The US has admitted that for a time after the Nazis massacred 80 US pows at Malmedy any Germans taken prisoner were at a greater risk of being harmed due to the anger the GIs felt over what happened at Malmedy. But as far as what happened at Chenogne the stories vary so much about the facts it is not believed by many. Doesn't matter, winners don't apologize anyway that would dull the win. War is hell.
