Although officers were not required to work, at Oflag XIII-B (Hammelburg) when the POWs asked to be able to work for more food, they were told the Geneva Convention forbade them from working.[1][2] In some Oflags a limited number of non-commissioned soldiers working as orderlies were allowed to carry out the work needed to care for the officers. Officers of the Allied air forces were held in special camps called Stalags Luft but were accorded the required preferential treatment.
