forces would eventually train some soldiers to function as so-called “tunnel rats.” These soldiers (usually of small stature) would spend hours navigating the cramped, dark tunnels to detect booby traps and scout for enemy troops. and South Vietnamese infantrymen, planting trip wires that would set off grenades or overturn boxes of scorpions or poisonous snakes onto the heads of enemy troops. VC soldiers lurking in the tunnels set numerous booby traps for U.S. In addition to providing underground shelter, the Cu Chi tunnels served a key role during combat operations, including as a base for Communist attacks against nearby Saigon.

In some areas there were even large theaters and music halls to provide diversion for the troops (many of them peasants) and their supporters. In heavily bombed areas, people spent much of their life underground, and the Cu Chi tunnels grew to house entire underground villages, in effect, with living quarters, kitchens, ordnance factories, hospitals and bomb shelters. At its peak during the Vietnam War, the network of tunnels in the Cu Chi district linked VC support bases over a distance of some 250 kilometers, from the outskirts of Saigon all the way to the Cambodian border.ĭid you know? "Tunnel rats," as American soldiers who worked in the Cu Chi tunnels during the Vietnam War were known, used the evocative term "black echo" to describe the experience of being in the tunnels.Īs the United States relied heavily on aerial bombing, North Vietnamese and VC troops went underground in order to survive and continue their guerrilla tactics against the much better-supplied enemy. As the United States increasingly escalated its military presence in Vietnam in support of a non-Communist regime in South Vietnam beginning in the early 1960s, North Vietnamese and Viet Cong troops (as Communist supporters in South Vietnam were known) gradually expanded the tunnels. Tunnels were often dug by hand, only a short distance at a time. Communist forces began digging a network of tunnels under the jungle terrain of South Vietnam in the late 1940s, during their war of independence from French colonial authority.
