he does seem as you put it a grumpy old bugger so I assume his attitude has not helped. everything I've seen from him has been based on his word is gospel which is going to provoke reactions

I've not read it all but the bader story in there is a few lines, I assume his website had a lot more with his theories on why. it does seem that the dates and contemporary events seem confused. he also talks of the man having two sticks which contradicts all the descriptions of baders ability to walk, even if one accepts he might have had something temporary - however the german description of walking well without a stick is from his attempted escape just prior to his spell in lamsdorf solitary so the two descriptions don't seem to fit together. I'm still struggling to see any basis for his story having any way of fitting in with what's known of bader and the facts we have. the more I read the more I think he's got something badly wrong
