Belgian Battalion successfully withdrew to the east and took up new positions south of the Glosters and the Fusiliers before moving to the vicinity of the 29th Brigade's command post. At around 20:30 on 23 April, the Glosters' A Company, now at less than half strength and with all officers killed or wounded, fell back to Hill 235. The withdrawal left D Company's position exposed, and with one of its platoons badly mauled in the overnight fighting, it too withdrew to the hill. B Company had not been pressed during the night, but the withdrawal of D Company on their left and the Fusiliers on their right left them exposed, and they were withdrawn to Hill 316, east of C Company. During the night of 23/24 April, the Glosters' B Company, outnumbered 18:1, endured six assaults, calling in artillery on their own position to break up the last of them. Low on ammunition and having taken many casualties, the seventh assault at 08:10 forced them to abandon their position, and just 20 survivors made it to Hill 235, to which battalion HQ, the Support Company and C Company had already withdrawn. As B Company fought for its life, the PVA 188th Division crossed the Imjin and attacked the Fusiliers and the Royal Ulster Rifles on the right of the brigade's line. The 187th Division also engaged the brigade's battalions on the right, while the 189th Division kept up the pressure on the left. Most dangerous for the integrity of the 29th Brigade was the deep penetration of the line between the Glosters and the Fusiliers which had cut off the former. To counter the PVA attack and protect the Glosters from being completely surrounded, the Philippine 10th Battalion Combat Team (BCT) was temporarily attached to the 29th Brigade. A combined force of M24 tanks of the 10th BCT and Centurions of the 8th Hussars supported by infantry reached a point from Hill 235 on 24 April. However, the column failed to make contact as the lead tank was hit by PVA fire and knocked out, blocking the route and making any further advance against heavy resistance impossible. At this point, according to an official American narrative of operations, "the brigade commander considered it unwise to continue the effort to relieve the Gloucester Battalion and withdrew the relief force".
