In the first three years of the Western Han Dynasty (3 AD), Goguryeo moved its capital to the "domestic city" and built "Weinayan Fortress" as its acropolis, as the military garrison city of the domestic city, and the domestic city was interdependent and the capital city was each other.

In the third year of Jian'an (198), the 10th king of Goguryeo, King Sanshang, expanded the fortress and renamed the fortress as Maruduseong.

Marudu City is only five miles away from the domestic city, and is located on the north bank of the Tonggou River in the north of the domestic city. The city is high in the north and low in the south, the city wall on the east, west and north sides is surrounded by a steep cliff outside, and the relatively gentle slope is held inside, and the plane is an irregular quadrilateral, shaped like a dustpan. The circumference of the city is 6,395 meters, there are 6 city gates, and there is an urn gate at the mouth of the valley on the south side, which can be described as extremely dangerous.

Wang Hu led his army all the way through the cities that were voluntarily abandoned by the Goguryeo rebels, and arrived at the Marudu City in two days. ”

The two walls inside and outside the castle are all built with rectangular stones or square stone strips. The lower part is built in a stepped shape, and the layers are adducted layer by layer. Horse faces are constructed at intervals, and corner towers are provided at the four corners. It can only be attacked in the south of the valley plain.

The Goguryeo people were not stupid, and when they built the capital of Maru, they built an urn gate at the mouth of the valley on the south side, so that the enemy wanted to break through the capital from the south gate, which was quite difficult.

Su Mingxiu chuckled and said: "In fact, if you want to break through a mountain city like Marudu, the best way is to besiege it, and the grain and grass in the city will support it for half a year at most, and it will not be attacked after half a year." ”

"The siege itself is a stupid way to do nothing, and anything can happen over time. Don't besiege the city, but be delayed and lose the fighter plane, and defeat yourself. Liang Chengye said with a sarcastic look on his face.

Su Mingxiu smiled indifferently: "It's just a casual talk, why should General Liang care, even if we want to besiege the city, His Royal Highness won't give us a chance." ”

Wang Hu's brows furrowed into Chuan, he was only a five-grade Yanwangfu pawn army, before he became a pawn army, he was just a soldier who obeyed orders on the battlefield, and he relied on his bravery to kill the enemy's head on the battlefield before he was promoted to the position of the pawn army.

Now that His Royal Highness has appreciated him as the commander of the first army, Wang Hu, who can only fight on the battlefield, even if he is forced by Li Yu to practice the military book and learn the ability of the commander to command the battle, it is difficult to change his nature after all. A city like Marudu, which has sufficient troops and dangerous terrain, finally blinded Wang Hu, and in impatience, he ordered the whole army to build a camp to rest and attack the city tomorrow.

The Southern Route Army led by Li Shangdan had only one Weiyuan City blocking its way along the way, and it was taken in less than an hour. Dozens of miles away is the domestic city, which won the battle, and the domestic city ordered the whole army to rest in Weiyuan City for two days in the pride of being in the bag.

Two days later, it took nearly two days on the way to lead the army to the domestic city, and in vain lost an opportunity to take advantage of the victory to pursue and attack Gao Yanwu by surprise.

In the past four days, Gao Yanwu calmly transferred the defenders of each city back to defend the country and the two cities of Marudu, so that the original defenders of the two cities were only more than 10,000, but now they have become a full 30,000 army and are waiting for the arrival of the Tang army.

After all, Li Shangdan rushed to the domestic city one day earlier than Wang Hu, and set up camp on the south bank of the Tonggou River in the southwest of the domestic city, at the foot of Qixing Mountain, and confronted the north and south of the domestic city, and could also contact Wang Hu, who was camping in the east of the river valley east of the city of Marudu, through the Tonggou River.

The battle plan was arranged by Li Yu as early as before the expedition, and the two armies converged in the domestic city, with Li Shangdan as the chief commander and Wang Hu as the deputy. Li Shangdan's troops attacked the inner city, and Wang Hu's troops attacked the pill capital, so that the two cities could not support each other, and if one of the cities was broken, the whole army was commanded by Li Shangdan to besiege the remaining city.

After Wang Hu led the army to arrive, he went to Li Shangdan's camp to meet with the commander on the same day to discuss the siege.

In the early morning of the second day, the two armies launched an attack at the same time, and for a time the war drums and thunder in the river valleys on the east and west sides of Yushan Mountain shook the sky.

Compared with the topography of Marudu City, the topography of the domestic city is undoubtedly much worse, and the whole city is built on the Tonggou River Valley Plain formed by the confluence of the Yalu Water and the Tonggou River on the south side of Yushan.

It is now summer, and the water level of both the Tonggou River and the Yalu River has increased significantly, and the river surface has widened.

When Li Shangdan discovered the attack, he discovered that it was an unfavorable move to build a camp on the south bank of the Tonggou River. To attack the domestic city, you have to cross the river first, but Gao Yanwu on the opposite side is not a vegetarian, if he is attacked by his half-crossing when crossing the river, the defeat in the first battle can seriously affect the morale of the army.

With a worried face, Li Shangdan wondered if he would not attack the city first, but instead build a camp in the east of the city and place the main force there, so that it would be convenient to go out of the camp and attack the city, and it could also cut off the enemy's northward escape route and block the reinforcements coming from the north.

Liu Tao, the general of the Broken Army, ran over with joy to tell a good news: "General, the northwest is in Yushan and Qixing Mountain, the nearest section of the Tonggou River is extremely narrow, just cut 18 zhang long trees to the banks of the river is a simple bridge, as long as you put up a few hundred big trees, the bridge is absolutely strong, and the surrounding mountains are full of 18 long trees. ”

Li Shangdan was overjoyed, patted Liu Tao on the shoulder and praised: "Hahaha! Liu Dayun immediately led the army to cut down wood and build a bridge, and I will give you the first credit after the bridge is completed. ”

"No!" Liu Tao called his subordinates with high morale and a group of sergeants to go to Qixing Mountain to cut wood.

Just find 18 zhang long logs, shave off the branches and drag them to the south bank of the Tonggou River, and a dozen sergeants will stand up and put the big trees down on the other side of the river. In just a few hours, the 3,000-strong army cut down hundreds of large logs to build a simple bridge, spread the branches horizontally on the rolling wooden bridge, and fastened the large logs with ropes, and the bridge was completed.

Li Shangdan waved the command flag, and the White Tiger Guard took the lead in quickly forming a military formation on the other side of the river, with crossbowmen in front and archers in the back aiming at the enemy troops who were galloping in the distance.

Gao Yanwu saw that the Tang army was building a camp on the south bank of the Tonggou River, so he started to take the Tang army to cross the river and send cavalry to attack half-crossing.

The Tang army erected a bridge in the narrow part of the river, and Gao Yanwu was in a hurry, and rushed out of the domestic city with 3,000 cavalry and went straight to the Tang army that was crossing the river.

Xie Qian, the former guard of the Yanwang Mansion, is now the captain of the White Tiger Guard, and the crossbowmen of the White Tiger Guard, who commanded the crossing of the river in an orderly manner, lined up in an array, looking at him with a murderous look with cold eyes

Li Shangdan led the first army of Baihuwei and broke the capture, and the second army of Dangdi set out from Bozhuo City to attack the domestic city along the Yalu River, and the two armies of Wang Husuo and Dingman and Tianshi set out from Cangyan to attack the cities in the west of the domestic city, and listened to Li Shangdan's dispatch under the domestic city. This king led the Yanyun Iron Cavalry, the Beihai Iron Cavalry Left Guard, the Qinglong, the Vermilion Bird Guard, and the Chaos Three Guards, and the four armies of Pingyi, Zhendong, Flying Tiger, and Jiaolong were stationed in Bozhuo City.
