Tây Ninh
Because of the once-vaunted political and military power of the Cao Dai, this region was the scene of prolonged and heavy fighting during the First Indochina War. Tây Ninh province served as a major terminus of the Ho Chi Minh trail during the American War, and in 1969 the Viet Cong captured Tây Ninh town and held it for several days. During the period of conflict between Cambodia and Vietnam in the late 1970s, the Khmer Rouge launched a number of cross-border raids into Tây Ninh province and committed atrocities against civilians. Several cemeteries around Tây Ninh are stark reminders of these events.
