On the fourth, Lieutenant Colonel Murray ordered the 3d Battalion to pass through the hard-hit 2d Battalion. Company H made a wide arc north of Hill 117 as Company G attacked straight on. This envelopment worked, and Hill 117 quickly fell.
Thereafter, the 3d Battalion conducted a daylong attack that carried the Marines beyond Kang-ni. Simultaneously, the 1st Battalion moved with Companies A and B abreast from Hill 91 East past Yu-ri village, crossed a barren valley, and secured Cloverleaf Hill. There was little resistance during most of the day in the 1st Battalion zone of action south of the road. The Marines advanced three thousand yards over broken ground that day and took all of their objectives before nightfall.
