, SS statistician Richard Korherr submitted a shortened version of his Korherr Report – the SS’s statistical account of the “Final Solution of the European Jewish Question” – to the personal staff of Reichsführer-SS Heinrich Himmler, for presentation to Adolf Hitler. In the report, Korherr estimated that “the reduction of Jewry in Europe from 1937 to the beginning of 1943 is to be estimated at 4½ million” and noted that “only part of the deaths of Soviet-Russian Jews in the occupied eastern territories could be recorded, while those in the rest of European Russia and at the front are not included at all.” He concluded that “European Jewry since 1933 has probably lost almost half of its total population,” of which “only about half has flowed to other continents.”

1943-07-20 / “A Germany of Kant and Goethe” – Gauleiter Kube’s Clash with the SS over the Killings of Jews in Minsk

On July 20, 1943, SS-Obersturmbannführer Eduard Strauch, Commander of the Security Police and the SD in White Ruthenia, issued a memorandum on a confrontation with Gauleiter Wilhelm Kube after Strauch had that morning “delivered for special treatment” (Sonderbehandlung) the entire Jewish staff of the General Commissariat in Minsk – an euphemism for their execution. Kube condemned the actions of the Security Police as “unworthy of a German human being and of a Germany of Kant and Goethe” and accused Strauch’s “men derived a kind of perverse pleasure from these executions”. Strauch, in turn, complained that “even the fact that the Jews who were to undergo special treatment had their gold dental fillings properly removed by medical specialists had become the subject of gossip”.

1943-04-10 / Himmler’s Order to Sanitize the Korherr Report: “At No Point Should There Be Any Mention of Special Treatment of the Jews”

In April 1943, Heinrich Himmler ordered changes to the Korherr Report, the SS’s statistical account of the “Final Solution” he considered as quite good “for camouflage purposes”. A letter dated April 19, 1943 instructed that the term “special treatment of the Jews” be removed from the report. The euphemism “passed through the camps in the General Government and the camps in the Warthegau” was to be used to denote the death toll from the extermination camps at Bełżec, Treblinka, Sobibór, and Kulmhof (Chełmno).

1943-04-09 / Himmler’s April 1943 Letter on the Korherr Report

A brief letter written by Heinrich Himmler, Reichsführer-SS, on April 9, 1943, to Ernst Kaltenbrunner, Chief of the Security Police and SD, makes direct reference to the so-called Korherr Report – a statistical analysis compiled by Richard Korherr, the SS’s chief statistician, on the progress of the “Final Solution”. In it, Himmler acknowledges the report’s value as “material for possible later times” and, above all, “for camouflage purposes”. At the same time, he orders that the report must not be published or circulated further. Himmler closes the letter by stressing his overriding concern that “what remains most important to me is that Jews are now being shipped off to the East as much as is at all humanly possible.”

1944-02-09 Report About Nazi Extermination Methods: Insights From an SD Defector

In February 1944, Swiss intelligence received one 106-page report by a defector (agent code D 143) from Nazi Germany’s Sicherheitsdienst (SD), the SS’s intelligence branch. Dated 9 February 1944, this report offers an insider’s view of the internal disintegration, moral collapse, and infighting that plagued the Nazi foreign intelligence service, known as Amt VI. The SD defector described various Nazis’ extermination methods, experiments, and plans. He reveals that the commandos in the East adopted “the GPU method of a shot to the back of the neck” which was “widely used” with “in total, up to 100,000” victims. He also described the use of homicidal gas vans, known as “Nebe gas vans” after Arthur Nebe, the former head of Einsatzgruppe B and chief of the Criminal Technical Institute. According to the report: “rear compartment was sealed; 20 cm thick oak walls lined with sheet metal. Engine in front, from where exhaust gases are directed into the interior of the truck through a pipe.” The SD man noted that within Einsatzkommandos, most personnel were “completely drunk,” with as many as 40% suffering nervous breakdowns. He recalled that in in Summer 1943, Einsatzgruppe C chief Max Thomas informed him that “that approximately 6,000,000 people (Russians and Jews) had been disposed of”.
