The song dynasty destroyed the southern Tang dynasty, mainly the post-Shu or the southern Han dynasty, which is also ok. More detailed things.

From September of the seventh year of Kaibao in the Northern Song Dynasty (974) to November of the eighth year, during the Northern Song Dynasty unification war, Cao Bin and other naval forces were deployed to cross the river in the southwest of Shengzhou, and Jiangning (now Nanjing, Jiangsu) was defeated by the famous war in the Southern Tang Dynasty.

After the song dynasty destroyed the southern Han dynasty (see the battle of the song dynasty destroyed the southern Han dynasty), the southern Tang dynasty was sandwiched between three sides. Li Yu, the ruler at the end of the Southern Tang Dynasty, surrendered openly and prepared for war in secret in order to protect himself. At the same time, he sent envoys to the Song Dynasty to carry out policy sealing, and deployed troops at various points in the middle and lower reaches of the Yangtze River to prevent Song Jun from attacking. Song Taizu and Zhao Kuangyin, aiming at unifying the south of the Yangtze River, thought that "no one can snore and sleep on the side of the couch" and stepped up their preparations for the battle. In May of the seventh year of Kaibao, he was ordered to build several large ships and yellow and black dragon warships in Jinghu Lake, with the aim of erecting the Yangtze River pontoon bridge. In September, Zhao Kuangyin resigned after Li Yu refused to come to the DPRK, and sent 65,438+10,000 troops. The three roads are neck and neck, competing to attack the southern Tang Dynasty: Qian Chu, the king of the East Road, served as the ambassador to the southeast of Shengzhou, led tens of thousands of soldiers from Hangzhou (now Zhejiang) to the north to coordinate, and sent Ding Deyu, the general of the Song Dynasty, to supervise the army; Cao Bin in the middle road and Pan Mei in the governor's office led a water army of 654.38+ million, advancing eastward along the Yangtze River from Jiangling (now Hubei); Wang Ming, the west road, was deployed as Chachi, crossing the river and occupying the dam to contain the Nantang army in Hukou (now Jiangxi) and ensure the main force to advance eastward.

On October 18th, the seventh year of Kaibao, the Cao Bin Department of the Central Route Army went eastbound along the north bank of the Yangtze River, and ordered Bazo to lead Hao Shourong to follow up. The Southern Tang Army mistakenly made a routine river patrol for Song Jun without any interception, which allowed Cao Binjun to pass the hukou smoothly. On 25th, Cao Bin led an army to capture Xiakou Village (now Guichi West, Anhui Province). On the fifth day of October, I took Chizhou (now Guichi, Anhui) lightly. On the 13th, he defeated Nantang Army in Tongling (now Anhui) and won more than 200 warships. Lianke Wuhu (now Anhui) and Dangtu (now Anhui) defeated more than 20,000 defenders in Nantang at Caishiji (now quarrying in Dangtu North, Anhui), captured more than 1,000 deputy commanders such as Yang Shou and Sun Zhen, and seized the pass. He ordered Hao Shourong to lead soldiers and craftsmen to build a pontoon bridge across the river in Caishiji to ensure that the follow-up troops crossed the river. When Li Yu heard the news, I ordered Zheng Yanhua to go to Zhenhai, with 10,000 pilots and Du Zhen, the commander of Tiande, to stop the attack. He met Song Jun and was defeated in Xinzhai (near Jiangning, Jiangsu) (see Quarrying Battle).

On November 15, the seventh year of Kaibao, the west road attacked Ezhou (governing Jiangxia, now Wuchang, Hubei) and defeated more than 3,000 people in Nantang. The Eastern Route Army besieged Changzhou (now Jiangsu) and captured Licheng Village (now Jiangyin, Jiangsu).

On the eighth day of the first month of the eighth year of Kaibao, all roads attacked on all fronts. Wu Dujiang, commander-in-chief of Huangzhou military forces, captured Fan Shanzhai (present-day western Hubei). Tian Qinzuo, the commander in charge of the left-wing battle in the camp, led the army to attack Lishui (present-day Jiangsu), defeated more than 10,000 Nantang troops and killed Li Xiong. 17, Cao Bin led an army to attack Jiangning, the capital of Nantang. More than 65,438+10,000 people in the Southern Tang Dynasty were defended by Qinhuai River and Jiangning City. In order not to lose fighters, Pan Mei did not wait for ships to cross the river, even if cavalry waded in; Battalion commander Ma Jun led Li to cross the Qinhuai River, and launched a fire attack on Nantang Water Village with a large area of bulrushes, annihilating tens of thousands of Nantang troops and advancing on Jiangning at the gates (see the battle of Qinhuai River). A few days later, the Southern Tang Army fought back again, trying to seize the quarrying pontoon bridge by going up the river, but Pan Mei led the army to break it, and Zheng Bin, the leader of Shenwei Army, was captured.

On the 20th day of the first month in the eighth year of Kaibao, Li was ordered to transport Jinghu commissary to Jiangning for supply to Song Jun. By May, he occupied Yuanzhou (now Yichun, Jiangxi), Bailuzhou (now southwest of Nanjing, Jiangsu) and Jiangyin (now Jiangsu). The East Route Army also captured Changzhou. Wang Ming led his troops to defeat more than 10,000 people in Jiangzhou, Wuchang (now Jiujiang, Jiangxi) and seized 500 warships. Song Jun besieged the city for several months, and Li Yu knew that the situation was critical, so he sent 654.38 million soldiers to help. Zhu Lingyun was afraid that Wang Mingjun would cut off the route for providing foodstuff from behind and did not dare to move eastward.

On the second day of June in the eighth year of Kaibao, Cao Binjun defeated more than 20,000 Nantang troops at the gates of Jiangning and seized thousands of warships. In August, Ding Deyu defeated 5000 troops of Nantang Army in Runzhou (now Zhenjiang, Jiangsu), and joined forces with Wu Yuejun to capture Runzhou City on the ninth day of September. At Li Yu's repeated urging, Zhu Lingyun led an army of 150000 in October, took a 100-meter-long raft and a big ship that could accommodate the drought victims, and set out for the east, trying to break the mining stone pontoon bridge. When the Yangtze River is shallow and the waterway is narrow, large ships cannot parallel; In addition, Wang Mingjun, who was stationed in Dushukou (now near Anqing, Anhui), erected a mast-shaped stake on the river bank, which made Zhu Jun afraid to enter lightly. On the 21st, I arrived at Wankou by ship alone (now southwest of Anqing, Anhui Province, where water entered the estuary), and was intercepted by the Ministry under the command of Song Dynasty, so I attacked it with kerosene, and the wind turned positive. Zhu Jun collapsed without a fight, Zhu Lingyun was burned to death in the melee, Henry Hui Wang and others were captured in the war, and tens of thousands of weapons were captured by Song Jun. 1 1 month 12, Cao Bin's army attacked Jiangning City from three sides, and Li Yu led 5000 people to attack Song Jun North House at night, but failed. On the 27th, Shoujiang, Ma and Ma were killed in the street fighting. Li Yufeng surrendered. Southern Tang Dynasty perished.

Comments: This campaign is the third large-scale river battle in the history of China War, following the battles of Jin and Wu, Sui and Chen. Song Jun successfully built a pontoon bridge in the lower reaches of the Yangtze River, which was a pioneering work in the history of ancient war in China, enabling the army to overcome natural disasters, divide troops to break the garrison in Nantang, capture Jiangning, and make a forced landing in Nantang. Among them, the water army still occupies an important position, and Song Jun started on the 5 th and joined forces. Among them, No.2 is the water army: 1 is the main force, from Jingnan along the river to Jinling. The strategic detour all the way, from the Bianhe River down, through Yangzhou into the Yangtze River, from the south upstream, attacked Jinling, which played an important role in the demise of the Southern Tang Dynasty. History once again proves that in southern operations, in a sense, it is a contest between the water army and the navy. The warring parties, who has a strong water army, who is well prepared for water operations, and who is good at giving full play to the characteristics of the water army's strong mobility in the water network area, will win the war. Jin destroyed Wu, Sui, and Song destroyed Southern Tang. Li Yu, the queen of the Southern Tang Dynasty, relied too much on the natural barrier of the Yangtze River and tried to use the defensive tactics of "strengthening the city walls to learn from the old Song Dynasty". When crossing the river in Song Jun, she missed the opportunity to fight back and eventually failed.
