"Defending the City" is mainly a sample demonstration of military classics in response to infantry sieges. But most of it, in fact, doesn't have much reference value. In particular, Zhang Jiashi knew that most of the troops attacking De'an were not comparable in attack power compared to the defensive capabilities of the Song army.

However, there is no doubt that compared with the situation of Fu Zuoyi's defense of Zhuozhou in later generations, there are not many successful examples of defending the city of the same level or weaker than the strength of the attacking party. Therefore, in many aspects, although "Defending the City" does not have a certain reference value for the battle between Qin and Hungary, it is just that in the design of some more feasible equipment, Zhang Shixin chose to use it partially.

Among them, the equipment for long-range strikes is the focus.

......

Among the relevant military works, there is one work that is very interesting, that is, its content is basically compiled by the author. (It is possible that some of its contents are forgeries in the name of later generations.) ）

This book is "Mr. Cuiwei's Northern Expedition".

"Mr. Cuiwei" is the author Hua Yue, who has no relevant records of joining the army, but his "Pingrong Ten Strategies" was a relatively famous Shangshu in the Song Ningzong period, and perhaps because of his related policies offended the authorities, he was finally unable to implement his ambitions, and became only included in the "Zhongyi Lu" in the "History of the Song Dynasty", rather than a separate biography:

Hua Yue, whose name is West, is a martial arts student, a good man with light money. Han Yan was in charge of the country, and Yue Shangshu said: Since the beginning of October, the people of the capital have been wandering around, if they will lose their families, and the wives of the armies will cry and grieve, if they will drive away the water and fire. Ignorant of his nationality, he wants to be silenced, and he is shocked by rumors, and he doesn't know what he knows. The ministers Xu Kaozhi, the guards sneaked day and night, the cardinal's handing of sparks, the battle of Rong was twice as usual, and the journey of the post was both in the past, knowing that His Majesty would have something to do in the north.

The relatives of the descendants of the clan are in the best position, holding the authority of the whole family, taking bribes from the public; raising stateless servants, entrusting them with their hearts, selling famous weapons, rewarding them privately, looking down on artifacts, and peeping at the sect and society, they are becoming increasingly hot and do not dare to pay attention to you. In addition, those who suffer from it are also in my heart.

The courtiers have the resources of mediocrity, invite the marrying master, and suddenly enter the government, and those who have the resources of the courtiers, attach the nobles, and make the nobles. Chen Ziqiang is shameless, greedy and unstoppable, privately planting the party and the family, and everything he sees and does, but he knows his father. In addition, those who suffer from the humerus are also.

Shuang, Yi, and Ruyi Zhu Li's greed and cowardice are unscrupulous, Ni, Xu, Zhuo, and Gao are useless, Zhu Wu's favor is monopolistic, and Zhu Peng's Yong is unscrupulous; Huangfu Bin, Wei Youliang, Mao Zhitong, and Qin Shifu's carving of the army's heart and sore morale, so that Chen Xiaoqing, Xia Xingzu, Shang Rong, and Tian Junmai's disciples are all useless, and they have to carve their own ****, and carve blood from their anointed ointments on weekdays, so that they can not get it. In case His Majesty pays a big deal, his leader will not be able to protect himself, and Xi Xuan will plan for His Majesty? Cheng Songzhi took a concubine to seek knowledge, or entered the palace by selling his sister, or entered the cabinet with a wife, Lu Zhigongzi was the lang, and the rich palace was filled. In addition, those who suffer from my ears and eyes are also.

Su Shidan was a filthy official and a nobleman, and Zhou Yun was a subordinate and a general. In addition, those who suffer from choking my throat also. His so-called external patients are really not worried, and the external patients have been covered by Zhou Wu. "Lile conquest, from the Son of Heaven". Those who are precious to China are all under the orders of His Majesty. Now it is also with the power to take the life and dethrone the throne, and it is not from Your Majesty, but from your Majesty. Yes, I have two China also. The fate is not from Su Shidan and Zhou Yun. Yes, I have three Chinas, too. The Jurchens were still able to force our Huai and Han to be in a small place, and they used to be called the dwelling of foreign troubles, my heart, my heart, my ears, my eyes, my minions, and my throat, but not Feng Lingwu's Zongmiao Society? This also enlightens China's hundreds of millions of enemies. Now don't you want to go to my heart, my humerus, my minions, my ears and eyes, my throat, and my husband's hundreds of millions of enemies, but I want to empty the country's army, exhaust the country's wealth, and follow the distant people in the land of blood, and don't care about using their hearts?

The minister tasted the deduction of the military book, since the last year Shangyuan Jiazi, Wufu Taiyi first Wu Fen, the four gods of the direct Fu to Linjing, Chu, the beginning of the attack next to the Linou, Yue, Qingmen direct envoy handed over to the You, Ji, black kill the zodiac is pressed by Yan, Zhao. The test method is the longest, and the guest is the shortest. The soldiers are the first to be the guests, and the last to be the main ones. Between the six years from Tai Sui Yi Chou to Geng Wu, it is not conducive to the first move. Fu Qibian Alliance violated righteousness, scratched my territory, as for the matter is not obtained, and then responded, then the anti-master is the guest, still said a few. In case the first thing of the country is proposed, the generals will be inside and outside, the soldiers will be outside, the liver and brain will be thousands of people, and the blood will be thousands of miles. This number of days is not conducive to the first move. The generals are handsome and foolish, the army and the people are resentful, the horse politics is not spoken, the knights are not familiar, the heroes are not out, the heroes are not collected, the food is not abundant, the shape is not solid, the mountains are not repaired, the fortress is not set up, although I bring a million armor, the food is thousands of miles, and the division is useless, and the self-defeat without a fight. This personnel is not conducive to the first move.

I hope that Your Majesty will be in trouble except for me. Otherwise, the chaotic ministers and thieves will destroy the crown and crack the crown, oh the poems of Jiuxi Longen, the appearance of the noble, the concubines and concubines, the ministers and generals, the fish and meat soldiers, the miserable creatures, the distant map of the hundred generations, and the legacy of the ten temples. Although His Majesty wants not to die with him at this time, he will be forced by disaster, and the power comes from people, and he will bow his head to the end, and he can eat the umbilicus.

Before it happens, it is difficult to win the trust, and the minister is willing to be the court lieutenant of his body, treat his military division, and return the work to play Kai, then the head of the minister will be handed to the Quartet, thinking that the world is the ring of the king who deceives the king. Fu or fight to find each other, defeat one after another, strong enemy attack, traitorous ministers inside, and the ministers are in line with what the ministers say, and then let the ministers return to the old fields, forever for the people who are despised.

The book played, and he was furious, went down to Dali, and degraded the land of Ningyuan. The county guard Fu Bocheng took pity on him and ordered the jailer to make it impossible to enter and exit. Bo Cheng went, guarded Li Dayi again, and was reinstated in prison.

He was punished, released, re-enrolled in school, and was a subordinate of the former secretary of the palace, and he was depressed. Seek to go to Prime Minister Shi Miyuan, and the matter is jue, and he will be in prison. Prison equipment, sitting on the minister should be killed. Ning Zong knew Yue's name, and wanted to be born, Mi Yuan said: "It is the one who wants to kill the minister." "He died with a rod in the East City.

......

Hua Yue's "Mr. Cuiwei's Northern Expedition" has its famous "Ten Strategies for Pingrong":

On the Emperor's Book Again:

On the auspicious day of the third year of the opening of the Jubilee, when the sin of the country was released, the cloth was released and the minister Huayue was dismissed, and the book was dedicated to His Majesty the Emperor.

The ministers bowed with arrogance, begged to dismiss the army, and offended the power of heaven. Regain the mercy of the saints, do not give punishment, and build peace for two years. Since the sin, he has heard the voice of the border and has been in pain, which is the reason why the minister expected His Majesty's affairs today to be judged the day before yesterday. It is better for a husband to save a fire in the scorching heat, than to save people in the turbulence, and to save people in the turbulent water. Now that the fire is burning, the water is drowning, and the resumption will sit idly by and ignore it, then the monstrous disaster of the prairie will not know where it will stop. When he is not burned or drowned, the minister cannot redeem His Majesty's hearing, and the minister's sin cannot escape;

The ministers have heard that the great cause of the emperor is in the heroes, and the demons who sweep the world are the heroes. Emperor Gao can only accept three masters, so the business of the son of the Red Emperor is not made by hard work; Guangwu only recruits heroes, so the merit of Zhongxing is set at the speed of ten or three years. Heroes do not accept and consult with the Confucianism of mediocre subjects, heroes do not recruit but obey the orders of those who try to be hasty, and the ministers know that their prejudices and shallow knowledge are enough to fund the enemy's deep and long-term strategies, and there are few people who do not run to the army and mislead the country. However, Your Majesty's affairs today will be dealt with by scholars and scholars, or by heroes and heroes? The so-called heroes and heroes will rise up in the mountains and forests and worship their fathers; the rivers and lakes are elegant and regarded as the standard; the well-dressed gentlemen have never tasted their door; and the princes have never tasted their names.

Those who study the heart are door screens, listening to the ears, planting ice, hoarding pits, flying ash, walking thunder, wind fences, water gates, wooden cabinets, shaking waves, penetrating stones, and the system of drawing from afar. The people who plan it, Wufu, Dayou, Junji, Chenji, Tianyi, Diyi, Four Gods, Zhifu, Xiaoyou, Minji, Qingmen, and Zhizhi. The person who sings and recites it is Changqing personnel, the secret biography of the princes, the Zhang family Tukou, the nine-star camp, and the book of the secrets of the families. The travelers it made friends with were Tangcheng, Tongbai, Chaya, Haigu, Dongzou, Nanyan, Jiashan, Lu'an, Jiming, Mahis, Yangxian, Fangling, and Xianghuai. The people who look forward to it can reach the distance of Jinjin with the shallow and deep Chaohuai Liansi, and the fat and barren Jingxiang of the Huaihan Dynasty can garrison the number of troops. Those who know it well, Huaidong has many rivers and rivers, and it is not conducive to riding, and Huaixi is full of mountains and forests, and it is not conducive to riding boats.

The people it collects are all Liang Han strange materials, Jing Chu strong men, smoke and cloud pavilions, wave towers, cave medicine stones, and people who occupy the wind and clouds. The people it measured were Shankou, Zongyang, Dongguan, Qijiang, Yugu, Magu, Jiuqu, Gougu, Sheyang, Yangkou, Zhoutou, Yanglin, and the 36 battle sites of Jingxiang, where was the danger, and the 94 cottages in Huainan were the most important. As far as this is concerned, the heroes and heroes regard their husbands, scholars, bachelors and the like, and they are not very different!

His Majesty the Emperor Yangwei, who worked hard to be born between 500 years of age, and restored the industry of Zhongxing for hundreds of millions of years, will be one family in the world and unified in Yixia. All the things of the soldiers, all of them are bent to the end, and it is advisable to move the court in one fell swoop, and the three arrows and the mountains are fixed. He Dabing's two-week starry service, and the great victory did not play evil? He dispatched the handsomeness all over the border, and abandoned it? Digging a pond for three feet, it can defend a city, and the soldiers are also moats. He Changhuai thousands of miles is not enough to limit the defense of the country? He Yuntun is one million, not enough to stuff the criminals of Huai? The size of the land must be fought for, what thief has not handed over, first abandon his city? The grain of millet must be calculated, what thief has not arrived, first self-immolation of his grain and grass? The people of the city can be driven, the rabble can be fought, and the soldiers are also wonderful. Why is the pawn of the new recruits in Zhejiang, Fujian, Jianghuai, and Jinghu today, and the people who are relieved of their problems are the ones who are sick of the unrefined evil of teaching and reading? Why is the rice of Wuchang, Qiyang, Shankou, Zongyang, Chikou, Wuhu, Quarrying, Jiankang and Zhenjiang today, and its piles are accumulated along the river, and they are still worried about their accumulation?

The ministers are thoughtful and skillful, and those who are not favored by His Majesty are all subject to the materials of the army, while the talents of heroes and heroes are not favored; those who are promoted are all people who are in accordance with the rules and standards, and those who are unruly in the general drive are not promoted, so it is like this! From now on, the teacher has traveled thousands of miles, and he has been ordered for two years, and there is not a word of the county and country under the edict of seeking talents, and there is no piece of paper for those who recommend the book of virtues into the chapter. Jing Xiang's widow has not heard of his name; Jianghuai's boldness has not known his face, how can he come out of his own right, and how can his career be able to help? Therefore, he also fought on the first day and the second day, and I don't know what his husband's skills were. The way of life is also out of the army, and the way of death is also out of the army, I don't know why the husband is green and black. Zhang said that he could do it, and Li said that he could stop it, I don't know what Zhang Li Zhi said, which is really yes. The left is said to be attacked, and the right is said to be able to be guarded, I don't know what the left and right say, who is appropriate. If there are ministers who know the soldiers in the temple, then the people who are always dispatched are all real materials; if there are people who know the soldiers in the Xuansi, there will be no luck in those who are controlled. Therefore, if the temple knows the soldiers, those who know the soldiers will advance, but those who do not know the soldiers will retreat; if the Xuansi knows the soldiers, those who know the soldiers will be generals, but those who do not know the soldiers. The soldiers do not know themselves, and all the tricks of dethronement, listen to everyone, I see the success of their cause, and there are those who do not wait for the wise and then know that they will be defeated. Today's business is sitting here. One is to take the soldier but not to be in fact, the second is to recruit the army but not to make full use of it, the third is that the royal rider does not have his own equipment, the fourth is to trap the rider without his strategy, the fifth is to get his place and lose his heart, the sixth is to keep his place and recover without preparation, the seventh is the unclear grace and power, the eighth is not secret, the ninth is urgent and the financial plan is not rich, and the tenth is in the horse government and the horse government is not prepared. The disadvantages of the ten, unless there are heroes and heroes who wash it for His Majesty, he will be defeated day by day, and there will be unspeakable ones. Please present it for Your Majesty.

Pick-up:

The minister read the book "Sun Tzu", and at the end of the thirteen articles, he said in wisdom: "Yin Zhixing is also, Yi Zhi is in Xia, Zhou Zhixing is also, Lu Ya is in Yin." "The king of Yin Zhou, the place where the destiny of heaven is fixed is also important, and the ability of He Yizhi and Lu Yazhi is also for the rise and fall! The method of covering the use of the room is not to worry about the failure of the heroes, but to worry about the heroes going to the country; not to regard the failure of the heroes to be attached as the urgency of the soldiers, but to take the hero's departure as the worry of the heart. Therefore, although Xia is not dead, and Zhi is gone, he is dead, although Zhou is not prosperous, and hope is prosperous. It is to know that the heroes and heroes are going to stay, and they are the weal and woe of the society and the state. And today's urgency is here, not there.

The situation is famous for the mountains and rivers, and the show is made by the clock; the b_ follows the mountains and mountains, and the gods descend. On the day of a thousand years old, the people of the world are born. There must be a leading material, a special son, a dream is not formed, divination has not been seen, living in the poor and lowly Yan customs, hidden in the farmer and merchant Jia Caolai medical divination. Luo Zhi is not good at the Confucianism of chapters and sentences; he is not good at the Confucianism of the rules and sentences; he is not good at the evil of the Lu Lu because of the temptation of the evil of the people; he is not born in the place where the camp is ranked. The cultivators of Sancheng and Tongbai, the woodcutters of Luoyuan and Jiamu, the Gaoyin of Lu'an and Liaofeng, and the traders of Yangxian and Fangling, have many ambitions and are higher than the world. I don't want to use it in the world, so as to make the most of it. However, the upper part will incur no way, and the lower level will have no step to enter, the inside will be searchable and there will be no way, and the outside will have no door to enter. It is necessary that the temple is wider than the Yanna, but it is not estranged; the shogunate is diligent in listening and reading, but not confined to the early twilight; and the superintendent of the prefecture and county is dedicated to recommending and not leaving it behind. There are eight gates: First, there are officials, which means that they are indulged in subordinates, and they cannot work hard; second, they are said to have no officials, and they are said to be in the grass and thatch, and they cannot reach themselves; third, they are called families, they are called generals, and they are handsome, and they cannot be self-effective; fourth, they are heroes, they are called leaders of the rivers and lakes, and they are standard in the mountains and forests; fifth, they are said to be guilty, and they have committed three feet, and they want to get rid of their crimes; sixth, they are not suitable for those who have been in good spirits, and they have violated the criminal law; seventh, they are said to be generals, and they are known to be strategic, and they have been drowned in the army for a long time; and eighth, they are said to be hidden in the official register, and they are not allowed to be distributed.

The ministers and fools want the court to give a clear warning, and the two or three ministers at the top hold their hair and spit and feed, and form the hearts of heroes from all directions; In Zhulu, it is responsible for supervising the prefecture and county, and in the army, it is responsible for controlling the generals, opening the door of pushing and pulling, going to the prohibition of wandering, giving them a literary list, and exciteing them with loyalty. Those who know the interests of the military state are allowed to show themselves; those who know the heroes of the mountains and forests are allowed to listen to their self-recommendations; those who love the king and worry about the country in the world can be exposed; and those who have outstanding talents can be guided. If there is a case of military affairs, the Propaganda Department will be released, the facts will be reviewed, and before the army is paid, they will be hired with the materials. It has rhetoric and rhetoric, and those who are secular will be burned, and those who have exchanged towns and villages will be destroyed. The words are simple and straightforward, and there is no order to abandon them, and they are afraid of being superior to others' qualifications, and they are clumsy in Zhu Mo; In this way, those who hear it will come, and those who do not seek it will be able to know their names, and those who will benefit can be recruited, and those who have no intention of benefiting will also be able to know their caves. Otherwise, the male of the grass and the grass will not be able to be exhausted, but there will be the selfishness of the selfishness of the husband who is snourishing him, and the treachery of the mountains and forests will not be able to be fully collected, and it is appropriate to provoke the wall at the time of enlightenment. Today, our country, with millions of teachers, transporting thousands of miles of grain, the world is sensational, the world responds, and the rate is unheard of to be able to recommend a hero, raise a strategist. I don't know that Huai is 1,600 miles east of Tongbai, and there is one in 110 in the shallow sand, and the sea is all through Jinyan. Along the Huaitun Shouzhi Division, there are only more than 10 from Yukou to Fuguang, and the middle of the stakes is gone, ten or nine. Han from the west of Yingjing for 1,400, the danger of the beach moraine is one in eighty, and the land of Tongzao is thousands of miles flat, inch of land and water, slightly infinitely separated, and Jingxiang guards the soldiers, confident Yang, Anfu to Jingmen, Guanghua is only six or seven tunshu, there are many roads, refusing to resist the four sets of the infant four sets of the front, and the place where the plug is dissatisfied, there is not a person who can be responsible.

Cover the people who embrace the arts, the people who cultivate the clouds and fish the moon, the world is silent, the Quartet has nothing to do, and they are still eager to make a name for themselves, and they are more exhorted to make progress. In the autumn of the cause, who is willing to be alienated from the outside, and if the other is not exhausted, then those who give up Yu Qin will not know that they are not Baili Xi, and those who turn their backs on Chu and return to Han will not know that they are not Han Huaiyin? Yang Zhu Zhiqi can be in the south or in the north; and the water of Meng Ke will be decided to the east and west. Before and after the Jin Dynasty, there is no road to pass; left Zhao and right Yan, nothing can be separated. Is it possible to worry about evil? This is the theory of taking scholars, so the ministers are at the head of the matter.
