People's Liberation Army at Tiananmen Square protests of 1989

During the 1989 student demonstrations in Beijing, the Chinese People's Liberation Army (PLA) played a decisive role in enforcing martial law, suppressing the demonstrations by force and upholding the authority of the Chinese Communist Party. The scale of the military's mobilization for a domestic event and degree of bloodshed inflicted against civilians were unprecedented both in the history of the People's Republic and the history of Beijing, a city with a tradition of popular protests against ruling authorities dating back to the May Fourth Movement of 1919. The subject of the Tianamen protests in general and the military's role in the crackdown remains forbidden from public discussion in China. The killings in Beijing continue to taint the legacies of the party elders, led by Deng Xiaoping, and weigh on the generation of leaders whose careers advanced as their more moderate colleagues were purged or sidelined at the time. Within China, the role of the military in 1989 remains a subject of private discussion within the ranks of the party leadership and PLA. Only outside of China is the subject part of the public discourse.

Deployment of troops during the initial stages of the Protests


The student movement in Beijing in the spring of 1989 was triggered by the death of Hu Yaobang on April 15. Well before martial law was declared on May 19, the government called army troops into the city to help the police maintain order. On April 22, the Beijing Garrison's 13th Safeguard Regiment (3rd Safeguard Division) and nearly 9,000 soldiers from the 38th Army (112th Division, 6th Armored Division, engineer and communications regiments) were deployed around the Great Hall of the People during Hu Yaobang's funeral. Outside the Hall, in Tiananmen Square, nearly 100,000 students had gathered on the night of April 21 to mourn Hu Yaobang. The 38th Army was called into Beijing a second time, after the publication of the April 26 Editorial, to join Beijing Garrison troops in guarding Tiananmen Square against protesting students. Several hundred thousand students marched from campus through the city centre on April 27, but did not enter the Square. About 5,100 troops were involved in this second deployment. There were no clashes with civilians and the troops pulled out on May 5. The Beijing Garrison troops were called upon to guard the Great Hall on May 4, for the Asian Development Bank board meeting, and from May 13–17 for Mikhail Gorbachev's state visit to Beijing.

Decision to Impose Martial Law
The decision to impose martial law in Beijing was ultimately made by China's paramount leader, Deng Xiaoping, with the support of hardliners, who ruled out concessions to the students and wanted to use the military to end the demonstrations. Liberal party leaders, who opposed the use of force and favored a political solution to the crisis, were purged or sidelined. The decision also engendered some opposition within the military though the order to use force was ultimately executed.

On May 11, President Yang Shangkun met with Deng privately to discuss the causes of the student movement, the popular support it was receiving and why it was difficult to halt. Deng explained that the demand of the people against official corruption was acceptable but the motive of some people using this demand as a pretext to overthrow the Communist Party was not. He added that the Party must use peaceful means to resolve the student movement but the Politburo must be prepared to act decisively. On May 13, as the students embarked on a hunger strike in Tiananmen Square, Yang and the Party General Secretary Zhao Ziyang gave Deng a private briefing. Deng, who was the Chair of the Central Military Commission (CMC), expressed the impatience of party elders with the government's inability to end the student movement which had been active for nearly a month. He reiterated the need to act decisively.

Removal of Zhao Ziyang


On the night of May 16, the five members of the Politburo's Standing Committee, Zhao Ziyang, Li Peng, Qiao Shi, Hu Qili and Yao Yilin, along with Yang Shangkun, Bo Yibo, the deputy director of the Central Advisory Commission, held an emergency meeting and agreed to (1) solicit the views of Deng Xiaoping and (2) have Zhao Ziyang negotiate with the hunger-striking students. On May 17, the five Standing Committee members visited Deng's residence, where Deng made clear that no more concessions could be made to the students and that the time had come to call in the military to impose martial law. The Standing Committee members agreed to convene in the evening to discuss how to implement martial law. That night, the five Standing Committee members could not agree on whether to impose martial law, with Li Peng and Yao Yilin in support, Zhao Ziyang and Hu Qili in opposition and Qiao Shi abstaining. Zhao offered to resign as Party General Secretary, but was dissuaded by Yang and asked for three days of sick leave. Subsequently, Zhao Ziyang ceased to have political influence.

On the morning of May 18, the Standing Committee, minus Zhao, along with party elders Chen Yun, Li Xiannian, Peng Zhen, Deng Yingchao, Bo Yibo, and Wang Zhen, along with Central Military Commission members Qin Jiwei, Hong Xuezhi and Liu Huaqing gathered at Deng's residence. At this meeting, the leadership resolved: (1) to impose martial law on the morning of May 21, (2) hold an expanded meeting with military and Beijing government officials on May 19, (3) have Yang Shangkun make arrangements with the military to establish a martial law command, (4) explain the decision to the two remaining PLA martials, Nie Rongzhen and Xu Xiangqian, and (5) inform provincial-level party committees of the Party Center's decision. On the afternoon of the May 18, the Central Military Commission appointed Liu Huaqing as the commander-in-chief of martial law operations with Chi Haotian, then PLA chief of staff, and Zhou Yibing, commander of the Beijing Military Region, as his deputies. The military forces enforcing martial law would be drawn mainly from the Beijing, Jinan and Shenyang Military Regions. Liu, Chi and Yang Shangkun then reported to Deng that the martial law force would mobilize 180,000 PLA and People's Armed Police personnel.



By May 18, the protests in Tiananmen Square had reached one million supporters. The protests caused deep divisions within the senior party leadership as well as the ranks of the PLA. On May 17, over 1,000 men from the People's Liberation Army's General Logistics Department showed their support for the movement by marching to Tiananmen Square, and they received enthusiastic applause from onlookers.

The decision to impose martial law was initially resisted by Defense Minister Qin Jiwei. After attending the meeting at Deng's home, Qin declined to send the martial law order to the military right away, citing the need to receive party approval. Zhao Ziyang, as general party secretary, was nominally head of the party. Qin called Zhao's office, hoping that Zhao would call off the martial law order. He waited four hours for Zhao's reply, which never came. Unbeknownst to Qin, Zhao had lost the power struggle and was purged from the leadership. Qin later publicly supported the military crackdown but his authority diminished thereafter.

Martial law declared - May 20
Though martial law was scheduled for May 21, news of the impending order was leaked to the public, so the timetable was moved up. Premier Li Peng hastily announced martial law in the early morning hours of May 20. The order, declared pursuant to Article 89, Section 16 of the PRC Constitution, was to come into effect at 10:00 am in eight urban districts of Beijing.

On May 21, seven retired generals, including former defense minister Zhang Aiping, signed a letter opposing the use of force against the people of Beijing:

"Due to the exigent circumstances, we as old soldiers, make the following request: Since the People's Army belongs to the people, it cannot stand against the people, much less kill the people, and must not be permitted to fire on the people and cause bloodshed; to prevent the situation from escalating, the Army must not enter the city."

- Ye Fei, Zhang Aiping, Xiao Ke, Yang Dezhi, Chen Zaidao, Song Shilun and Li Jukui

Some sources say an eighth general, Wang Ping, also signed the letter.

Mobilization
On May 19, the Central Military Commission began mobilizing PLA units in anticipation of the announcement of martial law order. In addition to the Beijing and Tianjin Garrisons, at least 30 divisions were sent to Beijing from five of the country's seven military regions. At least 14 of PLA's 24 army corps sent troops. Reliable estimates place the number of troops mobilized in the range of 180,000 to 250,000. The scale of the mobilization exceeded that of China's border wars with Vietnam, India and the Soviet Union.

Xu Qinxian’s defiance
The extraordinary scale of the mobilization may have been motivated by concerns of insubordination. Xu Qinxian, the commander of the 38th Army, the best-equipped army corps of the Beijing Military Region, refused to enforce the martial law order. Xu said he could not comply with a verbal order to mobilize and demanded to see a written order. When told by the Beijing Military Regional command that it "was wartime" and a written order would be provided later, Xu, who had spent time in Beijing earlier in the spring, said there was no war and reiterated his refusal to carry out the order. President Yang Shangkun sent Zhou Yibing, the commander of the regional command to Baoding to persuade Xu. Xu asked Zhou whether the three principals of the Central Military Commission had approved the martial law order. Zhou replied that while Deng Xiaoping, the chairman, and Yang Shangkun, the first secretary, had approved, Zhao Ziyang, the vice-chairman, had not. Without Zhao's approval, Xu refused to act on the order and asked for sick leave. He was court-martialled and the 38th Army under his replacement mobilized to enforce the martial law order.

After Xu's insubordination, the 12th Army, which Deng Xiaoping had personally led during the Chinese Civil War, was airlifted from Nanjing. The 12th Army was the only unit mobilized from the Nanjing Military Region.

Most of the soldiers were from peasant families who had never been to Beijing and did not understand the situation they were about to confront. Many privately looked forward to their first trip to the capital and expected to be welcomed by residents. The military units from other regions spoke a different northern dialect than the Beijing citizens, adding to the confusion. The soldiers were strictly prohibited from communicating with residents. This language barrier would limit curious soldiers in finding information on the student movement other than what they have been told by their chain of command.

Some mobilized units encountered civilian protesters before reaching Beijing. On the afternoon of May 19, residents in Baoding blocked four battalions of the 38th Army from leaving the city. The 38th Army was forced to take different routes out of Baoding before reconvening on the highway to Beijing. The 27th Army was also blocked on May 19 in Baoding by crowds who chanted anti-corruption slogans and spat on the soldiers, and was forced to re-route their approach on Beijing via Zhuozhou. A detachment of the 64th Army traveling by train was blocked for two days by Tangshan students and residents who laid on the railway at Qian'an, Hebei from May 21–23.

Attempt to enforce martial law on May 20–23
On the night of May 19, advanced units from the 27th, 38th and 63rd Armies had already reached Beijing before martial law was publicly declared. But news of martial law having been leaked, students and city residents had also organized to block the troops in the outer suburbs. On May 20, military units from the 24th, 27th, 28th, 38th, 63rd, 65th, Beijing Garrison Command, 39th, 40th, 54th and 67th Armies advanced on the city from all directions. They were stopped and surrounded by tens of thousands of civilians who erected road blocks and crowded around convoys at Fengtai, Liuliqiao, Shazikou, Hujialou, Gucheng, Qinghe, Wukesong, Fuxing Road and other points outside the Third Ring Road. The 15th Airborne Corps landed at the Nanyuan Airport south of the city. Airlifts continued into Nanyuan continued for the next three days. Five helicopters of the 38th Army appeared over Tiananmen Square and dropped leaflets calling on protesters to vacate the Square. The 65th Army made several efforts to advance on Tiananmen Square from the west but were forced to pull back into the Shijingshan and Haidian Districts. The only unit that advanced into the city was the 14th Artillery Division which traveled by train from Shahe but this unit was surrounded by civilians once it reached the Beijing Railway Station.

Many troops remained surrounded for several days. During this ordeal, encounters between troops and students were mostly peaceful. Some students had trained with the 38th in the summers as members of the army reserve. In some places, troops and protesters sang traditional Maoist songs together, and residents brought the stranded soldiers food and water.

Dajing Incident
At Dajing in Fengtai District, clashes broke out between demonstrators and troops. On the night of May 19, as the 337th, 338th, artillery and armored regiments of the 38th Army's 113th Division advanced toward the Dajing Bridge, riot police clearing the way beat and injured dozens of students and residents blocking their advance. The crowd managed to pin the units on the bridge and nearby Shawo Village. Though some units retreated to a nearby middle school, other units were stranded for three days and four nights. On May 22, the regiment commissars negotiated with student leaders in Tiananmen Square to permit the units to retreat. Talks broke down when the students insisted that the soldiers leave their vehicles and weapons. At 8:00pm, the troops locked arms and pushed their way toward a nearby depot and were pelted with stones by the crowd, resulting in scores of injured soldiers. Several students trying to protect the troops were also hit by rocks. Two weeks later, troops from the 113th Division was among the first to open fire on demonstrators in western Beijing.

Pullback
On May 24, PLA troops withdrew from urban Beijing. The failed attempt to control the growing protesters in Beijing forced the party leaders to call in additional PLA units. PLA soldiers were kept in isolation and underwent re-education to instill and reinforce the belief that a turmoil in the capital needed to suppressed.

Enforcement of martial law
On June 2, Deng Xiaoping and several party elders met with the three remaining Politburo Standing Committee members, Li Peng, Qiao Shi and Yao Yilin. They agreed to clear the Square so "the riot can be halted and order be restored to the Capital." At 4:30pm on June 3, the three politburo members met with Central Military Commission members Qin Jiwei, Hong Xuezhi, Liu Huaqing, Chi Haotian and Yang Baibing, PLA General Logistics chief Zhao Nanqi, Beijing Party Secretary Li Ximing, mayor Chen Xitong, State Council secretariat Luo Gan, Beijing Military Region commander Zhou Yibing and political commissar Liu Zhenhua to discuss the final steps for enforcing martial law:


 * 1) The operation to quell the counterrevolutionary riot would begin at 9:00 pm
 * 2) Military units should converge on the Square by 1:00 am on June 4 and the Square must be cleared by 6:00 am.
 * 3) No delays will be tolerated.
 * 4) No person may impede the advance of the troops enforcing martial law. The troops may act in self-defense and use any manner to clear impediments.
 * 5) State media will broadcast warnings to citizens.

That evening, the leaders monitored the progress of the troops from headquarters in the Great Hall of the People and Zhongnanhai. Security at Zhongnanhai compound was reinforced by troops from the 1st and 3rd Safeguard Divisions of the Beijing Garrison, units of the 65th Army. Later, the 27th Army also sent units.

Covert infiltration June 2–3
On June 2, several army units were moved covertly into Great Hall of the People on the west side of the Square and the Ministry of Public Security compound east of the Square.


 * The 27th Army sent most of its troops, dressed in plain clothes, in unmarked buses that moved from Fengtai District toward the Great Hall on the night of June 2.  The movements were detected by residents, who pinned down the convoy at various points in southern Beijing, including about 2,000 near Taoranting Park.  Many troops disembarked from their vehicles and either proceeded on foot or took refuge in government buildings along route.  By the early morning hours of June 4, about 7,000 troops of the 27th Army had assembled the Great Hall of the People.  Another 800 took temporary refuge at a sports school in Dongdan.
 * The 65th Army divided its soldiers into small groups of three to five, each with one who was familiar with the city and could speak Beijing-accented Mandarin. They were dressed in plain clothes and dispatched by a variety of means from Shijingshan on June 2-- on bus, train, subway or on foot—to the Zhongnanhai Compound.  From there, the troops then moved into the Great Hall of the People via underground tunnel.  By the night of June 2, over 10,000 troops of the 65th had assembled in the Great Hall.
 * The 24th Army left its rendezvous point in Tongzhou on the night of June 2 and entered the city under cover of darkness with most troops leaving vehicles and marching on foot. They were discovered by the city merchants' motorcycle patrols, which called out to sleeping residents to form blockades.  The 24th Army did not head to toward to the Square as residents had suspected, but settled into the Ministry of Public Security Complex behind the History Museum.
 * The 63rd Army's 187th Division, dressed in plain clothing, traveled by subway from Shijingshan into the city.   At the time, the Beijing Subway did not reach Tianamen Square, so the troops emerged from stations at Qianmen, Chongwenmen and the Beijing Railway Station and walked to the Great Hall of the People.   On the afternoon of June 2, city residents noticed groups of young people streaming out of the subway, which had previously been shutdown, and rushed to block the subway exits.  Student patrols demanded groups of suspicious-looking men to produce identification, forcing soldiers in disguise to scatter.  Only two-thirds of the 187th Division managed to reach the Great Hall by 3:00 am on June 3, though the remainder eventually rejoined the unit.  The 187th spent most of June 3 guarding the perimeter of the Great Hall, sometimes in tense standoff, with student demonstrators.

Many of the troops that infiltrated the city center in disguise did not carry weapons, which had to be delivered to them in unmarked vehicles. On the morning of June 3, a bus carrying a company of soldiers in the 27th Army, dressed in plain clothes, and hidden cargo of over 100 assault rifles, five light machine guns, two radios and over 10,000 rounds of ammunition was intercepted by students at Liubukou, just west of Tiananmen Square. The students surrounded the bus and seized some of the weapons as evidence of the government's ill-intent. At 2:05 pm, over 800 soldiers and People's Armed Police in riot gear from the Beijing Garrison rushed out of Zhongnanhai to retake the weapons cache. Simultaneously, thousands of unarmed troops from the 27th and 63rd Armies emerged from the Great Hall to divert the crowds' attention. The PAP units with clubs and riot gear fought through walls of protesters to seize control of the weapons. For the first time during the 1989 Tiananmen Protests, the police fired tear gas to repel protesters.

Troop movements - June 3–4
In the early evening of June 3, state media warned residents to stay off the streets, and military units outside the city began to advance on the city from all directions.

From the West
On June 3, at 8:00pm, the 38th Army, led by interim commander Zhang Meiyuan, began to advance from military office compounds in Shijingshan and Fentai District in western Beijing along the western extension of Chang'an Avenue toward the Square to the East. This army, with 15,099 soldiers included tank and artillery units, encountered civilian protesters along Chang'an Avenue at Wukesong, Gongzhufen, Muxidi, Fuxingmen, Xidan, Liubukou and the Square itself. At about 10:00 pm, the 38th Army opened fire on protesters at the Wukesong intersection on Chang'an Avenue, about 10 km west of Square. The crowds were stunned that the army was using live ammunition and reacted by hurling insults and projectiles. Song Xiaoming, a 32-year old aerospace technician, killed at Wukesong, was the first confirmed fatality of the night. The troops used expanding bullets, which expand and fragment upon entering the body and create larger wounds. According to Wu Renhua's study, the 38th Army killed more civilian demonstrators than any other unit, despite its reputation at the time of being friendly to city residents. Fatalities were recorded all along Chang'an Avenue, at Nanlishilu, Fuxingmen, Xidan, Liubukou and Tiananmen. Among those killed was Duan Changlong, a Tsinghua University graduate student, who was shot in the chest as he tried to negotiate with soldiers at Xidan. Duan was the grand nephew of the warlord Duan Qirui, whose troops were responsible for the March 18 Massacre of 1926, the deadliest use of force against students in Beijing until 1989.

At 10:30pm, the 63rd Army’s 188th Division advanced from the western suburbs, following the path cleared by the 38th Army, and reached the Great Hall of the People on the east side of the Square. The 28th Army, which left Yanqing County in the far northwest on June 3, tried to follow this path along western Chang'an Avenue but its progress stalled at Muxidi early on the morning of June 4.

From the South
The 15th Airborne Corps and 26th Army left the Beijing Nanyuan Airport in the southern suburbs at 5:00pm and advanced north along Nanyuan Road to Muxiyuan, Yongdingmen, Zhushikou, Qianmen toward the south edge of Tiananmen Square. Paratroopers of the 15th Airborne Corps also used lethal fire along the way and, according to Wu Renhua, is probably responsible for the second most civilian casualties, after the 38th Army. Civilians deaths were recorded at Hufangqiao, Zhushikou, Tianqiao, and Qianmen.

The 54th Army left Fengtai District in the southwest suburbs at 9:50 pm. The 127th Division moved northeast through Liuliqiao, Guanganmen, Caishikou, Hufangqiao, Hepingmen, to the southern edge of Tiananmen Square. The 162nd Division moved west to Muxiyuan and then north to Majiapu, Taiping Street, Tianqiao and then Tiananmen Square.

The 20th Army under future defense minister Liang Guanglie, advanced north from Daxing County, and proceeded to the south of Tiananmen Square through Dahongmen, Yongdingmen and Zhengyangmen. At 2:00 am, about 880 soldiers from the 173rd Regiment, 58th Division of the 20th Army, were surrounded by tens of thousands of city residents outside the east gate of the Temple of Heaven in Chongwen District. About 300 were pinned against the outside wall of the Temple complex. When the regiment commander told the crowd that his troops were hungry, thirsty and tired, residents brought soda, snacks and fruit and escorted injured soldiers to the hospital.

The 12th Army was airlifted to the Nanyuan Airport on June 4 and was not deployed on the city.

From the East


At 8:00pm, the 39th Army left the Sanjianfang Military Airport in Tong County and advanced eastward toward the Square through Chaoyang and Dongcheng Districts. The 67th Army also left Tong County and moved from Dingfuzhuang, Dabeiyao, Hujialou, Jianguomen, East Chang'an Avenue to Tiananmen Square. The 14th Artillery Division departed from the Beijing Railway Station and moved toward the east side of the Square.

At 10:00pm, the first squad of the 1st Armored Division left Yangzha in Tong County and moved west along the Beijing-Tangshan Highway. Earlier, at 4:00 pm in the afternoon, this unit had been ordered to move from Sanhe in Hebei to the Beijing Garrison Command barracks at Yangzha. At Baliqiao, the first squad's advance was halted by a human chain of demonstrators and jack-knifed buses. At midnight, a vanguard unit of three APCs split from the main squad in search of a new route and moved over to the Beijing-Tianjin Highway. The main squad followed. Over the next four hours, the armored units smashed through barricaded intersections at Shilipu, Balizhuang, Hujialou, Dabeiyao, and Jianguomen, and reached the Square at about 5:00 am. The rest of the first squad followed at 5:40 am.

The second squad of the 1st Armored Division left Sanhe the night of June 3 and encountered numerous roadblocks before its advance was completely halted at Shuangjing, where residents barricaded the road with dozens of trucks and surrounded the convoy. Angry residents told the troops of bloodshed in the city and smashed the lights and machine gun mounts on some of vehicles. Scores of soldiers were injured. Division commander Xu Qingren and commissar Wu Zhongming chose not to harm civilians and stayed at Shuangjing for 13 hours from about 6:40 am to 7:40 pm, during which time residents brought food and water to the soldiers. The tank units of the second squad did not reach the Square until 1:40 am on June 5 and some of the troops arrived on June 7.

Insubordination of 116th Division, 39th Army
On the evening of June 3, Xu Feng, the division commander, switched to plain clothes and carried out his own reconnaissance of the city. When he returned, he told subordinates "not to look for him" and went into the division's communications vehicle. Thereafter, the division maintained radio silence and did not advance on Beijing, except for the 347th Regiment under Ai Husheng, which complied with orders and went to Tiananmen Square on June 4. On June 5, the rest of the division was escorted by other units to the Square. Xu Feng was later disciplined for passive resistance.

From the North
The 40th Army departed the Beijing Capital Airport at 3:35 pm and advanced on the city from the northeast via the Airport Highway, Taiyanggong, Sanyuanqiao and Dongzhimen.

The 64th Army left its assembly point at the Shahe Military Airport in Changping County north of the city and moved south along Madian, Qinghe, Xueyuan Road, Hepingli, to Deshengmen.

Converging on the Square - June 4
At about 1:30 am, the 38th Army and the 15th Airborne Corps arrived at the north and south ends of the Square respectively. The 14th Artillery Division had reached the Museum of Chinese History, on the east side of the Square, at 12:15 am. The 27th and 65th Armies spilled out of the Great Hall of the People on the west side of the Square. The 63rd Army held the east side of the Square. The 24th, 39th, 54th Armies and the 14th Artillery Division controlled the perimeter of the Square, and by 2 am, the encirclement was complete. Crowds trying to re-enter the Square from East Chang'an Avenue were driven off by gunfire. At the time, several thousand students remained huddled around the Monument to the People's Heroes inside the Square.

As the students debated what to do, Hou Dejian negotiated for safe passage out of the Square with the army. At 3:30am, at the suggestion of two doctors in the Red Cross camp, Hou Dejian and Zhuo rode in an ambulance to the northeast corner of the Square and spoke with Ji Xinguo, the political commissar of the 336th Regiment, who relayed the request to command headquarters, which agreed to grant safe passage for the students to the southeast. At 4:00 am, the lights on the Square abruptly shut, signalling the end of the army's patience. To break the students' spirits, Company No. 5 of the 2nd Bridgade, 334th Regiment knocked down the Goddess of Democracy statue at the north end of the Square. At 4:30 am, the lights relit as the soldiers moved into action.

Under the leadership of brigadier commander Wu Yunping of the 44th Airborne Brigade, troops advanced on the Monument and at about 4:40 am, shot out the students' loud speakers. By then, the majority of the students had been persuaded by Liu Xiaobo, Hou Dejian to leave the Square. The students left the Square to the southeast. Some were beaten by soldiers along the way. Army vehicles then ran over the tent city. By 5:30 am the Square was cleared. Debris was lifted out by helicopter.

At least three students were killed by lethal gunfire in and around the Square. After the Square was cleared, clashes between residents and soldiers continued for several more days. The military, especially the intelligence units, undertook to make massive arrests of "violent thugs." Some units engaged in torture.

Tank runs over students at Liubukou
At about 5:20 am, the 1st Armored Division's first squad was ordered to disperse demonstrators around Zhongnanhai. Under regiment commander Luo Gang and commissar Jia Zhenlu, eight tanks left the Square and moved west along Chang'an Avenue. Their advance was halted by several hundred students laying in the street, who refused to move despite verbal warnings and shots fired into the air. The tanks then fired military-grade tear gas, which proved unbearable to the students, who scattered. The tanks reached New China Gate of Zhongnanhai at 7:25 pm, where several stayed to guard the gate and others proceeded westward. At the Liubukou intersection, the tanks came upon thousands of students, who had just vacated Tiananmen Square, and were walking in the bicycle lane on the side of the avenue back toward campus. Three tanks fired tear gas at the students and one, No. 106, drove into the crowd, killing 11 and injuring at least nine. Luo Gang, who was promoted to the deputy division commander, claims in his memoirs that tanks under his command did not run over anyone.

Insubordination of the 28th Army at Muxidi
The 28th Army was notable for its passive enforcement of the martial law order. The unit, led by commander He Yanran and political commissar Zhang Mingchun and based in Datong, Shanxi Province, received the mobilization order on May 19. They proceeded to lead the mechanized units to Yanqing County northwest of Beijing's city centre. When ordered to enter the city on June 3, the 28th encountered protesting residents along route but did not open fire and missed the deadline to reach Tiananmen Square by 5:30 am on June 4. At 7:00am, the 28th Army ran into a throng of angry residents at Muxidi on West Chang'an Avenue west of the Square. The residents told the soldiers of the killings from earlier in the morning and showed blood stained shirts of victims. At noon, Liu Huaqing, the commander of the martial law enforcement action, ordered Wang Hai, head of the PLA Air Force, to fly over Muxidi in by helicopter and order by loud speaker the 28th Army to counterattack. But on the ground, the commanders of the 28th refused to comply. Instead the troops abandoned their positions en masse. By 5:00 pm, many had retreated into the Military Museum of the Chinese People's Revolution nearby. Of all units involved in the crackdown, the 28th Army lost by far the most equipment, as 74 vehicles including 31 armored personnel carriers and two communications vehicles were burned. The unit was later removed and ordered to undergo six months of reorganization. Afterwards, all commanding officers were demoted and reassigned to other units.

Demonstrations on East Chang’an Avenue
Later in the morning, thousands of civilians tried to enter the Square from the northeast on East Chang'an Avenue, which was blocked by rows of infantry. Many in the crowd were parents of the demonstrators who had been in the Square. As the crowd approached the troops, an officer sounded a warning, and the troops opened fire. The crowd scurried back down the avenue in view of journalists in the Beijing Hotel. Dozens of civilians were shot in the back as they fled. Later, the crowds surged back toward the troops, who opened fired again, sending the people aflight. The crowd attempted several more times but could not enter the Square, which remained closed to the public for two weeks.

Students' return to campus
Later in the morning, several thousand students walking back to campus encountered a convoy of the 64th Army's 190th Division near Xueyuan Street. The students blocked the convoy and showed their commander the body of nine-year old Lü Peng, who was killed by gunfire the night before at Fuxingmen. The sight of the child enraged the crowds. The commander ordered his men not to fire and pulled back. Later that afternoon, 27 vehicles of the 64th Army were burned near the Madian Bridge.

June 5–7
On June 5, having secured the Square, the military began to reassert control over thoroughfares through the city, especially Chang'an Avenue. A column of tanks of the 1st Armored Division left the Square and heading east on Chang'an Avenue and came upon a lone protester standing in the middle of the avenue. The brief standoff between the man and the tanks was captured by Western media atop the Beijing Hotel. As the tank driver attempted to go around him, the man moved into the tank's path. He stood defiantly in front of the tanks for some time, then climbed up onto the turret of the lead tank to speak to the soldiers inside. After returning to his position in front of the tanks, the man was pulled aside by several other individuals believed to be plainclothed government agents.

On June 7, troops from the 39th Army fired on the diplomatic apartments along Jianguomenwai Avenue after a sniper reportedly shot and killed one soldier, Zang Lijie, and wounded two others. Larry Wortzel, a military intelligence officer at the U.S. Embassy, claims that he received advanced warning of the shooting with exact hours along with buildings and floors to avoid. Wortzel believes the firings were intended to intimidate foreigners, who left Beijing en masse.

Casualties
The Chinese government has not disclosed the specific number of casualties sustained by the military during the enforcement of martial law. State-run media has reported that "tens" of soldiers, armed police and Beijing municipal police were killed and over 6,000 injured. According to Wu Renhua's study, only 15 fatalities among soldiers and armed police could be verified. Over half of these deaths were not directly caused by demonstrators:


 * six soldiers from the 38th Army, Wang Qifu, Li Qiang, Du Huaiqing, Li Dongguo, Wang Xiaobing, and Xu Rujun were killed when the truck they were riding in flipped over and caught fire at Cuiwei Road at about 1:10 am on June 4;
 * Yu Ronglu, a photographer in the propaganda unit of the 39th Army who was not in uniform while taking pictures and hit by gunfire (and counted as a "friendly fire" casualty) at about 2:00 am on June 4;
 * Wang Jingsheng, a platoon commander from the 24th Army, died of a heart attack on July 4.

The remaining seven deaths that may be counted as actual killed in action all occurred after the troops first opened fire on the crowds at 10:00 pm on June 3.


 * 1) Liu Guogeng, a platoon commander in the 63rd Army, was killed at about 4:00 am on June 4, just west of Xidan;

Rumors
In the days after June 4, rumors spread among Beijing residents that the 27th Army committed the most brutal atrocities while the 38th Army was friendly to the people. The 27th Army was believed to be led by Yang Shangkun's nephew and believed to be fanatically loyal to Yang. Its soldiers were described by residents as "illiterate 'primitives' who know only how to kill." Some soldiers were believed to have been drugged and been issued altered ammunition to increase injuries. There were reports of unprovoked shootings of unarmed civilians in the back without warning. and even reports of the 27th coercing other army troops to kill student protesters. Western media reported that the "27th Army [was] widely hated in Beijing."

There were also reports of standoffs between army units, especially the 27th. The 16th Army was said to be tasked with relieving the 38th, but wanted to do so with minimal force. The 27th, ignoring the 16th's plea, continued on violently towards Tiananmen Square. On June 6, 1989, United States officials confirmed reports involving shootings between the 16th and the 27th armies on the outskirts of Beijing. On June 7, the 38th Army was reportedly in a stand-off with the 27th and the 15th Airborne.

Another unit that rallied against the 27th was the 40th, which established good relations with the civilians along their cordoned area around the airport road. The civilians exchanged food and supplies and offered moral support to the 40th. Although many opposed the undisciplined 27th Army, none was as prominent as the 38th. Initially reluctant to obey orders to enter the city, the 38th was replaced by the 27th. However, after June 6 the 38th was sent back into Beijing to relieve the 27th from their occupied posts. Some residents of Beijing welcomed back their beloved troops and regard "The 38th Army [as] the people's army!"

The rumors inspired residents in Shijiazhuang to protest outside the headquarters of the 27th Army. Officers and family members of the 27th were subject to scorn and ridicule in their home city.

Deng Xiaoping's praise for the Army
On June 9, Deng Xiaoping made his first public appearance since the beginning of the protests in a speech thanking and praising army's enforcement of martial law. Party organizations organized citizens to study the contents of the speech. He denounced the protests as a counterrevolutionary rebellion to overthrow the party-state, which fully justified the use of force. The demonstrators' complaint about official corruption masked their ulterior motive. The steadfastness of the army, the "great wall of iron and steel" of the party and country, Deng said, had "made it relatively easy" to "handle the present matter". He named 12 soldiers who died in the action "martyrs" and recognized 13 others as "Defenders of the Republic".

Martial law was lifted on January 11, 1990.

Insubordination
During the Tiananmen repression an estimated 3,500 PLA officers disobeyed orders, In the days after June 4, Western media reported army officers being executed and generals facing court martial, though the executions have not been confirmed. In 1990, the military leadership reshuffled commanders throughout all seven military regions down to the division level to ensure loyalty. There has not been insubordination within the PLA to such an extent in the years since.

General Xu Qinxian of the 38th Army, who refused to enforce martial law, was removed from power, sentenced to five-years imprisonment and expelled from the Party. Xu Feng, Commander of the 116th Division, 39th Army, who refused to lead his troops into the city on June 3, was demoted. The entire 28th Army, which refused to obey orders at Muxidi, was ordered to undergo six months of reorganization. General He Yanran, commander of the 28th Army was court-martialed, and along with political commissar Zhang Mingchun and chief of staff Qiu Jinkai, were disciplined, demoted and reassigned to other units.

Promotions
Military officers who carried out orders vigorously were rewarded with recognition and promotion. Liu Huaqing, the commander of the martial law forces became the vice-chairman of the Central Military Commission in 1990. Chi Haotian, the deputy commander, became Minister of Defense in 1993. Liang Guanglie, the commander of the 20th Army, who succeeded Chi as the PLA's chief of staff in 1992, eventually ascended to the position of Minister of Defense in 2008. Ai Husheng, who led the 347th Regiment to Tiananmen Square while the rest of the 116th Division under Xu Feng defied martial law orders, enjoyed a series of promotions. Ai took command of the Division in 1995 and then the entire 39th Army in 2002. In 2007, he became chief of staff of the Chengdu Military Region.
