During the 22-hour battle on East Hill the 7th Marines had been attacking toward Koto-ri (see Map 28). On the eve of the breakout the gaps in the infantry ranks were partially filled with 300 artillerymen from the 11th Marines, bringing Litzenberg’s strength up to about 2200 men. 7th Mar OpnO 14-50 called for the advance to be initiated at first light on 6 December as follows: 1st Battalion--to move out at 0430 to clear the ground to the right of the river; 2d Battalion--supported by tanks, to attack as advanced guard along the MSR; Provisional Battalion (31/7)--to clear the ground to the left of the MSR;[561] [561] Since the ground to the left of the MSR was too cut up to permit advance through the high ground, the Provisional Battalion was to operate from the valley and clear enemy from noses found to be occupied. Litzenberg Comments, 5 Oct 56. 3d Battalion--to bring up the rear of the regimental train, with George Company disposed along both flanks as security for the vehicles.[562] [562] Sources for this section, except where otherwise noted, are: 7thMar _SAR_, 24; 3/7 _SAR_, n. p.; Smith, _Notes_, 1029–1031, 1033–1047; RCT-7 _URpt 6_; 1stLt J.

Daybreak revealed a peculiar silvery fog covering the Hagaru area.[563] The 1st Battalion, with Charlie Company in assault, had as its first objective the high ground southeast of Tonae-ri. No resistance was encountered, though 24 Chinese were surprised asleep in their positions near the objective and 17 of them killed. [563] Litzenberg Recollections, 2 Oct 56. The 2d Platoon of Dog Company, 1st Tank Battalion, was attached to 2/7 when the advance guard jumped off at 0630 from the road block south of Hagaru. Almost immediately the column ran into trouble. Upon clearing the road block the lead dozer-tank took three hits from a 3.5 bazooka. Within twenty minutes the column came under heavy fire from CCF positions on the high ground on the left. Fox Company, in the lead, was allowed to pass before the enemy opened up on the Battalion Command Group, Dog-Easy Company and Weapons Company. The fog prevented air support initially. When it lifted, First Lieutenant John G. Theros, FAC of 2/7, brought in Marine aircraft and 81mm fire on the CCF position.[564] It took a coordinated attack by the two infantry companies and the tanks, however, before the resistance could be put down and the advance resumed at 1200. Two and a half hours later the upper reaches of this hill were cleared by D/5.
