The First and Second Battle of Wonju, also know as the Wonju Campaign or the Third Phase Campaign Eastern Sector[nb 4] (Chinese: 第三次战役东线; pinyin: Dì Sān Cì Zhàn Yì Dōng Xiàn), was a series of engagement between North Korean and UN forces during the Korean War. The battle took place from December 31, 1950 to January 20, 1951 around the South Korean town of Wonju. In coordination with the Chinese capture of Seoul on the Korean western front, the North Korean People's Army attempted to disrupt the road network near the Wonju area in an effort to destabilize the UN defenses along the central and the eastern front.
After a joint Chinese and North Korean attack breached the UN defenses at Chuncheon on the New Year Eve of 1951, the North Korean V Corps attacked the the US X Corps at Wonju while the North Korean II Corps harassed US X Corps' rear by engaging in guerrilla warfare. In response, the US X Corps under the command of Major General Edward Almond managed to cripple the North Korean forces at Wonju, and the UN forces later carried out numerous anti-guerrilla operations against the North Korean infiltrators. In the aftermath of the battle, the North Korean forces at the central and the eastern front were effectively decimated, allowing the UN front stabilized at the 37th parallel.
Background
[edit]After launching a surprise invasion against South Korea at June 1950, the North Korean People's Army (KPA) was completely shattered by the United Nations (UN) forces after the landing at Incheon at September 1950, with the remnants of the KPA fled northward while seeking sanctuaries along the mountainous regions at the Sino-Korean border.[5][6] The destruction of the KPA also prompted China to intervene in the Korean conflict, and Chinese forces soon launched a series of surprise attacks against the UN forces near the Sino-Korean border at the end of 1950.[7] The resulting battles at the Ch'ongch'on River Valley and the Chosin Reservoir forced the UN forces to retreat back to the 38th parallel by December 1950.[8] On the Korean eastern front, the US X Corps was trapped at the port of Hungnam near the Chosin Reservoir during the surprise Chinese offensive, and it was forced by to evacuate North Korea by sea on December 24, 1950.[9] In its absence, the Republic of Korea (ROK) Army was forced to take over the defenses of the central and the eastern fronts along the 38th parallel,[10] with the important road junction of Wonju located near the central front.[11] The sudden defeat of the UN forces offered the decimated KPA a brief respite, and the shattered North Korean forces soon rebuilt its strength at the end of 1950.[6]
In the aftermath of the Chinese successes, China's Chairman Mao Zedong immediately ordered another offensive against the UN forces on the urging of North Korean Premier Kim Il-sung.[12] The offensive, dubbed the "Third Phase Campaign", was a border intrusion into South Korea that envisioned the total destruction of South Korean forces along the 38th parallel,[13] and it was aimed at pressuring the UN forces to withdraw from the Korean Peninsula.[14] The western sector of the offensive was under the control of the Chinese People's Volunteer Army (PVA) 13th Army,[13][nb 1] and the 13th Army's action would later resulted in the capture of Seoul on January 4.[15] With the PVA 9th Army effectively decimated at the Chosin Reservoir, however, the eastern sector of the offensive was handed over to the rehabilitated KPA, under the overall command of Lieutenant General Kim Ung and Commissar Pak Il-u.[16] On December 23, 1950, General Walton Walker, commander of the US Eighth Army, died in a traffic accident, and Lieutenant General Matthew B. Ridgway assumed command of the Eighth Army on December 26, 1950.[17]
Prelude
[edit]Locations, terrain and weather
[edit]The battle's main focus was around a road dubbed the "Route 29", a strategically important line of communication to the UN forces in central Korea, and Wonju is a critical crossroad village on Route 29.[18] Running from north to south, the Route 29 connects Chuncheon on the 38th parallel with Daegu on the Pusan Perimeter.[11] Another road, which runs from the northwest, connects Route 29 and the South Korean capital of Seoul at Wonju.[11] Between Chuncheon and Wonju stands the town of Hoengseong, and from Wonju to Daegu are a series of towns such as as Chechon, Tanyang, Punggi and Andong.[11][19][20] The entire road network is situated within the rough hilly terrains of the Taebaek Mountain Range.[21]
The battles around Wonju was fought over some of the worst Korean winter conditions, with temperatures as low as −30 °F (−34 °C) and snow as thick 14 in (36 cm) on the ground.[22] The weather was so cold such that metals on artillery pieces would crack while water can took an hour and half to boil.[23] At times the cold weather alone is enough to stall all military activities, and the frostbite caused more casualties than combat during the course of the battle.[22]
Forces and strategy
[edit]Just days before his death, General Walker tried to defend to the central and the eastern section of the 38th parallel by stretching the South Korean forces from Chuncheon to the Korean east coast.[10] Following his instructions, the the ROK III Corps was placed around Chuncheon while the ROK I Corps was placed on the east coast.[10] The ROK 3rd Infantry Division, which became the infantry division that was under the control of ROK II Corps in the aftermath of the Ch'ongch'on River battle,[24] filled the gap between the ROK I and III corps.[10] But with the absence of the US X Corps, the UN defenses on the central and the eastern front were stretched thin, and there were gaps between the understrength South Korean units.[10][25] Because the South Korean forces had suffered nearly 45,000 casualties at the end of 1950,[26] most of the South Korean units were also composed of raw recruits with little combat training,[27] and out of the four South Korean divisions that defended Chuncheon, only one was deemed battle worthy.[28] Taking advantage of the situation, the North Korean forces had been probing the South Korean lines since mid-December, while thousands of North Korean guerrillas harassed the UN rear area from their mountains hideouts.[29] On December 27, 1950, the KPA II Corps managed to move behind the UN defenses by decimating the ROK 9th Infantry Division on the ROK I Corps' left flank at Hyon-ri, and this development threatened to destabilize the entire UN eastern front.[30][31]
To defend against the North Korean penetration, General Ridgway immediately ordered the US X Corps to reinforce the South Korean defenses.[21] But with most of the US X Corps still assembling at Pusan, the only units that was available in the Eighth Army's reserve was the US 2nd Infantry Division, which was still recovering from its earlier losses at the Ch'ongch'on River Valley.[28] On December 28, General Ridgway ordered the US 2nd Infantry Division to defend Wonju while transferring the division under US X Corps control.[32] After the US 7th Infantry Division of the US X Corps finished reorganization on December 30, Ridgway ordered Major General Edward Almond, commander of the US X Corps, to develop Route 29 the main X Corps supply route, and the 7th Infantry Division was tasked with defending Route 29.[33]
In coordination with the Chinese assaults against Seoul on the western sector of the Third Phase Campaign, the North Koreans deployed the KPA II, III and V Corps—an estimated total of 61,500 soldiers—against the UN forces on the central front.[19][34] The North Korean plan was a frontal attack at Wonju by Major General Pang Ho San's KPA V Corps, while Major General Ch'oe Hyon's KPA II Corps would infiltrate the US X Corps rear as guerrillas and block Route 29.[11][18] The goal of the offensive was to push the US X Corps back in coordination with the Chinese attacks on Seoul, thereby isolating the South Koreans forces in the Taebaek Mountains area.[19][35] As part of the Chinese attacks against Seoul, the Chinese 42nd and 66th Corps were deployed near Chuncheon in support of the KPA V Corps during the opening of the battle.[13] The KPA III Corps would act as casualty replacement pool for the KPA II and V Corps during the course of the battle.[11] But like the South Koreans they were facing, the North Korean forces were also badly depleted and understrength.[11] Although the North Koreans fielded more than 10 infantry divisions for the battle,[35] most of the divisions' strength were equivalent to a infantry regiment.[11] The start date of the Third Phase Campaign was set to the New Year's Eve in order to take advantage of the night assault under a full moon and the low alertness of the UN soldiers during the holiday.[13]
First Battle of Wonju
[edit]Opening moves
[edit]On the central front, the ROK III Corps defended the 38th parallel at the north of Gapyeong (Kapyong) and Chuncheon.[36] Composed of the ROK 2nd, 5th, 7th and 8th Infantry Divisions, the ROK III Corps placed the ROK 2nd Infantry Division on the corps' left flank at the hills north of Gapyeong, while the ROK 5th Infantry Division defended the corps' center at Chuncheon.[36] The cold winter created great difficulties for the South Korean defenders, with the heavy snow hindering construction and icy roads limiting food and ammunition supplies.[36] North Korean guerrillas were also active in the region, and had caused serious disruption in the rear of the ROK III Corps.[36]
As part of the Chinese plan to capture Seoul, the PVA 42nd and the 66th Corps was tasked with protecting the Chinese left flank by eliminating the ROK 2nd and 5th Infantry Divisions,[37] while cutting the road between Chuncheon and Seoul.[13] Following instructions, the two Chinese corps quickly struck after midnight on New Year's Eve.[38] The PVA 124th Division first penetrated the flanks of the ROK 2nd Infantry Division, then blocked the division's retreat route.[38][39] The trapped ROK 17th and 32nd Regiments of the ROK 2nd Infantry Division were forced to retreat in disarray.[38] With the PVA 66th Corps pressuring the ROK 5th Infantry Division's front, the PVA 124th Division then advanced eastward in the Korean rear and blocked the ROK 5th Infantry Division's retreat route as well.[39] The maneuver soon left the ROK 36th Regiment of the ROK 5th Infantry Division surrounded by Chinese, and the ROK 36th Regiment had to escape by infiltrating the Chinese lines using mountain trails.[40] By January 1, the ROK III Corps was in full retreat, while the corps' headquarters had lost contacts with the 2nd and 5th Infantry Divisions.[41] Responding to the crisis on the central front, the ROK III Corps sector's defense was handed over the US X Corps.[41]
While the Chinese were making concentrated attack against the South Korean front, the North Korean forces that infiltrated the UN rear were cutting the South Korean retreat route.[42] In the days before the Chinese Third Phase Campaign, the KPA II Corps established a major roadblock at the north of Hoengsong with an estimated strength of 10,000 soldiers, and it was blocking the retreat route of the ROK III Corps.[36][43] In response, the ROK II Corps and the US 2nd Infantry Division conducted a siege operation against the roadblock from both the north and the south, and the roadblock was forced open by January 2.[44][45] Although the UN forces managed to eliminate a North Korean division at the roadblock, the ROK II Corps was nearly destroyed during the fighting, and it was forced to disband on January 10.[46]
The success of the initial Chinese and North Korean attacks made the ROK I Corps to abandon its attempts to restore its original defensive position at Hyon-ri,[44] and a large number of North Korean forces soon streamed into the gap between the US 2nd Infantry Division at Wonju and the ROK I Corps on the east coast.[41] General Ridgway interpreted the Sino-Korean attack on the central front as an attempt to surround the UN defenders at Seoul, and he immediately ordered the evacuation of Seoul on January 3.[47][48] On January 5 Ridgway ordered all UN forces to withdraw to the 37th parallel to set up a new defensive line, dubbed "Line D", with the UN forces on central and eastern front setting up defenses between Wonju and the coastal city of Jumunjin (Chumunjin).[47][49] At the same time, the Chinese troops halted their offensive operations with the KPA II and V Corps relieving the PVA 42nd and 66th Corps,[15][50] and Kim Il-sung was convinced that a great victory could soon be achieved at Wonju.[35]
Wonju falls
[edit]In the aftermath of the South Korean collapse, the KPA V Corps proceeded to launch frontal attacks against Wonju while the KPA II Corps infiltrated the UN rear through the area at the east of Wonju.[51] The US 2nd Infantry Division's position at Wonju had now became an exposed northern salient,[52] and its defenses were further hampered by the flat terrain surrounding Wonju.[53] But given the strategic importance of Wonju in controlling central Korea,[11] Ridgway declared that Wonju was "only second to Seoul" in importance, therefore must be defended at all cost.[52] In accordance with Ridgway's instructions, Major General Edward Almond of the US X Corps ordered the US 2nd Infantry Division to defend the hills north of Wonju, but Major General Robert B. McClure of the US 2nd Infantry Division believed that the Wonju salient was untenable due to the flat terrain and the low morale of his division.[54] On January 7, two infantry battalions from the KPA V Corps launched an attack against the US 2nd Infantry Division.[55] One North Korean battalion managed to infiltrate the American positions disguising as refugees while another battalion launched a frontal attack,[55][56] but the weak attack was soon repulsed due to the lack of coordination between the North Korean units, and about 114 infiltrators were later captured.[57][58] Although the North Korean attack inflicted little damage unto the Americans, the disruptions caused by infiltrators in US 2nd Infantry Division's rear convinced General McClure to abandon Wonju on January 7.[55] General Almond concurred with McClure's decision on the condition that the US 2nd Infantry Division would only retreat 3 mi (4.8 km) so that Wonju could be controlled with UN artillery fire,[59] but General McClure ordered the division to retreat more than 8 mi (13 km) south and put Wonju out of artillery range.[60] With Wonju fallen under North Korean control, the Chinese declared that the Third Phase Campaign had reached a successful conclusion.[61]
Second Battle of Wonju
[edit]Hill 247
[edit]Hill 247 is located among the hill mass at 3 mi (4.8 km) south of Wonju,[60] and it is a critical height that commands the streets of Wonju from the south.[62] With the loss of Wonju on January 7, General Almond was furious at McClure for disobeying the order to hold Wonju, and this later resulted in Major General Clark Ruffner replacing McClure on January 13.[63][64] On January 8, General Almond immediately ordered the US 2nd Infantry Division to retake Wonju.[60] Following his orders, the US 23rd Infantry Regiment, under the command of Colonel Paul L. Freeman, attacked towards Wonju on January 8.[65] The 23rd Infantry Regiment managed to reach within 3,000 yd (2,700 m) at the south of Wonju and caught a sleeping North Korea regiment at Hill 247 by surprise.[65] About 200 North Korean soldiers were killed in the ensuing battle, but the alerted North Korean forces soon counterattacked by outflanking the 23rd Infantry Regiment to the east, and the 23rd Infantry Regiment was forced to retreat in order to avoid encirclement.[65]
Encouraged by the heavy North Korea losses from the initial UN attacks, General Almond again ordered the US 2nd Infantry Division to recapture Wonju on January 9.[66] About four infantry battalions from the 23rd and 38th Infantry Regiment advanced toward Wonju on January 9, but the attack was stalled at Hill 247 due to the cold weather and the lack of air support.[62][67] As the UN forces tried to dislodge the North Koreans on the next day, they were met with six defending North Korean battalions with an estimated strength of 7,000 soldiers.[67] Under heavy snowstorm and with no air support,[66] the battle for Hill 247 continued for the much of January 10, and the fighting around the French Battalion of the 23rd Infantry Regiment became particularly fierce.[67] At one point, the French Battalion was forced to fend off several North Korean counterattacks with bayonet charges after running out of ammunition.[68] The French Battalion's action at Wonju impressed General Ridgway, who later encouraged all American units in Korea to utilize bayonets in battle.[68] The North Koreans tried to encircle the attacking UN forces as the UN forces began to gain the upper hand, but artillery fire broke the North Korean formations before the action could be carried out, and the North Koreans had suffered an estimated 2,000 casualties in the aftermath of the battle.[68] When air support returned on January 11,[69] the attacking UN forces inflicted another 1,100 North Korean casualties and captured Hill 247 by January 12.[22] Although the cold weather and the stubborn North Korean defenses prevented the UN forces from entering Wonju, the capture of Hill 247 had put the entire Wonju within UN artillery range, and the village soon became a no man's land under the devastating UN bombardment.[70]
Anti-guerrilla operations
[edit]Although the capture of Hill 247 had forced the KPA V Corps to abandon Wonju with heavy losses on January 17,[71][72] the KPA II Corps' infiltration in the UN rear area had became so serious such that it threatened to outflank the entire UN front and force a complete UN evacuation of Korea by mid January.[73][74] With the bulk of the US X Corps tied up at the south of Wonju while the entire ROK III Corps in disarray, the front between Wonju and Korean east coast was undefended, and about 16,000 North Korean soldiers entered the gap while establishing guerrilla bases from Tanyang to Andong.[75] The battles along the central front soon degenerated into irregular warfare between company sized UN patrols and North Korean guerrilla bands.[76] In an effort to stabilize the front, Ridgway ordered the US 2nd Infantry Division to withdraw from Wonju while pushing the central front back by 40 mi (64 km) and into the area between Wonju and Samch'ok.[61][77] He also sent the US 187th Regimental Combat Team, the US 5th Cavalry Regiment and the US 1st Marine Division to contain North Korean guerrillas at the east of Route 29 and at the north of Andong and Yongdok.[78][79] About 30,000 American infantry were soon deployed to the central front by mid January,[80] and the North Korean guerrillas were blocked in a narrow salient along the hills at the east of Route 29.[81]
To eliminate the North Korean threat in the UN rear, General Almond ordered the all X Corps units at Route 29 to launch aggressive patrols in order to destroy the North Korean supply bases and guerrilla bands.[82] Specially trained irregular forces, such as X Corps' Special Action Group, also hunted North Korean units by operating as guerrilla units themselves.[81] The constant UN pressure slowly drained the ammunition and the manpower supply of the KPA II Corps,[82] while Major General Yu Jai Hung rallied the ROK III Corps and closed the gap between Wonju and the Korean east coast by January 22.[83] On January 20, a patrol carried out by the the US 9th Infantry Regiment of the US 2nd Infantry Division managed to reoccupy Wonju without much resistance.[84] Lacking reinforcements and resupplies, the KPA II Corps was completely scattered by the end of January, and only 8,600 soldiers from the KPA II Corps managed to survive and retreat back to North Korea.[85] The KPA 10th Division, vanguard of the KPA II Corps, was also annihilated during the UN anti-guerrilla operations.[86]
Aftermath
[edit]By the end of January, the KPA II Corps was completely decimated during its guerrilla operations, and its estimated strength was reduced from 16,000 to 8,000.[3] The KPA V Corps' attempt to capture Wonju had also resulted in crippling casualties, and its estimated strength was reduced from 32,000 to 22,000 by the end of January.[3] In contrast, the UN losses were relatively moderate during the same period.[87] The defeat of the North Korean army enabled the UN forces to consolidate their positions along the Korean central and eastern front,[86] and the retreating US Eighth Army on the Korean western front could finally return to the offensive after its rear and eastern flank were secured.[88] As soon as the US X Corps regained full control of the Korean central front at the end of January, General Ridgway immediately ordered the US Eighth Army to launch Operation Thunderbolt against Chinese and North Korean forces on January 25, 1951.[88][89]
