Kaesong, east of the city.

Zhang Fu, who was covered with dust, looked at the city with hatred, and spit in the direction of Kaicheng: "Li Fangyuan, count your kid's life!" ”

"Let's go!"

Looking at the Ming army that was dusting away from the city, Li Fangyuan, who had just climbed the city tower, breathed a sigh of relief, and was finally safe. The two-day and one-night escape life was finally over, and the fierce and vicious general still didn't catch up with him in the end.

However, Li Fangyuan, who calmed down, immediately realized that the trouble had just begun.

It was daytime, and many people should have seen the scene of their hasty entry into the city, and the news of their defeat and the lack of an army of 100,000 would soon spread throughout the city, and even spread to other cities.

Li Fangyuan immediately ordered Kaesong to impose martial law and not allow anyone to enter or leave, and at the same time sent people to inform Seoul and send troops to reinforce Kaesong. Hearing Li Fangyuan's stern tone, Jin Fuchuan hurriedly bowed his head and took the order, and went down to make arrangements.

......

Why did you lose so badly? Li Fangyuan never figured it out, and he thought that his battle plan was no problem.

His plan was for Bian Zhongliang to hold the city of Shaliyuan and prevent the Ming army from moving south. In this way, when the Ming army was tired from besieging the city, he secretly set out from Haizhou to reinforce Bian Zhongliang, and the two armies were attacked, and he would inevitably win a big victory. Because the combined strength of the two armies is 100,000, and the cavalry is more than 40,000, which is nearly twice the size of the Ming army, it is a sure victory from any point of view.

But it failed, and the defeat was a mess, almost the whole army was wiped out, and there were only more than 5,000 remnants of the defeated soldiers who followed him to Kaesong, and even the favored minister Nan Zai was also thrown in Haizhou, and it is estimated that there is more than one luck.

However, this plan was opposed by veterans such as Anton Xun, and the reason for their opposition was also very simple, the Ming army had strong firearms, and Sheng Yong was even more famous for attacking fortifications.

However, Bian Zhongliang tried his best to fight, believing that the power of the Ming army's firearms was exaggerated, because the effective range of the North Korean imitation artillery was only forty or fifty paces, and if the range was increased, it would often explode.

Li Fangyuan also agreed with this, because when he went to the Ming Dynasty ten years ago, he had never heard of this weapon from the mouth of King Yan, and at that time, King Yan was in control of the most powerful border army of the Ming Dynasty, and he should have used the most advanced weapons of the Ming Dynasty.

And when it came to Li Fangyuan's position, lying and covering up almost became an instinct, so he instinctively thought that the little emperor of the Ming Dynasty was exaggerating to prove his wisdom and martial arts, which was also something Li Fangyuan himself often did.

Of course, there are also many people of insight who pointed out that the guns on the battleships of the Ming army's naval divisions were powerful, but according to the descriptions of the survivors, that kind of artillery was only spraying stones and lead bullets, and it could not be said to penetrate the city wall.

In the end, Li Fangyuan made up his mind to defeat the Ming army in Shali Courtyard City as a sacrifice for his accession to the throne.

As a last resort, An Dongxun and other veterans retreated to the next best, suggesting that Li Fangyuan's main force hoard the Hukou Pass, and once the battle situation is unfavorable, they can also hold the front line of the Evil Mountain Range (Mercy Ridge).

However, Li Fangyuan disagreed, he thought that this was obvious, and the art of war was to pay attention to attacking it unprepared, and the Ming army would definitely guard against the attack at Hukou Pass, but not against Haizhou. And Li Fangyuan insisted on Haizhou for another reason, that is, to prevent the Ming army from landing from Haizhou Port. In addition, he believes that Haizhou is only two hundred miles away from the city of Shaliyuan, and it will take one day to get there in one day and two days to get there.

Although the veterans were still a little hesitant, Li Fangyuan insisted, and they had no choice but to agree. In addition, they also have their own careful thoughts, they feel that they can teach Li Fangyuan a lesson through this matter, so that he can pay attention to the role of veterans, rather than blindly reusing young generals, which Li Fangyuan and Bian Zhongliang actually know, which also stimulates their ambitions.

However, the development of the battle situation was beyond everyone's expectations, the power of the Ming army's firearms greatly exceeded the imagination of Li Fangyuan and others, in the rumbling cannon, the Korean cavalry, which was inseparable from the Ming cavalry, quickly collapsed, and then the Ming cavalry was endlessly pursued......

In the next few days, news came one after another that Hukou Pass and Haizhou had been lost, and the Ming army also temporarily stopped at the Evil Mountain Range, but its cavalry Zhang Fubu did not stop, and appeared around Kaesong from time to time. Li Fangyuan sent cavalry to attack, but he lost more than he won, and finally had to close his door.

After that, the North Korean "Guiyi Army" began to collect grain and grass around Kaesong and catch strong men, although Zhu Yunwen gave them only enough food and clothing, but Sheng Yong was "considerate" let them be responsible for collecting grain and grass and strong men, they could keep half of the grain and grass, and a strong man could exchange one month's rations, if it was a complete family, it could even be exchanged for two months' rations.

At first, the Guiyi Army was a little embarrassed, thinking that it was not moral enough. But the first guard of Viscount Xu Bao of the Ming Dynasty took the lead and returned with a full load, in exchange for a large amount of provisions. After seeing the canned food, meat floss, fried cakes, and even armor, bows and arrows obtained by the first guard, other soldiers of the Guiyi Army also joined the battle and fought hard. In this way, the common people around Kaesong suffered, not only the food was robbed, but the people were also plundered in large numbers. After Li Fangyuan heard the report, he sent troops to attack, but he was repeatedly ambushed by Zhang Fu, and the rescued people could not be resettled. In the end, Li Fangyuan had no choice but to order the people to retreat in the direction of Seoul and Jeolla Province to avoid the Ming army!

In this way, a wave of refugees naturally formed south of Kaesong.

The Ming army loaded the looted Korean people onto ships and transported them to Taiwan, Hainan and Yunnan, where they planted sugarcane and tuntian, contributing to the construction of the Ming frontier.

......

Li Fangyuan was annoyed, and couldn't help but set his eyes on the Han River, but unfortunately the news from there was also depressing.

July is the rainy season in North Korea, and the water of the Han River has risen sharply, and many of the wooden stakes nailed by Li Fangyuan have sunk underwater, which greatly increases the difficulty of the sailors to clean the wooden stakes. But the Ming sailor had already prepared, using a tortoiseshell boat to clean the stakes, the specific method was to use a rope to cover the stakes, and then drive the boat downstream, the water flow plus the power of the propeller, you can easily pull out the stakes.

As for the wreck, in fact, the damage is much less, and after the stake is cleared, it can be pulled to the shore. But for the time being, you can only mark it first to avoid stranding.

Li Fangyuan not only sank the ship in the Han River, but also carried out fortified clearing on both sides of the river, and finally deployed troops to harass him. But they were all repelled by Zhang Lun's guards. As the "first" army of the guards, Zhang Lun's subordinates were equipped with the most new firearms and the most advanced, the muskets were all flintlock muskets, and there were as many as 200 mortars, which was almost equivalent to the number of Sheng Yong's entire army.

Therefore, the North Korean army in charge of harassment could not get close to the shore at all, and could only watch the Daming Navy Division clearing the channel unhurriedly. Moreover, shipwrecks and nailing wooden piles also require a lot of materials and manpower, so Li Fangyuan's arrangement is mainly concentrated in several places such as the estuary of the Han River, Kaesong, Ganghwa, Gimpo, and Seoul.

More than 20 days later, the head of Kaesong could already see the figure of the Ming army's sailors cleaning the wooden stakes, and Zhang Lun's guards were gradually approaching the outskirts of Kaesong. Faced with a grim situation, Li Fangyuan hesitated again and again, leaving 20,000 people in Jin Fuchuan to guard Kaesong, and led his army to retreat to Seoul to avoid being caught by the Ming army.

On July 26, the sixth year of Jianwen, Sheng Yong, Zhang Lun, and Luo Kening met under the city of Kaesong, and surrounded the city of Kaesong, but Li Fangyuan was unable to reinforce it, because the control of the Han River was completely controlled by the Daming Navy. As for the Korean naval division under the city of Kaesong, it has long been wiped out in the sound of artillery.

Sheng Yong still attacked the city in the old way, suppressed the city head with muskets and artillery, and then let the Guiyi army ants attach to the siege city. However, Kaesong used to be the royal capital of Goryeo, the city was tall, and the guard Kim Fuchuan led by example, eating and living on the tower day and night, pacifying the soldiers and motivating the army, so the defenders' will to resist was very resolute, plus the Guiyi army who attacked the city, some were the objects of hatred of the defenders of Kaesong, because they were not only traitors, but also robbed the Korean people, so the people who fled to the city spontaneously went to the city to assist the defenders to defend the city. The Guiyi army suffered repeated setbacks in the siege of the city, with heavy casualties......
