This episodes claims there was a lot of opposition to the KLV program (Kind Land verschikung ) or Child evacuation.
The reason is that the state saw kids as kids of the fuhrer and as a tool. Willy Langbein (b1930) his time was eaten up by the HitlerJugend and indoctrination.
Because he and his parents lived in the industrial Ruhr area he was evacuated to the sticks where his HitlerJugend militaristic “education” continued.
He ended up as a Child Soldier defending “Vienna” sitting in a foxhole with a Panzerfaust and rifle. He did survive but his memoires are creepy but valuable.
We know the HitlerJugend tried to keep the kids away from other social circles such as critical churches or non-Aryans. This was a tool of indoctrination.
To expand on the question, did the Nazi Government deliberately evacuate the kids to turn them into child soldiers by having complete control over the kids send them to Russia without “pesky (well brave) parents” disagreeing?
