I’ve read of, and don’t ask where because I forgot, Allied POW camps in America and England, where the prisoners were treated most excellently.
The British would use volunteer German POWs to help farmers and the farmers would respond by feeding the prisoners with great portions of farm cooking that they loved and escapes were low. Probably because of the good way they were treated.
In the States, the POW camp was in the Midwest, on the edge of a desert and not only were the POWs treated well, but occasionally allowed to go into the nearest town for R&R, to take in a movie or have a malted. There was only 1 escape attempt and the Americans did not make a big thing out of it because the desert was nothing like anything the Germans were used to. Three escaped, two returned after a few days of broiling during the day and freezing at night and the last held out nearly two weeks before he got tired of nearly starving and turned himself in.
I have heard that the Japanese Prisoners were treated with dignity, something they did not do for allied POWs, but do not recall where their camps were.
I think Canada had a POW camp and Australia had one.
I read how German, Italian, French and Japanese POWs expected to be treated like dirt, because that’s pretty much how they treated prisoners, but were surprised at how well they were cared for and fed. Especially towards the end of the war, when most of them were running on low rations. They found plenty of food awaiting them in the POW camps, which I think contributed heavily to low levels of escape attempts.
The Germans treated the Jews differently from everyone else, wiping them out as fast as possible, while solders placed in POW camps were treated quite a bit better. The Japanese considered everyone captured as a coward and inferior, because they, themselves, considered it abhorrent to surrender, and treated POWs like animals and slaves, killing many before they even got to containment camps and brutally abusing and killing even more when they arrived.
If you read the Heriot books, (All things Bright and Beautiful) about the English Vet, who just died not too long ago, he describes how the German POWs were used on farms, along with Italian and French prisoners. (Absolutely wonderful and great writer! From his works, he had to have been a prince among men! I was sad to find out that he passed on.)
