General Westmoreland had reported on 3 April evidence of the presence of elements of the 325th Division of the People's Army of [North] Vietnam in South Vietnam. This discovery plus the deteriorating security situation in I and II Corps Tactical Zones was the background of both the diplomatic probes to obtain Free World forces and the preparation of a Joint Chiefs plan of action and time schedule to send a two- or three-division force into South Vietnam.
