In response to increasing US air-strikes, the 324B division was deployed increasingly southwards alongside artillery regiments attached to it. These units were stationed along the border, with heavy artillery attached, meant to continually ambush and harass US forces that McNamara and other leaders had posted on the defensive. These units during this time period would never launch a direct attack intending to take any bases directly. In April 1966 U.S. intelligence reported that the 324B was digging in north of the Vietnamese Demilitarized Zone. On the morning of19 May, units from the 324B attacked isolated ARVN outposts at Con Thien and Gio Linh south of the DMZ.
