The video connects all dynasties, starting with an inventory of the top ten emperors

[In the fifth year of Taiping Xingguo (980), Yang Ye and Pan Mei attacked the Liao army successively, achieved the great victory at Yanmen Pass, and defeated the Liao army's offensive from the western front.

In this battle, Yang Ye only led thousands of cavalry to defeat tens of thousands of soldiers and horses of the Liao army. He beheaded Liao Liao's son-in-law and the Jiedu envoy of Datong Mansion Xiao Duoli, and captured Li Chonghui, the commander of the horse infantry. After that, Yang Ye's reputation spread far and wide. , making the Liao people fearful. 】

Zhao Guangyi: "Okay, Yang Ye lived up to my expectations. This time the Northern Han Dynasty was pacified, and it is my greatest gain to have Yang Ye."

[In the seventh year of Taiping Xingguo (982), Yeluxian, the leader of the Liao Dynasty, passed away, and his eldest son Yelulongxu came to the throne.Because the Lord of Liao was young, Empress Dowager Xiao, who once handled government affairs on behalf of her husband, officially regented.

Li Longji: "This plot seems familiar..."

In the third year of Yongxi (986), Zhao Guangyi deeply felt that the leader of the Liao Dynasty, the Shaoguo, had an opportunity to take advantage of it, so he once again recruited soldiers and horses, sent troops to the Northern Expedition, and captured the sixteen prefectures of Youyun.

Zhu Yuanzhang: "Empress Dowager Xiao has been dealing with government affairs since Yeluxian became unwell, and with the help of Han Derang, Yelu Xiezhen and others, the country is basically relatively stable, although it is not monolithic.

This is also Zhao Guangyi's failure. Instead of hoping that the enemy will be weak, it is better to prepare the Song army well. "

In this dispatch of troops, Song Ting set up an army of overwhelming power and divided the troops into three groups.

Pan Mei and Yang Ye led the West Route Army to capture the states behind the mountain. Tian Zhongjin led the Middle Route Army to attack Feihukou and cut off the connection between the states in front of the mountain and behind the mountain. Cao Bin and Mi Xin led the main force of the [-] Song Army to capture Youzhou and other The Piedmont States. 】

Through the previous video and the corresponding biographical video, people from other planes also knew that the Song Army did not take back the Yanyun area through military means.

In other words, Yongxi's Northern Expedition, which was very powerful, failed in the end.

But looking at Song Ting's all-powerful soldiers going north, east, middle and west, it seems that there is no haste in the first Northern Expedition.

Others were really curious about how the Northern Expedition failed. They looked at the map in the video and analyzed the strengths and weaknesses of the Song and Liao armies.

Ying Zheng: "Song's army marched in three ways, logically speaking, there should be some effect. How do you feel that this time it is still a big defeat!"

Li Shimin: "The Song army marched in three directions, attacking the states in front of the mountain and behind the mountain separately. The strategy is quite satisfactory, but I am afraid that they will be defeated by the Liao army one by one.

Once the Liao army took the initiative, the slightly less mobile Song army would be very dangerous. "

[Zhao Guangyi adopted a strategy of attacking the west for the Northern Expedition, ordering the East Route Army to slowly advance to attract the main force of the Liao Army.

Li Shimin: "Huh? If that's the case, the distribution of troops for the East Route Army is a bit too much. The West Route Army and Central Route Army with limited troops may not be able to break through the prefectures behind the mountain as planned."

During this Northern Expedition, Pan Mei and Yang Yebu of the West Route Army broke through all the way and captured the four prefectures of Shuo, Huan, Ying, and Yun on the south line behind the mountain. Tian Chongjin of the Middle Route Army captured Feihu and Lingqiu. The bloody battle also captured Zhuozhou.

Liu Xiu: "The cavalry of the Liao people has mobility, and the Eastern Route Army may be strangled if they are not careful on the plain. I just don't know how well Cao Bin is capable of commanding troops."

Zhao Kuangyin: "It seems that after the last Northern Expedition, the Liao Kingdom has already filled the Youyun area with heavy troops, and the cities in the Youyun area will never be as easy to seize as last time."

Zhu Yuanzhang: "During the Northern Expedition in the fourth year of Taiping Xingguo, the Song army marched to the city of Youzhou in four days and four nights. Fortunately, this time, it was directly stuck on the front line of Zhuozhou."

Zhongjun Tian Chongjin and Jing Si defeated the reinforcements from the Liao State, and captured Yuzhou after a bloody battle. However, the Eastern Route Army fell into a stalemate at this time. 】

Li Shimin: "Too bad, the Song army has lost the opportunity, the main force is suppressed in Youzhou, and the other two routes have not completely captured the states behind the mountain. If all the states behind the mountain cannot be captured, these states will be left alone Outside, I probably thought of the reason for this failure."

[Eastern Army Cao Bin and the Liao Army fought fiercely on the front line of Zhuozhou, winning and losing each other. The Song Army was forced to run out of food, and Cao Bin led his troops back to the division.

After that, Cao Bin couldn't control the generals. Due to the achievements of the West and Middle Route Army, the Song Army on the East Route went north again rashly.

The Eastern Route Army suffered tens of thousands of casualties and was completely defeated. The loss of military resources is difficult to measure. 】

Liu Che: "What kind of battle is this? This Cao Bin is too bad!"

Li Shimin: "Since the Song army has launched an all-powerful army this time, after the defeat this time, I am afraid that Song Ting will never have the opportunity to go north to fight the Liao people."

[Reinforcements from the Liao army gradually rushed to the states behind the mountains, and the Liao army regained Weizhou in World War I.The Song army began to retreat in an all-round way, and Pan Mei and Yang Ye of the West Route Army collected all the people from the four states behind the mountains and returned south.

Liu Xiu: "Well, if we want to lead the people to retreat south at the same time, how can the Song army on the west route surpass the Liao army? The army on the east route has already been defeated, and the army on the middle route has been defeated. If the army on the west route is also defeated, I think it will The Song Dynasty should perish."

When the army was retreating, Zhang, the proprietor of Yang, avoided fighting with the Liao army and led the people to retreat to Yanmen Pass as soon as possible. However, the supervisor Wang Yu and others thought that Yang Ye was too cowardly, and he only wanted to escape when he clearly led the soldiers.

Stimulated by Wang Yu's constant words on the grounds of "surrendering generals", Yang Ye, who is a surrendering general, could only send troops angrily.

Afterwards, Pan Mei, Wang Yu and others commanded troops to meet Yang Ye in Chenjiagu, and Yang Ye returned to attack Yelu Xiezhen. Yang Ye was deeply encircled.

In the battle of Chenjiagu, Yang Yebu was completely wiped out by the Liao army, and Yang Ye died of a hunger strike after being captured alive.

Zhao Kuangyin: "This king should be killed, and Pan Mei and Cao Bin shouldn't be so bad at commanding troops. One can't control the generals in the army, and the other is directly suppressed by the supervising army. Alas..."

So far, Yongxi's Northern Expedition to the Song Army has been defeated in all three ways, and the loss of soldiers and generals will be useless. After that, Song Liao's offense and defense have changed, and the Song Army has no ambition to go north! 】

Hu Hai: "From this point of view, Pan Mei is more or less responsible for this Chenjiagu battle, and this person is a bit disloyal."

Zhao Kuangyin: "So that's the case. After this battle, I, Song Dynasty, probably don't have the ability to go north to fight again."

In the fourth year of Taiping Xingguo (979), Zhending Prefecture, Hebei.

After watching this video, Zhao Guangyi became even more flustered after knowing that he had failed to conquer Youzhou with an all-powerful army.

He kept cheering himself up: "This time, I raised a large army to go north, and the Liao army has not deployed heavy troops in Youzhou. In addition, I have already sent people to infiltrate Youzhou. To be able to catch the Liao people by surprise..."

"Yes, as long as you win this time, nothing else matters."
