As for the next attempt to relieve Fox Company and open the MSR to Hagaru, the joint planners at Yudam-ni decided on the night of the 28th that all troops of the two regiments now in line were needed for defense. There were actually no men to spare for a relief column, and yet Division had ordered the effort to be made. The solution seemed to be a composite battalion consisting of perimeter reserve units. In order to replace these troops, personnel were to be assigned from headquarters units and artillery batteries. This was the genesis of the Composite Battalion, consisting of elements from Able Company of 1/5, Baker Company of 1/7 and George Company of 3/7, reinforced by a 75mm recoilless section and two 81mm mortar sections from RCT-7 battalions. These troops were directed to assemble at the 1/7 CP on the morning of the 29th, with Major Warren Morris, executive officer of 3/7, in command.[420] [420] This account of the Composite Battalion is derived from the following sources: Narrative of Maj W. R. Earney, n. d., 5–8; 3/7 _SAR_, n. p. At 0800 the striking force moved out southward with the dual mission of relieving Captain Barber and opening up the MSR all the way to Hagaru. After an advance of 300 yards, heavy machine-gun fire hit the column from both sides of the road. Groups of Chinese could be plainly seen on the ridges, affording remunerative targets for the 81mm mortars and 75 recoilless guns. Forward air controllers soon had the Corsairs overhead to lead the way. At a point about 4500 yards south of Yudam-ni, however, Marine planes dropped two messages warning that the enemy was entrenched in formidable force along the high ground on both sides of the MSR. Similar messages were delivered by the aircraft to the regimental CP at Yudam-ni. They caused Colonel Litzenberg to modify the orders of the Composite Battalion and direct that it relieve Fox Company and return to Yudam-ni before dark. By this time Morris’ troops had become engaged with large numbers of Chinese who were being constantly reinforced by groups moving into the area along draws masked from friendly ground observation. Litzenberg was informed on a basis of air observation that Morris was in danger of being surrounded, and at 1315 he sent an urgent message directing the force to return to Yudam-ni. Contact was broken off immediately with the aid of air and artillery cover and the Composite Battalion withdrew without further incident. _The Turning Point of 30 November_ The Yudam-ni area had a relatively quiet night on 29–30 November. But even though there was little fighting, the continued sub-zero cold imposed a strain on the men when at least a fifty per cent alert must be maintained at all times. This was the third virtually sleepless night for troops who had not had a warm meal since the Thanksgiving feast.
