CHAPTER XVIII

The Foundation of Freedom is the Courage of Ordinary People

History  Bert '53  On Line



Back to Ebb And Flow

Advance to the Parallel

As a first step in the attempt to block and attack the North Korean I Corps, Ridgway on 21 March ordered his own I Corps to move forward to line Cairo, which he extended southwestward across General Milburn's zone through Uijongbu to the vicinity of Haengju on the Han. (Map 28) At points generally along this line six to ten miles north of line Lincoln Milburn's patrols had made some contact with the North Korean I Corps west of Uijongbu and the Chinese 26th Army to the east. Milburn was to occupy line Cairo on 22 March, a day ahead of the airborne landing at Munsan-ni, and wait for Ridgway's further order to continue north.1

Requiring Milburn to stand along line Cairo unless instructed to proceed stemmed from Ridgway's not yet having given the final green light to the airborne landing as of the 21st. Operation TOMAHAWK, as the landing was called, would take place only if Ridgway received assurances that weather conditions on 23 March would favor a parachute drop and that ground troops could link up with the airborne force within twenty-four hours. If these assurances were forthcoming, the 187th Airborne Regimental Combat Team, with the 2d and 4th Ranger Companies attached, was to drop in the Munsan-ni area on the morning of the 23d and block Route 1. Milburn was to establish physical contact with and assume control of the airborne force once it was on the ground. At the same time, he was to open a general corps advance toward line Aspen, which traced the lower bank of the Imjin River west and north of Munsan-ni, then sloped eastward across the corps zone to cut Routes 33 and 3 eight miles north of Uijongbu. Once on Aspen, Milburn was to expect Ridgway's order to continue to line Benton, the final COURAGEOUS objective line, some ten miles farther north. Reaching Benton would carry the I Corps virtually to the 38th parallel except in the west where the final line fell off to the southwest along the Imjin.2

Because the I Corps otherwise would have an open east flank when it moved to line Benton, Ridgway extended the line southeastward into the IX Corps zone across the front of the 24th Division and about halfway across the front of the ROK 6th Division to a juncture with line Cairo. When Ridgway ordered the I Corps to Benton, General Hoge was to send his western forces to the line to protect the I Corps flank. Meanwhile, in concert with Milburn's drive to lines Cairo and Aspen, Hoge was to complete the occupation of his sector of line Cairo. Elsewhere along the army front, the X Corps and the ROK III and I Corps remained under Ridgway's order of 18 March to reconnoiter the area between the Hwach'on Reservoir and the east coast. As yet, neither Almond's patrols nor those of the South Korean corps had moved that deeply into enemy territory.3

The three divisions of the I Corps started toward line Cairo at 0800 on 22 March. The ROK 1st Division, advancing astride Route 1 in the west, overcame very light resistance and had troops on the phase line by noon. The 3d Division astride Route 3 in the center and the 25th Division on the right also met sporadic opposition but moved slowly and ended the day considerably short of the line.4

General Milburn meanwhile assembled an armored task force in Seoul for a drive up Route 1 to make the initial contact with the 187th Airborne Regimental Combat Team if and after it dropped on Munsan-ni. Building the force around the 6th Medium Tank Battalion borrowed from the 24th Division of the IX Corps, he added the 2d Battalion, 7th Infantry, and all but one battery of the 58th Armored Field Artillery Battalion from the 3d Division; from corps troops he supplied a battery of the 999th Armored Field Artillery Battalion and Company A, 14th Engineer Combat Battalion. He also included two bridgelaying Churchill tanks from the 29th British Brigade, recently attached to the I Corps. Lt. Col. John S. Growdon, commander of the 6th Medium Tank Battalion, was to lead the task force.5

Ridgway made the final decision on the airborne operation late in the afternoon of the 22d during a conference at Eighth Army main headquarters in Taegu. General Partridge, the Fifth Air Force commander, assured him that the weather would be satisfactory on the 23d; Col. Gilman C. Mudgett, the new Eighth Army G-3, predicted not only that contact with the airborne unit would be made within a day's time, as Ridgway required, but that the entire I Corps should be able to advance rapidly.6 Given these reports, Ridgway ordered the airborne landing to take place at 0900 on the following day.7

On hearing the final word on the Munsan-ni drop, General Milburn directed Task Force Growdon to pass through the ROK 1st Division on line Cairo early on 23 March and proceed via Route 1 to reach the airborne troops. His three divisions meanwhile were to resume their advance with the objective of reaching line Aspen. The ROK 1st Division, which would be following Task Force Growdon, was to relieve the 187th Airborne Regimental Combat Team upon reaching Munsan-ni, and the airborne unit then was to prepare to move south and revert to Eighth Army reserve.8

Task Force Growdon, completely motorized, passed through the ROK 1st Division shortly after 0700. No enemy forces opposed the armored column as it moved ahead of the South Koreans, but within minutes the third tank in column hit a mine while bypassing a destroyed bridge at the small Changnung River. The task force was held up while engineers removed a dozen other mines from the bypass. Proceeding slowly from that point with a mine detector team leading the way afoot, Colonel Growdon's column moved only a mile to the village of Sinwon-ni before encountering more mines. As the 187th Airborne Regimental Combat Team began landing at Munsan-ni at 0900, Growdon's task force was at a halt some fifteen miles to the south.9

C-46s and C-119s of the 315th Air Division had begun lifting the airborne troops from the Taegu airfield shortly after 0700, all heading initially for a rendezvous point over the Yellow Sea west of the objective area.10 The second serial of aircraft, with the 1st Battalion of the 187th aboard, was in flight only briefly before engine trouble in the lead plane forced the pilot to return to Taegu for a replacement aircraft. The combat team landed before the new lead plane, whose passengers included the 1st Battalion commander, could reach Munsan-ni. The drop, as a result, did not come off entirely as planned.11

General Bowen, commander of the 187th, had designated two drop zones, one about a mile northeast of Munsan-ni, another about three miles southeast of town. The 1st Battalion was to land in the lower zone, the remainder of the combat team in the one to the north. 12 As planned, the 3d Battalion with the 4th Ranger Company attached jumped first, Bowen having given it the mission of securing the northern drop zone. Bowen's plan went awry when the leaderless second serial of planes mistakenly followed the first and dropped the 1st Battalion also in the northern zone. The 2d Battalion with the 2d Ranger Company attached followed not long after, then the 674th Airborne Field Artillery Battalion, and at 1000 the artillery heavy drop.13

In the brief interval between the drops of the 1st and 2d Battalions, General Ridgway arrived by L-19, landing on a road between Munsan-ni and the northern drop zone. En route, he had flown over Task Force Growdon then held up at Sinwon-ni, a fact he passed to General Bowen. Airborne again shortly after 1000, Ridgway saw a single stick of paratroops jump from a plane over the lower drop zone. The replacement plane carrying the 1st Battalion commander and party had finally reached Munsan-ni, and its passengers had jumped in the correct zone not knowing that they would be the only troops in the area.14

To the north, resistance in and immediately around the drop zone was minor and sporadic, amounting to a few small groups of North Koreans and a meager amount of fire from mortars located somewhere to the north. Overcrowding caused by the 1st Battalion's misdirected drop complicated the 3d Battalion's assembly, but units managed to sort themselves out and secure the borders of the drop zone. An unexpected annoyance was created by civilians who appeared in the drop zone and began carrying away parachutes. Shots fired over their heads ended the attempted theft. Against moderate but scattered opposition the 2d Battalion proceeded to occupy heights northeast of the drop zone, and under the command of its executive officer the 1st Battalion, less Company B, moved into the ground to the north and northwest, clearing Munsan-ni itself in the process.15

Company B went on a rescue mission to the southern drop zone after learning that the command group of the 1st Battalion had come under fire from enemy forces on Hill 216 overlooking the drop zone from the northwest. Company B forced the enemy group off the hill, allowing its survivors to withdraw to the southwest, and reached the drop zone by 1500. The rescue force and the battalion command group arrived at the regimental position to the north about two hours later. By that time Bowen's forces had secured all assigned objectives.16

Battle casualties among the airborne troops were light, totaling nineteen. Jump casualties were higher- eight-four- but almost half of these returned to duty immediately after treatment.

Enemy casualties included 136 dead counted on the field and 149 taken captive. Estimated enemy losses raised the total considerably higher. Prisoner interrogation indicated that the enemy forces who had been in the objective area were from the 36th Regiment of the North Korean 19th Division and had numbered between three hundred and five hundred. Most of the remainder of the North Korean I Corps apparently had withdrawn above the Imjin well before the airborne landing.17

The point of Task Force Growdon reached Munsan-ni at 1830 on the 23d, but the remainder of the extended column took several hours longer. The force encountered no enemy positions along Route 1 but was kept to an intermittent crawl by having to lift or explode over a hundred fifty live mines, some of them booby-trapped, and almost as many dummy mines, including a five-mile stretch of buried C-ration and beer cans. Casualties were few, but four tanks were disabled by mines. As the last of these tanks hit a mine a mile below Munsan-ni, the explosion attracted enemy artillery fire that damaged two more. The tail of the task force finally arrived at the airborne position at 0700 on 24 March.18

General Milburn's orders to the 187th for operations on the 24th called only for patrolling. Having been given control of Task Force Growdon by Milburn, General Bowen built his principal patrols around Growdon's tanks and sent them to investigate ferry sites on the lmjin and to check Route 2Y, an earthen road running east from Munsanni, as far as the village of Sinch'on, ten miles away. One patrol made contact while checking an lmjin ferry site and ford ten miles northeast of Munsan-ni. Six enemy were killed and twenty-two captured. The patrol suffered no casualties, but a tank had to be destroyed after it bogged down at a stream crossing while approaching the lmjin. A few rounds of artillery fire meanwhile fell in the northern drop zone but caused no casualties.19

The ROK 1st Division in the meantime had advanced steadily toward Munsan-ni without enemy contact. Early on the 24th Task Force Boone, a division armored column consisting of Company C, 64th Tank Battalion (on loan to General Paik from the 3d Division), Paik's tank destroyer battalion (organized as an infantry unit), and two of his engineer platoons, stepped ahead of the division and reached the 187th Airborne Regimental Combat Team at midmorning. By day's end the remainder of the division occupied a line extending from positions athwart Route 1 about three miles below Munsan-ni northeastward to Pobwon-ni, a village on lateral Route 2Y six miles east of Munsan-ni area. General Paik relieved General Bowen of responsibility for the Munsan-ni area at 1700 and placed Task Force Boone in position just above the town.20

The lack of resistance to the wider sweep of the ROK 1st Division's advance confirmed that the bid to block and attack the North Korean I Corps had been futile. To the east, that the Chinese 26th Army still had forces deployed to delay the advance of the 3d and 25th Divisions had become equally clear. On the I Corps right, the 25th Division on 23 and 24 March had run into a large number of minefields and small but well entrenched enemy groups employing small arms, machine gun, and mortar fire. At nightfall on the 24th General Bradley's forces held positions almost due west of Uijongbu in the 3d Division's zone at corps center.21

Somewhat unexpectedly, the 3d Division had come up against unusually strong Chinese positions. On 23 March General Soule's forces had occupied the Uijongbu area with little difficulty. First to enter the town itself was Task Force Hawkins, built around the bulk of the 64th Tank Battalion and two platoons of tanks from each of the 15th and 65th Infantry Regiments. Reaching Uijongbu about 0900 and finding it undefended, the task force reconnoitered north several miles on Route 33 before returning to the division position. Mines disabled two tanks, but otherwise the task force made no contact.22

Though it thus appeared that the 3d Division could continue to move forward with relative ease, General Soule's forces came under heavy lire when they resumed their attack on the morning of the 24th. The Chinese had organized strong positions in the Hill 468 mass rising three miles northwest of Uijongbu and the 337 mass about a mile north and slightly east of town. From these positions they were in fair condition to block advance on the Route 33 axis to the north and over Route 3 leading out of Uijongbu to the northeast. On the division's right, the 15th Infantry eventually managed to clear Hill 337 on the 24th, but the 65th Infantry on the left failed in an all-day attempt to force the Chinese from the 468 mass.23

General Milburn viewed the situation at corps center as an opportunity to trap and destroy the Chinese holding up the 3d Division. After General Soule's forces encountered the strong enemy positions on the morning of the 24th, he ordered General Bowen to pull in his patrols and prepare the 187th Airborne Regimental Combat Team for an eastward attack on the Route 2Y axis. The objective was high ground abutting Route 33 about ten miles north of Uijongbu, thus just above the trace of line Aspen, whence Bowen was to prevent the Chinese in front of the 3d Division from withdrawing over Route 33. The 3d Division was to continue its northward attack in the meantime and eventually drive the Chinese against Bowen's position.24

General Bowen started east at 1800, intending to march as far as Sinch'on during the night and open his attack the following morning. From Task Force Growdon, Company C was the only unit of the 6th Tank Battalion able to move at 1800; all other companies of the battalion had too little fuel after patrolling and were to catch up with Bowen's column after being resupplied from Seoul. The Growdon force now also was short the 2d Battalion, 7th Infantry, which had been sent back to the 3d Division.25

A force shaped around the tanks of Company C led the way toward Sinch'on. But after seven miles, as Bowen's column moved through a system of ridges, landslides in defiles twice trapped the leading tanks, and in the second instance no bypass could be found. As engineers tried to open the road, rain began to fall and became steadily heavier. With the rain making a poor road even worse, Bowen ordered the tanks back to Munsan-ni. After the engineers had cleared the road sufficiently, his remaining forces proceeded to Sinch'on, arriving about 0600 on the 25th.26

A half hour later Bowen ordered the 2d Battalion, with the 3d Battalion following in support, to seize Hill 228 rising on the west side of Route 33. Running into small arms, machine gun, and mortar fire from enemy positions on several nearer heights and hampered by a continuing driving rain, the two battalions at day's end were some two miles short of Hill 228, and Route 33 remained available to the Chinese in front of the 3d Division if they chose to withdraw over it.27

Withdrawal seemed to be the Chinese intention. The 3d Division met only light resistance when it resumed its attack from the south on the 25th and advanced two miles beyond the hill masses where strong Chinese positions had delayed it the day before. The tank company of the 65th Infantry meanwhile moved ahead on Route 3X, a secondary road angling northwest off Route 33 to Sinch'on, in an attempt to contact the 187th Airborne Regimental Combat Team. Mines along the road disabled four tanks and kept the company from reaching its destination, but it encountered no enemy positions. The withdrawal of the Chinese delaying forces was confirmed on the 26th when the 3d Division and the 25th Division as well moved forward against little or no opposition.28

To the north, the Chinese continued to oppose the efforts of the 187th Airborne Regimental Combat Team to capture Hill 228. Using Route 33 and a lesser road to the west, two tank columns from the 3d Division joined Bowen's forces during the afternoon of the 26th, but, even with armored support, it was 0900 the following day before the 187th captured Hill 228.29 Using the remainder of the 27th for reorganization and resupply, General Bowen attacked the heights on the east side of Route 33 early on 28 March and occupied them after an all-day battle to eliminate stiff enemy resistance.30

The 15th and 65th Infantry Regiments of the 3d Division meanwhile reached the airborne forces, the 1st Battalion of the 15th Infantry making first contact late in the afternoon of the 27th. Despite General Milburn's hopes for the operation, the two regiments drove no enemy forces into the guns of the airborne unit. Either the Chinese resisting the eastward attack of the 187th had kept Route 33 open long enough for the forces withdrawing before the 3d Division to pass north, or the withdrawing enemy units had used another road, perhaps Route 3. Moving through spotty resistance, the 25th Division on the right had kept pace with the 3d Division, and by nightfall on 28 March both were on or above line Aspen.31

Riper Concluded

Late on 26 March, as it became obvious that the Chinese were backing away from the 3d and 25th Divisions, General Ridgway had ordered the I and IX Corps to continue to line Benton. As originally conceived, the IX Corps advance to Benton was limited to General Hoge's western forces and was intended simply to protect the I Corps' right flank. But Ridgway had since modified his plan of operations, widening the advance to include the entire IX Corps and all other forces to the east.32

On 23 March he had lengthened line Benton eastward through the 1st Cavalry Division's patrol base at Ch'unch'on and as far as the 1st Marine Division's zone on the IX Corps right, where it joined the last few miles of line Cairo. On the following day he had extended line Cairo from its original terminus in the Marine zone northeastward across the remainder of the army front to the town of Chosan-ni on the east coast.33 The final objective line of the RIPPER operation thus had become a combination of the Benton and Cairo lines following the upstream trace of the Imjin virtually to the 38th parallel in the west, hanging slack a few miles below the parallel for almost all of its remaining length to the east, then rising to an east coast anchor some eight mile above the parallel. (See Maps 26 and 27.)

Ridgway's forces achieved the adjusted line by the end of March, encountering no more than the sporadic delaying action that had characterized the opposition to Operation RIPPER from the outset. Thus, since 7 March Eighth Army forces had made impressive territorial gains, recapturing the South Korean capital and moving between twenty-five and thirty miles north to reach-or all but reach-the 38th parallel. Estimates of enemy killed and wounded during the month were high, and some forty-eight hundred Chinese and North Koreans had been captured. Nevertheless, the results in terms of enemy troops and supplies destroyed were considerably less than anticipated. The clear fact was that the enemy high command had been and still was marshaling its main forces beyond the reach of the RIPPER operation. Equally obvious was that only advances above the 38th parallel could attack these main forces.34

The Parallel Question

Earlier, as General Ridgway was about to open Operation COURAGEOUS, the gains he already had registered in his KILLER and RIPPER advances had influenced a decision in Washington by which operations above the parallel assumed new importance as a political question. The decision centered on how and when to approach the desired ceasefire. Notwithstanding the building evidence of enemy offensive preparations, officials of the Departments of State and Defense believed that Ridgway's recent successes might have convinced the Chinese and North Koreans that they could not win a military victory and, if this was the case, that they might agree to negotiate an end to hostilities. On the advice of these officials, President Truman planned to make a public statement suggesting the United Nations' willingness to end the fighting. The statement was carefully worded to avoid a threatening tone and so to encourage a favorable reply. Truman intended to deliver the appeal as soon as his statement had been approved by officials of all nations that had contributed forces to the U.N. Command.35

The timing of the presidential announcement was tied also to the fact that Ridgway's forces were fast approaching the 38th parallel. The consensus in Washington was that the Chinese and North Koreans would be more inclined to agree to a cease-fire under conditions restoring the status quo ante bellum, that is, if the fighting could be ended in the vicinity of the parallel where it had begun. Therefore, while there was no intention to forbid all ground action above the parallel, there was some question in the mind of Secretary of State Acheson and among many members of the United Nations whether the Eighth Army should make a general advance into North Korea.36

The Joint Chiefs of Staff notified General MacArthur of the president's plan in a message radioed from Washington on 20 March. They informed him of the prevalent feeling in the United Nations that the U.N. Command should make no major advance above the 38th parallel before the presidential appeal was delivered and the reactions to it determined. They also asked for his recommendations on how much freedom of ground action UNC forces should have in the vicinity of the parallel during the diplomatic effort to provide for their security and to allow them to maintain contact with the enemy.37

MacArthur, of course, had been pressing Washington for decisions favoring a military, not a diplomatic, solution to the war. Shortly before he received the joint Chiefs' message he again had expressed his views in a letter to Republican Congressman Joseph W. Martin of Massachusetts, the-minority leader in the House of Representatives.38 The congressman earlier had written MacArthur asking for comment on Martin's thesis that Nationalist Chinese forces "might be employed in the opening of a second Asiatic front to relieve the pressure on our forces in Korea." MacArthur replied that his own view followed "the conventional pattern of meeting force with maximum counterforce," that Martin's suggestion on the use of Chiang Kai-shek's forces was in consonance with this pattern, and that there was "no substitute for victory."39

Although he had been denied the decisions that in his judgment favored a military solution, MacArthur nevertheless wanted no further restrictions placed on the operations of his command. In so advising the joint Chiefs on 21 March, he pointed out, as he had some time earlier, that under current conditions any appreciable UNC effort to clear North Korea already was out of the question.40

While awaiting a response, MacArthur informed General Ridgway of the new development on 22 March. Although MacArthur expected that the response from Washington would be a new directive for ground operations, possibly one forbidding an entry into North Korea in strength, he intended in the meantime to allow the Eighth Army to advance north of the parallel as far as logistics could support major operations. Ridgway otherwise was to be restricted only by having to obtain MacArthur's specific authorization before moving above the parallel in force.41

In acknowledging these conditions Ridgway notified MacArthur that he currently was developing plans for an advance that would carry Eighth Army forces ten to twenty miles above the parallel to a general line following the upstream trace of the Yesong River as far as Sibyon-ni in the west, falling off gently southeastward to the Hwach'on Reservoir, then running almost due east to the coast. As in past and current operations, the objective would be the destruction of enemy troops and materiel. MacArthur approved Ridgway's concept but also scheduled a visit to Korea for 24 March, when he would have an opportunity to discuss the plans in more detail.42

Before leaving Tokyo on the 24th, MacArthur issued a communique in which he offered to confer with his enemy counterpart on arranging a ceasefire. He specified that he was making the offer "within the area of my authority as the military commander" and that he would be in search of "any military means" for achieving the desired result. He thus kept the bid itself within the military sphere.43 But in leading up to his offer MacArthur belittled China's military power, noting in particular that Chinese forces could not win in Korea, and made statements that could be, and were, interpreted as threatening that the United Nations would decide to attack China if hostilities continued. These remarks prompted other governments to ask about a possible shift in U.S. policy, and in President Truman's judgment they so contradicted the tone of his own planned statement that he decided not to issue it for fear of creating more international confusion.44

MacArthur's announcement thoroughly angered the president. It was, he wrote a few days later, "not just a public disagreement over policy, but deliberate, premeditated sabotage of US and UN policy."45 Moreover, MacArthur had not cleared his communique with Washington as the president's directive of December 1950 required for all releases touching on national policy. Truman considered MacArthur's violation of the directive as "open defiance of my orders as President and as Commander in Chief."46 His immediate act was to order the Joint Chiefs of Staff to send MacArthur a reminder of the December directive. Privately, he decided that MacArthur should be relieved.47

Included in the reminder sent by the joint Chiefs on 24 March (received in Tokyo on the 25th) were orders that MacArthur report to them for instructions should his counterpart respond to his offer and "request an armistice in the field." No such response was expected, however, and since Truman had canceled his own cease-fire initiative, operations in strength above the 38th parallel again had become a tactical question for General MacArthur and General Ridgway to answer. MacArthur, in fact, publicly revealed his answer before he really knew that the diplomatic effort to achieve a cease-fire had been canceled. Upon his return to Tokyo late on 24 March following his conference with Ridgway and a visit to the front, he announced that he had directed the Eighth Army to cross the parallel "if and when its security makes it tactically advisable.48 More specifically than that, of course, MacArthur had approved Ridgway's concept of a general advance as deep as twenty miles into North Korea.

The Rugged and Dauntless Concept

In advance of issuing orders for attacks above the 38th parallel, General Ridgway assembled corps and division commanders at his Yoju headquarters on 27 March to discuss courses of action that were now open to them or that they might be obliged to follow. The possibility of Soviet intervention again had been raised, he told them. According to a reputable foreign source, the USSR planned to launch a large scale offensive in Korea near the end of April employing Soviet regulars of Mongolian extraction under the guise of volunteers. Ridgway doubted the accuracy of the report, but as a matter of prudence, since the Eighth Army might be ordered out of Korea in the event of Soviet intervention, he intended to pass the evacuation plan outlined by the Eighth Army staff in January to corps commanders for further development. Lest Eighth Army forces start "looking over the shoulder," no word of the course of action or preparations for it was to go beyond those working on the plan.49

Alluding to past and recent proposals of cease-fire negotiations, Ridgway also advised that future governmental decisions might compel the Eighth Army to adopt a static defense. Because of its inherent rigidity, such a stance would require strong leadership and imaginative tactical thinking, he warned, to stand off a numerically stronger enemy that might not be similarly inhibited in the choice of tactics.

The Eighth Army meanwhile would continue to move forward and in the next advance would cross the 38th parallel. Ridgway now agreed with General MacArthur's earlier prediction that a stalemate ultimately would develop on the battlefront, but just how far the Eighth Army would drive into North Korea before this occurred, he informed the assembled commanders, could not be accurately assessed at the moment.50

Ridgway had revised his concept for advancing above the parallel since meeting with MacArthur on 24 March. He originally had intended to direct a strong attack northwestward across the Imjin, expecting that in moving as far as the Yesong River the attack force would find the elusive North Korean I Corps. His intelligence staff later discovered that the bulk of the North Korean corps had withdrawn behind the Yesong and also warned that the attack force would be vulnerable to envelopment by a fresh Chinese unit located off the right flank of the advance. (The unit was the XIX Army Group, which intelligence had not yet fully identified.) Ridgway, as a result, elected to limit operations northwest of the Imjin to reconnaissance and combat patrols.51

He planned now to point his main attack toward the centrally located road and rail complex marked out by the towns of P'yonggang in the north and Ch'orwon and Kumhwa in the south.

This complex, eventually named the Iron Triangle by newsmen searching for a dramatic term, lay twenty to thirty miles above the 38th parallel in the diagonal corridor dividing the Taebaek Mountains into northern and southern ranges and containing the major road and rail links between the port of Wonsan in the northeast and Seoul in the southwest. Other routes emanating from the triangle of towns connected with Pyongyang to the northwest and with the western and eastern halves of the present front. A unique center of communications, the complex was of obvious importance to the ability of the enemy high command to move troops and supplies within the forward areas and to coordinate operations laterally.

Ridgway's first concern was to occupy ground that could serve as a base both for continuing the advance toward the complex and, in view of the enemy's evident offensive preparations, for developing a defensive position. The base selected, line Kansas, traced the lower bank of the Imjin in the west. From the Imjin eastward as far as the Hwach'on Reservoir the line lay two to six miles above the 38th parallel across the approaches to the Iron Triangle. Following the lower shoreline of the reservoir, it then turned slightly north to a depth of ten miles above the parallel before falling off southeastward to the Yangyang area on the coast. In the advance to line Kansas, designated Operation RUGGED, the I and IX Gores were to seize the segment of the line between the Imjin and the western edge of the Hwach'on Reservoir. To the east, the X Corps was to occupy the portion tracing the reservoir shore and reaching Route 24 in the Soyang River valley, and the ROK III and I Corps were to take the section between Route 24 and Yangyang.52

In anticipation of enemy offensive operations, Ridgway planned to pull substantial forces off the line immediately after reaching Kansas and prepare them for counterattacks. The IX Corps was to release the 1st Cavalry Division. Under army control, the division was to assemble at Kyongan-ni, below the Han southeast of Seoul, and prepare to meet enemy attacks aimed at the capital city via Route 1 from the northwest, over Routes 33 and 3 from the north, or through the Pukhan River valley from the northeast. In the X Gores zone, the bulk of the 2d Division was to assemble at Hongch'on ready to counter an attack following the Route 29 axis, and a division yet to be selected from one of the two ROK corps in the east was to assemble at Yuch'on-ni on Route 20 and prepare to operate against enemy attacks in either corps sector. The 187th Airborne Regimental Combat Team, which on 29 March left the I Corps zone for Taegu, meanwhile was to be ready to return north to reinforce operations wherever needed.53

While these forces established themselves in reserve, Ridgway planned to launch Operation DAUNTLESS, a limited advance toward the Iron Triangle by the I and IX Corps. With the objective only of menacing the triangle, not of investing it, the two corps were to attack in succession to lines Utah and Wyoming. They would create, in effect, a broad salient bulging above line Kansas between the Imjin and Hwach'on Reservoir and reaching prominent heights commanding the Ch'orwon-Kumhwa base of the communications complex. If struck by strong enemy attacks during or after the advance, the two corps were to return to the Kansas line.54

To maintain, and in some areas regain, contact with enemy forces, Ridgway allowed each corps to start toward line Kansas as it completed preparations. The RUGGED advance, as a result, staggered to a full start between 2 and 5 April. When General MacArthur made his customary appearance on the 3d, this time in the ROK I Corps zone on the east coast, Ridgway brought him up to date on plans. MacArthur agreed with the RUGGED and DAUNTLESS concept, urging in particular that Ridgway make a strong effort to hold the Kansas line. At the same time, MacArthur believed that the two operations would move the battlefront to that "point of theoretical stalemate" he had predicted in early March. He intended to limit offensive operations, once Ridgway's forces reached their Kansas-Wyoming objectives, to reconnaissance and combat patrols, none larger than a battalion.55

29 On the 26th General Soule reported to General Ridgway that one of his tanks had knocked out a T34. This piece was the first enemy armor destroyed by ground action since Ridgway had taken command of the Eighth Army. The T34 may have belonged to the 17th Mechanized Division of the North Korean I Corps. See Eighth Army CG SS Rpt, Nar, Mar 51.

38 The Tokyo dateline of MacArthur's letter was 20 March. Since Tokyo time is fourteen hours ahead of Washington time, MacArthur presumably wrote his letter before the joint Chiefs of Staff prepared their message of the same date.

43 To this extent, MacArthur's action was in accord with earlier advice a Department of State official gave the Department of Defense shortly after the Inch'on landing: "A cease-fire should be a purely military matter and . . . the Commanding General of the unified command . . . is the appropriate representative to negotiate any armistice or cease-fire agreement." See Schnabel, Policy and Direction, p. 359.

47 Ibid., pp. 442-43. When asked some years later why he did not relieve MacArthur at the time, Truman replied that he wanted a "better example of his insubordination, and I wanted it to be one . . . that everybody would recognize for exactly what it was, and I knew that, MacArthur being the kind of man he was, I wouldn't have long to wait."

50 The conference had a tragic postscript when the light plane returning General Kim, commander of the ROK I Corps, to Kangnung crashed in the Taebaeks, killing the general and his pilot. General Paik, the excellent leader of the ROK 1st Division, became the new commander of the ROK I Corps early in April and Brig. Gen. Kang Moon Bong took command of the 1st Division.
