In Germany, stalag (German pronunciation: [%CB%88%CA%83talak]) was a term used for prisoner-of-war camps. Stalag is a contraction of "Stammlager", itself short for Kriegsgefangenen-Mannschafts-Stammlager.
According to the Third Geneva Convention of 1929 and its predecessor, the Hague Convention of 1907, Section IV, Chapter 2, these camps were only for prisoners of war, not civilians. Stalags were operated in both World War I and World War II and were intended to be used for non-commissioned personnel (enlisted ranks in the US Army and other ranks in British Commonwealth forces). Officers were held in separate camps called Oflag. During World War II, the Luftwaffe (German air force) operated Stalag Luft in which flying personnel, both officers and non-commissioned officers, were held. The Kriegsmarine (German navy) operated Marlag for Navy personnel and Milag for Merchant Navy personnel. https://en.wikipedia.org/wiki/Stalag
