- The communists demand the release of all prisoners detained by Saigon – not only the so-called PoWs. This distinction between “prisoners” and “prisoners of war” is significant since the great majority of the NLF members held by Saigon do not have PoW status. Until 1965 there was no such thing as a PoW; NLF prisoners were considered common criminals.
