Battle of Chosin Reservoir
The Battle of Chosin Reservoir, also known as the Chosin Reservoir Campaign or the Battle of Jhangjin Lake (Korean: 장진호 전투; hanja: 長津湖戰鬪; rr: Jangjin ho jeontu; Chinese: 长津湖战役; pinyin: Chángjīn Hú Zhànyì). The name "Chosin" is derived from the Japanese pronunciation "Chōshin", instead of Korean pronunciation "Changjin", of the Chinese word 長津.
Official Chinese sources refer to this battle as the eastern part of the Second Phase Offensive (or Campaign) (第二次战役东线). The Western half of the Second Phase Offensive resulted in the Battle of the Ch'ongch'on River.
The battle was decisive in the Korean War. The battle took place about a month after the People's Republic of China entered the conflict and sent the People's Volunteer Army (PVA) 9th Army to infiltrate the northeastern part of North Korea. On 27 November 1950, the Chinese force surprised the US X Corps commanded by Major General Edward Almond at the Chosin Reservoir area. A brutal 17-day battle in freezing weather soon followed. Between 27 November and 13 December, 30,000:24 United Nations troops (later nicknamed "The Chosin Few") under the field command of Major General Oliver P. Smith were encircled and attacked by about 120,000 Chinese troops under the command of Song Shilun, who had been ordered by Mao Zedong to destroy the UN forces. The UN forces were nevertheless able to break out of the encirclement and to make a fighting withdrawal to the port of Hungnam, inflicting heavy casualties on the Chinese. US Marine units were supported in their withdrawal by the US Army's Task Force Faith to their east, which suffered heavy casualties and the full brunt of the Chinese offensive. Following the retreat of the US Eighth Army from northwest Korea in the aftermath of the Battle of the Ch'ongch'on River, the evacuation of the X Corps from the port of Hungnam in northeast Korea marked the complete withdrawal of UN troops from North Korea.
By mid-October 1950, after the successful landing at Inchon by the US X Corps and the subsequent destruction of the Korean People's Army, the Korean War appeared to be all but over. United Nations (UN) forces advanced rapidly into North Korea with the intention of reuniting North and South Korea before the end of 1950. North Korea is divided through the center by the impassable Taebaek Mountains, which separated the UN forces into two groups.:3 The US Eighth Army advanced north through the western coast of the Korean Peninsula, while the Republic of Korea (ROK) I Corps and the US X Corps advanced north on the eastern coast.:3
At the same time the People's Republic of China entered the conflict after issuing several warnings to the United Nations.:101–7 On 19 October 1950, large formations of Chinese troops, dubbed the People's Volunteer Army (PVA), secretly crossed the border and into North Korea.:145-9 One of the first Chinese units to reach the Chosin Reservoir area was the PVA 42nd Corps, and it was tasked with stopping the eastern UN advances. On 25 October, the advancing ROK I Corps made contact with the Chinese and halted at Funchilin Pass (40°12′14″N 127°18′00″E / 40.204°N 127.3°E), south of the Chosin Reservoir.:5 After the landing at Wonsan, the US 1st Marine Division of the X Corps engaged the defending PVA 124th Division on 2 November, and the ensuing battle caused heavy casualties among the Chinese.:7 On 6 November, the PVA 42nd Corps ordered a retreat to the north with the intention of luring the UN forces into the Chosin Reservoir.:47 By 24 November, the 1st Marine Division occupied both Sinhung-ni (40°33′25″N 127°16′12″E / 40.557°N 127.27°E) on the eastern side of the reservoir, and Yudami-ni (40°28′48″N 127°06′43″E / 40.48°N 127.112°E) on the west side of the reservoir.:8
Faced with the sudden attacks by Chinese forces in the Eighth Army sector, General Douglas MacArthur ordered the Eighth Army to launch the Home-by-Christmas Offensive. To support the offensive, MacArthur ordered the X Corps to attack west from the Chosin Reservoir and to cut the vital Manpojin—Kanggye—Huichon supply line.:11 As a response, Major General Edward M. Almond, commander of the US X Corps, formulated a plan on 21 November. It called for the US 1st Marine Division to advance west through Yudami-ni, while the US 7th Infantry Division would provide a regimental combat team to protect the right flank at Sinhung-ni. The US 3rd Infantry Division would also protect the left flank while providing security in the rear area.:14 By then the X Corps was stretched thin along a 400-mile front.:8
Surprised by the Marine landing at Wonsan, China's Chairman Mao Zedong called for the immediate destruction of the ROK Capital Division, ROK 3rd Infantry Division, US 1st Marine Division, and US 7th Infantry Division in a telegraph to Commander Song Shilun of the PVA 9th Army on 31 October.:47-8 Under Mao's urgent orders, the 9th Army was rushed into North Korea on 10 November.:21 Undetected by UN intelligence,:35 the 9th Army quietly entered the Chosin Reservoir area on 17 November, with the 20th Corps of the 9th Army relieving the 42nd Corps near Yudami-ni.:47
Location, terrain and weather
Chosin Reservoir is a man-made lake located in the northeast of the Korean peninsula. The name Chosin is the Japanese pronunciation of the Korean place name Changjin, and the name stuck due to the outdated Japanese maps used by UN forces. The battle's main focus was around the 78-mile (126 km) long road that connects Hungnam and Chosin Reservoir,:32 which served as the only retreat route for the UN forces.:29 Through these roads, Yudami-ni and Sinhung-ni, located at the west and east side of the reservoir respectively, are connected at Hagaru-ri (now Changjin-ŭp) (40°23′02″N 127°14′56″E / 40.3838°N 127.249°E). From there, the road passes through Koto-ri (40°17′02″N 127°18′00″E / 40.284°N 127.3°E) and eventually leads to the port of Hungnam.:28–31 The area around the Chosin Reservoir was sparsely populated.:25
The battle was fought over some of the roughest terrain during some of the harshest winter weather conditions of the Korean War.:24 The road was created by cutting through the hilly terrain of Korea, with steep climbs and drops. Dominant peaks, such as the Funchilin Pass and the Toktong Pass (40°23′38″N 127°09′40″E / 40.3938°N 127.161°E), overlook the entire length of the road. The road's quality was poor, and in some places it was reduced to a one lane gravel trail.:28–31 On 14 November 1950, a cold front from Siberia descended over the Chosin Reservoir, and the temperature plunged to as low as −35 °F (−37 °C).:xi The cold weather was accompanied by frozen ground, creating considerable danger of frostbite casualties, icy roads, and weapon malfunctions. Medical supplies froze; morphine syrettes had to be defrosted in a medic's mouth before they could be injected; frozen blood plasma was useless on the battlefield. Even cutting off clothing to deal with a wound risked gangrene and frostbite. Batteries used for the Jeeps and radios did not function properly in the temperature and quickly ran down. The lubrication in the guns gelled and rendered them useless in battle. Likewise, the springs on the firing pins would not strike hard enough to fire the round, or would jam.
Forces and strategies
Although the 1st Marine Division landed at Wonsan as part of Almond's US X Corps, Almond and Major General Oliver P. Smith of the 1st Marine Division shared a mutual loathing of each other that dated back to a meeting before the landing at Inchon, when Almond had spoken of how easy amphibious landings are even though he had never been involved in one. Smith believed there were large numbers of Chinese forces in North Korea despite the fact that higher headquarters in Tokyo said otherwise,:428 but Almond felt Smith was overly cautious.:434 The mutual distrust between the commanders caused Smith to slow the 1st Marine Division's advance towards the Chosin Reservoir in violation of Almond's instructions.:429 Smith established supply points and airfields along the way at Hagaru-ri and Koto-ri.:433–4
As the US X Corps was pushing towards the reservoir, the Chinese formulated their strategy, based on their experiences in the Chinese Civil War.:52 Working from the assumption that only a light UN presence would be at the reservoir, the Chinese 9th Corps Army was first to destroy the UN garrisons at Yudami-ni and Sinhung-ni, then push towards Hagaru-ri.:52 Believing the bulk of the US X Corps would move to rescue the destroyed units, the 9th Army would then block and trap the main UN forces on the road between Hagaru-ri and Hungnam.:52 The 9th Army initially committed eight divisions for the battle,:436 with most of the forces concentrated at Yudami-ni and Sinhung-ni.:52
The flaw in the Chinese plan was a lack of accurate intelligence about the UN forces.:296 Even though the US X Corps was stretched thin over northeast Korea, the slow Marine advance allowed the bulk of the US 1st Marine Division, including the 5th, 7th and 11th Marines, to be concentrated at Yudami-ni.:435:42 Furthermore, the strategically important Hagaru-ri, where a C-47-capable airfield was under construction and a supply dump,:158-62 was not a priority for the Chinese despite being lightly defended by the 1st and 7th Marines.:158–9 Only Regimental Combat Team 31 (RCT-31), an understrength and hastily formed regimental combat team of the US 7th Infantry Division, was thinly spread along the eastern bank of the reservoir.:75 Those units would later take the brunt of the Chinese assaults. As for the UN forces, the 1st Marine Division had an effective strength of 25,473 men at the start of the battle,:24, 37 and it was further reinforced by the British 41 Royal Marine Commando and the equivalent of two regiments from the 3rd and 7th Army Infantry Divisions.:24 The UN forces had a combined strength of about 30,000 men during the course of the battle.:24 The UN forces at Chosin were also supported by one of the greatest concentrations of air power during the Korean War,:250 since the 1st Marine Aircraft Wing stationed at Yonpo Airfield and five aircraft carriers from the US Navy's Task Force 77 were able to launch 230 sorties daily to provide close air support during the battle,:250 while the US Air Force Far East Combat Cargo Command in Japan reached the capacity of airdropping 250 tons of supplies per day to resupply the trapped UN forces.:182
Although the 9th Corps Army was one of China's elite formations, composed of veterans and former POWs from the Huaihai Campaign,:52 several deficiencies hampered its ability during the battle. Initially the 9th Army was intended to be outfitted in Manchuria during November, but Mao suddenly ordered it into Korea before that could happen. As a result, the 9th Corps Army had almost no winter clothing for the harsh Korean winter. Similarly, poor logistics forced the 9th Corps Army to abandon heavy artillery,:36 while working with little food and ammunition. The food shortage forced the 9th Corps Army to initially station a third of its strength away from the Chosin Reservoir in reserve, and starvation and exposure broke out among the Chinese units, since foraging was not an option in the sparsely populated area. By the end of the battle, more Chinese troops had died from the cold than from combat and air raids.
The Chinese strength is usually estimated at 120,000 troops for the battle, since the 9th Army was composed of 12 divisions with a strength of 10,000+ men per division.:17–8 Before arriving in Korea, the 9th Corps Army was also reinforced. Each of its three corps now had four divisions instead of the regular three. Infantry from two formerly liberated (surrendered) Nationalist divisions were absorbed to bring each infantry company up to strength. Some companies had approximately 150 men, but other companies were reinforced with more than 200 men. On average, each division of the 9th Army had more infantry troops than other Chinese divisions.
Eventually, all 12 Chinese divisions of the 9th Corps Army were deployed. Eight divisions of the PVA 20th and 27th Corps served as the main attacking force. Four divisions of the PVA 26th Corps initially were held back in reserve, and deployed after 20th and 27th Corps exhausted all their available strength.
On the night of 27 November, the PVA 20th and 27th Corps of the 9th Corps Army launched multiple attacks and ambushes along the road between the Chosin Reservoir and Kot'o-ri. At Yudam-ni, the 5th, 7th and 11th Marines were surrounded and attacked by the PVA 79th and 89th Divisions, with the 59th Division attacking the road between Yudam-ni and Hagaru-ri to cut off communication. Similarly, RCT-31 was isolated and ambushed at Sinhung-ni by the PVA 80th, 81st and 94th Divisions. At Hagaru-ri, the 1st Marine Division command headquarters was attacked by the PVA 58th Division. Finally, the PVA 60th Division surrounded elements of the 1st Marines at Kot'o-ri from the north.:52 Caught by complete surprise, the UN forces were cut off at Yudam-ni, Sinhung-ni, Hagaru-ri and Kot'o-ri by 28 November.:72
Actions at Yudam-ni
Acting on Almond's instruction, Smith ordered the 5th Marines to attack west toward Mupyong-ni on 27 November.:52 The attack was soon stalled by the PVA 89th Division and forced the Marines to dig in on the ridges surrounding Yudam-ni.:301:56 As night came, three Chinese regiments of the 79th Division attacked the ridges on the north and northwest of Yudam-ni, hoping to annihilate the garrison in one stroke.:68 Close range fighting soon developed as the attackers infiltrated Marine positions,:64-8 but the 5th and 7th Marines held the line while inflicting heavy casualties on the Chinese.:68-71:74 As day broke on 28 November, the Chinese and Americans were locked in a stalemate around the Yudam-ni perimeter.:71
While the battle was underway at Yudam-ni, the PVA 59th Division blocked the road between Yudam-ni and Hagaru-ri by attacking the defending Charlie and Fox Companies of the 7th Marines.:227 The successful assault forced Charlie Company to retreat into Yudam-ni, which left Fox Company commanded by Captain William E. Barber isolated on a hill overlooking the Toktong Pass, a vital pass that controlled the road.:73 On 29 November, several efforts by the 7th Marines failed to rescue Fox Company, despite inflicting heavy casualties on the Chinese.:178 Aided by artillery from Hagaru-ri and Marine Corsair fighters, Fox Company managed to hold out for five days while enduring constant attacks by the PVA 59th Division.:226
After the heavy losses suffered by the PVA 79th Division at Yudam-ni, 9th Corps Army headquarters realized that the bulk of the 1st Marine Division was stationed at Yudam-ni, with a garrison strength that was double the initial estimate.:329 Believing that any further assaults would be futile, Song Shilun ordered the 9th Army to switch their main attacks toward Sinhung-ni and Hagaru-ri,:329 leaving Yudam-ni alone from 28 to 30 November.:213 At the same time, the US Eighth Army on the Korean western front was forced into full retreat at the Battle of the Ch'ongch'on River, and MacArthur ordered Almond to withdraw the US X Corps to the port of Hungnam.:120–1 Acting on the instruction of Almond and Smith, Lieutenant Colonel Raymond L. Murray and Colonel Homer L. Litzenberg, commanders of the 5th and 7th Marines, respectively, issued a joint order to break out from Yudam-ni to Hagaru-ri on 30 November.:215 Faced with tough fighting between the blocking Chinese divisions and the withdrawing Marines, Smith remarked: "Retreat, hell! We're not retreating, we're just advancing in a different direction."
For the breakout, the Marines formed into a convoy with a single M4A3 Sherman tank as the lead. The plan was to have 3rd Battalion, 5th Marines (3/5) as the vanguard of the convoy, with three battalions covering the rear. At the same time, 1st Battalion, 7th Marines (1/7) would attack towards Fox Company in order to open the road at Toktong Pass.:215–6 To start the breakout, 3rd Battalion, 7th Marines (3/7) had to first attack south and capture Hills 1542 and 1419 in order to cover the road from Chinese attacks.:218 The breakout was carried out under the air cover of the 1st Marine Air Wing.:214
On the morning of 1 December, 3/7 Marines engaged the PVA 175th Regiment of the 59th Division at Hills 1542 (40°26′06″N 127°06′25″E / 40.435°N 127.107°E) and 1419 (40°25′41″N 127°08′06″E / 40.428°N 127.135°E). The Chinese defenders soon forced the Marines to dig in on the slopes between the road and the peaks:220 when the convoy passed 3/7's position by the afternoon.:218 With Hagaru-ri still not captured, the PVA High Command scrambled the 79th Division to resume attacks on Yudam-ni, while the 89th Division rushed south towards Kot'o-ri.:88 The Chinese struck at night, and the ferocity of the fighting forced the rear covering forces to call in night fighters to suppress the attacks.:223 The fighting lasted well into the morning of 2 December until all the Marines had managed to withdraw from Yudam-ni.:223
At the same time, 1/7 Marines also tried to break the Chinese blockade at Hill 1419 on 1 December. Despite being badly reduced by combat, hunger and frostbite, the PVA 59th Division sent in its last five platoons and refused to yield.:86 As night approached, 1/7 finally captured the peak and started to march through the hills on the east side of the road.:233 Relying on the element of surprise, they managed to destroy several Chinese positions along the road.:234 On the morning of 2 December, a joint attack by Fox Company and 1/7 secured the Toktong Pass, thus opening the road between Yudam-ni and Hagaru-ri.:235
Although the road had been opened between Yudam-ni and Hagaru-ri, the convoy still had to fight through the numerous Chinese positions on the hills overlooking the road. On the first night of the retreat, the Chinese struck the convoy in force and inflicted heavy casualties on 3/5 Marines.:221–3 Although strong air cover suppressed most of the Chinese forces for the rest of the march, the cold weather, harassing fire, raiding parties, and roadblocks slowed the retreat to a crawl, while inflicting numerous casualties.:224–5 Despite those difficulties, the convoy reached Hagaru-ri in an orderly fashion on the afternoon of 3 December, with the withdrawal completed on 4 December.:239-43
East of the reservoir
RCT-31, later known as "Task Force Faith," was a hastily formed regimental combat team from the 7th Infantry Division that guarded the right flank of the Marine advance towards Mupyong-ni. Before the battle, RCT-31 was spread thin, with main elements separated on the hills north of Sinhung-ni, the Pyungnyuri Inlet west of Sinhung-ni, and the town of Hudong-ni (40°26′N 127°17′E / 40.43°N 127.28°E) south of Sinhung-ni.:85 Although the Chinese believed RCT-31 to be a reinforced regiment,:329 the task force was actually understrength, with one battalion missing, due to the bulk of the 7th Infantry Division being scattered over northeast Korea.:85
On the night of 27 November, three regiments from the 80th Division attacked the northern hills (40°29′20″N 127°15′32″E / 40.489°N 127.259°E) and the inlet,:53-4 completely surprising the defenders.:89 The ensuing battle inflicted heavy casualties on the 1st Battalion, 32nd Infantry, to the north of Sinhung-ni,:93 while the 57th Field Artillery Battalion and the 3rd Battalion, 31st Infantry, were almost overrun at the Pyungnyuri Inlet.:97 The Chinese also sent the 242nd Regiment of the 81st Division towards Hill 1221 (40°26′56″N 127°16′05″E / 40.449°N 127.268°E),:55 an undefended hill that controlled the road between Sinhung-ni and Hudong-ni.:98 As the night's fighting ended, RCT-31 was separated into three elements.:310
Believing that the defenders had been completely destroyed at the inlet, the Chinese stopped their attacks and proceeded to loot the US positions for food and clothing.:58 As morning came on 28 November, the 3/31st Infantry counterattacked the PVA 239th Regiment at the inlet, sending the surprised Chinese back in a complete rout.:58:96 In the afternoon, Almond flew into the Sinhung-ni perimeter of RCT-31, convinced that RCT-31 was strong enough to begin its attack north and deal with whatever "remnants" of Chinese forces that were in their way. Almond ordered Colonel Allan D. Maclean, the commander of RCT-31, to resume the offensive north while presenting Silver Stars to three of Maclean's officers. In disgust, Lieutenant Colonel Don C. Faith, Jr., the commander of the 1/32nd Infantry, threw his medal into the snow.:102–3
On the night of 28 November, the PVA 80th Division attacked again with four regiments.:59 At the inlet, the Chinese assault became a disaster as communications broke down, while devastating fire from the M16 and M19 anti-aircraft (AA) guns attached to the 57th Field Artillery Battalion swept the Chinese ranks.:59-60:107 In the aftermath of the fighting, the PVA 238th and the 239th Regiment together had fewer than 600 soldiers.:61 The attacks by PVA 240th Regiment, on the other hand, forced Maclean to order a retreat from the northern hills towards Sinhung-ni.:110 On 29 November, the 1st Battalion managed to break through the Chinese blockade and reached the Sinhung-ni perimeter, but Maclean was lost when he mistook some Chinese soldiers for American.:114 The Chinese finally stopped their attacks on the night of 29 November, while waiting for fresh reinforcements.:62
While RCT-31 was under siege, Almond finally instructed the 1st Marine Division to rescue RCT-31 by breaking out of Yudam-ni, an impossible order for Smith to implement.:183 Only the 31st Tank Company tried to rescue RCT-31 by attacking Hill 1221 from Hudong-ni,:103 but without infantry support, the two armored attacks on 28 and 29 November were stalled by slippery roads, rough terrain, and close infantry assaults.:103–5, 118–9 By 30 November, the US forces evacuated Hudong-ni in order to defend Hagaru-ri, leaving the rest of RCT-31 completely stranded.:126
On 30 November, Major General David G. Barr, the commander of the 7th Infantry Division, flew into Sinhung-ni and met with Faith, who by now had assumed command of RCT-31. Faith expressed the difficulties for a breakout, particularly the 500 wounded that RCT-31 had to bring along.:124 On the same day, parts of the PVA 94th Division and the rest of the 81st Divisionarrived as reinforcements for the 80th Division.:62 By midnight, six Chinese regiments renewed their attacks, and Zhan Danan, the commander of the 80th Division, ordered the complete destruction of RCT-31 before dawn.:63 Again, the 57th Battalion's AA guns held the Chinese at bay,:129–30 but the shell supplies were running desperately low.:134 On the day of 1 December, Faith finally ordered RCT-31 to breakout from Sinhung-ni and withdraw to Hagaru-ri.:134
The breakout began as soon as the weather allowed the 1st Marine Aircraft Wing to provide air cover on 1 December.:132-5 As the soldiers formed a convoy and tried to leave the Sudong-ni perimeter, the PVA 241st Regiment immediately swarmed over the American forces,:137 with three other regiments closing in.:64 Left with no choice, the covering aircraft dropped napalm right in front of RCT-31, causing casualties among both Chinese and US troops.:137–138 The resulting firestorm wiped out the blocking Chinese company,:64 allowing the convoy to advance.:138 As the front of RCT-31 made their way forward, heavy small arms fire caused many members of the rear guard to seek shelter below the road instead of protecting the trucks.:138 Chinese fire also killed or wounded those already in the trucks as well as the drivers, who viewed the job as a form of suicide.:139 Slowly, the convoy approached a roadblock under Hill 1221 in the late afternoon.:140 Several parties tried to clear Hill 1221, but after taking part of the hill, the leaderless soldiers continued out onto the frozen reservoir instead of returning to the column.:144 As Faith led an assault on the roadblock, he was hit by a Chinese grenade and subsequently died of his wounds.:146 The convoy managed to fight past the first roadblock, but as it reached the second at Hudong-ni, RCT-31 disintegrated under Chinese attacks.:150 Out of the original 2,500 soldiers, about 1,050 managed to reach Hagaru-ri, and only 385 survivors were deemed able-bodied.:339 The remnants of RCT-31 were formed into a provisional army battalion for the rest of the battle.:249
Actions at Hagaru-ri
To support the Marine attack towards Mupyong-ni, Hagaru-ri became an important supply dump with an airfield under construction. Smith and 1st Marine Division headquarters were also located at Hagaru-ri.:72 With the bulk of the 1st Marine Division gathered at Yudam-ni, Hagaru-ri was lightly defended by two battalions from the 1st and 7th Marines, the rest of the garrison being composed of engineers and rear support units from both the Army and the Marine Corps.:322
The original Chinese plan called for the 58th Division to attack Hagaru-ri on the night of 27 November, but the division became lost in the countryside due to the outdated Japanese maps it used.:74 It was not until the dawn of 28 November that the 58th Division arrived at Hagaru-ri.:74 Meanwhile, from the fighting and ambushes that had occurred the previous night, the garrison at Hagaru-ri noticed the Chinese forces around them. Lieutenant Colonel Thomas L. Ridge, commander of 3rd Battalion, 1st Marines (3/1), predicted the Chinese attack would come on the night of 28 November.:162 Almost everyone, including rear support units with little combat training, was pressed into service on the front line due to the manpower shortage,:174 and the entire perimeter was on full alert by 21:30.:163
It was not long before the PVA 173rd Regiment attacked the western and the southern perimeter, while the 172nd Regiment struck the hills on the northern perimeter.:317 Despite the preparations, the understrength garrison was overwhelmed, with the Chinese opening several gaps in the defenses and reaching the rear areas.:165 The resulting chaos, however, caused a breakdown in discipline among the Chinese soldiers, who began looting food and clothing instead of exploiting the situation.:324 The defending Americans managed to destroy the Chinese forces in counterattacks, while a breakdown of communications between the Chinese regiments allowed the gaps to close.:174 When the fighting stopped, the Chinese had only gained the East Hill (40°23′13″N 127°15′32″E / 40.387°N 127.259°E) on the northern perimeter.:174 Another attack was planned for the night of 29 November, but air raids by VMF-542 broke up the Chinese formations before it could be carried out.:195
Given the critical manpower shortage at Hagaru-ri, on November 29, Smith ordered Colonel Lewis "Chesty" Puller of the First Marine Regiment to assemble a task force to be sent north from Kot'o-ri to open the road south of Hagaru-ri.:186 A task force was formed with 921 troops from the 41 Royal Marine Commando, G Company of the 1st Marines and B Company of the 31st Infantry.:187 It was dubbed "Task Force Drysdale" after its commander, Lieutenant Colonel Douglas B. Drysdale, who also commanded 41 Commando.:187 On the afternoon of 29 November, Task Force Drysdale pushed north from Koto-ri, while under constant attack from the PVA 60th Division.:78:189 The task force's harrowing experience later earned the road the nickname "Hell Fire Valley".:193 As the Chinese attacks dragged on, the task force became disorganized,:191 and a destroyed truck in the convoy later split the task force into two segments.:192 Although the lead segment fought its way into Hagaru-ri on the night of 29 November, the rear segment was destroyed.:327 Despite suffering 162 dead and missing and 159 wounded, the task force managed to bring in 300 badly needed infantrymen for the defense at Hagaru-ri.:201
As more reinforcements arrived from Hudong-ni on 30 November,:204 the garrisons attempted to recapture the East Hill. All efforts failed, despite the destruction of a Chinese company.:80:203 When darkness settled, the PVA 58th Division gathered its remaining 1,500 soldiers in a last-ditch attempt to capture Hagaru-ri.:81 The reinforced defenders annihilated most of the attacking forces, with only the defences around the East Hill giving way.:205 As the Chinese tried to advance from the East Hill, they were cut down by the 31st Tank Company.:206
By 1 December, the PVA 58th Division was virtually destroyed,:340 with the remainder waiting for reinforcements from the 26th Corps of the 9th Army.:97:251 Much to the frustration of Song Shilun, the 26th Corps did not arrive before the Marines broke out of Yudam-ni. The airfield was opened to traffic on 1 December, allowing UN forces to bring in reinforcements and to evacuate the dead and wounded.:208 With the Marines at Yudam-ni completing their withdrawal on 4 December, the trapped UN forces could finally start their breakout towards the port of Hungnam.
After a short rest, the breakout began on 6 December, with the 7th Marines as the vanguard of the retreating column, while the 5th Marines covered the rear.:247 At the same time, the much-delayed PVA 26th Corps arrived at Hagaru-ri with its 76th and 77th Divisions to relieve the 58th and 60th Divisions.:379 As the 7th Marines pushed aside the PVA 76th Division south of Hagaru-ri, the 5th Marines took over the Hagaru-ri perimeter and recaptured the East Hill from the 76th Division.:382:260 In a last effort to stop the breakout,:382 the customary Chinese night attack was launched, with the 76th and 77th Division striking the Hagaru-ri perimeter from all directions.:97 The Marines repulsed the attacks, inflicting heavy casualties.:262
Meanwhile, the 7th Marines opened the road between Hagaru-ri and Koto-ri by capturing the high ground surrounding the road. But as soon as the Marines pulled out, the 77th Division returned to the peaks and attacked the column.:382–3:257 Chaotic fighting broke out and the retreat was slowed to a crawl.:257–9 The Marine night fighters, however, returned to subdue the Chinese forces,:257 and most of the blocking troops were eliminated.:383 On 7 December, the rest of the column managed to reach Kot'o-ri with little difficulty, with the last elements reaching Kot'o-ri that night.:361
After the failure of the 26th Corps at Hagaru-ri, the PVA High Command ordered the 26th and 27th Corps to chase the escaping UN force, with the 20th Corps assigned to block the escape route.:383:103 But with most of the 20th Corps destroyed at Yudam-ni and Hagaru-ri, the only forces between Kot'o-ri and Hungnam were the remnants of the 58th and 60th Divisions.:341 In desperation, Song Shilun ordered these troops to dig in at Funchilin Pass, while blowing up the vital treadway bridge, hoping the terrain and obstacles would allow the 26th and 27th Corps to catch up with the retreating UN forces.:341 The PVA 180th Regiment that occupied Hill 1081 (40°13′59″N 127°19′34″E / 40.233°N 127.326°E) blew up the original concrete bridge and two improvised replacements in succession, believing the bridge was rendered irreparable.:137:288-96 In response, the 1st Battalion, 1st Marines (1/1) attacked Hill 1081 from the south, and the hill was captured on 9 December, though the defenders fought to the last man.:300–1 At the same time, the 7th Marines and RCT-31 attacked the treadway bridge from the north, only to encounter defenders who were already frozen in their foxholes.:364
With the path to Hungnam blocked at Funchilin Pass, eight C-119 Flying Boxcars flown by the US 314th Troop Carrier Wing were used to drop portable bridge sections by parachute.:297 The bridge, consisting of eight separate 18 ft (5.5 m) long, 2,900 lb (1,300 kg) sections, was dropped one section at a time, using a 48 ft (15 m) parachute on each section.:296 Four of these sections, together with additional wooden extensions were successfully reassembled into a replacement bridge by Marine Corps combat engineers and the US Army 58th Engineer Treadway Bridge Company on 9 December, enabling UN forces to proceed.:296-304 Outmaneuvered, the PVA 58th and 60th Divisions still tried to slow the UN advance with ambushes and raids, but after weeks of non-stop fighting, the two Chinese divisions combined had only 200 soldiers left.:108 The last UN forces left Funchilin Pass by 11 December.:314
One of the last engagements during the withdrawal was an ambush at Sudong (40°10′12″N 127°19′26″E / 40.17°N 127.324°E) by the pursuing PVA 89th Division,:108 which Task Force Dog of the 3rd Infantry Division repulsed with little difficulty.:307–10 The trapped UN forces finally reached the Hungnam perimeter by 21:00 on 11 December.:316
Evacuation at Hungnam
By the time the UN forces arrived at Hungnam, MacArthur had already ordered the evacuation of the US X Corps on 8 December in order to reinforce the US Eighth Army, which by then was badly depleted and retreating rapidly towards the 38th parallel.:158–9:324 Following his orders, the ROK I Corps, the ROK 1st Marine Regiment and the US 3rd and 7th Infantry Divisions had also set up defensive positions around the port.:319–320 Some skirmishes broke out between the defending US 7th, 17th and 65th Infantry and the pursuing PVA 27th Corps,:324–327 but against the strong naval gun fire support provided by US Navy Task Force 90, the badly mauled 9th Army was in no shape to approach the Hungnam perimeter.:324:393–4
In what US historians called the "greatest evacuation movement by sea in US military history",:340 a 193-ship armada assembled at the port and evacuated not only the UN troops, but also their heavy equipment and roughly a third of the Korean refugees.:367 One Victory ship, the SS Meredith Victory, evacuated 14,000 refugees by herself, despite being designed to carry only 12 passengers. The last UN unit left at 14:36 on 24 December, and the port was destroyed to deny its use to the enemy.:340 The PVA 27th Corps entered Hungnam on the morning of 25 December.:113
The US X Corps and the ROK I Corps reported a total of 10,495 battle casualties: 4,385 US Marines, 3,163 US Army personnel, 2,812 South Koreans attached to American formations and 78 British Royal Marines.:347 The 1st Marine Division also reported 7,338 non-battle casualties due to the cold weather.:345 Despite the losses, the US X Corps preserved much of its strength.:356 About 105,000 soldiers, 98,000 civilians, 17,500 vehicles, and 350,000 tons of supplies were shipped from Hungnam to Pusan,:367 and they would later rejoin the war effort in Korea. Commanding General Smith was credited for saving the US X Corps from destruction,:430 while the 1st Marine Division, the 41 Royal Marines Commando and RCT-31 were awarded the Presidential Unit Citation for their tenacity during the battle. Fourteen Marines, two other soldiers and one Navy pilot received the Medal of Honor, and all of the UN troops that served at Chosin were later honored with the nickname "The Chosin Few". On 15 September 2010, the Veterans of the Korean War Chosin Reservoir Battle memorial was unveiled by the United States Marine Corps Commandant General James T. Conway at Camp Pendleton.
The PVA 9th Army, on the other hand, officially reported 48,156 casualties during the course of the battle - about one third of its total strength. Of those casualties, 19,202 were attributed to combat, while 28,954 were attributed to the harsh Korean winter and lack of food. Outside of official channels, the estimation of Chinese casualties has been described as high as 60,000 by Patrick C. Roe, the chairman of Chosin Few Historical Committee, citing the number of replacements requested by 9th Army in the aftermath of the battle.:394 Regardless of the varying estimates, historian Yan Xue of PLA National Defence University noted that the 9th Army was put out of action for three months, describing the situation as a "giant hospital". With the absence of 9th Army, the Chinese order of battle in Korea was reduced to 18 infantry divisions by December 31, 1950, as opposed to the 30 infantry divisions present on November 16, 1950.
During the battle, UN dead were buried at temporary grave sites along the road. Operation Glory took place from July to November 1954, during which the dead of each side were exchanged. The remains of 4,167 US soldiers were exchanged for 13,528 North Korean and Chinese dead. In addition, 546 civilians who died in UN prisoner-of-war camps were turned over to the South Korean government. After Operation Glory, 416 Korean War "unknowns" were buried in the National Memorial Cemetery of the Pacific (the "Punchbowl Cemetery" in Honolulu, Hawaii). According to a Defense Prisoner of War/Missing Personnel Office (DPMO) white paper, 1,394 names were also transmitted from the Chinese and North Koreans during the operation, of which 858 proved to be correct. The 4,167 returned remains were found to be 4,219 individuals, of whom 2,944 were found to be Americans, with all but 416 identified by name. Of the 239 Korean War unaccounted for, 186 are not associated with the Punchbowl Cemetery unknowns. From 1990 to 1994, North Korea excavated and returned more than 208 sets of remains, which possibly include 200 to 400 US servicemen, but very few have been identified due to the co-mingling of remains. From 2001 to 2005, more remains were recovered from the Chosin Battle site, and around 220 were recovered near the Chinese border between 1996 and 2006.
Sources have described the outcome as a draw, characterizing it neither as an American defeat nor a Chinese victory. Roy E. Appleman, the author of US Army official history South to Naktong, North to Yalu, said that both sides could claim victory: the PVA 9th Army ultimately held the battlefield, while X Corps defeated the 9th Army in a series of battles that enabled it to withdraw most of its forces as an effective tactical unit.:355-6 Allan R. Millett has similarly said that Chosin was a geographic victory for the Chinese, as they forced the entire X Corps to evacuate to South Korea, but the campaign "nevertheless ruined the CPVF Ninth Army Group, which did not return to the front until March 1951, and it convinced the UNC that allied ground troops could defeat Chinese armies, however numerous."
The actions of the 1st Marine Division at Chosin have been of particular note, with some assessments tying them specifically to the determination of the outcome of the war. Sources have characterized them as a successful tactical withdrawal, and the division's engagement is now regarded as a defining event in the Corps' history. Roe asserted that X Corps directly allowed the Eighth Army to hold the south and quoted MacArthur in corroborating his view. Historian Li Xiaobing acknowledged X Corps' successful withdrawal from North Korea and how the Battle of Chosin "has become a part of Marine lore, but it was still a retreat, not a victory."; Eliot A. Cohen, on the other hand, has said that the "retreat from Chosin was a victory and not just a chance to live to fight again. The forces that attacked, the twelve divisions of China's Ninth Army Group, Third Field Army, did not reappear in the field until March 1951." Meanwhile, the Marines evacuated from North Korea spent January and most of February 1951 rebuilding in the relatively secure south of South Korea and "chasing guerrillas" in Pohang. They returned to action on February 21 in Operation Killer.
As for Chinese assessment on the outcome of the battle, the official Chinese history, published by PLA Academy of Military Science, states that despite the heavy casualties, the PVA 9th Army has earned its victory by successfully protecting the eastern flank of Chinese force in Korea, while inflicting over 10,000 casualties to the UN forces. Outside of official sources, however, this favorable assessment was not universally shared among the Chinese. Author Russell Spurr, while characterizing the Chinese performance as a "foul-up", reported that commander Zhang Renchu, whose 26th Corps was blamed for allowing the X Corps to escape, had threatened suicide over the outcome, while Song Shilun offered to resign his post. Yu Bin, a historian and a former member of the Chinese People's Liberation Army, states that while the destruction of Task Force Faith was the single greatest Chinese victory of the war, ultimately the PVA 9th Army Group had become "a giant hospital" while failing to destroy the numerically inferior UN forces at Chosin as planned.
Wider effect on the war
The battle was part of the PRC's intervention in the Korean War which, according to the US Army, ended the UN force's expectation of total victory, including the liberation of North Korea and the reunification of the peninsula. X Corps' evacuation, along with the Eighth Army's retreat to the 38th parallel on the western front in the aftermath of Battle of the Ch'ongch'on River, meant that the entire UN front was collapsing, and the race to reach the Yalu ended in a retreat, with the communist forces of China recapturing North Korea. The disregard by Far Eastern Command under MacArthur of the initial warnings and diplomatic hints by the PVA almost led the entire United Nations army to disaster at Chosin Reservoir and only after the formation and stabilization of a coherent UN defensive line under Lieutenant General Matthew Ridgway did the "period of retreats from an attacking, unsuspected foe cease."
On the other hand, the battle affected the PVA in two ways, both of which had the ultimate result of helping the United Nations Command secure its position in South Korea, while losing North Korea. First, according to historian Shu Guang Zhang, the belief amongst PVA commanders of their victories at Chosin and Ch'ongch'on helped convince them that they could "defeat American armed forces", and this led to "unrealistic expectations that the CPV [PVA] would work miracles.":624-5 Second, the heavy casualties caused by both combat and poor logistical support destroyed much of the PVA's eight elite divisions of the 20th and 27th Corps. Of those eight divisions, two were forced to disband,:114 With the absence of 12 out of 30 of Chinese divisions in Korea in early 1951, Roe says that the heavy Chinese losses at Chosin ultimately enabled the UN forces to maintain a foothold in Korea.:412

- The 1st Marine Division reported 604 killed, 114 dead of wounds, 192 missing, 3,485 wounded and 7,338 non-battle casualties. However, US X Corps disputed the number by only recording 393 killed, 2,152 wounded and 76 missing for the 1st Marine Division. This number is calculated by inserting the 1st Marine Division's casualty data into the X Corps' total casualty report. See Appleman 1990, pp. 345–347 and Montross & Canzona 1992, pp. 381–382.

- "Loss of the 1st Marine Division would have resulted in the loss of a substantial portion of X Corps. Instead, X Corps was withdrawn intact, while inflicting such damage upon the twelve divisions of the 9th Army Group that they were out of action until the last days of following March.

- "General MacArthur agreed that this was the decisive battle. In commenting on a study by the Marine Corps Board, he wrote: "The Marine Corps Board of Study rightfully points out that the campaign of the 1st Marine Division with attached Army elements in North Korea was 'largely responsible for preventing reinforcement of CCF forces on Eighth Army front by 12 divisions during a period when such reinforcement might have meant to Eighth Army the difference between maintaining a foothold in Korea or forced evacuation therefrom.'...""See Roe 2000, p. 412
