"You guys are so cold that your teeth can't be closed, let's go back to the city first!" Lin Yuan saw that Huang Xu and the soldiers were shivering from the cold, and he didn't care about saying more, so he welcomed the soldiers and horses into the city first.

Although the soldiers of the Han army had cotton clothes, they could not completely defend themselves against the cold, and they walked along the Yellow River for 100 miles, and they were almost frozen by the river wind.

When the soldiers and horses entered the city, Lin Yuan ordered his subordinates to take the soldiers to rest, and then led Huang Xu to the palace.

On the way, Lin Yuan said to Huang Xu: "Your Majesty expects that Cao Zhen will retire soon, so he has made a plan to deal with him at Tongguan Road, so he sent Da Sima to lead 40,000 troops here, and find a place to camp and intercept him through Huayin."

Let Cao Zhen go out first, and then His Majesty will pursue from the rear, and attack Cao Zhen back and forth, my army has just arrived today, and Da Sima is preparing to send someone to tell you tomorrow, I don't want you to come by yourself. ”

While the two were talking, they had already arrived at the palace.

Zhuge Liang is discussing with the generals in the palace.

In the main hall, in addition to Zhuge Liang, there are also Wei Yan, Lin Xiao and other generals.

Zhuge Liang said to the generals: "Tomorrow, you will follow me to the Tongguan Road, and I will find a place to arrange soldiers and horses......"

Lin Yuan walked into the main hall with Huang Xu: "Da Sima, who do you think I brought here?" ”

Seeing Huang Xu, Zhuge Liang frowned: "Zhengyang, why are you here?" ”

"Sin General Huang Xu has seen Da Sima!" Huang Xu fell to his knees with a thud.

"Defeated? Defeated at the hands of Sima Yi? Seeing Huang Xu claiming to be a criminal general, Zhuge Liang's face sank.

"The last general is incompetent!"

Zhuge Liang asked, "How many soldiers and horses have been folded?" ”

"Nearly a thousand!"

Zhuge Liang breathed a sigh of relief, and immediately asked: "If you fold nearly a thousand people, you won't lose the camp, and you can tell me in detail." ”

Huang Xu replied: "That Sima Yi is very treacherous, every night in Tongguan let the soldiers shout, if I go out of the camp to defend, the soldiers will be cold and sick, if I do not go out of the camp, I am afraid of the Wei army raid." In the past four or five days, many soldiers have fallen ill because of this, and I have no choice but to retreat.

Sima Yi sent Cao Zhang......"

"It's dangerous, it's dangerous!" Zhuge Liang listened, and said with a happy face: "It's also thanks to the fact that the Tongguan defenders are from Hebei in the Central Plains, and they are negligent in the battle formation, otherwise you will only lose a thousand people."

It's hard to deal with, but you can divide your troops into groups and take turns guarding them. However, if the cold ground is frozen today, Tongguan is the most violent place of the river wind, dripping into ice, even if the officers and soldiers of our army have cotton clothes, it is difficult to resist the severe cold, and the soldiers will be sick after a long time, and this method can only last a few more days.

It is not easy for you to keep the soldiers and horses, but if you lose the weight of grain and grass, you must also be punished, first remember fifty military sticks! ”

"Thank you, Da Sima!"

Zhuge Liang waved his hand and said, "You have been hungry for a day and a night, go down to eat something first and rest well." ”

"The last will retire!"

After Huang Xu left, Wei Yan groaned: "Now that the camp under Tongguan is lost, if Cao Zhen withdraws his troops, Sima Yi can send troops to support." ”

The Han army camp was built under Tongguan, if Sima Yi led troops to support Cao Zhen, then Tongguan would be threatened, if the overall situation was the priority, Sima Yi would not dare to go out to support Cao Zhen.

But now that the camp is lost, Sima Yi has no such concerns, if Cao Zhen withdraws, Sima Yi can lead the army to support Cao Zhen.

Lin Xiao groaned: "I can only build two camps in Tongguan Road, one to block Cao Zhen, and the other to block Sima Yi." However, this is a bit risky, Cao Zhen has 90,000 soldiers and horses, and he is flanked by our army and His Majesty's troops before and after, there is no way to retreat, and he will definitely fight to the death.

Cao Zhen came from Chang'an, Sima Yi came out of Tongguan, and our soldiers and horses were caught in the middle, and it was easy to make mistakes. ”

Zhuge Liang sighed and said, "If you lose the camp, you can only do this!" Tomorrow I'll go with me to inspect the terrain! As long as the camp is well established, the Wei army will not be able to break through. ”

"No!"

On the second day, Zhuge Liang led his generals to the east to inspect the terrain.

At that time, Cao Zhen led the Chang'an soldiers and horses to retreat, and he must flee to Tongguan through Huayin, which is a narrow road more than 100 miles long, Zhuge Liang needs to build two camps on this 100-mile long road, a camp, to block Cao Zhen's retreat to Tongguan.

The other camp blocked Sima Yi from leading the troops and horses of Tongguan to help. If only one camp is built, it will be attacked by the enemy, and it will be more difficult to command and dispatch, and it will be easy to be breached.

Zhuge Liang and the generals inspected for a day, and finally selected two places with narrow roads and steep mountains as places to arrange their positions.

However, Zhuge Liang did not immediately set up camp, but returned to the camp to prepare materials.

This time the battle was a general battle of 200,000 people, and these two camps were crucial to this battle, if one was breached, the Han army would end in defeat, so it needed to be carefully prepared.

For example, a few days ago, Cao Zhang led his troops to intercept Huang Xu, due to lack of time, Cao Zhang only hastily arranged the formation, let a thousand archers shoot in the mountains, and did not build fortifications as auxiliaries, which caused the Han army to easily climb the mountains, occupy a high place to counterattack, and escape from the encirclement.

If Cao Zhang had enough time, he could dig a ditch on the mountain ridge and dig the slope of the mountain wall a little steeper, so that it would be impossible to climb, so that the Han army could not go up the mountain, and Huang Xu's 20,000 soldiers and horses were stuck in the middle, and they were attacked by the enemy in front and behind, and they could not escape at all.

Tongguan.

The first general reported to Sima Yiyu: "Governor Qiyu, Huang Xu has led his troops to be stationed in Huayin, but our army scouts found that Huayin's soldiers and horses are far more than 20,000, and the banners of Zhuge Liang, Lin, and Wei have been erected on the head of the city.

Moreover, Tongguan Road has always been infested by the Shu army, and the Shu army has also cut down trees on a large scale, and I don't know what they are doing. ”

Sima Yi said in a deep voice: "It seems that Liu Chan Zhuge Liang has guessed that the defenders of Chang'an will retreat, so the Shu army wants to arrange an ambush on Tongguan Road, and when the general's soldiers and horses pass through Tongguan Road, they will attack back and forth." ”

Cao Zhang heard the words and said, "I'm afraid they won't make it? Now that the cavalry of the Shu army has been transferred to the north to deal with Budugen, and Zidan still has 5,000 tigers and leopards in his hands, with the power of the tigers and leopards, can't he break through the interception of the Shu army? ”

Sima Yi shook his head and said: "If the Shu army arranges a camp in Tongguan Road, although the tiger and leopard riding is powerful, it is not so easy to break through the Shu army's camp.

And this time, if you intercept Huang Xu, the Shu army will definitely dig ditches and cut steep mountain walls in the mountains on the south side. When the time comes, the mountains will not go up, and the archers of the Shu army can attack our army unscrupulously. ”

Cao Zhang groaned: "Since the Shu army's defense line is difficult to be sudden, then don't give the Shu army a chance to arrange the defense line." Now the Shu army has not set up camps and fortifications in Tongguan Road. We should immediately inform the General and let him retreat with his troops. ”

Hao Zhao groaned: "Under the city of Chang'an, there are tens of thousands of people under Liu Chan's personal command, and he sent someone to inform the general that the defense line of the Shu army has not been established, and Liu Chan will not easily enlarge the general out of the city." ”

Sima Yi sat in his position without saying a word, and said after a long time: "Until now, there is only a battle against the water, if it continues to delay, Ma Chao will lead the cavalry back, and it will be even more difficult to retreat." In the spring, the Shu army continued to build the city, and the general's 90,000 soldiers and horses had no hope of returning.

The general had 90,000 horses, and if he was blocked, he would definitely fight to the death. Marquis Yanling, you take a team of cavalry, rush to Chang'an from the path, and inform the general to prepare to withdraw the army, the sooner the better. However, he must be cautious and cautious when telling the general to bring enough shields and other defensive equipment. ”
