Chapter II: Defending the Line (2)

Text size

A new Marine artillery tactic about this time was the counter-counterbattery program instituted by the 11th Marines. The regiment had developed this technique to counter superior enemy artillery strength. This situation, as well as the fact that I Corps artillery available to the division was considered inadequate for counterbattery support, led the Marine division to adopt the new program in May 1952. One provision required a battery in each battalion to select counter-counterbattery positions and occupy them for 24 consecutive hours each week. Another proviso of the program was the selection by each battalion of 10 roving gun positions that were to be occupied by a single weapon rotated to each place at least once weekly. By these tactics, the artillery regiment hoped not only to mislead the Chinese in their estimate of the strength and location of Marine artillery but also to dilute enemy counterbattery intelligence by causing him to fire into areas just vacated by friendly guns. “The effectiveness of the program was demonstrated on numerous occasions when the enemy fired counterbattery into unoccupied positions.”[117] An added advantage was that of providing deeper supporting fires on target areas.[118]

[118] LtCol Bruce F. Hillam comments on draft MS, dtd 31 Aug 66.

Still another concept regarding the employment of artillery developed during the early days of the JAMESTOWN defense. The 11th Marines had advised the infantry regiments that it could effectively fire on enemy troops attacking friendly positions if the Marines had overhead cover. The idea was to use variable time (VT) fuzes[119] with the standard high explosive (HE) shells. Artillery battalions supporting the frontline regiments registered on positions occupied frequently by patrols going forward from JAMESTOWN.

[119] A type of proximity fuze, the V.T. depends upon an
external source, such as an electronic signal, rather
than the force of ground impact, to detonate the shell at
a predetermined height over the target.

According to the recollections of veteran artillery and infantrymen in the division, the first occasion that pre-planned artillery fire was placed on friendly positions occurred in May 1952.[120] The episode involved a 2/7 platoon patrol that late on 18 May was ordered to return to the MLR from an outpost on the former OPLR. Operating forward of the center regimental sector,[121] the platoon commander, Second Lieutenant Theodore H. Watson, directed that two of the three Marine squads return to the MLR. The remaining unit, surrounded by about 50 Chinese, engaged them in a brisk fire fight.

[120] 1stMarDiv ComdD, May 52, p. 4.

[121] The 7th Marines advanced to the line to relieve the 5th
Marines in the center sector on 11 May.

When the artillery fired to seal off the enemy and box-in the defensive position failed to discourage the hostile force, Lieutenant Watson ordered his men into the shelter of two nearby bunkers. He then requested the artillery to place VT directly over his positions.[122] The volleys of overhead fire and effective Marine small arms fire then forced the enemy to call off his assault. Although the exact number of Chinese casualties could not be determined, the new fire technique fully accomplished its purpose--repelling the enemy force.

[122] The artillery regiment had earlier developed the
“box-me-in” fires for outpost defense. If under heavy
attack the outpost could call for these pre-planned
close-in fires that completely surrounded the position.
In event of radio or wire communication failures, the
outpost could call for “box-me-in” or “Fire VT on my
position” by signal flare or other pyrotechnic device.
_Henderson ltr II._

Initiating the infantry action in May was the 1st KMC Regiment, holding the division left flank, with its 2d and 1st Battalions on line. At dusk on 3 May a platoon-size raiding party, under Second Lieutenant Kim Young Ha, left an outpost forward of the 1st Battalion line on a prisoner-taking mission and headed for the objective, Hill 34, adjacent to the rail line to Kaesong and about a half-mile west of the Sachon River. When the platoon was within approximately 1,000 yards of its goal, a support squad was detached near a trail and stream juncture to ambush any enemy attempting to attack the raiders from the rear.[123] The remainder of the platoon, two assault squads, then continued towards the objective, moving cautiously and halting for an hour because of the bright moonlight.

[123] This support squad itself was later ambushed. The
heavy casualties it received prevented its further
participation in the raid. KMC Regt UnitRpt 53, dtd 4 May
52.

After midnight the moon disappeared behind the clouds, and the Koreans again emerged. They advanced towards a village immediately south of the objective. After searching a few houses and not finding any enemy, the KMCs started on the last leg to Hill 34. As soon as the objective came into view the raiders deployed for the assault. At 0410 the two squads of Korean Marines charged the knoll, immediately drawing heavy Chinese small arms fire. When the raiders continued their assault, the enemy retreated to his trenchworks and bunkers where he continued to fire on the KMCs. Since it now appeared to the patrol leader that the probability of taking a prisoner was unlikely, he prepared to return to friendly lines. He first arranged for artillery to cover the withdrawal of the patrol, and then broke off the 18-minute fire fight, taking his only casualty, a wounded rifleman, with him. The KMCs counted 12 enemy dead. No prisoners were taken. In the preliminary action, the support squad had also suffered three killed and seven wounded.

As the KMC raiders were making their way back to the MLR, a combat patrol from 1/5, the reserve battalion of the 5th Marines, prepared to move out. This patrol was one of many dispatched by the battalion during the first week of May in accordance with its mission of patrolling in front of the OPLR, between the MLR and the OPLR, and throughout the regimental sector. On this occasion, the patrol was to occupy the high ground south of former Outpost 3, which had become the focal point of activity in the center sector.[124] When used as a base of fire, this ground provided a position from which automatic weapons could readily cover enemy lines or tie in with adjacent friendly defenses. In addition, the 1/5 patrol was to drop off friendly snipers to cover the former OPLR position, to maintain surveillance, and to ascertain to what extent the Chinese were developing the outpost. The task went to a Company A platoon, which the unit commander, First Lieutenant Ernest S. Lee, reinforced with light and heavy machine guns.

[124] This position, the site of the mid-April battle, along
with several others had been abandoned when the division
withdrew its OPLR late in April. Infantry regiments
dispatched frequent patrols in an attempt to discourage
the enemy’s incorporating the hill into his own OPLR.

At sunup the Marines crossed line JAMESTOWN and before 0900 had reached the high ground they were to occupy. Here the patrol leader set up his base of fire, then pushed on with the rest of his men to the outpost, receiving occasional mortar fire before reaching the old position. While organizing his men at the objective, Lieutenant Lee received word by radio that the Chinese were preparing to attack. Almost immediately, intense shelling struck the forward slope of the hill. A Marine aerial observer (AO) detected 60–70 Chinese advancing from the next hill, some 800 yards to the front of the Marines. The AO also reported that the enemy was firing mortars towards OP 3.

Shortly thereafter the Chinese fire ceased. Moments before it lifted, the patrol received a second warning that an enemy attack was imminent. Even as this message was being received, about 30 Chinese rushed the patrol. The Marines immediately took the hostile assault force under fire, killing 14 CCF with well-placed small arms fire. Overhead, four 1947-vintage Marine Corsair fighters (F4U-4Bs) struck at troublesome mortar positions previously located by the AO. At 1330 another aerial strike against Chinese mortars and enemy positions on the hill north of OP 3 was executed. These two air missions were credited with destroying six mortars, damaging two others, and wrecking seven personnel bunkers. During the second strike the 1/5 patrol began its withdrawal.

On two occasions during the patrol’s return to its base the enemy attempted to ambush it. Each time the attempt was thwarted, once by the patrol itself and the second time, with the help of friendly artillery. On the way back several loud explosions suddenly halted the patrol. Investigation revealed that the Marines, carrying their casualties of one dead and four wounded, had inadvertently stumbled onto a path not cleared of mines. Two members of the stretcher bearer detail were killed and three others wounded by the AP (anti-personnel) mines that had not been charted on friendly maps by the Marines’ predecessors in the defense sector. A mine clearance team promptly disposed of the danger. With the aid of fires from a 2/5 patrol on the nose of a nearby hill, the 1/5 platoon was able to break contact. After pulling back several hundred yards, the patrol reached a forward medical aid station where jeeps picked up the more seriously wounded and took them to helicopters, which completed the evacuation. Patrol members reported 27 known enemy dead, including one that had been propelled into the air by a direct hit from an artillery round.

The next major Marine ground action soon involved the same Company A platoon, but this time as part of a larger force. Colonel Culhane, the regimental commander, directed his 1st Battalion to launch a new raid on the Outpost 3 area in an attempt to oust the Chinese and thereby deny the enemy use of the critical terrain. Inflicting casualties and capturing prisoners were additional tasks assigned. On 8 May Lieutenant Colonel Nihart issued Operation Order 12-52, calling for 1/5 to seize a series of three intermediate objectives (S, V and X) en route to OP 3 (Y). (See Map 8.) The combat patrol, reinforced by regimental elements, less Company B, was to be prepared to move north of OP 3 to occupy the next hill mass (Z), if necessary.

OBJECTIVES FOR 1/5 ATTACK

9 MAY 1952]

Operational plans called for Lieutenant Lee’s Company A to do most of the leg work as the assault unit. Captain Leland Graham’s Company C, the diversionary force, was to make a feint against Hill 67, an enemy position southwest of OP 3, and to neutralize it by fire. Weapons Company, under First Lieutenant Ross L. Tipps, in support of the Company A force, was to set up a base of fire at a designated position (T), southeast of OP 3. Artillery support was to be furnished by 1/11, 4/11, and the attached 4.5-inch Rocket Battery. A section of regimental 4.2-inch mortars was also assigned. One platoon of Company B tanks was to assist the assault force by firing both on designated positions and targets of opportunity. Close air support flights were to be on station at two periods during the 9 May daylight operation.

In the early morning hours, under cover of darkness, all units moved into position. At 0430 the 1st Platoon of Company A crossed the line of departure heading for Objective S, a small ridge south and west of OP 3. The 2d Platoon followed and moved out on the right, while the 3d Platoon covered the rear. This hill, lightly defended, was quickly overrun by the Marines. The 1st Platoon then turned northeast towards the four peaks (designated as V, X, Y, and Z), its main objectives. These four positions were all situated at approximately the same elevation, 450 feet. A distance of some 1,300 yards separated the first and fourth hills in the north-south ridgeline.

As the 1/5 platoon neared Objective V, friendly rockets lashed the crest of the hill, which was held by a reinforced enemy platoon in mutually supporting fighting holes. Assisted by this fire, Marine two-man teams with rifles and grenades assaulted the fighting holes occupied by the Chinese. As the Marines proceeded to clear the objective, half of the Chinese were forced to retreat to safer ground. Marines estimated that 15 enemy were killed and a like number wounded. By this time, three hours after setting out on the raid, the platoon had seized one prisoner and sustained five wounded.

While reorganizing for the attack against Objectives X and Y, the 5th Marines patrol came under a heavy artillery and mortar barrage that killed one Marine and wounded three others. As the main body of the assault force advanced towards Objective X to support the attack, the lead elements of the company headed for OP 3. Throughout this maneuver, the company remained under heavy artillery fire.

Proceeding along the eastern slope of the ridgeline to assault knobs X and Y, the platoon had a good view of the effectiveness of their friendly supporting artillery fire. In fact, the combined rocket, howitzer, mortar, tank, and machine gun fire threw up so much dust that at times it restricted the vision of the Marine assault team. As platoon members neared the summit of Objective X they encountered a heavy stream of defending fire. A strong counterattack from the front and left flank assailed the 1st Platoon, but the Marines repulsed the enemy with accurate small arms fire, killing six CCF. Infiltrators then attempted to envelop the Marine platoon and isolate it from the rest of the Company A assault force. Successive waves of Chinese, employing a wedge formation, tried to overrun the main body of the assault force. In repulsing this latest counterattack, Company A killed 12 and wounded 5 enemy.

Quickly sizing up the situation, the company commander ordered the 1st Platoon to rejoin the rest of the assault force. As the platoon began to pull back at 1435 the Chinese blanketed the route with a heavy barrage, firing “over four hundred rounds in a five minute period.”[125] This intense shelling took the lives of three Marines, wounded a number of others, and halted the assault force just short of its final goal. Even though the Chinese had been driven from the three intermediate objectives, the devastating enemy mortar and artillery fire made the Marine position untenable. A third of the platoon moved back to Objective V; the rest worked their way along a route east of that objective. While the rest of Company A and Weapons Company elements occupied Hill T, the diversionary force, Company C, reinforced by other Weapons Company personnel, had remained at a strongpoint not far from Objective S. All supporting ground weapons assisted in the withdrawal. In addition to lending direct fire support, Marine tanks brought forward emergency supplies and evacuated casualties. By 1730, the assault force had returned to friendly lines, followed shortly by the rest of the battalion.

[125] 1/5 ComdD, May 52, p. 10.

Although the battalion failed to seize and hold all of its objectives, that part of the mission calling for inflicting casualties and taking prisoners had been successfully executed.[126] Marines counted 35 enemy dead, 53 wounded, and 1 POW, and estimated that an additional 70 CCF had been killed and 105 wounded. Seven Marines were killed and 66 wounded in the action described by some observers as “the largest offensive effort the 1st Marine Division [has] made since last September.”[127] The battalion fire support was well controlled and coordinated from an observation post on the MLR. Five air strikes, including one MPQ-14 mission, were credited with destroying three artillery pieces and an equal number of mortars, damaging two other mortars, and demolishing six personnel bunkers.

[126] Lieutenant Colonel Nihart believed that the heavy enemy
shelling, which had caused the early retirement of his
battalion, had been possible either because Chinese
mortar and artillery positions were so well camouflaged
that intelligence had not located them or else so well
protected that UNC counterbattery fire had failed to
destroy them. _Nihart comments._

[127] 5thMar ComdD, May 52, p. 9.

As the regiment noted, the earlier withdrawal of the OPLR had “altered to a considerable extent the tactics employed in this area. This is especially apparent in the number of patrol contacts close to the MLR and displayed the eagerness of the enemy to move in on any ground not held by friendly forces.”[128] At the same time the increased number of troops made available for the MLR defense considerably strengthened the JAMESTOWN Line itself. Sector responsibility changed on 11 May. Colonel Russell E. Honsowetz’ 7th Marines relieved the 5th Marines in the center regimental sector, with 2/7 and 1/7 occupying the left and right battalion positions, respectively.

[128] _Ibid._, p. 1.

When it took over the peace corridor sector the 7th Marines also assumed the responsibility for emergency rescue of the Allied truce delegates at Panmunjom.[129] The regiment advanced a mile nearer the objective when it moved the pick-up force’s assembly area to within 400 yards of the line of departure. The 7th Marines also replaced the tanks in the force with M-39 personnel carriers, a U.S. Army-developed tracked vehicle similar in appearance to the Marine amphibian tractor. Another vehicle the 7th Marines retained in its task force was a medium tank equipped with additional radios. This armored communication and control vehicle was used as a radio relay station on the MLR to assist in liaison between moving infantry and tank units. Marine riflemen dubbed this command tank the porcupine, to describe the effect of many bristling antennas sticking out from its top. While the Marine division right sector, occupied by the 1st Marines, remained relatively quiet during the spring months on JAMESTOWN, the 7th Marines in the center MLR would shortly be involved in the division’s major ground action in late May.

[129] This force and its mission at various times were known as
“Task Force Jig” or “Operation Snatch.”

As part of the active defense of its JAMESTOWN line, Lieutenant Colonel Daughtry, commanding 1/7, issued a directive on 26 May intended to deny to the enemy key terrain remaining on the old OPLR. Operation Plan 16-52 called for an attack to seize two parcels of high ground to the regiment’s right front. At the same time, the battalion was to neutralize two Chinese positions west of the main objectives, Hill 104 (Objective 1) and the Tumae-ri Ridge (Objective 2), approximately a half-mile further north. The designated attack force, Captain Earl W. Thompson’s Company A, was heavily reinforced. While Company A pursued its mission to the right, a Company C reinforced platoon under Second Lieutenant Howard L. Siers would conduct a feint on a pair of enemy positions to the left. Support for the operation would come from 2/11, two tank platoons, and from air, which was to be on call.

H-Hour was set for 0300 on 28 May. Attack and diversionary forces on schedule crossed the line of departure, a half-mile north of the MLR. Captain Thompson’s main force advanced nearly to the base of Hill 104 before the Chinese, in estimated reinforced platoon strength, began to counterattack. The fight came to an abrupt end when Second Lieutenant John J. Donahue led his platoon to the top with bayonets fixed.[130] As the Marines dug in they came under heavy mortar and artillery fire from CCF strongholds to the north. On the left, meanwhile, Lieutenant Siers had received orders to seize the closer of his two objectives, former OPLR 5, instead of merely placing suppressive fire on it.

[130] Maj Kenneth A. Seal comments on draft MS, dtd Oct 66. At
the time of this attack, Lieutenant Seal commanded the 2d
Platoon, A/1/7.

Moving forward from its base of fire, the platoon soon established contact with the enemy. At 0554 the platoon began its attack on the objective. Despite the close-in, hand-to-hand fighting, when it became apparent the assault could not be stopped the enemy gave way to Marine persistence in seizing the hill. By 0700 the Company C, 7th Marines platoon had secured its objectives and begun preparations for defense of the positions as well as continued support of the main attack force. Heavy casualties, however, forced Lieutenant Colonel Daughtry to recall the platoon and it returned to the lines by 0930.

Up on Hill 104, Company A, 1/7 faced practically the same situation. Taking Objective 1 had been costly and the advance through withering enemy fire was adding to the casualties. A reinforcing platoon was sent from the MLR to help the company disengage and return to friendly lines. Contact with the enemy was broken shortly after noon. With the aid of air and artillery, the company was able to make its way to the MLR by 1405.

Advancing only as far as it did, the attack, like the one earlier that month, failed to take all the designated objectives. Casualties to the 1/7 Marines were placed at 9 killed[131] and 107 wounded. Most of the latter were evacuated for further treatment. Forty-five of the enemy were counted dead and three wounded. Marines estimated another 40 enemy killed and 40 more wounded.[132] The action resulted in a casualty toll that was the highest to date for any Marine company in western Korea. All three Company A rifle platoon leaders--Second Lieutenants Donahue, Jules E. Gerding, and Kenneth A. Seal--were wounded. This battle also became the occasion for another unwelcomed record--4,053 rounds of enemy incoming, during a 24-hour period.

[131] Two Marines killed in the action were later posthumously
awarded the Medal of Honor. Corporal David B. Champagne,
A/1/7, was responsible for saving the lives of the
three other members of his fire team. When a grenade
fell in their midst, Champagne grabbed it to hurl back
to CCF positions. Just as it cleared his hand, the
grenade exploded, showering lethal shrapnel into the
body of the 19-year-old Rhode Islander. One of the C/1/7
reinforcement Marines, Private First Class John D. Kelly,
had conducted a one-man assault against a dug-in Chinese
machine gun crew. Though painfully wounded during this
encounter, he disposed of the enemy, then reduced a
second weapons bunker. While firing point-blank into a
third position the brave Marine was fatally wounded. This
1/7 action was the first in the western Korea defense to
result in multiple Medal of Honor awards.

[132] 1/7 ComdD, May 52, pp. 17–18.

Following this late May offensive, a brief period of relative calm settled over the MLR. Marine and Chinese units continued the active defense of their respective sectors, with generally only a limited number of contacts. Fire fights between Marine patrols and CCF defenders lasted only a short time and usually ended when artillery fire caused the patrol to pull back. Even though this state of affairs remained essentially unchanged through June, several other events that month would affect Marine defense of the westernmost sector in I Corps.

A second realignment of the Marine-Commonwealth boundary along Line JAMESTOWN was made on 1 June. Part of the rear of the MLR was moved eastward to enable the Marine division to assume full responsibility for a key ridgetop. Prior to this date the hill mass had been divided along its crest, a factor that made it a potential trouble spot for both divisions. On 23 and 24 June, the 7th Marines MLR battalions relocated their positions towards the enemy along JAMESTOWN. This readjustment of the line varied from 1,300 yards in the center of the regimental sector to 400 yards near its right. The additional terrain strengthened the division front by placing the center regiment on improved and more defensible ground.

A week before this MLR change took place, there had been a shift in occupants in its far right sector. Colonel Culhane’s 5th Marines replaced the 1st on line, which then went into division reserve. Manning the MLR were 2/5 on the left and 1/5 to the right.

In early June the recently appointed UN commander, General Clark, made his first visit to the 1st Marine Division front. During his briefing, General Selden reviewed the unusual combat difficulties confronting his Marines. In addition to the unfavorable terrain, the division commander noted the special operational restrictions caused by proximity to the truce talk site. Presence of a large number of uncharted minefields created another obstacle. Herculean efforts were required of the Marines to simultaneously man and construct defenses over 35 miles of JAMESTOWN. Adding to Marine problems were the facts that ground units were not receiving sufficient close air support and the capabilities of the Chinese were constantly increasing.

Chinese order of battle (OOB) information was fed into the division intelligence network by higher commands, I Corps and EUSAK, and adjacent units, but a large part of the data about Communist forces was produced by the division itself. Frontline units in contact with the enemy, by observation of his activities, supplied the bulk of intelligence about enemy defense tactics, employment of weapons, and combat characteristics. Supporting Marine division units, particularly artillery and armor, fed more facts into the system, mostly through identification of the caliber of enemy shells fired at the Marines. As a result of its missions forward of the line and actions in defense of it, the division reconnaissance company also contributed to the intelligence network. Individual Marines, performing as tactical air observers and artillery air observers, as well as the VMO and HMR pilots, were other important sources readily available to the 1st Marine Division.

G-2 directed the division intelligence effort, including processing of raw material and supplying of updated reports to 1st Division units. The G-2 section also maintained OOB and target identification data on Chinese units and their commanders. Members of the G-2 staff also assisted in interrogation of prisoners of war (POWs), screened the civilians apprehended in unauthorized areas, debriefed Marines exposed to enemy intelligence, and conducted inspections of division internal security. In areas where the 1st Marine Division had only a limited intelligence capability it turned to EUSAK for assistance.

Eighth Army teams augmented the division counterintelligence efforts and provided most of the translation service. In addition, three radio intercept units furnished information to the Marines. The critical importance of this service had been proven during several combat patrols in May when additional information was instantly radioed to a friendly unit under fire.

Other intelligence activities were less beneficial to the Marines. These operations were conducted by Tactical Liaison Officers (TLOs, friendly Koreans trained by U.S. intelligence teams), and members of a Higher Intelligence Detachment (HID), a Korean unit assigned from EUSAK. Both the TLO and HID proved of limited value to the division, due to the generally poor educational background of the agents, their inadequate training, and frequent failure to return from assignments behind enemy lines. Some Marines believed the basic fault in these operatives lay in “an exaggerated opinion of their importance.”[134]

[134] _PacFlt EvalRpt_ No. 4, p. 9-33.

Several division intelligence Marines, in conjunction with training and shore party personnel, took part in an informational activity of a different type. These Marines reconnoitered several friendly islands off western Korea to determine their suitability for division landing exercises. The second one inspected, Tokchok-to, 30 miles southwest of Inchon, was selected. By early June planning had progressed to the point where a program had been developed for bimonthly battalion landing team exercises. The KPR maneuver force, appropriately reinforced, was designated as a participating unit. Landings were to employ boat teams, amphibian tractors, and helicopters. The entire program was designed to provide refresher training for Marines in carrying out their primary mission of amphibious assault. By the end of June, 3/5 and 3/1, in turn, had captured Tokchok-to.

Other training concentrated more on the task at hand. Division units in reserve rehearsed tactics for offensive and defensive warfare. Most ground units conducted extensive schooling in both mine and booby trap detection and clearance. Recognizing that patrolling was an important part of a Marine’s life on the MLR, the division included in its Noncommissioned Officers’ (NCO) Leadership School a thorough indoctrination in patrolling tactics.[135] More than 50 percent of the training at all levels was at night. In addition, an extensive orientation was conducted for newly arrived combat replacements, who could not be committed to action for 72 hours after joining the division.

[135] BGen Austin R. Brunelli ltr to Hd, HistBr, G-3 Div, HQMC,
dtd 13 Sep 66, hereafter _Brunelli ltr_. The division
chief of staff during more than half of 1952, Colonel
Brunelli later observed that the “school produced more
effective patrolling and ... contributed to reducing our
casualties.”

A week after the division’s June replacements landed at Inchon, General Selden’s headquarters received a directive that would affect a number of these new Marines. On 10 June CG, EUSAK ordered his corps commanders to make continuous efforts to secure the identification and changes in the enemy order of battle. Two days later I Corps followed the Eighth Army order with a letter of instruction which called for each I Corps division to “prepare plans for launching swift, vigorous, and violent large-scale raids to capture prisoners, to gain intelligence, to destroy enemy positions and material and/or strong limited objective attacks to improve and strengthen Line JAMESTOWN.”[136] Large scale was defined as an “attacking force limited to battalion or regimental (brigade) size with appropriate armor and artillery support.”[137] Divisions were required to submit detailed proposals for future action by 21 June. Marine division plans for limited objective attacks during July by units of the 7th Marines and KMCs were subsequently prepared and forwarded to I Corps.

One operation conducted north of the 2/5 left battalion sector early on 22 June was not, however, in response to this enemy identification mission. Late the previous day, Company G had sent out a 16-man ambush. Before the Marines reached their destination, a small enemy force, itself lying in wait, began to pour a heavy volume of fire on the Marines. At this point the patrol was ordered to pull back. One group of 10 made it back to the MLR; the remaining Marines headed for a nearby combat outpost in friendly hands. Reports to the company revealed one Marine not accounted for. The outpost commander was directed to search the area for the missing Marine. This reconnaissance by a fire team failed, but a reinforced squad sent out later brought back the body of the Marine who had been killed by Chinese artillery.

While this rescue effort was in progress, another similar action was under way. Not long after its arrival on the MLR, Company E, 2/5 had spotted in the No-Man’s-Land between the two main defensive lines a figure that appeared to be the body of a Marine. Since one man had been reported missing from an earlier 1st Marines patrol, recovery of the body, which had been propped up against a mound of dirt in the open, was undertaken. A special Company E patrol left the main line shortly before dawn on the 22d and reached the recovery area at daybreak. After artillery had laid down smoke, the patrol moved in, quickly recovered the body, and set out for friendly territory. Before the Marines had advanced very far on their return trip, the Chinese interdicted their route with heavy mortar fire, which killed one member of the patrol and wounded another. When the 5th Marines patrol returned to JAMESTOWN shortly after 0700, it carried not only the body it had recovered but also that of the Marine who had been killed on the recovery mission.

By the end of June, major command changes had taken place within the 1st Marine Division as well as in several other UNC components. On 13 June, Brigadier General Robert O. Bare took over the second spot from Brigadier General Twining. Both ADCs were graduates of the Naval Academy and both were native mid-Westerners (General Bare--Iowa, General Twining--Wisconsin). Before joining the 1st Marine Division in Korea General Bare had served at Camp Pendleton, California where most recently he had been commanding general of the Training and Replacement Command. His World War II experience included participation in both European and Pacific campaigns. He was the Staff Officer, Plans, in the U.S. Naval Section for the Allied naval group that planned the amphibious assault at Normandy, France. Later he served in the Peleliu and Okinawa campaigns and, with the ending of hostilities, had participated in the surrender and repatriation of the Japanese in north China.

The outgoing ADC, General Twining, was being reassigned to the Office of the Commandant, HQMC. For his outstanding service as assistant division commander from March through May 1952, he received a Gold Star in lieu of his second Legion of Merit with Combat “V.”

Other high-level changes in command that had also recently taken place had included the UNC commander himself, General Ridgway, who had been succeeded in mid-May by General Clark. Major General Glenn O. Barcus, USAF, had assumed command of Fifth Air Force, replacing Lieutenant General Everest on 30 May. On 4 June, Vice Admiral Robert P. Briscoe had been named the new Commander, Naval Forces Far East to succeed Vice Admiral C. Turner Joy who had held the position since August 1949. And in I Corps, Major General Paul W. Kendall, USA, took over as corps commander on 29 June from Lieutenant General O’Daniel.

The end of the second year of the Korean fighting and the beginning of the third was observed by the Chinese with an attack against the 2d Battalion, 5th Marines, manning JAMESTOWN positions to the left of the regimental sector. Commanded at that time by Lieutenant Colonel Thomas J. Cross, 2/5 was new on line, having relieved 2/1 during the night of 15–16 June.

Late in the afternoon of 24 June, the enemy began registering his mortars and artillery on MLR company positions of 2/5 and a portion of the rear area occupied by the battalion 81mm mortars. Chinese incoming, sometimes intense, sometimes sporadic, continued until shortly after 2130. By this time the CCF were moving down their trenches toward a key outpost, Yoke, known also as Hill 159, which was still occupied on daytime basis by the Marines and lay north of the Company F Sector (Captain Harold C. Fuson). Moments later, the 34 men temporarily outposting Yoke saw the Chinese and opened with small arms fire, but the Marine positions were quickly enveloped by the Chinese. The Americans occupying the forward slopes of Yoke suffered many casualties from the intense fires supporting the enemy rush.

While the initial attack was in progress, the Chinese were able to position and fire machine guns from behind the outpost and in trenches on the forward slopes. Communist mortars interdicted the Marine supply routes to make normal withdrawal and reinforcement measures difficult. The Marines moved into bunkers, called down pre-planned fires, and continued the defense. Although the Chinese had overrun Yoke, they could not evict the Marines. At about 0300, the enemy withdrew. When the 2/5 troops followed to reoccupy the forward slopes of Yoke, the enemy renewed his attack and struck again. As before, the Marines took to bunkers and called in defensive artillery fires. These boxing fires fell around the outpost perimeter until first light when the attackers withdrew for the second time.

Four other outposts in the battalion area were involved in the anniversary attack, but the action around Yoke was by far the heaviest. It resulted in 10 Marines of 2/5 killed and 36 wounded. At Yoke alone, 9 were killed and 23 wounded. Enemy dead were 12 known and 50 estimated killed. Chinese wounded were estimated at 100. At one point during the attack on Yoke, the outpost commander reported that the enemy were wearing gas masks and using tear-gas grenades. Investigation revealed that the Chinese had carried and even worn the masks, but that they had employed white phosphorus grenades rather than tear gas. This was the first instance Marine division personnel had ever encountered of CCF soldiers carrying gas masks in an attack and it was “believed part of the enemy’s hate campaign to impress their troops with the possible use by the UN Forces of CBR (Chemical, Biological and Radiological) warfare.”[138]

[138] Selden, _Div Staff Rpt_, p. 16.

This violent eruption of enemy activity on the night of 24 June was followed by a brief period of greatly reduced ground action. Late on the 29th, however, the battlefront lull was broken when the 1st KMC Regiment sent out a raiding party to capture Chinese soldiers and their weapons and equipment, to inflict casualties, and to destroy positions. Second Lieutenant Kwak Sang In had his reinforced platoon from the 3d Company, 1st Battalion, equipped with rifles, carbines, machine guns, flamethrowers, and explosives. Target for the attack was an enemy outpost four miles south of Panmunjom that overlooked the Sachon River.

The patrol followed the general pattern of previous raids. It made use of supporting elements positioned on high ground in front of the objective. In this action the patrol struck from the rear, using artillery fire for both the assault and the withdrawal. Another similarity existed in that the results were nearly the same--no prisoners taken but fewer casualties to the attackers. One difference from earlier operations was that this patrol employed flamethrowers and TNT for destroying bunkers and inflicting casualties. Both weapons were credited in the killing of 12 and the wounding of 6 Chinese, in destroying 1 mortar and 7 bunkers, and in burning 3 other bunkers and numerous automatic weapons and rifles. Because of the heavy weight of a loaded flamethrower and the small size of the Korean Marines carrying these weapons, the flamethrower operators were fairly well exhausted by the end of the patrol.

_A Long Fourth of July_[139]

1st TkBn ComdDs, Jul 52.

The approach of the American Fourth of July holiday marking an earlier struggle for freedom was appropriately accompanied by ground action initiated by all of the mainland MLR regiments. In the KMC area, a 3 July raiding party struck at forward enemy positions before dawn, killing nine Chinese. In the center regimental sector Colonel Thomas C. Moore’s[140] 7th Marines were also engaged in an active sector defense. In the left battalion spot 3/7, which had replaced 2/7 on line, dispatched raids on each of the first three nights of the month. Its Company G patrol on the night of 2–3 July was to be involved in one of the most costly small unit actions in the western Korea tour of duty for the Marine division.

[140] Colonel Moore took over regimental command on 11 June.
The former CO, Colonel Honsowetz, had been named
Assistant Chief of Staff, G-3 of the 1st Marine Division.

Operational plans called for the platoon night raid on the 2d to be followed by a dawn attack the next morning. In both actions, the prisoner-taking aspect of the mission was considered a primary one. The early part of the operation was uneventful. One platoon moved forward toward the objective, Hill 159 (Yoke), 1,200 yards beyond combat outpost (COP) White, to the regimental left, without making contact with the enemy. The platoon then established a base of fire on favorable terrain from which the attack by the second platoon could be supported.

The second platoon passed through the forward position of the first shortly before 0630 and moved out into enemy terrain. It advanced less than 300 yards before its progress was halted by a Chinese force of battalion strength occupying the objective, Hill 159. Heavy enemy rifle and machine gun fire, hand grenades, mortar and artillery deluged the advancing Marines. Many of them quickly became casualties, but the operation continued, due in part to the determination and initiative of the NCOs. One of these was Staff Sergeant William E. Shuck, Jr., in charge of a machine gun squad. When the leader of one of the rifle squads became a casualty, Sergeant Shuck assumed command of that squad in addition to his own. Although wounded, he organized the two units and led them against the objective. Nearing the summit of the hill, the sergeant was hit a second time. Still he refused evacuation, remaining well forward in the lines to direct his assault force.

It was not until he had received orders to break contact with the enemy that the sergeant pulled back from the attack. During the withdrawal he looked after the other Marine casualties, making certain that all dead and wounded had been evacuated from the zone of action. While directing the last of the evacuation, Sergeant Shuck was struck by a sniper’s bullet and killed by this third hit.[141] He was one of four Marines killed in the engagement. Forty others were wounded. Although no Chinese were captured, Marines estimated the enemy suffered losses of 50 killed and an additional 150 wounded.

[141] The leadership, bravery, and unselfish devotion to duty
earned for Sergeant Shuck the Medal of Honor, an award
made to 14 Marines during the fighting in West Korea.
During the earlier part of the war, 28 Marines had
received the Medal of Honor. Of these, 17 were awarded
posthumously. Five Navy hospital corpsmen, all attached
to the 1st Marine Division, also earned the MOH. These
awards, with one exception, were for heroism under combat
conditions during the 1952–1953 period of the Korean War.

To the east of the 7th Marines, the 5th Marines in the right MLR sector ordered a company-size patrol, also on the night of 2–3 July. Company A, 1/5 was directed to attack successively three outposts in the vicinity of the village of Samichon along the river bearing the same name and two miles beyond the point where the MLR crossed the river. After the reinforced company had taken the first two objectives, which were unoccupied, it received orders from division to return to the battalion area. Despite the fact the patrol had ventured far beyond the Marine lines, it did not come into contact with any Chinese forces.

A 2/5 combat patrol leaving the MLR just after dawn was successful in inflicting casualties on the enemy, taking prisoners, and destroying enemy field fortifications. The patrol made good progress until a Marine inadvertently set off an enemy mine. This mishap gave away the patrol’s location and prompted reprisal by the Chinese. A one-hour fire fight followed. Then the patrol called in smoke and returned under its cover to JAMESTOWN. Marine casualties were 1 killed and 11 wounded. The second 2/5 patrol that same date was a successful ambush completed 10 minutes before midnight. In the brief clash that developed, Marine ambushers killed 6 enemy and wounded 8 more. The Marine force suffered no casualties.

The ambush patrol returned 15 minutes after midnight on 4 July. Even at that early hour division artillerymen had already initiated an appropriate ceremony to mark the Fourth. On 2 July, I Corps had directed the massing of fires on 4 July on the most remunerative targets in each division area. All objectives in the corps sector were to be attacked simultaneously at specified times for a one-minute period by employing a firing technique known as time on target (TOT).[142] Normal daily fires were also to be carried out. Designated as Operation FIRECRACKER, the shoot expended 3,202 rounds in the division sector. Light and medium battalions of the 11th Marines, plus its 4.5-inch Rocket Battery destroyed some enemy trenches, bunkers, mortar and artillery positions, and damaged others. The division reported that the special fires on 4 July had also resulted in 44 known CCF casualties, including 21 dead, and 12 more who were estimated to have been injured.

[142] In the TOT technique, participating units time their
initial volleys to ensure that their shells arrive on the
target at the same time.

More casualties, however, resulted from the issuing of another I Corps directive, this one dealing with the conduct of raids to seize prisoners, obtain information about the enemy, and to destroy his positions, supplies, and equipment. Back in June, the EUSAK commander had first stressed to his corps commanders the increased importance of combat raids to obtain additional intelligence during this period of stabilized conflict.

Although General Selden had submitted two division plans, he strongly believed that smaller patrols could accomplish the objective with fewer casualties and loss of life.[143] In particular, the division commander pointed out to I Corps that adequate defense of the 35-mile-long Marine division front did not permit the withdrawal of a sizable force for patrol missions without endangering the security of the entire Corps sector. The attack order was issued, however, on 3 July for the first large-scale raid to be conducted prior to 7 July. The code name BUCKSHOT 2B was assigned for this particular raid. As soon as he received the date of execution for the proposed operation, the Marine division commander advised I Corps that designation of 7 July as the cut-off date for the raid precluded proper rehearsal of attack plans. The operation would also conflict with rotation to the States of 2,651 Marines, whose replacements would not be available until 11 July. Corps turned a deaf ear; division then ordered a battalion-size attack for the night of 6–7 July.

[143] Among division commanders in the I Corps area, General
Selden was not alone in his grave misgivings of this
method of gaining information about the Chinese. Major
General A. J. H. Cassels, 1st Commonwealth Division,
shared with the Marine commander the belief that such
operations were too costly for the intended purpose.

Before dusk on 6 July, Lieutenant Colonel Daughtry’s reinforced 1st Battalion, 7th Marines moved into position--on the left, a tank-infantry force, A/1/7 (still under Captain Thompson), to create a diversion; in the center, the main assault force, Company C (Captain Robert A. Owens); and on the right, a reinforced platoon from Company B (Captain Lyle S. Whitmore, Jr.) to support the attack by fire from positions close to the objective, Yoke. Earlier, three reinforced squads from Captain Thompson’s unit had occupied combat outposts in the area of operations to deny the use of key terrain to the enemy and to provide additional fire support in the attack. At 2200, Captain Owens’ Company C crossed the line of departure and set its course for Yoke, three-quarters of a mile northeast. Five minutes later the Company B support unit moved out to occupy the intermediate objective, COP Green, one-half mile southeast of Yoke. As it took up positions on COP Green, Captain Whitmore’s Company B platoon discovered that no Chinese were in its vicinity; in fact, the platoon was not to encounter any enemy forces during BUCKSHOT.

Even though Company B failed to engage any Chinese, the remainder of the battalion encountered more than its share. About 450 yards southwest of the objective the Company C attack force was hit by an enemy ambush, which cut off Captain Owens’ lead element. Although the Chinese directed strong efforts at halting the Marine advance, they were unsuccessful in this attempt. The Marines pressed the attack and seized Yoke 20 minutes after midnight.

On the left, the diversionary attack unit, Company A supported by the five tanks of the 2d Platoon, Company D, 1st Tank Battalion, and by a section of flame tanks from the armored battalion headquarters, began its mission at 2355. In three-quarters of an hour, the tank-infantry unit reached its objective, the first high ground southwest of Yoke. Tanks turned their 90mm guns on known Chinese positions on the hill to the north. During the next hour, the big guns of the M-46 medium tanks sent 49 rounds into enemy emplacements. The Marine tanks ceased fire at 0113 when Captain Thompson was alerted to assist Company C. He left one rifle platoon with the tanks.

Over on the high ground to the north and east, the attack force was under heavy fire from Communist mortars and artillery and was also receiving a number of enemy small-unit probes. At 0200, Company A made contact with Company C. Captain Thompson found the main force somewhat disorganized as a result of the wounding of the company commander, Captain Owens, the loss of several key officers and NCOs, and the effects of the lead element of Company C being ambushed and cut off. After being briefed on the situation by Captain Owens and conducting a reconnaissance, Captain Thompson recommended to the battalion commander that the entire force be recalled before daylight. At 0310 the two companies at Yoke began to disengage, returning to the MLR by 0636 on the 7th, without further casualties.

The one platoon of Company A and seven tanks of the diversion unit were still in their forward positions on the left and had prepared to resume firing. At dawn the M-46s relaid their guns on targets that had become visible. Tank gunners destroyed two observation posts and three machine gun positions and damaged many feet of trenchlines. At one point in the firing, the tank platoon commander, Second Lieutenant Terry K. Donk, using a power scope, observed “... two officers in forest green uniforms without equipment. They were definitely giving orders to machine gunners and infantry.”[144] These 2 were among the 19 counted casualties (10 wounded) that the tankers inflicted during BUCKSHOT.

[144] 1st TkBn ComdD, Jul 52.

With the return at 0645 of the tank-infantry diversion force, the special operation for obtaining prisoners and information ended. No Chinese had been captured and no data gleaned from Communist casualties, listed as the 19 reported by the tankers and an estimated 20 more wounded or killed. Marine casualties from the operation were out of proportion to the results achieved--12 dead, 85 wounded, and 5 missing. It had been a high price to pay for a venture of this type, particularly when the primary objectives went unaccomplished.

During the entire 4–7 July period, 22 Marines had lost their lives in combat operations. Division reported that 268 Marines had been wounded during the long Fourth of July. These figures were the highest since September 1951 when large scale attacks by UN forces had first been abolished in line with the new tactic of positional warfare that would be waged until the truce talks resulted in an armistice.

_Changes in the Lineup_[145]

1stMarDiv ComdD, Jul 52.

Division casualties were considerably higher during the first week in July than they were for the rest of the month. Once the pace of combat slowed, following the initial flurry of activity, the front again settled down to the patrol, raid, and ambush routine that had marked the static period of the Korean fighting. In accordance with the orders previously issued by higher authority the division placed continued emphasis on gathering all information it could about the enemy, his dispositions, and tactics. To assist in this effort, General Selden in July removed his reconnaissance company from defense of its small sector of JAMESTOWN and directed the unit to conduct training for its primary mission, obtaining intelligence about the enemy. Its place on the MLR was assumed by the two amphibian tractor companies then on line.

Another change of lineup took place on 14 July. At this time a battalion from the 15th Regiment, U.S. 3d Infantry Division took over the role of the maneuver element in the Kimpo Provisional Regiment, then held by 1/1, thereby releasing that battalion to its parent unit. With this change, the 1st Marine Division had a full regiment in reserve for the first time since its arrival in western Korea. A later shift in units occurred on 26 July when the 7th and 1st Marines traded places and missions. At that time the MLR, from west to east, was manned by the KPR, 1st AmTrac Bn, KMC, 1st Marines, and 5th Marines.

Opposing them in mid-July were an estimated 27 infantry battalions, whose primary missions were to defend the sectors assigned. The division credited these units with the capability of launching limited objective attacks at any time or of taking part in a major attack with a force of up to 57 infantry and 16 artillery battalions, augmented by 40 tanks or self-propelled guns. It was estimated also that the enemy could cross the Han in battalion strength in the vicinity of the northern shore of Kimpo Peninsula at any time and that Communist aircraft could attack anywhere in the division sector. Enemy forces identified at the end of July, from west to east, were the 193d, 195th, and 194th Divisions of the 65th CCF Army; the 189th Division of the 63d CCF Army; and the 118th Division, 40th CCF Army, which had recently moved from a position opposite the Commonwealth and U.S. 3d Infantry Divisions. Infantry strength of the Communists was established at 28,328.
