For those of us unaware, Mountain Jews are Jewish people who have lived in the North Caucasus for several centuries. They are a unique demographic, identifying neither as Ashkenazic nor Sephardic (though some have had Ashkenazic neighbors), and there are undoubtedly aspects of their culture that many of their Jewish siblings elsewhere would find odd.

When the anticommunists reinvaded Soviet Eurasia in 1941 and later made it to the North Caucasus, some of their victims were Mountain Jews:

[T]he [Axis’s] first encounter with Mountain Jews ended with the latter’s murder. This first massacre of Mountain Jews took place outside the borders of the North Caucasus, in the Shaumian Kolkhoz in the Crimea, most of whose members, it would seem, were Mountain Jews.⁴⁶

In March 1942 one of the Gentile neighbors informed the [Axis] authorities about the “Jewish presence” in the area. In response, Einsatzgruppe D—in cooperation with the military gendarmerie (Feldgendarmerie) and local collaborators—rounded up and murdered all 114 Mountain Jews there.⁴⁷ This was carried out in full cognizance of the fact that these were Mountain Jews, i.e., not Ashkenazi.⁴⁸

The Mountain Jews had been settled in the Crimea under the aegis of the American Jewish Joint Distribution Committee, whose aid the Soviet government accepted as part of a program to resettle Jews “on the land”; the [Axis powers] were aware of this, and it may have inclined Einsatzgruppe D to view the Mountain Jews there as participants in the same “world Jewish conspiracy” and therefore to kill them along with the Ashkenazi Jews.⁴⁹

It should be noted that the annihilation of Mountain Jews was mentioned only in a local military report,⁵⁰ but not in the more official Ereignismeldung (Situation Report) that Einsatzgruppe D sent to Berlin. Thus it may be that the Einsatzgruppe considered its decision to murder the Mountain Jews in the Crimea a local matter, and that they thought they did not need to obtain authorization from Berlin for such actions—either before or after

[…]

The first communities of Mountain Jews captured by the [Axis] in the Caucasus, at the end of August 1942, were two kolkhozes in Bogdanovka and Menzhinskoe (Kursk Raion, Stavropol Krai), in which the Mountain Jews constituted a significant portion of the entire Jewish membership.⁵⁷ Meanwhile, spontaneous incidents of looting Jewish property, brutalization of Jews, and murder multiplied rapidly.

There is no evidence that the [Axis] even considered treating the Mountain Jews here differently from their Ashkenazi co-religionists: perhaps the fact that they lived together caused the [Axis] to view them as a single entity. Scores of Mountain Jewish families who remained in Bogdanovka and Menzhinskoe were murdered by machine gun fire on September 20 and August 19, 1942, respectively,⁵⁸ a total of about 850 victims.⁵⁹

We do not know with certainty which [Axis] forces were responsible for exterminating the Jews in these two places. In theory, the kolkhozes were situated in the operative domain of Einsatzkommando (EK) 12. However, Soviet findings claim that a large Wehrmacht unit camped in Bogdanovka⁶⁰ and murdered the Jews there; this points to the possibility of the direct involvement of the [Wehrmacht]. This would increase the likelihood that the [Axis powers] (at least in Bogdanovka) were unaware of the Mountain Jews’ uniqueness.

Hence,

86. Both Altshuler and Arad estimate that about 1,000 Mountain Jews perished during the Holocaust. Altshuler, Yehudei mizrah Kavkaz, 151; Arad, History of the Holocaust in the Soviet Union, 2004, 535. However, this estimate does not take into account up to 1,400 Mountain Jews murdered in the village of Ganshtakovka (see n. 56). With this the death total reaches between 2,000 and 2,500, some forty to fifty percent of the original number in the region occupied by the [Axis].

(Emphasis added in all cases.)

If 2,500 seems like a ‘low’ number, your suspicion is justified by numerous factors, namely the Axis’s limited reach as well as its relatively brief presence where Mountain Jews lived:

The [Axis] advance had brought under occupation large sections of the North Caucasus, including Orzhonikidze (after liberation changed to Stavropol) and Krasnodar territories (krai, pl. kraia), the Kabardino-Balkar Autonomous Republic, and a large part of the North Ossetian Autonomous Republic, homes to a large portion of the Mountain Jew population. These found themselves under [Axis] occupation for varying periods of up to five months.

However, most of the large groups of Mountain Jews were in fact not overrun. Out of a Mountain Jewish population of 35,000 in the USSR on the eve of the Second World War,⁸ the only major centers that would be occupied were Nal’chik (capital of Kabardino-Balkaria, occupied for only two months) and Mozdok (in Ordzhonikidze Krai, occupied for four and a half months). In addition, Mountain Jews were a significant component of the local population in some small rural settlements.

Silly racial theories:

The [Axis] did not conclude decisively whether the groups were of Jewish origin. Two variants contradicted the possibility of common ancestry with European Jews: (a) the Mountain Jews originated in Persia after mixing with the Persians;³⁸ or (b) they derived from a mixture of several “Eastern races.”³⁹ […] The [Axis powers] were […] inclined to the opinion that these were not Jews at all because physically they did not have a Jewish “appearance,” and because they practiced polygamy.⁸⁰

Along with Soviet and partisan recruitment:

A factor reducing the number of Mountain Jews falling under [Axis] occupation was the induction of males between the ages of eighteen and forty (and in many cases older than that) into the Red Army and (to a much lesser extent) the partisan movement. Many testimonies¹⁰ document the enlistment of the men, since at this point—about a year into the war—the Soviet Union was maximizing the exploitation of its human resources to fight the war.¹¹

We can reasonably assume that a large percentage of the men of the community had been drafted before the [Axis] arrived.¹² Regarding participation in the partisan movement, we have only isolated examples and incomplete information allowing no basis for estimating the percentage of Jews who adopted this course.¹³

Taken together, these reasons explain why the Axis’s violence against Mountain Jews was surprisingly less awful than it could have been; the majority of Mountain Jews who had come under occupation survived thanks to the Axis’s uncertainty and hesitation. Even so, for some of us this is going to feel like an inadequate compensation; two thousand deaths is still deeply upsetting.

Ashurova recalled how the Ifraimov family of Mountain Jews paid with their lives for an unsuccessful attempt to rescue a family of Ashkenazi Jews: “Our Mountain Jews hid two sisters who were physicians… [The Axis] executed both sisters with the Mountain Jews who were hiding them. Twelve souls [were killed] instantly.”⁴²
