Yep! It's a little-known footnote in history. I found out about it as a child in listening to stories of DPs who made it to the USA. Many of them were upset/angry/outraged but afraid to say anything "officially" for fear of being returned to DP camps now full of the "ethnic Germans" that had replaced them.
Two notes, for the irony factor - none of the second-round deportees were tattooed, and we (The Allies) had dismantled and shipped back home the data-storage machines that used to keep tabs on not only how many went into the camps and "left" but specifically who that was, so the second-round folks "disappeared". Figuring out who "we" did that to is thus next to impossible.
When I got older I was amazed to realize that the victims of The Holocaust were not, for the most part, celebrating what was happening to folks who might have been among those supporting/agreeing with the Final Solution. The resiliancy of the human soul is truely awesome.
Fistful -
Agreed that some of the 500,000 deaths were not directly attibutable to the enforced relocation. Allow me to ask you your thoughts on deaths of the losing side in general, be it European (pick your century), Asian, Australian, African (northern, Saharan, or sub-Saharan), or American (both above and below the Rio Grande). [Sorry, it's a very sore point.]
stay safe.
