A 1st Marine Division daily intelligence report covering the 24-hour period beginning at 1800 on 24 October noted that there was “a marked increase in enemy artillery and mortar fire with an estimated twelve hundred rounds falling in the CT 1010 area of the 7th Marines sector.”[268] According to the division PIR there was also an increased number of enemy troops observed that same day in locations west and northwest of the Hook. Most of the fire was directed against the Hook area of the MLR and on the two sentinels, Ronson and Warsaw. Efforts by Marines and some 250 KSCs to repair the damaged or destroyed bunkers, trenches, communications lines, and tactical wire, during brief periods of relief from the artillery deluges, were wiped out again by subsequent shellings.

Battalion weapons replied, though in faint voices barely audible in the din created by Chinese firing. Regimental mortars chimed in and so did 2/11, which fired 416 rounds in the 24 hours ending at 1800 on the 24th. For that same period, tanks expended 137 rounds at active weapon positions firing on the Hook. One air strike was directed against the enemy opposing the Hook battalion. This attack by a quartet of Marine F9Fs from VMF-311 (Lieutenant Colonel Arthur H. Adams) bombed and napalmed a troublesome group of Chinese entrenched on the enemy MLR 750 yards east of the Hook. During the next 48 hours, the enemy continued his preparations for an attack, concentrating his artillery fire on the Hook area. Colonel Moore’s battalions received approximately 2,850 artillery and mortar rounds, most of which rained down on 1/7 to the right. There, the heavy and continuous fire slowed Marine efforts to restore their wrecked bunkers and trenches. Late on the 25th there was some relief from the artillery bombardment, but by that time many of the prophets on the line and in the rear area were uncertain only as to the precise time of the unexpected Chinese attack. Colonel Clarence A. Barninger, the division intelligence officer, had himself alerted General Pollock to the implications of “the intensification and character of enemy fires”[269] being received in the 1/7 sector. The intelligence evaluation was not based only on recent events. A detailed study of Chinese capabilities and possible courses of action had just been completed by the G-2 and his staff. In its discussion of the early October outpost attacks in the division right, the report concluded that Chinese interests lay in gaining the “terrain dominating the Samichon Valley....”[270] [269] Heinl, _memo_.
