During the confrontation between the main force of the Ming army and the Qing army in Xiangtun Qi on the Hunan battlefield, Sun Kewang sent another troops to attack southern Sichuan with the intention of occupying all Sichuan. At the same time, the Qing court also sent King Pingxi Wu Sangui and General Gushan Ezhen Li Guohan to lead his troops from Hanzhong, Shaanxi to Sichuan. Wu Sangui and Li Guohan led his troops to enter Sichuan from Hanzhong, Shaanxi. After resting for a few days, they went south and quickly advanced to Chengdu. Lin Shitai, the general of the Ming army guarding Chengdu under Sun Kewang's order, faced the Qing army who came from afar but surrendered without fighting, resulting in the Qing army not losing one soldier and one soldier to occupy Chengdu.

Lin Shitai joined the Daxi Army led by Zhang Xianzhong in his early years. After Zhang Xianzhong died in battle, Lin Shitai felt that the Daxi Army had no future, so he surrendered to Prince Ying of Qing, Ajige, who appointed him as the general of Baoning. A few years later, Lin Shitai heard that the remaining troops of the Daxi Army united to fight against the Qing Dynasty under the leadership of Sun Kewang and Li Dingguo, and then opposed the Qing Dynasty in Tongchuan. Sun Kewangnian ordered him to lead his troops to station in Chengdu in the past.

After Lin Shitai surrendered to the Qing Dynasty again, Wu Sangui believed that this person was capricious. When he returned to the Ming Dynasty, the Qing court issued a Ming order to arrest him, so he ordered Lin Shitai to be beheaded and displayed in public. All 1,650 of his confidants were killed.

After the Qing army occupied Chengdu, Wu Sangui was in charge of the city, and Li Guohan led the troops in Meizhou and Jiading, and captured the former local officials of the Xuanwei Office of Shipingzhou, Lin'an Prefecture, Yunnan Province, and Long Mingyang, who is now the general of the Ming Dynasty. Later, Wu Sangui and Li Guohan mobilized Meilezhangjing Ge Chaozhong, Bai Hanzhen, Tong Shisheng, Kuizhou general Lu Guangzu, left general Chen De, Yongning general Bai Yongfu and others to attack Chongqing. On the fifth day of the lunar month, they occupied Hezhou and advanced to Chongqing in two routes.

Lu Mingchen, the commander of the Ming army in Chongqing, was unable to resist the fierce Qing army, so he gave up Chongqing on the 14th. In late April, Wu Sangui sent another Qing army led by Jialazhangjing Yang Zhengtai, Guo Yunlong, the right-hand general Nan Yikui, and the general of Xuzhou Ma Huabao, to attack Xuzhou. The commander of the Ming army, Wang Fuchen, and Bai Wenxuan, knew that they were defeated and voluntarily retreated to Yongning. At this point, in addition to the Baoning area that was originally controlled, the Qing army successively captured Chengdu, Chongqing, Xuzhou, Mahu, Qiongzhou, Yazhou, Jiading, Meizhou and other prefectures, and most of Sichuan were in the hands of the Qing army. As a result, the Qing court believed that the entire Shu was gradually settled and should pay attention to the aftermath of the Tianfu. With Sichuan's material resources to support its subsequent offensive against Yunnan and Guizhou.

Sun Kewang, who was confronting the Qing army in the Hunan battlefield, learned that Sichuan was unstable and that the Qing army had occupied most of Sichuan. He was afraid that the Qing army would gain a foothold in Sichuan and then invade Guizhou in the south, so he sent Funan King Liu Wenxiu to lead 40,000 to 50,000 reinforcements into Sichuan in three directions, and from Jianchang, Xuyong and Pengshui launched a full-scale counterattack. On the ninth day of August, the Ming army captured the Xu Prefecture, and the Qing soldiers guarding the city were wiped out. The general Nan Yikui was unknown. The general Ma Huabao fled back alone. More than a dozen people died in Jiala and Niulu. At the same time, Sun Kewang's general Bai Wenxuan also led his troops to counterattack Chongqing from Yongning.

Seeing that the Ming army was in great power, Wu Sangui and Li Guohan urgently discussed with Sichuan Governor Li Guoying in Jiajiang County on August 19, and decided to withdraw the entire division north to protect Wanquan. The Qing army generals stationed in Chongqing, Meilezhangjing Ge Chaozhong, Tong Shisheng, Bai Hanzhen, Zhang Jingyin Decai, the generals Bai Yongfu, Chen De, and Lu Guangzu received the retreat order from Wu Sangui on August 24, and crossed the river north to return on the 25th. On the same day, the Ming army recovered Chongqing and immediately sent troops to chase the Qing army. They surrounded the Qing army in Tingxi, 120 miles away from Chongqing, and besieged the Qing army with firearms. On the 28th, the Qing army was defeated. Meilezhangjing Bai Hanzhen was captured alive. When Yongning general Bai Yongfu fled to Baoning with the remaining defeated soldiers, his subordinates were separated and weakened. Only more than a hundred remaining soldiers were collected.

In September, Wu Sangui also led his troops to retreat to Mianzhou, and then to Guangyuan. As a result, the Qing Dynasty's temporary provincial capital in Sichuan, only the inspector's censor Hao Yu and General Yan Ziming, had more than 100 soldiers under the command of the army. Wu Sangui and Li Guohan had already given up on Sichuan's plans to retreat to Hanzhong, Shaanxi under the situation of defeat.

Governor Hao Yu persuaded Wu Sangui with the words "If you don't die from the thief, you will die from the law." Li Guohan should not abandon Baoning. Sichuan Governor Li Guoying also grabbed Wu Sangui and persuaded him hard: "The king is a guest soldier and can return to the Han Dynasty; the governor is a minister who guards the territory. He should live and die with Baoning. The king has returned to the Han Dynasty, and the governor returns to Baoping at night to prepare food." After saying that, he said goodbye to Wu Sangui and Li Guohan. He led hundreds of battalions of troops to set up the camp and return to Baoning.

Seeing this, Li Guohan hesitated and said to Wu Sangui: "We commanded the army, Huichuan, cannot be allowed. If we abandon Baoning and lose the governor, our court will know that the king of law will do anything to the court again?"

After hearing this, Wu Sangui woke up. The flying envoy recovered Li Guoying and asked him, "I want to go to guard Baoning. Does the governor have food?"

Li Guoying said: "Although Baoning doesn't have much grain, it's enough for soldiers and horses to spend five months."

Seeing that Baoning had food to support, and was afraid of losing the land and losing the governor, Wu Sanguina led his troops to return to Baoning with Li Guohan.

After Liu Wenxiu conquered Xuzhou and defeated the Qing Dynasty's defenders, he was invincible along the way, which led to arrogance of the enemy. After his troops arrived at the outskirts of Baoning City, Liu Wenxiu decided to forcibly attack the city without sufficient confidence. Wu Sangui and others saw that there was no way out, and only if the trapped beasts still fought and the battle behind the city could survive.

On the eighth day of October, the main forces of the Ming army gathered in the north of Baoning City, and Liu Wenxiu climbed to the northeast mountain to command the siege. Wu Sangui learned through reconnaissance that Zhang Xianbi's troops had the weakest combat effectiveness in the Ming army, so he decided to concentrate their troops to attack Zhang's army first. In order to confuse the Ming army, Li Guoying ordered his subordinates to change to attack the Eight Banners's Soldiers.

At dawn on October 11, Liu Wenxiu commanded a large army to attack the city, and the troops covered the mountain and the sound of cannons shook the sky. From the river bank in the south to Shagouzi in the north, it lined up for fifteen miles. The forefront war elephants were used, and then they used cannons, bird guns, cards, flat knives, bows and arrows, and spears, and they flocked to attack the city.

During the Chen period, Wu Sangui led his troops to open the gate and attack Zhang Xianbi's army directly. Zhang's army could not resist the enemy and fled one after another. The defeated troops rushed into chaos with the army of Wang Fuchen and others. The Qing army took advantage of the situation to fight bravely. The Ming army's formation was in chaos and could not stand on its feet. It collapsed completely at noon that day. During the retreat, a large number of soldiers could not cross the river, and were chased by the Qing army or died by the Qing army. The Ming general Wang Fuchen, general Yao Zhizhen, Zhang Xianzhen, Wang Jiye, Yang Chunpu and others were successively captured and killed by the Qing army, losing most of the soldiers, three battle elephants, more than 2,300 horses and mules, and Liu Wenxiu's golden seal of Funan King was also seized by the Qing army.

After winning the victory, Wu Sangui sighed to his left and right: "I have never seen such a strong enemy in my life, so I have no choice but to hear it."

Liu Wenxiu led the defeated soldiers back to Guizhou. Sun Kewang was deeply dissatisfied and ordered his military power to be lifted and sent back to Kunming to live; Zhang Xianbi was beaten to death by sticks.

During the Security Battle, because neither side could afford to eat each other, the Ming and Qing dynasties were in a stalemate on the battlefield in Hunan for a long time. During this period, Sun Kewang led his troops to firmly guard the front lines of Chenzhou, Yuanzhou, and Wugang, and the Qing army guarded the Changde, Changsha and Baoqing areas. In the ninth year of Shunzhi, Tunqi led the remaining troops of the Eight Banners of Manzhou brought to Hunan by Nikan to Beijing for rest. This move made Hong Chengchou, the newly appointed governor of the five provinces, complained and reported several times to the Qing court with concern, asking the Qing court to increase his troops, otherwise the situation in Huguang would not change.

Hong Chengchou complained that there were reasons. Shunzhi used him to implement the strategy of "using Han to control Han" set by Dorgon at that time to avoid excessive losses in the southern battlefield of the Eight Banners of Manzhou. Therefore, as soon as Hong Chengchou arrived in Wuchang, Shunzhi urgently ordered all the Eight Banners of Manzhou in Hunan to withdraw from Beijing by Tunqi. The war in Huguang was entirely responsible for the Han army flag and the Green Camp. However, Hong Chengchou designated that only more than 10,000 troops were mobilized to Hunan, and the former stationed in Huguang and Guangxi.

The Green Camp soldiers in Sichuan were definitely not comparable to the Southern Ming army commanded by Sun Kewang, Li Dingguo and others, and the actual number of soldiers was less than 20,000. As soon as the backbone of the Manzhou soldiers retreated, the Han army and the Green Camp were even more frightened. Facing the tens of thousands of Southern Ming army commanded by Sun Kewang in front of him, they were all afraid and dared not provoke easily. If Sun Kewang had not been able to launch an offensive in Hunan at this time, Hunan would probably have fallen into the hands of the Ming army because of the withdrawal of the Manzhou soldiers of the garrison Qi.

Hong Chengchou knew that relying solely on his troops to deal with the Xiangxi, which was directly commanded by Sun Kewang, the Ming army in Guizhou and the thirteen armies of Kuidong were not only unable to defeat the enemy and win, but even defended the Yiling, Jingzhou, Changde, Changsha, and Baoqing in Hubei. As for most of the Guangxi areas within his jurisdiction, he was still controlled by the Southern Ming general Li Dingguo, he was even more unable to do so.

Furthermore, after a long war in Hunan, the place was destroyed. The so-called great enemies were in front of the country and small enemies were in the wild. The troops were everywhere, and the trouble of sending them to welcome them. The people were attracted by one or two refugees and fled again. The people did not come, and some officials wanted to leave. The city of Changsha, where Hong Chengchou was stationed in the Jie Dynasty, was extremely depressed. There were no people or houses outside the city of Baoqing City, and there was no vegetable trading.

Faced with such a mess, Hong Chengchou worked hard to organize the Green Camp and other Han soldiers to defend the local area, and asked the court to send another Manchu army to assist in the war. He urged the Qing court to order King Geng Jimao of Jingnan to quickly move to Wuzhou, Guangxi. The actual intention was to push the responsibility of capturing Guangxi and restraining Li Ding's Ministry of the Ming army to the two Han vassal kings in Guangdong.

After receiving Hong Chengchou's memorial, the Qing court did not issue an order to allow King Geng Jimao of Jingnan to move to Guangxi, but he also knew that the Han soldiers and horses controlled by Hong Chengchou alone could not compete with the Ming army. So in December of the tenth year of Shunzhi, Shunzhi appointed Chen Tai, Gushan's Ezhen General, Ningnan Jing's Great General, Gushan's Ezhen Lan, and Jixiha and others led the Eight Banners troops to Hubei and Hunan to guard. Chen Tai was appointed as the General, Ningnan Jing's Great General, Ningnan Jing's Great Army, but did not lead the troops south, but waited until the Tunqi troops returned to Beijing before heading south. More than a year passed.

In April of the 12th year of Shunzhi, the troops sent by Chen Tai, the Eight Banners soldiers Gushan Ezhenji Xiha and Lan Bai, entered Hunan. The troops led by him arrived in Jianli County, Hubei Province due to the flooding of rivers and the river embankment, and could not advance until they died of illness and failed to reach Hunan.

After the Eight Banners soldiers led by Ezhenji Xiha and Lan Bai arrived in Hunan, Sun Kewang knew that killing the generals and snatching the flag was not his chief, so he decided to re-appoint the Funan King Liu Wenxiu, who was stripped of military power due to the Baoning Battle. However, Liu Wenxiu became increasingly negative since Baoning was defeated and deprived of military power. When he was deposed in Kunming, he even wanted to go to the mountains to learn Taoism. Sun Kewang summoned him several times to Hunan. Finally, under Sun Kewang's insistence, Liu Wenxiu took up the position of "Dada Tactics". In the spring of the ninth year of Yongli (the 12th year of Shunzhi on the pseudo-Shunzhi), Liu Wenxiu led the generals Lu Mingchen, Feng Shuangli and other troops, with 60,000 infantry soldiers, and more than 40 elephants, and embarked on the journey to attack Huguang in the east. In April, Liu Wenxiu's troops gathered in Chenzhou, Hunan, and planned to first capture Changde, cut off the passage to Hubei and Hunan to the west of Dongting Lake, and then recover Changsha, Hengyang, and Yuezhou. After succeeding, he attacked Wuchang in the north.

According to Liu Wenxiu's deployment, the Ming army attacked Changde and adopted the policy of advancing water and land. Liu Wenxiu sent Lu Mingchen to lead an army to advance from the Yuan River by boat, and he led his army to advance from land. When the Ming army set off, it was the rising season. Lu Mingchen's troops took more than 100 ships down the river. On April 17, it captured Taoyuan County and captured Li Ying, the magistrate of the Qing Dynasty. However, the main force led by Liu Wenxiu himself had rained for days, the streams soared and the roads were muddy, and it was very difficult to move. The horses and infantry were stranded for dozens of days and could not cooperate with the water and roads controlled by Lu Mingchen.

After receiving the news that Liu Wenxiu's army entered Hunan, Hong Chengchou and Chen Tai quickly took countermeasures. In addition to drawing troops from Hengzhou and other places to defend Changsha, the provincial capital, on the 10th of May, they dispatched the Eight Banners of Jingzhou to Changde to strengthen their defense. On the night of May 23, Lu Mingchen's troops advanced to Changde and were ambushed by the superior Qing army. Because they could not get support from the Ming army by land, the fierce battle lasted until the next day, Lu Mingchen fell into the water and died for his country, and the Ming army by water was almost wiped out.

After the war, the Qing army strengthened its defense in Chenzhou. The plan of Liu Wenxiu and Lu to attack was declared unsuccessful. Lu Mingchen's death seriously affected the morale of the army. Liu Wenxiu had to give up the plan to capture Changde and lead the army back to Guizhou. Sun Kewang expressed deep dissatisfaction with Liu Wenxiu's actions, and once again lifted his military power and allowed him to return to Kunming, Yunnan to live in leisure.

Sun Kewang appointed Liu Wenxiu as the ultimate move, with the original intention of letting him lead his army from Xiang to the Yangtze River in the eighth year of Yongli to join forces with Zhang Mingzhen and others to seize Jiangnan. At that time, the Qing army of Tunqi retreated north, and Chen Tai's Qing army had not yet advanced south. It was a great opportunity to defeat the Han army pieced together by the Qing ruler Hong Chengchou in one fell swoop and advance to Jiangnan. However, due to Sun Kewang's plan to usurp the throne and wanted to take over the Ming Dynasty. Liu Wenxiu, who had always opposed this move, was unwilling to act according to Sun Kewang's strategy, so as not to successfully usurp the throne. As a result, his unmoved army led to the complete plan of Sun Kewang's intention to meet with Zhang Mingzhen in the east and west and join Jiangnan.

After the Battle of Changde, Liu Wenxiu returned without success, and Chen Tai died of illness. Although the Ming army was defeated in the Battle of Changde, the Qing army did not obtain any territory in the Southern Ming Dynasty, and basically confronted the Ming army in western Hunan.
