The process of Baijiangkou campaign

In 645 AD (the 19th year of Zhenguan), Emperor Taizong of Li Shimin made a personal expedition, led an army of 60,000 and a water army of 40,000, and sent troops from Silla, Qidan and Xi to attack Koguryo. When Tang Jun first entered Jack, he successively conquered Gaimou City (now Gaiping, Liaoning Province) and Shabei City (now Fuxian, Liaoning Province), and captured the fortified city in Liaodong (now Liaoyang, Liaoning Province). Soon, Tang Jun was trapped in Baiya City (now East Liaoyang) and headed for Anshi (now Northeast Gaiping, Liaoning). General Gao Yanshou of Goguryeo and others led Goguryeo and150,000 soldiers to come to the rescue, which was greatly broken by the design of Emperor Taizong. When Gao Yanshou surrendered, he learned that all the generals had surrendered and climbed into Yuanmen to beg for mercy. Taizong thundered: "Don't you dare to make trouble with the son of heaven in the future!" High longevity is "difficult to sweat."

Goguryeo shocked the whole country, the wall fell clear, and the front line tightened to the rear. The Imperial City (now Liaoyang, Liaoning) and Yin Cheng (Tieling, Liaoning) were suddenly empty.

When Tang Jun entered the city for an Anshi, the city was surrounded by dangers. Koguryo soldiers in the city saw the flag of Taizong Yizheng and dared to take the city for a noisy demonstration. Taizong was furious. Li Ji was very angry, too, and advised Taizong that on the day of the gate, all the men who fought were slaughtered. An Shi's defenders heard the news, "so they fought to the death."

After several days of stalemate, the city could not stand, and it was freezing. Taizong cherished the lives of the soldiers and had to order the team to move. Anshicheng was actually a vassal of Koguryo, and Gai Suwen sent troops to attack it after he came to power. "You can't attack it, so." The land is dangerous, people fight for life and death, and it is freezing in the cold. No matter how strong the soldiers were in the Tang Dynasty, there was nothing to show. Before leaving, Anshi City "held its breath and suppressed the flag", and the Lord went into the city to worship. Although Koguryo defenders were not attacked and slaughtered, they also knew Tang Jun's bravery. "Emperor Taizong kept it and gave it a hundred silks."

In 648 AD (twenty-two years of Zhenguan), Emperor Taizong prepared to assemble 300,000 troops, with Sun Chang Wuji as the commander in chief, and wiped out Goguryeo in one fell swoop. Unexpectedly, Emperor Taizong died of illness and Goguryeo escaped again.

In 655 AD (the sixth year of Emperor Gaozong Yonghui), Silla complained to Tang Ting, and Koguryo, Baekje and Xiongnu captured more than 30 cities in Silla. Tang Ting sent a letter to make peace and refused to listen. As an arbitrator of the imperial court, in 660 AD (the fifth year of Guangxu in Qing Dynasty), the left general Su and others were sent to attack and discuss. At that time, the Tang Dynasty had just captured the West Turkic Khan Ashnahulu and divided the West Turkic into two parts, with Hannah Quinlivan and Mengchi as the satrap. With the settlement of the North Turkic issue, the Tang Dynasty naturally catered to Goguryeo and Baekje who jumped up and down on the Korean peninsula.

Encircle Wei to save Zhao, break one side. Tang Jun did not directly rescue Silla, but concentrated on cracking down on Koguryo's accomplice Baekje. Like Koguryo, Baekje "planted other species to help others". The king at that time was Fuyu Yasi. Tang Jun crossed the sea from Chengshan (now Rongcheng, Shandong Province), defeated the Baekje Army in Jinxiongkou, captured Zhendu, wiped out the main force of the Baekje Army, and "beheaded more than 10,000 people and seized its city". The Baekje King Fuyu Yici and the Prince Fuyu Long fled and fled to Beibi Town, surrounded by Sue and Tang Jun. Fuyu Yici's second son Fuyu Yitai had a big idea. He took advantage of his father and brother to escape, became king on his own, and led his people to stick to Baekje City. Fuyu Siwen, the grandson of Fuyu once, said to the people around him: "Now that the king and the prince are here, Uncle Wang is his own king. Even if Tang Bing retreats, my father and son will be killed by Uncle Wang! " In desperation, Fu Yu's literary thoughts led him to "go out of the city". As soon as the city people saw Wang's grandson, they all followed, and Fu Yutai couldn't stop killing several people. Helpless, Fu Yutai came out and Baekje Capital fell. Soon, Tang Jun arrested the son of Baekje Wang Fu and 58 Baekje chiefs, all of whom were escorted to Chang 'an. "The department of King Pingqi has 760,000 households in 37 counties and 300 cities."

In the Tang Dynasty, Jin Xiong and Mahan were founded in Baekje, and their chief was elected as the ruler. In the same year 10, a group of prisoners were taken to the capital, and they were "released without punishment". It's unlucky to be rich once. It turns out that this person is filial and has a good reputation. He is called "Haidong Ceng Zi". Before the war, Tang Gaozong also issued an imperial edict urging that ... what the king owned and what the city owned should be returned (Silla), and what Silla captured (Baekje soldiers) should only be returned to the king. It is better to let the imperial edict be the king's decisive battle, and I will send the Khitan kingdom and go deep into the Liao country. Wang Kesi has no regrets. "King Baekje always thought that Tang Bing would not take it lightly and continued to be an accomplice of Koguryo. Unexpectedly, when Su's generals came out, Baekje was immediately smashed to pieces, and he himself was captured alive, and thousands of miles were blamed on Chang 'an. Before long, Fuyu died of a disease, bite the hand that feeds him, gave Wei Yi a generous gift, and allowed his captured veteran to mourn, "burying Sun Hao and Chen's tomb left"-a meaningful move, just like surrender, which saved him from violent death.
