Korean War

After withdrawing from Bloody Ridge, the Korean People's Army (KPA) set up new positions just 1,500 yards (1,400 m) away on a seven mile (11 km) long hill mass. If anything, the Communist defenses were even more formidable here than on Bloody Ridge.

, the X Corps commander, seriously underestimated the strength of the North Korean position. They ordered a lone infantry regiment—the 23rd—and its attached French battalion to make what would prove to be an ill-conceived assault straight up Heartbreak's heavily fortified slopes.

All three of the 2nd Division's infantry regiments participated, with the brunt of the combat borne by the 23rd and 9th Infantry Regiments, along with the attached French Battalion. The attack began on September 13 and quickly deteriorated into a familiar pattern. First, American aircraft, tanks, and artillery would pummel the ridge for hours on end, turning the already barren hillside into a cratered moonscape. Next, the 23rd's infantrymen would clamber up the mountain's rocky slopes, taking out one enemy bunker after another by direct assault. Those who survived to reach the crest arrived exhausted and low on ammunition. Then the inevitable counterattack would come—waves of North Koreans determined to recapture the lost ground at any cost. Many of these counterattacks were conducted at night by fresh troops that the North Koreans were able to bring up under the shelter of neighboring hills. Battles begun by bomb, bullet, and shell were inevitably finished by grenade, trench knife, and fist as formal military engagements degenerated into desperate hand-to-hand brawls. Sometimes dawn broke to reveal the defenders still holding the mountaintop.

And so the battle progressed for two weeks. Because of the constricting terrain and the narrow confines of the objectives, units were committed piecemeal to the fray, one platoon, company, or battalion at a time. Once a particular element had been so ground up that it could no longer stand the strain, a fresh unit would take its place, until the 23rd Infantry as a whole was fairly well shattered.

The fighting was savage—no quarter was given or asked by either side—and the ridgeline (called Heartbreak by the American infantrymen) changed hands many times in an exhausting series of attacks and counterattacks. Several units up to company size (100-200 men) were wiped out. The Americans employed massive artillery barrages, airstrikes and tanks in attempts to drive the North Koreans off the ridge, but the KPA proved extremely hard to dislodge.

Finally, on September 27, the 2nd Division's new commander, Maj. Gen. Robert N. Young

, called a halt to the "fiasco" on Heartbreak Ridge as American planners reconsidered their strategy.

As long as the North Koreans could continue to reinforce and resupply their garrison on the ridge, it would be nearly impossible for the Americans to take the mountain. After belatedly recognizing this fact, the 2nd Division crafted a new plan that called for a full division assault on the valleys and hills adjacent to Heartbreak to cut the ridge off from further reinforcement. Spearheading this new offensive would be the division's 72nd Tank Battalion, whose mission was to push up the Mundung-ni Valley west of Heartbreak to destroy enemy supply dumps in the vicinity of the town of Mundung-ni.

It was a bold plan, but one that could not be accomplished until a way had been found to get the 72nd's M4A3E8 Sherman tanks into the valley. The only existing road was little more than a track that could not bear the weight of the Shermans. Moreover, it was heavily mined and blocked by a six foot (2 m) high rock barrier built by the North Koreans. Using shovels and explosives, the men of the 2nd Division's 2nd Engineer Combat Battalion

 braved enemy fire to clear these obstacles and build an improved roadway. While they worked, the division's three infantry regiments—9th, 38th, and 23rd—launched coordinated assaults on Heartbreak Ridge and the adjacent hills. By October 10 everything was ready for the big raid. The sudden onslaught of a battalion of tanks racing up the valley took the enemy by surprise. By coincidence, the thrust came just when the Chinese 204th Division was moving up to relieve the North Koreans on Heartbreak. Caught in the open, the Chinese division suffered heavy casualties from the American tanks. For the next five days the Shermans roared up and down the Mundung-ni Valley, over-running supply dumps, mauling troop concentrations, and destroying approximately 350 bunkers on Heartbreak and in the surrounding hills and valleys. A smaller tank-infantry team scoured the Sat'ae-ri Valley east of the ridge, thereby completing the encirclement and eliminating any hope of reinforcement for the beleaguered North Koreans on Heartbreak.

The armored thrusts turned the tide of the battle, but plenty of hard fighting remained for the infantry before French soldiers captured the last communist bastion on the ridge on October 13. After 30 days of combat, the Americans and French eventually gained the upper hand and secured Heartbreak Ridge.

Both sides suffered high casualties: over 3,700 American and French and an estimated 25,000 North Korean and Chinese. These losses made a deep impression on the U.N. and U.S. command, which decided that battles like Heartbreak Ridge were not worth the high cost in blood for the relatively small amount of terrain captured. For this reason, Heartbreak Ridge was the last major offensive conducted by U.N. forces in the war.

Sporadic battles along the line of contact between U.N. and communist forces continued to be fought until the armistice was signed in July 1953, but they were usually initiated by the North Koreans or Chinese.

Battle of Chipyong-ni

Chipyong-ni
  • Chipyong-ni was defended because the commanding general of Eighth Army (Lt. Gen. Matthew B. Ridgway) decided to make a stand there against the Chinese Communists.


In the chronology of Korean battles, the fighting for Chipyong-ni followed the withdrawal from northern Korea at the end of 1950, a brief Eighth Army offensive that began on 5 February 1951, and a full-scale Chinese counteroffensive that struck a week later.

The 23d Regimental Combat Team made the decisive defense of Chipyong-ni on 13 and 14 February 1951. This action followed the patrol ambush and the subsequent battle for the Twin Tunnels area some high ground three miles southeast of Chipyong-ni. After the Twin Tunnels operation, the 23d Infantry Regiment (2d Infantry Division) proceeded on the afternoon of 3 February to the town of Chipyong-ni and set up a perimeter defense. Chipyong-ni was a small crossroads town half a mile long and several blocks wide, situated on a single-track railroad. Besides the railway station there were several other brick or frame buildings in the center of the town, but most of the buildings were constructed of the usual mud, sticks, and straw. At least half of the buildings were already reduced to rubble as the result of previous fighting in the town.

Encircling Chipyong-ni were eight prominent hills that rose to an average height of 850 feet above the rice paddies and buildings in the valley. These hills provided excellent defensive positions, but to have occupied them would have stretched the front-line defensive positions along 12 miles of ridgelines and formed a perimeter with a 3- to 4-mile diameter. Instead, the regimental commander (Col. Paul L. Freeman) stationed his infantrymen on lower ground around a tight perimeter about a mile in diameter. On three sides of the town the line followed small hills; on the northwest section the infantrymen dug their holes across a half-mile strip of rice paddies.

During the ten days after going into position at Chipyong-ni, Colonel Freeman's regiment dug in and strengthened its positions. The 37th Field Artillery Battalion (attached to the regiment) arrived on 5 February. Battery B, 82d Antiaircraft Artillery Automatic Weapons Battalion, joined the regiment, adding six M16 and four M19 flakwagons to the defense of the town. Several days later Battery B, 503d Field Artillery Battalion (a 155-mm howitzer unit), was attached to reinforce the fires of the 37th Field Artillery Battalion.

The infantry companies dug in their machine guns, registered their mortars, sowed antipersonnel mines, and operated daily patrols to the encompassing high ground. The regimental Heavy-Mortar Company divided he fires of its platoons and sections among the sectors of the perimeter, the artillery registered on all probable avenues of enemy approach, and all units established good communications lines. There was time to coordinate the infantry, artillery, and air support into an effective combat team.

This narrative describes the fighting for Chipyong-ni that occurred in that sector of the 2d Battalion's perimeter defended by Company G, 23d Infantry. As it happened, the howitzers of Battery B, 503d Field Artillery Battalion, were in position at the bottom of Company G's hill so that the artillerymen were drawn into the same battle. The commander of the 2d Battalion (Lt.Col. James W. Edwards) placed all three of his rifle companies on the front line to cover the sector assigned to his battalion. This was the south rim of the perimeter. Within the companies, two company commanders committed their three rifle platoons. The other company (F), to which Colonel Edwards assigned the center and smallest sector, manned its part of the line with only two platoons, leaving its support platoon as the battalion reserve.

The narrow supply road leading southwest from Chipyong-ni went under the railroad on the south edge of the town and then, within a third of a mile, passed two embankments of red clay where the road cut through the two ends of a U-shaped hill. Company G started at the second of these two road cuts and extended left (east) along the southern side of the U. It was not much of a hill only a couple of contour lines on the map. Infantrymen could climb the smooth hump of earth in a few minutes. The 1st Platoon of Company G held the right end of the hill next to the road cut. The 3d Platoon had the center position (the highest part of the hill) and extended its line left to the bend of the U. The 2d Platoon was down in the rice paddies between the 3d Platoon and Company F.

Men from the two platoons on the hill dug their holes just over the top of the forward slope. The positions restricted the fields of fire somewhat but provided good observation, especially for the 3d Platoon, which could see all areas to the south except for a dead spot in a dry creek bed just in front of its right flank.

There were two other significant features near the 3d Platoon's area.

At the foot of the hill and just beyond the dry creek bed was a cluster of 15 or 20 buildings that made up the village of Masan. The second feature was a narrow spur of ground that formed a link between the 3d Platoon's hill and a large hill mass to the south. The 2d Platoon in the rice paddies lacked satisfactory observation but had good fields of fire across the flat land to its immediate front.

In addition to its own Weapons Platoon, Company G's supporting weapons included a section of 75-mm recoilless rifles, a section of heavy machine guns from Company H, and a platoon of 88-mm mortars which was dug in near the edge of the town and had a forward observer stationed with Company G. There were also forward observers from the regimental Heavy-Mortar Company and from the 37th Field Artillery Battalion with Company G. During the daytime men from the 75-mm recoilless rifle section manned their weapons, but at night they replaced them with two caliber .50 machine guns to prevent having their positions disclosed at night by the back-blasts of the recoilless rifles.

The Ammunition and Pioneer Platoon set up two fougasses (drums of napalm)

, the first on the road just south of the road cut, and the second in the rice paddies in front of the 2d Platoon. The 1st Platoon, which was next to the road, also strung barbed-wire entanglements across the road and in front of its position. There was not enough wire available to reach across the company front. Colonel Edwards supervised the siting of all weapons, and the digging of the holes which he insisted be of the standing type and deep enough for good cover.

When Battery B, 503d Field Artillery Battalion, arrived, its 155-mm howitzers went into position in the small bowl formed by the U-shaped ridge of which Company G occupied one side. The howitzers were laid by platoon to support the east, north, and west sectors of the regimental perimeter. To the rear of the howitzers, the artillerymen set up a tent for the fire direction center (FDC) personnel. Behind that, near the bottom of Company G's hill, were several other tents for the mess and supply sections. A liaison officer from the 37th Field Artillery Battalion to Battery B (Capt. John A. Elledge), and the commander of Company G (Lt. Thomas Heath) worked out a plan for joint defense of the sector. This plan provided for the use of the artillery's machine guns on the front line and, if necessary, the use of some artillerymen as riflemen while skeleton crews manned the howitzers. The two officers also set up an infantry-artillery machine-gun post in the road cut with a six-man crew to operate two machine guns one caliber .50 and one caliber .30. This road cut was also the dividing line between Colonel Edwards's 2d Battalion sector and that of the French Battalion (a regular battalion of the 23d Infantry).

In the meantime, while the 23d RCT built up its defenses, an Eighth Army general offensive got under way on 5 February with X Corps, in the center of the line, attacking to make a double envelopment of the town of Hongchon, an important enemy build-up area. The attack moved slowly until the night of 11 February, when the Chinese launched a full-scale counteroffensive with two columns driving south aimed at the towns of Hoengsong and Wonju in X Corps' sector. The vigorous enemy attack drove through two ROK divisions and turned the United Nations' attack into a withdrawal that rolled the front lines south between 5 and 20 miles. Before the Chinese attack, the front lines of X Corps were well ahead of Colonel Freeman's Chipyong-ni perimeter, but as the units went south, sometimes fighting through enemy roadblocks, Chipyong-ni became a conspicuous bulge on the left of the corps' line.

At the 23d Infantry's perimeter, the usual patrols for the daylight hours of 13 February reported increased enemy activity crowding close to Chipyong-ni on three sides north, east, and west. The Air Force observation plane operating with the RCT reported enemy groups moving toward the perimeter from the north and east. Observers called for artillery fire against those enemy columns within reach, while the tactical air control party directed forty flights of aircraft against other enemy groups beyond artillery range. Tomahawks, We Serve.

1st Battalion, 23rd Infantry Regiment

The unit derived from the 4th Battalion, 8th Infantry regiment, 1st Armored Div, which served in Manheim, Germany until the unit was sent (along with the rest of the brigade) to Fort Lewis, Washington in the summer of 1994. That fall, the regiment was inactivated and re-designated 1st Battalion, 23rd Infantry regiment, 2nd Infantry Division. This enabled the first time units of the 2nd Inf. Division set foot on US soil since The Korean War began.

Here they began the establishment of a company Combat Outpost that would be known as Sangar, as well as the inception of COIN operations designed to provide security to the populace. Company B remained at FOB Wolverine with the battalion headquarters, and began conducting operations in Surri, which is a subdistrict of Shinkay.

, with the exception of Company C, who experienced a suicide attack in the Shajoy Bazaar which wounded 15 US Soldiers and one interpreter. The first battalion mission planned was Operation Longview, which encompassed multiple clearing operations in the Zabul Province intended at keeping the enemy from establishing a firm foothold in several key locations. Once Ramadan ended, the enemy became more aggressive, especially in Surri. Company B met the enemy several times in “the football”, the area between Route Duck and Route Bull, to include the second in command of Taliban fighters in Zabul Province, Mohammad Khan. Khan set an ambush near the village of Mado, but was wounded in the fight and forced to flee. Intelligence reports later confirmed that Mohammad Khan had been killed in the engagement. The Taliban sought vengeance for their loss, and stepped up their attacks on coalition forces. On September 24, Company B struck a pressure plate ied

 near the town of Omar Zai, which killed three US Soldiers and wounded three others. This incident led the battalion to adopt a more enemy-focused mission, and was the impetus behind Operation Laconia, the clearing of Omar Zai, Gazak Kalay, Bowlan Kalay, Patukheyl Kalay and Melizay Kalay. This operation, partnered with the ANA, led to the discovery of two IED caches and the disruption of the IED cell operating southwest of FOB Wolverine.

In October, as part of Operation Longview, Company A conducted Operation Treadstone: a partnered clearing of the Rowghani, Band Kalay, and Karim Khel areas north of Shinkay. Company C conducted Operation Chinehs: a battalion minus clearing of the Chinehs area north of Shajoy, known as the home of the shadow governor of Zabul. This mission yielded several IED caches, as well as the discovery of a madrassa where young men were trained to be suicide bombers. In November, 4-23 IN’s sister battalion, 1-17 IN, suffered the loss of seven Soldiers in an IED strike in the Arghandab River Valley in Kandahar Province. This incident led to the Brigade minus mission Operation Focus Hold, where B/4-23 was ordered to move from FOB Wolverine to COP Jelawar in the southern Arghandab in order to assist 1-17 IN. Company C continued building COP Sangar and conducting patrols in Shajoy, until November 19 when a VBIED struck the joint ECP of COP Sangar and FOB Bullard, killing two paratroopers from the 1-508th PIR. This led to the reestablishment of Operation Las Cruces: the tightened control of Shajoy City that occurred between 20–24 November, as well as the arrival of engineers and materials for the improvement of force protection on the COP. While 4-23 IN Soldiers were enjoying turkey meals for Thanksgiving dinner at their respective bases, RC South was preparing a FRAGO for 5/2 SBCT. On 6 December, the Brigade would receive a change of mission to stop COIN operations in their battle spaces and focus on securing freedom of movement on the highways of southern Afghanistan. As part of this, 4-23 IN was to move out of Zabul Province and occupy bases in Helmand

 Province, in order to provide security on Highways 1 and 601. The battalion commander gave the order to consolidate all units at FOB Wolverine and prepare for movement. Company A was the first element to leave Zabul, moving into FOB Ramrod in the Maiwand District of Kandahar Province, alongside 2-1 IN. They began their area assessments of their new AO along HWY 601 from Durai Junction to Lashkar Gah. Company B was released from 1-17 IN on 28 December and moved to FOB Tombstone, from which they would begin operations along Highway 1 west of the city of Gereshk. The battalion Headquarters and Company C were last to move, occupying FOB Price, a joint Danish, British, and American base outside the city of Gereshk

, in Helmand Province. The expansion of FOB Price required a large scale logistical move of building materials and life support equipment in order to establish the operations center, motor pool, ANA training academy, living areas, and security towers. By the time it was completed, FOB Price grew to over twice the size it had been originally. Company C picked up its sector, responsible for Highway 1 between Gereshk and Durai Junction. Headquarters Company, which had previously owned battle space in Zabul, instead supervised the creation of the Mohawk Academy, which began the training of Afghan National Army Soldiers in basic skills such as first aid and marksmanship.

Upon arriving in Helmand Province, the battalion, partnered with 6/4/205 ANA and the Lashkar Gah ANP, executed Operation Helmand Sunrise, which focused on securing the highways by means of Traffic Control Points, culvert denial emplacement, persistent surveillance, and training of the ANA and ANP along HWY 1 and HWY 601.

: the clearing of the known Taliban stronghold in central Helmand Province known as Marjeh. 4-23 IN was chosen to participate in this operation. The battalion leadership met Marine commanders at FOB Dwyer as early as 20 January to create a plan for the clearing of Marjeh, specifically focusing on the battalion’s role in clearing the Badula Qulp area along the Trekh Zabur Canal, which would be known as Operation Helmand Spider. 5/2 SBCT would attach A/1-17 IN to 4-23 IN for the operation, while B/1-17 IN would occupy FOB Tombstone and pick up operations in the B/4-23 IN sector while they were participating in Operation Moshtarak, as continued presence on the highways was deemed critical to mission success. Operation Helmand Spider began February 8 and lasted for 26 days. Task Force Mohawk, partnered with 1/1/205 ANA, cleared south along the Trekh Zabur Canal, conducting a link up with 3/6 Marines at the “5 points” intersection in southern Nad-e Ali District. Following this, A/1-17 IN and B/4-23 IN pushed west into northern Marjeh to conduct disruption operations, while the Reconnaissance Platoon conducted screening along the northern corridor in order to prevent the infiltration of Taliban reinforcements. Task Force Mohawk continued operations until 6 March, when they were relieved by elements of 3/6 Marines. In the month long operation, the task force had 15 enemy KIA, 9 enemy WIA, 23 IEDs found and cleared, 8 IED strikes, and 497 individuals enrolled in biometric systems. 4-23 IN and its supporting elements were recommended by Task Force Leatherneck for a Presidential Unit Citation for their actions in Marjeh. During the month of February, several smaller company operations were conducted along HWY 601 and in the Yakhchal valley. Company A conducted Operation 601 Cougar, clearing north through Gavban in the southern Yakhchal, which yielded a great amount of intelligence about the enemy in the area. Company C conducted missions in Mohammad Karim Kalay, as well as Yakhchal, in order to disrupt enemy forces influencing HWY 1. Throughout the remainder of the deployment, 4-23 IN continued to provide freedom of movement along the highways, while simultaneously planning to hand over their vehicles and equipment to 2d Stryker Cavalry Regiment, and hand over the Helmand battlespace to the 2d Marine Expeditionary Brigade and the Danish Battlegroup. The final battalion operation was the move back to Zabul Province in order to set up operations for 2d Stryker Cavalry Regiment to assume responsibility.

4-23 IN returned to Fort Lewis in July 2010 following a 12 month deployment in support of Operation Enduring Freedom. The battalion was part of the first Stryker unit to ever deploy to Afghanistan. 4-23 IN was the only Stryker battalion operating in the remote, mountainous terrain of Zabul Province, which required greater logistical coordination, maintenance, and care of equipment than any other unit. The battalion was the only infantry unit in Afghanistan to be tasked to move across two provinces and set up operations in an entirely new area. 4-23 IN was the only U.S. Army unit to take part in Operation Moshtarak, the largest offensive operation in Afghanistan since the war began in 2001. 4-23 IN was also the only U.S. Army Infantry battalion operating in the volatile Helmand Province. 4-23 IN as part of 5th Stryker Brigade, 2ND Infantry Division was the second U.S. Army Brigade to deploy with the Landwarrior system.
