The events leading up to, on, and following January 31, 1968 made military history, with a devastating event known as the Tet Offensive. Staged by the National Liberation Front guerrillas (Viet Cong) and North Vietnam Army troops as a surprise attack against the republic of South Vietnam, the Tet Offensive found General Nguyen Giap staging faux battles in the South Vietnamese countryside, to lure American and South Vietnamese soldiers away from Saigon and other cities, and render those areas more vulnerable. The tactic not only worked, but virtually paved the way for the April 1975 fall of Saigon - delivering a deafening blow from which the area never recovered. As narrated by Gavid McFadyen (Treasure Seekers), the documentary program Battlefield Vietnam: Tet! chronicles these events in three installments: "Countdown to Tet," "The Tet Offensive" and "The Fall of Saigon," with biographical studies of the various military leaders, discussions of troop deployments, and a detailed chronicle of the offensive itself.
