[258] The Marine division artillery regiment reported that in late October nine battalions of Chinese artillery, ranging from 75 or 76mm guns or howitzers to 122mm howitzers, opposed the 7th Marines. It was estimated that one other 122mm battalion was also emplaced north of the right division sector. In addition to these CCF units, elements of a 152mm self-propelled howitzer unit were also believed to be in the area. Late in November two batteries of 152mm howitzers were tentatively located about 4,000 yards west northwest of the Hook. Disposition had been determined “as a result of crater analysis, shell reports, sound plots, and capabilities of the weapon.” 11thMar ComdD, Nov 52, “Enemy Artillery Activity Rpts,” Nos. 21, 23, dtd 1, 21 Nov. 52.
During the summer and early fall, the 7th Marines had amassed considerable information about the enemy, including Chinese strength and composition of forces and many of their combat characteristics. Encroachment on Marine ground positions by steadily creeping the CCF trenchline forward continued to be the enemy’s major ground-gaining tactic. In fact, the Chinese units facing the Marine division concentrated their digging during the fall of 1952 in the sector north of the 7th Marines MLR. (See [Map 15].) Other intelligence, however, seemed open to question. For example, there was the reported frontline presence of women among the 90 Chinese who had engaged a 2/1 patrol on 5 October as well as the sighting in the KMC sector on the 17th of enemy “super soldiers” far taller than the ordinary Chinese. Many in the division found it difficult to believe the statements of enemy prisoners. During interrogation they invariably maintained that the mission of Chinese Communist Forces in Korea was a “defensive” one.

MARCH-OCTOBER 1952
The static battle situation encouraged the use of psychological warfare. In attempting to influence the minds of their opponents and weaken morale, the Chinese depended upon loudspeakers to carry their propaganda barrage across No-Man’s-Land. Enemy employment of this technique was especially heavy during October. To Marines, for example, Chinese directed pleas of “Go home and have peace,” “Surrender, we treat POWs well,” “Leave Korea,” “Marines, come and get your buddies’ bodies,” and the like, often to the accompaniment of music. On occasion, Chinese patrols left propaganda pamphlets behind them in the KMC sector. Infrequently, the enemy displayed signs along patrol routes urging Marines to surrender. Most of the Chinese psychological efforts were directed against the Korean Marines.
In enemy employment of artillery, Marine frontline units and division intelligence had become well aware of the vast improvements the Communists had made in recent months. Aided by a plentiful supply of ammunition, enemy guns and howitzers, including the heavy 152mm weapon, frequently delivered concentrated fires on critical positions in the division area. Marines felt the effects of how well the Chinese had learned to mass their fires against a single target for maximum destructive power. From the Marines, moreover, the enemy had picked up the artillery box tactic, employing it for the first time in their sector opposite Colonel Moore’s regiment during the early October outpost battles.
During those same clashes, the 11th Marines had observed how the Chinese displaced some of their batteries well forward for more effective artillery support of their attacking infantry. One enemy artillery innovation had been noted the previous month by a Marine AO; on 19 September a Chinese artillery piece was detected firing in the open. Previous observations had indicated that the Chinese generally used wooded areas or extensive bunker-type positions to conceal their supporting weapons.
By the middle of October, 62.5 percent of the Chinese artillery opposing General Pollock’s division was located in positions north of the 7th Marines. The importance the enemy put on the principle of massed artillery fire and the improvement of their ammunition supply can be seen in a remark attributed to a Chinese division commander:
