During the rest of the day, gunners of the 11th Marines continued their fire missions despite reduced visibility that hindered surveillance by the OY spotting planes and forward observers. Only 42 Chinese were sighted during the daytime, although shortly before dusk a CCF group reportedly heading toward the Berlins area southwest from Frisco was taken under fire. Estimates of enemy incoming throughout the 7–8 July action from 17-odd battalions of Chinese artillery dug in across the division sector was placed at 19,000 rounds of all types. Marine and Army-controlled battalions, for their part, pounded Chinese strongholds with a total of 20,178 rounds. That night Colonel Funk authorized a 3d Battalion platoon to bolster the MLR. Five tanks were also ordered to locate in the Hill 126 area, the Marine high-ground terrain feature to the rear of the frontlines. This foresight was well rewarded. During the late evening hours strange motor noises “sounding like a convoy pulling in and then back out again”[492] floated over the Korean hills and the tanks immediately swept suspected hostile installations with their 90mm guns. Later that night of 8–9 July, the Chinese suddenly renewed their probing efforts at the battered Marine outposts. Moving in from Vegas, an estimated reinforced enemy company attacked Berlin at 0104, then brushed on to East Berlin. An intense fire fight ensued off and on for nearly two hours at the two posts. Marine 81mm and 4.2-inch mortars, plus artillery illumination, boxing fires, and tanks blunted the assaults. At 0315 the enemy broke contact and action quieted down at both locations.

A total of 25 rounds of shells and 19,140 rounds of .30 and .50 caliber machine gun bullets were expended on CCF strongpoints and troops during a 24-hour firing period that ended at 1700. [493] On 9 July Company C relieved Company B on the MLR in support of the 7th Marines. Both tank companies had been in action with the TAFC during the entire 60-day period the division was in I Corps reserve. Due to the rotation system, however, Baker Company had been on line longer and transferred to the rear ranks for a “much needed rest and rehabilitation.” 1st TkBn ComdD, Jul 53, p. 3. Because of the casualties at Berlin, an H/3/7 reinforcement squad was sent to augment the Marine force there. Losses suffered by the 7th Marines for the two successive nights were 9 killed, 12 missing,[494] 126 wounded and evacuated, and 14 with minor wounds. The cost to the CCF was 30 known dead, and an estimated 200 killed and 400 wounded. [494] Later it was determined that only two were actually captured and they were subsequently repatriated.
