According to the previous recommendation of Pharmacist Li, he appointed the commander of the Six Roads to attack the Turks, from west to east:

Li Daozong, the governor of Lingzhou, was the head of the Datongdao march

Chai Shao, the general of Zuo Wuwei, was the head of the Jinhe Road march

Li Yaoshi, the secretary of the military department, was the general manager of the march of Dingxiang Road

Li Shiji, the governor of the prefecture, was the head of the march of the Tongmo Road

Youzhou Governor Wei Xiaojie is the head of the march of Heng'an Road

Xue Wanshu, the governor of Yingzhou, was the head of the Changwudao march

Among the six armies, Li Daozong's Datongdao and Chai Shao's Jinhe Road belong to the Guannei Dao Military Region in the northwest; Li Yaoshi's Dingxiang Road and Li Shiji's Tongmo Road belong to the Hedong Provincial Military Region in the north; Heng'an Road of Wei Xiaojie and Changwu Road of Xue Wanshu belong to the Hebei Provincial Military Region in the northeast.

These six armies spanned the entire northern border of the Tang Dynasty and mobilized more than 100,000 troops, which was the largest military operation since the founding of the Tang Dynasty.

The generals who participated in the war were not only the most ideal lineup at that time, but also the ultimate combination that was difficult to match in other eras in Chinese history!!

The commander of the Five Paths Marching Army commanded more than 100,000 troops, all of whom were under the control of the Grand Governor Li Yaoshi.

Among the five marching commanders, Li Daozong, Chai Shao, and Li Shiji were all familiar with Pharmacist Li.

Nearly two years ago, Xue Wanshu recommended Xue Wanche to be under the command of Pharmacist Li, which is considered old, not to mention that this time, Xue Wanjun is Chai Shao's deputy general.

Interestingly, Li Daozong was the king of Rencheng County from Yipin, and his order was before the Duke of Guo; Chai Shao is Huo Guogong from Yipin; Li Shiji is Cao Guogong from Yipin; Xue Wanshu is the Liang Jungong of the second grade; Even Pharmacist Li's deputy general, Zhang Gongjin, is also the Dingyuan County Duke of Zheng Erpin.

At that time, the titles of each of them were higher than that of the Yongkang County Duke of Li Yaoshi.

As for Wei Xiaojie, there are few records of him in the history books.

It is only known that he was born in the Wei family of Xia County, and he is the descendant of the famous beautiful man Wei Jue in the Western Jin Dynasty.

Originally, Shi Sui was a general, and when the Tang army attacked Chang'an City, he fought and was defeated by the Tang army.

After returning to the Tang Dynasty, he went out with Li Shimin to fight Liu Wuzhou, and defeated Wei Chi Jingde in Meiliangchuan, which can be seen to be also a great general.

Youzhou, on the other hand, was originally the base of Luo Yi's forces, and went through two rebellions by Li Ying and Wang Junkuo.

His defender Xiaojie served as the governor of Youzhou, which was obviously trusted by Li Shimin.

Each of the six marches has a different mission.

Li Daozong's great fellow is the left wing, and his deputy will be Zhang Baoxiang.

The "Datong" here is not Datong in Shanxi, and the city of Datong at that time was located near the former banner of Urad at the southern end of the Wuliangsu Sea in present-day Inner Mongolia, where it was possible to contain reinforcements from the west, including Shabo Luoshe.

Chai Shao's Jinhe Road was the left army, and after he took Shengzhou, he crossed the Great River to the outside of the Tao, and advanced all the way north along the Jin River, which is the Dahei River in present-day Inner Mongolia, with the aim of threatening the rear of Dingxiangya from the west.

Pharmacist Li's Dingxiang Road is the Chinese army.

After taking Mayi, the Daizhou Road troops led by him were relocated to Dingxiang Road, which was about to cross Luliang Mountain and advance in front of Dingxiang Ya Tent from the south.

Li Shiji's road to the desert is the right army.

He first went out of Bingzhou to the north, and then crossed the Luliang Mountain to the west, with the aim of threatening the rear of the Xiangya tent from the east.

Heng'an Road on Wei Xiaojie is the right wing, and Heng'an is located in the north of Yunzhong, where it can deter reinforcements from the east of Jieli, including Tuli.

Xue Wanshu's Changwu Dao is the right flank, where he monitors movements in various parts of the east, which can cover the tribes that have surrendered to the Tang Dynasty earlier, and at the same time restrain other tribes from rushing to the aid of Jieli.

As Pharmacist Li deduced before, as soon as Li Daozong came out of Lingzhou, he encountered a sand bowl.

What a figure Li Daozong was, after repelling it, he advanced first to the north and then to the east along the great river.

Tuli learned that the Tang Dynasty was out of the army, and immediately attached the table, and soon Yu Shot also led the department to surrender.

Li Shimin was very emotional, and said: "The former emperor called himself a subordinate to the Turks for the sake of the people, and I am often sad. Today, I am only in the house, and I am ashamed of the snow. ”

There are also Dangxiang, Yao, Dongxie, Nanxie, and Keke...... Many distant tribes have sent envoys to pay tribute.

The costumes of the various tribes are very different, or the crown of bearskin, or the forehead of gold and silver, or the cloth of wool, or the vepi of the silk and wear...... And so on.

The Chinese book waiter Yan Shi Gu played: "In the past, when King Wu of Zhou was in the world, the world was peaceful, and the distant country returned the money, and the history of Zhou was written as the "Wang Hui Chapter".

Now that all countries are coming to the court, this generation's chapter service can be written. ”

So Li Shimin ordered the great painter Yan Liben to paint this scene into "Wang Hui Tu", which has been passed down to this day.

However, the affairs of the world cannot be perfect after all.

In the midst of many good news, it is inevitable that there will be shortcomings.

Du Ruhui has been working hard for more than ten years, eating and drinking, and his mental strength has long been overdrawn.

Now that the preliminary work of the Turks had come to an end, he was a little relieved, and then he fell ill immediately.

I had to resign from all my positions and recuperate at home.

There is a leap month after December in the third year of Zhenguan.

According to the modern calendar, it is impossible to have a "leap December", but the early Tang calendar is different from the modern one.

In any case, this is the coldest time of the year.

Two months ago, Pharmacist Li took Mayi, and the troops he led were changed from Daizhou Road to Dingxiang Road, but he did not immediately advance to Dingxiang with his division.

Because in the past ten years, Ma Yi has changed hands several times between the Tang Dynasty and the Turks.

Once he left with his army, it was likely that the area would be invaded by the Turks, which would put him in a situation where he would be exposed to the enemy.

Before advancing north, Pharmacist Li had to stabilize the situation in Mayi.

Between Mayi and Daizhou is the upper reaches of the Sanggan River, from which the forces of various tribes are stationed on both sides of the river.

After Li Shimin issued an edict to march against the Turks with a six-way march, Li Yaoshi immediately ordered as the chief administrator to order Li Shiji to lead the army from Bingzhou to the north to the middle reaches of the Sanggan River to control the situation in this area.

He also ordered Wei Xiaojie to lead the army from Youzhou to the lower reaches of the Sanggan River to control the situation in that area.

Then Pharmacist Li led the army to leave Mayi, and there were no longer worries.

At that time, the Shabo Luoshe in the west had been repelled by Li Daozong, the Yu Sheshe in the south had been subjugated to the Tang Dynasty, and the Tuli in the east and many subordinate tribes had also been annexed.

Now Chai Shao is threatening Jieli's right rear from the west, and Li Shiji is about to threaten his left rear from the east.

Directly ahead of Jieli, Pharmacist Li was preparing to advance from south to north.

Jieli's intelligence doesn't stop there.

After the upper, middle, and lower reaches of the Sanggan River were all controlled by the Tang army, he could not know the exact movements of the other party.

However, Jieli was very familiar with this area, and although Li Yaoshi had crossed the Sanggan River and taken Mayi, if he tried to go north and threaten Dingxiang, he must first cross the Luliang Mountain.

After that, there are three natural hazards, from south to north in order for Shanyangling, Zihe, and Evil Yangling.

These three places are in today's Inner Mongolia and Lingle County, of which the Purple River is the Ulan Mulun River, also known as the Hunhe River.
