"Has the domestic city been captured?"

"Back to the king, yes, the domestic city of Goguryeo is located on the plain. It is more convenient for our army to mobilize its troops and transport artillery, so it was captured on schedule."

"Okay, I know."

The follower left, Yuwen Weihan looked at the battle report, put it on the case, and then looked at the map.

The roar in my ears was endless, and it sounded a little noisy, but there was no way. He was on the steamer ship at this moment, and the disadvantage of the steamer ship was that it was noisy, but the army had to go upstream, so it was most convenient to ride a steamer ship, saving time and effort.

Yuwen Weihan looked at the location of the domestic city of Goguryeo on the map, and then looked at the Yalu River in the southeast of the southeast, and was quite happy.

It is now March. Because the ice period along the coast of Liaodong was longer than in previous years, the troops gathered in Yanjin, Youzhou and Huangcheng, Laizhou, have only floated to the sea to fight and marched towards the battlefield.

The first batch of attacking troops had successfully completed the scheduled plan. In the early spring, they used steamships and ships to transport troops and artillery, and quickly conquered several important Goguryeo cities in the Yalu Water Basin with lightning speed, and domestic cities were one of them.

The domestic city was once the capital of Goguryeo for hundreds of years. Because the city site is located in a plain surrounded by mountains, it was named Pyongyang at that time.

In the late Later Han Dynasty, when the Gongsun family, which was entrenched in Liaodong, fought against Goguryeo, the Gongsun army once captured the capital of Goguryeo.

Later, Goguryeo expanded to the area south of Yalu River, and its territory crossed the Yalu River, then crossed the Sasu River, and then crossed the Yu River, constantly swallowing Baekje and Silla territory. So Goguryeo moved its capital to Xindu on the north bank of the Yu River, which was named Pyongyang, and the capital Pyongyang was renamed the domestic city.

In the past, between the Hei Water, a small country in the southern border of Fuyu Kingdom was able to gain its current territory through continuous expansion. Its shape looked like a chicken leg. The large piece of chicken leg meat was from Liaodong and Fuyu, and the chicken leg bone was the peninsula (the upper half).

Yalu Water is like a knife that can cut the chicken leg meat and chicken leg bones. Zhou army marched along the Yalu Water, which can penetrate most of the land of Goguryeo, making it difficult to check its head and tail, and the north and south armies are difficult to respond.

To do this, it is not enough to control the downstream areas of Yalu Water. At least you have to take down the northern coast of Yalu Water, the Goguryeo Fortress Group with the domestic city as the core. The domestic city is one of the three capitals of Goguryeo today.

Therefore, it is the key to capture the domestic city as soon as possible, and then rely on this to conquer the surrounding cities, control the northern bank of the river section in the Yalu River, and cut off the main channels for north-south communication.

Now that the first phase of the offensive target is taken, we should next step along the Yalu Water line, set up fortresses along the coast, use artillery to protect the base, transport soldiers and supplies through water to maintain these fortresses.

Ensure the Yalu Water Defense Line and be able to block the attack of the Goguryeo army at the north and south ends at the same time.

However, even if the Zhou army controlled the Yalu Water, the downstream areas could not really "cut the Goguryeo border in half", because the upper reaches of the Yalu Water were full of mountains, and the small army of Goguryeo could still travel north and south through mountain roads among the mountains.

Even so, it is impossible to mobilize large-scale troops. Even if people can walk on mountain roads, the convoys of transporting grain cannot leave.

This is the effect Yuwen Weihan wants to achieve. The enemy's loss of one's own will be a good opportunity to take advantage of the situation.

Now, the main force led by Yuwen Weihan is not investing in Liaodong warfare, nor is it going directly to Pyongyang, the capital of Goguryeo. Because the other party suffered a great loss, it must have set up close defenses in the area of ​​Wushui.

Even if the situation is wrong, the monarch and ministers of Goguryeo would lead their main army to the north, which is the domestic city of the old capital, and rely on the continuous mountains and a large number of mountain cities to confront the Zhou army, and confront them until winter.

Therefore, we need to first control the Yalu River coastal areas and cut off the way for the monarch and ministers of Goguryeo to escape north.

During this period, the Goguryeo army guarding Pyongyang was deceived by the Zhou navy, who was circulating at the mouth of the sea by the Zhou navy, who dared not go north easily because they wanted to prevent the Zhou army from approaching Pyongyang along the waters.

As for the Goguryeo army in Liaodong, it would be restrained by the Zhou army's partial divisions based on Liaokou. The hundreds of thousands of troops (known as) that Goguryeo pieced together in Liaodong were nailed to Liaodong and dared not go south easily.

This is the combat plan of this Eastern Expedition. The east and west wings were feinted to restrain them, and the middle army led by Yuwen Weihan himself wanted to open up the situation from the Yalushui line.

Now that the war has a good start, Yuwen Weihan is naturally happy.

He walked out of the cabin and looked at the fleet of steamships that stretched for miles, and looked at the rolling smoke above the fleet. Not only did he not feel the thick smoke was too bad, but he felt relieved after watching it.

For the Zhou State, the use of troops along the Yalu River coast was against the current. Even if the troops could go on land, the transportation of food and grass must be carried out through water to be safe and transportation efficiency is high.

If you want to sail against the current, you will invest a lot of manpower and consume a lot of money.

During the high water season, the water flows rapidly, and ships loaded with food and supplies rely on sails to travel together, so they can only walk 20 or 30 miles a day, which requires a large number of paddlers to take turns rowing, and even in some river sections, the boatman needs to pull boats on the shore.

In recent years, the government troops have used troops upstream along the Yalu Water, relying on investing a lot of manpower to achieve water transportation of food, grass, personnel and materials. If it is just a harassing attack, it doesn't matter, but it is necessary to maintain a defense line along the river and ship against the current, which consumes a lot of money.

In the face of the Zhou Dynasty's years of harassment and attacks, Goguryeo implemented the tactic of strengthening the walls and clearing the fields. Therefore, the food and grass consumed by the Zhou army basically depend on the rear to transport. The soldiers on the front line had to consume food, and the young and strong people involved in the transportation also had to consume food.

The more people participate in the transportation, the greater the consumption of food during the transportation, and the less food will be transported to the front line. This is an unsolvable problem until the emergence of the steamship.

Steamers do not consume food, only burn coal, can travel 150 miles a day on the river, sailing against the current on the Yalu Water, and the daily distance will not be lower than this number. Except for the crew members who have to eat, the consumption of grain during transportation is almost no.

With this magical ship, the Zhou army no longer took time and effort to use troops along the Yalu Water. They could invest more troops and set up defenses along the Yalu Water coast, forming defense lines between the forts and villages to block the north and south.

However, controlling the Yalu Water cannot really "cut the border of Goguryeo in half", because the upper reaches of the Yalu Water are stretching mountains, and the small army of Goguryeo can still travel north and south through mountain roads among the mountains.

Even so, it is impossible to mobilize large-scale troops. Even if people can walk on mountain roads, the convoys of transporting grain cannot leave.

Therefore, controlling the middle and lower reaches of Yalu Water is like pinching a person's throat with one hand. Although the other party will not die, it will definitely not feel good.

Yuwen Weihan thought so, looking at the river view along the Yalu River, full of confidence. In front of the river, there was the river where Wugu Water entered Yalu River. On the mountain to the north of the river, there was the Bozhuo City of Goguryeo.

Now, Bozhuo City has changed its owner, and the same is true for Wugu City upstream of Wugu Water.

More than a month has passed since the Zhou army captured Bozhuo City. Now the Hezhou in Bozhuo City has become a huge transport port. Tens of thousands of soldiers and civilians are busy here, providing strong support for the subsequent actions of the Eastern Expedition Army.

Yuwen Weihan looked at the transport terminal and looked at the south bank of Yalushui, and looked at the already large-scale Luzhai on the shore, very satisfied.

Although the cross-sea telegram line connecting Lushun and Huangcheng has not been connected until now, and although the extended ice period in the coastal areas has led to the delay of the large-scale attack time, everything went smoothly in this battle as planned.
