Marine planes and artillery cleared the way on 26 January as 1/7 advanced against scattered opposition. Nearly 400 guerrillas put up a ragged and futile resistance, but by 1530 Marine firepower prevailed and Chiso-dong was taken. The 2d Battalion had meanwhile occupied Hapton-ni, eight miles southeast of Topyong-dong ([Map 5]). A light enemy counterattack was repulsed with ease.[62] Altogether, enemy casualties for the day amounted to 161 KIA or POW.
[62] HDs of 1stMarDiv, 7thMar, VMF(N)-513, and VMF-323 for Jan 51.
The VMF-323 flight led by Captain Don H. Fisher and Captain Floyd K. Fulton’s VMF(N)-513 flight merit recognition as the first successful instance of Marine air-ground cooperation since the Chosin Reservoir campaign.
While the 7th Marines served eviction notices on the enemy in its area, action elsewhere was light. Task Force Puller[63] hastened on the 26th to Chongja-dong, seven miles northeast of Uisong, to investigate a police report that 300 enemy had seized the town. A Marine attack, following an artillery preparation, was planned for 1500. Captain Thomas J. Bohannon led Able Company in but discovered that the shells had fallen on empty huts.[64]
[63] Organized from units of RCT-1 on 25 January when Colonel Puller was promoted to the rank of brigadier general. On that date Colonel McAlister assumed command of RCT-1.

During the next few days the rice paddy patrols continued to range over the countryside, searching out the enemy. Combat units were sent to areas where the G-2 red arrows indicated an NKPA buildup. On the morning of the 29th, the 5th Marines tried to organize an attack on a large enemy force reported near Chachon-dong, 12 miles west of Topyong-dong. Captain Jack R. Jones’ Charlie Company, moving out at night in small foot patrols to maintain secrecy, scoured the area in an attempt to pin down the enemy.
Marine intelligence reports had warned of a dawn raid on the town for the purpose of plundering food from the inhabitants and arms from the Korean police station. First Lieutenant Richard J. Schening, executive officer, led a scouting force ahead of the main body to reconnoiter the area. He urged that a trap be set for the enemy, and the company commander has left a description of one of the most elaborate ambushes ever attempted by the Marines during the war:
Well before daylight, a cordon was stealthily braided around Chachon-dong and we settled down to await the raiders. A later daylight inspection of the deployment showed that the men had done a splendid job of locating themselves so as to avoid detection. They were concealed under porches, beneath the brambles, and in the heaviest foliage and trees. But no guerrilla attack materialized, probably due to a “grapevine” warning of our movement and intent.... During the remaining days in the village we conducted extensive patrolling in an attempt to catch at least one guerrilla for our effort. Patrols were kept small to maintain secrecy. We even dressed Marines in clothing worn by the “locals” and sent them out in the hills with wood-gathering details. Larger patrols up to a platoon in size were sent on combat missions at night, One thing was certain: it was easier to talk about capturing guerrillas than it was to lay a hand on them.[65]
