In the fifth year of Yongli, Sun Kewang completed the annexation of the warlords in Guizhou. Guizhou was connected to the four provinces of Sichuan, Huguang, Yunnan and Guangxi, and on the one hand, the army was led by Feng Shuangli to capture Yuanzhou and enter Huguang with one foot, while on the other hand, Liu Wenxiu, the king of Funan, another of the three kings such as Sun Kewang and Li Dingguo, entered Sichuan and annexed the local warlord armies to complete the integration of the Ming armies in the southwest.

The Ming army entered Sichuan, and due to the feud between the Great Western Army and the Sichuan Army, a large number of Sichuan army generals switched to the Qing court. At the same time, threatened by the Ming army's entry into Sichuan, the Qing court sent Wu Sangui, the king of Pingxi, and Li Guohan, the guard of the Han army with the blue banner Gushan Ezhen Morgen, to lead the former Guanning army, the Han army banner that assisted in the defense of Shaanxi, and the Shaanxi green camp to move south, and captured the provincial capital Chengdu on February 22, the sixth year of Yongli. However, Lin Shitai, the defender of the Ming army who surrendered without a fight, was beheaded by Wu Sangui because he had surrendered to the Qing army earlier.

In the next few months, Wu Sangui and Li Guohan mobilized Mei Lezhang, Jingge Chaozhong, Bai Hanzhen, Tong Shisheng, Lu Guangzu, Kuizhou General Soldier, Chen De, Left Road General Soldier, Yongning General Bai Yongfu and other Qing army generals took the lead and captured a large number of prefectures and counties such as Meizhou, Jiading Prefecture, Hezhou, Chongqing, and Xuzhou, basically completing the strategic goal of "gradually determining the whole of Shu".

The threat of the Qing army approached from the north, and just when Li Dingguo won a great victory in Guilin and then recovered the entire territory of Guangxi, Sun Kewang sent Liu Wenxiu to lead 40,000 southwestern Ming troops to enter Sichuan again, and launched a comprehensive counteroffensive from Jianchang, Xuyong, and Pengshui.

On the ninth day of August, the Ming army conquered Syria, and the Qing soldiers who were defending the city "were wiped out, and the southern general soldiers did not know their whereabouts, and the general soldiers of Ma fled back alone, and more than dozens of victims died in Jiala and Niulu" (Note 1), which was a great victory for Xuzhou.

At the same time, Liu Wenxiu's deputy general Bai Wenxuan led the army to attack Chongqing, Sichuan governor Li Guoying and his generals fled without a fight, but they were caught up by the Ming army at Zhuxi one hundred and twenty miles away from Chongqing, the Qing army was defeated, Meile Zhangjing Bai Hanzhen was captured alive, and when Bai Yongfu, the general soldier of Yongning, fled to Baoning with the remnants of the defeated soldiers, his subordinates "were weakened and weakened, and only a hundred people were obtained". When Wu Sangui, Li Guohan and others led the main force of the Qing army to flee north, they were also pursued by the Ming army, and the losses were quite huge.

In a short period of one month, the Qing army suffered heavy defeats one after another, and had to give up the entire territory of Sichuan except for Baoningfu, an important town in northern Sichuan, which was the gateway to southern Shaanxi, and surrendered the entire Sichuan that had been captured for less than half a year to the Ming army. At this time, while Liu Wenxiu was collecting the whole of Sichuan on the side, the army was also continuing to move north, and the troops were directly aimed at Baoning and Shaanxi behind Baoning......

The war situation in Sichuan deteriorated, and the Eight Banners Army under the command of Arzin and Ma Laxi, which had been promised by the Qing court, was forced to divert to Shaanxi to defend Hanzhong, thinking that Wu Sangui, Li Guohan and Li Guoying were the backing of Wu Sangui, Li Guohan and Li Guoying.

The Qing court issued an order to Shang Kexi and Geng Jimao to inform them of the situation, but at the same time, the Qing court also sent the Eight Banners Army, led by Gushan Ezhen Zhuoluo as the general of Jingnan and the generals of Gushan Ezhen Lanbai and other generals, to replace the Arzin Department to assist the two feudatories in capturing Weidingzhou County in Guangdong.

There is a distinction between priority and priority, which is understandable, anyway, it is all the Eight Banners Army. However, Arzin, who had already reached the halfway point, turned to the northwest, and Zhuo Luo set off from Beijing again, which meant that the time for the Eighth Banner Army to arrive in Guangdong would be further delayed.

Waiting is inevitable, and Shang Kexi and Geng Jimao are also more inclined to dogs and people. However, it didn't take long for the Qing court to see that the remnants of the Dingnan Domain were sweeping through Guangxi with the support of Shang Geng's second domain, and then the money and food were insufficient, so they directly let Zhuo Luo's troops return to Beijing. In Guangdong, it is still the affairs of the Shang Geng Clan to be responsible for the conquest and suppression. (Note 2)

This year, the Qing army in the southwest and southeast is tight, the southwest and southeast Ming army in the Sichuan, Huguang and Guangxi battlefields of the big counteroffensive, the southeast Ming army Zheng Chenggong also launched a large-scale attack on southern Fujian, plus Chen Kai has to jump out from time to time to add a little disgust to the Qing army. For this reason, the Qing court mobilized a large number of troops, many of which were the main force of the Eight Banners Army led by Nikan, and it was inevitable that there would be insufficient use of soldiers and money and food, and a relatively "stable" province like them would have very few resources to be distributed.

However, the Hongyi cannon will soon arrive in Haifeng County, if it comes again to no avail, the face of Shang Geng's second domain and the Qing court will not be justified. In this case, Geng Jimao simply led the entire army of Jingnan Domain to march eastward, supplemented by Huang Yingjie, Zhang Daocheng and Hao Shangjiu to attack the Ming army in eastern Guangdong.

When the army arrived, Huang Yingjie quickly built a large camp, and then the army of Jingnan Domain settled in. Geng Jimao looked at the fortress in the distance, and his eyes were full of resentment.

In the last defeat, the soldiers of the Jingnan Domain lost no less than 800 soldiers, and if you count the deaths of wounds and diseases after the war, this number has broken through the 1,000 mark. The last time it was an army of 7,000, the loss of troops was like this, and the Qing court supplemented it from the green battalion in the north, but the first time it independently led the troops to fight, it suffered a big defeat, Geng Jimao's prestige in the army declined significantly, and the whispers of the Jingnan Domain were less, but the Pingnan Domain already had a statement that Geng Zhongming and Geng Jimao's father and son were tiger fathers and dogs.

"Virtuous nephew, it is better to attack the strong wall of the Luohe River again, it is better to attack the Sanhe Dam, and then sweep down the river and sweep Chaozhou."

"Uncle's words are wrong, with the red cannon, Haikou Castle is nothing more than paper paste. From the tide of Haifeng and sweeping the coastal counties and towns, the main force of Haikou can be intercepted on the shore and prevented from escaping from floating in the sea! ”

It's not that you really have to finish the battle, but for Geng Jimao, where you lose face, you have to take it back. What's more, with the help of these seventy-three Hongyi cannons, he didn't think there was anything terrible about that fortress.

After a few days of rest, the army approached the fortress for nearly two miles, a distance that was already out of the effective range of the Ming artillery in the last war. And the Hongyi cannon they brought this time can still effectively strike at the fortress of the Ming army.

Stroking the copper cannon body, the cold touch made Geng Jimao a little ambitious. This weapon is called the Hongyi cannon in China, and it is actually modeled after the British front-loading smoothbore cannon, and in continental Europe it is a naval gun. The Ming army mostly relied on this to defend the city, while the Qing army used it to attack the city, and the latter was obviously more able to exert its true power.

His left hand gently brushed over the smooth sound of cannons, and Geng Jimao looked at the cannons placed on the ground, all of them were black and swarthy, even if they were more than ten catties of cannons, they were particularly cute in his eyes at the moment. Raising his head and looking at the castle of the Ming army, it seems that it is slightly different from before, the shape has been added, and the original rammed earth fortress has been covered with bricks, but looking at these cannons again, I recall the old incident of bombarding the fortified city of Guangzhou two years ago, but I only have disdain.

"Let the Hongyi cannon come here, and Chen Kai's scheming will be like that."

Thinking of this, Geng Jimao also looked at the world with a majestic posture, and then stepped on the war horse again, returned to the banner of the king of Jingnan, pulled out his sword, and pointed directly at the fortress in the distance!

Note 1: The South General Soldier is the North Soldier Nan Yikui on the right side, and the Ma General Soldier is the General Soldier of Xuzhou and the Leopard. Some of the historical materials record that Nan Yikui died in this battle, but in fact, it is not, in history, Hong Chengchou established the Changsha Shogunate during the establishment of Nan Yikui as the commander of the warp standard.

Note 2: Aljin's transfer to Hanzhong and Zhuo Luo's return to Beijing are both historical facts, and the threat to the Guangdong battlefield at that time was greatly reduced with Li Dingguo's return to Huguang, and the Qing court was too busy with the affairs of the Sichuan and Huguang battlefields to take care of them at all.
