3.113 Fall and Rise of China: Northern Expedition #4: Taking of Shanghai & Nanking

Age of Conquest: A Kings and Generals Podcast

Last time we spoke about the invasion of Zhejiang. Chiang Kai-Shek kept the momentum going by invading Zhejiang after taking Jiangxi and Fujian. However Sun Chuanfang in desperation ran to an unlikely ally, Zhang Zuolin to form the National Pacification Army. Now the NPA would go to war with the NRA. The NRA also faced internal strife as strikes broke out in Guangzhou and Wuhan. After quelling the worker strikes, the NRA began to concentrate on the Zhejiang campaign performing strategic counter attacks against Sun Chuanfangs offensives. By early 1927 Sun Chuanfang’s control over Zhejiang was being undermined by Zhejiang independence movement leaders who joined the KMT to overthrow him. Sun Chuanfang was served disastrous defeats, his armies began to rout with many plundering before they fled north. Those that still continued the fight fled for Shanghai, where Sun Chuanfang prepared to make a last stand to hold the NRA back before Zhejiang fell.

The NRA east route army had concentrated around Sungchiang just in front of Shanghai. They made it seem they were preparing for a major assault on the super city, yet up the Yangtze, half of the NRA were secretly preparing an offensive directed against Nanking. If the NRA captured Nanking and its strategic Tianjin-Pukou railway line, Sun Chuanfang’s forces south of the Yangtze would be isolated and cut off from reinforcements and supplies. On February 19th of 1927, Sun Chuanfang pulled his battered armies out of Zhejiang as he awaited reinforcements from Zhang Zongchang’s Shandong army.

Meanwhile the KMT called upon their agents and allies within Shanghai to foment disorder. Going back to November of 1926, KMT and CCP members within Shanghai had been assembling recruits together to strengthen their first united front. Shanghai held a large part of China’s modern factory workers, numbering in the several hundred of thousands. They represented a considerable percent of the Shanghai population. Following the formation of the NPA, Shanghai unions began attacking Sun Chuanfang for bringing Shandong mercenaries into Zhejiang and strongly disagreed with his alliance with the northerners. They had real grievances with the northerners, because they had ties to foreign powers like the Empire of Japan. Those in Shanghai sought to break the chains of foreign imperialism and wanted more autonomy. From 1926 onwards many unions, particularly those directed by the CCP organized demonstrations against Sun Chuanfang and the NPA.

By February of 1927 the anti-Sun Chuanfang movement really heated up. The National General Labor Union of the CCP had ordered some assassinations to terrorize the Chinese and foreign industrialists. To bring even more Shanghai workers under their influence and hurt Sun Chuanfangs hold over the city the CCP organized a political strike, similar to what had occurred in Hong Kong the year prior. A general strike in Shanghai was planned for February 19th and it would include the foreign concession factories. The strikers had 5 political and 12 economic demands. A major aim of the strike was to seize power through the use of the masses, even against a well armed regime like Sun Chuanfangs. The CCP hoped to direct large crowds of workers against Sun Chuanfang’s police stations and garrison posts where they could seize their weapons to arm some workers corps. They had acquired quite a bit of experience during the Hong Kong and Guangzhou strikers when it came to arming workers. However the response of Sun Chuanfangs regime would be vastly different than the KMT in Guangzhou.

Sun Chuanfangs garrison commander at Shanghai responded violently and quickly. He dispatched broadsword carrying executioners and soldiers through the city grabbing and beheading any strikers on sight. Heads were placed on lamp posts at street corners and on spikes all around. Its estimated out of perhaps 100,000 to 350,000 workers who striked, the headcount ranged between 100-500. The CCP continued its efforts to attack police stations, but the general strike died out on the third day. In a form of retaliation the Shanghai workers held a mass trial and execution of at least one police officer. A new garrison commander was sent to Sahnghai, Pi Shucheng in an effort to reinforce the city. By the point he showed up the CCP gave up and told the strikers to get back to work to end the bloodshed. What became known as the second shanghai uprising failed to achieve much.

Despite its failure, the second uprising in Shanghai displayed disunity under Sun Chuanfangs rule. By mid February Sun Chuanfangs Shanghai navy had begun to act suspiciously. On the 22nd as the CCP led sorties against the Shanghai Police, shells from the warships Chienkang and Chienwei fll over the Jiangnan arsenal. Thinking not much of it, Sun Chuanfang blamed a few young officers for the bombardment and gave his Admiral Yang Shuchuang a demerit. Sun Chuanfang was of course reluctant at this point to penalize his subordinates for fear they mutiny. The bombardment did not knock out the aresnal but a fire began mysteriously on the 28th blowing up 40 crates of artillery shells. The uprising did little to weaken Sun Chuanfangs hold over Shanghai, so the NRA shifted strategy. Over in Hangzhou, NRA units advance to the Sungchiang front while NRA units in Jiangxi advance downriver towards Nanking. The 6th and 7th NRA armies advance along the Jiangxi-Anhui border as the eastern route command dug in near Shanghai.

Back in December, at the Nanchang conference Chiang Kai-Shek and Borodin had managed to smooth the tension between the CCP and KMT. Borodin agreed to curtain some union disorder that were interfering with the war effort so the First United Front would not collapse. However within the new conquered territories, many that contained enormous industrial potential, strikes and labor violence kept breaking out. This was quite dangerous for the stability of the NRA as they performed the northern expedition. But from the CCP point of view they were simply organizing the enormous untapped power of Chinese workers. The CCP began to really grow in power at Wuhan and were becoming less cooperative with Chiang Kai-Shek. They believed Chiang Kai-Shek was dependent and at the mercy of Soviet aid. They also believed, since he had left Guangdong, a more malleable KMT military figure would better suit their interests. Thus a concerted effort was made to replace Chiang Kai-Shek.

You could call it a anti-Chiang movement sprang up and it was taking an effect on the Northern Expedition. Chiang Kai-Shek had just wired the Wuhan administration three times for funds to pay some disgruntled 7th army troops. The administration at Wuhan created by a joint council of the party and government, by insistence of Borodin, were generally compliant to Chiang Kai-Sheks demands. One of their leaders was Xu Chen, the current minister of justice. According to a group close to Wang Jingwei, it seemed the CCP, Chiang Kai-Sheks inner circle and the new Joint Council at Wuhan between January and February of 1927 were becoming quite dependent on Soviet advice. Early in January the CCP were attacking Chiang Kai-Shek with propaganda aimed to make it seem he was in bed with other warlords and the Japanese, thus a betrayer to Dr Sun Yat-Sens movement. Xu Chen the current commander of the 8th NRA army became a potential replacement for Chiang Kai-Shek, but the CCP were still afraid to risk open strife with the KMT. Borodin and CCP leaders like Mao Zedong were encouraged by the CCP membership growth in the countryside and within military units around Wuhan. As the NRA advance through Hunan, CCP membership increased as they spread through peasant associations. It was a similar case in Hubei. The Hunanese commander of the 2nd NRA army brought up the issue at a KMT meeting warning his colleagues “not to neglect the dangers of internal strife. Many of our members have become sidetracked by… ideas … not indicated in Sun Yat-sen’s instructions,… not belittle the enemy. Our enemies are now uniting together and gathering to attack us. We should concentrate the power of the Party and obey its orders strictly regardless of our own opinions.”

Chiang Kai-Shek of course was not oblivious to the danger all around him. He launched his own sort of counterattack. He began claiming the CCP strategy and those who were following them, threatened the all-class union of the KMT. On February 19th he urged a KMT audience during a speech to “look to … the doctrines of Sun Yat-sen and nothing else.” The anti Chiang Kai-Shek sentiment was felt in crowds at Wuhan. On February 24th, a crowd of 50,000 assembled at the party HQ parade ground where they made fiery speeches against Chiang Kai-Shek and against the Northern Expedition. “All we have seen is military power, but no Party power; individual will but not Party will…. Old degenerate counterrevolutionaries have caused these pathetic facts of the Party. That is why we must… knock down the feudal influences.” After this several people began chanting “Down with the Old and Degenerate!” Then another man made a speech stating “a few individuals could not do the work…. Now the old, rotten feudal thinking members manipulate the KMT, we must therefore knock them down.” Then the chant turned to “Down with Chang Ching-chiang,Oppose the Military Dictatorship.” Then the head of the NRA’s Political Departments, Teng Yenta stated “democratic centralization was the way to achieve the ideals of the Three People’s Principles, but now our leadership has been occupied by the old, ignorant, and the incompetent …, and we must overthrow personal dictatorship … and bring the military under control….”

Chiang Kai-Shek was enraged by all of this of course and he refuted the charges made against him. He singled out Xu Chen who had just made himself chairman of the new Joint Council without KMT party authorization. Chiang Kai-Shek began a little investigation and concluded it was Borodin’s doing so he telegrammed Moscow on February 26th requesting Borodin be sent back to the USSR. The next day at a KMT meeting, Chiang Kai-Shek told his colleagues he felt despite the fact the NRA advanced into new territories, while the people saw them as KMT members, they only heard propaganda from the CCP. By March the anti-Chiang cabal now sought to replace him with General Tang Shengchih, the Hunanese defector made commander of the 8th NRA army. According to one soviet report written on the 5th of March, Tang Shengchih was seen to be much more dependent on Soviet aid and a lot more cooperative in helping the anti-chiang effort amongst the other generals. A new anti-chiang alliance would require the support of other high ranking generals such as Chang Fakuai new corps, Chen Mingshu’s 11th army, Chu Peitehs 3rd army and the 9th and 10th armies. According to the same Soviet report, Tang Shenchih managed to turn Li Tsungjen against Chiang Kai-Shek and this hampered Chiang Kai-Sheks ability to obtain funds from Wuhan to pay Li Tsunjens 7th army.

Spring of 1927 brought more disunity to the First United Front and thus hurt the Northern Expedition. Although the NRA were clearly on a roll in Zhejiang and Fujian, their progress north of Wuhan and downriver from Jiangxi lost steam. Chiang Kai-Shek still held confidence of the men in the eastern route army concentrating along the Jiangsu-Anhui border, but their offensive was also halted. In southern Honan where the NRA were facing the remnants of Wu Peifu’s army, winter's chill was beginning to slow down the expedition.

The offensive kicked back up with a bunch of defections amongst Sun Chuanfang’s forces in Anhui. Chen Tiaoyuan, Sun Chuanfangs commander in Chief for his Anhui forces, had became dissatisfied with him and how he was ruling the 5 province empire…which I guess is now more like 2. Chen Tiaoyuan was demoralized, who could blame him. Back on December 5th of 1926, Chen Tiaoyuan began secret negotiations by dispatching some of his subordinates such as Fan Shao-kai over to the KMT hoping to defect and gain a decent position. Simultaneously, Sun Chuanfang maintained hope of holding his frontline in Anhui by promoting subordinates. Sun Chuanfang appointed Chen Tiaoyuan to be the director of defenses over the province on December 21st. On February 20th of 1927, one of Chen Tiaoyuans divisions, led by Liu Paoti defected to the NRA when he was guarding a strategic pass known as the Chimen gateway. This was a 5000 foot high range leading into Anhui. Now the NRA held a mountain side door leading directly into Anhui. The mountain range in question also happened to be the last natural barrier that Sun Chuanfang’s troops were utilizing to defend the lower Yangtze area, including of course Shanghai. After that Chen Tiaoyuang tossed the towel to the inevitable and defected to the NRA.

Chen Tiaoyuan proved his defection by turning his defensive sector along the Yangtze over on March 2nd. He brought with him the mixed brigade of Wang Pu and elements of the Hunan Army led by Yue Kaixin. The NRA proceeded to advance over the Yellow Mountain and down it to seize Taiping in Anhui on march 3rd. Pretty much unopposed the NRA marched upon Nanking through Anhui taking several routes. By March 17th, the 17th Division of Cheng Chens 6th NRA Army had advanced 200 miles downstream using river steamboats and was only 70 miles away from Nanking. Over the north banks of the Yangtze the NRA formed a spearhead and thrusted it into the soft midsection of the north-south railway. By mid march the NRA captured Hofei in northern Anhui. At this point Sun Chuanfangs relationship with his navy was greatly waning and he was becoming more and more dependent on the Tsinpu railway as an escape option to head north rather than via the sea. Thus March of 1927 saw the NRA effectively begin trapping Sun Chuanfang into the Yangtze delta around Shanghai.

The NRA southern forces were now advancing out of Zhejiang into the delta region. One pincer was heading north along the shores of Lake Tai aiming for the Shanghai-Nanking railway at Changzhou. Meanwhile in Anhui the 6th army was attacking Wuhu on the 6th of March. Anti-foreign disorder broke out at Wuhu as NRA political agents raillied crowds of civilians and soldiers to mob the foreigners maritime customs office and clubhouse. This sent the foreigners to flee downriver to Shanghai by ship carrying more tales of anti-foreign abuse with them. The eastern route force facing Shanghai was met with heavy artillery bombardment as more and more NPA troops from Shandong arrived. Several NRA attacks north of Shanghai against railway links were made, threatening the city's defensive capabilities. By mid march many forces defending Shanghai began evacuating for Nanking.

On March 15th the eastern route army had its first major breakthrough over the hills that overlooked Lake Tai. NRA forces managed to outflank the enemy artillery placements and erected a real blockade by march 16th. Now a new NRA pincer moved west against Lishui, 40 miles from Nanking. Along the east shore of said lake, the NRA was effectively blocked by Shandong troops who held an advantage in heavy artillery. By mid march many Shandong reinforcements arrived at Changzhou along the Nanking-Shanghai railway, but were simply turned back to Nanking. Not a good look.

From Wuhu the NRA kept the advance towards Tangtu which was outflanked and captured on the 17th, while the east route force took up a position 50 miles from Nanking on some ridges where Sun Chuanfang had once headquartered. On the 18th, north of the Yangtze the 7th NRA army just captured Hofei and its railway link. The delta area’s defenses were falling apart everywhere one looked. The Dogmeat General took one look and ordered a general withdrawal of all the Shandong forces from the Shanghai area to some positions north of the Yangtze. With that Shanghai defenses fell apart. Over at the Sungchiang front the forces of Pi Shucheng retreated into the city towards the railway station, but did not high tail it to Nanking despite being ordered to do so. According to foreign and Chinese journalists, Pi Shucheng had been waiting for the opportune moment to defect to the NRA and had been secretly negotiating to turn Shanghai over. Thus it seemed the NRA had managed to capture the city without provoking the foreigners. On the 20th the NRA managed to flank the railroad artillery position still manned by some White Russian forces. They managed this through more defections, this time from Shanghai police. The Shanghai police controlled the waterways and aided the NRA in navigating them so they could advance more rapidly. Simultaneously Suzhou, Changzhou and Henglin were captured. Sun Chuanfang was receiving zero aid from the sea for over a week by this point as AdmiralYang Shuchuang had taken the fleet upriver to join the NRA’s river fleet. Of course Admiral Yang Shuchuangs defection had been in the works for well over a year, but his timing could not have been worse for Sun Chuanfang. On March 21st a bloodless seizure of Shanghai proceeded.

Now going back to our conversation about the anti-Chiang Kai-Shek movement, there had been a lot of development during this time period. In January of 1927, Wang Jingwei with his left wing allies, members of the CCP and Borodin had transferred the seat of the KMT government from Guangzhou to Wuhan. On March 1st the KMT government then reorganized the military commission and placed Chiang Kai-Shek under its jurisdiction with the secret intent to arrest him. As the NRA was about to storm Shanghai, a major opportunity presented itself to the CCP. Most of the Northern Chinese defenders still stuck in Shanghai were simply looking to surrender. Thus on March 21st, CCP leaders Zhou Enlai and Chen Duxiu launched an armed uprising. The CCP seized weapons, created a general strike and seized most of the city. This caused many of Sun Chuanfangs soldiers to flee to the railway station or coasts, looting as they did. Major battle took place between armed workers and soldiers, causing fires and damaged to heavily populated areas of the city. For example in the northern suburb of Zhapei, armed workers burnt down 3000 homes. By the night of the 22nd Bai Chongxi’s NRA troops were gradually occupying the city, however the general strike was disrupting their efforts. General Bai Chongxi’ ordered the CCP to call off the general strike on the 24th, but for over 4 days 322 Chinese were killed and over 2000 were wounded. As the NRA consolidated their authority over the city, their top spokesmen, Chiang Kai-SHek, Ho Yingqin and Bai Chongxi tried to alleviate the foreign community who were ridden with frightened refugees in the international settlement. The settlement was a literal warzone, fitted with barbed wire, gates, marines and soldiers behind sandbag trenches and such. Very real and many false stories were spread of anti-foreign atrocities. The NRA put out notices stating “The purpose of the military operations of the Northern Expedition is to establish a nation governed by the people and to get rid of the warlords. Our army occupied Hunan, Kiangsi, Hupeh, Fukien, Chekiang, Anhui, and other provinces and the unification of the entire nation will be accomplished soon. The Party Army’s success is the victory of the people…. In accordance with international morality we shall guard the lives and property of foreigners. We have occupied Shanghai by more than force. We request that consuls inform your nationals to carry on your activities as usual and order the marines not to misunderstand our motives and not to carry out means to obstruct our revolutionary cause’. And now we come to a large and confusing part of the story. At Nanking and Shanghai major events would unfold, seeing the end of the first United Front.

After a few days, anti-foreign actions would follow the capture of Nanking requiring more and more public assurances from the KMT. The last demoralized rear guard crossed the Yangtze to get to the safer northern bank. By doing this, now the NPA’s most southern position was the rail terminal at Pukou. The NRA vanguard entered Nanking on March 24th, with units of the 6th army and countless NPA Anhui defectors alongside them. Chiang Kai-Shek loyalists in the KMT then charged the head of the 6th NRA army’s political department, a CCP member named Lin Xuhan with masterminding attacks upon foreigners. These attacks provoked the foreign powers to then attack Chiang Kai-Shek, diverting his attention from the northern expedition and weakening his authority over the new Wuhan government. Elements of the 6th army had stirred up anti-foreign attitudes amongst their troops and civilians within Nanking. Yet the foreign community in the city would go on to say the attacks they witnessed were not made by civilian mobs. Whatever motivations, the situation that unfolded at Nanking signified a giant breach of soldier discipline. For Chiang Kai-Shek to have permitted such actions to take place was inconsistent with his strategy of avoiding any provocation upon the foreign powers. Yet over 25,000 Nanking refugees flooded over to Shanghai as 25,000 foreign marines and soldiers began defending the concessions, assuring the NRA they were ready for a fight.

Going back in time somewhat, the March 20th coup was something akin to a patient zero. Back on January 3rd of 1927 elements of the KMT at Wuhan had triggered mobs to attack the British concessions until they gave back authority at Hankou and Kiukiang to the Chinese. Yet the KMT had never given such orders to do so. It seemed the CCP were pushing these actions. Between March 7th to the 17th, the new Joint Council at Wuhan was openly being defiant towards Chiang Kai-Shek and they held their first plenary session to work against him. They met with KMT leftists and CCP members and agreed to appoint CCP members, Su Chaocheng and Tan Pingshan as ministers; promoted CCP peasant and labour groups and dispatched three representatives to the Third Communist International to discuss China’s role in the would be world revolution. It did not seem the CCP intended to keep their promise to the KMT about China not going communist.

All of this authority at Wuhan undermined Chiang Kai-Sheks authority and those loyal to him. They immediately voted to take direct control of military funds which had been previously handled by the minister of Finance, T.V Soong, obviously considered a loyal supporter to Chiang Kai-Shek. In order to gain more influence in the NRA, the Wuhan guys began creating a parallel military chain of command and recruited CCP members into major officer positions. They hoped such actions would see more military types defect over to their cause. Now by this point the NRA really had become a giant beast. When the northern expedition launched in July of 1926 the were 8 armies, by March of 1927 they were now 40. Wuhans fiscal and political control over said armies would clearly undermine and probably be capable of getting rid of Chiang Kai-Shek, so it was a no brainer to attempt seizing them for the CCP. The Wuhan cabal hoped to incorporate some of the new armies, made mostly of defectors, whose alliances were probably flimsy to be under their control. Chiang Kai-Shek tried to counter these attacks, but anything he did would be seen as censorship or anti-communist, thus shattering the first united front, from which he still depended….or did he?

Now technically the Wuhan Cabal was only able to do what they were doing because leading KMT figures were not present such as Chiang Kai-Shek and Wang Jingwei. Thus lesser members like Xu Chen and Teng Yenta were able to make some big decisions. Both men were CCP aligned and worked to abolish Chiang Kai-Sheks posts that he held such as ministry of the military which was replaced by the Wuhan Military council. The Wuhan cabal was able to reduce Chiang Kai-Sheks role as commander in chief and give various tasks to other military commanders. Likewise the military education programs at the KMT academics removed Chiang Kai-Sheks supervisory role, depriving him of obtaining the loyalty of the new junior officer corps. Appointment, promotions and dismissals of commanders would be done by the Military council, ie: Xu CHen and Teng Yenta. They first relieved Chen Mingshu, a known Chiang Kai-Shek loyalist and replaced him with a Moscow certified star Tang Shengchih. It became very obvious what they were trying to do.

Thus as the Wuhan cabal tore apart Chiang Kai-Sheks authority piece by piece, the NRA’s war against Wu Peifu and Sun Chuanfang began to collapse. Without a high degree of coordination and leadership, the NRA was finding it difficult to fight the numerically superior NPA forces. In March of 1927, Wuhan proclaimed all regulations ordered by Chiang Kai-Sheks HQ to be nullified. This meant although he retained authority over troops at the frontlines, Wuhan now claimed authority over all the other troops. All of these attacks upon Chiang Kai-Shek caused massive confusion in the ranks. Many within the KMT believed and rightfully so that the CCP was trying to take leadership over the movement. As the northern expedition took the NRA into Jiangsu, the momentum of their previous victories had pushed them across the Yangtze. This was heavily aided by the recent Shanghai Navy defectors who eased the crossing using their vessels. Those already operating north of the Yangtze such as the 3rd, 7th and 10th armies were pressing past Hofei towards Pengpu by early April. Pengpu was the capital of Anhui, forming a sort of bridgehead over the Huai river with a railway depot for Zhang Zongchang’s armies. Thus its capture would open a door to the invasion of North China. Yet the NRA’s momentum died in confusion over which direction they were to take, because of the Wuhan cabal-Chiang Kai-Shek fighting, and their logistical support was falling apart. It seemed to all like the northern expedition might never make it to the north.

The NRA managed to seize the super cities of Shanghai and Nanking. The NRA now dominated most of south China and were about to begin invading the north, when internal problems arose. The CCP and Chiang Kai-Shek were not seeing eye to eye and now a civil war seemed to be breaking out in the first united front.
