"Absolutely......" Wei Zheng replied confidently.

After drawing a schematic diagram of the trench and retaining wall on the ground with a branch in his hand, Wei Zheng, with a confident face, patiently explained as if a teacher was teaching a student.

"You see, this is a three-foot-high retaining wall, and it can also serve as a breastwork for our first line of defense, using this earthen wall as a cover to shoot as many Tartar cavalry attacking us as possible with muskets and artillery."

"When the Tartar cavalry rushed fifty meters away, the soldiers defending the first line of retaining walls immediately retreated along the communication trench to the second trench or retaining wall under the cover of shields."

Seeing the confused expressions on the faces of the two of them again because of the words 'traffic trench', Wei Zheng continued to explain.

"What I mean by 'communication trench' is not something complicated, but a trench that connects the front and rear trenches and the retaining wall. The trench only needs to be dug two to three feet wide, but it must be dug to a depth of one person. Only in this way could the soldiers retreat along the trenches and hide themselves completely from the Tartar archers. ”

"As soon as we withdraw from the first retaining wall, the Tartar cavalry will have to face directly the line we have just abandoned."

"What do you think the arrogant Tartar cavalry will do with the retaining wall more than three feet high in front of the Tartar cavalry?"

"Just jump over the prancing horse and ......" Zhou Shuyuan, the military advisor, didn't think about it, so he interjected and replied.

Wei Zheng nodded in agreement, and after a pair of eyes quickly shot out two rays of light, he replied with a deep face: "Yes, it's the prancing horse jumping over." And all I want is a Tartar prancing horse to jump over this retaining wall. ”

As he spoke, Wei Zheng had already picked up a branch and drew an arc on the section of the retaining wall, representing a schematic diagram of the Tartar cavalry jumping over the retaining wall.

Then, pointing to the arc opening, he analyzed: "As far as I know, the distance of a jump of the Tartar cavalry can reach five meters in the process of sprinting with all its might. Then let's calculate it in terms of five meters. ”

"When the Tartar cavalry jumps two meters from the retaining wall and crosses the three-foot-high retaining wall, it will fly forward at least two or three meters before it can land."

"If you take a good look at the section on the ground, what is the distance of two to three meters behind the retaining wall?"

Military advisor Zhou Shuyuan reacted first, and replied excitedly: "It's a trench, a trench three feet deep and three meters wide. ”

Speaking of this, a picture full of blood had already surfaced in Zhou Shuyuan's mind, and he said to himself: "General, according to what you just imagined, after the Tartar cavalry fell into the trench, if you are lucky, you may be able to leave a life. ”

"If you're not particularly lucky, you'll hit the three-foot-deep earthen wall of the trench. No matter how thick the iron armor is worn on the Tartar for protection, it will also be thrown out by the war horse and thrown into a pile of meat on the ground. ”

Inspired by Zhou Shuyuan, Wang Feng followed suit and added: "General, we can also insert a row of barbs made of logs in the trench. As soon as the Tartar cavalry fell into the trench, they would stick to the barbs and be either killed or wounded......"

"You are all right, with such a trench, we can at least kill and wound dozens of Tartar cavalry before the Tartar attacking troops can react, and if we are lucky, with the help of firearms, it is not impossible to kill and injure hundreds of Tartar cavalry."

At this moment, Zhou Shuyuan's brows, which had just relaxed, furrowed again.

He reminded Wei Zheng: "But, general, although the kind of dispatch you said is good, it can only be used once. The Tartar cavalry who was in charge once will definitely not go a second time. ”

"From what I know about the Tartars, the Tartar cavalry who launched a second attack will definitely use the retaining wall we have built as a cover to drive the infantry to destroy the retaining wall and fill the trench we have worked so hard to build."

"When the time comes, the Tartar cavalry will be able to continue the attack on us."

Wei Zheng shook his head and signaled Zhou Shuyuan not to worry.

"I've already considered this concern of yours, and that's why I'm building a group of trenches outside the Mushroom Valley instead of a separate one. ”

"The Tartars have broken through the first line of trenches, and we have a second, and even a third."

"What's more, we keep the spacing of each of our trenches at a distance of about a hundred paces, and ordinary Tartar archers cannot shoot us from a distance with their bows and arrows, but the new arquebuses we have just equipped can shoot Tartars a hundred paces away with Minnie bullets."

After speaking, Wei Zheng directly led the two of them to climb the city wall that had been built to a height of three meters.

Looking in the direction of Wei Zheng's finger, the only way to Mushroom Valley is like a long horn, clearly displayed in front of everyone.

This is, Wei Zheng continued to analyze in a guiding manner: "You see, the trumpet-shaped terrain in front of us is two miles long, the widest place is about a hundred steps, and the narrowest place is only less than fifty steps. It is safe to say that the terrain here seems to have been specially prepared for us, and it is very suitable for us to build trench groups on this land, to block the enemy in echelons, and to deplete the vital forces of the Tartar attacking troops little by little. ”

Seeing the thoughtful expressions slowly emerging on the faces of the two, Wei Zheng continued.

"In addition to trench groups, we can also insert a large number of rejecting horses between trenches that slow down the attack speed of war horses. The longer the Tartar cavalry spent on the road, the more lead bullets our musket battalions and artillery operations fired, and the more Tartars were shot. ”

"However, when building the rejecting horses, in order to prevent the Tartar cavalry from destroying them with horse sheaths, all the repulsive horses had to be buried deep in the ground to ensure that the Tartar cavalry could not destroy them lightly."

"The construction of so many trenches and horse rejection is absolutely impossible to complete in just two days with our current strength."

"So, we have to build the first two lines of defense. When the time comes, even if the Tartars come and attack us, we can continue to build a follow-up line while we block the attack. In addition, we can also draw some young men from the city wall to help without affecting the progress of the city wall. ”

"In addition, doesn't it take a lot of clay to build the city wall, and the excess clay we dig up from the construction of the trenches is the best material to fill the city wall."

"We can move the excavation team that built the wall to the battlefield and help us dig the trenches and repair the walls at the same time. In this way, not only will it not affect the progress of the construction of the city wall, but it will also speed up the construction of trench groups. ”

"My last opinion, although Director Liu, who is in charge of building the city wall, is not a soldier, after all, he has been building houses and city walls for decades, and he must have his own opinions and simple methods that we don't know when it comes to digging trenches and repairing earth walls. Therefore, immediately after going down, we went to find Director Liu and asked Director Liu to be our assistant to assist us in building the trench group. ”
