"Master, it has been said in ancient times that there is no general who always wins, so how can there be a theory that the war is undefeated?" Since the last time Master Duan told the next class to teach the theory of being undefeated in battle, Xue Ning had this question. After waiting for three days, and finally waiting for Master Duan's teaching and the ceremony was completed, Xue Ning stood up and asked. Duanfuzi glanced down from the case, saw that all the students had doubts on their faces, and asked, "Xue Ning, a division of thousands of defenders against 10,000 people, the city is broken and the defenders are all killed, who is the winner?"

Xue Ning pondered for a few breaths and replied loudly, "As far as the results of the battle are concerned, the winner is the army of 10,000 people attacking the city. However, the army defending the city was exhausted, although it was defeated, it was still glorious. ”

"The ram praises me. What do you think?" asked Duanfuzi again.

The students thought that what Xue Ning said was very true, and the attacker would win. The ram replied respectfully to me.

"Ou Xiaoxiao, what do you think?" Duanfuzi asked again.

"When the siege is broken, what the students see should be victorious. Ou Xiaoxiao stood up and replied.

"And there was a division of a thousand men against the enemy who came to attack ten thousand, and although he killed three thousand enemies in battle, he was defeated in the end, and the city was broken and the defenders were killed. Who is the winner?" Duanfuzi did not comment on the three of them's answers, and looked at Xue Ning and asked again.

"This, the defenders slashed three times the enemy with a thousand men, and of course should be the victor. Hearing the master's question, Xue Ning was a little embarrassed and replied. The master was still noncommittal when he heard this, and then looked at Ou Xiaoxiao.

"Outnumbered, three times as many enemies are destroyed, and the defenders deserve to win. Shicai said that attack is victory, and he instantly self-destructed his words, and Ou Xiaoxiao's face was a little unbearable. The master did not pay attention to him, but looked at the ram and sang to me.

"Master, the student understands. Victory or defeat in wartime should be counted by battle damage. If you kill more enemies than you lose, you win, and if you don't, you lose. The ram praised me and rejoiced, and when he saw the master's disdain, his face fell again.

Duanfuzi asked a few questions one after another, which made the students gradually feel something. Victory or defeat in a war is by no means an easy matter to decide.

"On the battlefield, the commanders and horses, weapons, food and grass, medicine and clothing can affect the situation of the war, the so-called undefeated, refers to the management of the army, no matter how big or small, compared with wartime, the benefits are useful, the short can be avoided, the long can be raised, and the combat power of their own side is endless. Wouldn't it be a victory to wipe out a thousand new soldiers and an army of 500 tigers and wolves?" Duan Fuzi said in a sonorous voice, "Soldiers, horses, equipment, grain, grassland, and land are all occupied, and what joy is there to win? You can protect yourself when you encounter a strong enemy, you can annihilate a weak enemy, and you can win a battle that matches the enemy, which is to be undefeated!"

After hearing this, the twenty-four people in the audience replied in unison, "The students have been taught!"

Duanfuzi's face was gloomy, and he said, "Dahua's military strength is not superior to the Turkic State and Xian Ma, not to mention that it has already formed an alliance. Once a war breaks out, I hope that you can meet the enemy in the front, and the army will be supplied to avoid worries, and you will serve the court to some extent!"

All the students replied in unison, "Students should do their best to serve their family and country!"

Duanfuzi's face softened slightly, and he said, "Listen to it." ”

When the army is on the march, the continuous and majestic rain can cause the whole army to be submerged and die without a fight; a sudden cold can make the whole army cold and unable to fight; the scorching heat for several days can dehydrate the sergeants and die of thirst; if there is a strong wind, the soldiers, chariots and horses will even be swept away by the wind and there will be no trace of them. The harm of time is fiercer than that of a strong enemy. The time is uncontrollable, and it is necessary to first spy on the time of day before moving to attract troops in wartime, and if the time is unknowable, it is advisable to replace reckless action with immobility. When Master Duan spoke, his face was respectful. "In the first year of Taifeng, Xia Yanru, the fourth son of the emperor, led troops to change the defense for the first time. When the army marched to the bank of the Yu River, seeing that the moonlight was quiet and beautiful, the flowers and birds were reluctant to go any further, and despite the repeated warnings of Qin Tianjian, he forcibly garrisoned the army on the side of the river. That night, a torrential rain fell upstream, and the flood water channel surged, and the soldiers hurriedly got up when they heard the roaring sound, but they still could not escape, and in an instant, more than half of the horses were washed away, and more than 20,000 people were killed and wounded! Xia Yanru was also given death according to his crime. ”

"In the spring of the eleventh year of Yuancheng, a major epidemic occurred in the snow country, and more than half of the livestock and poultry in the country died of disease. In order to provide for the people's livelihood and military needs, the Snow Country cavalry entered the forest county to loot and burn. Shi Zhilin's general Lan Dierui led a cavalry vanguard battalion of 3,000 men to chase the enemy, and after reaching the foot of Yalu Mountain, they were trapped in the tundra, and only 25 of the 3,000 cavalry returned alive. Duanfuzi said lightly, his face was difficult to hide his hatred, "I don't know the terrain, I march rashly, and if I am not careful, the whole army will be wiped out." It is the way of the generals, and the place must be advantageous. The outpost is in front, and the march is behind. The division of 1,000 people is equipped with 10 sentinels, and the division of 10,000 people is equipped with 50 sentinels, two by two, day and night, the sentinels from afar travel 300 miles back to the camp to report to the camp, the big sentry every 100 miles back to the camp to report, and the small sentry go out 50 miles to return to the camp to report. Regardless of internal affairs, the whistle system must not be taken lightly. ”

"The Lord will be at odds, and war may cause great calamity. In the twenty-third year of Pingzhao, King Hulin of Xian Ma Kingdom rebelled, and after the defeat, he led his troops to flee to Duta Prefecture in the west of Chunan County, Dahua, and occupied a garrison to recuperate. Wu Lingbao, the general of Chu Nan, and Duan Feiyan, the general of the garrison, were ordered to lead 50,000 troops to quell the rebellion. Wu Lingbao led 30,000 troops to attack the enemy head-on, and the two sides clashed fiercely. Originally, Duan Feiyansu, who was from the enemy's rear one hour after the confrontation, stepped forward to attack Wu Lingbao, and wanted to take the opportunity to weaken the strength of the southern Chu army, and delayed the attack to come forward to respond, resulting in almost all the southern Chu army being killed, and Wu Lingbao was also killed by the enemy in the chaos. The high-spirited Hulin rebels turned around and attacked the garrison army led by Duan Feiyan again, but the garrison army was afraid of the enemy when they saw the enemy's menacing, and they fled without a fight, and were chased and killed by the Hulin rebels. In this battle, the 50,000 defeated and fleeing Hulin rebels destroyed our Dahua 50,000 elite divisions with less than 8,000 casualties. It's better to be a soldier than a soldier, and you will be defeated by the discord of others!" Duan Fuzi said this, looked deeply at everyone, and said, "On the battlefield, it is not your relatives and old friends who can live your life and save you from danger, but your bloody robe." In wartime, people are at peace with each other, and people are jealous of each other. The generals are mighty, the soldiers are fierce, and the upper and lower hearts are invincible!"

Duanfuzi's three words of general soldiers made all the students deeply understand the interests of tomorrow's time, place and people, and they all felt it for a while. Xia Chenghuan stood up and said, "There are three materials of heaven, earth and man, those who know it are many and those who are good at using it are few, if Chenghuan generals are in the future, they will rely on the time and place when they are marching outside, and they will be with the generals and soldiers in the station, and they dare not forget the teachings of the master!"

Duanfuzi glanced at Xia Chenghuan, ignored him, and continued, "Governing the army for a general is by no means as simple as leading the troops to fight. Nothing is trivial in everyday life. The sergeants need to supply two meters and a few stones a day? How much meat and vegetables are salted and oil? In peacetime, the soldiers should not starve, and in wartime, they should ensure that the soldiers have meat to eat, and this is said that the emperor is not short of hungry soldiers! The soldiers should wear clothes, hates, robes, armor, and armor? The four seasons should not be changed to make the sudden cold and the sudden heat to be heated. And so on! Even whether the toilet chips in the army are sufficient or not, we need to be careful. If the directors are small, the military will be easy to gather!"

"Master, if things are so complicated, how can you manage them as a general of an army? Students often hear that the generals are incompetent and tired to death of the three armies!" Huangfu Tianzong stood up and retorted.

The master looked at him, his eyes were quite approving, and he said, "How can the so-called concern be a matter of being close to everything? If the person who arranges it properly is the director, is it possible to ask the commander of the army to take inventory of the toilet chips? Under the constraint of governing the army, the subordinates are effective, and the chief general is less worried." ”

Huangfu Tianzong held his hand and smiled shyly, "Yes." The student misread Master's words!"
