Artillery plans provided for one battery of 2/11 and one of 3/11 to answer the calls of RCT-7 for supporting fires. The other batteries of 3/11 were to move south with the motor column while two batteries of 1/11 supported RCT-5. The remaining battery of 3/11 was attached to 2/11 with a mission of moving south to Chinhung-ni and taking a position from which to support the withdrawal of RCT-1 as rearguard. Easy Battery of 2/11, left behind at Koto-ri, was laid to fire to the north and west, while Fox Battery of 2/11 and the 92d Armored Field Artillery Battalion at Chinhung-ni supported the attack of 1/1 on Hill 1081. The plan of the 1stMAW for air support was essentially the same as the one which proved so effective during the advance from Hagaru to Koto-ri. An object lesson of that movement had been the personnel and equipment losses suffered by the Division trains as a consequence of a late start. The planners were determined not to repeat this mistake. As a further precautionary measure, General Smith directed that the tanks form the last elements of the motor column.[589] Thus in the event of a breakdown on the twisting, single-lane road, it would not be necessary to abandon all the vehicles behind a crippled tank.

As for the enemy situation, G-2 summaries indicated that early in December the CCF 26th Corps, consisting of the 76th, 77th and 78th Divisions, reinforced by the 94th Division of the 32d Corps, had moved down from the north and taken positions on the east side of the MSR between Hagaru and Koto-ri. There they relieved the 60th Division, which moved into the area south of Koto-ri. The 76th and 77th Divisions occupied positions along the MSR in the Koto-ri area, while the 78th and 94th Divisions were apparently held in reserve. Elements of the 89th Division, operating from the mountainous area southwest of Koto-ri, conducted harassing operations against the MSR in the vicinity of Chinhung-ni as well as Koto-ri. The 60th CCF Division held prepared positions on the high ground south of Koto-ri commanding Funchilin Pass and the MSR leading to Chinhung-ni. That these positions included Hill 1081, the dominating terrain feature, was revealed by prisoners taken in the vicinity by patrols of the 1st Battalion, 1st Marines, prior to 8 December. _Battle of 1/1 in the Snowstorm_ Division plans had not called for the swirling snowstorm which reduced visibility to 50 feet and precluded air support at first light on 8 December. In spite of weather conditions, the assault battalions of RCT-7 moved out from Koto-ri on schedule after 1/1 attacked northward from Chinhung-ni.
