Zhu Yunwen to build Suiyuan City is the Hohhot City of later generations, Mongolian Altan Khan in the southern foot of Daqing Mountain modeled on the model of Yuan Dadu to build a city, the Ming Dynasty gave the name of Naturalization City, after the Qianlong period in the northeast of the city built Suiyuan City, as the military camp of the garrison of the Eight Banners, the two cities are collectively called Guisui. The later General Fu Zuoyi went down in history as the chairman of Suiyuan Province and the victory of Bailing Temple.

The location of Suiyuan City is unique, the north is Daqing Mountain, the southeast is Manhan Mountain, between the two mountains form a valley, the climate is humid, the water and grass are abundant. The largest river in the territory is the Dahei River, which flows into the Yellow River from east to west through the vicinity of the Dongsheng Acropolis; The second is the Xiaohei River, which is a tributary of the Dahei River, formed by the merger of two rivers, and is later called the West River (Zadagai River) and the East River (the collective name of Halaqin Valley to the Xiaohei River); There are also rivers such as the Qingshui River in the territory. So it can be said that this is the most environmentally friendly area north of the Great Wall, suitable for grazing, but also suitable for farming.

Xu Huizu's Chinese military tent was set up at the junction of the East River and the West River, that is, on the bank of the Xiaohei River, and to the north of it was the Suiyuan City under construction. Although it was the middle of winter, the soldiers and civilians of the Ming Dynasty were accustomed to building cities at this time, because this was the weakest time for the Mongols, and most of the herdsmen hid in the leeward tents and waited for the winter to pass, and it was impossible for the army to be summoned temporarily.

At this time, in the big tent of the Chinese army, Xu Huizu, Ping'an, Wang Du, Song Sheng and Qu Neng were holding a military meeting, Song Sheng came from Baidao City, and Qu Neng rushed from Datong with a fast horse, and it took three days to quickly whip the horse on the road, so it seemed to be full of dust, but the spirit was not bad, and he was speaking at this time: "General Zhengbei, the last general came this time mainly to report the situation in Datong, and to coordinate the operations of the two armies of Suiyuan and Datong." ”

Xu Huizu clenched his fists and said, "General Qu has worked hard, what is the situation in Datong?" ”

"General Mo and General Chen Zhen arrived in Datong at the end of October and quickly took over the defense of Datong. According to the report that the night was not collected, at the beginning of October, almost at the same time as the Mongolian cavalry appeared in Suiyuan, the Mongolian cavalry was also found outside the fortresses outside Datong, such as Maoerzhuang, Xinghe, and Tucheng. The last general personally led the troops out of the fortress to reconnoitre, found that the Mongolian cavalry is not much, was discovered by our army will flee immediately, the last general sent out the night not to collect, to reconnoiter the enemy's situation, according to the preliminary report, in the vicinity of Jining, there are about more than 10,000 cavalry, at present its intentions are unknown. ”

Xu Huizu glanced at Wang Du and said, "The situation on our side, let Zizhong introduce it." ”

"Okay." Wang Du stood up, walked to the map, and said: "At present, our army has occupied Baidaoling and started to build Baidao City, and the two generals Song Sheng and Song Xuan are responsible for the defense. ”

"General Ping'an is currently leading the cavalry to be responsible for the security of our army's left flank, the defenders of the barrier along the Yellow River have all been mobilized, and the rangers have been arranged in Gaoquesai, if the Mongolian army enters the Hetao steppe from Gaoque, our army can respond in time, and can fight a decisive battle with the Mongolian army along the Dahei River and Xiaohei River, but this possibility is not very likely. Although this steppe is vast, it is slightly narrow for the cavalry, and the chances of winning a decisive battle between the Mongol army and our army are not high. ”

"For the right wing, the east of this area is called Gray Tengliang, the terrain is higher, it is a high mountain summer resort, Hongwu had set up the official mountain guard in the early years, but due to the cold of the high mountains, the supply is difficult, has been removed. Back then, Liaoxing Sect Yelu Zong Zhen once gathered a large army here to prepare to attack Western Xia, so it was necessary to guard against it. ”

Qu Neng thought for a while, turned to Ping'an and said, "General Ping, can you tell me about the battle of Baidaoling?" ”

"Yes," Ping'an also walked to the map and said, "That day, General Song Xuan and I arrived near Baidao and encountered more than 10,000 Mongolian cavalry, and after a fierce battle, our army lost more than 300 people, and the Mongolian army lost more than 1,000 people. After that, we interrogated the captives, these Mongols belonged to the Asurt tribe, from the far west, Yuan Wuzong used to be a Praetorian Guard, and the leader of the army that day was their leader Arutai, who was currently nomadic near the Krulun River, this time at the behest of the great leader of Warat, Ugqi, who sent them 5,000 sets of armor. ”

"Ugqi?"

Song Sheng said: "General Qu, Ugqi is the great leader of Warat, a nomadic tribe west of the desert, and now it is very powerful, and the nomadic land extends from the southern foot of the Tianshan Mountains to Lake Baikal. As he spoke, Song Sheng made a gesture on the map: "At present, Warat is divided into four divisions, and the total number of cavalry should be more than 100,000, and the headquarters of Ugqi is near the West Sea, west of Jiayuguan." ”

Qu Neng frowned and said, "This Ugqi is a little crazy, he came from so far away, and it's winter, what do you want to do?" ”

Xu Huizu looked at Song Sheng, Ping'an and Wang Du, and said, "General Qu, before you came, several of us discussed it, and thought that there must be a hidden story behind Ugqi's dispatch of troops this time, unless he wants to be the Great Khan of Mongolia, the construction of Suiyuan City will have no impact on him." But he is not a member of the Golden Family, and it is almost impossible to be a Great Khan. ”

"And what is he for?"

Xu Huizu shook his head and said: "Although we don't know his true intentions, but according to the edict of the imperial court, Suiyuan and Datong take a defensive position, at present, General Song Sheng has blocked the white road, and General Ping'an has also been full of scouts on the western front, but the east needs General Qu to cooperate, and our army is a horn, if the enemy is found to be attacking our army from Gray Tengliang, I hope that General Qu can send reinforcements to the west in time." Gathering the strength of the two armies, on the grassland at the southern foot of Yinshan Mountain, it is not a problem to defeat the Mongols. ”

Qu Neng made a gesture on the map and said: "Dongshengwei can't be mobilized, and the Yellow River crossing must be guarded, and the three guards of Yunnei, Zhenyu, and Yunchuan should be able to arrive in time, but there are a lot of deserters from these three guards, and the total number of cavalry that can be mobilized may not exceed five thousand." Datong has 30,000 cavalry, and at most 20,000 can be dispatched, and you can arrive in four days day and night, and you need to hold out for four days. ”

Ping'an said: "Can you arrive in four days?" ”

"There should be no problem, I led a thousand cavalry this time, and it took me four days to rush over, but I only marched during the day. In that year, Emperor Taiwu of the Northern Wei Dynasty Tuoba Tao attacked Rouran from Pingcheng to Elechuan, and it only took three days and two nights, so four days was enough. ”

Everyone glanced at each other, and Xu Huizu clapped his hand and said: "This is very good, it is decided like this, General Qu, Suiyuan and Datong will inform each other of the military situation every day, and if there is an abnormal situation, please also ask General Qu to support." ”

"Okay, no problem."

At this time, Wang Du suddenly said: "General Qu, what will happen if the enemy army suddenly attacks Datong?" ”

Qu Neng said with a smile: "Datong City is high and deep, and there are more than 100,000 garrisons, so there will be no problem." ”

"Well, there will be no problem with Datong, so will the Mongol army attack Xuanfu, Kaiping, and Daning?"

"I'm afraid this won't work, there are King Gu, King Yan, King Ning...... over there" Speaking of this, Qu Neng suddenly stopped, glanced at everyone, and said, "This...... Now that King Yan is seriously ill in Beijing, King Ning is in charge, maybe ......"

Speaking of this, Qu Neng glanced at everyone and didn't continue, but everyone understood what he meant, because King Yan was seriously ill and not in Beiping, then Beiping might become a weak point, can Li Jinglong, who is in charge of Beiping, compare to King Yan? Or can King Ning carry the burden? It's a pity that these two people are high-ranking and powerful princes and princes who are deeply trusted by the emperor, so everyone doesn't dare to continue.
