"Remarkable! It's a great battle! ”

In the lecture hall of Pingyang City, Fei Qian took the information he had just arrived, exclaimed, and then handed the battle report to Xun Chen beside him, "Come, you all have a look." ”

In addition to Zhang Liao, Huang Cheng, Xun Chen and Zao Yi, there were several other people who participated in the lecture hall. Gong Jun and Wei Du belong to the middle and low-level officers, and they belong to the type of experience that is listening to the side.

Xun quality, the word is too primitive, it belongs to the new personnel, and the children of the Xun family who came to the side branch are now following Xun Chen to do books.

There is also a person, called Zhang Yun, the word Yiyang, who also found Pingyang during this period of time, and his learning is quite miscellaneous, and he can also use the art of Qihuang with both hands, and now he is also serving as a secretary in Pingyang.

Comparatively speaking, Fei Qian's intelligence work will be slightly better than that of other princes, after all, it is normal for caravans to come and go now, and it is normal to carry some private goods.

Normally, Cao Cao's territory, well, is quite not very good.

It's like Go, with a golden horn and a silver edge and a grass belly. To the north is Yuan Shao and Gongsun Zhan to fight for the corners, while there are Qingzhou and Xuzhou in the east, Yuan Shu's territory in the south, and the tattered Henan Yin in the west, and Cao Cao's current Yanzhou is on the central belly of this big chessboard.

The real land of the four wars, as a result, was resurrected by Cao Cao in history.

Cao Cao and Yuan Shu, two chess players, met for the first time on this big chessboard. In this battle, Yuan Shu can lose, but Cao Cao can't afford to lose, Yuan Shu loses, it's a big deal to retreat, and Cao Cao has no way to retreat, once defeated, it will be immediately divided and uncontrollable, and the result is that Cao Cao, who is in a disadvantageous position, won.

"Get the map!" Fei Qian said to Huang Xu beside him.

The improvement of the map is a thing that has been gradually improved since Fiji Qianqian came to the state.

The picture is said to have come from Xia Yu at the earliest.

Legend has it that when Xia Yu cast the Huaxia Jiuding, he cast the image used to represent the strange things in various directions, or the pattern of the landscape, or the fish and beasts, which is considered to be the prototype of the Chinese map.

Later, during the Zhou Dynasty, maps were widely developed, not only in military affairs, but also in production and land management. During the Spring and Autumn Period and the Warring States Period, especially because of the frequent wars, maps have become an indispensable tool, and large-scale water conservancy projects and civil engineering projects at that time have promoted the development of the entire map.

Of course, the picture represents a kind of power more often, a kind of control and sovereignty declaration of the land, just like the key in the later generations, although there are fingerprints or other unlocking modes, but still many people like to use the most primitive way to unlock......

The maps of the Han Dynasty have already known how to use unified graphics to represent related things, such as using horizontal mountain lines to represent mountain ranges, and additional halo lines to indicate the range and direction of mountains, and also using fish-scale-like lines to represent steep cliff terrain, not only that, but also used to represent the upstream of rivers with thick lines, and downstream with thin lines to outline the distribution of water.

As for the villages, counties, and other places where people live, they are all written in the circle with a circle and a name, if there is a box, it means that there is a garrison, and if it is a separate box or triangle, it means a fortress or fortress of the field garrison.

Solid lines are used for open official roads, while dotted lines are used for trails and mountain trails.

It can be said that the only problem with the maps of the Han Dynasty is that there is no fixed scale......

As for the accuracy of the map, it can only be said that it is limited to the lack of manual depiction and surveying methods in the Han Dynasty, so it cannot be said to be a major defect.

Of course, this is a very professional map, usually only in the central court, and even this art of drawing maps is passed down from generation to generation, secret, as for the map of ordinary townships and counties or low-level villages, that is to see the wisdom of the people, freehand and shape both.

Fei Qian benefited from Cai Yong's collection of books, and before the fire burned Luoyang, he also obtained some Yuntai literature and atlases from Li Ru, so he generally built a relatively accurate map library. Among these maps, there are not only maps of the Central Plains of China, but even some maps of the Western Regions or Mobei, but the true validity of the maps on the edge of these territories or even beyond remains to be verified.

The map of Chenliu's vicinity was quickly taken out and spread out on the large rectangular table.

People who look at the map for the first time will always feel dazzled, all kinds of shapes and colors shake under the eyelids, and they don't know which side to look at, but they are used to it, and they will naturally understand, for example, most of the villages and counties are actually along the water source branch, so if you want to find the county seat or something, you should first find the water system.

Fei Qian quickly found Fengqiu and Kuangting.

In fact, these two locations are on the east and west sides of Wuchaoze......

Fighting a war is inseparable from the supply of water, and the birds and beasts growing in the swamp are also a good source of supply for the army, so it is not surprising that Wuchaoze has become the preferred location for many soldiers.

At this time, everyone in the martial arts hall also passed on the battle report about the battle between Cao Cao and Yuan Shu. The battle report was not long, only forty or fifty words, but it was thrilling.

"Yuan entered Chenliu, tun sealed the hill, and made the general garrison in Kuangting. Cao feints, Yuan rescues, fights, Yuan is broken, and is defeated back to Fengqiu. Cao Weizhi, Yuan fled to Xiangyi again, regained defeat, and went to Jiujiang. ”

"The first question," Fei Qian said when he saw that everyone had finished reading the battle report, "Is there any problem with the general arranging his troops like this?" Be careful, analyze from the perspective of the pre-war point of view, and don't let the results dictate your thoughts. Think about it, if all of you here at this time are the rear generals who command the army, how do you put this posture? ”

Talking about martial arts, talking about martial arts, since you want to talk about it, of course, you can't push forward from the result, if it is purely result-oriented, it's not impossible, but it also loses the meaning of talking about martial arts, everything is good to wait for the result, what else to talk about?

So is there really a problem with the layout of Yuan Shu?

The army of Yuan Shu's headquarters was stationed in Fengqiu, and then the branch sent Liu Shen to garrison Kuangting, surrounding Wuchaoze, forming a horn trend, attacking the left to save the right, attacking the right to save the left, the strength is superior, the grain and grass are superior, whether it is a head-on battle, or delaying consumption, Yuan Shu can support it, there is no problem.

Zao only stared at the map, looked at the Fengqiu and Kuangting on the left and right sides of Wuchaoze, and then gestured and said, "If my forces are superior, I will probably choose these two places as well...... Not to mention anything else, Fengqiu can cross the water, Kuangting can be based on the water, both of which belong to the key places......"

Jishui and Pushui are the two water systems that connect Wuchaoze, Jishui is larger, and Pushui is smaller, Fengqiu and Kuangting are just the ferries of these two water systems closest to Wuchaoze.

In terms of tactical layout, there is no big mistake in Yuan Shu's layout.

"Maybe this was originally General Hou's plan to lure the enemy...... Xun Chen stroked his beard and said in a deep voice, "Fengqiu is already a place to go deep into Chenliu, if you continue to move forward, on one side is the Xiahou army stationed in Baima, on the other side is the Cao army, and on the other side there is the county soldier Yu Suzao ......"

Lure the enemy?

There is also this possibility.

Zhang Liao nodded and said: "From a defensive point of view, the troops are stationed in Fengqiu, one is to defend the white horse soldiers, the other is to resist Chen Liu's army, and Kuangting is supplemented to prevent the Cao army from attacking on the side and cutting off the grain road...... In terms of attack, the frontal sealing mound can resist the combined forces of Cao Jun and Chen Liu, and it can also use Kuangting's army to attack the flank of Cao Jun...... Overall, there really is nothing wrong with it. ”

"But......" Huang Cheng scratched his head and said with some doubts, "...... But if there was nothing wrong with it, why did it fail? ”

Fei Qian nodded in agreement with Huang Cheng's words, and then looked at Xun Chen, although he had some answers in his heart, he still wanted to hear what these people under him thought.

Many people think that defeat is defeat, and there is so much to say, but it is precisely because Yuan Shu did not make major mistakes at the beginning of the entire campaign that Cao Cao's victory was particularly exciting.

Xun Chen saw Fei Qian's eyes, nodded slightly, and also knew that Fei Qian was showing himself an opportunity, so he stepped forward, dotted on the map with his hand, and said: "Yuan Jun is based on this layout, most likely planning that the Cao army will inevitably meet with the sour jujube Chen Liujun first, and then attack Fengqiu to seek a decisive battle, while Kuangting's garrison can take this opportunity to attack Cao Cao's back road, on the one hand, it can cut off the grain and grass of Cao's army, and on the other hand, it can also be attacked from both sides, and eliminate Chen Liu and Cao Jun in one fell swoop; If it is the second case, the Cao army does not join forces with Chen Liujun, but wants to attack the Kuangting of the Yuan army first, then the Yuan army can bypass Wuchaoze and give the Cao army a blow in the back......"

“…… However, there must be someone among the Cao army who had insight into Yuan Jun's plan," Xun Chen paused, not knowing if he remembered something or someone, and then continued, "...... The horned army of Kuangting, which sent a small number of soldiers and horses to feint against Yuan Shu, waited for the Yuan army to come to help, and attacked the Chinese army, and after the Yuan army was ambushed, it failed to effectively collect the soldiers after the panic, and finally suffered a great defeat......"

Zao Yi nodded and said: "The most important thing for the Yuan army is not to lose on the layout, but to defeat the enemy......

Zhang Liao and Huang Cheng looked solemn.

And Xun Zhen and the others, who were listening with their ears pricked up on the side, were staring at each other, and they couldn't wait to write down the words they said in a small notebook......

Fei Qian pointed to Kuang Ting on the map and said, "This is a siege point to send reinforcements......

Cao Cao's combat strategy was to attack Yuan Shu's weak link with the main force first, and then attack the main force led by Yuan Shu, so as to avoid the passive situation of fighting on both sides; If Yuan Shu led the main force to help, he could only surround Liu Shen and attack Yuan Shu on the march with the main force. Sure enough, when Cao Cao attacked Kuangting, Yuan Shu did not think deeply, that is, he rashly led the main force to come to the rescue, and completely fell into Cao Cao's plan.

Cao Cao seemed to be attacking Kuangting on the surface, but in fact he was luring Yuan Shu's main force out of the fortifications, and the large army detoured to ambush the flanks of Yuan Shu's reinforcements, waiting for Yuan Shu's front army to cross the border, and suddenly launched an attack on Yuan Shu's Chinese army, and Yuan Shu's command center was suddenly attacked, causing Yuan Shu's command system to be paralyzed, unable to organize effective resistance, and then the whole army was defeated.

After the battle of Kuangting, Yuan Shu led the remnants to retreat to Fengqiu, and then Cao Cao took advantage of the victory to pursue and surround Fengqiu, and Yuan Shu broke through and fled to Xiangyi. Cao Cao continued to pursue, and flooded Xiangyi City above Taishoupi, but Yuan Shu could not defend it, so he fled to Ningling and entered the territory of Yuzhou. In the end, Yuan Shu fled to Jiujiang in Yangzhou, where he escaped from the pursuit, and Cao Cao also retreated to Yanzhou.

“…… Encirclement to send reinforcements, encirclement ...... Send reinforcements ......" Xun Chen stroked his beard and nodded, "That's true, the four characters of the prince and the prince are the true meaning of this battle......"

Who would have known that as early as this period, Cao Cao played such a beautiful textbook template for encircling points and sending reinforcements? The point is that this tactical method is not within the 36 strategies......

Fei Qian suddenly thought, well, this thirty-six plan, it doesn't seem to be a book yet, do you want to do a crash course or something? Not to train top generals, but to train middle-level soldiers, such as Qu Chang, military marquis, etc., as long as they are familiar with the thirty-six strategies, is there a chance to exempt some of the enemy's strategies to a certain extent?

Well, it seems a bit of a headset.

“…… Prince, Prince? Zao Yi saw that Fei Qian was suddenly a little distracted, and for some reason, he called in a low voice.

Fei Qian came back to his senses, smiled, and said, "Think of something else...... Encirclement and reinforcement, the enemy surrounding a town uses it as bait to attract reinforcements from other places, and its real purpose is to fight the reinforcing enemy and achieve the goal of annihilating the enemy, but to achieve this goal, there must be two prerequisites, one is concealment, and the other is mobility. ”

"Concealment is to conceal their real target, and the second is to conceal the reinforcements, the maneuver is very simple, basically, if you can't enter the ambush site first, there will be some difficulties in attacking the reinforcements......"

"Sun Tzu has a cloud, and if he does not fully understand the harm of using soldiers, he cannot fully understand the benefits of using soldiers. Therefore, mobilizing the enemy is not necessarily a benefit. In the battle between the two sides, it is normal for us to mobilize the enemy in every action. A wise general will make the enemy act according to his own arrangement through his own mobilization, but he will mobilize the enemy army but expose his weaknesses......"

"There are still many variables in encircling and sending reinforcements, and it is okay to encircle one dozen or fight more than one, and at the same time, if the enemy army uses this plan on us, how will we deal with it? This is the homework in today's lecture hall......" Fei Qian looked at everyone, and suddenly changed the topic, "Well, the strategy left for you will be handed over within three days......"

Fei Qian ignored Huang Cheng's depressed expression on the side, and continued: "...... Those who are excellent in strategy and argument will go out to the army with a certain person, is it bad...... Hehe......"

When everyone heard the word "out of the army", they couldn't help but feel refreshed, and then exchanged glances with each other.

Then Fei Qian pointed to Xun Qian, Zhang Yun, Gong Jun and Wei Du, who were listening on the side, and said, "...... Although you don't have the right to lead the troops alone, you can also write about it, and if it is well written, you can consider it and give you the opportunity to lead the troops independently......"

When everyone heard this, some were happy and some were sad, but they all hugged their fists and promised.

Well, it's really good to be a boss and assign tasks casually......

"By the way," Fei Qian said with a smile, "...... No plagiarism, each write their own, if there is any similarity, hehe......"

"Yui!" This time, everyone's expressions were much more serious.

Talk about martial arts, talk about martial arts, and talk about it in the open hall. On the surface, it was set up in order to let more people understand the military and not be helpless when they encounter problems. At this stage, no one will object to the establishment of this lecture hall, but these people do not know that in addition to the superficial role of Fei Qian's lecture hall, there is actually a deeper meaning......
