After Wang Wei and Wang Yan separated, they urged the 4,000 infantry troops of the Zhongyi Battalion to rush to Yangzhou, but because of the artillery team and baggage, and the rain for several days, the march was very slow.

When Wang Wei braved the rain and dragged mud all the way to Zhenjiang, it was already May 1, and Wang Yan had been holding on to Yangzhou for six days.

When Wang Wei arrived, Liu Liangzuo's troops also rushed to the outside of Yangzhou.

Liu Liangzuo is a native of Shanxi Datong Zuowei, Chongzhen period in Susong, Luzhou, Lu'an area with the peasant army to fight, promoted to the chief officer, when the northern capital fell, he garrisoned near Zhengyang, Henan, he did not Qin Wang.

After the Jiashen Incident, Ma Shiying, the governor of Fengyang, in order to prevent the Shun army from attacking Jianghuai, recruited Liu Liangzuo to lead his troops into Weinan Zhili, and he burned and looted all the way into the Jianghuai area.

When Liu Liangzuo's soldiers arrived in Linhuai, the people heard that his military discipline was extremely poor, and they were robbed by his soldiers and horses along the way, and they did not dare to let him enter the city.

Liu Liangzuo saw that the people were sticking to the city, and he was furious and sent troops to attack it, but he couldn't attack it for a long time, Ma Shiying hurriedly came forward to mediate and let him move to the area of Shou County.

During the Fulu dispute, Liu Liangzuo felt that it was profitable to support Fu, so he had to be named Guangchangbo, and after dividing the station, he had been threatening the court by force and asking for money and food.

When the left went east, he did not do his best, although Liu Liangzuo was nominally a minister of the Ming Dynasty, but in essence he was a speculative warlord and had no loyalty at all.

Liu Liangzuo's surrender to the Qing Dynasty was not accidental, in addition to the fact that he was originally a speculator who pursued advantages and avoided disadvantages, his younger brother Liu Liangchen also played a great role.

In the fourth year of Chongzhen (1631), during the Battle of Dalinghe, Liu Liangchen was a guerrilla general under Zu Dashou, and after the defeat, he surrendered to the Qing court.

The Qing army went south and besieged Yangzhou, Liu Liangzuo felt that the general trend of the Ming Dynasty had gone, and it happened that the Qing court sent his brother Liu Liangchen to come to surrender, promising to raise the flag and be knighted.

Liu Liangzuo wanted to find another way out and escape from the broken ship of the Ming Dynasty, and the two sides immediately hit it off.

In addition to bringing out 40,000 soldiers and horses from Chizhou, Liu Liangzuo Town also had nearly 60,000 soldiers in the area of Shouzhou, where he was stationed in Jiangbei, totaling 100,000 horses and horses, all of which were returned to the Qing court.

Wang Wei's troops went to Zhenjiang, and Liu Liangzuo also rushed to Yangzhou with 40,000 horses to wait for the dispatch of the new master, Duoduo.

Yangzhou could not be attacked for a long time, Duoduo was worried that the Ming army on the south bank would cross the river to support, and when he was anxious, Liu Liangzuo led the troops to arrive and asked him to add 40,000 soldiers, which made Duoduo very happy.

Liu Liangzuo's 40,000 horses were deployed along the north coast of the Yangtze River, but the Ming reinforcements in Zhenjiang City only had 4,000 loyal battalion infantry troops brought by Wang Wei.

Since Zheng Hongkui reported to the imperial court for reinforcements, there has been no support in Zhenjiang except for Wang Wei's troops, but the strength of the Qing army outside Yangzhou City has been increasing.

Since Duoduo played Dolgon, asked for reinforcements from Shandong, and attacked the south, the Qing court was running at full speed.

On 2 May, Dolgon ordered the commander of the Gushan Ezhen Zhun Tower in Shandong to go southeast from the mountain and collect Li Chengdong and other high-ranking generals.

Liu Zeqing, one of the four towns, heard that the Qing soldiers were approaching Huaiyang, and he had no heart to resist, so he hurriedly handed over the land, people, soldiers, horses, money and grain of the 14 prefectures and counties of Huaiyang to Bai Yongfu, the chief soldier under his command, but he fled to the sea by boat with Wang Yongji, the governor of Shandong, and Tian Yang, the governor of Caodu.

Wang Yan was trapped in Yangzhou, the news was blocked, and he didn't know that the situation faced by Daming had not changed much because he occupied Yangzhou, and he was still stormy and dangerous.

At this time, he was on the west city, watching the artillery team, and engaged in an artillery battle with the Qing army's artillery array on the high slope of the west city.

The artillery of the Qing army, placed on the high slope outside the west city, can overlook the city, pointing where to fight, it is very unfavorable to the defenders of the west city, especially the northwest gap, which has not been repaired so far, and hundreds of thousands of defenders will be killed in the tug of war every day, which is more than the total number of Ming troops killed in other directions, which is extremely unfavorable to the defense of the city.

Wang Yan wanted to change the unfavorable situation, either to lay down the high ground outside the west city, or to use the artillery on the city to suppress the Qing army's artillery array, but Duoduo knew the importance of the high slope, and had already sent heavy troops to defend it, and the Ming army in the city was mostly new pawns, and it was okay to refuse the city and defend it, but he couldn't beat the Qing army in the battle out of the city, so he had no chance to take advantage of it, so he could only rely on the artillery on the city to bombard the Qing army.

Wang Yan was not proficient in artillery warfare, so he had been pressed and beaten by the Qing army's artillery before, but fortunately He Gang recommended to him, Chen Yujie, the secretary of the military department, and slowly reversed the disadvantage and barely fought a draw with the Qing army.

Wang Yan saw that Chen Yujie commanded the artillery team handily and was a hundred times stronger than him, so he was naturally happy in his heart, and after some understanding, he learned that Chen Yujie was the nephew of Yu Guangqi, the late important minister of the Ming Dynasty.

Xu Guangqiguan to the Chongzhen Dynasty Rite Department Shangshu and Wenyuan Pavilion University Scholar, Cabinet Assistant, is also a famous scientist, proficient in Western studies, good at casting cannons and firearms, Chen Yujie has been influenced by it since childhood.

He has extensive knowledge, is familiar with astronomy, is familiar with the secrets of the use of guns in the West, is good at city defense, has made great contributions to the imperial court, and was awarded the title of Doctor of Qin Tianjian by the imperial court.

After the martyrdom of Emperor Lie, Emperor Hongguang succeeded to the throne, he was exiled to the south, and was recruited to Yangzhou by Shi Kefa, as the secretary of the military department, responsible for training soldiers to use muskets and artillery.

When the Qing army besieged Yangzhou, he happened to be trapped in the city and was rescued by the officers and soldiers of the Zhongyi Battalion.

Firearms are a sharp weapon for defending the city, and Wang Yan can get a talent like Chen Yujie, so he naturally has to reuse it and command the artillery team as he is ordered.

Yangzhou inside and outside the city of artillery sound, staged a big battle related to the life and death of the Ming Dynasty, in Hubei, Jiangxi, another relationship to the life and death of Dashun, also entered the end.

In March, Zuo Liangyu received a secret edict from Emperor Lie's "crown prince" under the pretext of raising the banner of rebellion, and the whole army went east by boat and set fire to Wuchang.

Li Zicheng led a large army into the city of Wuchang, which had become a red land, and soon after, the Qing army of the Azig Department tracked down and besieged Wuchang.

Li Zicheng ordered Liu Zongmin and Tian Jianxiu to lead 5,000 men and horses to fight, but they were defeated by the Qing army, and he was immediately frightened, and did not dare to fight with the Qing army again, so he continued to go east with the abandonment of Wuchang.

At this time, the situation of the Dashun army was already very difficult, and the four prefectures of Jingxiang easily fell into the hands of the Qing army, not only did not hinder the Qing army, but lost all the logistics and supplies.

The Dashun army had to protect the families of the army, guard against the Qing army, and think of raising food for the more than 100,000 troops, and the command was suddenly chaotic.

The Dashun army invaded Jing and Yue, and went down to Qi and Huang, raising grain everywhere, and there was a chaos, and there was no clear direction of operation.

In early April, the Dashun army was again caught up by Azig at Fuchikou in Yangxin, and unsuspectingly, the camp was broken by the Qing army and suffered heavy losses.
