In the 21st century, Zhangbei County is north of Yinshan and Zhangjiakou is south of Yinshan. The distance between the two places is 90 miles in a straight line, and the length of the road is about 100 miles. On the road between these two places, you will have to go through the Wild Fox Ridge.

The Battle of Yehuling was a decisive battle that took place in August 1211 (the third year of Jin Da'an and the sixth year of Genghis Khan of Mongolia) and decided the fate of both the Mongol and Jin dynasties. In this battle, Genghis Khan commanded 100,000 troops to concentrate on attacking the 100,000 troops in the middle of the 450,000 Jin army, and the Mongol army won a great victory, and the Jin State lost almost all its elites.

On June 24, 323 of the Great Song Dynasty, General Li Yun led four battalions of troops across the Yinshan Mountain Road and arrived at Yehuling. At this time, the Song army had already built three fortresses on the mountain road of 100 miles, and it was not as troublesome as imagined to travel through it. But when the troops were all in summer clothes, marching in the Yin Mountain, everyone felt a little cold. When he arrived at the foot of Yehu Ridge, the chief of staff sighed: "This place is called Yin Mountain, could it be because of the cold?" ”

Li Yun couldn't answer such a question. Chinese words like to be more festive, and such a 'yin' word gives people an unfriendly feeling. The poem that can make the soldiers feel high-spirited is probably only 'But make the dragon city fly, don't teach Huma to do Yin Mountain'.

"Be sure to bring more clothes next time." Li Yun expressed his opinion, and then looked up at the famous Wild Fox Ridge. As far as Li Yun has seen, except for the strong coolness of Yehuling in the middle of summer, there is nothing special about itself. It's not particularly suitable for ambushes, and it's not particularly suitable for launching a formation battle.

After watching it for a while, Li Yun asked the chief of staff, "If you were asked to fight here, how many troops would you invest?" ”

The chief of staff was also looking at the terrain, and after listening to the question, he replied: "If it were me, I would build a camp here." Two or three thousand people is the limit. I don't understand why Jin Guo put 100,000 troops here. ”

Li Yun sighed: "In the war history class, Jin Guo wants to play a hammer deal. I used to think that Jin Guo's idea was very nonsense, but now I understand their thoughts a little. Maintain an army of 100,000 here, and probably be eaten down first. If there were no steam wagons and ships to transport grain and grass, we would have stationed 40,000 soldiers and horses in Youzhou, and they would only have survived by relying on military camps. Not to mention mobilizing food from Youzhou to support Wucheng. ”

The chiefs of staff are very familiar with logistics, and logistics must be taken into account in any operational plan. This time, Wucheng, which was able to reach 400 miles away, relied on a large amount of grain in Youzhou City. Even so, this time the troops were only prepared to leave one division of troops in Wucheng. Even a division has had a lot of discussions, and it feels that the logistical burden is very heavy. This division itself has to bear part of the production.

So the chief of staff also sighed: "The chariots, the horses and the pedestrians, bows and arrows are at their waists." Ye Niang's wife went to see each other, and the dust did not see Xianyang Bridge. The clothes stopped crying, and the crying went straight to the sky. I used to think that guarding the border was very majestic, but now I know that what is written by the military vehicle shop is true. It's really sad to be ready to fight with Hulu at all times in such a place. ”

The Great Song army was a very normal army, and a normal army naturally had the reaction of normal people, and after seeing the difficult environment, they would question the defense of the border. After a terrible war, you will yearn for peace. Li Yun naturally would not accuse the chief of staff of disturbing the morale of the army, everyone is not a fool, and they will naturally have thoughts after seeing the situation in Yinshan. He smiled: "Then let's continue to go north and take a look north of Yinshan as soon as possible." ”

After resting for the night near Yehuling, the troops continued north the next day. After passing through the last few mountain passes, the scenery in front of me suddenly changed to a vast flat grassland north of the Yinshan Mountain Range. Walking through the mountains for a long time, the soldiers facing the grassland unconsciously smiled.

Li Yun couldn't help but smile, and the Arabian horse under his crotch couldn't help but gouge the ground with his front hooves, as if he wanted to run on the land. The chief of staff sighed, "No wonder! No wonder! No wonder our Han army will kill to the north of Yinshan as long as there is a chance. As long as you can, who would let go of such a place! ”

"Okay, let's go where we can!" Li Yun said loudly. He no longer wanted to maintain the demeanor of a commander at this time, he personally came here to see what the land that must be taken in the future was like, and how he could stand.

The troops then advanced, and Li Yun led the cavalry forward. After an hour, the sound of horses' hooves was no longer the sound of hooves colliding with the stone road, but the sound of stepping on thick earth. However, at this moment, I saw some riders in the distance, and they saw that their outfits were not Han at all.

Seeing the movement of thousands of cavalry, those riders watched from afar. As soon as Li Yun waved his hand, a group of cavalrymen using Type 22 rifles went in the direction of those riders, and some riders immediately urged their horses to leave. There are also a few people who are obviously bold, and they didn't leave after seeing Song Jun, but let Song Jun reach him about 100 meters.

The horsemen reined in their horses, took aim with their rifles, and a platoon of guns passed, and the riders were dismounted. The horses were frightened and ran away when they heard the gunshots, and the Great Song cavalry quickly brought back the few guys who had been put down. There were four of them, two of whom were killed, one seriously wounded and one lightly wounded.

Li Yun asked, "Can you understand Chinese?" ”

The lightly injured guy was muttering something, and Li Yun couldn't understand a word. In this case, Li Yun did not talk nonsense, and explained to his subordinates that he was "killed". Li Yun urged the horses to start galloping on the edge of the grassland.

As mentioned in history class, in the fourth year of Zhenguan, the area north of Yehuling was returned to the Tang Dynasty. About fifty years later, it fell into the hands of the Khitans, and it has been 600 years since then. For 600 years, the cavalry of the Han Chinese has once again galloped here.

The crisp sound of gunfire rang out, and it was supposed that his subordinates were executing the two aliens who didn't know what language they spoke. Li Yun continued to ride forward, and did not look back at all. The Arabian horse, which had not seen a plain for a long time, was finally able to run to its heart's content, and it was running on all fours like a pop in the grassland.

Half a month after Admiral Li Yun had run his horse on the edge of the grassland, Hao Ren Wanhu, who led his troops north, received the news that the Song army had arrived at the edge of the grassland.

Hao Ren Wanhu expected this, he knew that the Great Song Dynasty would never be satisfied with only recovering Hebei and Youzhou, and it was only a matter of time before he continued to go north. But when this day really came, Hao Ren Wanhu was still extremely sad in his heart. For hundreds of years, it was the northern forces that pressed over the Han forces in the south. After hundreds of years, this situation has finally been completely reversed.

At this time, Hao Ren Wanhu remembered a Xiongnu folk song thousands of years ago.

The loss of my Qilian Mountain will make my six animals restless.

I have lost my mountains, and my women have no color.

The loss of my mountain makes my women colorless.

The loss of my Qilian Mountain will make my six animals restless.

The death of my Qilian Mountain made my six animals restless.

The loss of my self and the mountains have made my wife colorless.
