Another comment from someone else. This might be a topic well worth looking into. Take note the Germans were described as "very decent people":-

There were LOTS of P.O.W. camps full of Germans…all over America. Some very interesting stories about it all. Books were written about it all. You just have to do a few quick searches and it all comes up. The reason you don’t see much about it….. The people that were watching over them/guarding them, tended to describe them as VERY DECENT PEOPLE.
