There is a story, can’t find it now. Some of Pattons men freed a camp and were so enraged by what they saw, the machined gun down some captured NAZI officers. They were to be charged and brought to military court. Patton lost the paper work.
Yes that happened at a number of camps
One of the major camps maybe Dachau ..a young SS officer who had just arrived was given charge the day the camp fell when the culpable commander had already fled (later caught charged and hanged)
He tried to stop the killing of prisoners and surrendered the camp as peaceably as he could
He was executed that day anyway but line soldiers who grabbed
Bad luck for him or no good deed goes unpunished
Lots of reprisals not surprisingly
Frankly as bad as the camps were
Some of the most personal atrocities against Jews and others were in Ukraine and Lithuania and Croatia
And commited by civilians Rwanda style without firearms
Brutal stuff like pregnant women sliced open baby removed and bashed in front of her eyes
In a part of Ukraine contested by Poland Ukrainian nationalists under Bandera did this to polish ethnics
100,000 to 200,000
Eastern Europe is a vicious place Christian Comanches
Now Poland is Ukraine biggest supporter
Go figure
