After fierce battles, the Ming army and the east and west capitals of Annan, the people of Annan collapsed, and the prefectures and counties paid money to the Ming army. The Hu family and his son lost their ground, but they burned the palace room, died in the sea, and continued to be the enemy of the Ming army. In 1407, the Ming army advanced by land and water, and the Qing Yuan Bo Wang You and others led the army to cross the Zizhu River, broke through the Zhuzhai of the Chipjiang River, the Trapped Piece, the Ten Thousand Tribulations, and the Pulai Zhuzhai, and beheaded more than 37,000 people. Hu Du, the general of Annam, gathered sailors to defend the dangerous Pantan River, and Zhang Fu ordered the general Chen Feng to attack, defeated him, and captured his boat, and then decided on Dongchao and Langjiang Prefectures. The main force of the Ming army pursued to the other side of the Mumaru River, Hu Cheng, the son of Hu Yiyuan, came to fight with 300 warships, the Ming army met the head-on, beheaded 10,000 people, captured more than 100 generals, drowned no one, and the river was red. Zhang Fu built a city in Xianzi Pass and ordered the governor Liu Sheng to guard the town. In March, the remnants of the Annan army fought in the Fuliang River, Zhang Fu and Mu Sheng fought on the shore, Liu Sheng rushed through his formation with a water division, defeated the enemy, beheaded tens of thousands of people, because of the drought and shallow water, the Annan soldiers abandoned the boat and fled, the Ming army chased when the river suddenly rose sharply, so they took advantage of the victory and rushed forward, and most of the Annan soldiers were annihilated. In May, the Ming army pursued to the Qiluo Haikou in Ninan Prefecture, the remnants of the Annan army were annihilated, the Hu father and son escaped only by a few boats, the Ming army with the assistance of the local people, captured Hu Yiyuan and his son Hu Cheng, and then captured Hu Hancang and the pseudo-prince Hu Rui, all of them were sent to Beijing.

At this point, only one year after the Ming army was dispatched, it won a complete victory, eliminating the usurping Hu regime, with 48 prefectures, 180 counties, and 3.2 million households. Zhu Di was greatly delighted, and the ministers also congratulated him and said: "The father and son of the thief violated the heavens and disobeyed the fate, and now they are all arrested, all by the holy virtue and the heavens, and the gods and men help the obedience." Zhu Di said: "The spirit of the ancestors of heaven and earth is caused by the soldiers' lives. The Ming Dynasty monarchs and ministers, who were carried away by the victory, changed their original intentions at this time, and no longer looked for the so-called sages of the descendants of the Chen family, but sought to open three divisions and counties in Annam. On June 1, Zhu Di told the world with the edict of Ping'an Nan, changing Annan to the political envoy of Jiaozhi, Lu Yi as the commander, Huang Zhong as the deputy, Huang Fu as the political envoy and according to the inspector, and set up officials, changed 17 prefectures, since then Annan officially became an administrative region of the Ming Dynasty. After Zhang Fu's class returned to Beijing, Zhu Di gave a banquet in Fengtian Palace, and Jin named Zhang Fu as the Duke of England, with 3,000 stones.

The reason why the Ming army was able to successfully pacify Annan was mainly because the Hu regime was harsh and the people did not adhere to it, Zhu Di was invited by Chen Tianping to hang the people and kill the people, save the people from fire and water, and promised to reinstate the sages of the descendants of the Chen family, which was of course welcomed by the people of Annan, and it was also a righteous move, but after the victory, he went back on his word and hastily decided to subordinate Annan, which was an obvious mistake. Throughout the Chinese dynasties, although Annam has become a Chinese territory many times, but since the five dynasties of Wu Quan, has become an independent country, once directly under the management of China, it will inevitably be resisted by the people of all walks of life in Annam, and Annam can be said to have entered an eventful autumn since then.

Zhu Di was very tolerant of the Hu father and son, and only imprisoned the two of them and a few close ministers, and Hu Cheng, Hu Rui and others were pardoned, but Zhu Di's appeasement did not calm Annan. In 1408, Zhang Fu's army had just been divided, and the local forces in Annan represented by Jian Ding, Deng Xi, Ruan Shuai and others rebelled, attacking Pantan and Xianziguan, and controlling the traffic of Sanjiang Province. After Jian Ding raised troops, he proclaimed himself the king of Rinan, and then in order to attract people's hearts, he set up the so-called Chen Ji, a descendant of the Chen family, as the emperor of Dayue, and changed the Yuan to regain light. Chen Jikuo played the signboard of Chen's descendants and won the support of the people of Annan.

Originally, Chen Jikuo sent people to the Ming Dynasty in the name of the Chen clan to ask for the title, but he was killed because the envoy was rude and angered Zhu Di. Zhu Di, with the support of Zhang Fu, adhered to the policy of attacking by force, and transferred a total of 40,000 people from Yunnan, Guizhou, and Sichuan to command the envoys and the three guards in Chengdu. In December, Mu Sheng fought fiercely with the rebels of Annam in the Shengju River, and suffered a crushing defeat due to the light enemy, Liu Jun, the secretary of the military department of the counselor's military affairs, failed to break through the siege and died by himself.

In February 1409, Zhu Di had no choice but to use Zhang Fu's division again, and sent 200,000 troops to fight with Mu Sheng.

Soldiers are in trouble

Zhang Fu, who "came again in the past and is here today", was already in a good position about the situation in Annan at this time, and he was not in a hurry to move forward, but was cutting down wood and building boats in the mountains to "forgive the people who avoided the Kou in Jiangbei to resume their business." After the situation stabilized, Zhang Fucai led a large army to Cilian Prefecture, broke through the Menjiang River, conquered Kongmuzha in Guangwei Prefecture, and defeated the Annan army at Xianzi Pass. The Annan rebel army gathered more than 600 warships and retired to the southeast bank of the river. Zhang Fu led his generals Chen Xu and others to attack with naval divisions, rode the wind and set fires, broke the crowd, and captured more than 200 of his generals. Pursued to Taiping Haikou, Annan general Ruan Jingyi met the battle with 300 warships, and was broken by the Ming army. In November, Zhang Fu took advantage of the great victory over Yu Wei, sent the commander Zhu Rong, Cai Fu and other infantry cavalry advanced, since the Zhou division as the successor, from the Huangjiang River to the Shentou Sea, the division in Thanh Hoa, and then parted ways into the Lei River, repeatedly defeated the rebels, captured the culprit Jian Ding alive in the Meiliang Mountain, and sent to the Beijing Division together with his henchmen, in January of the following year, Zhang Fu leveled the chaos in other places, beheaded thousands of people, and built the Jingguan to subdue the people of Annam. Chen Jikuo retreated to Tun Yi'an and continued to resist, and Zhang Fufei won the victory to the imperial court. At that time, the first northern expedition of the Ming army happened to encounter a major setback, and Qiu Fu, the prince of Qiguo, Wang Cong, the marquis of Wucheng, Huozhen, the marquis of An'an, Wang Zhong of Jing'an, and Li Yuan, the marquis of Anping, led an army of 100,000 troops to the north to conquer Benyashili, but was ambushed by the Mongol army at the Yuqu River, and Qiu Fu and others were all killed. Zhu Di was shocked, and saw Zhang Fu win,

Thinking that Annam was not enough to cause trouble, he recalled Zhang Fu and prepared to personally lead a large army north to Mongolia. In 1410, Zhu Di personally conquered Mobei and returned victoriously, Chen Jikuo took the opportunity to send the envoy Hu Yanchen into the congratulatory and asked for the title, Zhu Di was happy for a while, and specially awarded Chen Jikuo as the political envoy of Jiaozhi, and his subordinate officials were assigned the positions of commander, political participation, etc., but Chen Jikuo's original intention was to be crowned the king of Annam, Zhu Di's edict could not satisfy him, so he continued to call the army a rebellion. Due to the northward movement of the main force of the Ming army, Mu Sheng, who stayed behind, was insufficient and could not pacify Chen Jikuo. In 1411, in order to completely quell the rebellion in Annan, Zhu Di, who had already freed his hands, ordered Zhang Fusan to conquer Annan, forcing "Chen Ji to expand his table and play the crime", and if he did not admit the crime, he would use force to pacify him.

The people of Annam were quite jealous of Zhang Fu at this time, and the arrival of heavy troops in the Ming army, the situation began to change in favor of the Ming army. When Zhang Fu arrived, he first affirmed the military order, and the governor Huang Zhong had always been arrogant and repeatedly violated the moderation, and Zhang Fu beheaded him with favoritism, so the officers and soldiers were vigilant, and no one dared to use his life. In July, the Ming army broke the Annan general Ruan Jingyi in the Yuechang River, captured more than 100 warships, captured Marshal Deng Zongji and others of Annan, and captured several other generals. In August of the following year, the Annam rebels divided into three teams with more than 400 warships and invited the Ming army to attack the Ming army in the Shentou Sea. Zhang Fu rushed to its backbone with a sharp pawn, and the Ming army implicated the enemy ship with a hook, fighting to the death, fighting fiercely from noon to evening, breaking the enemy army, and taking advantage of the victory to enter Chen Jikuo's old nest Yi'an Mansion, and the soldiers and civilians of Annam surrendered one after another.

In the winter of 1413, Zhang Fu and Mu Sheng joined forces in Shunzhou and fought a decisive battle with the Annan army at the Aizijiang River. In this battle, the Annan soldiers still took the elephant array as the forerunner, and the Ming army shot down the elephant slave with one arrow and pierced the elephant trunk with two arrows, and the elephants all ran back and ravaged the crowd. The Ming army generals Yang Hong, Han Guang, Xue Ju and others took advantage of the situation to advance, but the arrows fell like rain, and the Annan soldiers were defeated. In January 1414, the Ming army entered Zhengping Prefecture, the remnants of the Annan army Tun Xianman, Kunpu Zhuzha, the cliff side path is narrow, the cavalry is not allowed to advance, the Annan soldiers thought that the Ming army would not dare to advance lightly, and Zhang Fu and the general walked on foot in the mountain, and the four drums in the night covered its nest, unexpectedly broke the Annan army, captured Ruan Jingyi, Deng Rong, etc. Chen Jikuo was defeated in Laos alone, Zhang Fuming commanded Shi You to lead the troops to pursue, broke through three passes in Laos in a row, and finally captured Chen Jikuo alive in Mengxi Nanmo, and sent him to Beijing with his wife. At this point, Annan was all pacified, Zhang Fu took the city occupied by the rebels, set up Sheng, Hua, Si, and Yi four prefectures, added guards, and left the army to defend and return, which was the eve of Zhu Di's second expedition to Mongolia.

Under the military suppression of the Ming army, although Jiaozhi was pacified again, the officials of the Ming Dynasty were not good at appeasement, and there were intrigues inside, and the people of Annam were not attached, which laid the root of the subsequent chaos. In January 1418, the Tuguan Governor of Ole County, Thanh Hoa Prefecture, Annam, convened all the tribes to meet in Lanshan and raised troops to resist the Ming, which quickly formed a trend of burning the plains, and the Ming army was unable to suppress it. In 1416, Zhu Di moved the capital to Beijing, and the focus of the Ming Dynasty gradually shifted northward, and Jiaozhi became a heavy burden.

The Kingdom of Lê became independent

In 1414, after Zhang Fu pacified Annan for the third time, the Ming court recalled Huang Fu, and Chen Qia, who was known as the famous secretary of the military department, was the political envoy and the envoy of the military department, and the counselor of military affairs, but the lieutenant Ma Qi appointed by Zhu Di was greedy and violent, and he was harsh in Annan, Chen Qia could not stop it, and the Rongchangbo Chen Zhi and the governor of the town were not harmonious, so that rebellions were raging in various places, and Li Li was even more cunning and difficult to control. At that time, Zhu Di was dead, Xuanzong Zhanji was in power, and Chen Qia said: "Although the thief is begging, he is deceitful inside, and the party is gradually flourishing, and it will be uncontrollable." Tell the generals to destroy the thieves quickly, and they will not be baitted. Xuanzong issued a decree to take responsibility, and Chen Zhi and Fang Zheng were forced to enter the army, but they were defeated in Chalong Prefecture, and the two of them were cut off. After Li Li raised the army, the power developed rapidly, and the Ming army could not be controlled, so in October 1426, Ming Xuanzong ordered Chengshan Marquis Wang Tong to be the general of Zhengyi, and the governor Ma Ying to lead 50,000 troops to help, and the original garrison of Ma Qi was 100,000 to encircle and suppress. At that time, Li Li's brother Li Shan attacked Jiaozhou City, was defeated by Chen Jun, the governor of the Ming Dynasty, and others, in November Wang Tong's main force arrived, parted ways, and the general Ma Ying defeated the Annan army in Shimur County, Wang Tong led the army and Yinghe, and the Ming army advanced to Yingping and Ningqiao. Li Li feinted defeat and set up an ambush, Chen Qia took the situation in this place as dangerous, and he was afraid of an ambush, so he suggested that he should advance slowly. Wang Tong relied on the soldiers not to listen, and his troops crossed and fell into the quagmire. Li Li's ambush troops were launched, and the Ming army was defeated, with more than 30,000 dead. Liu Qia jumped into the battle straight on his horse, his body was wounded several times, and he wanted to help him back, Chen Qia roared angrily: "I am the minister of the country, I have eaten Lu for 40 years, and I serve the country today, and I am obliged to make a living." "Kill several people with a knife and kill yourself.

In the Battle of Ningqiao, Wang Tong was also injured and led the remnants of the army back to Jiaozhou. Li Li besieged Yi'an with heavy troops, Ming Shou general Governor Cai Fu did not come with reinforcements, retired to Dongguan, thousands of households Bao Xuan surrendered to Li Li with his people, Cai Fu was also captured, all commanded Zhou An, commanded Chen Linning to die and did not surrender, led the troops to retreat to Fuliangjiang, surrounded by Annan soldiers, the two shouted "My Son of Heaven courtiers, how can you die thief hand", several people with blades, and more than 9,000 people were killed at the same time.

Li Li gathered 300,000 people to confront Wang Tong in Jiaozhou, and sent the generals out to plunder the land, all of which were destroyed, only the city of Qinghua was still in the hands of the Ming army, and the defender Luo Tong and the commander were loyal to hold on, and the Annan army could not be attacked. In February of the following year, Li Li attacked Jiaozhou, Wang Tong took advantage of his unpreparedness, smashed his camp with 5,000 soldiers, broke it, beheaded more than 10,000 levels, Li Li panicked and retreated. The generals of the Ming army asked to take advantage of the victory to pursue, but Wang Tong was as timid as a mouse, and did not come out for three days, and a few days later Li Li regained his momentum, and then besieged Jiaozhou, divided his troops to capture Changjiang and Langjiang, and the situation took a sharp turn for the worse. Wang Tong was terrified, and on the one hand, he contacted Li Li, promising to ask for a feudal feud on his behalf, and on the other hand, Feizhang asked the imperial court for more troops. Ming Xuanzong ordered Liu to be promoted to the deputy general of the conquest and the general officer, Baoding Bo Liang Ming was the left deputy commander-in-chief, the governor Cui Ju was the general, and Shangshu Li Qing was the counselor of military affairs, leading 100,000 infantry and 20,000 cavalry out of Guangxi to attack Zhennanguan, Qianguo Gong Mu Sheng, Xu Heng, and Tan Zhong went out of Yunnan to attack Lihua Pass, and Zhenyuan Marquis Gu Xingzu sent 50,000 cavalry out of Guangxi to aid Po Lei Pass. Liu Sheng was a famous general at that time, he participated in Zhang Fu's southern expedition, and also made meritorious contributions with Zhu Di's northern expedition, and pacified the Tang Sai'er rebellion. In June, there was news that Li Li surrounded Changjiang very urgently (in fact, Li Li had been captured in April), Ming Xuanzong ordered Liu Sheng to go to the aid immediately, in September, Liu Sheng's army entered the pass to stay in the pass, and the Annan soldiers resisted along the way according to the dangerous columns, and the Ming army attacked bravely, even broke it, and arrived at Zhenyi Pass. Liu Sheng despised Li Li because of his repeated victories. Langzhong Shi An and the director Chen Yong told Shangshu Li Qing and said: "General Liu is arrogant, arrogant, and the soldiers are jealous. The thief may show weakness to tempt me, I don't know. To prevent thieves from setting up ambushes, the seal book is very serious, and the public should say it. Li Qingqi happened to be seriously ill at the time, so he barely supported himself to warn Liu Sheng, but Liu Sheng didn't listen. The main force of the Ming army advanced to the inverted horse slope, and Liu Sheng led more than 100 horsemen to cross the bridge first, but the bridge was suddenly damaged, and the rear army was not allowed to enter. Li Li ambushed the troops in all directions, the Ming army was defeated, Liu Sheng fell into the quagmire, and died in the dart. The next day, Liang Ming died of illness, and another day later, Li Qing also died of illness, and the Ming army was scattered and ownerless. At this time, Cui Ju led the army to Changjiang, Li Li besieged with a large army, the Ming army was attacked by the enemy before and after, and fought to the death. "The Ming army died or left, and none of them surrendered, and the 70,000 army was wiped out.
