Laos
The Battle of Ban Pa Dong (between January 31 and June 6, 1961) was lost by Vang Pao's forces against North Vietnamese and the Pathet Lao. The place was where Vang Pao's [so-called secret army or] L'Armee Clandestine had trained its first 5,000 soldiers. The headquarters for Vang Pao was moved to Long Tieng, until the end of the war.
