In the 11th year of the Great Cause of Sui Dynasty (6 15), Emperor Yang Di was besieged by 100,000 Turks in Yanmen (now Daixian County, Shanxi Province). With the help of General Yun Dingxing of Tunwei, Li Shimin proposed an imaginary Zhang Junrong, which led dozens of flags during the day and drummed at night to summon the corresponding suspected soldiers. At that time, reinforcements from Dongdu and various counties also arrived in Xinkou (now north of Xinxian County), forcing Turks to leave after Khan's clearance. In June of 13th year, Li Yuan and his younger brother led the troops to attack Xihe River (now Fenyang), and won the first battle, which prompted Li Yuan to decide to explore the Guanzhong in the west. As the right commander-in-chief, unify the right three armies. In July, I went south with Li Yuan from Taiyuan (now southwest of Taiyuan). On the way, Tang Gaozu once wavered. He wanted to go back to his teacher and make more plans. Shimin insisted on continuing to March and put forward the general plan of entering Xianyang first and ordering the world. In August, when he attacked Huoyi (now Huozhou), he first led a Qingqi to the city gate, lured the Sui Shoujiang Song Laosheng to fight, and then led a ride to his side, cooperated with Li Yuan, built a frontal attack, chopped the Song Laosheng and took the city away. In September, the army arrived in Hedong (now southwest of Yongji), urging the army to quickly enter Chang 'an (now Xi 'an). So he was ordered to lead the former army to cross the Yellow River to the west and successfully occupied the area north of Weihe River. Heroes of all ethnic groups flocked to the military gate to join the army, and several peasant insurgents also joined in, and their strength quickly grew to 654.38+03 million. In November, the army will conquer Chang 'an. Li Yuan made the king emperor. Shimin was named King of Qin.
After the establishment of the Tang Dynasty, Li Shimin was made a senior official and general of Wuhou and became the king of Qin.
After the establishment of the Tang Dynasty, six great battles were fought to unify the whole country. Li Shimin commanded four of the six campaigns, all of which won victories and made great contributions to the Tang Dynasty.
For the first time, it was the battle between Xue Ju and his son in Longyou. In the first year of Tang Wude, when Xue Ju led the army to tackle key problems, the two sides fought fiercely in Changwu County, Shaanxi Province. Here, Li Shimin fought the only big defeat in his life and returned to Chang 'an. But before long, he completely defeated Xue Jun in the shallow water battle and wiped out Longdong Group.
The second time, Liu Wuzhou attached to the Turks, attacked the south of the Tang Dynasty and captured Jinyang. Li Shimin took the bull by the horns and finally defeated the enemy's main force. Two days without food and three days without armor, he completely wiped out the enemy and recovered the lost ground.
The third battle was with Wang and Dou Jiande. The scale of this campaign is the largest in the Tang War. In this battle, the king was defeated first, and Luoyang was besieged, leaving Luoyang without food and grass to wait for his death. Just before the arrival of Luo Yang, more than ten people of Dou Jiande Army in Hebei claimed to be 300,000 to save the king, suddenly appeared behind Tang Jun, parted the crowd, defeated Dou Jiande Army in the battle of Tiger Prison, and captured Dou Jiande alive. Wang had to surrender in Luoyang. This time, Li Shimin took two grams at a time and won a decisive victory.
The fourth battle is to pacify Liu Heita. Liu Heita is a subordinate of Dou Jiande. He fought against the Tang Dynasty in Hebei under the banner of revenge for Dou Jiande. Li Shimin commanded the battle to pacify his first army, and it took only two months to win. (In the other two battles, Li commanded to pacify Du's Jianghuai Army and Liang's regime in Jiangling, Xiaoxian County).
Since then, Li Shimin's prestige has been growing, especially when he entered Chang 'an after the Battle of Tiger Prison, and he was treated like a military and civilian emperor. In October of the fourth year of Wude, he was named General, Leader of Situ and Secretary of Dongdao in Shaanxi, and the food city increased to 20,000. Gaozu also sent a letter to Ce Tian Prefecture to establish his own official, forming a small government organization.
Li Shimin paid attention to pre-war reconnaissance in the battle. Although he was in distress many times, he was able to know himself and know himself, and he was good at making fighter planes. When the enemy is strong and we are weak, he often uses the tactics of "strong wall and weak point" to defeat the enemy. He took the lead and personally led the cavalry to assault the enemy lines. Courageously pursue the enemy after victory, without giving him a chance to breathe, so he will win every battle. In the war to unify the frontier, he strategized, won thousands of miles, knew the generals, selected outstanding talents and won the war. Li Shimin made great contributions to the establishment and development of the Tang Dynasty Empire with his outstanding military talents. He deserves to be an outstanding strategist in the history of our country, and his brilliant martial arts will also go down in history!
As we all know, Li Shimin is a person. No one is perfect, everyone makes mistakes. In the later period of Zhenguan, Emperor Taizong began to have some changes, first reflected in Shangshu. In the tenth year of Zhenguan (636), Wei Zhi found that he "spoke frankly, which was the beginning of some mistakes made by Emperor Taizong.
First, to conquer Goguryeo, some people think it was a wrong move, which was necessary and needed according to the situation at that time. First, Goguryeo is responsible for waging war. Goguryeo brazenly attacked Silla, a vassal state of the Tang Dynasty, and provoked war. In order to maintain his authority, Tang needed to wage war to protect the interests of his vassal States. Second, in the war, Tang Jun is just and human, which is also an external condition to ensure that Tang Jun has little loss. All the cities captured by Tang Jun supported Tang Jun, but in order to maintain justice and humanization, it led to local stability and prolonged the war period. Third, Tang Jun's retreat and the subsequent war fully reflected Li Shimin's mind and superb strategic thinking. Tang Jun wiped out hundreds of thousands of people in Koguryo with a loss of 2,000 people, which is rare throughout the ages. When retreating, the enemy rarely bows to the city wall. Tang Jun's military harassment and political blockade in the later period made Goguryeo's strength go from bad to worse, and finally Gaozong eliminated Goguryeo.
Luxury goods have also increased significantly. In the sixteenth year of Zhenguan, Emperor Taizong wrote that the things used by the prince should not be restricted by other organs, resulting in serious waste of the prince. Emperor Taizong himself began to build palaces. In the eleventh year of Zhenguan, Feishan Palace was built in Luoyang, the eastern capital, and Cuiwei Palace was built in the twenty-first year. These made Tang Taizong less diligent in his later years, but he was many times better than Xuanzong and Qianlong.
