Huang Jun and Zhang Hong's words made Li Yan enlightened, yes, the main way of fighting after the army entered Ruzhou was definitely siege rather than field battle, and according to the historical description of Li Zicheng, "You are good at attacking, and you are good at fighting." ”

As for how the intrusive army, which lacks technical troops, became the best at attacking the city among the peasant armies, it is extremely scary to think about it.

In the history of the Ming Dynasty, Li Zicheng's tactics were recorded, every time the city was attacked, the soldiers were ordered to rush to the city wall in turn, each time they chiseled a brick and then came back, if there was a person who failed to get a brick and returned, he would be beheaded, and so on, like ants moving the city wall would gradually hollow out, and then cooperate to attack the city, and the city wall would collapse......

Such an account sounds rather absurd, but Li Yan can't confirm whether Li Zicheng will have other better ways to siege the city, and if this is the case, then the reserve army is a cannon fodder army in the true sense.

After thinking about it again and again, Li Yan stared at the spear on the desk, and suddenly said: "The spear is the head of all soldiers, the so-called one inch long and one inch strong, isn't it a pity to abandon it like this?" ”

Huang Jun and Zhang Hong were about to give advice when they heard this, after all, if they used spears to attack the city, they were really unpleasant.

Without waiting for them to speak, Li Yan stretched out two fingers, gestured horizontally in the middle of the spear, and then said: "Cut it off from here, so that the length of the spear can be cut in half, and this length is not a constraint on the cramped space on the city wall, right?" ”

Hearing this, Zhang Hong and Huang Jun both lowered their heads and thought carefully, and after a while, Huang Jun nodded first and said: "What Guan Jun said is true, if it is truncated from now on, then the spear can be used." ”

"However, if you do this, the spear will have no advantage at all" Zhang Hong shook his head and said: "The spear was originally long to dominate the enemy, but now that it has intercepted so much, isn't it that it is shorter and its drawbacks are promoted?" ”

The advantage of the spear over the sword mainly lies in two points, one is the length, the so-called one inch long and one inch strong, the distance of the spear can suppress the enemy at a relatively long distance, and it is naturally a big advantage over the sword that can only fight closely.

The second is his ability to pierce armor, in ancient times, heavy infantry was either hit with blunt objects, inflicting internal injuries, or stabbing with spears, which penetrated deeper and more deadly than slashes.

But at the end of the Ming Dynasty, the situation was different, because of the appearance of firearms, the proportion of heavy armor of the Ming army was greatly reduced, and the general sword was enough to deal with those armor, in this case, the piercing advantage of the spear gradually became less obvious, and its length advantage became more important.

This is why, in this era, from Western Europe to China to Japan, the length of the spear has become unusually long, and it has gradually changed from an active strike weapon to an auxiliary arm of the musketeer, becoming a kind of fence-like composition.

Now Li Yan wants to cut off the spear and turn him into a short spear, obviously he is a little short and avoids the long......

Li Yan shook his head when he heard this, and said: "I am naturally clear about Zhang Xuan's worries, although the spear is truncated, it is not completely without a length advantage, compared to the sword, gun, sword, and halberd, it still has a certain distance advantage......

"The length is no longer long, and if you hold a spear, it is difficult to hold a shield, and when attacking a city, the most important thing is defense, and heavy armor shields can not be ignored." Huang Jun said worriedly.

"We don't have heavy armor," Li Yan said helplessly: "Now that these practices are rights and interests, the situation of the reserve army is clear to you, and I have no choice but to do so." ”

Zhang Hong and Huang Jun naturally knew the situation of the preparation army, and when they heard Li Yan say this, they also nodded their heads in understanding.

"Of course, I don't just let the spearmen attack the city, the trick in between is actually another point." Li Yan said slowly.

"Where?"

"Tactical coordination." Li Yan said solemnly.

"What is tactical coordination?" Huang Jun and Zhang Hong obviously didn't know the meaning of this word, and they all looked at Li Yan suspiciously, they had been in the army for many years, and it was the first time they had heard such a novel word.

Li Yan naturally knew that this later word was quite novel to them, so he patiently explained it in words they could understand: "Do you two know about Qi Shaobao and the Mandarin Duck Array? ”

"Naturally, I know" Huang Jun nodded heavily: "Back then, Qi Shaobao guarded the border pass, so that the Tartars did not dare to go south, how could he not know it?" But although the Mandarin Duck Array has heard of it, it is not known specifically, does the Guanjun know about the Mandarin Duck Array? ”

Looking at Huang Jun's surprised eyes, Li Yan sighed helplessly and shook his head and said, "Alas, I watched the Mandarin Duck Array at first, but I have forgotten it. ”

When I first studied history, the teacher talked about the mandarin duck formation, but unfortunately it was an extracurricular interest and was not recorded in the exam......

Huang Jun, Zhang Hong also felt sorry when he heard this, it would be good if Li Yan really knew how to fight the Mandarin Duck Formation, you must know that Qi Jiguang's prestige was shocked in China at the beginning, and he was the idol in the minds of these soldiers, after all, who doesn't want to be a Han Xin in the world?

"However, I heard that Qi Shaobao recorded the method of military training in his books "The New Book of Discipline and Effectiveness" and "The Actual Record of Military Training", if you can get these two books, you will be able to train an army that is no less than the Qi family's army," Li Yan thought about it and added.

It's a pity that these two books don't have a ...... now.

"However, although I don't know how the Mandarin Duck Formation is trained, but in fact, the key lies in this 'tactical coordination', the reason why the Mandarin Duck Formation can defeat the enemy is that it is in the tactical coordination, if it can be coordinated in an orderly manner, it is more than enough to deal with the Ming army." Li Yan stared at the two and said.

Huang Jun and Zhang Hong still admired Li Yan's wit, so they hurriedly clasped their fists and said, "Then please watch the army for advice." ”

"Please select ten capable warriors each and hand them over to me for demonstration," Li Yan said.

Huang Jun and Zhang Hong glanced at each other, nodded, and asked his own soldiers to run quickly with the order flag and selected twenty shrewd and capable soldiers to report.

After the twenty people arrived to report the number, Li Yan took Huang Jun and Zhang Hong out of the military tent.

"Send all the blades down," Li Yan commanded to the left and right.

Soon eight "spears", eight "long knives", and two "fire guns" were sent.

The so-called spear is a piece of bamboo, and the long knife is a wooden stick, and the fire gun is also a wooden stick, there is no way, the conditions are like this, there is no actual blade to use for training.

"Please also ask each of the two posts to stand in a column." Li Yan turned his head to Huang Jun and Zhang Hong and ordered.

Hearing this, the two nodded, and immediately raised their voices and gave an order, directly dividing the two teams into two columns and standing solemnly.

"What's the chief, Wu Chang is out of the ranks!" Li Yan ordered loudly below.

Six sturdy men stood solemnly in response, Li Yan's deterrence was undoubtedly effective, and now these soldiers are very afraid of this observer, and they are quite like that for the execution of Li Yan's orders.

"The head of the spear is tied with a red rope, and the chief of the Wu is tied with a black rope" Li Yan waved his hand, and several personal soldiers went down with the rope to tie the rope for these "spears" of the chief of the army.

Huang Jun and Zhang Hong, who were watching, looked confused, not knowing what Li Yan was going to do.

"Wait a minute, when fighting, when the rope color prevails, the commander needs to follow the red rope, and the soldiers need to follow the black rope, understand?" Li Yan said slowly.

During the Anti-Japanese War, the Japanese army would form a battle queue based on the plaster flag on the rifle during white-knuckle warfare, and play a very strong role in white-knuckle combat.

Hearing this, the soldiers all nodded thoughtfully, they might not be able to understand, but now they could only nod.

Li Yan saw that the soldiers nodded, so he also nodded, and continued: "In any battle, it should be a unit of ten people, and if it is an enemy, it should be a unit of five people. ”

When the soldiers heard the military stick, they couldn't help but shrink their necks, although Li Yan canceled the military staff, it was also uncomfortable to be flogged.

"Whenever there is a battle formation, the sword and shield bearers should be in front, holding a big shield to protect them, so that the spears and firearms will not be short-handed by the enemy," Li Yan said slowly in his mind.

"The sword and shield defend, and the spear is used as an attack, open the shield to assassinate, and retreat into the shield with one blow," Li Yan said, pointing at the spearman.

Huang Jun and Zhang Hong nodded while listening, obviously agreeing with this style of play.

"What about the firecrackers?" Zhang Hong suddenly asked.

"The fire gun is good at breaking armor, and its gunpowder smoke can confuse the opponent, if you encounter the opponent's spear or heavy infantry, open the shield and hit it with the gun" Li Yan nodded and said.

"The firebolt is loaded slowly, and when it retreats with one blow, it will be reloaded into the shield, and when the loading is completed, and then slowly advance, the city wall is already cramped, and it is difficult for the enemy to deploy even if he has a large army, so it can be transferred in four or two" Li Yan said slowly.

Huang Jun and Zhang Hong frowned and nodded frequently, Li Yan's set is novel but there are two problems, first, this kind of equipment needs are not available to the reserve army, and it is difficult for the elite of the camp to form such a coordinated attack team, you must know that according to the ratio of two-tenths, it will cost more than two hundred.

There was no such number in the entire camp......

"If you don't have a firebolt, you will replace it with a bow and arrow and a crossbow machine," Li Yan said after thinking for a moment.

This is a good way, although there is a lack of firearms, but there are still a lot of bows and arrows, although the quality is worrying, but it is enough to kill the Ming army at close range.

"It's wonderful to watch the army, but there is a shortcoming," Huang Jun touched his chin and said slowly.

"What?"

"How's the field?"

This formation may be useful in siege, but the ability of field warfare is very questionable, field battles are all large corps operations, and this kind of combat with the army as a unit is obviously not applicable.

Hearing this, Li Yan spread his hands with a smile and said, "Where in the world is there a formation that can be immutable?" Even Qi Shaobao's soldiers do not only rely on the mandarin duck formation, the formation should change from time to time, and now there are few effective soldiers, and it is just right to use this formation for siege first, if it is a field battle, he will use other formations. ”

Hearing this, Huang Jun and Zhang Hongcai nodded reassuringly, they were afraid that Li Yan would use this formation in the field, you know, it is easy to make a big deal if you use such a formation in the field.

"However, this method has extremely high requirements for coordination, and you must practice day and night, and you must not carry it, so as to defeat the enemy." Li Yan arched his hand and said.

Huang Jun and Zhang Hong are both people who have seen big scenes, since they think there is no problem, then Li Yan will start to implement the whole army, and strive to make every army can be used successfully before entering Ruzhou, so that when they arrive in Ruzhou, they will not be caught off guard in the face of the tragic siege battle.

Of course, unless it is absolutely necessary, Li Yan will not be willing to play any ant siege, no matter how exquisite your formation is, such a siege will cause a lot of casualties, the best way is to directly collapse the city wall, so that the siege is the least casualties.

Out of this consideration, Li Yan has already planned to recruit a group of "engineers" who are good at civil engineering operations, if they can use tunnels to attack the city, it must be the best, dig tunnels, and then blow up the foundation of the city, so that the city wall will naturally collapse.

However, this kind of technical work has very high requirements for technical arms and gunpowder production, and it is not realistic at present, so we can only start with talents.

So Li Yan told Wang Jinbao to go to the army to find soldiers who were good at civil engineering operations for recruitment......
