Xi'an Prefecture, that is, the Haiyuan of later generations, is a rare treasure land on the border of Song and Xia. The water and grass are abundant, the grassland cultivated land is very much, although it is located on the west side of the Loess Plateau and the territory is hilly and undulating, the ravines are vertical and horizontal, the remaining veins of Liupan Mountain (Nanhua Mountain, Xihua Mountain, Moon Mountain, etc.) run through the north and south, but before being given the name Anxi Prefecture, Tiandu Mountain is really famous in the Song and Xia countries.

Anyone who knows anything about the situation in Song Xia will not be unfamiliar with it.

The two armies of the Song and Xia have been facing each other here for decades, and at the peak of the Song army, they set up more than 30 military walls and city walls there. And the party members also built palaces and cities there, not to be outdone.

During the reign of Shenzong, the Song army attacked the Western Xia several times, and finally broke the enemy in Tiandu Mountain, and many walled cities belonging to each other were captured. The Xixia Palace was also burned to the ground.

However, thirty years in the east of the river and thirty years in the west of the river. With the southward movement of the Jin soldiers, the western army was sent east again and again to reinforce, and the party took the opportunity to fall into the ground, Li Qianshun sent troops to break Xi'an Prefecture, and recaptured Tiandu Village, and made Xi'an Prefecture Anzhou.

Even if Zhao Gou expelled the Jin Yu, the prestige of the Song army was greatly enhanced, and Li Qianshun sent envoys to sue for peace several times. But the Xia army's garrison in Tiandu Mountain did not see them reduce a single soldier, let alone they obediently sent Tiandu Mountain and Xi'an Prefecture back to the hands of the Great Song Dynasty.

The first goal of the Song army in Weizhou was Tiandu Village in Tiandu Mountain, and then to recover Xi'an Prefecture. Then they will march north, kill the Xishou Baotai military division of the western thief, and after they succeed, they do not need to attack Lingxia to the east, nor do they need to attack the Hexi Corridor to the west, they only need to stand firmly on their roots and cut off the connection between the party members on the east and west sides.

On the whole, Western Xia is an irregularly rectangular country, but if you look closely, you can see that there are too many deserts and Gobi deserts in the territory of the Dangxiang people.

Their true essence is on both sides of the Yellow River east of Helan Mountain, that is, in the later N Xia, and then there is the narrow line along the Song-Xia border in the east, along the Hengshan Mountain, and the Hexi Corridor to the west.

This is a country with a "┻" shape.

The goal of the Song army in Weizhou was not to capture the stick, but to cut off the area east and west of the stick. As long as this can be done, after the Song army on the East Road seizes the Yinxia Prefectures and recovers the essence of Xingqing Mansion and other essential places, then Li Qianshun will still have to resist to the end, and he will not surrender to death, but he can only take the remnants of the party and throw himself straight to the desolate desert Gobi in the northwest, and cannot retreat into the Hexi Corridor along the west of the Yellow River.

Of course, if Li Qianshun was willing to throw away the remnants of the party and ride away like west, then the Song army in Weizhou would not be able to stop him.

But in this way, Li Qianshun is equivalent to throwing away his basic plate. The essence of the party is all in Helan Mountain, and the Hexi Corridor was taken from the Ganzhou Uighurs.

Li Yuanhao's generals once slaughtered their troops to Yumen Pass, but in the end they still did not take that step towards the Western Regions. After the soldiers arrived in Dunhuang, they died down. Because further on, there were not only the remnants of the Ganzhou Uighurs, but also the powerful Western Uighurs. The latter, also known as the Uighurs of Gaochang, occupied most of the Western Regions.

Then the remnants of the Ganzhou Uighurs completely withdrew from the Hexi Corridor and became the Yellow-headed Uighurs, which were distributed south of Dunhuang, east of Khotan, north of the Qaidam Basin, and west to the area of Jimo, Ruoqiang, and Lop Nur. It had close relations with the regimes of Gaochang, Khotan, and Tubo Dong Yu, and often maintained tributary relations with the Song and Liao dynasties in the name of "Shazhou Uighurs".

Yue Fei did not know if the imperial court had already made contact with the Huangtou Uighurs, but with the defeat of the Hehuang Qingtang regime, the Huangtou Uighurs had already offered their knees to the Zhao and Song dynasties. The fault was not that Tong Guan underestimated the enemy and forced Liu Fa to send troops, so that the Song army was defeated, and it was not possible to guarantee that the yellow-headed Uighurs had already planted the banner of the Great Song Dynasty.

Yue Fei felt that it was likely that the imperial court would beat the rabbits with grass this time and kill the yellow-headed Uighurs.

Anyway, the Western Uighurs have already decayed? His king, Bilge, did not even dare to provoke Yelu Dashi, which was only a mountain away from him, and sat back and watched Yelu Dashi entrench himself for five years in the Beiting (former Tang Beiting Metropolitan Protectorate) at the northern foot of Bogda Mountain (the eastern section of the Northern Tianshan Mountain).

In five years, Yelu Dashi has developed from the original 200 guards to the current gathering of seven prefectures, including Weiwu, Chongde, Huifan, Xin, Dalin, Zihe, and Camel, as well as the people of the eighteen kings of Dahuangmurowei, Dira, Wang Jira, Chachira, Yexi, Nose Gude, Nira, Dara, Damili, Mierji, Hezhu, Wuguli, Zhubu, Pusuwan, Tanggu, Kumusi, Xi, and the eighteen kings.

How could such a monarch support the yellow-headed Uighurs?

When the Song army destroyed the Uighurs, her sister Princess Gaochang and the leaders of the Great Empire surrendered to the Tang Dynasty, but they did not see the slightest movement of the Xizhou Uighurs.

Perhaps the future enemy of the Song army will not be the defeated Xizhou Uighurs, but the vigorous and upward Yelu Dashi.

Yue Fei was very familiar with this name.

Because he was less than twenty years old, he also served in the army to conquer Liao, and he was quite appreciated by Liu Tao for his true defense under Liu Tao. It's just that the timing was unfortunate, Yue Fei's father Yue He died of serious illness, and Yue Fei could only bid farewell to Liu Tao and return home to keep filial piety.

If this were not the case, he would not have appeared in Liu Rui's (Wang Boyan) army, I am afraid that he would have been promoted to a high position by Liu Tao, who has a good eye for talent.

And the battle of Xuanhe led by Tong Guan in the Liao Expedition really made a name for Yelu Dashi and Xiao Gan.

Obviously, they were all elite warriors deployed from the Western Army, but they were brutally defeated by Yelu Dashi and Xiao Gan with a group of remnants. It's really frustrating.

For Yue Fei, that was a great shame. The Liao people didn't see it, and the army was defeated in a daze.

And the names Yelu Dashi and Xiao Gan have also been firmly engraved in his heart since that time.

And to this day, Xiao Gan, the king of Xi who established himself as the king after the fall of the Liao State, has rotten bones, but Yelu Dashi, who killed Xiao Yixue and Po Likuo at the beginning, and led two hundred iron horsemen to escape by night, has made a lot of momentum in this Western Regions.

Thinking that it would be possible to encounter the thief Yelu Dashi again in the future, Yue Fei felt a fierce fire in his heart.

……

Late at night, the lights in Tongyuan Village were bright.

Yue Fei, who led 2,000 cavalry to this village three days ago, had washed away the fatigue of running around for days, and was in good spirits at the moment, and his fine armor exuded a dark luster against the background of the torches. He rode his horse slowly in front of the two thousand iron horsemen, and his loud voice broke the peace of the military village: "Sons and daughters are listening to me, there is a way to raise soldiers for a thousand days and use soldiers for a while, we are full of the favor of the court, everyone does not worry about eating and drinking, and every family has food and clothing, which is Your Majesty's grace." Now that the Holy Son of Heaven wants to settle the grudge with the Western Thief for many years, how dare my martial artist not follow the power of dogs and horses? ”

"Not to mention that the enemy is weak and I am strong, and the heavenly soldiers have the help of earth-shaking thunder, can the western thieves stop my soldiers? This is the time for her husband to make a difference. ”

"Sons and daughters will fight hard with me, and they will win a wife and son with a shot and a knife on this battlefield, and they will glorify their ancestors."
