Sichuan invasion

The Sichuan Invasion, also known as the Chongqing Operation, Chongqing Campaign or Operation 5, was the Imperial Japanese Army's failed plan to destroy the Chongqing-based Chiang Kai-shek government during the Second Sino-Japanese War. It was to be a stepping stone for Japan's final control of the mainland. The operation started in spring of 1942, after the first phase of operations had been concluded in south China, and continued through spring of 1943. The operation is noted for Japan's sustained bombing of cities in central west China.

The Basic Plan

The basic plan was to make a multi-front breakthrough to Sichuan from northern Shanxi, central Hubei and southern Hunan. Heavy aerial support and bombing of Chongqing supported the advance of Japanese Army and collaborationist forces. Japanese Navy patrol boats from the Yangtze river provided further bombardment. Chiang Kai-shek discussed the invasion in his book ''Soviet Russia in China'', stating:

The Imperial General Headquarters sent the order for drawing down 16 divisions and logistics support units from Japan reserves, Manchukuo and Southern Areas to reinforce the Japanese expeditionary forces in central China area, to prepare the principal force of ten divisions in south Shanshi and other support group conformed by six Divisions of Ichang in Hubei amongst other Divisions located in Changde, in Hunan, for striking Sichuan and the occupation of Chongqing in September 1942.

By coincidence, September 1942 was also the time when the Wehrmacht was closing in on Stalingrad. The actual invasion involves Japanese units first occupying Wanxian, from where the Japanese could advance to Chongqing-proper in . To cut off the escape routes of Chinese refugees, the occupation of North Guizhou was planned, which could be used to stage an attack on Chengdu through Yibin. The north Japanese army division had the option to either advance towards south Shaanxi to capture Xian, or towards Hangzhong to take Chengdu directly. Alternatively, Japan could have utilized airborne forces to cut off Chinese escape routes and take the Chongqing metropolitan area directly.

Interests in Sichuan region

Both Chiang Kai-shek and suspected that the intense bombing of Chongqing by the and the was to support the diversionary Japanese operations against metropolitan Chongqing, as part of the invasion of Sichuan. It was also possible that the Japanese army hoped that a terror campaign against Chongqing would force the Chinese authorities to break from the and make a separate peace with Japan.

Sichuan Invasion

Japanese plan

According to General Chiang Wei-kuo, should the invasion be successful, the Japanese might have intended to put Wang Chingwei's puppet regime in charge of Chongqing. The Japanese might also persuade Chiang Kai-shek to join Japan's Greater East Asian Co-Prosperity Sphere and to even assist in a future Japanese offensive against the Soviet Union in Siberia and Central Asia. Another possibility was the installation of a Japanese civilian or military Governor-General to administer the area as an Imperial Japanese Army fief in mainland Asia, which could later be expanded to include Tibet and Xinjiang as well.

Factors affecting the Sichuan Invasion

Due to opposition against Japan from other Allied countries, the Sichuan Invasion was not enthusiastically carried out. In particular, the United States' counter-offensive against Japan heavily undermined the possibility of an invasion. Chiang Kai Shek stated:

But in June 1942, Japanese forces suffered the humiliating defeat in the Battle of Midway, and in August the U.S] forces initiated the counteroffensive against the Solomon Islands, with a landing at Tenaru River, Guadalcanal . The Japanese suffered frequent losses at the end of September 1942, and decided to delay the implement of invasion plan for Sichuan. Later in November, the Japanese forces having been totally defeated in Guadalcanal, , the situation was turned around, with Japan losing all possibility to transfer with impunity its forces in the area . At the end of 1942, the planning for the Sichuan Invasion was suspended.

Last operative attempt to invade

However, the Japanese Imperial General Headquarters was still in favor of an invasion. Hence the Japanese China Expeditionary Army produced a new plan for the capture of Sichuan, which was based on the previous 1942 plan. The May 1943 "Battle of West Hubei" was part of this new attempt to advance to Sichuan.

Nevertheless, by then the Nationalists Chinese Armies gained the support of the "Flying Tigers" of the United States, which was commanded by General Claire Chennault. In subsequents battles, the Japanese army suffered defeats in hands of the Nationalists Chinese Armies. In light of these defeats, the Japanese forces was obliged to occult for six months before a new offensive could be mounted. During this period the Chinese Army sent seven Army envoys to Yunnan and India to clear the China-Burma route.

In fear of Chinese reinforcements through the cleared route and having sustained much losses in the Battle of Changde, the Japanese army switched their attention to Yunnan to prevent future Chinese counter-offensives from that area.

Shu (state)

Shu was an ancient state in what is now Sichuan, China. Shu derived its power from the Chengdu Plain, with its territory primarily in the central and western Sichuan basin, as well as in the upper . Shu was conquered by in 316 BC. Its capital was at Chengdu.


Shu is first mentioned in history as an alliance member with in overthrowing the Shang Dynasty, taking part in the Battle of Muye. In the archaeological record, post-Muye Shu showed a culture with advanced military technology equivalent to that of the Zhou states; however, Shu military technology stagnated for the next several centuries, mirrored by its lack of mention in recorded history.

Legend states that Shu was ruled at one time by the mythical king, Duyu , and his descendants. Shu was later ruled by the Kaiming kings. During the later half of the Spring and Autumn Period, Shu culture increasingly borrowed from and cultures; for example, Shu copied the practice of boat coffin burials from Ba. The archaeological evidence also shows that Shu interacted with the cultures to the south in Yunnan and Guizhou.

During the Warring States Period, Qin and Chu increasingly encroached on the Han river valley. Clashes with Shu inevitably began to arise; Shu fought Qin in 387 BC and Chu in 377 BC.

Conquest by Qin

Archaeological evidence shows that several gallery roads from Qin to Shu were built during the Warring States Period over extremely difficult terrain, the Qinling Mountains and the Daba Mountains. Although legend attributes the building of the first gallery road, the ''Stone Cattle Road'' , to the last Kaiming king , the roads were probably built by Qin to prepare for its invasion of the Sichuan basin.

Qin took advantage of a dispute between the last Kaiming king and his brother, the Marquis of Zu, to invade Shu. The Marquis of Zu had allied with Ba in attacking Shu. In response, the Kaiming king invaded Zu and sent the Marquis of Zu into exile in Qin. The Marquis of Zu then appealed to King Huiwen of Qin to invade Shu.

At this critical juncture, King Huiwen's two primary advisors, and Sima Cuo, held opposing views on invading Shu. Zhang Yi believed that Qin was close to winning control over the Central Plain, arguing instead for an attack on Qin's traditional nemesis, . On the other hand, Sima Cuo argued that invading Shu would greatly increase the agricultural wealth of Qin, tipping the balance of power in Qin's favor. King Huiwen agreed with Sima Cuo and sent his two advisors to lead the invasion of Shu. Qin defeated Shu and killed the last Kaiming king.

Shu under Qin rule

Qin turned Shu into a commandery and applied a strict process for integrating Shu into Qin. Qin sent officials to rule directly in Shu and actively encouraged migration of people from Qin into Shu. Although Qin tried to placate the populace by retaining the Kaiming rulers as the Marquis of Shu, Shu would rebel many times against Qin; in turn, Qin would respond by reinvading or suppressing Shu.

When King Huiwen died in 311 BC, a Qin official in Shu, Chen Zhuang, led a rebellion against Qin. Sima Cuo, Zhang Yi and Gan Mao led Qin forces into Shu and suppressed the rebellion. In 301 BC, Marquis Hui of Shu, a Kaiming descendant, rebelled. Sima Cuo led Qin forces into Shu and suppressed the rebellion. Marquis Hui's replacement, Marquis Wan, also rebelled against Qin. This time, the Qin governor in Shu, Zhang Ruo, suppressed the rebellion. After the last rebellion, the Kaiming descendants were permanently removed from actual power.

After securing its control over Shu, Qin used Shu as a place of exile, a practice later followed by the Han Dynasty.


Nanzhong was an ancient region consisting of modern-day Yunnan, Guizhou, and southern Sichuan in southern China.

The region was the homeland of the rebellious Nanman tribes, led by Meng Huo. In 225 AD, the famed statesman Zhuge Liang led three columns into Yunnan to pacify the tribes. His seven captures of Meng Huo is much celebrated in Chinese folklore.

An anthology of lyric poetry known as the Amidst the Flowers Anthology was compiled in 940 It was also among the most stable of the southern kingdoms.

A new force arose in the north in 960 when the Song Dynasty replaced the Later Zhou Dynasty, the last of the . made it his mission to reunify the realm. forces forced Meng Chang to surrender in 965 on the road to the reunification of most of China.

Liu Xiang (warlord)

Liu Xiang or Liu Hsiang was one of the warlords controlling Sichuan province during the Warlord era of 20th century China.

During the period from 1927-1938, Sichuan was in the hands of five warlords: Liu Xiang, , Liu Wenhui, Deng Xihou, and Tian Songyao. No one warlord had enough power to take on all the others at once, so many small battles occurred, pitting one warlord against another. Large conflicts seldom developed, plotting and skirmishing characterized the Sichuanese political scene, and ephemeral coalitions and counter-coalitions emerged and vanished with equal rapidity.

However Liu Xiang was the most influential of the Sichuan warlords. He controlled Chongqing and its surrounding areas. This region, sitting on the banks of the Yangtze River, was rich because of trade with provinces down river and therefore controlled much of the economic activity in Sichuan.

From this position of strength, between 1930 and 1932 General Liu Wenhui and Liu Xiang improved their forces, organizing a small airforce at Chengdu, of two Fairchild KR-34CA aeroplanes and an unknown number of Junkers K53. In 1932 Liu began putting together the " and Tank Corps of Chungking". Armored cars were built in Shanghai based on the 1931 truck with a 37 mm gun and 2 MGs in a crude turret.

In 1935, Liu ousted his uncle and rival warlord, Liu Wenhui, becoming Chairman of the Government of Sichuan Province. A family-brokered peace was arranged which mollified Liu Wenhui with control of the neighbouring Xikang province, a sparsely populated but opium-rich territory on the periphery of Han China and Tibet.

At the beginning of the Second Sino-Japanese War Liu Xiang lead the Sichuan 15th Army at the Battle of Shanghai and 23rd Army Group in the Battle of Nanking, and was made Commander in Chief of the River Defence Forces for the Yangtze River. Liu Xiang died in 1938; some suspected he was poisoned by Chiang Kai-shek. Liu's death and the arrival of the central government in Chongqing in 1938 brought reforms that eventually put an end to the major warlord garrisons. The Sichuan faction broke up and a lot of Sichuan units turned their loyalties over to Chiang Kai-shek and became essentially Central army units.

Liu Wenhui

Liu Wenhui, or Liu Wen-hui was one of the warlords of Sichuan Province during China's Warlord era. Liu Wenhui who rose to prominence in Sichuan in the 1920s and 1930s, came from a peasant family. At the beginning of his career, he was aligned with the Guomindang, commanding the Sichuan-Xigang Defence Force from 1927 to 1929. The western part of Sichuan province was then known as Xikang. Bordering Tibet, the region had a mixed population of Tibetans and Han Chinese.


He was then made Chairman of the Government of Sichuan Province from 1929, but his relationship with Chiang Kai-Shek was unstable as was the province he governed. Sichuan was in the hands of Liu Wenhui and four other warlords: , , Deng Xihou, and Tian Songyao. No one warlord had enough power to take on all the others at once, so many small battles occurred, pitting one warlord against another. Large conflicts seldom developed, plotting and skirmishing characterized the Sichuanese political scene, and ephemeral coalitions and counter coalitions emerged and vanished with equal rapidity.

In May 1930 his province was invaded by the army of Tibet. With the province locked in internal struggles, no reinforcements were sent to support the Sichuan troops stationed in Xikang. As a result, the Tibetan army captured, without encountering much resistance, Garze and Xinlong . When a negotiated ceasefire failed, Tibet expanded the war attempting to capture parts of southern Qinghai province. In March 1932 their force invaded Qinghai but was defeated by the Qinghai warlord Ma Bufang in July, routing the Tibetan army and driving it back to Xikang. The Qinghai army captured counties that had fallen into the hands of the Tibetan army since 1919. The victory on the part of the Qinghai army threatened the supply lines to the Tibetan forces in Garze and Xinlong. As a result, this part of the Tibetan army was forced to withdraw. In 1932 Liu Wenhui in cooperation with the Qinghai army, sent out a brigade, to attack the Tibetan troops in Garze and Xinlong, eventually occupying them, Dege and other counties east of the Jinshajiang River.

In 1932 Liu Wenhui drove the Tibetans back to the Yangtze River and even threatened to attack Chamdo. At Batang Town, Kesang Tsering, a half-Tibetan, claiming to be acting on behalf of Chiang Kai-shek, managed to evict Liu Wen-hui's governor from the town with the support of some local tribes. A powerful "freebooter Lama" from the region gained support from the Tibetan forces and occupied Batang, but later had to withdraw. By August 1932 the Tibetan government had lost so much territory the Dalai Lama telegraphed the Government of India asking for diplomatic assistance. The Sichuan and Tibetan armies confronted each other across the Jinsha River until the Xikang-Tibet Gangto Ceasefire Agreement was made in June 15, 1933. By early 1934 a ceasefire and armistices had been arranged with both Liu Wen-hui and Governor Ma of Chinghai in which the Tibetans gave up all territory to the east of the Yangtze but kept control of the Yaklo district which had previously been a Chinese enclave to the west of the river.

Finally Liu Wenhui was ousted from Chengdu by a rival warlord, his nephew, Liu Xiang in 1935, when Liu Xiang sided with smaller warlords against Liu Wenhui. A family-brokered peace was arranged which mollified Liu Wenhui with control of the familiar neighbouring Xikang province, a sparsely populated but opium-rich territory on the periphery of Han China. Liu set up headquarters in the city of Ya'an and set about the highest priorities of a warlord: self-preservation and self-enrichment. Self-enrichment was relatively secure through the illicit but uncontrollable opium trade; survival entailed maintaining troops but using them as little as possible. In this, the territory of Xikang province was advantageous to Liu Wenhui, since its marginal position effectively insulated him from rival warlords, and from military engagements ordered by the central government.

During the GMD pursuit of the communist forces during the Long March, this conflict between the two leaders came to a head. Chiang repeatedly ordered Liu to bring his troops against the fleeing communists, but Liu made excuses, while secretly allowing safe passage for the Red Army in a non-aggression pact consistent with the first priority of a warlord: preserving one's troops and one's power. Thus the engagements around Xiakou in 1934 did not involve Liu Wenhui's 24th Route Army, but the 21st army of GMD troops garrisoned just across the Sichuan border in Mingshan.

From 1939 as Governor of Xikang Province Liu Wenhui tried to establish the infrastructure needed to support the remote province. Its transport was primitive and it had no industry to speak of. Large projects such as the hydroelectric plant built in 1944 promised to bring the area into the modern world. Liu Wenhui also promoted education as a way to improve Xikang’s situation.

Liu walked the tightrope of allegiance throughout the 1940's. He made sure that his forces saw as little action as possible, while at the same time he was careful not to arouse the full wrath of Chiang Kai-shek, and thereby continued to reap the benefits of wearing the Nationalist mantle.

As Governor of Xikang Province Liu switched sides from his half-hearted alignment with the Kuomingtang to siding with the Communists in 1949. He was rewarded with a bureaucratic post in the new communist government in Beijing. For the rest of his life, the former warlord served in various capacities in the Communist party, including as the minister of Forestry Ministry. Although Xikang ceased to exist in 1956 as part of the land reform, Liu Wenhui’s measures gave the area a solid basis for development. The hydroelectric plant he constructed in 1944 is still in operation. Kangding, once the provincial capital, is now a thriving town. In his last days, against governmental ban and relatives' objection, Liu Wenhui convinced his relatives to go to Tiananmen Square to pay his respect to Zhou Enlai when the Chinese premier passed away.

Li Bing

Li Bing was a administrator and engineer of the Warring States period. He served the as an administrator, and has become renowned for his association with the , the construction of which he is traditionally said to have instigated and overseen. Because of the importance of this 2000 years old system to the development of Sichuan and the Yangtze River region, Li Bing became a great Chinese cultural icon, hailed as a great civil administrator and expert. In Chinese mythology, he is known as the vanquisher of the and is compared to the Great Yu.

Life and career

King Zhaoxiang of Qin dispatched Li Bing as joint military and civilian governor over , a recently defeated state in Sichuan province, Southwest China, just of Chengdu. According to the ''Records of the Grand Historian'', Li Bing was appointed governor of Shu in c. 277 BCE. However, the ''Annals of the Huayang Kingdom'', written by the , place Li Bing in Shu in 272 BCE. He arrived just as Zhang Ruo had put down the last of the marquis rebellions and moved out to engage the Chu city of Yan. Conveniently, Zhang Ruo did not leave any incumbent ministers. Therefore, Li Bing had complete control over . “When he arrived in , Li Bing witnessed the sufferings of local people from frequent flooding of Minjiang River.” Additionally, the monarchy had been sending its exiles to this state and the military needed food and infrastructure.

Li Bing then created “the largest, most carefully planned public works project yet seen anywhere on the eastern half of the Eurasian continent.” It would be called , . He conducted an extensive hydraulic survey of the in order to stabilize the waters from flooding settlements and plot out an extension into Chengdu. This extension would be a fairway to provide logistical military support to the Chengdu supply lines. This is standard practice for administrators who routinely combine their agricultural projects for both the civilian and military purposes. The is 735km long and it is the largest and the longest of the Yangtze .

Li Bing faced a number of daunting tasks. Firstly, the administration was more experienced working with arid lands than with wet rice . Additionally, by slowing the water current, this reduced the river’s ability to carry away large sediments. At peak discharge, the flows at about 5000 or even 6000 cubic meters per second. At low water, it lessens to about 500 cubic meters per second. On the other hand, the water diversion would have a positive effect and with the system of land distribution with wet paddy rice in the Chengdu plains.

But that was only half of the problem. The other half had to do with culture. The native people of believed that the was a deity. As recorded in the , “ relates the tale that, upon appointment as administrator of Po, a province of , Hsi-men Pao discouraged the superstition of the people about a bride for the god of the river and punished the local gentry and bureaucrats who took advantage of such superstitions.” This was the ordinary practice of Administrators across the region. But, His-men Pao did not succeed. Therefore, in order to avert a similar massive revolt, Li Bing set out to end this practice “by a combination of tact and showmanship”.

Steven Sage describes from the that the first thing Li Bing did was setup a temple to honor the Min deity. He then offered his own two daughters as brides to the deity. But first he set up a large nuptial banquet along the river. He offered a toast. But the deity did not drink his glass of wine. Deeply offended, Li Bing runs off sword drawn. Two bulls prepared in advance were then seen by the crowd fighting along the river bank. Symbolically, this was Li Bing in a duel with the deity. Li Bing returns to the scene sweating as if in battle and calls for assistance. One of his lieutenants ran up to the bull that Li Bing had pointed out was the deity and killed the bull. The river spirit was subdued. “Through the medium of the bull, Li Bing had won.”

“In 268 BCE, Li Bing is said to have personally led tens of thousands of workers in the initial stage of construction on the Min River banks.” These people were mostly exiles from lands conquered by the , as well as pioneers, and the local population.

Later Shu

Later Shu was one of the Ten Kingdoms during the Five Dynasties and Ten Kingdoms Period in China from 907 to 960. It was located in present-day Sichuan with its capital in Chengdu.


The original Kingdom that was founded in 907 from the ashes of the Tang Dynasty was conquered by the Later Tang Dynasty, the second of the five dynasties that ruled the north during this period of time.

Meng Zhixiang commanded elements of the Later Tang Dynasty in the conquered territories of the Kingdom. He was named military governor in 925, but had plotted to make himself emperor, an action he took in 934 as, Li Siyuan, emperor of the Later Tang Dynasty, had seen relations with their powerful neighbors to the north, the , sour by his rule.

Territorial Extent

The Later Shu Kingdom held essentially the same territory as the Former Shu kingdom. The kingdom held most of present-day Sichuan, along with southern Gansu and Shaanxi, western Hebei and all of present-day Chongqing. As with the Former Shu, the capital of the kingdom was at Chengdu.


Meng Zhixiang died the year following his self-declaration of ascending to the position of emperor of the Shu. His son, Meng Chang ruled very ably for thirty years until the kingdom was incorporated into the expanding Song Dynasty from the north in 965.


Jiaozi (currency)

Jiaozi is a form of banknote which appeared in 10th century Sichuan. Most numismatists generally regard it as the first paper money in history, a development of the Chinese Song Dynasty .

Jiandi Dao

Jiandi Dao was a prefecture of ancient China located around today's Songpan region, in the east of Qingzang Plateau and northwest part of Sichuan province.

Jiandi Dao was originally founded by after it conquered in BC 316. Han Dynasty reestablished Jiandi Dao in the 6th year of Yuanding . Jiandi Dao was changed to Jiandi County and became a constitute part of Wenshan Jun in Jin Dynasty.

Di is an ancient large ethnic group lived in west China which is sometimes considered to be part of Qiang, called Diqiang. Dao in Qin and Han Dynasty is a kind of administrative unit where mainly settled by primitive tribes.

Campaign to the North of Nanchuan County

The Campaign to the North of Nanchuan County , Sichuan, was part of the Campaign in Southwestern China launched by the communists against the s in the region to the north of Nanchuan County during the Chinese Civil War in the post World War II era, and resulted in communist victory.

Order of battle

Defenders: order of battle:
*The XIV Corps
*The XV Corps
*The XX Corps
Attackers: communist order of battle:
*The III Corps of the Second under Chen Xilian and Zhang Linzhi
*The V Corps of the Second under Yang Yong and Su Zhenhua
*The 47th Army of the Fourth under Cao Lihuai and Zhou Chiping


The Campaign to the North of Nanchuan County begun on November 1, 1949 when the communists launched the Campaign in Southwestern China in multiple fronts against their adversary. By mid November, 1949, one of the communist attacks on the XIV Corps and XX Corps had succeeded in breaching the defense on both flanks, resulting in Youyang , Xiushan and Enshi falling into the enemy hands. By November 21, 1949, 4 s of the XIV Corps in the regions to the east of Salty Abundance in Hubei were completely annihilated by the enemy. The remaining s was forced to retreat westward by crossing the Black River . The communist III Corps and the 47th Army then turned their attention to the XV Corps and the XX Corps retreated to the region north of Nanchuan County by respectively crossing the Black River at regions including Gong’s Beaches , White Horse , Tukan , and north of Peng’s Waters . The major escape route to Qijiang in the west for the s were severed.

Chiang Kai-shek in Chongqing had realized the enemy’s intention of besieging Chengdu and Chongqing by striking behind the line from western Hunan and western Hubei via Sichuan and Guizhou, and thus immediately ordered Hu Zongnan to conclude Qinling Campaign by withdrawing from the defensive line, and enter Sichuan from and Greater Ba Mountain in order to avoid being isolated and surrounded by the enemy. The XV Corps and the XX Corps were redeployed to strengthen the defense of Nanchuan county and the region to its east in order to secure the retreat of Hu Zongnan’s troops. In order to counter the move, Liu Bocheng and Deng Xiaoping ordered the communist V Corps and the 10th Army to push toward Luzhou and Yibin from southwestern Guizhou, while the communist III Corps and the 47th Army to cross the Black River to push toward Nanchuan county and help other communist forces to besiege and annihilate the XV Corps and XX Corps. By October 28, 1949, the communist forces had fulfilled their tasks by badly mauling the two corpses in the region to the north of the county, thus successfully concluded the Campaign to the North of Nanchuan County.


This campaign of was a part of the Campaign in Southwestern China, and the s were defeated, losing over 60,000 in the process. The termination of the Qinling Campaign by withdrawing Hu Zongnan’s troops from defensive line meant that the s had lost a natural geographical barrier in the northern front, while the southeastern front was not improved either. As a result, the situation for the s further worsened in the Campaign in Southwestern China.

Battle of Jianmenguan

The Battle of Jianmen Pass was a battle fought between the and the during the Chinese Civil War in the post World War II era and resulted in communist victory. The battle was a one of the battles in Chengdu Campaign, which in turn, was part of Southwestern China Campaign.

Jianmen Pass was one of the most important gateways of Sichuan. There are 72 peaks in the mountain and the only road going thru the mountain was only 50 metre wide. Whoever controlled this 2 km long stretch of the road controlled the gateway of Sichuan, and the nationalists had built an elaborate systems of bunkers in the area to strengthen its defense against the inevitable communist assaults.

Order of battle
**A regiment of local garrison
**A company from the retreating 55th Division
**The 540th Regiment of the 180th Division of 60th Army of the XVIII Corps

After taking Guanyuan on December 14, 1949 in Chengdu Campaign, the communists correctly decided that Jianmen Pass must be taken. The 540th Regiment of the 180th Division of 60th Army of the communist XVIII Corps was tasked with this job and after three days of forced march of more than 40 km in the mountain, the communist 540th Regiment reached Jianmen Pass . The communist 540th Regiment immediately launched its assault on the pass by first completely annihilating a company from the retreating nationalist 55th Division tasked to strengthen the defense. Afterward, one of the battalion of the communist regiment was sent to outflank the defenders by passing the mountain terrain which was considered impossible by the local populace, including the defenders. The rest of two battalions of the communist regiment crawled forward along the ravine under the cover of darkness, and by 10:00 PM, they were within 50 metres in front of the pass. The attackers then launched their assault in the dark under the cover of heavy fire, and with the help of the battalion that outflanked the defenders, they were able to cross the last ravine via a log and overwhelmed the defenders. With Jianmen Pass falling into the enemy hands, the nationalists had no choice but to retreat and abandon the town of Jiange in the afternoon of December 18, 1949.

The communists managed to capture over 300 prisoners-of-wars and had the remaining killed in the fierce battle, and more importantly, the taking of Jianmen Pass secure the passage for the communists to attack deeper into the heart of Sichuan.

Bandun Man

The Bandun Man were an ancient people living along the Jialing River valley, in the area of modern Langzhong in Sichuan, China. Their name, literally meaning "board shield barbarians", is derived from their fighting style of charging with shields to break the enemy line. They were also called the Bohu Yi , meaning the "white tiger barbarians".

Ba (state)

Ba was an ancient state in eastern Sichuan, China. Its original capital was Zhi , Chongqing. Ba was conquered by in 316 BCE.

Ba, often described as a loose confederation or a collection of chiefdoms, consisted of several loosely-affiliated independent clans who recognised a king. The Ba clans were highly diverse, being composed of multiple ethnicities. Archaeological evidence shows that the Ba people relied primarily on fishing and hunting, with low levels of agriculture .

Ba may have aided the founders of the Zhou Dynasty in its overthrow of the Shang Dynasty at the Battle of Muye; however, Ba's first definitive appearance in recorded history occurred in 703 BCE; the Zuo Zhuan recorded that Ba took part in a joint military operation with Chu against Deng.

Ba territory originally included areas in the ; the ascendance of pushed Ba westwards and further into the Sichuan basin. Chu expansion forced Ba to move its capital several times. According to Chang Qu, capitals or administrative centers of Ba included Jiangzhou , Dianjiang , and Pingdu , with its final capital at Langzhong . During the Warring States Period, Qin, Chu and , all more powerful states, shared a common border with Ba.

Although Chu sometimes encroached on Ba territory, Ba shared a complex relationship with Chu, with strong trade and marriage ties. Chu also employed many Ba mercenaries as soldiers in its own army. This practice sometimes caused problems for Chu; in one instance, Ba mercenaries employed by Chu rebelled and besieged the Chu capital in 676 or 675 BCE.

Ba and Zu allied with Qin in Qin's invasion of Shu. After the successful invasion, Qin immediately conquered its two allies and captured the last Ba king. Ba was then converted into a Qin commandery. Unlike its management of Shu, Qin allowed the Ba elite to retain direct rule and did not force large -scale migrations of Qin people into Ba territory. The Ba elite would later be marginalized through a policy of divide and rule.

Ba culture

The tiger was an important part of Ba mythology, with the white tiger being held in highest esteem. Artifacts from Ba archaeological sites often employ tiger motifs. Other distinctive features of Ba culture include its distinctive curved blades, boat-shaped coffin burials and Ba-style bronze drums , which were used to communicate in battle.

Warfare played an important role in Ba society. The Ba people were famous for their war songs and dances. Their warriors were often employed as mercenaries by other states, and weapons were prevalent in Ba grave goods.

Ba and Shu developed their own writing systems, found on bronzeware. There are three scripts. One pictographic script was unique to Ba, and two scripts were found at Ba and Shu sites. All three scripts remain today.

2008 Panzhihua earthquake

The 2008 Panzhihua earthquake was a 6.1  earthquake that struck southern Sichuan province, China on August 30, 2008 at 16:30:50.5  . It was not an aftershock of the 2008 Sichuan earthquake. With more than 400 aftershocks, it has caused over 40 deaths, the collapse of 10,000 homes and damage to other infrastructure in the area. Maximum intensity of this earthquake was VIII .

Earthquake Details

According to the China Earthquake Administration and , a surface wave magnitude 6.1 earthquake struck southern Sichuan province, China on August 30, 2008 at 16:30:50.5 China Standard Time . The United States Geological Survey reported the same earthquake at moment magnitude 5.7.

The earthquake's epicenter was located at ,, in the Renhe District of Panzhihua, Sichuan, which is 50 km southeast of the city center. The epicenter is 60 km from Huili County in Liangshan Yi Autonomous Prefecture, Sichuan, 30 km from Yongren County and 55 km from Yuanmou County in neighboring Yunnan province.

The 2008 Panzhihua earthquake is also cited as the Renhe-Huili earthquake, especially in SCEA reports and early CEA reports.


A Ms 5.6 aftershock struck the same location on August 31, 2008 at 16:31:09.6 CST ,
causing at least two additional deaths.

By midnight September 1, there had been 439 aftershocks including the M5.6 one and two more exceeding M4.0.

Incidentally, a Ms 3.0 earthquake very close to the main quake's epicenter preceded the main quake by 2 hours 15 minutes.

Relation to Wenchuan Earthquake

Whereas the two and half months earlier in the same province even after August 30, the Panzhihua earthquake was not one of them because it was caused by a different fault line.

Response in China

Although the quake-stricken area is relatively low in population, reported at 118/km2,, early casualties and property damages were significant.
Within two hours, the CEA invoked its Level III emergency response protocol for disaster relief.

8,000 troops and para-militia were deployed to the disaster area.

Casualties, intensities, and damage areas

By September 5, authorities confirmed 41 deaths and 589 injuries. CEA also reported collapse of 10,000 homes, and damage to 190,000 more. Considerable damages to highways, bridges, and reservoirs were reported.

The map published by SCEA shows a maximum intensity of liedu VIII on China Seismic Intensity Scale , somewhat equivalent to VIII on from which CSIS drew reference.
The area affected by liedu VIII earthquakes covered a north-south oriented oval of 628 km2 centered around the epicenter, 39 km long and 19 km wide, including 28 km2 in Yunnan province. The total area of liedu VI and above is 9,634 km2, of which 6,265 km2 are in Sichuan.

1976 Songpan-Pingwu earthquake

The 1976 Songpan-Pingwu earthquake, magnitude 7.2, struck and in Sichuan, China on August 16, 1976. A M 6.7 and a M 7.2 aftershock earthquakes hit the same area on August 22 and 23. The earthquake struck with estimated population exposures of 1,500 at IX or greater and 5,700 at intensity VIII, resulting in 41 deaths.

1933 Diexi earthquake

The 1933 Diexi earthquake occurred in Diexi, Mao County, Sichuan, China on August 25, 1933.

This earthquake destroyed the town of Diexi and surrounding villages, and caused many landslides, and killed about 9,000 people. The old town of Diexi sank into the landslide dam-created Diexi Lake.
