Zheng Hongkui's naval division, because it was going to enter the Yangtze River to fight, the ships were relatively small, and the warships were basically the No. 2 Fu ship.

The No. 2 Fu hull shape is wide at the bottom, the bow is raised and open, the tail is towering, the draft is about more than one zhang, the bow is equipped with one Hongyi cannon, six thousand catties of Franc machines, three bowl-mouth guns, about 20 thunderbolt cannons, and 60 spray canisters, 10 gunguns, 500 crossbow arrows, about 10 gunpowder machine crossbows, more than 300 rockets, more than 100 fire bricks, and more than 1,000 other swords, guns, swords, and halberds.

Zheng Hongkui had about 100 of the No. 2 Fu ships, and there were about 150 small warships and chain ships such as the Haicang Ship, the Grass Skimming Ship and the Cangshan Ship, and 57 sand ships transporting troops.

Such a fleet size is already an invincible existence on the Yangtze River, Zheng Hongkui after receiving the news that the main force of the Jingbei Army crossed the river, he knew that it was no longer meaningful for him to stay in the southern capital, and the best choice at this time was to evacuate Baguazhou and return to Fujian along the east of the river, otherwise the supply would be cut off, wouldn't it be to go back hungry.

On 5 July, the Baguazhou Zheng Army's naval division pulled anchor and set sail, and the next day after converging with Si Yezhou to stay in Shilang, he immediately withdrew to Chongming Island and the Yangtze River estuary.

On 13 July, Zheng's naval division finally arrived at Chongming Island, located at the mouth of the Yangtze River, after passing through Jiangyin and Suzhou Creeks.

Clinker, Xu Ding of Chongming Zhixian County, as well as Zhang Shiyi, the chief soldier of Huaihe Town, Zhang Pengyi, the chief soldier of Huaihai Town, and Shi Hongshi, the deputy general of Chongming, and other officials of the Southern Ming Dynasty who had been extremely flattering to Zheng Hongkui before, actually closed the door to the Zheng army who asked for grain and straw on the island, and detained the envoy of the Zheng army.

"Xu Ding, does this want to die? Shi Lang and Yang Qiu, you quickly went to the island and took the heads of Xu Ding and the others to the general. ”

Zheng Hongkui was furious when he heard the report, the Zheng family has been crisscrossing the southeast coast for more than ten years, and the governors of various places do not sell the Zheng family a little face, and now a small magistrate actually dares to resist the army of the party, which is really lively.

"Zheng Shuai, although the county seat of Chongming is not very strong, but Zhang Shiyi and others still have more than 3,000 soldiers and horses in their hands, in order to prevent changes, we still have to disassemble some of the Hongyi cannons, otherwise I am afraid that we will not be able to take the county seat for a while and a half."

Shi Langzi Zunhou, known as Zhuo Gong, a native of Jinjiang County, Quanzhou Prefecture, Fujian Province, has been following Zheng Zhilong in the early years, proficient in water warfare, not only in Nanyang and the Portuguese and Dutch, but also with the Ming Dynasty Fujian Navy also fought a number of battles, in his opinion, although Chongming County is a soil city, but Zheng Jun is not good at land warfare, if there is no artillery cooperation, it is impossible to take Chongming City.

Zheng Hongkui nodded and said: "What General Shi said is reasonable, in this way, you will disassemble twenty heavy cannons from the ship, and you must break Chongming today, I will let Xu Ding's old boy know that my Zheng family should not be humiliated." ”

"Zheng Shuai, Xu Ding is unusual, is there something to rely on, the last general thinks that we have to guard against it."

Yang Qiu is a native of Anping, Fujian, and Zheng Zhilong is a fellow villager, known as a strategist, although he has no doubts about Zheng Jun taking Chongming City, but the abnormal behavior of Xu Ding and others makes him suspicious.

Zheng Hongkui said with a smile: "Brother Yang is too worried, according to Ben Shuai's estimate, Xu Ding, Zhang Shiyi and others saw the Northern Army drinking the Yangtze River, and gave birth to the thoughts of both ends of the first rat, the Chongming River is open and close to the sea, who dares to come to pick the tiger whiskers of our army's sailors." ”

"Yes, although our land battle is not the opponent of the Northern Army, in terms of naval warfare, it is the arrival of the Northern Army's naval division at the mouth of the Yangtze River, isn't it the same as playing for us to fight them?"

Shi Lang laughed, the Zheng family sailor was not blown out, but in Nanyang and the Franco people really fought each other, as strong as the Franco and the Dutch sailors, they were all in front of the Zheng family's sailors, even if the Northern Army sailors arrived, he was confident enough to win the battle.

"Then, General Shi, let's act quickly, it will change later."

What Zheng Hongkui and Shi Lang said was unreasonable, and Yang Qiu couldn't insist anymore, but he was still a little worried, so he asked for a quick solution instead.

Seeing that the generals had unified their opinions, Gu Zheng Hongkui opened his mouth and said: "Send the order to go down, immediately seize Chongming Nanxinkou and disassemble the artillery." ”

With Zheng Hongkui's military order, the Zheng family sailors immediately turned around and went straight to Nanmen Port, in fact, Chongming Island is the largest island at the mouth of the Yangtze River, and there are countless ports that can load and unload materials, but only the geographical location of Nanmen Port has the best hydrological conditions, which is suitable for berthing a large number of ships.

Moreover, Nanmen Port is a concave-shaped deep-water port wharf, with a width of nearly two miles, and a concave part of more than ten miles, and the river surface in the port is relatively stable, which has almost no impact on the loading and unloading of artillery by Zheng Jun.

Xu Ding was obviously afraid of the Zheng army, and did not divide the troops to occupy the key points, and only deployed a hundred households in Nanmen Port to be responsible for military information.

Zheng Hongkui hated Xu Ding and the others deeply, and after the fleet docked, he strictly ordered all departments to immediately light a fire to make food, and when Lu Shi had a good night's rest, he would take Chongming City directly.

Of course, he didn't trust the university, and still strictly followed the training and drill rules of the Zheng family's sailors, and sent ten sentinel ships outside the port, which were led by Lin Mingzhong, a hundred households of the Zheng army's sailors.

Lin Mingzhong was also slandered by Zheng Hongkui's military order, what kind of sentinel ship to send? It's all at the mouth of the Yangtze River, what's there to be afraid of, together with you all resting on land, we have to continue to stay on the boat to patrol, but the official is crushed to death, Zheng Hongkui is Zheng Zhilong's younger brother, the number three person in the Zheng army, he didn't dare not agree at all except for cursing a few words secretly.

The fact is the same as Lin Mingzhong expected, Zheng Jun's sentinel ship inspected the Yangtze River for more than ten miles, and did not find any clues, until the sun was about to set in the west, Zheng Jun's sentinel ship returned to Nanmen Port.

But what happened to Zheng Hongkui and Shi Lang's surprise still happened, the next day, just as Zheng Jun was preparing to send troops, a black sail suddenly appeared outside Nanmen Port, and then countless warships appeared in the slightly white sky, like a blockage of wooden city in the direction of Nanmen Port, pressed over, looking at the meaning of this fleet, it was obvious that it was to blockade Nanmen Port.

"There is an enemy...... Fast...... Hurry up and report to Zheng Shuai.

The observation post on the Zheng army's warship looked at the slowly approaching black line in surprise, picked up the clairvoyant mirror in his hand again, and after observing, he suddenly roared in horror.

"Bell...... Clang...... Clang......! ”

The herald at the observation post also saw the black line that was getting closer and larger, and after being confirmed by the sentry, he hurriedly sounded the gong for alarm.

Zheng Jun's sailors were well-trained, one ship gave an early warning, and the rest of the warships also sounded the alarm one after another, especially the sailors on the No. 2 Fu ship, after hearing the alarm, they had already raised their sails, and the artillerymen also moved boxes of guns out of the cabin and prepared in an orderly manner.

"What...... Enemy situation, hurry, hurry up and get on the boat with Lao Tzu, ready to fight! ”

Zheng Hongkui, who was just about to take the oath on the shore, was shocked, because when the sentinel boat called the police, he saw the fleet coming on the river.
