I don't know and don't care about what has been said by those who were not even born back then.I have read about the "sanitizing" of the Wehrmacht after the war. It was a politically expedient. The Wehrmacht was also ordered to, and did, carry out large scale atrocities.
There are many ways to find the truth... I personally like the more savage ways... A blade, ready to cut their dear's throat, will loose their tongues. Easy, and extremely effective to root out any and all false / wrong info's.
