My father-in-law entered the service in June, 1944. During his training as a Naval aircrewman, he was stationed at several naval bases, one being located in Corpus Christi, Texas. There his training squadron was familiarized with the big Martin PBM "Mariner" patrol bombers that they would soon be flying over the Pacific Ocean.
There were German prisoners of war held under Marine guard at that base, presumably captured in North Africa or Italy. Rather than build separate a separate mess hall for the POWs, they were simply fed in the same building as the enlisted Navy men and Marines. The prisoners were fed first - always.
