The way they mopped up? Every time they came upon a body they would kick it, if there was no reaction they would move on, if there was a reaction they would shoot the wounded soldier immediately.
And why do you think this was limited to the Germans?
You see this is the essential problem with your stance. You are viewing the subject through "good guys/bad guys" eyes and that will ALWAYS lead to a false perspective. Everything the Germans will do is "bad" and anything the Allies do can be explained away.
Its just not good enough.
The major block in discussing these issues is that from the very outset, we aren't given all the transparent facts. For a start its very difficult to research Allied warcrimes with any certainty and frankly when one presents such a case, there is usually a pack of hounds ready to leap on it and kick up a stink to the point where a rational discussion on the subject becomes impossible for everyone concerned.
The accusation (and blind acceptance) of German warcrimes has become so commonplace, that almost anything can be claimed, with the absolute minimum of evidence and there will be a large number of people just willing to believe it, without any regard or pause for judgement.
This imbalance destroys any logical discussion on the subject.
All sides commited war crimes, just because the crimes of the side that lost are written about more frequently (by the side that won, on the whole) doesn't mean that one side has the monoply or the moral high ground.
Every side has the share of atrocity stories and like Dan I have heard quite a few. My own father used transfered to the RAF transport corps from the R Engineers at the end of the war. He used to ferry pilots to and from areodromes and some of the stories the pilots used to tell him gave him a vastly different perspective on the Allies and war crimes in general.
The problem is is that atrocities against the Germans are not written down, while any old warcrime/alegation/atrocity that the Germans are said to have committed are usually to be found in a book or some other situation. This certainly doesn't mean they constitute fact....anyone can make an alegation. And I have lost count how many times a standard alegation an be broken down with a little investigation into it.
