You state that the battalion was formed from a 'penal unit' ( Bewahrungs-Soldaten). This is NOT a penal unit but a DISCIPLINARY unit. The Dirlewanger division was formed with elements of penal units,(Murderers, rapists, theives and deserters).
Bewahrungs-soldaten were merely disciplinary cases,(Late for guard duty, asleep on guard duty, listening to the BBC home service etc.) that were frowned upon by the draconian SS rules.
It should also be pointed out that some of the troops in the battalion were W-SS VOLUNTEERS, not drafted serious criminals as you describe with the word 'penal' or as behwarungs-soldaten, which are mere 'defaulters' in my book.
I'm sure that if any survivors of this battalion are still out there alive they will not be happy with you description of them as a 'penal battalion', and that is why i stand by my previous post.
