On the night of September 29, 1943, exactly two years after the largest single massacre of the Holocaust, chained prisoners deep inside the ravine at Babi Yar made a desperate bid for freedom. They had spent six weeks digging up tens of thousands of rotting corpses and burning them on giant pyres, all under the watch of machine guns. Their task was nearly complete, and they knew what came next. The SS intended to kill them and burn their bodies with the rest.
Most of the prisoners died in the escape attempt, but a small group of about fifteen to twenty broke through into the darkness. Their survival was a miracle. Their testimony would become one of the only firsthand accounts of the most secret operation of the Nazi regime, an operation designed to erase the evidence of genocide itself. The man responsible for that operation was Paul Blobel.
He was not born a monster. Born in Potsdam, Germany, in 1894 to a Protestant family, he served as an artilleryman in the First World War and earned the Iron Cross First Class. After the war, he studied architecture and ran his own practice starting in 1924. But the Great Depression wiped out his livelihood, and in that time of national shame and personal ruin, he joined the Nazi Party in 1931 and later the SS.
By 1934 he was working for the SD, the SS intelligence agency, and eventually led its office in Düsseldorf. He was an organizer, a bureaucrat who saw his job as executing orders efficiently. That skill would soon be put to terrible use. When Germany invaded the Soviet Union in June 1941, four special mobile killing units known as Einsatzgruppen followed the regular army.
Their official purpose was to eliminate political enemies. Their real secret order was to murder the Jewish population of Eastern Europe. This became known as the Holocaust by bullets, a wave of mass shootings that claimed over one and a half million lives. Blobel, now an SS Standartenführer, equivalent to a full colonel, was given command of Sonderkommando 4a, part of Einsatzgruppe C, and sent to Ukraine.
His unit was brutally efficient. In towns like Lutsk and Zhytomyr, they rounded up and shot thousands of Jewish men, women, and children, often with help from local collaborators. In Zhytomyr in August 1941, Blobel organized the murder of about three thousand Jews. A witness later described a killing of children at Bila Tserkva.
The children were taken from a tractor, lined up along the top of an open grave, and shot so that they tumbled into it. The wailing, the witness said, was indescribable. Blobel was there, watching over everything. His drinking, already heavy, grew worse as the killings he ordered grew larger.
But bullets were not his only tool. In late 1941, gas vans appeared. These were sealed trucks whose exhaust pipes pumped carbon monoxide into the sealed cargo compartments, killing the victims slowly and painfully. This was the man Blobel had become, an organizer of mass death, responsible for the murder of tens of thousands.
His most infamous act, however, was still ahead. In late September 1941, the German Sixth Army captured Kiev, capital of Soviet Ukraine. Days later, mines planted by the retreating Red Army detonated in the city center, destroying German headquarters and killing German soldiers. For the Nazi command, this was the perfect pretext.
They publicly blamed the city’s Jewish population and ordered the annihilation of every Jew in Kiev. The task fell to Blobel and his Sonderkommando 4a. On September 28, notices posted throughout the city ordered all Jews to assemble the next morning near the Lukyanivka cemetery. They were told to bring documents, money, and warm clothing for resettlement.
Fearing deportation but not suspecting the truth, tens of thousands obeyed. At the assembly point, they were forced to hand over their valuables and strip naked. Ukrainian auxiliary police and SS soldiers herded them forward to the edge of Babi Yar, a deep natural ravine on the city’s outskirts. Victims were led in small groups to the precipice, where layers of the dead already lay.
They were forced to lie face down on the bodies of their neighbors and family members before being shot in the back of the neck. A truck driver who witnessed the scene later described how the marksman would walk across the bodies of the executed to the next Jew, who had meanwhile lain down, and shoot him. The wounded were left to die among the dead, and German soldiers periodically collapsed the sandy walls of the ravine to bury the living and the dead together. Over just two days, September 29 and 30, 1941, Blobel’s unit and its support forces murdered 33,771 Jewish men, women, and children.
The figure comes directly from the Einsatzgruppe’s own chillingly bureaucratic report. It was the largest single massacre of the Holocaust, and Blobel oversaw it personally. But the psychological toll of orchestrating such carnage, combined with his chronic alcoholism, broke him. On January 13, 1942, he was officially dismissed from his command for health reasons.
For most officers, that would have ended their career. But the Nazi leadership had a different plan for Paul Blobel. His intimate knowledge of mass murder made him uniquely qualified for an even more secret task. By the spring of 1942, the war had turned.
The German advance into the Soviet Union had stalled, and the United States had joined the fight. The Nazi leadership faced a terrifying problem: the evidence. Thousands of mass graves stretched across Ukraine, Belarus, and the Baltic states. The killings had often happened in the open, and news was reaching the Allies.
Worse, in many places, shallow graves swelled and burst open in the summer heat, poisoning the air and groundwater. The dead refused to stay buried. Reinhard Heydrich first gave Blobel the job in March 1942. After Heydrich was assassinated, the head of the Gestapo, Heinrich Müller, issued the final order.
It was given only verbally and assigned a codename from its file number: Sonderaktion 1005. Its goal was simple and monstrous. Find every mass grave in the east. Dig up the bodies and destroy them so completely that no trace would ever be found.
It was a plan to erase the Holocaust from history after the fact. Blobel approached the problem with the cold logic of an architect. Simple burning in the pits would not work. He needed to test methods.
His first test site was the Chełmno extermination camp, where in June 1942 he tried incendiary bombs, but those set the nearby forests on fire. Explosives simply blew the bodies apart. Finally, he developed what became known as the Blobel pyre. A massive grill was built over a dug-out grave using railway tracks on concrete blocks.
Layers of bodies and wood were stacked high, doused with gasoline, and ignited. These fires could burn for days, consuming the bodies almost completely. Afterward, any remaining bone fragments were crushed to powder in special bone-crushing machines. The ash was scattered or reburied, and the ground was smoothed over and often replanted with trees.
The final cruelty involved the workers. The SS men of Sonderkommando 1005 would not do this work themselves. Instead, prisoners, nearly all of them Jewish, were forced into what were called Leichenkommandos, corpse commandos. Chained to prevent escape, they dug into the rotting graves, pulled out the decaying bodies of their own people, fed them to the fires, and operated the bone grinders, knowing that once their work was finished, they too would be killed and burned.
With his method perfected, Blobel sent his units across the killing fields of Eastern Europe. In Ukraine, he formed Sonderkommando 1005a and 1005b. Another unit worked near Minsk. Each group consisted of SD officers, German police guards, and the chained prisoners.
At the Yanovska camp, a prisoner named Leon Wells survived to describe the daily horror. Chained at the ankles, prisoners marched to killing sites to perform a three-part task. Diggers opened the mass graves. Haulers pulled out the tangled bodies and checked their mouths for gold teeth.
Burners stacked the corpses on the fires, watched them, and operated the crushing machines. Anyone who was too slow or broke down was shot immediately and thrown onto the fire. The operation spread through Poland, Ukraine, Belarus, and the Baltic states. Near Riga, Blobel oversaw the burning himself.
At Maly Trostenets near Minsk, his units dug up and burned tens of thousands of bodies. But no site carried more symbolic weight than Babi Yar. In August 1943, Sonderkommando 1005a returned to the ravine outside Kiev. Blobel, the man who had ordered the massacre there less than two years earlier, now returned to order the burning.
In a cold, emotionless statement at Nuremberg, he described what he saw. The bodies were covered with flammable material and ignited. It took about two days for the grave to burn down to the bottom. Then it was filled in, and the traces were practically obliterated.
He did not mention the 327 prisoners forced to do the work. They labored for over six weeks, chained and guarded by machine guns, burning what historians estimate were at least seventy thousand bodies from the various massacres at the site. They knew what awaited them. On the night of September 29, 1943, the second anniversary of the massacre, they revolted.
Most were killed, but a small group escaped. Their stories became one of the only firsthand accounts of Sonderaktion 1005. From the summer of 1942 through mid-1944, the operation worked without rest, burning bodies at Bełżec, Sobibór, and Treblinka, and moving across the occupied east. It was a continent-wide effort to rewrite history by burning it.
But history is not so easily erased. The Soviet advance was unstoppable, and the operation simply ran out of time. In his Nuremberg statement, Blobel admitted the failure. It was not possible, he said, to destroy the graves farther south and east because the front line was advancing.
Soviet reconnaissance planes flew over areas where the great fires still burned. Advancing soldiers found graves only partially dug open, abandoned bone-crushing machines, and the black remnants of the pyres. The Soviet Extraordinary State Commission began documenting the crimes, interviewing local witnesses and the few survivors of the Sonderkommando revolts. At Babi Yar and elsewhere, they dug up bodies themselves, finding that even with Blobel’s best efforts, the evidence had not been completely wiped away.
The earth itself remembered. As the German war effort collapsed, the Sonderkommando 1005 units were broken up. Paul Blobel was captured by Allied soldiers. He was tried at Nuremberg, not in the famous International Military Tribunal, but in the United States military’s Einsatzgruppen trial, where twenty-four former commanders of the mobile killing squads faced charges of war crimes and crimes against humanity.
The trial began on September 29, 1947, six years to the day after he started the Babi Yar massacre. Blobel pleaded not guilty, offering a defense of denial and claiming he was only following orders. While the prosecution held him responsible for at least sixty thousand deaths, Blobel claimed he had killed only ten to fifteen thousand, as if that number could prove his innocence. The evidence was overwhelming.
The prosecution produced the Nazis’ own detailed reports, Blobel’s own cold statement describing Sonderaktion 1005, and the testimony of survivors. He was found guilty on all three charges. On April 10, 1948, he was sentenced to death by hanging. Blobel spent three years on death row at Landsberg Prison.
In the early morning of June 7, 1951, Paul Blobel was hanged. The architect of mass murder and the man who tried to burn the memory of his crimes from the world was executed. Sonderaktion 1005 was the Nazi regime’s final proof that it knew it was guilty. It was a confession made with fire and ash, a desperate attempt to hide a crime too vast to hide.
Having murdered millions, the regime’s last act was an attempt to kill the truth itself. It failed. It failed because a handful of chained prisoners fought back at Babi Yar and escaped to tell their story. It failed because advancing armies found the half-erased evidence.
And it failed because the records the Nazis created themselves, their own reports, their own statements, and the scarred land of Eastern Europe, were too enormous to destroy. The ashes Blobel’s commandos scattered could not stop the story of the dead from being told. History has a way of not going away, even if you try to bury it or burn it. The attempt to erase the Holocaust was its last crime, and it failed.
The evidence survived, and in the end, however incomplete, justice had the final word.
