The most calm emperor Enemy at the Gates can still be busy with the imperial examination.

Zhao Kuangyin and Li Yu are two famous emperors in history. In many playful TV dramas, the two men fought for women, but in real history, what was the battle between the Northern Song Dynasty and the Southern Tang Dynasty that decided their fate in Nanjing?

after the establishment of the northern song dynasty in Zhao Kuangyin, the southern Tang dynasty was never allowed to exist. Li Yu has long known Zhao Kuangyin's ambition, but he is always humble. Why did he change his mind and make up his mind to fight? When Song Jun crossed the river, he created the pioneering work of a pontoon bridge in the history of ancient war in China. However, in Li Yu's view, this was originally a fantasy, but it gave Li Yu a fatal blow. Why did this idea come from a mole in Nantang? The Southern Tang Dynasty was so cute in front of the Northern Song Dynasty that Zhao Kuangyin couldn't find a reason to attack it. What excuse did he come up with? At the last moment, what kind of painful struggle did Li Yu experience inside? Zhao Kuangyin is a "two-faced man" who has something to do with every ghost.

while adopting the policy of appeasement, we should make strategic arrangements.

In 99 AD, Chai Rong died suddenly, and Prime Minister Fan Ju was ordered to help Chai Rong's youngest son Chai Zongxun become Emperor Gong. In 196, he launched a mutiny in Chen Qiao, raided in front of the house of the regime of the later Zhou Dynasty, returned to the German army, peacefully realized the "Taizu replacing Zhou Dynasty" and established the Song Dynasty, known as the Northern Song Dynasty in history.

subsequently, the domestic political situation was stabilized in less than a year, but outside the jurisdiction of the Song Dynasty, a powerful Qidan Liao State and the Northern Han regime under its control appeared in the north. There are separatist regimes in the south, such as Nanping, which occupies a corner of Jianghan, Wuping, which occupies 14 states in Hunan, Houshu, which occupies 45 states in Hanzhong, Sichuan, Nanhan, which occupies 6 states in Lingnan, Nantang in Jiangnan and wuyue, Zhejiang. In order to end the division of the Five Dynasties and unify the whole country, Zhao Kuangyin is bound to wage a unified war and wipe out the separatist regimes one by one. Therefore, on the basis of adopting the opinions of military commanders, he formulated the strategy of "attacking the north first, and defending the north from the south". From 1963 to 1971, Nanping, Wuping, Houshu and Nanhan were destroyed in the Song Dynasty.

Southern Tang Dynasty is the strongest among southern countries. However, the Southern Tang Dynasty respected the Song Dynasty very much, which made it difficult for Zhao Kuangyin to find a reason to fight. Therefore, Zhao Kuangyin first seized its neighboring countries, forming a situation of surrounding Nantang, and then looked for opportunities and excuses to destroy Nantang. Before the regime of Nanping, Wuping, Houshu and Nanhan was eliminated in the Southern Tang Dynasty, Song Zhao had always adopted a policy of appeasement to the Southern Tang Dynasty, such as making Li Yu's father emperor, allocating food to relieve the famine in the Southern Tang Dynasty, killing the generals who rebelled against the Tang Dynasty, and releasing thousands of troops to the Southern Tang Dynasty. And temporarily win over and stabilize the southern Tang dynasty.

the core of the northern song dynasty's conquest of the southern Tang dynasty was the conquest of Jinling, the capital of the southern Tang dynasty. Zhao Kuangyin's battle plan for attacking Nantang is "East-west attack on Jinling". He appointed Cao Bin as the commander-in-chief, Pan Mei as the deputy commander-in-chief, Cao Han as the pioneer, led hundreds of troops, and besieged Jinling by land and water. Cao Bin led the Jinghu Army down the Yangtze River from the south of Beijing and captured the south bank of the Yangtze River east of Chizhou. Pan Mei marched in Hezhou, preparing to cross the river between Hezhou and Quarry, and joined forces with Cao Binjun to attack Jinling. The capital water army went south from Peishui, entered the Yangtze River via Yangzhou, joined forces with Wu Yuejun to capture Runzhou, and then attacked Jinling with Cao Bin and Pan Meijun. Qian _, King of Wu Yue, commanded 5, troops in wuyue, captured Changzhou from the east, cooperated with Song Shuijun to capture Runzhou, and attacked Jinling. With

Li Yu, the ruler of the Southern Tang Dynasty, was a very unlucky monarch. When he acceded to the throne, the Southern Tang Dynasty had just defeated Huainan, the national treasury was empty, and people inside and outside the court were in panic. Li Yu is weak in character, but he is duty-bound to shoulder the heavy responsibility of cleaning up the mess in times of crisis.

Li Yu knows very well that there will be a war between the Song and Tang Dynasties sooner or later. As for its victory or defeat, it has long been expected. But he still hopes to maintain a temporary peace, at least so that he can avoid being a prisoner in his lifetime. Li Yu adopted the advice of Chen Qiao, the assistant minister, and Zhang Yue, the wife of the civil history, and pursued the strategy of "demonstrating outside, and selecting soldiers inside". On the one hand, Song Tinggong was courteous. When sending envoys to pay tribute, he no longer called himself Tang Zhu Guo, but changed his name to Jiangnan Zhu Guo, changed Tang Guoyin to Jiangnan Zhu Guo, and asked Song Tingzhi to call Li Yu by his first name in the above table. At home, the ritual system was derogated, the imperial edict was changed to religion, the official title was also changed to avoid the same name as the Song Dynasty, and the imperial clan children were reduced to knights. On the other hand, he secretly recruited soldiers to prepare for war. Nantang water village, warships and Bulie river bank form a defense line; Inland cities, repair and reinforcement; In Jinling, a lot of grain, grass and hay were piled up for persistence. In order to solve the problem of military expenditure, he encouraged Hao Minfu to pay for officials, tried to defend the strategic points of the south bank of the middle and lower reaches of the Yangtze River with heavy troops, and prepared to use years of hard work to bring down Song Jun, forcing the Song Dynasty to acquiesce in the situation of Nantang.

Nantang also wrote to Qian _, king of wuyue, saying, "If there is no me today, there will be a king tomorrow?" I wish I could even refuse the Song Dynasty. However, Qian Chu believed that it was necessary to avoid making excuses to attack and destroy wuyue in the Song Dynasty. Therefore, Qian Chu refused Li Yu's request and reported the book to Zhao Kuangyin, saying that he would draw a clear line with Nantang and cooperate with Song Jun's determination to attack Changzhou, the hinterland of Nantang.

In the autumn of p>1974, after Zhao Kuangyin made preparations for the southern expedition, he sent a river gate to send Liang Jiong to Jinling and said to Li Yu, "Now there is a ceremony of burning firewood as a sacrifice." It is actually a sign that Li Yuxian entered the court. Li did not make a clear statement. Soon, Zhao Kuangyin sent Li Mu, a bookkeeper from China, to Nantang to persuade Li Yu to surrender to the Song Dynasty.

Li Yu was going to send ministers to the Song Dynasty, but Chen Qiao and Zhang Yue tried to dissuade him. Chen Qiao said, "Your Majesty and I are under orders from Yuan Zong. If they go today, they will stay. What will happen to the country? Although I am dead, I can't see Yuan Zong in Jiuquan! " Li Yu, inspired by Chen Qiao, refused to enter the DPRK on the grounds of illness. Li Yu is determined to fight the first world war.

Unexpectedly, Zhao Kuangyin ordered people to build a pontoon bridge on the Yangtze River.

Li Yu refused to enter the DPRK on the grounds of illness, and Zhao Kuangyin found an excuse. He sent more than 1, troops and thousands of warships to unite with Wu Yueguo to attack Nantang.

in September, 1974, Pan Mei, the deputy division commander, led the vanguard troops such as Du Fu and others, with the intention of sweeping away the positive obstacles of the main force and seizing the defensive points. In mid-October, the northern song army attacked on all fronts. According to the command of the head coach Cao Bin, all the big and small ships made by the Eight Commanders Hao Shoujiang in Jing, Hunan, Shu and other places sailed for Huangzhou, Hubei, and assembled in the river section. Cao Bin led the water army from Jingnan and went down the river along the north bank of the Yangtze River. Eight ambassadors, Hao Shou, led the boats and components used in the pontoon bridge, and then followed suit, successfully passing through Hukou, a strategic place where 1, troops were stationed in the Southern Tang Dynasty. On October 24th, Xiakou Village captured Song Jun, and went hand in hand by land and water, taking Chizhou directly. Jump on

It is unprecedented for Song Jun to build a pontoon bridge on the Yangtze River. When Li Yu heard the news, he asked Zhang Yue. Zhang Yue replied: "Changjiang has not done anything for Liang since it was registered." Li Yu felt a little relieved and said, "I think it's a joke, too." However, the Southern Tang Dynasty was superstitious about old experience, and this time it suffered a big loss.

Speaking of which, things were defeated by a loser named Fan Ruoshui in the examination room, who was from the Southern Tang Dynasty. Fan Ruoshui bears a grudge because he is not the top scholar. Knowing that the Northern Song Dynasty was going to cut south, he disguised himself as a fisherman in advance and traveled back and forth across the Yangtze River in historical records. After measuring the width, depth, velocity and geology of the river, he ran to the capital of song dynasty and presented a pontoon bridge to Zhao Kuangyin, ready to cross the river. According to the plan, Zhao Kuangyin built thousands of yellow and black dragon boats in Jiangling ahead of schedule, and prepared bamboo ropes and components. By the time of the Southern Expedition, it was transported downstream to Shipaikou by Cao Bin Water Army, and after being built into a pontoon bridge, the whole bridge drifted to Caishiji. It was early winter, and the Yangtze River was very dry and the water surface was very narrow, so Song Jun spent three days erecting and fixing the pontoon bridge on the quarrying river. Pan Mei led his troops to cross the river from the north of the river via the pontoon bridge, and they were on the ground.

Li Yuwen learned that Zheng Yanhua, the special envoy of Zhenhai, was sent to supervise 1, naval divisions, and all Hou Yudu led the way and rode 1, people to Caishiji in an attempt to seize and destroy the pontoon bridge. Due to the uncoordinated serenade, Zheng and Du were defeated by Song Jun. Pan Mei led a brigade to ride across the river from the pontoon bridge in Jiangbei, and joined forces with Cao Bin's main force to advance into Jinling. At the same time, Wu Yueguo also sent troops westward to attack Changzhou, Xuancheng and Runzhou.
