Helasu, Mongolian-speaking elm tree.

Ulya Sutai was originally built by the Qing army general Fu Erdan fifty years ago. At that time, the situation faced by the Qing Dynasty was far inferior to that of now. Therefore, only elm trees were used as fences and soil was filled in between to cast a wooden city with a circumference of three miles.

After fighting with Truqin in Junggar, Guangzhou and Tianjin, they immediately realized that Truqin would be their number one enemy, so they gradually strengthened the construction of Ulya Sutai City.

To this day, through the efforts of previous generals, Ulya Sutai City has become a city that includes the former city of Fuldan as an inner city, and there is also a large city outside that is completely in the Central Plains style. It was built by the Han people from Shaanxi, Shanxi and the capital area of ​​the Qing Dynasty.

After completion, the outer city was 15 miles long and surrounded by moats. The city wall was tall and thick, three meters tall and ten meters thick. Except for the size of the capital, the solidity of the city wall was almost the same.

Ulya Sutai is the title of Mongolian nobles and Qing officials. For herders, they all call the inner city "Haila Sucheng".

Here, we have successively worked in the Kharulu Khanate, the Xueyantu Khanate, the Naiman Khanate, the Kerekhanate who moved westward, and the royal tent of the Ola Khanate is located in the western foot of Hanai Mountain. There is only one reason why it is favored by the Khanate of all dynasties.

There are mountains on both sides of the north and south. The Ulya Sutai River passes through the mountains. The valley is wide, suitable for garrisoning the army and can block the wind and cold in winter.

The Ulya Sutai River converges with the Zabukhan River here. The Ulya Sutai River is in the south and the Zabukhan River is in the north. The castle is located at the intersection of the two rivers. To the west, the south is the river water, and to the northeast is a mountain. Because the mountains here are closed, the temperature in winter is much lower than that in other places in Khalkha.

Therefore, the ice layer of the two rivers is not deep in winter, and it is only half a foot thick at the thickest time. It is okay for such ice populations to slowly come over, and the large army obviously cannot pass.

At that time, Fuerdan introduced the waters of the Ulyasutai River and Zabuhan River to the northeast, forming a moat, which made the castle surrounded by water. If the enemy wanted to touch it from Hangai Mountain, it would not work.

Such a large city obviously would not only be stationed in two thousand Manchu and Mongolian Eight Banners soldiers.

When the 50,000 civilians recruited by the Qing court completed the city, 10,000 people were exhausted and frozen to death. The remaining 40,000 people in the Qing court did not let them go back, but stayed in the local area!

With such a large population, it is obviously not enough to rely on the country to support it. However, due to the erosion of two rivers near Ulyasutai, the oasis area is also very large and the soil is quite fertile. The Qing court selected 4,000 young and strong people from the remaining 40,000 people, and first made them green camp soldiers.

Later, because I felt the importance of this place more and more, I carried all four thousand people to become part of the Zhenghuang Banner of the Han Army.

The remaining 36,000 people did not make him a slave, but became a civilian farmer directly under Ulya Sutai, allowing him to plant rye and alfalfa here.

All the support for the four thousand Han military flags was borne by these 36,000 people, and later the families of these 40,000 people were moved here, which finally stabilized them.

The arrival of so many people soon made the outer city lively. The Han people were smart and could also become craftsmen and small vendors while farming. This was what the Qing court was willing to see.

After the establishment of the Han army flag, the Qing court appointed Duan Feilong, the former top scholar of martial arts, as the deputy commander of the Ulya Sutai banner. In fact, it only governed the four thousand Han army flags. All of these four thousand Han army flags were infantry, and their main function was to protect the Ulya Sutai city.

Of course, since it is infantry, muskets and cannons, the Ulya Sutai City at this time is far from comparable to the Muzha City in history, which is only three miles in radius. It is not easy for ordinary people to take it down.

Duan Feilong was originally just an ordinary farmer near Jingji. Although he passed the martial arts top scorer, he was suddenly promoted to such a high position. He was obviously grateful and swearing to his loyalty. Not only did he come, but his younger brother, Duan Feihu, who passed the martial arts Jinshi in the same class as him, also came to guard Ulya Sutai City with him.

Since most of the outer city is Han people, the surrounding herders gave the city a nickname "Zitede City". In Khalkha, Zitede City is also called Buying and Selling City, but this one is the only one that officially named Zitede City.

Here is a joke.

Because the emperor of the Truqin Empire was called Qitade, the Qing court was very angry when they learned that the outer city of Ulya Sutai was called Qitade City by herdsmen. "This city is called Qitade City. Could it be prepared for Qitade?"

So he ordered that the name was strictly prohibited, but the herdsmen were used to calling it, and they had no idea how to investigate it. The officials had to turn a blind eye.

Hadan naturally knew these situations. Even if he wanted to attack Ulya Sutai, it was impossible. It was the flood season and the rivers were flooding. Not to mention the tall and sturdy Ulya Sutai outer city, it was not easy to cross two rivers smoothly.

What's more, according to the calculations of Baotai and others, I wish you a surprise attack. When you are crossing the river, the cavalry from all directions will give you a half-cross and attack you.

Nowadays, the camp in Baotai is still fifty miles away from Bayan. Once one side is dispatched, the other side can quickly detect and then react quickly.

The valleys on both sides of the Zabuhan River are wide, and there are rolling hills not far away, and there are ambush everywhere. It is almost impossible to fully investigate these places during the march.

Despite this, Hadan decided to launch a surprise attack.

He found Yan Dunhuang again.

In his mind, the combat power of the mountain brigade is not only stronger than that of ordinary reorganized divisions, but also above the guard division. What is even more rare is the ability of their horses, which is one of them in a thousand.

"General Yan, this is the case. The Qing army will definitely not be able to afford to lose this time, let alone the mature and steadfast leader of Baotai. They will definitely wait for us to start first. Once we move, they will not sit still and wait for death, but will also move."

"The nearby geographical structures are far more familiar than us. There are many places to use, so we have to guard against them"

"But we can't wait here forever. According to the latest information, the remaining troops of the Chahar Commander, some of the Inner Mongolia cavalry, Shanxi and the Green Camp soldiers from the Gyeonggi are rushing towards here, and they will arrive in at most one month."

"On the good side, Baotai's army came from the north of the Zabuhan River. They obviously wanted to get together and not give our army the chance to divide and annihilate it, but also gave us the opportunity to arrive at Ulya Sutai City from the south bank"

Yan Dunhuang smiled and said, "General, you don't want me to attack the city, that's completely impossible."

Hadan shook his head, "No, my plan is, it's not a problem to waste it just like this. There are two brigades north of the Zabuhan River that are enough to deal with Baotai's army. If your troops travel from Henan to Ulyasutai, whether they attack or not, they will have an impact on the Qing army."

"Once they move first, we have a chance"

Yan Dunhuang nodded, but he still had doubts.
