Not so lucky was a 2/5 reconnaissance patrol. At midnight, its 15 members encountered a band of 30 to 40 Chinese, deployed in a V-shaped ambush in the Hill 90 area, an enemy stronghold two miles east of Panmunjom. The Marines set up a base of fire, beating off the enemy with their rifles, BARs, mortars, and bare fists. Reinforcements and artillery fires were called in. The first relief unit was intercepted by vicious mortar shelling which wounded the entire detail. A second relief squad, also taken under mortar fire, continued the action in an intense fire contest that lasted nearly two hours. In the meantime, the direct support artillery battalion, 3/11, reinforced by 1/11, showered 280 rounds of countermortar on Chinese long-range machine guns and mortars barking from the surrounding hills.
During the engagement the Chinese made several attempts to capture prisoners. When the enemy finally began to withdraw, CCF casualties were 10 known dead, an estimated 9 more dead, and 3 wounded. Seven Marines were found to be missing after the Chinese broke contact. A 5th Marines platoon that extensively screened the battalion front during the hours of darkness on the 17th returned at 2210 with six bodies.
The third encounter took place not long after midnight in the 7th Marines territory. This brief skirmish was also to have an unpleasant aftermath and, inadvertently, fulfill the psywar broadcast of the previous day that had warned Marines “not to go on patrols or be killed.” As it was leaving the Ava Gate (250 yards northwest of the outpost proper) at 0045, a 30-man combat patrol from Company A was challenged on three sides by 40–50 CCF employing small arms, automatic weapons, grenades, and mortars. After a 15-minute fire exchange, during which the patrol lost communications with its MLR company, the enemy withdrew. Six CCF had been counted dead, and 12 more estimated killed or wounded.
Upon returning to the outpost, a muster of the men engaged in the action showed four Marines were missing. A rescue squad recovered three bodies. When, several hours later, daylight hampered movements of the search party, 2/11 laid down a smoke screen to isolate the sector. Between 0050 and 0455, its gunners also directed 529 rounds of close support and countermortar fire on Chinese troops and active weapons in the area. The recovery unit continued to sweep the area for the last missing man until 0545 when it was decided that the search would have to be terminated with negative results. Marine casualties from the encounter were 3 killed, 1 missing, 19 wounded (evacuated), and 2 nonseriously wounded.
The following day patrol activity and enemy contacts quieted down. Action shifted to the 1st KMC/RCT sector. Here, during the late hours of the 18th, four Korean combat patrols brushed quickly and briefly with Chinese squad and platoon units in light skirmishes of but a few minutes duration. The Korean Marines killed 2 of the enemy and estimated they accounted for 16 more.[499]
[499] ROKMC Comments.
The only activity in the Marine right regimental sector occurred when a 7th Marines 36-man combat patrol, on prowl the night of 17–18 July, advanced at 0112 as far as hand-grenade range of the Chinese trenchline at Ungok. Undetected by the enemy, a patrol member fired a white phosphorus rifle grenade squarely at the CCF machine gun that was harassing the friendly MLR. The Marines then engaged 15 Chinese defending the position in a brief 20-minute skirmish. Although two men were wounded,[500] the Company C patrol members in a somewhat roguish gesture as they left also planted a Marine Corps recruiting sign at their FPOA (Farthest Point of Advance), facing the enemy.
[500] One, who died that morning, was squad leader Sergeant Stephen C. Walter, posthumously presented the Navy Cross. Also awarded the nation’s second highest combat medal for extraordinary heroism in a patrol action on 16–17 July was Private First Class Roy L. Stewart, of the 5th Marines.
