Daqin Engineering Corps

The main reason is that the Huns fled as soon as the countries in the Central Plains sent troops. The countries only thought that they had won, so they didn't realize the power of this tactic at all.

This situation lasted throughout the Qin Dynasty. When Liu Bang became emperor, he was confident that he could easily defeat the Xiongnu, but the result was surprising.

At this time, Shen Bing demonstrated this tactic completely.

So Xiang Yan exclaimed: there is such a strategy?

Xiang Yan didn't take this too seriously at the beginning, because the only information he received was that Xiang Luo had lost two battles, and both battles were fought when there were only more than [-] people from the Xiang Luo Department.

Xiang Yan took it for granted that Xiang Luo also had shortcomings in command, otherwise how could more than [-] people come forward to fight the enemy in batches.

Thinking about it this way, although the tactics of the Black Armored Army are formidable, if there are more Chu troops, I am afraid that the three thousand Black Armored Army will not be of much use.

However, that night, Xiang Luo asked the courier to send another letter:

"Our troops have withdrawn to the east bank of Rushui, and there are less than two thousand survivors."

"The Black Armored Army is extremely fierce, and the cavalry army must not fight against it!"

Only then did Xiang Yan realize the seriousness of the situation.

When 2000 cavalry went out, only less than [-] returned, and it was only a day before and after, and only the [-] black armored troops faced off...

How many casualties did the Black Armor Army have?

Xiang Yan had no way of getting it, because Xiang Luo didn't mention it in the letter.

But Xiang Yan thought about it again, if the Heijia army used cavalry and shooting tactics throughout the whole process, and Chu Qi's bow and crossbow could do nothing to it, the casualties of the Heijia army would be very few.

This……

Xiang Yan frowned and turned her gaze to the map, thinking to herself that fortunately, her cavalry had already captured the city and built up defenses, so there was no need to fight.

So if the black armor army came, I'm afraid there was nothing they could do.

But after thinking about it, I felt wrong, how could the cavalry not fight?

If the cavalry does not fight, how is it different from the infantry?

And what if the Heijia army attacked the infantry instead of the city?

Infantry...Infantry can build a shield wall and can shoot back with crossbow arrows, this method of warfare may not be effective against infantry.

Of course, this is just Xiang Yan's wishful thinking. In fact, cavalry and shooting will be another advantage as long as the tactics are used properly against infantry. The tactics of the Mongolian cavalry prove this.

However, since there is no stirrup at this time, you can only ride and shoot but not hack and charge, so the advantage will be weakened a lot.

Then Xiang Yan thought about it more carefully, and was instantly frightened into a cold sweat...

If the Heijia army does not attack the city and the infantry, but instead attacks the supply line, it will hit the weakness of the Chu army.

Didn't the Chu army just use the cavalry to cut off the supply line of the Mengwu army?

Why can't Hei Jia counterattack the supply line of the Chu army?

At that time, the black armor army will face the supply team, so how can it be its opponent? !

At that time, should Chu Qi reinforce or not reinforce?

If it is reinforcements, his [-] cavalry army may be the second in the Xiangluo Department.

If there is no reinforcement, the food road will be cut off, and the Chu army will be surrounded by the Heijia army, Mengwu army, and Daliang army instead.

Xiang Yan was at a loss for what to do for a while, and walked around in the tent, not knowing how to deal with it.

This is a kind of arms advantage.

The reason why there are these arms on the battlefield has its own reasons, and they are developed by all countries through blood and life lessons on the battlefield.

For example, chariots can attack and defend, and can charge in flat areas.

The Bishi Cavalry can quickly maneuver to respond to unexpected battle situations.

Infantry is the best choice for siege.

These arms can be weak, but not without.

Because once a certain branch is not developed at all, there will be unsolvable loopholes in combat and the enemy will take advantage of it.

There was no problem with the Chu army having these arms.

The problem is that as soon as the black armor army came out, the cavalry troops of the Chu army were no longer "weak", but could almost ignore their thinking and regard them as "none".

Therefore, in the field of cavalry, the Heijia army can do whatever they want and give full play to the advantages of the cavalry to suppress the Chu army.

Then Xiang Yan faced a difficult choice: to protect the supply line or send the cavalry to die?

If sending the cavalry to die was useful, Xiang Yan might still choose this option.

Because after all, this can solve the crisis of Chu State.

However, after the cavalry died?

The supply line is still going to be broken, so how can we fight this battle?

In the end, Xiang Yan could only grit her teeth and ordered:

"Withdraw the troops and return to Master City Father!"

Chapter 222 Chasing the Enemy

Xiang Yan's order made his subordinates a little confused.

Even Uncle Xiang didn't understand, he hurried to the commander-in-chief and asked:

"General, our army has already cut off the Qin army's food route and forced them to retreat. Why are we retreating at this time?"

Xiang Yan didn't speak, but just shook her head at the information on the desk.

Xiang Yan actually wanted to test Xiang Bo to see if he could make the same inferences as herself from the intelligence.

But Xiang Yan was disappointed, Xiang Bo only glanced at the information, and then said bitterly:

"Xiang Luo is hateful, he keeps saying that he will block the Qin army, but he doesn't want to be so powerless!"

"The [-] cavalry army was defeated by the [-] black armored army!"

Then Xiang Bo changed the topic again and said:

"General, even if Xiang Luo is defeated, our army will not retreat."

"The Qin army came to aid only [-] Liang troops."

"It's just right here, I'll surround them together!"

Xiang Yan glared at Uncle Xiang angrily, hummed, and didn't bother to explain, only replied:

"No need to say too much, just go down and prepare!"

Uncle Xiang wanted to say something but was stopped by Xiang Yan's eyes, so he didn't dare to talk too much and bowed his hands before retreating.

Looking at Uncle Xiang's back, Xiang Yan couldn't help but sighed, thinking to himself how could this uncle be so short-sighted in the future, how could he take on such a big responsibility?

This is also the reason why Xiang Yan let Xiang Liang lead the army alone, but Xiang Bo has been by his side all the time.

Although the two sons have followed Xiang Yan for many years, they are far apart: Xiang Liang is cautious and considerate, while Xiang Bo is short-sighted and short-sighted, and he doesn't know when he will be able to make great use of it.

What Xiang Yan didn't know was that in the future, Mr. Xiang would live better and live longer.

Twenty years later, Xiang Liang rose up and led troops against Qin, and was finally defeated and died in Dingtao.

Xiang Bo was bought by Liu Bang, and rescued Liu Bang from Xiang Yu again and again, and was later given the surname Liu by Liu Bang as the Marquis of Sheyang.

If Xiang Yan knew this, he might be so angry that he would chop Xiang Bo off with a sword.

Not to mention that Xiang Yan was puzzled, even his opponent, Meng Wu, was also surprised when he heard that the Chu army had withdrawn to Chengfu.

The Chu army had clearly gained the upper hand. As long as they continued to control those fortresses, the tens of thousands of Qin troops would have to retreat to Rushui.

At that time, Rushui will also be short of food and grass... A supply line cannot support the battle of two armies, and the supply line is still exposed to the front of the Chu army.

This is also the reason why the Qin army had to divide its troops into two groups to attack Rushui and Chengfu respectively.

It is not impossible to concentrate all the troops to attack Rushui, but the Qin army goes deep into the Chu territory to fight. Attacking only one place will make the Qin army's offensive route as if going straight to the enemy on three sides, and it is very easy to be surrounded by the Chu army.

And if the two armies are separated by two hundred miles and attack at the same time, not only can the two armies respond to each other and support each other, but also create a safe area in the middle for logistics and supply operations. At most, the two armies only need to deal with enemies on both sides.

Therefore, once the Mengwu army was defeated, Yang Duanhe's army in Rushui was helpless and had no choice but to withdraw.

However, when the Mengwu army retreated all the way south, the Chu army interspersed and occupied the rear supply area, but the Chu army retreated? !

Meng Wu said to himself:

"Could this be a trap set by Xiang Yan?"

The minister said:

"General, maybe it's because the Daliang army came to help..."

Before the general could finish speaking, Meng Wu interrupted him and said:

"Da Liang's army only has more than [-] people, and they haven't fought yet. Do you think they are divine soldiers and generals, so they can scare away the Chu army?"

The general even claimed it was, and couldn't help but say after a while:

"It is said that the Daliang Army defeated the Chu Army in Ruanqiao Town..."

Meng Wu replied without thinking:

"More than [-] men defeated [-] Chu troops, how can it be called a big defeat?"

No wonder Meng Wu would think so.

The information Shen Bing sent to Meng Wu was an understatement and a general description of the situation.

It is impossible for him to say how the Black Armored Army defeated more with less and what tactics they used... If he said so, it would be blatantly showing off.

So Meng Wu didn't know as much as Xiang Yan.

So the Mengwu army retreated and could not advance.

Retreat, the Chu army has already withdrawn, and retreating south will make Daliang army laugh at it?

After entering, I was worried that this was Xiang Yan's trick, and I fell into the pit as soon as I entered.

Just when Meng Wu was hesitating, he heard the spies come into the camp and shout excitedly:

"General, reinforcements have arrived, and it is the Black Armored Army!"

When Meng Wu walked out of the tent, he saw that there was already thunderous cheers outside, and soldiers of the Qin army kept waving their hands in the distance.

Meng Wu followed the soldier's gaze, and sure enough, he saw a mass of black cavalry riding their horses a mile away. Who else could there be if it wasn't the Black Armored Army?

The Heijia army was getting closer and closer, and the sound of horseshoes became louder and louder.

Meng Wu thought that the Heijia Army would stop and join him, but he didn't want it to bypass the Qin Army's camp and continue northward.

When Meng Wu was wondering, he saw two riders riding their horses into the camp. The riders skillfully reined in their horses and stopped, then jumped off their horses and ran in front of Meng Wu, reporting:

"General, this subordinate came here to plead guilty under the order of the school lieutenant."

"The battle situation is urgent. The captain is leading the army to chase the enemy. We will meet in the future. Please forgive me, general."

After the report was over, the two riders hurriedly got on their horses and chased after the large army, as if they were worried that the Chu army would run too fast and would not be able to catch up.

Only Meng Wujun and the others were left stunned.

What's the situation?

At least Xiang Yan's army has more than [-] people, how dare the [-] horsemen of the Black Armored Army come forward to chase and kill them?

Is this too long?

It took Meng Wu a while to react.

This can't be done!

He still has [-] men under Meng Wu... During this time, Meng Wu attacked the city and Rushui again, and then was chased and killed by the Chu army.

The [-] black armored troops have the courage to pursue the Chu army. How can I, Meng Wu, lead a [-] army and just stay here in a daze?Still worried about whether it is the enemy's trap and dare not chase the enemy?

So without thinking too much, Meng Wu immediately ordered the army to go north to chase the enemy.

After the army was launched, Meng Wu also said to the general:
