When Agu was gathering troops to prepare to advance eastward, the 20,000 cavalry led by Wu Haogu had already passed through western Liaoning and Liaodong. In late September of the second year of the Republic, it entered the border area between Goryeo and Great Zhou.

At this time, the boundary line between Goryeo and Dazhou was not on the Yalu River, but dozens of miles south of the Yalu River. The Khitans built two cities, Baozhou and Xuanzhou, on the south bank of the Yalu River, to monitor Goryeo.

These two cities fell into the hands of Ma Zhi after the Liaodong War. Later, Ma Zhi's territory was changed to Yanbian Prefecture, Bao and Xuan Prefectures also changed from prefecture to county, called Baoxuan County, and it is the bridgehead for Ma Zhi to enter Goryeo south and north.

When the cavalry led by Wu Haogu crossed the Yalu River and entered Baoxuan County, the small Bao and Xuan cities were in a tense and busy atmosphere. The docks beside the Yalu River were filled with cargo ships coming from Lushun. The shirtless Yanbian soldiers were busy unloading the ship.

Grain, arrowheads, winter clothes, feed, vehicles, horses, various equipment and tools... all kinds of unexpected materials were unloaded from the cargo ship like flowing water. The logistics aircraft of the Northern Goryeo Legion were transported to Bao and Xuan City by rough points. These two earthen cities have now become huge warehouses. The supplies required by the 53,000 troops marched from the North Road will be transported here by sea first. Then they are transported to various parts of the front line by mules, horses and chariots.

The governor of the Northern Goryeo Legion was located in Baocheng, in the original Baozhou Prefecture of the Liao Kingdom. The governor of the Northern Goryeo Legion was Ma Zhi, but his military talent was limited and he could not command the Zhou Army, which was becoming more and more complicated. Therefore, the Dujun Pilot Department formed a military commander for him with Luo Gang as the general military aircraft, which was actually responsible for the entire army's operations.

When Wu Haogu's cavalry crossed the Yalu River from the floating bridge, Luogang guarded the bridgehead on the south bank of the floating bridge to welcome him. Wu Haogu's son Wu Yiyong once again took a break from the Knights' Academy and was assigned to Luogang as a Jiyi. At this time, he was also in a tight military uniform and guarded by Luogang.

Seeing this 17 or 18-year-old son standing there proudly, the smile on Wu Haogu's face could not be concealed.

If the Battle of Goryeo goes well, the three years of the Republic, and at most four years of the Republic, this kid can complete all the Knights Academy studies. Then he should go to Kaifeng Prefecture to marry Zhao Ji's eldest daughter Zhao Yupan back... It's almost the same as the sixth year of the Republic, and he should be a grandfather, right?

Haha, I was only in my early forties at that time, so I became my grandfather... It was incredible to think about it!

Luogang stepped forward and saluted Wu Haogu: "Raogang, the general military aircraft of the Northern Goryeo Legion, met the Head of State!"

Of course, the etiquette of the Republic is different from that of the Song Dynasty. It is not popular to kowtow and bow, and military salutes are even simpler. Just stand at the right moment and raise your right arm.

Wu Haogu raised his right hand gently on the horse's back, and also gave a bow, and then asked, "Where is Ma Zhi?"

Luo Gang said: "Report to the Head of State, Governor Ma led his troops to Pyongyang."

"Go to Pyongyang?" Wu Haogu asked, "Go to fight Yin Yanchun?"

Luo Gang shook his head: "No, Yin Yanchun has given up on Pyongyang."

"Give up Pyongyang? Did he retreat to Hanyang?"

"Not that," Luo Gang replied, "I received a notice from the South Goryeo Legion yesterday, and the Goryeo people also gave up Hanyang City. General Ximen's governor's commander had already entered Hanyang City four days ago."

"Hanyang has also obtained it?" Wu Haogu nodded with a smile, "In this way, there is only one open city left."

At this time, Wu Haogu suddenly found Luo Gang's face was worried. So he asked, "What, do you think there are too few enemies that can be killed?"

Luogang shook his head and said, "The Head of State is joking. How could the subordinate officials think that there are too few enemies? It's just that the General Military Command believes that the Goryeo people are planning to fight for a protracted war of resistance."

A protracted war of resistance?

Why?

Wu Haogu frowned and said to Luogang: "Resist the enemy, this is not a place to speak, go to the governor's office to talk."

"Here!"

Luo Gang bowed, then waved to the followers in the distance, and soon someone moved two horses over. Luo Gang and Wu Yiyong each rode one, Luo Gang led the way, while Wu Yiyong and Wu Haogu walked with him.

The father and son talked about the battle of Goryeo in front of them on the way to Baocheng.

"Yi Yong, what do you think of the Battle of Goryeo?" Wu Haogu wanted to test his son's military level, so he took the initiative to raise the topic.

"Father, the child thinks the Battle of Goryeo will last for a long time."

Wu Yiyong's answer surprised Wu Haogu a little.

"How could it be?" Wu Haogu asked, "Our army dispatched 100,000 people to take more than 100 cannons, and the navy transported supplies from the water. What did the Koreans have? How could it last?"

"The Goryeo people have countless valley walls and hundreds of years of operation." Wu Yiyong analyzed, "On the flat ground along the West Sea coast, the Goryeo people are no match for us no matter what.

But the Koreans were not that stupid. They knew that they could not beat us, so they took the initiative to give up the flatter western coastal areas and retreated to the middle and east where mountains overlapped. This was the idea of ​​protractedness.

The terrain of Goryeo is mainly mountainous, and there are no large plains like Liaodong and Hebei. Even in the Sanjing area on the western coast, there are only small plains. If we don’t have the advantage of sea routes, it will not be that easy to fight from north to south.

Now, the western part of Goryeo, the Sanjing, and the Quanzhou area along the southwest coast of Goryeo should be captured soon. However, the remaining parts of Goryeo are not easy to capture!"

“Is it because it’s mountainous?”

"It's not entirely because of the mountains," said Wu Yiyong. "It's also because the Goryeo Kingdom has been united for hundreds of years, and there are many powerful people in the country, with walls everywhere, similar to the Later Han and Jin Dynasties. Even if our army can capture Yin Yanchun and destroy the court of Nan Goryeo, it's probably going to take several years to pacify thousands of walls."

It's really awesome!

After listening to Wu Yiyong's analysis, Wu Haogu also felt that this battle in Goryeo may not be as easy as he believed.

Because Goryeo is studying in the Song Dynasty, and has the imperial examinations, and claims to value culture and neglect military affairs. But in the bones, it is still the same as the two capitals of the Eastern Han Dynasty, which makes it a gentry, manor, tribe, and terrain with the valleys, which is particularly easy to have wall-dock-style separatist!

The royal power of the Goryeo court has always been only useful in the plains along the western coast. Going east, valleys of all sizes are under the control of prominent families and powerful people. Perhaps there are thousands of Biwu Mountain Village waiting for the Zhou army to break!

If the purpose of Zhou's troops was to support an obedient Goryeo court and not to violate the bottom line of these feudal tyrants in Goryeo, the war might be ended soon.

But this time Wu Haogu wanted to destroy the country! Goryeo is the weakest time now, and if it cannot be annexed, it will be even more difficult in the future.

"Yong'er, can you have a good plan to defeat the enemy?" Wu Haogu asked.

Wu Yiyong said: "There is no good strategy, only stupid battles. Fortunately, although the Goryeo Kingdom is mountainous, there is no natural danger. It is surrounded by water on all sides, so transportation is quite convenient. The army only needs to attack from Sanjing, Quanzhou, Luozhou, and Buzhou in the south, step by step and advance fortresses. After several years, it will be able to overcome all its achievements."

Step by step, the fortress is to advance... In fact, it is to use the fortress of Zhou's semi-feudal and semi-capitalist fortress to replace the fortress of Goryeo's borders!

Although time-consuming and labor-intensive, the effect is still very guaranteed.

"Is this your idea or the plan of the General Military Control Commission?" Wu Haogu asked with a smile.

"This is taught in the Knights Academy. I guess the General Military Command will use this method." Wu Yiyong smiled and replied, "If you occupy a territory, you have to build a fort and build a city, and spread our knights and soldiers out to suppress the dangerous land of the enemy country. Only in this way can you consolidate and last for a long time!"

Wu Haogu nodded. This is indeed the method! The republic he established himself is a semi-feudal and semi-capitalist approach, and capitalism mainly exists in big cities and overseas trade. In the vast rural areas, it can only rely on semi-feudal military citizens to rule.

And all kinds of fortresses are symbols of the rule of the Great Zhou Dynasty!

Of course, the era of fortresses was actually over for the Great Zhou Republic Army.

Because the Great Zhou Republic Army has entered the age of hot weapons! Although it is not equipped with muskets, bronze cannons have begun to be widely used.

In addition to the bastion, ordinary bastions are vulnerable to the Republican Army.

Therefore, the Battle of Goryeo is not difficult to fight, but it is time-consuming... It seems that Wu Haogu must stay in Goryeo for a while and deal with the issue of resettlement of knight households and military households. This time, he was to resettle military citizens in the real enemy country, which was a bit like Xia Jun and Yi people. So how to arrange it is just a knowledge.

Including the 30,000 households in Mazhi, Dazhou can place up to 50,000 military citizens on the Goryeo Peninsula. The standard for resettlement of 100 households and one dock can almost have 500 wall docks. So many wall docks cannot be placed on the western coast, which is meaningless. You have to deploy them eastward, push them layer by layer, and push them all to the west coast of Goryeo!

...

Just when Wu Haogu was planning to spend the winter on the Goryeo Peninsula, his old friend A Guda did something beyond everyone's expectations!

Aguda's 50,000 troops (the number of corrective soldiers) suddenly advanced eastward and appeared on the grassland west of the Swallow Fort, which was temporarily built with sandbags and rammed earth, located next to Yuanyanglu.

Fifty thousand soldiers, plus Ali Xi who was accompanying him, the total strength was nearly 100,000!

The Jurchens are invincible! Now there are 100,000, which is endless, covering the entire grassland. Why don’t you be frightened?

The Swallow Fort, which stood in front of these 100,000 Jin soldiers, was just a medium-sized fort built by pensions. There was also a large amount of forage and grain piled up in the prism, and the cured meat and dairy products. This fortress is not only a symbol of the Dazhou Kingdom's grassland on the dam, but also a front-line supply center. It is a sufficient supply supply for tens of thousands of troops to supply for several months. In addition, the area inside the fortress is not small, and it can completely garrison an entire cavalry division!

However, the only ones stationed in it are Wang Yan, two infantry battalions and one artillery battalion commanded by Li Xiaozhong, with a total force of only more than 2,000 people...
