In the eighteenth year of Zhenguan (644), he decided to personally levy Korea. Many ministers wrote to dissuade them, and Chu Suiliang suggested sending two or three fierce generals to lead 40,000 to 50,000 troops, which could be accomplished without personal expedition. Emperor Taizong refused to listen and said to his courtiers, "Liaodong is the land of China, which the Sui family can't get. I'm going to the East today to avenge China's children. I'm ashamed of your father in North Korea. And although the square angle is big, it is not flat, so I am not old, so I will take it with the power of literati. " In July of that year, General Yan Lide and others were sent to Hongzhou (now Nanchang, Jiangxi), Raozhou (now Boyang, Jiangxi) and Jiangzhou (now Jiujiang, Jiangxi) to build 400 ships and transport rations. Since Hebei Province, the transportation of grain and salary with the Etai Changqing Weiting as the messenger has been subject to its economy. Xiao Rui ordered his servant Shao Qing to transport food and grass from Nanzhou to the sea, ready to attack Liaodong. Zheng is an old minister of Yizhou secretariat. Emperor Taizong asked him because he had attacked Korea from Yang Di. To Japan: "Liaodong has a long way to go, and water transportation is difficult. Dongyi is good at guarding the city and attacking Fukashi." A few short sentences tell the length of both sides and the future of the war. Unfortunately, Emperor Taizong did not seriously consider this point, saying that it is not what it used to be, and it is still sending troops on a large scale. In November, Sean, the minister of punishments, was the general manager of Pyongyang Road March, leading 40,000 strong teams in Jianghuai and other places, and raising 3,000 soldiers in Chang 'an and Luoyang, and 500 warships crossed the sea from Laizhou (now Yexian, Shandong) to Pyongyang. Taking Li Shiji as the chief of the Liaodong Road March, he led 60,000 troops and a part of the northwest Hu Bing to Liaodong, and the land and water armies joined forces. Then Silla, Baekje, Xi and Qidan cooperated with Tang Jun to attack Korea. In February of the 19th year of Zhenguan (645), Emperor Taizong led an army from Luoyang to the front to supervise the war. In April, Li Shiji crossed Liao, and there was chaos in Korea, and all the cities were closed. Li Shiji and Li Daozong conquered Gai City (in Liaodong City, now northeast of Liaoyang, Liaoning Province), captured more than 20,000 people and provided1000 mangoku. Take the land as the cover state. In May, Sean led a boat division to pull out Beishacheng (now Dongda Heishan, Jinxian County, Liaoning Province) and won 8,000 men and women. Both the land and water armies in the Tang Dynasty achieved success. Li Shiji's army went to Liaodong City (now Liaoyang, Liaoning Province), and Korea rode forty thousand soldiers to save Liaodong. Li Shiji and Li Daozong were beheaded by thousands of troops. When Emperor Taizong led his troops across the Liaohe River, he removed the bridge to show his determination. Li Shiji attacked Liaodong City day and night, and Taizong led the troops to meet at the gate. Hundreds of siege, shouts deafening. Tang Jun set fire to the wind. Burning its tower, the fire spread to the city. Enemy at the Gates, the defenders were defeated, and Liaodong declined. If you kill more than 10,000 people, you will have to drop more than 10,000 soldiers and 40,000 men and women, and take its city as Liaozhou. Then he marched into Yancheng (northeast of Liaoyang, Liaoning). Li Simo, the right-back general, was shot by a crossbow, and Taizong was sucking blood. The general of Qi was hit by an army. He was injured and struggled to break the North Korean soldiers. In June, Bai Yancheng fell, with more than 10 thousand men and women, and its city was named Yanzhou.
In June, Emperor Taizong set out from Liaodong and marched straight into Ancheng (now Yingchengzi in the south of Haicheng, Liaoning). Gao Yanshou and Gao led North Korea150,000 soldiers to save the city. It reaches eight miles southeast of the city and is 40 miles long by the mountain. Li Daozong suggested that if North Korea goes to war and Pyongyang's garrison is weak, it is willing to lead 5,000 elite soldiers to take Pyongyang to cover its roots, and the rest can surrender without fighting. Emperor Taizong didn't use his strategy, and personally commanded Li Shiqi, Sun Chang Wuji and other armies to clamor for help. When the thunder and lightning met, Xue was dressed in strange clothes, shouted and was invincible. The army stormed, and North Korean soldiers were defeated, beheading more than 20,000 people. More than 36,800 people surrendered with high longevity and high rate. Emperor Taizong said to the two men, "Dongyi teenagers dance the joy of Liang Hai. As for destruction and decisive victory, they are not as good as the old people. How dare they be enemies with the son of heaven from now on?" In the battle, 50,000 horses, 50,000 cows and 1 10,000 armored soldiers were captured, which shocked South Korea. Xue paid tribute to the guerrilla general. Taizong wrote to the prince and the left-behind minister Gao Shilian, saying, "Why should I do this?"
Emperor Taizong took the city of Anshi as Wei Cheng, and the defenders were good at fighting and defending. He said that Li Shiji said: "Jian 'an (now southeast of Yingkou, Liaoning Province) has weak soldiers and little food. Take it by surprise, then take it by surprise. You can attack Jian 'an first, and then the city will be in my belly. This art of war is called' the city does not attack'. "Li Shiji thought stores are in liaodong. If Yue Annan attacked Jian 'an, he might be deprived of food, so he attacked An Shi first. In July, Taizong moved to the Dongling in the east of Anshi City, and in August, he moved to the south of Anshi City. Korea defended the city and fought alone, and Tang Jun could not attack for a long time. In September, Gao Yanshou and Gao put forward a plan. First, Gu Wu (in the northwest of Dandong City, Liaoning Province) will be captured, and other small towns will be doomed to collapse. Then collect its capital grain and take it directly from Pyongyang. All the ministers agreed. Only Sun Chang Wuji thought that the emperor's personal presence was a foolproof solution. There are still hundreds of thousands of Korean troops in Jian 'an and Xincheng. If you attack the black bone first, it is easy to be attacked between Scylla and Charybdis. It's better to break the city first, then the ancient emperor takes Jian' an, and then drive straight people. The armies continued to storm Anshi, and Governor Li Daozong built a heaped-up mountain in the southeast of the city, several feet above the city wall and overlooking the whole city. Korean soldiers went out of the city to seize heaped-up mountains, but Tang Jun could not attack, and Li Daozong hurt his foot. The climate of Emperor Taizong in Liaodong was cold, the grass was dry and the water was frozen, and the food was exhausted, so it was difficult for the army to stay long. In September, I sent a letter to transfer troops to cross the river. In October, Emperor Taizong came to Chongqing Customs (so the address is now Dongshan Customs, Qinhuangdao City, Hebei Province) and arrived in Youzhou in November. Ten cities such as Xuantu, Gaimou, Liaodong, Baiyan and Beisha were selected, and 70,000 people were registered and 40,000 people were beheaded in the three states of Liao, Gai and Yan. Nearly 2000 soldiers died, 178 horses died. Emperor Taizong deeply regretted it and sighed, "If Kevin·Z were here, he wouldn't let me do anything!" He said to Xue, "I will be old, and the brave will take it." If there is no Qing Dynasty, you don't like Liaodong, but you like Qing Dynasty. "
In March of the twentieth year of Zhenguan (646), Taizong returned to Chang 'an. Although Zang, Aric of Korea, and Gai Suwen, Mo Lichun, both sent envoys to apologize, they invaded Silla. In the twenty-first year of Zhenguan (647), Emperor Taizong wanted to attack Korea again. The courtiers suggested that North Korea is good at guarding the city, but it is difficult to break it in the short term. It is better to send some divisions to attack and disturb it in turn, so that its people can't farm. A few years ago, the people were depressed for thousands of miles, and the north of the Yalu River won without a fight. Emperor Taizong used his proposal. In March, Niu Jinda was the chief of the March on the clear autumn road, leading more than 10,000 people across the sea to attack Korea. With Li Shiji as the chief marching officer of Liaodong Road, he led three thousand troops and Yingzhou generals to attack and disturb by land. In the twenty-second year of Zhenguan (648), Emperor Taizong saw that North Korea was in trouble and prepared to send 300,000 troops to destroy Korea in one fell swoop next year. Some people think that when the army moves eastward, it must prepare food for the elderly, and it is difficult to carry it by land, so it must be carried by water. The people of Jiannan Road (now Chengdu, Sichuan) are rich, so let them build boats and ships. So the Thai faction cut down trees and built ships on Jiannan Road. The largest ship was 100 feet long and 50 feet wide. The three States of Ya, Qiong and Mei, which belong to Jiannan Road, suffered from the shipbuilding war, so they sent, Liang and led twenty thousand troops to rise up and suppress them. Shu people suffer from the battle of shipbuilding, so please hire a shipping agent (one ship, 2,236 silks) to hire Tanzhou people to build ships. "The governors of counties and counties are in a hurry, and the people can't afford to sell their houses and children. The price of the valley is expensive and the sword is arrogant. " In the 23rd year of Zhenguan (649), Emperor Taizong died and the war was temporarily stopped.
In the sixth year of Yonghui in Tang Gaozong (655), Korea, together with Baekje and Mohong, invaded the northern border of Silla and captured 33 cities. King Silla sent a special envoy for help, and the emperor sent Cheng Mingzhen and Su to attack North Korea, killing more than 1,000 people and burning their foreign countries and villages. In the fifth year of Emperor Xianqing (660), Baekje was supported by North Korea and invaded Silla many times. Silla Wang Jin came to the table for help in the Spring and Autumn Period. In March, Su Wei, the general of Zuo Wuwei, was the general manager of Shenqiu Road March, and led the water army to cross the sea to attack Baekje. Take Jin Chunqiu as the chief of snail road March, and lead Silla soldiers to cooperate with the battle. In August, Su defeated Baekje soldiers in the estuary, killing thousands of people, and the rest fled. Tang Jun goes hand in hand with land, pointing to its capital. Baekje went to the country to fight and was defeated, killing and injuring more than ten thousand people. Baekje King Fuyu Yici and Prince Fuyulong fled to the northern border. Sue surrounded the capital, and Fu Yutai, the second son of Wang, became king and led the people to stick to it. The son of Taizilong surrendered on the city, and everyone obeyed. Fuyutai cannot be banned. Tang Jun entered the city, Fuyutai opened the city, and the king, prince and Zhucheng owners all surrendered. With the establishment of Land, Jin Xiong and five other governor's offices, it was divided into five original departments, 37 counties, 200 cities and 760,000 households, and its chief executives were the governor and the secretariat. Liu Ren is willing to stay in Baekje, while the Soviet Union will switch to North Korea. In the first year of Longshuo (66 1), Baekje people rose up against the Tang Dynasty, made the old prince Fu Yufeng king and recovered most of the land. The Tang Dynasty left Liu Renyuan and Liu in Xiongjincheng. In the second year of Longshuo (662), the Soviet Union besieged Pyongyang for a long time, and transferred troops to clear the way. Emperor Gaozong ordered Liu Renyuan and Liu to evacuate to Silla, arguing that "Pyongyang's army is back, and a city cannot be consolidated alone". Liu believes that if we want to destroy North Korea, we must first punish Baekje to contain the enemy. Today, Pyongyang has cleared the team, Jin Xiong has withdrawn, and the embers of Baekje have rekindled. When can North Korea be wiped out? Liu Renyuan and Liu guarded Xiong Jincheng. In the third year of Longshuo (663), he sent his grandson to help him cross the sea. Fu Yufeng, king of Baekje, led the Japanese army to repel Tang Jun, Sun and Liu Renyuan and Liu Huishi. Japanese soldiers fought in Baijiangkou, winning four out of four, burning 400 Japanese ships and the sea was red. Baekje Simomo fled to North Korea, and the prince and others led the masses to surrender. Tang Jun occupied the whole territory of Baekje. South Korea is threatened by Silla, and South Korea is caught between Scylla and Charybdis.
In May of the first year of Ganfeng (666), Gai Suwen of Koryo Spring died, and his eldest son Quan Tongzi left him, while his younger brother Quan Nanjian competed with Quan Nan for power. The man built it himself, so he left him and sent an army to beg the boy. The boy sent his son to ask Tang for help. In June, He Lihe was appointed as the envoy to appease Liaodong, Pang Tongshan and Gao Kan were appointed as the chief officers, led the troops to attack Korea, and made Quan Xiancheng as the guide. Chunzai led the people to see Pang Tongshan. 12, Li Lou was appointed as general manager and appeasement ambassador of Liaodong Road March, Pang Tongshan and Che Qihe were appointed as deputy general managers of Liaodong Road March, and the general managers of the land and water armies were under the command of Li Ji, and the concessions of Hebei States were sent to Liaodong for military use. In September of the second year of dry sealing (667), the new city was conquered, and the whole south was established to send troops to attack, and General Xue Zuo Wuwei broke it. Gao Kan marched into Jinshan, lost the battle, and Korea pursued her victory. Xue Lingbing broke it, beheaded more than 50,000 people, and even joined forces with the whole boy in Zhangzhou and other places. In February, the first year of General Zhang (668), Xue led 3,000 men to attack Fuyu City, which was greatly broken and captured more than 10,000 people. More than 40 cities in Fuyu, Sichuan all surrendered to the wind. In September, Li Dajun advanced into the Yalu River, broke through the Korean defenders, pursued more than 200 miles, and cities along the way fled or surrendered. Li He led his army to the gate of Pyongyang first, followed by Li Ji's army, which surrounded Pyongyang for more than a month. Gao Zang, korean king, sent spring men to yield to the leaders of 1998. Quan Nanjian continued to resist and suffered repeated battles and defeats in the battle. When Tang Jun entered the city, Jeonnam stabbed himself and was captured. The whole territory of Korea is flat. Five departments, 876 cities and more than 690,000 households. There are 9 viceroy offices, 42 states and 100 counties, and the Anton Protection Department is unified in Pyongyang, and its meritorious chiefs are viceroy, secretariat and county magistrate. Right general Xue, guarding Anton, stationed twenty thousand troops.
In the second year of General Chapter (669), the Korean people rose up against the Tang Dynasty and ordered 38,200 Korean people to move to the open space in the south of Jianghuai and Shannan and Jingxi States, leaving the poor and weak to guard Anton. In the first year of Xianheng (670), the leader of North Korea, Kim Mou Lee Cen, established Gao Qiu's grandson Anshun to fight against the Tang Dynasty. Gao Lan is the chief officer of Dongzhou Road. He sent troops to beg for help. Anshun went to Silla, and since then, Gao Kan and Li Jinxing have been fighting in Korea. King Silla Faming not only took in the refugees from North Korea, but also occupied Baekje's hometown and led the people on the Korean peninsula against the Tang Dynasty. In the first year of Shangyuan (674), he was the general manager of Jilin Road, Wei Liu, and was the deputy general manager. He sent troops to attack Silla and Silla sent envoys to pay tribute. In the first year of Yifeng (676), Fu moved to the old city of Liaodong and Du Fu moved to the old city of Jian 'an. In the second year of Yifeng (677), Gao Zang was appointed as the governor of Liaodong, sealed the king of Korea, and sent him back to Liaodong to collect the rest of Korea. Fu Yulong was appointed commander-in-chief of Jin Xiong, and he was awarded the title of King Fang and sent back to Baekje. All under the command of Anton Duhu. Gao Zang rebelled and recalled, but Fu Yu refused and dared not go back to his hometown. Korea and Baekje perished, and Silla gradually unified the Korean peninsula. In the 23rd year of Kaiyuan (735), Silla was sent to the Tang Dynasty, which granted the land to the south of Korea (now Datong River). At the end of the Tang Dynasty and the beginning of the Five Dynasties, the Korean Peninsula was divided into Silla, Korea and Post-Baekje. After the Five Dynasties, Korea and Silla destroyed the post-Baekje and unified the Korean Peninsula.
