The Struggle of the Reborn Prince

To be fair, although Zhao Huan was a very mediocre, weak and even incompetent emperor, his changes in personnel, strictly speaking, was frivolous, but the frivolousness of Taoist king was changed by personal likes and dislikes, and he was no opinion on the ears of noodle and nostalgia, and he had no opinion and believed in the little one.

People say that, but he is not licentious or cruel. He is very good to the ministers, the people, and is very diligent, so he is very loved by the scholars and the people.

At this time, although the situation of Song Ting was very difficult, it would not be impossible to escape the tragic fate of the country's destruction? In fact, it is not necessarily true. Just imagine, even if it is a newly built city in Taiyuan and thousands of tired soldiers in the city,

It was able to hold the Jin army for nine months, and the city defense of Bianjing was the first in the country:

The frequent national wars between the Song and Liao and Xixia and the intensification of class contradictions in the Song Dynasty were the direct causes of the Song Dynasty’s defense system. The city of Tokyo is located in the Central Plains, and there are no mountains and rivers to defend, in order to avoid the "Shi Jin has no preparation" Khitan.

The historical tragedy of being directly trapped in the capital was repeated, so he vigorously built a city and sent imperial guards to form a complete defense system with "a strong city in front and a heavy army in the back". The construction of the Tokyo city defense system can be described as a matter of deliberation.

After Emperor Taizong destroyed the Northern Han in the fourth year of Taiping Xingguo, he attacked Liao in order to regain the sixteen prefectures of Yanyun. However, he was defeated in the Battle of Gaolianghe. In the third year of Yongxi, the Song army was in the battle of Qiguan and Shuozhou.

Zhong suffered another defeat. From then on, Emperor Taizong of Song and his ministers gradually changed from attack to defense against Liao, and there was a negative situation of "resisting them when they come, and not rushing them when they go".

Since there is no hope of regaining the former land of Youyun, it will lose the most important Great Wall defense line of the Song Dynasty to defend against the Liao Dynasty. The gateway of North China is completely open to the Khitan Iron Cavalry, and there is an "unknown mountains and rivers south of Yanji, thousands of miles south of Pyongyang, and the unfamous mountains and rivers of the Fan and Han dynasties and the common people and Han dynasties.

"The situation is not only good for the Liao cavalry in military terms, but also put the Song army, mainly infantry, at a disadvantage. These unfavorable factors have caused the capital Kaifeng to objectively fall into a situation of "dispersed situation and difficulties in preventing maintenance." Therefore,

, it is imperative to strengthen the defense function of the capital itself.

Yuan Hao proclaimed himself emperor and established Western Xia. The relationship between Song and Western Xia also directly affected the defense of Song Dongjing City. After Yuan Hao established Western Xia, he launched three major offensives against Song and Song were defeated. Then, Yuan Hao led his army to Wei.

The state, "a territory of six or seven hundred miles, burned the houses and slaughtered the residents and left" posed a great threat to the western border of the Song Dynasty and directly stimulated the defense construction of Tokyo. Renzong issued an order to restore the two cities inside and outside at the same time.

.

In order to cope with the war against the Western Xia, Emperors further transferred the garrison in the capital to the west, and the civil defense power of the capital was weakened. Therefore, the Song Ting increased the construction of Tokyo city defense facilities to make up for the shortcomings of the civil defense power...

In order to build a safe capital, the emperors of the Song Dynasty did not spare any effort and abandoned a large amount of manpower and material resources to build the Tokyo city and improve the city defense facilities to serve as artificial barriers. The three levels of the outer city, inner city and imperial city of Tokyo were built.

The city surrounded by inner and outer cities has strengthened Tokyo and closely protected it to form a super fortress.

The outer city of Tokyo was built in the Later Zhou Dynasty of the Five Dynasties. At that time, Zhou Shizong built the capital and took the soil of Hulao Pass. It was as solid as iron and even if it was hit by a stone, it was just a pit. The outer city was repeatedly repaired in the past dynasties.

The city moat has been dredged many times. At this time, willows were planted on both sides of the strait by a moat more than ten feet wide. It was forbidden to log them to block the enemy troops siege the city.

Tokyo Richeng is the second barrier to defend the capital. It is military as a buffer zone between the outer city and the imperial city to further ensure the safety of the imperial palace. Zhao Ji issued an edict in December of the sixth year of Xuanhe.

Xiuli City walls, city moats and city gates strengthen defense functions.

The imperial city is located in the north of the central part of Tokyo, and is the location of the Song Dynasty and some central government officials. This was originally the office of the governor of the Xuanwu Army of Tang Dynasty. In the first month of the fifth year of Dazhong Xiangfu in Emperor Zhenzong, an edict was issued to "build the imperial city with bricks."

"This is the beginning of the bricks covered by the ancient Chinese city wall. In addition, the corner towers that were dozens of feet high were built at the four corners of the imperial city, and the bricks covered by the city and the corner towers built on the city were greatly strengthened, and the defense capabilities of the imperial city were inherited by the past dynasties.

Because the city gate is a weak link in defense, it became a deliberate place for the Song court to operate. In the outer city, there are twelve city gates, except for the four main gates such as Nanxun Gate, which are directly under the level of the direct gate because of the Yuluan Road. The rest are all built.

The third floor of the urn city is bent and opened. In addition to strengthening the city gate and building the urn city, it also seals the enemy's horse face during the Yuanfeng period of Emperor Shenzong. This is an appendix to the city wall. Its function is to strengthen defense and cause attackers to be attacked on three sides.

, and it is conducive to reinforcement of walls.

In addition, there are also weapons to defend against enemies on the outer city of Song, a city warehouse is set up every 200 steps, and a defensive weapon is stored. There are war sheds on the city walls. All gates of the outer city are wrapped in pure iron again.

The first step is. In addition, the Guanggu Army was specially established in the imperial guards, which is a professional engineering corps team, and their job is to build and maintain the city defense measures.

The first time the Jin army was at the Kaifeng city, they chose the weak points in the city defense of the Sourzao Gate, Fengqiu Gate and the Bian River upper and lower water gates as breakthrough points, but they were not captured. In other places, because the outer city was wide,

The Jin soldiers could not get close to the city. The method of transporting soil from the cave, and wood stuffed the city moat. After filling some of the city moats, they launched a strong attack, but they all returned in vain, which shows the defense of the outside city.

Solidness.

After the Jurchens withdrew from the siege last time, Zhao Huan sent people to repair the city defense. However, he felt that there was no one in the court's civil and military affairs worthy of entrusting major events, for fear that these people would use this "national project" to corrupt and enrich their personal pockets.

So an eunuch from the palace next to him was sent to preside over this important matter of national defense.

This eunuch was even less than what Zhao Ji of the previous dynasty was. He was honest and devoted himself. He thought that since the official trusted him so much, he had to work hard to complete the task and live up to the high expectations of the official. He considered that the Jurchens came to the south and were the first to be affected.

It is the north city, so the defenses of the city and sloping towers on the back were repaired and the city walls were repaired and heightened. It was just that the other east and west sides were repaired without caring about it at all.

When the Jin army was outside the city of Jianbing, everyone found that the Jurchens came from not only the north, but Jin people were stationed in all the walls of Bianjing. They captured the powerful men and drove them into servants along the way. When they arrived outside the city of Bianjing, they captured the people outside the city as servants.

The stone transports stones, logs, and equipment for preparing to attack the city. People come and go outside the city of Bianjing, and the flags are flying in the cold wind, and it is a busy and bustling scene.

Originally, the city defense was insufficient, but now the city is disabled. Everyone was frightened when watching the city. They felt that the city was hard to rely on. They all felt afraid and blamed the eunuchs for ruining the country and making trouble. When they were building the city, they all blamed the city for not being able to do anything.

I saw it, but no one mentioned it, and no one pointed out its disadvantages. I just don't know if they feel guilty now... (Go
