:::Gosh, if you want to add a comparison, go ahead and do it! I'm not stopping you. I never said it was wrong to add a comparison.

Here is a featured article about a Candide that uses the Further reading section just the way it is used here. Actually, there are two books in that section. There are also a few relevant academic articles and all the remaining relevant reviews that were published in English.

About the Einsaztgruppen, you should go back to the wiki article you tried to use against me and read it again. Nowhere it says that they were under orders of the Wehrmacht, but that they were in close cooperation. I'll quote it for you: Each Einsatzgruppe was led by SD, Gestapo and Kripo officers, and its members included recruits from the Orpo, the Waffen-SS, and local volunteers, such as militia groups. Each death squad followed the Wehrmacht Heer (German Army) as it advanced eastwards through Eastern Europe and the Soviet Union. During the course of their operations, the Einsatzgruppen commanders were authorized to request, and did receive, assistance from the Wehrmacht. Heydrich acted under orders from Reichsführer Heinrich Himmler who supplied security forces on an "as needed" basis to the local SS and Police Leaders. They were different organizations. The Wehrmacht could not give order to the SS. Again, from that article: The Einsatzgruppen were formed under the direction of SS-Obergruppenführer Reinhard Heydrich (deputy to Heinrich Himmler) and operated by the Schutzstaffel (SS) before and during World War II. From September 1939 forward the SS-Reichssicherheitshauptamt (RSHA – Reich Main Security Office)[4] had overall command of the Einsatzgruppen.

What Littell does is to make the picture unclear by saying that the Wehrmacht worked too closely with the Einsaztgruppen. The following passage is singular in that respect: “I don’t understand. Who should we take our orders from, in the end? From Reichenau or Jeckeln? And where is Brigadeführer Rasch?”—“I don’t know, Sturmbannführer.”. I suggest changing "attached" to "worked closely with", "cooperated" or something like that.

As for the sentence the Sixth Army, the AOK 6, to which we were attached, Littell originally used the verb "rattacher", auquel nous étions rattachés, which is usually translated as "linked", "connected" or "associated". By translating it to "attached", it took away the double entendre in Littell original text.

Unfortunately, we'll have to disagree about the image.
