On October 15, Sima Wang's vanguard encountered the Shu Han cavalry led by Zhang Zun about thirty miles from Yixian. After brief contact, both sides retreated. Then, the managers of both sides received the message.

"This Sima Wang is also coming quickly."

"Yes, brother, this old thief came too fast! Our new city in Weinan is not yet completely finished. ”

"Well, we didn't expect to arrive in Yixian so soon. Speaking of which, we also earned it. It's just that if our army does not have a strong fortress in Weinan, this grain route will never be safe. Therefore, this Weinan New City must be built. I can't say it, I can only fight with Sima Wang's main force first. ”

"Huh? All right! Brother, let's fight this old thief first, if we can kill this old thief, we can go directly to Chang'an! ”

"Hey, it's not that easy. Well, the order will go down, and the armies will gather and prepare for battle. Ordered Zhong Quan (Jiang Bin) to lead 5,000 Mandarin Duck Array soldiers and 3,000 crossbowmen to defend Yicheng. Fang Bo organized the people to step up the construction of the Weinan New Town, and if necessary, he could distribute money and food to the local people, so that they could help us build the city. We will take the remaining 32,000 people out of the east for ten miles to line up, and go to meet Sima Wang's house for a while! ”

"Oh, little brother, let's go down and give orders!"

……

On the 16th, Guan Yi led 32,000 Han troops to run into the 40,000 Jin troops led by Sima Wang, who had arrived in a hurry, fifteen miles east of Yixian.

Cao Wei didn't attach much importance to the defense of Yixian County back then, and even the Jin Kingdom with the newborn Jin didn't pay much attention to it. The reason for this is because the city outline of Yixian County is built on the north bank of Weishui. On the one hand, the Shu Han, which is small and weak, has difficulties in grain transshipment, and on the other hand, it cannot afford to raise too many cavalry. Therefore, the army of the Shu Han side did not dare to easily cross the north bank of Weishui until it completely defeated Cao Wei's Guanzhong army.

But now Guan Yi actually took Yixian on the north bank of Weishui. Although for the time being, I still can't understand why Guan Yi is so bold. But after all, Guan Da Sima has the super victory of the siege of Yang'an Guan at the bottom. Therefore, Sima Wang would not think that this was a fatal strategic mistake made by Guan Yi at all. He instinctively thought that Guan Yi must have relied on something to rely on to cross the Weishui so fearlessly-that's right! When Wei Boyu came back, he mentioned that Guan Zifeng seemed to have a magical thing in his hand, which could quickly build a large number of hard stone walls. If he builds another city on the south bank of Yixian......

Therefore, Sima Wang completely abandoned the so-called celebrity demeanor at this time, and when he received a message from his own scouts that he had discovered a large army of the enemy, and the distance was only five miles. He was not interested in slapping his horse to greet Guan Yi at all. Immediately ordered the whole army to begin to put on armor and set up formations.

"What time is it?"

"Back to the general, it's about three o'clock now."

"Well, herald! Li Fu led 10,000 infantry in front of the formation. Xun Kai led 3,000 archers forward, first shooting at the position, and then retreating behind the infantry formation. Zhan Qinggang (I will write about Zhanqing in the future), Ju An led 10,000 cavalry to the right side of our army three miles away. Wu Chao and Guan Ding led 10,000 infantry to line up behind Li Fu's formation. This general will lead 7,000 soldiers for his own formation! ”

"Whoa!"

With Sima Wang's order, the entire Jin army began to act quickly. After staying for half an hour, when Guan Yijun walked into Sima Wangjun's line of sight. The entire Jin army has been arrayed.

"Hehe, this Sima Wang, his soldiers are still very good, how did they finish the formation so quickly? Well, Amu, what else is there outside the other party's main formation? ”

"Da Sima, three miles to the north, there are about 10,000 or so enemies."

"Hahaha, it's dusty, I see it all. Anything else? ”

"There are no other discoveries yet."

"Good, let's get started! It's rare that the people of the Sima family don't learn their ancestors to play turtle warfare, how can they not fight a good battle? Heralds! ”

"I'll wait for Da Sima's orders!"

"Order Zizhao (Wang Mai) and Zichun (Jiang Su) to lead two thousand crossbowmen forward and shoot at the position. Then Ling Xing and Zicheng (Luo Xi) led 10,000 spearmen to go out and engage the enemy! ”

"Order Guowei and Zhongyuan to lead 10,000 cavalry north to line up. Respond to the opponent's cavalry raid at any time! ”

"This general will personally lead 10,000 tiger infantry troops as the follow-up! That's it, go for it. ”

"Whoa!"

With Guan Yi's order, the Han army began to change formations rapidly, and then began to advance towards the Jin army's military formation!

The archers and crossbowmen on both sides begin to retreat after completing their fire. Then, the first array of soldiers on both sides collided fiercely!

"Drop!" Dozens of brass whistles sounded almost simultaneously, and then the officers of the gun formation spoke at the same time: "Stab to the right!" Countless spear heads were stabbed out in unison, and the soldiers on the front line of the Jin army suddenly burst into screams.

Sima Wang knew that Guan Yi was very powerful, but he didn't have a specific understanding of what kind of powerful method it was.

In the battle of Xindu, no one in the entire Deng Ai army ran back to Yongliang. So how Deng Aijun was defeated, no one in the Jin Kingdom knew it. In their calculations, the general conclusion is that Deng Ai's lone army is deep, and there have been many major battles in a row, and the combat power has been seriously depleted. In the end, he was taken advantage of by Guan Yi when his troops were at a disadvantage.

Yang'an Pass Resistance Battle, that is purely Guan Yi occupies the geographical advantage.

Therefore, until today, Sima Wang did not know until he saw the spearmen of the Shu Han army. He still underestimated the young man opposite.

At this time, Li Fu, the former enemy commander of the first line of the Jin army, was not a mediocre general. After seeing the strength of the Shu Han army's spear array, he quickly issued the order to form a shield array and then try his best to defend it. But even so, the first-line soldiers of the Jin army were still beaten back again and again.

The battle between the two sides began at two o'clock in the afternoon, and before two o'clock, the 10,000 Jin army forwards, their formations were already beginning to loosen.

"I see, Deng Shizai was unjustly defeated." As an experienced general, although Sima Wang frowned a little at the slow defeat of his own party's first formation, he was not too panicked: "Order, let Zhan Qing and Ju An attack!" ”

"Whoa!"

With Sima Wang's order, the ground of the entire battlefield began to shake violently. At this time, there was no need for Guan Yi to give an order, and Zhao Yi and Xian Hong also began to lead the cavalry of Shu Han to charge against the cavalry of the Jin State.

However, after both sides entered the visual range of the other party's naked eye, the leading Zhan Qing and Ju An found that the cavalry of the Shu army on the opposite side was a little different from the cavalry of their own side.

Yes, after having enough cavalry, Guan Yi completely lifted the ban on his own stirrups!

Now that the stirrup ban has been lifted, the cavalry spears that were previously standard for cavalry have all been replaced with sabers.

The stirrup was undoubtedly a revolutionary piece of equipment for cavalry. His greatest contribution is mainly twofold: first, the knight has a place to borrow on the horse. In this way, when attacking the enemy, you can use all your strength without preventing the embarrassment of using too much force and falling off the horse first if you are not careful. Secondly, with the stirrup, the knight's attack range is no longer limited to directly in front of him, but the attack range behind his side is more advantageous than directly in front of him!

There were no stirrups before, and everyone's attack range was relatively limited, so the spear was the best weapon. And now with stirrups, the range of cavalry attacks has been greatly increased, and of course sabers can appear - after all, when cavalry finally appeared on the battlefield in large numbers (World War I), the cavalry of all the powers was already saber cavalry.

(Well, it seems that during World War II, Poland used formed cavalry to attack the armored corps of the German three...... That's the swan song of the formed cavalry, right? ）

Therefore, when the cavalry led by Zhan Qing and Ju An began to put the spears in their hands flat, the cavalry led by Zhao Yi and Xian Hong drew out their long sabers in unison, and then raised the right hand holding the knife to the back of the shoulder, and rushed straight up.

The width of the battlefield consisting of 20,000 cavalry on both sides is so great. In an instant, when the horses of the two armies collided fiercely. Countless screams, horse roars, and the sound of knives and guns sounded one after another.

After rushing into the enemy's cavalry array, Zhan Qing and Ju An immediately felt the power of the opponent's sabre cavalry.

When the two horses were charging head-on, the opponent's cavalry focused on dodging the enemy's spearhead, but the moment the cavalry of the other side staggered past the opponent in the high-speed gallop of the war horse, the opponent's saber was fiercely chopped down.

After the two sides completed the mutual chisel, Zhan Qing and Ju An turned their horses' heads and took a rough look at their own array, and they were already frightened: there were not many cavalry on their own side, and even seemed to be a little less than the number of fallen horses of the other side. But the two leading generals knew very well in their hearts: the soldiers who were still on horseback on their side were probably quite few uninjured! Not to mention anything else, Zhan Qing's left hand was about to be cut off, and a large piece of the battle armor on his shoulder was chopped off, revealing Bai Sensen's bones below. And Ju'an's back and right hand and upper arm were slashed, and although there were no bones to be seen, a large amount of blood gushed out.

After the two generals glanced at each other, they nodded in tacit understanding. Then start to lead your own cavalry charge again!

"National prestige! Later, you will rush for your uncle first, and you will lead the people and horses of your headquarters to retreat to the north for at least twenty zhang! ”

After hurriedly explaining this sentence, Xianhong led half of his cavalry and began to hedge against the Jin army. Once again, the two sides collided quickly.

After this mutual chisel, the proportion of Jin cavalry falling off their horses increased at a very fast speed: it was possible to rush once, and take one or two swords without falling off their horses. What about being stabbed three or four times twice?

Fortunately, Zhan Qing and Ju An had already predicted this situation. When the two sides once again completed the mutual gouging, the Jin cavalry returned to the east flank. The two generals didn't look back at all, and directly took the rest of the cavalry and began to retreat in the direction of Chang'an in the east!

However, they have such a prediction, and the old Zhan Hong has the same prediction. His troops are now back to the west, but Zhao Yi's troops are now on the north side. So, when Zhan Qing and Ju'an began to retreat from west to east with the Jin cavalry, Zhao Yi's cavalry inserted strongly from the north side, cutting the Jin cavalry into two at once!
