Rape by Red army soldiers is a well-known fact. However, rape by soldiers of other countries that fought against Germany isn’t widely discussed.
Miriam Gebhardt in her book “When the soldiers came” claims that the US soldiers raped up to 190,000 soldiers. How authentic and truthful is this information? If not what are the estimated numbers?
I found an article that explains how the author came to the conclusion that 190,000 women were raped by American soldiers. She assumes that 5% of "war children" born to unmarried mothers with American fathers in West Germany and West Berlin up to the 1950's (yes, 5+ years after the war ended) were the product of rape (a total of 1,900), and then further makes the assumption that there were 100 rapes for every birth, bringing us to the cited total of 190,000 rapes.
In other words, she basically pulled the statistic out of her behind. Reaching her conclusion requires assumption on top of assumption on top of assumption. Not exactly the basis for a sound historical argument.
Did allied soldiers (of all nations) engage in rape? Absolutely. Were women of conquered nations coerced by circumstance into sexual acts that were less than consensual? Of course. Did American soldiers act dishonorably at times? Undoubtedly.
Here's a different source that places the number of rapes committed by American soldiers against French civilians from D-Day to the end of the war at 2,500, and another [source](https://en.wikipedia.org/wiki/Taken_by_Force_(book) that places the number at around 11,000 rapes in Germany. Unpleasant, of course, but frankly not even close to what Gebhardt claims. While it's true that American soldiers had more reason to treat German civilians in a harsher manner than they did French civilians, they would have had to act almost 100 times more viciously in Germany than they did in France for Gebhardt's argument to hold water, and there's simply no evidence to support that.
Add to that the fact that American forces generally took war crime allegations seriously, and indeed had some strict regulations regarding any sort of fraternization with German civilians, and it becomes clear that Gebhardt appears to be more interested in selling copies of her book, rather than responsibly presenting her historical findings.
On a sidenote, if you're interested in an actually scandalous statistic on the topic, check out the rate that African American soldiers were prosecuted for rape compared to white soldiers.
