If you look at the first German POW up close he’s smiling for the photo op. Probably tryed his best to befriend as many Allies as he could so he didn’t get shot!
My grandfather told me, that of all the people he encountered during WW2 it was the Germans that he liked best.
It reminds me of that scene in Saving Private Ryan where they decided to let that German solider go because he was pleading for his life and being friendly etc. Then the bastard found another troop division and killed one of the Americans… I’m sure things like that happend…
