Line, the PVA 29th Division opened more effective assaults on the 7th Infantry between 20:00 and midnight of the 24th. Two regiments of the division attacking across the Hantan River hit all three battalions of the regiment. Hardest hit was the 2nd Battalion on the right flank, which by 02:30 on the 25th was surrounded. On orders of the regimental commander, the battalion gradually infiltrated south in small groups and reassembled some below the Kansas Line around daylight. The 1st and 3rd Battalions held their ground but remained under pressure throughout the night. In the eastern half of the Corps' sector, the remainder of the PVA 29th Division, the 179th Division and the 81st Division opened and steadily intensified attacks on the 25th Division between dusk and midnight. Simultaneous with frontal assaults on the 35th Infantry at the left, forces of the 29th Division apparently coming out of the adjacent sector of the 7th Infantry to the west drew close enough to place fire on the regimental command post and supporting artillery units. On the right, PVA penetrated and scattered the 1st Battalion, 24th Infantry. Unable to restore the position, General Bradley pulled the 24th Infantry and 27th Infantry onto a new line about to the south but gained no respite as the PVA followed closely. In the 24th Division sector at Corps' right, two PVA companies infiltrated the positions of the 19th Infantry during the night. But a greater danger was posed by the 60th Division, which, after again routing the ROK 6th Division, reached and attacked the right flank of the 21st Infantry. The 21st bent its line and tied it to the position of its reserve battalion on the flank. But the 60th, if it should shift to the south past the refused flank and the blocking position set up by the battalion of the 5th Infantry, could slip into the division and Corps' rear area through the big opening created by the ROK 6th Division's second retreat. Because of this danger on his exposed right flank, the continuing and effective heavy pressure on the 25th Division, and the threat of a major enemy penetration through the wide gap between the ROK 1st Division and 3rd Division, General Milburn at 05:00 on the 25th ordered a withdrawal to the Delta Line, which, as set out in previously prepared Corps' plans, lay , west to east, below the
