Nevertheless, Division G-3 was suddenly alerted on the morning of 7 July by the Marine Liaison Officer with X Corps to expect an order directing the setting up of a patrol base on Taeu-san the following day. The KMC Regiment, warned by telephone, had little time for planning and organizing an attack. Since the KMCs could not be relieved for responsibility for their sector, it was necessary to form a composite battalion of the three companies that could most conveniently be relieved. Unfortunately, they contained a large proportion of recruits, and the battalion commander was a new arrival. There were two avenues of approach. One was along an open, fairly level, ridgeline that extended from the KMC positions. The other called for a descent into the stream-bed generally paralleling the MLR and a steep climb up a ridge leading directly north to Taeu-san. Both routes of approach were used. One company advanced on the right by way of the stream bed and two companies took to the ridgeline on the left. The assault was to have been preceded by air strikes and an artillery bombardment, but bad weather kept the aircraft grounded. The attack jumped off at 1030 on 8 July. All three companies were greeted by enemy mortar and machine gun fire that pinned down the company on the right. The two companies on the left won a foothold on Hill 1100, about a mile in front of Taeu-san. Here the advance ground to a halt. These KMCs dug in for the night and repulsed a series of counterattacks. On the morning of the 9th the KMC regimental commander, Colonel Kim Tai Shik, committed the entire 1st Battalion to the attack on the right. It had no better success than the company of the day before. Meanwhile, the two companies were driven off Hill 1100. Colonel Gould P. Groves, senior liaison officer with the KMCs, recommended that the remnants of the two companies be withdrawn. The 1st Battalion had managed to capture Hill 1001, but it was plain that the KMC regiment could not come close to Taeu-san. On 12 July the 1st Marine Division informed X Corps that the position held by the KMCs just forward of Hill 1001 fulfilled the requirements of an advance patrol base. As far as the Marines were concerned, the sad affair was permitted to rest there. As evidence of the valiant effort made by the KMCs, they suffered 222 casualties. A sequel to this story was written late in July after the 2d infantry Division relieved the Marines. X Corps again ordered the capture of Taeu-san as a patrol base, and it required the commitment of the major part of the division to accomplish the task.[251] [251] X Corps _Cmd Rpt_, Jul 51, 13; 2dInfDiv _HD_, Jul 51, 13–19.
