"As for Sun Di and Zhao Qing...... Let them fight first, and remember, if the enemy sticks up, retreat immediately, and all the supplies and ammunition can be returned by rail as quickly as possible. ”

Ye Yu ordered, he still hoped that Sun Di and Zhao Qing would be flexible.

So the orders are quite flexible, and if they can deal with them, they don't need to do this series of actions on their own.

But if they can't cope with it, they will be defeated for a while, and if they don't prepare the retreat line in advance, I'm afraid that the Southern Dynasty will be gone.

"Yes!"

Zhang Ye immediately sent someone to issue an order.

"Your Highness, the minister is back."

Zhang Xingbang had just returned from the front line with a sweaty head, "According to the investigation of the secret guards, they should really dig trenches now, from the front line of Lincheng and Yangcheng. ”

"Sure enough, they came up with a solution."

Ye Yu said with a frown, "In this way, the distance between their army and the river and the city wall will be shortened. ”

"Yes, Your Highness, do you want to let Sun Di and Zhao Qing withdraw?"

Zhang Xingbang thought about it and said, "If they are rushed up, it is estimated that it will be difficult for them to react." ”

"No, I choose to believe them."

Ye Yu opened his mouth and said, "You first withdraw the people, tell Sun Di and Zhao Qing the corresponding information, and then behind the city wall, set up the intelligence network and prepare to fight a defensive battle." ”

The demilitarized zone is flanked on both sides by a river and large plains.

If you really want to fight, there are enough people charging head-on, the formation is scattered enough, and there is nothing to do with heavy machine guns.

The main thing is that there are really few people in their hands now!

He really wanted Sun Di and Zhao Qing to withdraw the corps, but ...... He always had luck in his mind.

Sun Di and Zhao Qing are not stupid, after such a long time of training in the military academy, they should be able to learn to be flexible.

Soon, Yang Jiang's headquarters began to retreat, and they all withdrew from the mountains, after a day and a night of movement.

They had come to the edge of the station.

It is the only railway from South River City to the border of the Demilitarized Zone.

At the same time, Zhang Detian's people also came up.

"Your Highness, the reserve has prepared six regiments of six thousand people, and the rest are still training, and the first batch of supplies has been delivered."

Zhang Detian slowly spoke after arriving at the station.

"Very good, let your people build the direction with Yang Jiang, and send more materials."

Ye Yu nodded, and then took Ye Xiong to build a new headquarters together.

The new headquarters, placed thirty meters behind the station, has a railway, which makes it possible to quickly know the news before and after.

In a moment, Yang Jiang and Zhang Detian had already arrived at the command headquarters.

On the table, a sand table was also prepared.

"Report to Your Highness, the soldiers of the First Corps are still continuing to build a defensive line, and the barracks are almost ready, but it will take some time to complete the defensive line."

Yang Jiang reported.

"Okay, let Zhang Ye come over too."

Ye Yu saw that the headquarters had been completed, so he asked Zhang Ye to come in.

After all, he is now the only designated herald in the military.

The heralds saved were either used to fill the troops or to be used as reserves.

It didn't take long for Mr. Zhang Detian, Yang Jiang, Ye Yu, Ye Xiong and Mr. Wen Zhu to be in the headquarters.

"Temple...... Your Highness! ”

Although Ye Xiong had a disguise, Zhang Detian, as a veteran, still saw Ye Xiong's eyes.

"It's a secret, so it's not there."

Ye Yu frowned slightly, Zhang Detian nodded, and saluted Ye Xiong slightly.

"Your Highness, here."

"According to Zhang Xingbang's report, Ye Lie's army is still digging trenches, and at their speed, it is estimated that they will be able to come to the river the night after tomorrow."

After Zhang Ye came in, he told everyone the information.

"Okay, I didn't let Zhang Xingbang continue to monitor them."

Ye Yu nodded.

"Why didn't His Highness let Sun Di and Zhao Qing retreat?"

Zhang Ye immediately spoke, "If they stick to the river, I'm afraid it will be difficult to fight." ”

"They're supposed to leave, but I need them to buy us time."

Ye Yu's eyes were quite serious, "If there is no defense, they rush in like this, we won't have time to establish a defensive line." ”

He sighed as he spoke.

"Yes!"

Zhang Ye just wanted to leave, but was stopped by Ye Yu.

"You stay, and then it's a strategic approach for the rest of the day."

"I want you to listen too."

Ye Yu spoke, and then began to arrange.

"Okay, now let's assume that Zhao Qing and Sun Di can't bear it and retreat. This is their strategic plan after retreat. ”

He spoke slowly, "First of all, receive the retreating rout troops from Sun Di and Zhao Qing, and reorganize and replenish them as quickly as possible." ”

"Second, the artillery is concentrated in this position, and it is enough to radiate to the Nanhe River behind the city wall."

Ye Yu said, pointing to their rear, "Concentrate the position, and the artillery will cover them intensively." ”

"Thirdly, the machine guns on the position should be put away, the period after that is very critical This line is too long, and the machine gun is a decisive defensive weapon."

"Finally, Yang Jiang, draw two for me and cooperate with me to prepare a counterattack."

After that, Ye Yu looked at everyone, "I need everyone to understand that this battle is not commanded by me alone, all variables, all battles, I need all of you, including every soldier of the Southern Dynasty, to take the initiative." ”

"Yes!"

Everyone spoke in unison, and then quickly began to prepare.

Time passed little by little, and the retreat line of defense made a certain foundation.

The time also came to the day of the attack mentioned in Ye Lie's text.

At this time, Ye Lie's army, including Ye Lie himself, had already come to the front line of trenches.

Ye Lie poked his head out slightly, and he could see that the river on the border line that was used as a dividing line was close at hand.

"Push the chariot up and drive into the river!"

Ye Lie ordered, "After entering the river, jump out of the car and use this as a springboard for attack!" ”

He knew that these chariots could not be protected, but fortunately, they were made of wood and could float on the river, so they could be turned into improvised boats or even pontoons!

"Longbowman, prepare!"

Across a river, it was exactly the range of the longbowmen.

The tens of thousands of longbowmen in Ye Lie's hands are all in a state of readiness at this moment.

In the trenches, warp shooting has a huge advantage.

Including Ye Lie, all the longbowmen drew their bows.

"Put!"

Ye Lie gave an order, and all the arrows flew out!

Although Sun Di was prepared, he kept staring at these people.

But he never thought that Ye Lie would choose to use a bow and arrow to shoot!

"Behind the wall!"

"Re-establish the line of defense!"

Sun Di frowned, he knew that Ye Lie's army in the trenches was wasting bullets by hitting his machine guns and rifles.

Even if they can do a certain amount of damage, they can't stop their attack.

But the order was passed down a little late, and many of the soldiers in the trenches in front of the city wall were shot directly into hedgehogs before they had time to retreat.

Zhao Qing also faced the same situation here, in the face of the bow and arrow, they had no way!

It was only possible to retreat behind the walls to make a defensive line, and at the same time they began to prepare artillery.
