Kou Voravong
Early in 1950, when Bounkong and his band engaged in violent anti-government campaigns in the South of the country, Kou Voravong created the "Pacification of Southern Laos Mission" to combat internal subversion and border piracy. This organization whose headquarter was based in Pakse, was responsible to bring together supporters, volunteers and former members of the Lao Issara movement, to form units to combat subversion and banditry. Occupied with his ministerial responsibilities in Vientiane, he entrusted the command to his cousin and brother-in-law, the young lieutenant Phoumi Nosavan.
