Uiju, a Korean town across the river from Zhenjiang (Dandong), as long as Uiju is captured, it will be able to open up the communication line between Korea and Liaodong, and put Liaodong's manpower and materials into the Korean battlefield.

The second battalion of the Liaodong Army and the first battalion of the cavalry rushed to Yizhou on the same day, and there were very few Qing defenders in the city of Yizhou, only more than 1,000 Han soldiers, and the city of Yizhou fell quickly under the attack of the second battalion carrying 125 mm siege guns.

After conquering Yizhou, the second battalion immediately signaled to the warships on the river, located in the Liaodong staff headquarters in Zhenjiang, Liu Heng received a report and said: "Since Yizhou has been conquered, let people erect a pontoon bridge immediately." ”

"Yes."

The General Staff quickly conveyed the order, and when the plan for landing in Korea was being developed, the General Staff had already ordered the materials below to be prepared for the erection of the pontoon bridge.

During this period, Liaodong collected more than 100 small boats and many small sampans and other floating objects, and as soon as the order of the General Staff Department was given, the engineers on standby immediately began to erect pontoon bridges on the Yalu River.

Liu Heng and a cadre of the Liaodong Operational Staff Department came to the bank of the Yalu River, watching the busy sappers erecting the pontoon bridge in an orderly manner, Liu Heng asked: "When can the pontoon bridge be erected?" ”

"Back to the Chief of Staff, two more hours will be fine." The company commander of the engineer company replied.

Liu Heng nodded with satisfaction and said with emotion: "This is war, professional war." ”

"If our lord does not completely professionalize the war, we will not be able to enter a no-man's land in Liaodong, the Manchu Qing is now vulnerable, but our cavalry is not much, we can't use cavalry to fight a decisive battle with the Qing army, if there are enough cavalry, we can sweep Liaodong like a storm, and chase the Qing army in Korea like a lost dog, and I can't end up in panic." Liu Heng said regretfully, and everyone couldn't help nodding.

"There are still 8,000 cavalry in the new battalion being trained, and it is estimated that it will be put into the battlefield in a few months, and it will be much easier to fight when the time comes." said the deputy chief of staff.

On the riverbank, more than 20,000 third-line troops have already completed their assembly, and after the pontoon bridge is erected, they will cross the river and enter North Korea.

"How is the training of the third-line troops?" Liu Heng asked others.

"There is no problem in discipline, there is an inspection team in the third-line army, and a Shandong veteran is placed in every ten people, which is enough to calm the scene, as long as you don't fight a tough battle, there will be no problems."

"In addition, most of them will also use artillery, so it is not a big problem for them to fire artillery on the city wall, but the clearance value is very high, but when facing the Qing army attacking the city, it is no problem to hit."

"That's fine."

…… On the same day, the two pontoon bridges were quickly completed under the erection of the engineer barracks, each of which was more than two meters wide, and was paved with boats and sampans underneath, and a layer of flat wooden planks on top of them, so that vehicles could pass on the pontoons.

The 20,000 third-line troops who had been trained quickly passed the pontoon bridge and entered the city of Uiju. After the passage of the third-line troops, the prepared supplies and administrative personnel also entered the DPRK through the pontoon bridge one after another.

After the administrative personnel arrived in Uiju, they immediately imposed a curfew on Uiju and sent men and horses to clear the walls and fields, and at the same time began to rectify the city defense of Uiju City.

There are specially trained personnel for planning in the city defense, these people are proficient in all aspects of the city defense, can see where the loopholes of a city are, which point of defense needs to be strengthened, and can better cope with various siege methods, whether it is attached to the ant siege, or digging tunnels, or deceitful cities, internal response and other means.

When building a city defense system, if there is a shortage of materials, they should be collected from the local area first, and if they are still lacking, they will be reported to their superiors, and then they will be delivered from the rear.

The second battalion of the cavalry of the Liaodong Army is a team specially responsible for escorting transportation.

On the Korean battlefield, everything is based on stability.

The solar term at the beginning of April has entered the early summer, the sun seems to be very warm and warm, and the rainy spring has passed, which is a very suitable season for combat.

The 1st Battalion of the Liaodong Army, under the cover of the 2nd Cavalry Battalion of the Shandong Army, took Pyongyang from Tieshan Mountain, the capital of North Korea, which was still under the control of the Qing army.

At the same time, the second capital of North Korea, Namsan Fortress (Seoul), was also under the control of the Qing army.

However, the first battalion of the Liaodong Army was on the way to advance, and the corpses of Koreans were everywhere, and the Qing army slaughtered the cities of Xuanzhou and Dingzhou along the way.

However, such an act was only futility of madness, because the first battalion had enough supplies and used horse-drawn carts to transport grain, and compared with the mountainous terrain in the east, the terrain in the west was mainly plains and hills, and there was not much need for people to transport grain.

The terrain of Korea is full of mountains in the east, except for a relatively flat section of the coastal area in the east, and most of this area has been built in the last year, and there are no people in it, and if the Qing army penetrates there, it will not stay long.

The 2nd Battalion also began to advance southward, albeit in west-central Korea, taking control of towns along the way.

They advanced well, and in cities not occupied by the Qing army, the Koreans would immediately open the gates to the Ming army, because they were the king's division.

North Korea has been a barrier of the Ming Dynasty for many years, and the North Koreans have a strong ability to accept the Ming Dynasty. Koreans still used Chinese characters in this era, and they also used Han Chinese clothing.

The two battalions basically maintained a speed of 80 miles to advance, and after counting the stagnation time caused by some unexpected circumstances, they could basically advance to the southernmost point of Korea in nearly a month and a half.

North Korea's 3,000 miles of rivers and mountains are gradually falling into the hands of Zhao Yan.

North Korea is not as barren as people think, but South Korea is barren, and North Korea is rich in mineral and water resources.

For example, the Maoshan Iron Mine, which is a world-class open-pit iron mine, is very easy to mine, with an annual output of 6 million tons, and the reserves of magnesite are ranked first in the world.

North Korea has one of the highest per capita mineral resources in the world, and during the occupation of Korea, North Korea was more developed than South Korea. South Korea's resources are much poorer, but it is normal for the stick to develop quickly with the technical support of the Americans.

Zhao Yan's invasion of Korea this time was to restore the territory of the Tang Dynasty and even occupy the whole of Korea. By the time of the Tang Dynasty, China had taken control of the Han River, which was basically the entire territory of North Korea in later generations.

Therefore, the occupation of North Korea is a legitimate thing, and it is not a problem to occupy South Korea if it is more aggressive and thicker, but the North Koreans are not easy to deal with.

After all, Korea is a barrier of China, and most of the culture of the Koreans uses China, and there is no cultural conflict, if the whole of Korea is occupied, it is estimated that it will not look good in the history books in the future, and there must be an excuse, otherwise it will damage the demeanor of the Celestial Empire.

When you don't have the strength, you naturally can't think of yourself as the Celestial Empire, but in this era, Daming is indeed the Celestial Empire, and Zhao Yan also has enough time for Daming to maintain this status.

At the same time, the demeanor of the Heavenly Empire must also change, and it cannot be as tolerant and unremunerative as before.

…… Hwang Tae-gil retreated all the way to Pyongyang, but in Pyongyang he did not commit any massacres and did not rob, but forced the people to blow down and raze the city walls with gunpowder.

Yue Tuo asked puzzledly: "Your Majesty, why do we want to raze the city wall?" ”

"We will inevitably have to stay in North Korea for a period of time in the future, and we must have enough supplies to survive, so we must tear down the city wall so that we can grab food and grass from Zhao Yan." Huang Taiji said.

"Then don't you take away the food from the North Korean family?" Yue Tuo continued to ask.

"It's like raising sheep, if you don't give the sheep grass to eat, will the sheep grow meat for you to eat?" Huang Taiji said, Yue Tuo still didn't understand and asked, "That's not cheap Minggou for nothing." ”

"If they rob these North Koreans of their food, then they will lose the hearts and minds of the people in North Korea, so they will definitely not rob them."

"Your Majesty." Yue Tuo exclaimed convincingly.

"We must tear down all the walls of the rich land of Korea before the Ming army comes." Hwang Tae-gil said, "Divide the soldiers and horses into ten units, 3,000 people each, and move separately in North Korea. ”

"Yes." Yue Tuo commanded.

The Qing army soon divided into ten groups and began to sweep south of Pyongyang, taking cities one by one, then robbing the treasury of grain, and then forcibly asking the Korean people to tear down the walls. This is also the strategy that Hwang Tae-gil thought of not long ago, they are trapped in North Korea, and the biggest problem is actually supply.

Under the pursuit of the Ming army, those heavy siege equipment must be abandoned, and once those weapons are abandoned, there will not be much food to be grabbed in Korea.

Just when the Qing army was dispatched everywhere, the scouts of the Ming army were also dispatched. I saw that whenever these scouts went, they posted the news of the defeat of the Qing army in Liaodong, and also attached an edict issued by Duoduo when he ascended the throne, and a surrender notice.

In the surrender notice, it was promised that all surrendered personnel would be treated preferentially, and Niu Lu would really lead people to surrender, seal thousands of households, and reward 2,000 taels of silver; Jia La's real lead people to surrender to sincerity, seal the general, and reward 5,000 taels of silver; Gushan Ezhen led people to surrender, sealed the general soldiers, and rewarded 50,000 taels of silver; Melle really led people to surrender, sealed the deputy chief soldier, and rewarded 30,000 taels of silver.

The soldiers of the Eight Banners surrendered to sincerity, rewarded with twenty taels of silver, and were given preferential treatment.

It just so happened that Huang Taiji scattered 30,000 troops, and for a time all the Qing troops learned about the situation in Liaodong, and the Qing army was in an uproar.

When Huang Taiji received the news, he didn't believe it at first, thinking it was a trick of the Ming army, but then dozens of Qing soldiers on horseback came from the north.

These Qing soldiers were not in good armor, like lost dogs, they were Qing soldiers who had just been released by the Ming army, and these prisoners were captured in Liaodong.

These Qing soldiers found Huang Taiji's soldiers and horses, and ran to take refuge, and for a while, they had the proof of these people, and the news made the Qing soldiers more convinced.

When Huang Taiji learned about it, he vomited blood several times with a 'wow', and fainted again.

"Prince Su and Ama were both killed in battle, and Duoduo, a rebel and thief, is so disregarded for the overall situation, hateful! Hateful! Yue Tuo was prostrate and crying, his hands kept rubbing the ground, and Yue Tuo's death made Yue Tuo extremely sad and angry, only to see him gritted his teeth and said: "Damn Ming dog, he said that I will slaughter all the men of his clan." ”
