On September 24, Hanyang fell, and on September 26, Yingordai found the whereabouts of the Joseon king from a group of slaves, some of whom had gone to work in the fields in the early morning of the previous day, watching a group of cavalry defending several nobles fleeing in the direction of the mountain fortress of Namhansan, and there were nobles in red python robes in the procession.

Listening to the costumes described by these slaves, Ying Erdai knew that the one wearing the big red python robe was the king of Joseon. In North Korea, except for the king of Joseon, no one dares to wear this costume to travel.

On September 27, Dolgon personally led his army to block the road to the mountain fortress of Namhan, and after some probing, it was confirmed that the Joseon king Yi Liang was indeed inside the mountain fortress.

Located on the top of Namhansan Mountain, the mountain fortress was originally an earthen fortress from the Goguryeo period, but it was finally built in the hands of Gwanghaejun after being renovated and strengthened over the years. The mountain fortress is surrounded by the highest peak, Iljangsan Mountain, and if you climb the highest peak, you can see the sunset as far as Incheon, as far as Seoul and Gyeonggi Province.

The perimeter of the whole city is high and dangerous, and the middle of the city is low and easy to defend. The city is divided into an inner and outer city, with a circumference of 9.05 kilometers and a height of 3-7.5 meters, which is long from east to west and short from north to south. The inner city is home to a palace and various facilities used by the royal family for evacuation. Li Liang fled here, which can be said to be a lot more relieved.

However, although this mountain fortress was built for the refuge of the Joseon royal family, Li Liang hated this place very much, because it was built by Gwanghaejun, so the materials and garrison troops in the mountain fortress have not been replenished according to the standard. Li Liang didn't think that he would really be useful for a day here, so when Dolgon blocked the road up the mountain with a large army, Li Liang was worried about whether he could defend the mountain city.

Jin Shangxian and Shen Qiyuan, who also fled into the mountain city, are still fighting with one force, but Li Liang's heart has begun to lean towards Cui Mingji's peace proposal. It's just that the main battle factions of Jin Shangxian and Shen Qiyuan are stronger in the mountain city, so Li Liang still listened to Jin Shangxian and Shen Qiyuan's proposition in hesitation, and stuck to the mountain city and waited for reinforcements. And once again, he selected the warriors to go over the mountains and mountains to each province to pass the order, asking each province to send reinforcements to rescue Namhansan Fortress.

On October 1, Hwang Tae-gil led the main force of the rear army to Hanyang Fortress, and after he arrived in Hanyang, he formulated a strategy to encircle the point and send reinforcements, so that Dolgon blocked the road to Namhansan Fortress with bamboo and wood, and then attacked around Namhansan Fortress to defeat the Korean volunteers who came to help them one by one, so as to prevent these volunteers from gathering together.

In addition, he also appeased the Korean officials who had been captured at the time of the destruction of Hanyang City, and although the leader of the council and the capital of the capital had made Kim Ryu refuse to surrender to Hwangtaeji, as a prisoner of the Later Jin, he could not prevent other officials from issuing a proclamation in his name to reassure the people, and from the Zhuju counties north of the Han River, except for some areas of Hamgyong Province and Gangwon Province, they began to obey the orders issued by the Later Jin to levy labor for the Later Jin army and provide rice and grain and other materials.

On October 15, Dolgon defeated the last two rebels from Gyeongsang and Jeolla provinces, and no more rebels came to the rescue of Namhansanseong. Kim Zidian, who was sitting on the two armies of Hamgyong Province and Gangwon Province, as the marshal of the Korean capital, refused to send a single soldier to the south to rescue, but blindly hid in the fortified fortress of Gangwon Province to protect himself.

However, although the Later Jin Dynasty conquered almost four of the eight provinces of Korea, except for 500,000 to 600,000 taels of silver and more than 200,000 taels of materials found in the Changdeok Palace in Hanyang, the treasury of other prefectures and counties had almost no income. Not only did the tax grain from Jeolla Province and Gyeongsang Province in the south not be transported to Hanyang, but even the grain from Chungcheong-do and Gangwon Province was purchased and transported to Geoje Island in the south, saying that it was used to feed the newly established Korean navy.

This situation made Huang Taiji feel tricky, and the Houjin army crossing the Han River was almost the limit in his heart. If you go further south, the army will be too long, and once the Ming navy cuts off the Han River, Huang Taiji will have to worry about the safety of his army.

In fact, he did not think that this was a good time to go to Korea, and if he had a choice, he would prefer to postpone the expedition until December, when the entire Korean waterways would be frozen, so that the rivers would not become an obstacle to the Houjin army.

For example, the families of the Joseon royal family and the two classes of nobles who fled to Ganghwa Island had difficulty using the strait separated from the mainland to stop the Houjin army's attack. Because there is no freezing on the sea now, the Houjin army can only look at Ganghwa Island across the strait, and sit and watch the ships of the Ming Army and the North Korean Navy protect Ganghwa Island.

But in order to reap the harvest of this year's autumn harvest in North Korea, Hwang Tae-gil had to go south in advance, counting on subsidizing the expenditure of military rations from the North Koreans. However, the emptiness of the state and county treasury made it increasingly difficult for Huang Taiji and the Later Jin army to maintain a style of not committing crimes with the people.

Far from Hwang Tae-gil's sight, the Later Jin army began to loot the estates of two classes of nobles and Korean merchants. Although the state and county treasury were empty, in the estates of these two classes of nobles, the grain was piled up. These manors are also grain depots that Lin Qingye cannot move.

On October 20, the Uzhen Chaoha troops arrived in Hanyang with 8 Hongyi cannons. Hwang Tae-gil then ordered a Korean official to enter the mountain fortress of Namhan, and demanded that the king of Korea immediately descend the mountain and surrender, otherwise he would use force to attack.

After listening to the official describe the power of the Hongyi cannon, Li Liang finally changed color. He quietly summoned Cui Mingji and ordered him to go down the mountain to make peace with Huang Taiji.

On October 22, Cui Mingji met Huang Taiji at Changdeok Palace in Hanyang, and Huang Taiji proposed to him: surrender out of the city, serve the Qing Dynasty as Zhengshuo, and pay the seal letter given by the Ming Dynasty to the Qing Dynasty and other more than ten peace conditions.

The peace conditions brought back by Cui Mingji naturally angered the main battle faction in the city, and even Li Liang was worried about what to do if Houjin regretted it after he left the city.

So under the fierce resistance of Jin Shangxian, Shen Qiyuan and other main battle factions, Li Qi repented and suspended the peace talks. On October 25, due to Lee's capriciousness, Hwang Tae-gil finally ordered his army to start attacking Namhansanseong. Although the mountain road was difficult and dangerous, the Houjin army still reached the bottom of the mountain fortress of Namhan within 10 days, breaking down the barriers on the mountain road outside the city one by one.

Although there were still more than 10,000 men and horses in the city, there was little food left, and then the Jin army transported the Hongyi cannon up the hill and aimed at the city of Namhansan. This time, Huang Taiji sent the general Jin Liu, the political council, to the mountain to make one last persuasion.

The courage of the Jurchens in the past ten days has left an extremely shocking impression on the officials of the main battle faction in the city. In particular, when Houjin set up the Hongyi cannon on the top of the mountain and aimed directly at the city, many officials finally changed their position, thinking that it was important to bend the knee to Houjin first to protect the sect.

Jin Liu cried to Li Liang: "... The matter is urgent, and it is imperative to ask for peace. ”

The Great Priest Yin Huang also advised: "Your Highness is a member of the Sect Society, if you die here, what should the people of the country do..."

The turn of these main battle faction officials finally overwhelmed Jin Shangxian, Shen Qiyuan and others who were still waiting for reinforcements from the Ming State. Although Li Liang cried to the ministers: "Three hundred years of blood sincerity is great, and he has been deeply favored, and once he will be a concubine, isn't it painful?" But he soon ordered Choi Mingji to negotiate with Hou Jin about surrendering.

Before Cui Mingji was about to leave the mountain city, Shen Qiyuan ran to grab the reins of his horse and said: "Cui Jushu, if you go like this, in the future, when the Ming Dynasty is held accountable, how should I deal with North Korea?" His Majesty the Emperor is wise and brave, how can he tolerate our North Korea's betrayal of the Ming Dynasty? Cui Jushu, don't forget, at this moment, Ganghwa Island is still under the protection of the Ming army, if His Royal Highness surrenders, how should the concubines, princes, and kings on the island deal with themselves? ”

Cui Mingji's face did not change, but he sighed and said: "The pine trees on Nanhan Mountain are frosty and proud of the snow, and they are not broken by the wind, which makes my generation yearn for it. But North Korea is not a pine tree, we are just a weak grass, and we need to bend down in time to survive in the face of strong winds.

Whether it is the Later Jin or the Ming Dynasty, they are all great powers that North Korea cannot resist. We have not chosen the power to stand on that side at all, and obeying the mandate of heaven and bowing to the strong is the way to protect the monarch and the people of the country. Shen Shen judges, you still don't understand? If there really is a so-called Ming reinforcement, how can we be surrounded here by the Houjin army? ”

Shen Qiyuan's hand slipped off the reins of his horse, and Cui Mingji urged his mount to walk out through the open city gate. On 1 November, the Houjin army set up an altar at Samjeondu, southeast of Seoul, to accept the surrender of the Joseon king, and Hwang Tae-gil accepted three bows and nine bows from the Joseon king Yi Liang on the high platform.

On 2 November, Li ordered all prefectures and counties to transport grain and goods from the treasury to Hanyang, and asked the prefecture and county officials to assist the Houjin army in collecting additional taxes. In addition, Li Liang also asked the concubines, princes, maharaja and two groups of relatives of Ganghwa Island to return to Hanyang.

However, this order was quickly rejected by Zu Dashou, who soon issued a proclamation in the name of the eldest concubine Han and Zhaoxian Shizi, stating that the Joseon king Yi Liang was now being held hostage by the Later Jin army, and all proclamations and orders issued in the name of Li Liang were invalid. Until the Houjin army left Korean territory, any peace treaty signed by anyone was null and void.

In addition, the proclamation also called on the people of all provinces to rise up against the Houjin army, and anyone who killed a Houjin soldier could be exempted from the slave and maid; Good citizens can get a reward of 20 yuan, and officials can get a reward for promotion.

The proclamation in the name of the concubine Han and the prince of Zhaoxian and the proclamation issued by Li Liang conflicted with each other, and some prefectures and counties, fearing the might of the Later Jin army, accepted Li Liang's orders. While other states and counties were unwilling to give in to the barbarians, they agreed with the announcement issued by the eldest concubine Han and Zhaoxian Shizi.

All of a sudden, numerous small battles broke out between the officials and civilians in the prefectures and counties of Korea and the Houjin rangers, and the arquebuses supplied by the Ming Dynasty to the Korean volunteers at a low price played an extremely effective role in such battles. Even the Later Kim general, Shumuru Yangul, was killed by the North Koreans with a musket.

The resistance of the Korean volunteers led to the Houjin army finally showing its brutal side, and began to loot and kill in the eight provinces of Korea, no longer caring about distinguishing between the two classes of nobles and commoners. This kind of spontaneous revenge can't even be stopped by Huang Taiji. However, the killing of the Houjin people finally strengthened the will of the Korean people to resist, and the casualties of the Houjin army began to increase day by day.

It was also at this time that Huang Taiji received the news that Yiju was defeated and Zhenglanqi was trapped in the city of Yizhou. This news made it impossible for Huang Taiji to wait for the Ming army to continue to be consumed in Hanyang, and he had to consider the withdrawal of the army. Because the Ming army mastered the concubine Han, Zhaoxian Shizi and others, Huang Taiji realized that Korea could not become a real subject of Houjin. So he simply acquiesced to the armies to plunder North Korea in order to replenish the vitality of Houjin, and he couldn't care about whether North Korea would tear up the alliance again in the future.
