Before Ye Ting's return to the N4C army headquarters, Chen Yi, on June 15th, 1940, decided to concentrate his troops to the north of Yangtze for dealing a blow to Haan Deqing's government troops to the north of the Yangtze in lieu of attacking Leng Xin's 2nd Guerrilla District to the south of the Yangtze.
To lower the government troops' vigilance, Chen Yi ordered Su Yu, his newlywed young wife Zhang Xi and the communist troupe to go to Leng Xin's 2nd Guerrilla District command center for a condolence performance.
Meanwhile, the communist troops stealthily crossed the Yangtze for the north bank.
North of the Yangtze River, the communists in 1939 had successfully bought over commander Chen Yusheng, i.e., the 8th detachment commander serving under the 3rd 'zong dui' [corps] of Li Mingyang's North Jiangsu provincial guerrilla troops.
(Chen Yusheng's story was similar to Jiang Shangqing, i.e., uncle of communist secretary Jiang Zemin [whose birth-father was a deputy in the puppet Whang Jing-wei government's cultural ministry]. The difference between Chen and Jiang was that Jiang Shangqing was killed in an in-fighting among the guerrilla factions while prematurely attempting to hijack the guerrilla army to the communist side at the Jiangsu-Anhui border, while Chen Yusheng was able to connect with the communists at a mature time.
Chen Yusheng was the father of Chen Huimin [Chen Luwen], a sexy girl who became Mao Tse-tung's sexual stunner since age 14 in 1962, a woman who aspired to be known as the tyrant's woman the same as the pair of Tang Emperor Ming-huang and Concubine Yang-gui-fei.)
After solidifying the Mt Maoshan base, Chen Yi crossed the Yangtze for Ye Fei's beachhead strongholds on the night of June 28th, 1940.
The communist forces, in observance of Liu Shaoqi's order of replaying the Bantaji trick, had taken over Guocun (Guo village) on May 17th and drove a wedge into provincial guerrilla army commander Li Mingyang and Li Changjiang's territories.
With Chen Yusheng stealthily assisting the communists, the N4C army established beachhead and penetrated northward.
On July 14th, Chen Yi, in observance with Liu Shaoqi's "advance east, advance east, and further advance east" slogan, reported to the N4C headquarters and the CCP Central about the pending military action against the Jiangsu Provincial 4th Constabulary Brigade at the Huangqiao [yellow bridge] Town.
On the pretext that Haan Deqing had convened a meeting at Dongtai in regards to forbidding the rice flow to the south from the Haian-Taizhou line, Liu Shaoqi authorized a once-for-all solution to the Northern Jiangsu issues with a promise of nine strike battalions attacking south from behind Haan Deqing's Xinghua-Dongtai rears.
On September 12th, Chen Yi ordered a siege campaign against the electricity-wired Jiangnian stronghold.
Haan Deqing, having devised a fake attack plan against Jiangnian, dispatched Li Shouwei's 89th Corps and Weng Da's 6th Independent Brigade against Huangqiao from the Qutang-Haian direction. With advance information of Haan Deqing's three-route attack plan, the communist forces concentrated on fighting against the National Army 89th Corps and the 6th Independent Brigade.
On October 4th, the 6th Independent Brigade, coming towards the north of Huangqiao from the Guxi direction, was ambushed, intercepted and encircled by the N4C 2nd Column and 1st Column along the two sides of the Guxi-Huangqiao Highway.
Brigade commander Weng Da committed suicide.
The N4C 2nd Column and 1st Column, after routing Weng Da's Brigade, circumvented to the hind of the National Army 33rd Division and 117th Division at midnight. On October 5th, the communist forces launched a three-direction general attack.
On the rooftops, the communist forces, including one battalion from the Old 4th Regiment that just crossed the Yangtze, claimed to have engaged in 8-9 bayonet battles, and after piercing dead 1000 government troops, drove back the 33rd Division. By midnight, the communist 2nd Column and 3rd Column routed the National Army 33rd Division.
Under the joint attacks by the communist 1st Column and 2nd Column, Corps Chief Li Shouwei ordered a general pullback. At the Bachihe River, Li Shouwei got drowned after losing hold of the horse tail, with his body identified by wife Ma Bangzhen [using an odd button that was knit on the clothes prior to the campaign] among thousands of corpse that were retrieved by fishing nets months later
At least 5000 government troops lost their lives during the Huangqiao-Xinghua Battle.
Though, the Comintern and I.P.R agents, embedded with the communist N4C since 1938, continued to broadcast the fake news of the communist N4C fighting against the Japanese through relay of the news agencies in Shanghai's international settlement.
