On 1 April, Toàn returned the headquarters and two battalions of the 48th Regiment to the 18th Division. The regiment moved to the Xuân Lộc area but sent its 2nd Battalion to Hàm Tân District on the coast of Bình Tuy Province to secure the city and port. Large numbers of refugees poured into the province from the north. About 500 troops, survivors of the ARVN 2nd Division, were among those arriving from I Corps. When reorganized and reequipped, they would take over the security mission in Hàm Tân. The 52nd Regiment meanwhile was pressing forward on Route 20 south of Định Quán and in sharp fighting on 1 April killed over 50 PAVN troops. The 43rd Regiment was fighting east along Highway 1, near Xuân Lộc and in contact with a major PAVN force.
