Einsatzgruppe

See also: Einsatzgruppen Case (NMT)

In general German military terminology, an Einsatzgruppe (plural Einsatzgruppen) is a temporary unit for a specific purpose, comparable to the English task force. Within the context of the Second World War and the Holocaust, they were mobile killing units that followed the armies, ostensibly for rear area security and principally for killing Jews, Soviet officials, and other Nazi undesirables. The term came into common use in the context of the Operation Barbarossa invading the Soviet Union, but the function started with the invasion of Poland, killing political undesirables and possible threats. The largest execution in the Polish campaign was perpetrated by Russians, not Germans, at the Katyn Forest.

The genocidal groups, which killed approximately 2 million people, were organized as part of the preparation for Operation Barbarossa. They all reported to the then head of the SS security organization, the RSHA, commanded by Reinhard Heydrich. His first instructions to them were issued Note that the actual invasion of the Soviet Union began on 22 June 1941.

Personnel were drawn from a variety of RSHA personnel, including the Waffen SS, ORPO (regular police), SD, Gestapo and KRIPO (criminal police), as well as local police and foreign auxiliaries. While regular military units were not directly assigned to the RSHAgroups, Army commanders were concerned they were brutalizing troops. On 6 February 1940, Gen. Johannes Blaskowitz, chief of the Army in Poland, complained

It is wholly misguided to slaughter some 10,000 Jews and Poles, as it is happening at the moment; such methods will eradicate neither Polish nationalism not the Jews from the mass of the population.

Leaders were tried in the Einsatzgruppen Case of the Nuremberg Military Tribunal, with most being executed or imprisoned.

Organization

There were four main battalion-sized groups, and some smaller independent Einsatzkommandos.

Group	Commander(s)	Attached to and strength	Area of operations
A	Franz Walter Stahlecker	Army Group North 990 men	From East Prussia across Lithuania, Latvia, and Estonia toward Leningrad (now St. Petersburg); Kovno, Riga, and Vilna.
B	Artur Nebe	Army Group Centre 665 men	From Warsaw across Belorussia toward Smolensk and Minsk, massacring Jews in Grodno, Minsk, Brest-Litovsk, Slonim, Gomel, and Mogilev, among other places.
C	Otto Rasch	Army Group South' 700 men	began operations from Krakow (Cracow) and fanned out across the western Ukraine toward Kharkov and Rostov-on-Don. Its personnel directed massacres in Lvov, Tarnopol, Zolochev, Kremenets, Kharkov, Zhitomir, and Kiev, where famously in two days in late September 1941 units of Einsatzgruppe detachment 4a massacred 33,771 Kiev Jews in the ravine at Babi Yar.
D	Otto Ohlendorf	11th Army 600 men	southern Ukraine and the Crimea, especially in Nikolayev, Kherson, Simferopol, Sevastopol, Feodosiya, and in the Krasnodar region.

Operations

Their primary means of killing was by shooting and burial in mass graves. Different commanders had different ideas on the method of shooting; some insisted on machine guns so no individual had clear responsibility for killing, while others insisted that every unit member shoot at individual victims, to bond them to the effort. With either method, there was a high degree of stress on the units, with rampant alcoholism, mental breakdowns and suicide.

After Erich von Bach-Zelewski had witnessed an execution with Himmler, he said tohim

Look at the eyes of the men in this Kommando, how deeply shaken they are! These men are finished [fertig] for the rest of their lives. What kind of followers are training here? Either neurotics or savages!

Hoess and Adolf Eichmann worked to find an alternative, less stressful killing method, assuming it would be a gas. By November 1942, however, they had not found one, and had not even considered methods for disposing of large numbers of bodies.
