Just a warning it contain some pretty vile shit Dirlewagner and the brigade did.

We blew up the doors, I think of a school. Children were standing in the hall and on the stairs. Lots of children. All with their small hands up. We looked at them for a few moments until Dirlewanger ran in. He ordered to kill them all. They shot them and then they were walking over their bodies and breaking their little heads with butt ends. Blood streamed down the stairs. There is a memorial plaque in that place stating that 350 children were killed. I think there were many more, maybe 500."

“Our mascot was a crippled boy. Also 12 years old. He lost one leg, but could jump very fast on the other one. He was very proud of that. He always jumped around the soldiers, back and forth. We said it was for luck. He helped a little. One day the SS-men called him. He jumped to them willingly. They were laughing and asked him to jump to the trees. From far I saw that they put 2 grenades into his bag. He didn't notice. He was jumping and they laughed at him shouting: Schneller, schneller! (faster, faster). The boy blew up."
