The Han's military deployment in Guanzhong was based on Wei Yan's 35,000 soldiers stationed at Qishan and Jiang Wei's 15,000 soldiers and horses garrisoned at Wuzhangyuan. They built a defense line in the narrowest places in the north and south of the Guanzhong Plain by watching each other.
The rest include more than 4,000 people from Wang Ping's department garrisoning in Qixian County to curb the possibility of Wei troops entering Longdong from the Jingshui River Valley; more than 10,000 people from Wu Bandu are stationed in Chencang City, overseeing the rear farming affairs; Zhao Guang's department and the Xiliang Cavalry garrison On the east bank of the Lishui River Valley in Yong County, he was responsible for daily vigilance and assistance in supporting various ministries in the war.
As the Wei army saw, the Han army had approximately more than 70,000 troops, and they were widely dispersed.
Once the Wei army is determined to break the cauldron and gather all its troops to march to Chencang, it will inevitably make it impossible for the Han army to regroup and fall into fighting independently, and then the Wei army will defeat them one by one with their superior strength.
In fact, all the generals and generals of the Wei army had long understood this obvious flaw.
There were also many generals who used this advice to advise Emperor Cao Rui and Sima Yi to seize the opportunity.
However, similar advice was previously rejected by Sima Yi on the grounds that he should not act rashly.
It's not that he is fearful or has selfish motives.
On the contrary, at that time, even Emperor Cao Rui had the same view as him - looking at Ni Shu's plans and deployments over the past ten years, you will find that in such obvious flaws, murderous intent often lurks!
Yes, they all felt that the flaw was exposed deliberately by Ni Shu, and his original intention was to induce the Wei army to initiate a decisive battle.
But as time went by, the number of soldiers from various tribes mobilized against Shu to attack Wu and their demonstrated combat power made both Cao Rui and Sima Yi slowly overturn this view.
Maybe Ni Shu didn't do it on purpose?
This kind of troop deployment that seems to be comprehensive, but actually loses the mobility of mutual rescue, is it a last resort due to insufficient troop strength?
With this kind of thinking in mind, Sima Yi, who mixed selfishness into his decision-making, quickly annihilated all doubts and made one hundred thousand cavalry drive to the Lianshui Valley at lightning speed.
At the beginning, the Han army was indeed caught off guard.
After all, no one expected that the Wei army, which had been retreating and defending passively, would be so decisive this time.
It also made Sima Yi's tactic of taking advantage of the enemy successful.
Some of the Han army's farmland in Qianweizhihui, Yong County, fell into the hands of the Wei army because they did not have time to seize it and were reluctant to burn it.
This also greatly boosted the morale of various departments in the Wei army.
Just like a person trapped in a quagmire who inadvertently grabs a vine and becomes radiant with endless hope of survival, they, who have experienced too many defeats, also see the dawn of victory when their tactics are successful.
Moreover, the progress of the war situation has begun to move towards the expectations before the war.
Due to the mobile strength of the Han army, Zhao Guangbu and the Xiliang cavalry could only cover the retreat of the Tuntian Lishu to the Yangcheng area in a hurry, and had no time to use the superiority of the cavalry to disrupt the Wei army's advance.
In Chencang City, the Wu Ban tribe closed the city gate tightly and planned to defend it to death.
Jiang Wei's tribe in Wuzhangyuan was sent to the plains, but the number of soldiers who appeared on the south side of the Weishui River Valley was only about seven or eight thousand, not all at the same time.
If nothing else, he probably had to leave some soldiers behind to work on the autumn harvest in the plains.
Only the Wei Yan tribe in Qishan was different.
He only left a few thousand soldiers to guard the camp, while the remaining 30,000 soldiers all came out and slowly headed towards the Lianshui River Valley.
He actually planned to fight alone in the wild with three times as many enemies!
Yes, just fight it alone.
Because after Sima Yi arrived in the Lishui River Valley, he did not immediately cross the river to besiege Chencang. Instead, he first separated the tiger and leopard cavalry to go north to Linyang City to prevent the Han cavalry from returning south to support Wei Yan's tribe; how to isolate Jiang Wei's tribe and Wu Ban
Sima Yi was also fully prepared for the troops coming to help.
He knew that Jiang Wei's troops on the south bank of the Wei River were too small. The Wei army only needed to detach a few hundred soldiers to stand guard along the river day and night, so that they would not dare to cross into the northern plains and be trapped in a tight siege. He also expected that if Jiang Wei wanted to fight, he would definitely
He chose to join forces with the Wu Ban tribe first, and then look for opportunities to come from the Lianshui Valley to support the Wei Yan tribe.
Marching like this takes a lot of time.
With the Wei army's 100,000 infantry cavalry on the side, would Wu Ban's troops dare to make Chencang City's defense weak and march out in full force?
Therefore, Sima Yi felt that Wu Ban and Jiang Wei were not in danger.
He had plenty of time and confidence to defeat Wei Yan's tribe first despite their frequent intrusions!
Coincidentally, the generals and generals of the Wei army were equally confident.
In the situation that Sima Yi had expected before sending troops, and after the Wei army realized the tactics of dividing Shu and attacking Shu, they were all looking forward to the moment when they could avenge their previous humiliation.
As for the only variable, for example, whether Zhuge Liang and Zheng Pu, the prime ministers who rebelled against Shu in the East Three Counties, can rush to Guanzhong in time to rescue...
They feel there is nothing to worry about.
Wang Chang, the general who conquered the south in the Zhushui River Valley in Xi County, was attacking Zheng Pu's camp in the Shu River;
Even if their strong men broke their arms and abandoned the three counties in the east, they still needed to get rid of the pursuit of Jingzhou soldiers and horses, walk through the Baoxie Valley or take the Chencang Road to enter Guanzhong.
Counting the time, by the time they entered Guanzhong, it was already too late to rescue Wei Yan's tribe.
In other words, all the generals in the Wei army felt that since Wei Yan dared to go out to fight alone, he would have to pay the price for his arrogance!
Pay an unbearable price for Ni Shu!
But what they didn't know was that Sima Yi was not so optimistic about the war situation.
First, it is due to the caution of being a governor.
On the other hand, it was unusual for Wei Yan's troops to come out so quickly and fight alone, which made him feel a little uneasy.
Obviously Wei Yan's troops can wait for more than ten days until Zhao Guang's troops and the Xiliang cavalry have settled the people in the field and can coordinate the battle before they come out.
No matter what happens, you can wait until the Wei army besieges Chencang City before coming out to rescue them!
Why so impatiently?
Could it be that he was so arrogant that he could defeat three times the Wei army with Luoyang Central Army as the main force with only more than 30,000 soldiers?
Sima Yi couldn't figure it out.
I don't think Wei Yan is a reckless general who can only show off his courage.
There must be something fishy about this!
He had a vague idea in his heart.
However, after he carefully considered all his deployments, the distribution of troops against Shu, and the situation between ourselves and the enemy several times, he could not find any omissions.
Of course, no matter whether the omissions were found or not, he would not change his intention to personally lead the troops to meet Wei Yan's tribe.
There is no turning back when you draw a bow.
They all came with desperate determination, how could there be any reason to avoid fighting!
In Xicheng of Dongsan County, when the Prime Minister heard that the Wei army in Guanzhong finally sent troops for a decisive battle, he immediately held up his palms and laughed, "It's all good!"
Immediately, he turned his head to look in the direction of Shu and murmured in a low voice.
"God is not kind to me. I will return to Shu again in this life..."
