The Yangtze River is a moat, and how many dynasties have survived on it.

But even the moat has to rely on people to defend, as long as the enemy also has ships and naval forces, the vast Yangtze River can be crossed everywhere.

Although the combat strength of the naval army led by Zheng Hongkui is not bad and the number of people is enough, after all, it is a guest army, and the time for being hastily requisitioned is too short, and a solid defense line has not yet been built.

And the Qing army was also very bold, and dared to cross the Yangtze River at night to launch a strong attack. Once the Ming army is relatively well prepared, if it has built a strong camp to defend it, and then sends warships to block the river, the green battalion soldiers sent by Bolo will return in vain, and the heavy ones will be in danger of being wiped out.

Because the Green Battalion soldiers were not regarded by Bolo as their own people, they were not distressed even if they were all lost, so they made this bold sneak attack plan, and it succeeded.

The Green Battalion successfully defeated the Zheng family's naval army, and Zheng Hongkui led the fleet down the river and fled in the direction of Zhenjiang.

Bo Lo reported the great news, and led 5,000 Eight Banner soldiers to cross the Yangtze River by boat, and stationed on the northwest side of Nanjing City, only a few miles away from the Guanyin Gate in the outer city of Nanjing.

In the north of Nanjing, countless defeated soldiers walked in the fields, and it was the defeated Zheng family soldiers.

The riverside camp they were stationed in was less than ten miles away from the city of Nanjing, and many of the defeated soldiers instinctively wanted to escape into the city, but found that the gate of Nanjing was pressing, and they were not allowed to enter the city at all, so they could only reluctantly walk around the city and retreat to the east.

Fortunately, the Green Battalion soldiers did not send troops to chase and kill, which gave many defeated soldiers a sigh of relief.

What's next? The routs were at a loss.

Zheng Hongkui, the commander of the army, fled down the river by boat, and they lost their command, and the generals of the battalions gathered together to discuss the next move, but they couldn't come up with an idea, and they didn't know what to do.

"Why don't we go back to Fujian." Guerrilla general Guo Ting proposed.

"No, in that case, you will be severely punished by the imperial court." Another guerrilla named Liao Jing objected.

There were more than 10,000 troops who escaped and gathered together, and Guo Ting and Liao Jing had the highest military ranks.

"Imperial court! It's not sure how many days the imperial court can exist, haven't you heard that the Qing army on the west road has broken through Jiujiang, Zuo Liangyu's hundreds of thousands of troops have all surrendered, and Yangzhou has also been surrounded by Qing soldiers, and now the Qing army has crossed the Yangtze River to attack the city of Nanjing, and the imperial court can't hold it. ”

Guo Ting shouted in despair. Now if you don't flee quickly, after the Qing army crosses the river in a big way, you won't be able to escape if you want to.

"What if Nanjing can be held? At that time, it will not be severely punished by the imperial court, and it will also bring disaster to the chief soldier and the fourth master. ”

Liao Jing instinctively hesitated, the majestic city wall of Nanjing City not far away made him fearful, such a high and thick city wall might really be able to block the attack of the Qing army.

"Two generals, the eldest prince is here." Just as the two were arguing, a small soldier suddenly came over to tell him.

The eldest son? The two were shocked, and hurriedly turned around to look, and saw Zheng Sen appear in front of them in white. The straight body and handsome face like a knife and an axe are Zheng Sen, the eldest son of Zheng Zhilong, the general soldier of Fujian.

"Eldest Prince, why are you here?" The two hurriedly greeted each other and exclaimed in surprise.

Zheng Sen should be studying in Nanjing City right now, how did he go out of the city and come to the army?

"I have seen two uncles, the war by the river is in full swing, I was restless in the city, so I went out of the city and came here."

Liao Jing and Guo Ting are both old pirates who started with Zheng Zhilong, and Zheng Sen is called his uncle, and the two dare not even shout.

Zheng Hongkui led the navy from Fujian to Nanjing, Zheng Sen, who was studying in Guozijian, naturally knew about it, and when Zheng Hongkui was summoned to the city to meet a few days ago, the uncle and nephew also met.

Outside the city, his own soldiers on the riverside were fighting against the Manchu Tartars, and Zheng Sen had no intention of studying and was always concerned about the battlefield situation.

Hearing the news of the defeat of the Zheng family's army early this morning, Zheng Sen was shocked and hurriedly asked to see his mentor Qian Qianyi, who told Zheng Sen that the imperial court was discussing how to deal with the Qing army crossing the river, and was very dissatisfied with Zheng Hongkui.

Zheng Sen asked Qian Qianyi to go out of the city to collect the rout, and fight fiercely with the Qing army to be ashamed.

The defeated troops outside the city naturally had to be settled, and it was best to urge them to return to the battlefield to continue to serve the imperial court, and for the sake of safety, they could not open the city and let them enter Nanjing. Zheng Sen is the son of Zheng Zhilong and a student of Guozijian, so it is also a good choice for him to come forward to appease the rout.

After Qian Qianyi and the first assistant Shi Kefa discussed, he gave Zheng Sen a temporary official position as an inspector and ordered him to go out of the city to collect the Zheng family's rout.

Zheng Sen took two entourages to the outer city, went out of the city through the Qilin Gate, and found here.

Now that Zheng Sen has an official identity and is the son of Zheng Zhilong, after Liao Jing and Guo Ting looked at each other, they could only obey the order solemnly and hand over the command to Zheng Sen.

After Zheng Sen obtained the command of the more than 10,000 defeated troops, he reorganized the more than 10,000 defeated troops into three battalions with Liao Jing and Guo Ting as the commanders of the left and right battalions, personally led the middle battalion, and assisted himself with Chen Hui and Zhou Rui as deputy generals.

At the same time, Zheng Sen ordered people to send a letter to Zheng Hongkui along the river, asking him to lead the fleet back to Nanjing as soon as possible.

After organizing the army, Zheng Sen immediately led the army to launch a counterattack against the Qing soldiers, and fought with the green battalion soldiers by the river, and finally lost the enemy, so he could only stand outside the Guanyin Gate and rely on the support on the city wall.

Hearing that the imperial court actually appointed Zheng Sen to lead the Zheng family's army, and Zheng Sen was leading the rout and the Qing army to fight fiercely, Zheng Hongkui, who was about to flee to Zhenjiang, was shocked, for fear that Zheng Sen would lose, and hurriedly led the fleet back to the division, and had a continuous fierce battle with the Green Camp Navy on the Yangtze River, and the two sides won and lost each other.

Zheng Senbu, who was stationed outside the Guanyin Gate, was like a nail firmly nailed outside Nanjing, making the Qing army extremely uncomfortable.

More than 30,000 Qing troops were distributed on the riverside in the northwest of Nanjing, so close to the Nanjing city wall, but they were helpless in the face of Nanjing's fortified city.

The imaginary momentum is like a bamboo, and the Ming army has surrendered one after another, and it is a joke that the soldiers entered Nanjing without blood, because the emperor in Nanjing is now Chongzhen, not King Fu.

Although the Qing army crossed the river, the hearts of the people in Nanjing fluctuated, but the phenomenon of large-scale surrender in another time and space did not appear.

In fact, it is difficult to eat even Zheng Sen's more than 10,000 defeated troops now. When sending troops to attack, the attacking army was repeatedly attacked by the city's artillery fire, and with the protection of the city's head, it was difficult to defeat Zheng Sen's army.

At first, he was ambitious to cross the river and successfully defeated the Zheng family's sailors, but now Bolo feels like he is sitting on wax.

The city wall of Nanjing is extremely strong, and there is the Zheng family's army outside the city, with his 30,000 people, it is simply wishful thinking to take down the majestic city of Nanjing.
