There's an excellent site on You Tube called “Critical Past’’. It's US Army Signal Corps footage from various locations that was filmed in Germany in the closing months of the war.
There is one video of the liberation of Dachau, complete with scenes of that long line of train cars, some of them open Gondola cars filled with dozens of poor souls who either froze to death or died of disease or wounds.
In one scene there is an American soldier with a .45 in his hand herding four SS men, the one's you describe towards a box car and then the film cuts out.
Good for the SS bastards.
No SS trooper, Waffen SS or the “Totenkopf’’, they one's who ran the camps should have ever been taken alive.
The SS was a criminal organization that fought deliberately and purposefully outside any known rules of warfare. The SS guards at Dachau and else knew they were dead meat when the were caught. The Russians routinely shot them. In fact the Russians pretty much shot every German they got a hold of.
And then the Russkies turned around and made Buchenwald into an NKVD-run Camp.
