Here is a thorough demolition of the ridiculous claim that Ike ran death camps for German POW after WWII. The source of this fantastic lie was a 1989 book titled "Other Losses" by a Canadian novelist named James Bacque.

 Note that this article, published in the NYT Review of Books, is by Stephen Ambrose, who, at the time was America's most celebrated historian of WWII and that it relays the findings of a 1991 scholarly conference convened to examine the claims in Bacque's book.

The overall conclusion is that it was "worse than worthless". This is the sort of source one finds when when looks closely at the claims of  Holocaust deniers and apologists for white nationalism like AGirlWho etc. here:  a fanatical misapprehension of reality supported by obscure, badly researched and biased analyses, when not made outright from whole cloth. 

It's a good thing that evil people now seem to be so stupid . . .
