Lin Biao incident

Official Chinese narrative

According to the Chinese government, Lin Biao was made aware that Mao no longer trusted him after the 9th Central Committee, and he harbored a strong desire to seize supreme power. In February 1971 Lin and his wife, Ye Qun (who was then a Politburo member), began to plot Mao's assassination. In March 1971, Lin's son, Lin Liguo (who was a senior Air Force officer) held a secret meeting with his closest followers at an Air Force base in Shanghai. At this meeting, Lin Liguo and his subordinates supposedly drafted a plan to organize a coup, titled "Project 571". In Chinese, "5-7-1" (Chinese: 五七一; pinyin: wǔqīyī), is a homophone for "armed uprising" (Chinese: 武起义; pinyin: wǔqǐyì). Later that March, the group met again to formalize the structure of command following the proposed coup.^[3]

Mao was unaware of the coup plot, and, in August 1971, scheduled a conference for September to determine the political fate of Lin Biao. On 15 August, Mao left Beijing to discuss the issue with other senior political and military leaders in southern China. On 5 September, Lin received reports that Mao was preparing to purge him. On 8 September, Lin gave the order to his subordinates to proceed with the coup.^[3]

Lin's subordinates planned to assassinate Mao by sabotaging his train before he returned to Beijing, but Mao unexpectedly changed his route on 11 September and Mao safely returned to Beijing in the evening of 12 September. By failing to assassinate Mao, Lin's coup attempt failed.^[4]

Realizing that Mao was now fully aware of his abortive coup, Lin's party first considered fleeing south to their power base in Guangzhou, where they would establish an alternate "Party headquarters" and attack armed forces loyal to Mao. After hearing that Premier Zhou Enlai was investigating the incident, they abandoned this plan as impractical, and decided to flee to the Soviet Union instead. In the early morning of 13 September, Lin Biao, Ye Qun, Lin Liguo, and several personal aides attempted to flee to the Soviet Union^[5] and boarded a prearranged Trident 1E (registered as PLAAF 256),^[6] piloted by Pan Jingyin, the deputy commander of the PLAAF 34th division. The aircraft did not take aboard enough fuel before taking off, ran out of fuel, and crashed near Öndörkhaan in Mongolia on 13 September 1971.^[4] Everyone on board, eight men and one woman, was killed.^[5]

Pre-1994 international view of official Chinese explanation

The exact circumstances surrounding Lin's death remain unclear, due to a lack of surviving evidence. Many of the original government records relevant to Lin's death were secretly and intentionally destroyed, with the approval of the Politburo, during the brief period of Hua Guofeng's interregnum in the late 1970s. Among the records destroyed were telephone records, meeting minutes, personal notes, and desk diaries. The records, if they had survived, would have clarified the activities of Mao, Zhou Enlai, Jiang Qing, and Wang Dongxing relative to Lin, before and after Lin's death.^[2] Because of the destruction of government documentation related to Lin's death, the Chinese government has relied on alleged confessions of purged officials close to Lin to corroborate the official narrative, but non-Chinese scholars generally regard these confessions as unreliable.^[7]

Since 1971, scholars outside of China have been skeptical of the government's official explanation of the circumstances surrounding Lin's death. Skeptics assert the official narrative does not sufficiently explain why Lin, one of Mao's closest supporters and one of the most successful Communist generals, would suddenly attempt a poorly planned, abortive coup. The government narrative also does not sufficiently explain how and why Lin's aircraft crashed. Skeptics have claimed Lin's decision to flee to the Soviet Union was illogical, on the grounds the United States or Taiwan would have been safer destinations.^[7]

Western historians have contended Lin did not have either the intention or the ability to usurp Mao's place within the government or the Party.^[4] One theory attempted to explain Lin's flight and death by observing that he opposed China's rapprochement with the United States, which Zhou Enlai was organizing with Mao's approval.^[8] Because the Chinese government never produced evidence to support their report that Lin was on board the aircraft, Western scholars originally doubted Lin had died in the crash. One book, published anonymously using a Chinese pseudonym in 1983, claimed Mao had actually had Lin and his wife killed in Beijing, and Lin Liguo had attempted to escape by air. Other scholars suggested Mao ordered the Chinese army to shoot down Lin's aircraft over Mongolia.^[9]

The Chinese government has no interest in re-evaluating its narrative on Lin Biao's death. When contacted in 1994 for its comment on fresh evidence that surfaced on the Lin Biao incident after the Cold War, the Chinese Foreign Ministry stated: "China already has a clear, authoritative conclusion about the Lin Biao incident. Other foreign reports of a conjectural nature are groundless." Non-Chinese scholars interpreted China's reluctance to consider contradictory evidence of its "official" history as the result of a desire to avoid exploring any issue that might lead to criticism of Mao Zedong or a re-evaluation of the Cultural Revolution in general, which might distract China from pursuing economic growth.^[10]

Subsequent scholarship and reliable eyewitness accounts

A six-month investigation by Western scholars in 1994 examined evidence in Russia, Mongolia, mainland China, the United States, and Taiwan, and came to a number of conclusions, some of which were contrary to the official Chinese version of events. The study confirmed Lin Biao, Ye Qun, and Lin Liguo were all killed in the crash. Lin's aircraft was travelling away from the Soviet Union at the time of its crash, making the exact sequence of events before Lin's death more confusing, and casting doubt on the possibility that Lin was attempting to seek asylum in the USSR. Lin's wife and son may have forced Lin to board the aircraft against his will. Several senior leaders within the Communist Party hierarchy knew Lin and his family would flee, but chose not to attempt to stop their flight. According to this study, Lin had attempted to contact the Kuomintang in Taiwan on two separate occasions shortly before his death.^[9] The findings of Lin's attempt to contact the Kuomintang supported earlier rumors from inside China that Lin was secretly negotiating with Chiang's government in order to restore the Kuomintang government in mainland China in return for a high position in the new government. The claims of Lin's contact with the Kuomintang have never been formally confirmed nor denied by either the governments in Beijing or Taipei.

According to numerous scholars who had studied archives and records over the subsequent years, including eyewitnesses account of others involved indicated a sequence of events different from the official narrative. The whole series of events likely began on the night of 6 September 1971, when Lin Biao and his family first received word while in Beidaihe that Mao had made critical remarks of Lin during his trip in Southern China and concluded that Mao was determined to purge them in the upcoming National Congress scheduled in October 1971.^[11]

On 7 September, Liguo confided in his sister Lin Liheng (known by the nickname "Doudou") that it is "better for us...to wage a struggle than wait for our doom." Liguo presented three possible courses of action, either to assassinate Mao, or fly to Guangzhou where they could establish an alternate central committee in opposition to the central authorities in Beijing, or flee to the Soviet Union. Liheng rejected all of her brother's proposals and suggested that their father resigned from all his positions to avoid trouble, to which Liguo rebuked that their father would be detained regardless and would likely die in custody due to his waning health. After their conversation, Liheng immediately contacted the leaders of PLA Unit 8341 (Central Guard Unit), the unit responsible for her father's security but was unsuccessfully in convincing them that her brother and mother pressured her father into leaving Beidaihe for an unknown destination against his wishes. It was well-known among the security detail that the Lin family were dysfunctional.^[11]

On the night of 12 September, Lin Biao and Ye Qun were attending Liheng's engagement party in Beidaihe. Liguo, on hearing Mao's early return to Beijing immediately commandeered an Air-Force Trident from Beijing to Beidaihe, where he arrived around 8 p.m., just as the Lin family was about to spend the evening watching films with the newly engaged couple and their friends. Lin Biao had retired to his room after taking sleeping pills when Liguo arrived at their residence. Liguo told Liheng that they have to leave for "Dalian or Guangzhou or Hong Kong: anywhere depending on the situation". Ye Qun was overheard trying to convince Lin Biao to head to Guangzhou, but Lin had "remained silent" and later went to bed. Convinced that Ye Qun and Liguo were manipulating her father, she slipped away to warn the head of security to report to Beijing on the situation unfolding in Beidaihe, to which the head of security agreed to.^[11]

Premier Zhou Enlai was attending a meeting at the Great Hall of the People when an urgent telephone call came in informing Zhou that an air-force jet was at Beidaihe without authorization and had conveyed Liheng's message that Lin Biao was about to be taken to an unknown destination, possibly against his will. Zhou immediately called Wu Faxian, the head of the air force, and issued orders to ground the aircraft. When the news reached Beidaihe, it was likely that Ye Qun and Lin Liguo made the impromptu decision to escape.^[11]

In an attempt to dispel suspicion, at around 11:30 p.m., Ye Qun called the Premier and informed him Lin Biao was planning to fly to Dalian the next morning, and denied they had prepared an aircraft at Shanhaiguan. Zhou then told Ye to wait for him to travel to see Lin before they left Beidaihe (where they were staying), issued orders to neutralize potentially disruptive officers close to Lin (Wu Faxian and Huang Yongsheng), and ordered two aircraft be readied in Beijing so he could fly to Lin's residence to personally deal with the matter.^[12]

Ye then made an announcement that they were to pack quickly and head to the airport immediately. Ye Qun and Liguo packed the semi-conscious Lin into an armored limousine. At around midnight on 13 September, they pulled away from their residence, sped past a cordon of guards and headed straight for Shanhaiguan airport, 40 kilometres (25 mi) away, where their aircraft was waiting. Along the way, Lin's chief bodyguard leapt from the vehicle and was shot and wounded. The chief bodyguard later claimed that Lin had asked along the way to the airport how long it would take to reach Irkutsk. There were unresolved questions surrounding the events at the residence, such as the actions of Unit 8341, who had already been notified of the situation by Liheng and likely under the instructions of Beijing the entire time, yet made no attempt to stop Lin and his family for the next few hours. At one point, the head of Unit 8341 even mysteriously told Liheng to accompany Lin and his entourage to the airport, stating that the "Party Centre" had ordered her to do so, to which she and her fiancee refused to heed.^[11]

According to eyewitnesses, Lin Biao, Ye Qun, Lin Liguo, along with some of their aides had clambered aboard and the Trident aircraft had apparently been ordered to takeoff despite Zhou's orders. Accounts differed on whether the plane was refueled prior to takeoff. There were no co-pilot, navigator or radio operator on board. At around 12:30 a.m., with the navigation lights turned off and the airport in total darkness, the Trident aircraft took off. On takeoff, their plane grazed a fuel tanker, resulting in the undercarriage being torn away.^[11]

Lin's aircraft initially traveled southeast to the direction of Guangzhou, then returned twenty minutes later and circled the airport several times as if it were trying to land, but the runway lights had been turned off. It then flew west before turning north towards the border. It was likely that the pilot, Pan Jingyin, was told to head for Mongolia only after the group learned that Zhou had ordered Chinese airspace to be closed to air traffic. The aircraft was flying at an altitude of 300 meters to avoid radar detection. At 1:50 a.m., the aircraft left Chinese airspace.^[11]

Soviet officials and Mongolian witnesses reported the aircraft then flew north, over Mongolia and almost to the Soviet border, but then turned around and began flying south back towards China before it crashed. A Mongolian who witnessed the crash reported the aircraft's tail was on fire when it crashed.^[13] The crash occurred at around 2:30 AM.^[14]

Meanwhile, none of Zhou's instructions prevented Lin's flight, and he learned Lin's aircraft had taken off before he, himself, could fly to see Lin. Zhou had ordered all aircraft nationwide to be grounded without the written permission of Mao himself, and several senior military leaders. Wu Faxian even telephoned the control tower at Shanhaiguan airport to give a direct order to Pan not to fly under any circumstances, to which Pan assured he would not. Zhou rushed to Zhongnanhai to brief Mao of Lin's flight probably some time after 11 p.m., and asked Mao if he wanted to order Lin's aircraft to be shot down, but Mao replied that they should "let him go" and "don't shoot".^[11]

Mao was then evacuated to the Great Hall of the People where, at around 3 a.m. on 13 September, the Politburo was convened to be informed of Mao's return to Beijing and Lin's apparent flight from Beidaihe.^[11] At 8:30 p.m., 13 September, the Mongolian Foreign Ministry summoned the Chinese ambassador to Mongolia Xu Wenyi to make a formal complaint about an unauthorized entrance of a Chinese aircraft into Mongolian airspace, and reported to the ambassador that the aircraft had crashed, killing all on board. The Chinese ambassador then phoned Zhou Enlai, who then instructed the ambassador to inform the Mongolians the aircraft had entered Mongolian airspace because it had gone off course. Mao's reaction to the crash in Mongolia was unsympathetic, stating only "That's what you get for running away."^[15][16]

Only members of the investigative team itself, KGB chairman Yuri Andropov, and Soviet Leader Leonid Brezhnev were informed of the results of the forensic examination.

Mongolian investigators were the first on site to inspect the wreckage, arriving later the same day. They found an identity card belonging to Lin Liguo, confirming Lin Liguo's presence on the flight. Markings on the aircraft and surviving miscellaneous personal items confirmed the aircraft and passengers had originated from China, but the Mongolians were uncertain that any of the dead were either Lin Biao or Ye Qun. Only after inspecting the crash with the Chinese investigators did the Mongolians buried the dead onsite.^[5]

Through the Chinese ambassador, Zhou requested and received permission for Chinese embassy staff to inspect the wreckage of Lin's aircraft and the bodies, which they did on 15–16 September. The staff reported to Zhou that the aircraft had caught fire while attempting to land, and then exploded. The bodies were burnt beyond recognition. Zhou then sent additional staff to interview Mongolian witnesses of the crash, and to perform a detailed technical assessment of the crash. The report concluded the aircraft had approximately 30 minutes of fuel when it crashed, but attempted to land without activating its landing gear or wing flaps. The aircraft had overturned and caught fire while trying to make an emergency landing in the steppe. Its right wing had dragged along the ground and caught fire while aircraft remains were scattered across an area of 4 square miles.^[17]

In late 1971, a Soviet medical team secretly traveled to the crash site and exhumed the bodies, which were by then modestly decomposed. The team removed the skulls of two of the corpses suspected to be Lin Biao and Ye Qun and took them back to the Soviet Union for forensic examination. In 1972, the team concluded the skulls belonged to Lin Biao and Ye Qun (the skulls are still stored in Russian archives). In order to corroborate their findings the team returned to Mongolia a second time to inspect the body believed to be Lin Biao's. After exhuming the body a second time the team found remains of tuberculosis — which Lin had suffered from — in the corpse's right lung, confirming the Soviet identification. The Soviet team was not able to determine the cause of the crash, but hypothesized the pilot misjudged his altitude while intentionally flying low to evade radar. Judging from the fires that burned after the crash, the Soviets estimated the aircraft had enough fuel to fly to the Soviet cities of Irkutsk or Chita. All of the work and its results were kept secret from the public: outside of the investigative team, only KGB chairman Yuri Andropov and Soviet leader Leonid Brezhnev were informed. The report remained classified until the early 1990s, after the end of the Cold War.^[18]
