Under the code name “Aktion 1005” the Germans tried to cover all tracks of Nazi extermination policy in the east, by opening mass graves and cremating hundreds of thousands of bodies.
The code name had its origin in the file number 1005, used in the related correspondence between Gestapo chief SS-Gruppenführer Heinrich Müller and Martin Luther, member of the foreign office. All units involved were given the name “Sonderkommando 1005” (special command 1005).
The action was planned in early 1942 for three reasons:
1. The Allies had obtained knowledge of German mass murder.
2. The rapidly buried victims of mass shootings and gassings became a health problem. In Chelmno, Auschwitz-Birkenau , the Aktion Reinhardt camps, and other killing sites (Einsatzgruppen) the bodies were buried in communal graves. Very quickly, the authorities questioned this method of disposing of the corpses. Near the two first gas chambers in Auschwitz-Birkenau (Bunkers I and II) the summer sun caused the corpses to swell. The surface burst open, and a black foul smelling substance appeared, contaminating the ground water. The horrible stench attracted millions of flies, and the whole region suffered as a consequence. The same happened at several other sites, since the summer of 1942 was extremely hot.
3. The Nazis thought that future generations might not understand the mass killings.
In March 1942, SS-Obergruppenführer Reinhard Heydrich placed SS-Standartenführer Paul Blobel in charge of the Aktion 1005. However its start was delayed after Heydrich was assassinated in June 1942 by Czechoslovakian SOE agents in Operation Anthropoid.
It was after the end of June that SS-Gruppenführer Heinrich Müller, head of the Gestapo finally gave Blobel his orders.
While the principal aim was to erase evidence of Jewish exterminations, the Aktion would also include non-Jewish victims of Nazi Einsatzgruppen.
Blobel began his work experimenting at Chełmno (Kulmhof). Attempts to use incendiary bombs to destroy exhumed bodies were unsuccessful as the weapons set fire to nearby forests. The most effective way was eventually found to be giant pyres on iron grills. The method involved building alternating layers of corpses and firewood on railway tracks. Afterwards remaining bone fragments could be crushed by pounding with heavy dowels or in a grinding machine and then re-buried in pits.The operation officially began at Sobibór extermination camp. The Leichenkommando exhumed the bodies from mass graves around the camp and then burned them, after which task the workers were executed. The process then moved to Bełżec in November 1942.The Auschwitz and Belsen camps had crematoria with furnace rooms on site to dispose of the bodies, therefore the Aktion 1005 commandos were not needed there.Surplus corpses were burned by their own prisoners.
The semi-industrial incineration of corpses at the Treblinka extermination camp began as soon as the political danger associated with the earlier burials was realized. In 1943, the 22,000 Polish victims of the Soviet Katyn massacre were discovered near Smolensk in Russia and reported to Adolf Hitler.Their remains were well preserved underground, attesting to the Soviet mass murder. By April 1943, the Nazi propaganda began to draw attention of the international community to this war crime. The Katyn Commission was formed to make detailed examinations in an effort to drive a wedge between the Allies.Meanwhile, the secret orders to exhume mass graves and burn the hundreds of thousands of victims instead came directly from the Nazi leadership in April.The corpses that had been buried at Treblinka with the use of a crawler excavator were dug up and cremated on the orders of Heinrich Himmler himself, who visited the camp in March 1943. The instructions to utilise rails as grates came from Scharführer Herbert Floss, the camp’s cremation expert. The bodies were placed on cremation pyres that were up to 30 metres (98 ft) long, with rails laid across the pits on concrete blocks.
They were splashed with petrol over wood, and burned in one massive blaze attended by roughly 300 prisoners who operated the pyres.In Bełżec, the round-the-clock operation lasted till March 1943. In Treblinka, it went on at full speed until the end of July.
The operation also returned to the scenes of earlier mass killings such as Babi Yar, Ponary, the Ninth Fort, as well as Bronna Góra. By 1944, with Soviet armies advancing, SS-Obergruppenführer Wilhelm Koppe,
head of the Reichsgau Wartheland ordered that each of the five districts of General Government territory set up its own Aktion 1005 commando to begin “cleaning” mass graves. The operations were not entirely successful as the advancing Soviet troops reached some of the sites before they could be cleared.
In his affadavit submitted at the Nuremberg Trials, SS-Hauptsturmführer Dieter Wisliceny, a deputy of Adolf Eichmann involved in the Final Solution,submitted the following testimony regarding Aktion 1005:
In November 1942, in Eichmann’s office in Berlin, I met Standartenfuehrer Plobel , who was leader of Kommando 1005, which was specially assigned to remove all traces of the final solution (extermination) of the Jewish problem by Einsatz Groups and all other executions. Kommando 1005 operated from at least autumn 1942 to September 1944 and was all this period subordinated to Eichmann. The mission was constituted after it first became apparent that Germany would not be able to hold all the territory occupied in the East and it was considered necessary to remove all traces of the criminal executions that had been committed. While in Berlin in November 1942, Plobel [sic] gave a lecture before Eichmann’s staff of specialists on the Jewish question from the occupied territories. He spoke of the special incinerators he had personally constructed for use in the work of Kommando 1005. It was their particular assignment to open the graves and remove and cremate the bodies of persons who had been previously executed. Kommando 1005 operated in Russia, Poland and through the Baltic area. I again saw Plobel [sic] in Hungary in 1944 and he stated to Eichmann in my presence that the mission of Kommando 1005 had been completed.
As a result of this operation many mass graves were obliterated, making it impossible after the war to ascertain the exact extent of the Nazi crimes, especially in the Soviet Union and Poland.
Blobel was sentenced to death by the U.S. Nuremberg Military Tribunal in the Einsatzgruppen Trial. He was hanged at Landsberg Prison on June 8, 1951. Nearly 60,000 deaths are attributable to Blobel though during testimony at Nuremberg he alleged he only killed between 10,000–15,000 people.
The prosecution at the trial of Adolf Eichmann in 1961 attempted to prove that Eichmann was Blobel’s superior,
but the court did not accept it. Blobel’s superior was in fact Heinrich Müller
