An Oflag (from ) was a prisoner of war camp for officers only, established by the German Army in both World War I and World War II in accordance with the requirements of the Geneva Convention (1929) (or the 1899 Hague Convention in World War I). Officers cannot be required to work. A limited number of non-commissioned soldiers working as orderlies were allowed in Oflags to carry out the work needed to care for the officers. Officers of the Allied Air Corps were held in special camps called Stalag Luft, but were accorded the required preferential treatment.
