The Patriotic Neutralists were an armed political movement of the Laotian Civil War. Founded in April 1963 by a schism within the Forces Armee Neutraliste (FAN) when the latter favored alliance with the Royal Lao Army, the Patriotic Neutralists allied themselves with the opposing Communist forces in the war. The most notable military action that involved them was a devastating air raid on 13 October 1969 that killed all its officers except commanding officer Colonel Deuane Sunnalath. Although it retained a nominally separate identity from the Pathet Lao, Patriotic Neutralist leaders Deuane Sunnalath and Khamouane Boupha would succeed to ministerial posts in the communist-dominated Provisional Government of National Union on 9 April 1974.
