Yelu Xiuge continued to lead his troops to attack, and only then did the Song army realize that it had been surrounded, and it could not resist the onslaught of the Liao army, so they could only retreat one after another.

Jerusha pursued from behind, while the armies of Hugh and Xian also pursued the Song army.

The Song army was defeated, with more than 10,000 dead, retreating south overnight, fighting for the road, and being unable to form an army.

Zhao Guangyi and the generals were separated, and the generals could not find their respective subordinate sergeants.

Zhao Guangyi's close ministers saw that the situation was critical, and in a hurry they found a donkey cart and asked Zhao Guangyi to ride; Flee south.

Jereux was so badly wounded that he fainted and could not ride a horse, so he carried him in light carts on his left and right, gave orders on his behalf, and continued the pursuit.

The Liao army pursued all the way to the city of Zhuozhou, and obtained weapons, sigils, grain and grass, and currency.

After dawn on the seventh day of the seventh month, Zhao Guangyi had already arrived outside the city of Zhuozhou; At that time, the defeat of the Song army had not yet arrived.

He bypassed Zhuozhou City and went straight to Jintaitun, but when he saw that the army had not yet arrived, he dared to stop and "drive" and watch.

On the ninth day of the first month, Zhao Guangyi saw that the army had not yet arrived, so he sent people to explore; Only then did I know that the armies were still guarding Zhuozhou, and there was a plan to establish Wang Dezhao of Wugong County, the son of Taizu, so he urgently ordered Cui Han to pass on the edict to the class teacher.

In order to prevent the Khitan from taking advantage of the southern invasion, Zhao Guangyi ordered Cui Han, the Marquis of Yu, and Dingwu Jiedu to make Meng Xuanzhe to Dingzhou, Heyang Jiedu to make Cui Yan enter Guannan, and Yunzhou to observe Liu Tinghan to make Li Hanqiong to Zhenzhou, and all the above armies were commanded by Liu Tinghan and acted cheaply.

Originally, this was fine, but Zhao Guangyi gave the generals the formation diagram again; He ordered them to enter the Tubu Formation if the Khitan came to attack, and after giving an explanation, he returned south from Jintaitun and returned to Tokyo on July 28.

On the second day of the first month of August, Zhao Guangyi was punished for losing discipline and degraded Shi Shouxin, who stayed in Xijing, to be the envoy of the Chongxin Army; Zhangxin Jun Jiedu made Liu Yu an observer envoy in Suzhou.

At the same time, because of the unfavorable Northern Expedition, even the reward of Ping Taiyuan was exempted.

At that time, many people thought that this would not work, and Zhao Dezhao, the prince of Wugong County, admonished: "You should first reward Taiyuan, and then punish Youzhou for losing discipline." ”

Song Taizong was furious, remembering that the generals had intended to make him the emperor when they couldn't find him, so he said: "Treat you as the son of heaven, it's not too late to reward!" ”

Zhao Dezhao was forced to be self-explanatory, and after returning to the private house, he drew his sword and killed himself.

The Liao army was victorious, but also rewarded and punished. With the right to know the Nanjing left-behind Han Derang, the right to Nanjing Ma Bujun commanded Yelu Xuegu, and knew the third secretary Liu Hong, who could calm the hearts of the people and give the acropolis and give the edict and praise.

In the past, Yelusha was blamed for the defeat of Baimaling, and he offset it with the defeat of the Song army this time.

Jerodhidi retreated when he met the enemy, and struck him with his sword on his back. Although Sahe, the king of the second room, retreated, his troops were not chaotic and were forgiven. King Yelu of Ji died in the battle of Baimaling, and those who fled first under his command were all beheaded, and they were all imprisoned on the back of the staff. Then they gathered together for a feast and gave their rewards.

Song Taizong ascended to the throne of emperor by improper means, which was inevitably criticized by the people.

In order to make up for these shortcomings, he is anxious to create several brilliance.

The destruction of Yang Ye, the general of the Northern Han Dynasty, was indeed brilliant, but despite the fatigue of the soldiers, he attacked Youzhou; Trying to recover Yanyun for sixteen weeks cannot be said to be not a stinky game of chess.

During the Taizu Dynasty, Zhao Guangyi was always the mayor of the capital of Bianliang Prefecture in Tokyo, and he was good at administration and short about the military.

wanted to recover Yanyun's hometown in one fell swoop by destroying the remnants of the Northern Han Dynasty, rebuild the national defense line in northern China, and further restore the position of the Central Plains regime to lead the Siyi; This kind of aggressiveness is beyond reproach and is good.

However, good intentions do not necessarily lead to good results, and the Song army's crushing defeat at the Gaoliang River was not as simple as bad luck.

Zhao Guangyi was carried away by the victory of conquering Taiyuan, underestimated the strength of the Liao army and the fact that it had a large number of cavalry, and hastily dispatched troops in the situation of fatigue and hardship, in an attempt to attack the Youzhou area in one fell swoop with sudden action and superior number of troops. It is only natural that such a reckless and reckless speculative move would be defeated in the end.

From the perspective of operational guidance, the Song army's move to Youzhou was only an attack in one direction; Neither sent troops from the north of Youzhou to cooperate to contain the Liao army, nor did they control a certain reserve force.

From the very beginning, the main forces were thrown into battle, and the attempt was made to achieve a quick victory, and in one fell swoop, it was impossible to save it in the event of a setback.

The second is the underestimation of the defensive strength of Youzhou City, which is a strategic location of Liao; Liao will defend the city with heavy troops.

The Song army advanced rapidly from a long distance and was unprepared for attacking the fortifications, so that the troops immediately fortified the city and fell into the predicament of fatigue of the division.

Finally, there is the lack of reinforcement deployment. Youzhou is a strategic place in Liao, and when it is besieged, the Liao soldiers must be reinforced with heavy troops.

However, Zhao Guangyi was arrogant and did not make any arrangements to block the reinforcements, but only focused on attacking the city with all his strength, resulting in an attack on the Liao reinforcements, resulting in the defeat of the whole army.

On the other hand, although the Liao army suffered some setbacks in the early stage of the Song army's surprise attack, it was able to take some effective measures and wait for reinforcements, which won time for mobilizing reinforcements. After the reinforcements arrived, they successfully used the tactics of encirclement on both flanks, gave full play to the strengths of the cavalry, and took advantage of Yerusha to drag the Song army and weaken the Song army to a certain extent, and suddenly entered the battle, and finally turned the tide of the battle, and achieved the victory of relieving Youzhou and defeating the Song army.

As an important turning point in the relationship between Liao and Song, the Battle of Gaoliang River directly caused the successive defeats of the Song Dynasty in the future, so that the Song Dynasty was completely inferior to Liao, and directly had a great impact on its economy.

Liao became a vast empire that dominated northern China over the Northern Song Dynasty until it was replaced by the Jin.

The defeat in the battle of Gaoliang River was one of the biggest pains in Song Taizong's life trajectory.

The second thing that Zhao Guangyi was very anxious about and very painful was naturally the rumors about his accession to the throne.

Regarding the rumor that Song Taizong improperly ascended the throne, Zhao Guangyi strengthened the unknown spy agency of the Great Song Dynasty, the Imperial City Division.

The Imperial City Division is the Jinyi Guard of Zhu Yuanzhang in the Ming Dynasty, and such a spy organization exists in any dynasty or generation in Chinese history.

The Song Dynasty's spy organization, the Imperial City Division, was directly under the jurisdiction of the emperor, and the main responsibility of the Imperial City Division was to protect the emperor and monitor the hundred officials.

The Imperial City Division is a civil official establishment and is not under the management of the three yas; Rather, they were close ministers directly under the emperor, and most of their heads were eunuchs.

In addition to the duties of guarding the emperor and monitoring the hundred officials, the Imperial City Division was to spy on the dissatisfaction of the common people with the imperial court; Once discovered, secretly executed.

The predecessor of the Imperial City Division was the Wude Division established by Taizu, and at that time he sent people to spy everywhere, even as far as Sichuan.

Emperor Taizong of the Song Dynasty changed his name to the Imperial City Division, and later issued an order prohibiting the Imperial City Division from going out of the capital for activities; Since then, there has generally been no special Imperial Castle Division, and only activities are in the capital.

The personnel of the Imperial City Division are also divided into two parts, one part is called a personal subordinate officer and is in charge of the guards; The other part is called the family officials, also known as the chazi, these people are in charge of all parts of the capital, down to the flower street and willow lane, up to the government ministers, to listen to the big and small news. The number of people has also grown from a few dozen at the beginning to more than 7,000 at the maximum.

The scope of the investigation by the family officer is roughly divided into the following types:

1. Monitor the army. Usually, there are spies from the Imperial City Division in the garrison and even in the squads in front of the palace in Beijing, who record the daily activities and report them in detail, and take emergency measures when necessary. For example, during the time of Renzong, the soldier Sanda and others got drunk and said some disrespectful words, and were immediately arrested by the Imperial City Division and sent to Kaifeng Mansion, where they were executed soon after.

2. Reconnaissance of civil discussions. Song Shenzong changed the law, the court was turbulent, and there were many people who slandered the government. Anyone who heard anyone talking about the government was immediately arrested, and tens of thousands of people were imprisoned for this purpose. At that time, it was even stipulated that at least one detective should be caught every ten days, otherwise he would be beaten (like the current task of the traffic police to fine).

3. Reconnaissance of the activities of officers. There are many officials in this part, from the king's relatives to the warehouses of the various departments, there are fixed people responsible for monitoring. Sometimes, the emperor would also give some temporary tasks. For example, when Taizong suspected that the officials of the granary in the suburbs of Beijing were cheating, he sent the Imperial City Division to infiltrate the reconnaissance in disguise, and there was indeed corruption.

4. Guard against enemy countries. The Song Dynasty was weak, and the Northern Song Dynasty had diplomatic relations with the Western Xia, the Liao State, and the Southern Song Dynasty with the Jin State, and there were many cases of mutual infiltration and spying. The Imperial City Department is responsible for this aspect of security.

5. In the Song system, officials who went to Liao or Jin accompanied by officials from the Imperial City Division; When the envoys of the Liao or Jin kingdoms came to the Song Dynasty, they were also received by the Imperial City Division.

As seen in the records, there is a Zhenzong Huangcheng Division once discovered that a merchant was a spy of the Liao State, so he arrested and brought to justice......
