We know that when many German soldiers were captured by Americans, they were herded into open air camps that had no facilities. The prisoners were treated much in the way that they (the Germans) treated Soviet Army prisoners in that nothing was done for them. Starvation and exposure to the elements. Many of these camps were west of the Rhine (hence Rheinwiegenslager) The lucky Germans who were captured earlier were sent to America or Great Britain where they sat out the war. The unlucky ones who were captured later could be starved or die of disease. Some who were captured were very lucky in that they got jobs with the American Army. They ate regularly, wore GI unforms with white "PW" painted on the back. Only when the Morgenthau Plan (permanently destroy German industry and make it an agricultural nation) was abandoned in favor ot the Marshall Plan (rebuild destroyed nations) did things change. So my question is did the US have the resources to build real camps and feed those PoWs? I know that it would take up resources to get lumber, set up facilities with proper kitchens, latrines, hospitals (to delouse, prevent dysentry, chlorea, typhus or other diseases) and this would draw from any offensive effort. BTW, in my research I learned that everybody deliberated killed certain PoWs especially if they were thought to be snipers. No nation is innocent in that regard.
