抗美援朝 · 志愿军入朝作战（1950–1953）The Korean War · China Intervenes (1950–1953)

On the night of 19 October 1950, more than 260,000 soldiers of the Chinese People's Volunteer Army crossed the Yalu River into Korea in three columns — without air cover, without a declaration of war, and without the enemy's reconnaissance noticing. The People's Republic of China had been founded exactly one year and eighteen days earlier. Over the following three years China would rotate nearly three million troops through a war against a sixteen-nation United Nations force fielding the most modern weaponry of the age. The war ended not with a surrender but with an armistice line — and with a peninsula divided to this day. This archive records the decision, the course of the war, and its costs, with particular attention to the people official narratives mention least: the more than 21,000 captured Chinese soldiers, and the choice they made in the prison camps with their lives on the line.

1. Before the Crossing: A State One Year Old

On 25 June 1950, the North Korean People's Army crossed the 38th parallel southward and the Korean War began. Its origins lay in Kim Il-sung's unification plan and Stalin's approval: declassified Soviet archives show Kim petitioning Stalin dozens of times for permission to attack the South, which was granted only in 1950. Mao Zedong was informed, but the timing and plan were held in Pyongyang and Moscow. On 27 June, President Truman ordered the Seventh Fleet into the Taiwan Strait — from its first week, the war on the peninsula reshaped China's entire strategic perimeter.

On 15 September, US forces landed at Incheon and the North Korean army collapsed. In early October, UN forces crossed the parallel and drove toward the Yalu. Whether China should intervene was debated fiercely in Beijing in the first half of October 1950, and the objections were concrete: the civil war had just ended, the economy was in ruins, Chinese equipment was a generation behind America's, and China had effectively no air force or navy. Mao overrode the hesitations. His reasoning included the direct threat to the industrial northeast if US forces reached the Yalu, the "lips and teeth" logic of a buffer state, and the domestic mobilisation a war would make possible. On 8 October he redesignated the Northeast Border Force as the Chinese People's Volunteer Army, under Peng Dehuai as commander and political commissar.

The decisive variable was Soviet support. Zhou Enlai's secret trip to Moscow produced a limited bargain: the USSR would supply weapons — priced as loans, not gifts — while Soviet air cover was initially promised only over Chinese territory and repeatedly delayed for operations inside Korea. Mao signalled that China would cross even without Soviet air cover. This explains two congenital weaknesses of the Chinese war effort: its ground forces fought the entire war without reliable air cover of their own, and its supply lines ran on trucks, horses and human porters under American bombing. Those weaknesses directly produced the frostbite, hunger and enormous non-combat losses recorded below.

The name "Volunteer Army" was itself a political device: China never declared war, and its soldiers were nominally "volunteers," preserving room to avoid total war with the United States. It also planted the first thorn of the later POW question — if these men were not, formally, dispatched regulars, then what Beijing was willing to claim and fight for on their behalf, once they were captured, became negotiable.

2. Timeline: From the Secret Crossing to the Panmunjom Signature

On the night of 19 October 1950, the CPV 13th Army Group — the 38th, 39th, 40th and 42nd Armies plus artillery, some 260,000 men — crossed the Yalu at Andong (now Dandong), Changdianhekou and Ji'an, marching by night and hiding by day, undetected by US air reconnaissance. China's official commemoration day for the war is 25 October, the first clash: in the First Phase Campaign, CPV forces ambushed advancing South Korean and US units around Onjong and Unsan and forced the UN Command back. The campaign set the war's basic grammar — Chinese night attacks, infiltration and close combat against American firepower and total air superiority.

The Second Phase Campaign (25 November – 24 December 1950) was the turning point. In the west, along the Chongchon River, the CPV mauled the US Eighth Army; in the east, at the Chosin Reservoir, the 9th Army Group attacked the US 1st Marine Division (see the dedicated section below). Chinese forces retook Pyongyang and reached the 38th parallel. On the campaign's first day, 25 November 1950, Mao Anying — Mao Zedong's son, serving as a Russian interpreter at CPV headquarters — was killed in an air raid at Daeyudong, aged twenty-eight. His death became part of the war's "equal sacrifice" narrative; it is also a real entry in one family's ledger of the war.

The Third Phase Campaign opened on New Year's Eve and took Seoul, but Chinese logistics snapped: units ran out of food and ammunition. General Ridgway's methodical counteroffensive pushed the CPV back north of the parallel in the Fourth Phase Campaign. In the Fifth Phase Campaign (April–June 1951), China's last great offensive, the withdrawal of the second echelon went wrong: the 180th Division of the 60th Army was cut off and encircled through failures of command and relief, and several thousand of its men were captured — the largest single loss of formed Chinese troops in the war, and a large share of all Chinese POWs taken (see the POW section below).

From June 1951 the front stabilised near the 38th parallel and the war became "fighting while talking." Armistice negotiations opened at Kaesong on 10 July 1951 and later moved to Panmunjom. The hardest knot at the table was not the demarcation line but the repatriation of prisoners (see below). The bloodiest positional battle of this phase was Triangle Hill — Shangganling in Chinese (14 October – 25 November 1952), treated in its own section. In 1953, after Stalin's death loosened every party's position and a final Chinese offensive at Kumsong, the Korean Armistice Agreement was signed at Panmunjom on 27 July 1953: signed by Nam Il for the Korean People's Army and the CPV and by Lt. Gen. Harrison for the UN Command; South Korean President Syngman Rhee refused to sign. It is an armistice, not a peace treaty — the Korean Peninsula remains legally at war. Peng Dehuai countersigned in Pyongyang on 28 July, and the ceasefire took effect at 22:00 that night.

Chinese forces then withdrew in stages, the last units leaving in October 1958. The direct Chinese war that had begun with a secret night crossing eight years earlier was over; the confrontation across the armistice line continues today.

3. Chosin Reservoir: Frostbite Took More Men Than Bullets

In November 1950, the 9th Army Group — the 20th, 26th and 27th Armies, roughly 150,000 men, previously stationed on the southeast coast for a possible invasion of Taiwan — was rushed north and into the mountains around the Chosin (Changjin) Reservoir in northeast Korea. The deployment was so hurried that many units wore the light winter kit of subtropical east China; some had not re-equipped at all. Northeast Korea was in the grip of a once-in-decades cold snap, with night temperatures between −30°C and −40°C. On 27 November the 9th Army Group attacked the US 1st Marine Division and elements of the Army's 7th Division. The outcome is almost without parallel in modern war: supplied by air and fighting behind armour and artillery, the Marines broke out in formation over eleven days and were evacuated from Hungnam port together with some 100,000 troops and nearly 100,000 Korean civilians — while the Chinese besiegers were consumed less by combat than by the cold.

Two Chinese sources give the 9th Army Group's losses, with different scopes, and this archive prints both. The official history The First War of the New China records 19,202 combat casualties, 28,954 frostbite cases (of whom more than 3,000 died of their frostbite), and over 1,000 men frozen to death — total losses of 48,156, more than half the force engaged. A statistical table of the PLA General Logistics Department's health service instead records 30,732 frostbite cases, 14,062 combat wounds and 7,304 killed, totalling 52,098. Both sources agree on the central fact: roughly thirty thousand frostbite casualties, clearly exceeding combat losses. Chinese official histories and commemorative reporting record entire companies found frozen to death at their blocking positions — remembered in China as the "Ice Sculpture Companies." This archive notes the limit of the record: the primary archival documentation for specific company designations and headcounts is thin in public sources, so we record the fact without dramatised detail. The 9th Army Group's commander, Song Shilun, concluded in his after-action reckoning that the first lesson of Chosin was logistics and preparation: troops in thin uniforms were ordered to hold blocking positions in near-arctic cold, and the bill was paid by the lowest ranks, in limbs and lives.

4. Triangle Hill: Forty-Three Days, 3.7 Square Kilometres

From 14 October to 25 November 1952, on two hills near the 38th parallel — Hill 597.9 and the northern slope of Hill 537.7, together about 3.7 square kilometres — the CPV 15th Army under Qin Jiwei (later reinforced by the 12th Army) fought the US 7th Infantry Division and South Korean forces in a cycle of positions lost by day and retaken by night. By Chinese accounting, the US side fired some 1.9 million artillery shells and dropped over 5,000 bombs onto this patch of ground in 43 days, blasting a metre or two of soil off the hilltops. The casualty figures diverge sharply by side — itself the first lesson in reading this war's history. Chinese official history records CPV casualties of 11,529 (4,838 killed, 6,691 wounded), and estimates UN casualties at 25,498; US-reported figures are markedly lower. Each side narrated the war through its own statistical scope.

In China, Triangle Hill became a cultural monument: the film Battle on Shangganling Mountain and its song "My Motherland" carried it into the memory of generations. Beyond the symbol stands a date worth remembering today: on 19 October 1952 — seventy-three years ago to the day — Chinese official history records that signalman Huang Jiguang, aged twenty-one, blocked an enemy machine-gun embrasure with his body on Hill 597.9 when his unit's attack was pinned down. Whatever verdict later generations pass on the war itself, the entries paid in individual lives are the part of the ledger least deserving to be drowned in rhetoric.

5. The Air Force That Was Not There: The Soviet Union's Secret War

The Korean War was never only a war of Koreans, Chinese and Americans. On 1 November 1950, MiG-15 fighters of the Soviet 64th Fighter Aviation Corps fought US aircraft over the Yalu — earlier than almost anyone outside the cockpits knew. By 1952 the corps fielded three fighter divisions and two anti-aircraft divisions, some 26,000 personnel including support; over the whole war, ten Soviet fighter divisions rotated through the theatre and flew more than 60,000 sorties, contesting the airspace between the Yalu and the Chongchon — the corridor American pilots named "MiG Alley."

The participation was wrapped in extreme secrecy. Soviet pilots wore Chinese uniforms, their aircraft carried Chinese markings, they were forbidden to speak Russian on the radio after takeoff, forbidden to pursue south of the Pyongyang–Wonsan line, and forbidden to fight over the sea — all to prevent a captured pilot from exposing the truth. The other side colluded in the silence: US signals intelligence knew perfectly well that the voices in the MiGs were Russian, but Washington chose not to say so and not to escalate. Both superpowers feared turning a "limited war" into a third world war, and so jointly maintained a public secret for decades, until post-Cold War Russian archives brought the 64th Corps fully into the open. For China, the Soviet manner of participation is an instructive footnote to the alliance: the partner who supplied money and guns kept its risks carefully capped; the partner who supplied the men absorbed all the rest.

6. Where the Prisoners Came From: Former Nationalist Soldiers, the 50th Army, and the 180th Division

To understand the choices those prisoners later made in the camps, begin with a question the official narrative seldom opens: who, exactly, were the rank and file of the "Volunteers"? Much of the answer lies in the civil war's ledger. The People's Liberation Army replenished itself by the formula "capture, replenish, educate, fight" — captured Nationalist soldiers received brief political education and were folded directly into PLA units. These men were called "liberated soldiers," and their scale was stated plainly by the Communist leadership itself: Zhu De said in August 1948 that "60 to 70 percent of our army are liberated soldiers"; Zhou Enlai put the share in April 1949 at 50 to 80 percent depending on the unit, averaging 65–70 percent, and at 70–80 percent in June 1950. Party historian Jiang Linping counts some 2.8 million captured Nationalist soldiers converted into the PLA between July 1946 and 1949 (Jiang Linping, "The Emergence and Scale of the 'Liberated Soldiers' Group," Dang de Wenxian, no. 3, 2012). The scope must be stated: these figures describe the PLA of the late civil war and the founding of the PRC. The armies sent into Korea had since been reorganised, partially demobilised and topped up with new recruits, so the proportion had shifted — and no reliable figure exists for the Volunteer Army as a whole. Roy Appleman, the US Army's historian of the war, estimated that in many Chinese divisions "perhaps 30 percent" of the troops were former Nationalist soldiers. This archive goes no further than this: former Nationalist personnel made up a substantial share of the Chinese force in Korea — and many of them, captured once in a civil war and issued a new uniform, were sent into a second war.

The most famous whole formation rebuilt from a Nationalist army was the 50th Army. Its predecessor was the Nationalist 60th Army, a Yunnan clique force under Zeng Zesheng. Besieged in Changchun through 1948, with the city's garrison and civilians starving for months, Zeng led the 60th Army over to the Communists on 17 October 1948 — some 26,000 officers and men, by the Northeast Field Army headquarters' announcement of 1 December 1948. On 2 January 1949 the force was redesignated the PLA 50th Army, with Zeng still in command. In October 1950 it entered Korea with the first wave. In the Fourth Phase Campaign it held the banks of the Han River for some fifty days; Chinese official war history credits it with 11,000 enemy killed, wounded and captured — the hardest fight this former Nationalist army ever fought for its new government. Its own losses are recorded in conflicting figures: one account gives 10,033 men; another claims the army shrank from over 33,000 on entry to barely 10,000 after the first four campaigns. Neither figure has been traced to a primary military-history source, and this archive prints both as disputed (marked "unverified") rather than adopt either. What is certain is that after the Han River defence the 50th Army was pulled back in March 1951 to rest and refit. An army that two years earlier had been holding a city for the Nationalists bled on the Han for the new regime — a fact that says more about that generation of ordinary soldiers than any discussion of their composition on paper: they rarely got to choose whom they fought for.

The 50th Army is routinely confused with the 180th Division, destroyed in the Fifth Phase Campaign — and the widespread claim that the 180th was "a former Nationalist uprising unit" is a mistake produced by identical numbers, which this archive corrects here. The PLA 60th Army, to which the 180th Division belonged, had nothing to do with Zeng Zesheng's Nationalist 60th Army beyond sharing the numeral. The 180th Division grew out of local forces of the Taiyue Military District: raised as the 24th Brigade on 1 August 1947 and redesignated the 180th Division in February 1949 before Taiyuan, under the 60th Army — a unit of the old base areas (lineage per Yan Kefu, "My Views on Questions Concerning the Defeat of the CPV 180th Division," Journal of Military History Studies, no. 1, 2014, written from the 60th Army's military-history materials, the division's own self-examination report and a CPV Party Committee circular). No reliable source gives the proportion of "liberated soldiers" inside the 180th Division. The 60th Army's political commissar, Yuan Ziqin, wrote in his post-mortem that the division's "political foundation was not thick" — a political verdict in the language of the time, not a composition statistic, and it cannot be converted into a percentage. The division matters not for its composition but because it suffered the heaviest losses of any Chinese division in the war, and because its destruction was documented in unusual detail by the internal reports of the time: it was a catastrophe written by command confusion.

On the evening of 16 May 1951, the second stage of the Fifth Phase Campaign opened. The 60th Army was parcelled out: its 179th Division was attached to the 15th Army and its 181st Division to the 12th Army, leaving the entire task of pinning the US 1st Marine Division and the US 7th Division to the 180th Division alone — some 11,000 men, a strength inferred from the 60th Army's entry returns; no direct divisional roster survives in the sources. On 21 May at 16:00, CPV headquarters ordered a general withdrawal to begin on the night of the 23rd. The 3rd Army Group, on its own authority, advanced the withdrawal to the night of the 22nd — then reversed itself on the morning of the 23rd, ordering its units "not to withdraw for now, but to cover the evacuation of the wounded first." By then the neighbouring armies had already pulled north on the 22nd–23rd, and the 180th Division's flanks were bare. On the night of the 24th, the division crossed the North Han River without bridging equipment, wading in lines along improvised wires; more than 600 men were swept away by the current in a single night. On the afternoon of the 25th, relaying the army group's two contradictory orders, the 60th Army had division commander Zheng Qigui recall the 538th Regiment, which had already set out. At dawn on the 26th, US and South Korean forces occupied Mapyeong-ri and Ganchon, and the 180th Division was encircled.

The breakout on the night of the 26th is the darkest page of the disaster. In organisational chaos, more than 5,000 men straggled and scattered in a single night without heavy fighting — the words of the CPV Party Committee's circular of 19 July 1952. By the morning of the 27th, at Yingfeng, fewer than 1,000 men remained in formed bodies. Zheng Qigui, his deputy Duan Longzhang and chief of staff Wang Zhenbang made their way back by about 1 June; the 539th and 540th Regiments returned in batches of a thousand-odd each. The division's acting political commissar and political department director, Wu Chengde, led a group of wounded men behind enemy lines for more than four hundred days before his capture in July 1952 — the highest-ranking Chinese prisoner of the war, whose later fate is told in Section 8. Zhang Zeshi, a trainee propaganda officer of the 538th Regiment, was captured in the same collapse; the POW memoirs he later wrote are among the key texts for Sections 7 and 8 of this archive.

Two internal Chinese statistical accountings of the division's losses survive, and this archive prints both. The division's own July 1951 table of breakout losses records 7,644 men — 1,616 wounded, 456 killed, and 5,572 "circumstances unknown" (straggled, captured, scattered) — with a remaining strength of just over 4,000 including rear elements and the wounded. The 60th Army's military-history table for the whole Fifth Phase Campaign records 8,107 — 1,808 wounded, 524 killed, 5,775 missing. The common lesson of both tables is that the killer was not battlefield death but "missing" and "circumstances unknown." The exact number captured cannot be separated out of these figures: Chinese accounts drawing on the POW exchange records give about 4,000 captured; Western scholarship commonly estimates about 5,000. The 3rd Army Group's early report of 3 June 1951, estimating only 500–600 captured, was overtaken by the later exchange records and is not used here. The 3rd Army Group lost 39,558 men across the Fifth Phase Campaign; the 180th Division's encirclement accounted for roughly a fifth of that — the heaviest divisional loss of the campaign. In October 1952, CPV headquarters rebuilt the division from three cadre regiments (over 5,000 men) transferred from military districts in Sichuan plus 1,450 veterans, combined with its remnants; claims that its designation was abolished are false.

Division commander Zheng Qigui (1913–1990), a native of Jinzhai, Anhui, had joined the Red Guards in 1929, served in the Fourth Front Red Army, and spent most of his career in political work before taking command of the division on 30 May 1949. Yan Kefu's study links his weakness in military command to that career path — he had never held senior military command. After the disaster Zheng was removed from his post and demoted (accounts differ — "probation within the Party for one year," "reduced two grades to quasi-divisional rank" — and no original punishment document has been published; this archive confirms only removal and demotion). He returned to China in 1953 to posts in the Jilin Military District, was made colonel in 1955, and died in Hefei on 26 January 1990. The popular claim that 60th Army commander Wei Jie was dismissed over the affair is likewise contradicted by the material Yan cites: in 1952 Zhou Enlai told Wei Jie to his face that "the 180th Division's failure was not your responsibility." Even at the time, accountability for the disaster was a muddled account — and its bill, in the end, was paid by five thousand-odd privates listed as "circumstances unknown."

7. The Prisoners: Twenty-One Thousand Men Vote a Second Time

This archive regards the prisoner-of-war chapter as the most under-told of the entire war. Roughly 21,374 Chinese soldiers were captured during the war (sources cluster around 21,000). The armistice negotiations, which ran from 1951 to 1953, stalled in their final phase on almost a single question: how prisoners would be repatriated. Under pressure from the Truman administration, the UN side insisted on "voluntary repatriation" — no prisoner would be forced back to a side he refused to return to; the Chinese and North Korean side demanded full repatriation under the Geneva Conventions. General Mark Clark, who signed the armistice for the UN Command, later wrote that he had gained the unenviable distinction of being the first US commander to sign an armistice without victory — and the core of the long delay was precisely this: for the first time, the individual prisoner's will was placed opposite the will of his state. In The Hijacked War (Stanford University Press, 2020), historian David Cheng Chang estimates that the nearly two extra years of fighting over the POW question cost some 12,300 additional American dead and at least 90,000 Chinese casualties — an estimate this archive cites with its source attached.

In April 1952, the UN Command screened prisoners in the camps on Koje-do (Geoje) Island and elsewhere, asking each man whether he would accept repatriation. The result surprised every government involved: a majority of Chinese prisoners said they refused to return to the mainland. But the screening was anything but a quiet ballot. The converging picture from archives and memoirs is this: the camps' internal administration was held by pro-Taiwan prisoner cadres — former Nationalist officials and soldiers — who used forced tattooing (slogans such as "Oppose Communism, Resist Russia" carved into prisoners' skin), beatings and starvation to punish men who chose repatriation; prisoners who insisted on going home were beaten, maimed, and in documented cases killed. On the other side, clandestine pro-communist organisations inside the wire answered with assassinations of "traitors." Camps 71, 72 and 86 on Koje-do saw the worst violence; in May 1952 prisoners even seized the camp commandant, Brigadier General Dodd, as a hostage. In other words, some twenty-one thousand soldiers, most of them around twenty years old, registered their destination between the fists, knives and underground cells of two coercive systems. That record can neither be romanticised as a pure free vote nor erased as wholly coerced: coercion explains some men, but it does not explain why, in the final 1953–54 phase under a neutral-nations repatriation commission — when any man could still change his answer under neutral guard — the overwhelming majority did not change it.

The two groups' later lives are the true ending of this chapter. The 7,110 who returned to the mainland were first welcomed as heroes, then subjected to intensive political screening: the great majority were expelled from the Party and the army, faced discrimination in job placement for decades, and were persecuted again in the Cultural Revolution. Only in 1980 did a central directive rehabilitate them, acknowledging that those who had committed no "acts of betrayal" while captive should have their standing restored — twenty-seven years after they came home. The 14,235 who went to Taiwan were folded into the Nationalist armed forces; showcased as propaganda symbols, they simultaneously carried the indelible mark of "former communist troops" and lived under surveillance and unequal treatment. Only after Taiwan lifted its ban on mainland family visits in 1988 could some of them return to their home villages — as old men. Twenty-one thousand ordinary soldiers were pushed, at twenty, to one of history's crossroads. Their choice, and its price, deserve a longer record than a slogan.

8. The Returnees' Thirty Years: The Changtu Screening, the Campaigns, and the 1980 Rehabilitation

First, reconcile the ledger of destinations from the previous section. The 7,110 who returned to the mainland (Chang's The Hijacked War counts 7,109 men and one woman) came home in three batches. In "Little Switch" (20 April – 3 May 1953), the UN Command handed over 1,030 sick and wounded Chinese prisoners. In "Big Switch," beginning 5 August 1953, 5,640 were repatriated directly. The remaining 440 returned after the Neutral Nations Repatriation Commission's custody and explanation period (15 October – 23 December 1953): only 137 of them formally chose repatriation during the explanations proper; the rest included 70 men who asked the Indian custodian force to send them home in the final two days, 20–21 January 1954 (Chang's accounting). It is worth noting that the commonly cited total of 21,374 captured is exactly the sum of the three armistice-exchange figures — 1,030 + 5,640 + the 14,704 handed to the Neutral Nations Commission — which suggests that 21,374 is the total awaiting disposition at the exchange point, not a cumulative count of everyone ever captured; a cumulative figure would also have to include those who died or escaped in captivity, for which no reliable statistics exist. American figures differ again: the lists published in December 1951 recorded 20,700 Chinese prisoners, revised to 20,720 in January 1952 (US State Department, Foreign Relations of the United States, 1951, vol. VII) — a difference of date and classification. The Taiwan figure likewise exists in several accountings: 14,235 were released to the UN side at the close of the Commission's work; Chang's cumulative total of those who went to Taiwan is 14,342, including 142 seriously wounded men flown directly to Taipei on 23 January 1954; Taiwanese records put the number reaching Keelung on 23 January at 14,209. Only 12 Chinese prisoners chose neutral countries — of the 88 men who left with the Indian custodian force, the other 76 were Koreans — and Chang's 2020 journal study traces those 12 to 1958: two had returned to China, six had gone to Brazil, two to Argentina, and two remained in India. No reliable total exists for Chinese deaths in captivity; the surviving fragments include the 56 Chinese prisoners shot dead in the Cheju Island camp incident of 1 October 1952, recorded in the British House of Commons Hansard of the time.

What awaited the 7,110 was first a welcome, then a screening. They were received at Kaesong and feted as heroes along the way home; but from mid-November 1953 they were concentrated at the "Volunteer Army Returned Personnel Management Office" in Changtu County, Liaoning, for months of political screening. The central guideline ran to twenty characters: "warm concern, patient education, strict screening, prudent handling, proper placement." The process moved through four stages — mobilising education, self-examination and confession, conclusion, and placement. The Management Office circulated the line that "a Communist Party member cannot be taken prisoner," and required every man to confess his "act of surrender" — the screening began not from the facts but from the premise that capture itself was guilt (per He Ming, Loyalty: The Plight of Returned Volunteer Army POWs, Chinese Literature and History Press, 1998; the author had worked in the returned-personnel apparatus).

The conclusions hardened abruptly in early 1954. Before February 1954, about 80 percent of the men had their Party, Youth League and military status restored. After March 1954, the line turned severe. The final distribution, from He Ming's investigation as cited by scholar Pingchao Zhu, is stark: of the returnees who were Communist Party members, 91.8 percent were expelled from the Party — the denominator is Party members, not all returnees, a point many retellings get wrong. On a statistical base of 6,064 men: some 700 were stripped of military status outright; more than 4,600 had only their pre-captivity service recognised; only thirty-odd officers of battalion level and above, together with a few disabled men, received civilian job placements. Everyone else was demobilised to his home village to farm, his file annotated "use under control," and a small number were convicted as "spies." What accounts for the gap between the 6,064 base and the 7,110 total is not explained in the available sources (marked "unverified").

Individual cases give the distribution a human shape. Wu Chengde — the highest-ranking prisoner of the war — was expelled from the Party and the army in June 1954 and assigned as deputy director of a state farm at Dawad in Panjin, Liaoning. He petitioned for nearly thirty years before his rehabilitation in March 1982, when his Party membership was restored and he was granted the treatment of a senior military cadre; he died in 1996. Jiang Qingquan, one of the prototypes of Wang Cheng, the hero of the film Heroes' Children who famously calls artillery fire onto his own position, was the radioman knocked unconscious and captured after doing exactly that on 18 April 1953 at the battle north of Seokhyeon-dong — after repatriation he was persecuted for decades and lived under an assumed name for more than half a century, before finally being rehabilitated and recognised (per Global People magazine, 2013).

No reliable record has been found of collective processing of returned POWs specifically under the 1955 Campaign to Eliminate Counterrevolutionaries (marked "unverified") — but the political campaigns that followed did not pass them by. Zhang Zeshi came home to be "wrongly branded a capitulator" and expelled from the Party, was made a "rightist" in the Anti-Rightist Campaign, and a "traitor" in the Cultural Revolution; his case was fully corrected only in 1981. Yu Jin's Misfortune (1992) records that during the Cultural Revolution a "considerable number" of returned prisoners were struggled against and persecuted, and that more than a few killed themselves; one veteran's words were preserved: "We were treated worse than labour-camp inmates." No source offers a total for those persecuted to death or driven to suicide. One documented case is Li Zhengwen of Sichuan: in 1982, as the rehabilitation policy was being implemented, two cadres asked him to write his autobiography; believing a new round of persecution was beginning, he hanged himself (Yuan Ling, "The Strategist"; Southern Weekend, 2014). The news of rehabilitation arrived — but thirty years of fear had killed the man first.

The turn came after the returned prisoners, as a group, petitioned the National People's Congress. In 1980 the Central Committee of the Communist Party issued Central Document No. 74 of 1980, the "Opinion on the Review and Handling of the Question of Returned Volunteer Army Prisoners." One detail is commonly misstated, and this archive corrects it: this was a Central Committee document, not a General Political Department one; the General Political Department was the organ that then implemented and transmitted it. The document's exact month of issue does not appear in published records. It reversed the verdict on these men at the level of principle, stating that they had "always turned their hearts toward the motherland and, under the organisation and leadership of steadfast Party members and revolutionary cadres, waged resolute struggle against the enemy and fought to be repatriated" (as quoted in Zhang Zeshi's writings). On that basis, most returnees had their Party membership restored and were rehabilitated. Implementation took years: on 15 October 1981 the General Political Department transmitted the Shanxi Military District's report on the review; on 27 October 1981 the General Logistics Department's finance arm issued a notice reissuing demobilisation allowances — the only economic remedy that can be verified; whether Document No. 74 provided for back pay is unverified. In 1982 the Ministry of Civil Affairs and the General Political Department jointly inspected how the document had been carried out. Writing in Yanhuang Chunqiu in 2013, Zhang Zeshi pointed out that political rehabilitation changed little in most returnees' material lives: the majority lived out their years in poverty and illness and died early.

Zhang Zeshi (1929–2021) deserves a paragraph of his own. Born in Shanghai, he entered Tsinghua University's physics department in 1946 and joined the Party in 1947. In 1951 he went to Korea as a trainee propaganda officer of the 538th Regiment, 180th Division; in late May he was wounded and captured in the division's collapse, and held in Camp 86, where he served as chief representative and interpreter of the faction determined to go home. He was among the final batch of 440 repatriated in 1954. At home he was expelled from the Party, made a rightist, and branded a traitor in the Cultural Revolution, before full correction in 1981. After that, he spent the rest of his life on one task: writing this population back into the record — I Returned from an American Concentration Camp (1989), Notes of a Prisoner of War (1994), the edited volume Eyewitness Accounts of the American Concentration Camps (1995), and My Korean War (Current Affairs Press, 2000; revised as My Korean War: A Volunteer Army POW's Memoir at Sixty Years, Jincheng Press, 2011). It should be stated plainly: Document No. 74 grew out of the returned prisoners' collective petition, and Zhang Zeshi's personal role in that petition is not documented in reliable sources — this archive does not cast him as the lone petitioner-hero. What he did was longer-lasting: he gave the twenty-one thousand captured and the seven thousand who came home their first book-length record. He died in Beijing on 18 March 2021.

Across the strait, the fourteen thousand lived a differently arranged life. On 23 January 1954 the first "anti-communist righteous warriors" reached Keelung aboard US naval vessels; the date was made "123 Freedom Day" (renamed World Freedom Day in 1993), and by 29 January over 14,000 had arrived. They first passed through ideological remoulding and vetting directed by Chiang Ching-kuo — blood-written letters, loyalty oaths, self-confessions; 4,410 men with Communist Party or Youth League backgrounds were noted in their files, and 15 were sent for "re-education." Thereafter 97.4 percent were inducted into the Nationalist armed forces (Taiwan-side survey figures). Between the propaganda title of "righteous warriors" and actual treatment there was a gap: the oral history of Zhang Yifu, who went to Taiwan, records that their uniforms carried a distinguishing "员" ("member") insignia — uncannily like the "PW" marks of the prison camps — until 1957, that their speech was long monitored, that one man was jailed for six months for signing a postcard with the words "fellow sufferer," and that news of hangings and well-jumpings circulated continually (Academia Sinica's Oral History, no. 13, 2013). The same Taiwan-side survey supplies the figure that closes the loop with Section 6: of those who went to Taiwan, 9,234 — about 66 percent — had originally been Nationalist servicemen. Captured, re-uniformed, captured again, and made to choose again: that is the full trajectory of their generation. After Taiwan opened mainland family visits for veterans in November 1987, some of them at last saw their home villages again; no statistics on the visits or on resettlement on the mainland have been found (marked "unverified").

9. The Ledger of Costs: Three Sets of Numbers, and the Fiscal Bill

How many Chinese soldiers died in this war? The question has three standard answers, and the differences are themselves part of the history. This archive prints all three, with their scopes, and lets readers judge:

The gaps between these figures come mainly from scope: whether only battle deaths count, or also deaths from cold, disease, accidents and the later reclassification of the missing; whether unit archives or post-hoc compilations govern. This archive's position is to place the three numbers on the same table rather than choose one on the reader's behalf.

The fiscal and institutional bill belongs in the same ledger. By Chinese official-war-history and standard scholarly accounts, direct war expenditure consumed roughly a third of state budgetary spending over the war years (estimates vary by scope). The Soviet weapons were supplied on credit, and China repaid the debt, principal and interest, by the mid-1960s — the hardest repayment years coinciding with the Great Famine. The war also stopped China's diplomatic clock for twenty years: total confrontation with the United States and exclusion from the United Nations until 1971, while the Seventh Fleet's entry into the Taiwan Strait froze the Taiwan question into its modern shape. At home, wartime mobilisation ran in the same window as the Campaign to Suppress Counterrevolutionaries and land reform; the general-mobilisation system built around "Resist America, Aid Korea, Protect the Home and Defend the Nation" shaped Chinese governance for three decades. Any accounting of this war that stops at the front line is incomplete.

10. What the Peninsula Paid: Civilians and the Divided Families

The war's battlefield lay entirely on the Korean Peninsula, and Koreans paid the largest share. Scholarly estimates of civilian deaths span a range: Bruce Cumings puts Korean civilian deaths at roughly two million; Guenter Lewy estimates between two and three million peninsula-wide; Charles Armstrong estimates that North Korea lost some 12–15 percent of its pre-war population. South Korea's defence ministry counts more than 750,000 southern civilians killed by violence and roughly one million missing. The US Air Force dropped some 635,000 tons of bombs in three years — more than in the entire Pacific theatre of the Second World War — systematically destroying North Korea's major cities and irrigation infrastructure. These figures rest on differing methods and cannot be made precise; this archive prints the ranges side by side and adopts no single number as verdict.

The second, still-running cost is the divided families: an estimated ten million people were separated from relatives by the war and the division. Inter-Korean family reunions, held intermittently from 1985 to a last round in 2018, came too late for most: the majority of registered South Korean applicants have already died. For them, 27 July 1953 was not the beginning of peace but the day a line cut their remaining lives in two. More than seventy years after the armistice, the peninsula still has no peace treaty.

11. Narrative, Memory, and the Unsettled Arguments

The war's place in Chinese public memory has swung more than once. In 1951, Wei Wei's battlefield dispatch "Who Are the Most Beloved People?" fixed the official frame for decades: selfless soldiers, a just war to defend the home. In the reform era, with US–China rapprochement and shifting domestic priorities, commemoration cooled to a decennial rhythm. In 2020 the seventieth anniversary was marked at a markedly higher pitch, and the following year the film The Battle at Lake Changjin took some 5.77 billion yuan at the box office to become China's highest-grossing film at the time — the war's memory re-mobilised as core material for patriotic education. In the United States the same war is remembered as "the Forgotten War"; in South Korea, as the founding trauma of national survival and division. Three countries keep three mutually untranslatable memories of one war.

At least two disputes remain open, and this archive records them without adjudicating. First, the 1952 Chinese and North Korean accusation that the United States waged germ warfare, which Washington denied: Soviet archival materials published by the Cold War International History Project in 1998 indicate elements of the evidence were fabricated, and many scholars conclude the charge cannot be sustained, while China's official position maintains it to this day — the matter is unresolved (marked here as "unverified · disputed"), and this archive records it in a single passage, without a verdict. Second, the historical verdict itself: the official narrative stresses a war that "defended the home, built national and military prestige"; a body of scholarship replies that the war began as Kim Il-sung's invasion approved by Stalin, that China paid the bill for it, that intervention cost China its 1950 window on Taiwan and bought twenty years of blockade. These views coexist in the scholarly record; this archive prints them side by side.

Our Editorial Note

To judge a war, ask first who decided, then who paid. The decision to intervene was taken at the very top in Beijing, and its geopolitical logic was not baseless. But the payers are identifiable: the companies frozen at their positions at Chosin in thin uniforms; the men who took and retook 3.7 square kilometres of hill at Triangle Hill; the twenty-one thousand young prisoners who, between tattooing needles, fists and two systems of terror, had to register a destination; the two to three million dead civilians of the peninsula and its ten million divided family members. This archive lingers on the POW chapter because it punctures the most convenient assumption of war narrative: when more than fourteen thousand captured soldiers, at the last moment when they could still change their minds, still chose not to go back, they were delivering a verdict not on a battle but on the system they had marched out of. A state can order its soldiers to die for it; it has a harder time explaining why those soldiers preferred a strange island to coming home. Record the numbers, the dates and the choices, and let later generations judge — that is what an archive is for.
