The Lake Bandits will use ten thousand people to attack Yu Gan this time. It seems that they already know how to organize team training and prepare for war.
"Liaohuazi is not stupid. He didn't hit the ground directly. He actually came up with the idea of attacking from both sides and advancing both by land and water." Li Dan sneered: "Especially since he waited patiently for the various parties in Huxi to agree to send troops, this shows that he There is also a place for caution.”
"The intensified conflict between Bailang and Finless Porpoise allowed him to let go south. It seems that he actually doesn't trust those two families very much." Han An said: "Two of the three major lake bandits have not come, so we can be more relaxed."
Li Dan looked at Zhao Jingzi, who was frowning and thinking, and asked with a smile: "What do Xianfu think? Is there any good strategy for defeating the enemy?"
"I can't speak of a good strategy." Zhao Jingzi shook his head: "I was thinking that if the enemies from two areas gather at the city, we may have a hard time, but if we can defeat one group first, and then attack the other group with all our strength, that would be much better. !」
"How can the enemy be so obedient and listen to your orders?" Senior Master Ba winked teasingly: "But I guess the two routes are so far apart that there must be poor communication. Maybe we can make a fuss about it?"
"Well, that's a good idea!" Han An nodded in agreement.
"A long distance apart...? Then there are several possibilities: either the two sides cannot be in sync, or the news is difficult to distinguish between true and false, or one side has already taken action while the other side is still in the dark."
Li Dan looked at the crowd with inspiration: "It would be very interesting if these situations happened at the same time."
Zhao Jingzi jumped up, ran to the map, looked at it, and said, "I have an idea. Let's figure out how to lure the navy in the west to a suitable place, and then annihilate it in one fell swoop!
Just like how we first defeated the enemies of Dayuan Village in Guangxin, and then dealt with Yin Tuo with all our strength. "
"Then why is it West Road?" Li Dan asked with a smile.
"There are few troops on the west route, and according to the intelligence, it is a joint force of several lake bandits. The command must be inconsistent, and they may not be convinced by each other. In short, they are a weak army and easy to bully.
Furthermore, traveling on water should be faster than traveling on land. We beat it on the way, and it will take several days before the east side gets the news. By then we will have already withdrawn our troops from the river.
Also, the purpose of sending their navy is to encircle Yugan. I think the lake bandits probably don’t know that we also have a navy hidden in Lake Bipa, right? "He finished in one breath, look at this, look at that.
At this time, everyone was thinking, and no one even moved when Mao Zaidi and his soldiers brought breakfast.
"I think what Xianfu said makes sense." Han An expressed his opinion first. Zhao Jingzi laughed obviously with relief. As long as Mr. Han agreed, he felt that Li Dan would definitely have no objection.
"There is no problem with the logic. There are only two things: where to set up an ambush and who will go there?" Sure enough, Li Dan shifted his attention from the map to Zhao Jingzi: "Has Xianfu thought about how to do it specifically?"
Zhao Jingzi rolled his eyes and blinked: "What do you think about placing the battlefield in Santang?" He said, placing his two hands on the location of Santang on the map, moving them up and down, then closing them and holding them together. .
Li Dan immediately understood what he was thinking. There is a fortress built in Santang, and there is a lake called Nanhu in the southeast.
The Santang River made two turns here, forming a large sandbank outside Nanhu called Nanhuzhou, two miles long from north to south and four hundred paces from east to west. Santangbaozhai is on the left bank of the river, and the right bank is opposite Sanjia Lane.
Li Dan visited this place when it was designated for the inspection branch and the district team office. He recalled the terrain in that area and nodded slowly with a smile: "This is a good place for an ambush. So, what do we want to do next? Thinking about it, what method can be used to trick the lake bandits?"
Whenever he encounters any problem, Li Dan always likes to go to Chen Gang's shop.
Look at the construction of new carriages, discuss what the "leverage principle" is, and teach Chen Sanwen how to calculate oblique angles, side lengths and areas using Arabic numerals. But today he just sat on the steps and thought, and never spoke.
Chen Sanwen was afraid that he might hold it back, so he walked over and sat down side by side with him and said, "Sanlang, the bearing parts you mentioned last time are all ready, but I tried several times without success. The beads can't be put in." ? Do you have any good ideas?"
Li Dan seemed to be awakened, glanced at him, stood up, patted himself and said, "Where are the things? Bring me a thin quilt!"
Chen Sanwen didn't know what the relationship was between the quilt and the bearing, but he immediately followed the instructions. Li Dan picked up the bearing parts and looked at them, nodded and said, "It's polished very smooth, but you're using the animal-powered grinder I taught you?"
"No, it only took a little donkey to polish it like this. No one else can imitate it!" Chen Sanwen said proudly.
"Don't underestimate people in the world. There are smart people. You can hide it for a while but you can't hide it forever." Li Dan smiled: "When we have water-powered grinders and wind-powered grinders, you can sell these animal-powered ones.
But before that, the animal-powered grinder can actually be updated, and there are many options to make it more convenient, lighter, or more efficient. "
He kept talking without stopping.
Place the inner and outer rings on the quilt, pinch them together with one hand, and then place the steel beads on the side with the larger gap. Then slowly push the inner ring upwards, and use a nail on the table to spread the beads evenly. Put on the support bracket and close the dust cover with a click.
Li Dan turned it over and put it on the table: "Now you weld the support bracket on this side and put the dust cover on it, and it will be ready for use."
"But... why did you ask me to get a quilt?" Chen Salmon was confused.
“Placing heavy objects on the quilt will create dents or bulges, which is key.
There are protrusions on the quilt between the inner and outer rings, which help the beads to align with the inner concave of the outer ring and the outer concave of the inner ring. The inner ring is slowly pushed up, and the beads are in the middle of the two rings.
But the beads are not yet stable at this time, and support brackets are needed to assist and fix them, and then a dust cover is added so that the beads will not overflow due to the pressure of the axial load... "
Li Dan's detailed explanation helped Chen Sanwen not only understand the method of placing beads, but also understand the question that had been bothering him: Why do I have to add a dust cover?
"This thing is really good!" He was having fun playing with the installed bearing. "Saburo, with this thing, the carriage can run faster, right?"
"It's more than just a carriage?" Li Dan temporarily put aside what was on his mind and told him with a smile:
"Try to match it with the gear in the steering gear. With this thing, the axles everywhere in the car will be very smooth, and it will no longer scream so loud." After saying this, he was stunned for a moment and looked down at the table for a long time. Suddenly he whispered: "Bring a pen and paper."
Chen Sanwen knew that he had another idea, so he quickly went to get the leather paper and pencil from his desk, and then looked at Li Dan's drawings, his eyes widening as he watched. "Saburo, this, is this a catapult? A horse-drawn catapult?" he shouted.
That's right, what Li Dan painted was a miniature version of a four-horse carriage, with a four-wheeled trebuchet towed behind it.
The carriage in front is smaller than a four-wheel carriage, only nine feet long. According to the explanation, it is a "projectile carriage."
The catapult at the back also uses a two-wheeled chassis of the same size. A wooden bar extends from the left and right sides of the rear frame of the catapult, and the iron hook at the end is hung on the steering gear of the catapult.
"Look, this is a projectile vehicle, and the one behind it is the launching vehicle. In addition to loading projectiles for throwing, the projectile vehicle can also have a driver and driver (referring to the person who maintains the vehicle, who can also replace the driver, and serve as auxiliary troops in war) and carry Four soldiers.
When the carriage arrives at the combat position, it immediately unhooks and puts down the launch vehicle. The driver opens the two auxiliary hoes under the steering gear of the launch vehicle and nails them to the ground to secure the vehicle;
The rest of the people hung the counterweight on the throwing arm, and then one person directed the driver and the driver to help adjust the direction. The two shook the handle to drive the gear, and the force arm pulled the throwing rod to lower it, and the projectile was put in.
After the commander issues the command, he must continue to drive the gear, move the chuck to the release position, re-open the folded force arm, and the throwing rod will bounce upward under the action of the counterweight and throw the projectile.
In this way, only six people are needed to prepare and attack the catapult. "
"So, the catapult can be moved at any time?" Chen Salmon stroked his beard and his eyes flashed brightly.
"Yes, we can lay ambushes in the wild, attack the lake bandits on the river, or even make it smaller and bring it to the top of the city to throw grenades.
! "
"However..., judging from its appearance and size, I'm afraid it can't be thrown very far." Chen Salmon frowned.
"It doesn't need to be very far, just be able to throw within two hundred steps!"
"That's easy!" Chen Sanwen nodded: "Give me the manpower and wood, and make two hundred of them to beat that Polygonum Flower to death!"
"Not so much." Li Dan smiled, told him about preparing to ambush the enemy navy, and then told him:
"If you make thirty pieces, you will be a major contributor to this battle! I asked Xie Baozi to build Ishimaru in Mianshan. As for the wood...?"
He was still thinking, but Chen Sanwen already had an idea: "I suggest putting them all at Yujiadu. It is convenient for quarrying stone and logging from Yunshan Ridge. The important thing is that it is difficult for bandits to detect across the Donghe Lake.
The existing labor force in the charcoal field and lumber factory in Yujiadu can be used, and even the allocation of manpower is saved. After it was built, it was shipped directly from Yujiadu to the Santang River without anyone noticing! "
"Good idea, let's do it!" Li Dan was happy. There have been two problems in this battle: which troops to send to the battle, and how to make up for the team's lack of combat experience.
Now that there is a flexible catapult, the latter can be compensated to a large extent with the support of strike weapons, so he is very happy. An idea struck, and he proposed that the trebuchet could be installed on a slightly larger warship.
"Remove the watertight compartment, lay ship planks in the bottom compartment, add axles and oars, and move them manually. There is a cabin in the middle of the upper deck. There are two trebuchets on the front deck and one on the aft deck. There are two small machines on the cabin. "
Li Dan started thinking. He drew one picture after another, telling Chen Salmon how to combine the trebuchet with the gear to adjust the direction and pitch angle.
In addition, he proposed that Zhou Qin transfer some of the shipbuilding craftsmen from Pipa Lake to Yujiadu, and notify the ancient port to urgently dispatch 800 laborers for Chen Sanwen's use.
"But... you'd better not go to Yujiadu in person. Is there anyone you can send?" Li Dan asked him.
"What do you think of Tang Kai, the guy who went to Shangrao with me last time?" Chen Sanwen recommended: "His family used to be a big shipbuilder, and his father is now at the Pipa Lake Dockyard."
"A family of craftsmen? That's great!" Li Dan immediately agreed to appoint him as the deputy envoy of the Tuan Lianqi Bureau (the envoy was Chen Sanwen), and asked him to be fully responsible for the supervision of Yujiadu.
"Two major issues have finally been solved!" Li Dan said happily.
"What's the other thing?" Chen Sanwen thought it was related to utensils, so he asked.
"Well, you are not an outsider either. In fact, you just haven't made up your mind about who to send to fight this ambush." Li Dan smiled bitterly.
It turns out that Gu Da, Yang Yi, Shen Jie, Zhang Bo, and Liu Hongsheng are all training troops now. Each of them has three hundred subordinates and they can't do it without training. Zhou Qin's sailors will definitely be dispatched this time, and three other teams will be needed to cooperate.
Although Tan Zhongxiao's number has increased to 500, the proportion of veterans in his team is actually the highest. This time he must be ambushing on the sandbank to fight a tough battle.
One of the other two groups is responsible for ambushing in Sanjia Lane, and the other is responsible for ambushing near Huweitang. After receiving the signal, it is responsible for intercepting and killing the enemy's boats at the rear or turning around and escaping.
It doesn't matter if the former fights on the shore, Yang Yi has already been chosen, but the latter may have to go on the ship. It is difficult to decide on this candidate, because Li Dan knows that the water skills of those few are average.
Not wanting to talk to Chen Salmon, he suddenly laughed and criticized: "I said you are such a noble person who forgets things!"
"Ah? How did you say this?" Li Dan was confused.
"I remember that Yang Lianjie was also from a Shuishui family, right?"
"Oh! How could I forget him!" Li Dan stumbled and shouted as if he had just woken up from a dream.
But no, Yang Dayi's family is a ferryman. He grew up by the river, how could he not be familiar with water properties? It seems that the traditional concept of northerners not being good at water warfare is at fault. Li Dan slapped his forehead repeatedly, feeling ashamed in his heart.
In the county jail, an officer wearing a buttoned Tsing Yi half-length gown with a red horizontal stripe on his left arm said something to the prison guard who was holding the key.
The latter nodded and stared at the white patch on the other person's left chest.
The word "Zhenfu" was written on it, and he said enviously:
"Oh, Xie San'er, I didn't expect that your boy has become a flag officer now, and I have become an errand for you. Ten years to the east of Hedong, ten years to the west of Hexi!"
Xie Saner smiled and did not answer the question. He was the governor who had detained Wang Xi, and was now promoted to be Zhong Siqi's deputy.
I remember that before he came to Liu Er's house as a clerk, he had been imprisoned for participating in a fight, and this was the cell leader at that time.
Old acquaintance! But today he is not here to reminisce about old times, but has a very special mission.
"Wow!", the prison guard unlocked the door chain, covered his nose and shouted: "Hey, boy, come out to the court!"
An expressionless man came out of the smelly breath and shadows. He looked up at Xie San'er, who was holding a knife on his hip, and said softly: "Sir, I have told you everything I know, really!"
"Come out and talk, I don't want to stay in such a dirty place for too long." Xie San'er walked a few steps, turned around and saw that he was still hesitating, and said, "If you don't want to go out and see the sunshine, go back to the prison." Squat down, I don’t have time to wait for you!”
After hearing this, the man quickly followed him, as if he was afraid that the prison boss would push him back into the dark cell again.
