Jean Bernard said this quote

On Good Friday last year the SS found some pretext to punish 60 priests with an hour on the tree. That is the mildest camp punishment. They tie a man's hands together behind his back, palms facing out and fingers pointing backward. Then they turn his hands inwards, tie a chain around his wrists and hoist him up by it. His own wight twists his joints and pulls them apart...Several of the priest who were hung up last year never recovered and died. If you don't have a strong heart, you don't survive it. Many have a permanently crippled hand.
