 Concerned that more enemy troops might be on their way to the cemetery, Khang and Hay agreed that Ap Binh Long and Ap Hoa Thanh must be retaken the next day so the Allies could restore the security zone around the air base.To help in that effort, Weyand gave Hay operational control over the 1st Battalion, 5th Infantry Regiment, a mechanized unit from the 25th Infantry Division stationed at Cu Chi.The battalion commander, Lt. Col. Thomas C. Lodge, brought his unit to Tan Son Nhut early in the morning where it joined up with the 3/4th Cavalry and the 30th Ranger Battalion, arrayed in attack formation just north of Ap Binh Long.
