The Easter Offensive in southern Cambodia and the Mekong Delta was part of the People’s Army of Vietnam (PAVN)’s Easter Offensive of 1972 and saw PAVN and Viet Cong (VC) engage the Army of the Republic of Vietnam (ARVN) and Khmer National Armed Forces (FANK) supported by the United States along the southern Cambodian border with South Vietnam and in the Mekong Delta of South Vietnam. The offensive failed to seriously disrupt the vital South Vietnamese supply routes in the Delta or the pacification efforts there.
