Into the Iron Triangle

In early October 1966, the fresh and inexperienced 196th Light Infantry Brigade of the US Army was conducting a Series of routine patrols in War Zone C. A lucky discovery of a rice cache led to the uncovering of a planned base area being established by the Viet Cong insurgents of South Vietnam (the National Liberation Front, or NLF) southeast of Tay Ninh City. What followed was named Operation Attleboro.
Unbeknownst to the US and ARVN forces the NLF's 9th Division was preparing to attack the brigade in its base, along with two ARVN positions near Tay Ninh. American moves spoiled the planned attack and initiated a prolonged battle that at its height would pit four regiments of the NLF and People's Army of Vietnam (PAVN) against 18 American and three ARVN battalions, supported by 24 artillery batteries and countless fixed wing and helicopter sorties, including 225 B-52 strikes.
