Jungle Mission is a poignant account of René Riesen’s life and mission during the First Indochina War amongst the Montagnards, and his ever growing love for these people by going native, learning their language, their traditions, their rituals, and their way of life. During World War II, Riesen worked briefly for the Vichy government and, following liberation, received a 20-year prison sentence. He volunteered to serve in the “BILOM” (Bataillon Leger d’Infanterie d’Outre-Mer), where WWII political prisoners could redeem themselves. Arriving in Saigon in May 1950 as a Colonial Infantry “2eme Classe” soldier affected to the BILOM—which by then had ceased to exist and most of its soldiers assigned to the BMEO (“Bataillon de Marche Extreme Orient”) created in January 1950—Riesen was assigned to the 1st Company, 4th BMEO at the outpost of Kon Plong, controlling access to the coastal plains of Son Ha and Ba To; this post was located about a day’s travel away from Kontum, positioned on a 1,800m high peak, where the rainy season lasted about seven months, with thick fog present almost every day. In December 1950, the 4th BMEO was renamed to the 4th Montagnard battalion, and its HQ remained at Ban Mé Thuot whilst its Battalions operated around Kontum. Riesen would go on to serve four years in the Kontum area and joined the GCMA after its formation, serving under Captain Hentic (“L’action Hre”). For his services in French Indochina, Corporal Riesen was awarded the French Croix de Guerre, the Croix des T.O.E (Théâtres d’opérations extérieures) and the Croix de la Vaillance Vietnamienne, with palm for his actions in French Indochina. As with many others, following his tour in Indochina Riesen was sent to the much quieter operational theatre of Algeria; however, this area too did not remain peaceful for long, escalating quickly into full warfare, and Riesen and his wife died during an ambush by Arabs in December 1956.
