After learning that Zhang Fei was going to lead an army of fifty thousand in the Northern Expedition, the first thing Sima Yi did was to increase the number of scouts sent to the surrounding area.
Although Sima Yi has been an official since then, he has never truly commanded soldiers to fight alone.
But Sima Yi is a person who is good at learning.
What's even more valuable is that Sima Yi was Cao Cao's close adviser for a long time.
During that period, even though Cao Cao never specifically taught Sima Yi anything, Sima Yi, who was good at learning, still learned many valuable military tactics from Cao Cao.
Perhaps before, Sima Yi's strategy and strategy was only in the realm of theory.
However, during the three years of garrisoning in Wancheng, Sima Yi had the opportunity to practice his strategy through his interactions with Li Yan.
Sima Yi cannot be called a famous general who is a genius, but what he is best at is using the existence of enemies to make progress step by step.
Sima Yi suddenly increased the number of scouts sent out, in order to find out as much as possible the next movements of the Han army.
Sima Yi, a thoughtful man, understood a truth.
What the enemy wants you to see may not be the truth.
And if you want to truly find out the truth, or get yourself closer to the truth, the existence of scouts is very important.
After waves of scouts were sent out and returned, Sima Yi quickly learned the following news:
"Report: Zhang Fei has arrived in Xinye!"
"Report: There has been some unusual movement among the Han troops stationed in Xinye!"
Not long after learning the above two pieces of news, Sima Yi received another piece of news that disturbed the soldiers and people of Wancheng.
"Zhang Bao leads an army of three thousand and is marching quickly towards Jiyang!"
After hearing the news, Sima Yi narrowed his eyes.
He did not listen to the advice of his subordinates and immediately sent reinforcements to Jiyang.
The reason why his subordinates were so anxious was that the ministers in Wancheng agreed that Zhang Fei would wait until the 50,000 Han troops were assembled before leading the northern expedition.
Even Sima Yi thought so at first.
Therefore, he only sent scouts to further explore the movements of the Han army in the past few days, but did not send reinforcements to Jiyang in time.
But Zhang Fei's movements were faster than Sima Yi and the Wancheng generals expected.
Three days ago, they had just received the news that Zhang Fei was going to lead an army of 50,000 in the Northern Expedition.
But just three days later, the vanguard of the Han army appeared outside Jiyang City.
Zhang Fei's unexpected move caught Sima Yi and the Wancheng generals off guard.
But Sima Yi was not as panicked as his subordinates.
Although he had not sent reinforcements to Jiyang in time before, because Jiyang was the main route for the Han army to advance north, Sima Yi had spared no effort in repairing Jiyang's city defenses in the past three years.
Moreover, what Jiyang is currently facing is that reinforcements cannot arrive in time, but this does not mean that there is not a certain number of soldiers in Jiyang City.
Even if Zhang Fei brings all the 20,000 Han troops in Xinye City, Jiyang City will still have no problem holding on for a while.
Now, compared to Ji Yang's safety issues, Sima Yi was more concerned about Zhang Fei's intention of using troops in this way.
He publicly released the news first, making himself think that he would wait until the 50,000 Han troops were assembled before going out for the expedition.
Under such circumstances, he led his army to attack Jiyang with lightning speed, hoping to catch himself off guard.
On the surface, Zhang Fei's purpose is to capture Jiyang so as to completely open the passage to the north.
This purpose, judging from the information collected so far, seems to be very clear.
The current generals in Wancheng all think so.
But Sima Yi, who was always cautious, felt that things would not be that simple.
Sima Yi seemed to feel that there was a layer of fog lingering in his heart, making him always feel uneasy.
But now he couldn't get through the fog.
While Sima Yi was thinking hard, the subordinates on the side urged him more and more urgently.
"General, you can't throw Ji Yang away!"
This reminder from his subordinates woke up Sima Yi.
Yes, no matter what Zhang Fei's true purpose is, Ji Yang is an existence that cannot be given up.
Once Jiyang is captured by the Han army, the southern part of Wancheng will be undefendable.
After realizing this, Sima Yi quickly began to mobilize his troops.
He looked at the general who reminded him - Niu Jin.
"Immediately lead five thousand troops and set off for Jiyang. When you arrive, if the bandit army has already begun to siege the city, there is no need for you to rush into the city.
We can gather as far north and south of Jiyang City, and your generals can gather there."
After hearing Sima Yi's general order, Niu Jin immediately took the order in a deep voice and left.
Watching Niu Jin leave, Sima Yi said to the remaining generals:
"Everyone, you can go back and pack your bags. In a few days, I will lead the rear army to Jiyang."
Sima Yi's general order puzzled the generals, but they did not openly disobey Sima Yi's general order. After saluting, they left the hall one after another.
Sima Yi could naturally see the confusion on the generals' faces.
Sima Yi also knew why the generals were puzzled.
As the saying goes, saving a city is like putting out a fire, and Jiyang City is an important city. When the Han army is approaching the city, under normal circumstances Sima Yi should send out all the troops to support it.
But Sima Yi initially sent out only 5,000 sergeants.
Five thousand sergeants sounds like a lot, but facing 20,000 Han troops, self-protection is risky, let alone cooperating with the garrison inside and outside the city to defeat the Han troops.
And if Sima Yi reported the purpose of not rescuing Jiyang, there was no need for him to let Niu Jin lead 5,000 soldiers to Jiyang, and there was no need to say that he would personally lead the army to Jiyang next.
Sima Yi's arrangement sounds very contradictory, which is why the Wancheng generals are puzzled.
Save or not, it’s better to be happy!
What the generals didn't know was that the reason why Sima Yi made such an arrangement was that he suspected that the Han army wanted to encircle the area for reinforcements.
The tactic of encircling a point to mobilize reinforcements was used by Guan Yu during the Battle of Xiangfan.
It can be said that everyone knows how miserable the Wei army ended up in the field battle with the Han army under this tactic.
Although it is difficult for the Han army to gather a luxurious lineup of Guan Yu, Zhang Fei, and Ma Chao with tens of thousands of enemies at the moment, even if Zhang Fei is the only one in the Han army, the field combat capability of the Han army cannot be underestimated.
This chapter is not over yet, please click on the next page to continue reading! "When riding a chariot, both men and horses are torn apart." This sentence is a true portrayal of Zhang Fei's bravery during the Battle of Xiangfan.
Under this true portrayal, Sima Yi couldn't help but feel jealous.
The reason why he asked Niu Jin to lead 5,000 Wei troops first was to inform the defenders in Jiyang City that reinforcements had arrived so that they could continue to hold on.
On the other hand, Niu Jinnai is a rare warrior in Wancheng.
In addition, the terrain of Nanjiuju is steep, easy to defend and difficult to attack, so that the real purpose of the Han army can be further explored while ensuring the safety of the army.
From the perspective of preventing being surrounded and calling for reinforcements, Sima Yi's arrangement was very appropriate.
But Sima Yi always had a bad feeling in his heart, as if he had overlooked something crucial.
what is it?
...
Niu Jin led five thousand Wei troops and soon arrived at Nanjuju, not far from Jiyang City.
Niu Jin was a general under Cao Ren at first, but after Cao Ren died in battle, Niu Jin stayed in Wancheng.
Later, after Sima Yi took control of Wancheng, Niu Jin took advantage of the situation and became Sima Yi's general.
As early as when he was under Cao Ren, Niu Jin was often entrusted with the task of attacking fortresses by Cao Ren because of his bravery.
After joining Sima Yi, Niu Jin's bravery was further appreciated by Sima Yi.
Although Niu Jin fought bravely, he was not a reckless person.
Just after he led his troops to Nanjiu Ju, he heard a report from the scouts, saying that the Han army had already set up camp outside Jiyang City.
And judging from the behavior of the Han army, they seemed to be surrounding Jiyang.
After hearing this military information, the deputy general asked Niu Jin if he wanted to lead his troops into the city to join the defenders before the Han army's encirclement situation was formed.
Without Sima Yi's advice, Niu Jin would probably have adopted the lieutenant's suggestion.
However, in order not to disobey Sima Yi's orders, Niu Jin finally chose to set up camp in Nanjiuju, forming a rivalry with Jiyang City.
After making arrangements for the camp, Niu Jin personally wrote a military report and sent it back to Wancheng.
In the military report, Niu Jin reported to Sima Yi all the military information he had discovered.
In Niu Jin's report on the military situation, he mentioned two very important points.
The first point is that there are indeed a large number of Han troops gathered outside Jiyang City.
The second point is that the leader of the attack on Jiyang City was undoubtedly Zhang Fei from the general's flag.
This military report only lasted two days before it was quickly sent back to Sima Yi in Wancheng.
Sima Yi looked at the military report sent back by Niu Jin. After thinking for a long time, he finally made a decision.
On the second day, Sima Yi led 10,000 troops south to rescue Ji Yang.
As a strategic location to defend Luoyang, Wancheng has always been heavily stationed.
If Zhang He's 10,000 sergeants are added before, there will be 30,000 Wei troops in and around Wancheng alone.
However, as Zhang He led the army to leave, Niu Jin took another 5,000 soldiers southward. Currently, there are only 15,000 Wei troops inside and outside Wancheng.
It was impossible for Sima Yi to lead all the 15,000 Wei troops out of Wancheng, leaving Wancheng in an extremely empty state.
When Sima Yi led his army to leave Wancheng, he specifically said to the remaining Wancheng garrison:
"After I lead my army to leave, you must send scouts to patrol the surrounding area day and night, and do not let your guard down.
I will lead the troops south to gather together. If there is any emergency military situation, you should report it to me in time."
The one left by Sima Yi to defend the city was Dai Ling, a veteran of Cao Wei.
Although Dai Ling is not a well-known general, he has been in the army for many years and has always been loved by all the previous commanders for his calm military style.
It was precisely because of Dai Ling's characteristics that Sima Yi left him to garrison Wancheng.
But despite this, Sima Yi still gave Dai Ling several instructions in succession.
Faced with Sima Yi's repeated instructions, Dai Ling did not dare to neglect. He repeatedly promised Sima Yi that he would not take it lightly.
After receiving repeated assurances from Dai Ling, Sima Yi finally led his troops away with confidence.
But what Sima Yi didn't know was that on the day he led his army to leave Wancheng, a Han army scout hidden outside Wancheng noticed the movement of his army leaving and immediately returned to the south. Like Mi Han
