There were reports of "take no prisoners" orders at the squad level in the area after Malmedy to American soldiers in retaliation. As well as individual acts of retaliation against SS prisoners/those trying to surrender.”
Hum, you can’t compare as you stated “individual act of retaliation” and systematic slaughter of war prisoners like the SS started from the beginning of the war (Dunkirk against the English, Gamblou against the French).
However, I find the mistake quite funny…
