In 6 14 AD, he married Shi, and on August 2 1 day, Wu De became the queen, the eldest grandson (unknown, married at the age of 13). 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), and Li Shimin was invited to rescue by Yun Dingxing, a general stationed in Tunpu, and proposed an imaginary Zhang Junrong, who led dozens of flags during the day and churned out the corresponding suspected soldiers at night. 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. He was appointed as the right commander, unified the right three armies, and sealed the Dunhuang Duke. In July, I went south with Li Yuan from Taiyuan (now southwest of Taiyuan). It rained heavily on the way, the road was muddy and the food and grass were poor. Ethan once wavered and wanted to return to Li. 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 replaced Wang as Emperor, that is, Emperor Sui Gong, and changed the thirteenth year of Daye to the first year of Yining. General Dr. Guanglu, Tang Gong and Qiu were appointed as fakes, military attache, minister and prime minister inside and outside the viceroy were appointed as Tang Wang, and Qin Gong was renamed Jing. In March of the second year of Yining, he was appointed right marshal and Zhao Gong was transferred.
In May of the same year (6 18), Emperor Yangdi You Yangchan was located in the Tang Dynasty, and Tang Wang Li Yuan was the emperor, and his title was changed to Datang and Yuan Wude. In the first year of Wude, Zhao Gong and Shimin were appointed as ministers and generals, and became the king of Qin. Wude was named General Ce Tian in four years!
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. Li Shimin first hit longyou xue ju father and son group. In the first year of Tang Wude, Xue Ju led the army to tackle key problems. The two sides fought fiercely in Changwu County, Shaanxi Province. Because Li Shimin was ill, Liu Wenjing didn't listen to the marshal's warning, but listened to Yin Kaishan's plan. He went to war, was defeated by Xue Ju, and returned to Chang 'an. But soon, Li Shimin completely defeated Xue Jun in the battle of shallow plain and wiped out Longdong Group.
The second time, Liu Wuzhou attached to the Turks, conquered the Tang Dynasty and captured Jinyang. Li Shimin braved the dangers and finally defeated the main forces of the enemy and pursued them. He didn't eat for two days and didn't understand armor for three days. Eight wins a day, eight wins, completely destroy the enemy and recover 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 a dozen Hebei soldiers in Dou Jiande claimed to be 300,000 to save the king. Suddenly, they appeared behind Tang Jun. Li Shimin pushed aside the crowd and led 3,500 people to defeat the Dou Jiande army in the Battle of Tiger Prison, but Dou Jiande was captured 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 prosperous Tang Dynasty with his outstanding military talents.
The change of Xuanwu Gate took place in Wude, Tang Gaozu (626) on June 4th and 9th. In 6 17, with the support of Li Yuan, he rose up against Sui in Taiyuan and quickly occupied Chang 'an. In 6 18, Li Yuan established the Tang Dynasty and made Li Jian the prince. He said that he wanted to attack Taiyuan, and Li Yuan promised to make him a prince. But after world peace, Li Shimin became more and more famous, but Tang Gaozu hesitated. Prince Li Chengjian immediately joined his fourth brother, King Li Yuanji, to crowd out Li Shimin. Tang Gaozu's indecision also made the decrees of the DPRK and China conflict with each other, which accelerated the confrontation between philosophers. Li was poisoned once. In the ninth year of Wude, the Turks invaded the border. Li Xiang suggested that commander Li Yuanji should go to the Turks to seize the military forces of the King of Qin and prepare to ambush in Kunming Pool. Wang Chang, the head of the Prince's Mansion, told the king of Qin about this secret meeting. At the last minute, Li Shimin decided to strike first. First kill the eldest brother Li and the fourth brother Li Yuanji, which is the famous change of Xuanwu Gate in history. Three days later (Guihai), Li Shimin was appointed as the Crown Prince, saying, "Since the military affairs now, no matter how big or small, I will ask the prince to carry them out, and then I heard." Two months later, Tang Gaozu abdicated and Li Shimin ascended the throne.
