Great find, Six Gun.
There actually are at least three men with the X-cross on their jackets, as can be seen in these three snaps about half a second apart each:
And it seems pretty clear that the scene is indeed Dachau, as can be confirmed at the furtherglory blog
All of which raises any number of interesting questions.
For example, if the stripes and crosses were indeed meant to indentify members of the so-called Sonderkommandos, what were SK members doing at Dachau? (No gassings in Dachau, right Dr. Broszat?
Or could they have been transferred from other camps (e.g., Auschwitz) at the end of war? Maybe. But then, consider the image of those three men walking casually through the crowd of prisoners in the camp. If the stories of mass gassings--and thus, SK complicity in them--were true, every single person in that scene would have known it. (I think we can assume that prison gossip would have worked as well in the KZ system as anywhere else.) And yet, the three men appear entirely unconcerned moving through the crowd, and the crowd in turn appears to take no particular notice of them. As if to say, Collaborated with the Nazis to murder your fellow prisoners by the thousand? No problem!
Just how likely is that?
No, those guys would have been marked men, and not just because of the crosses on their backs. And you can be sure they'd have done everything they could to get rid of those crosses as soon as the Nazis (and thus, their collaborator-protectors) were gone. They certainly wouldn't have been strolling around the prison yard wearing them.
Hmm, I wonder . . . Could it be that the reason no one is paying any particular attention to the SK men here is just that everyone knew who they were and what they did, and that there was nothing particularly sinister about the matter? That the famous Sonderkommandos really were nothing more and nothing less than the crematorium work detail, guys selected to do an unpleasant but necessary job if public health were to be maintained in the camps in the face of high mortality from disease? Undertakers, in other words, but not murderers--or even murderers' assistants. Just three guys with a job to do?
