However, Yang Jian did not immediately attack the state of Chen, the state of Chen in 584 was not completely defeated by Chen Shubao, and there was the Yangtze River, so Yang Jian continued to implement the system of equal land and the system of rent and forced labor, established the system of three provinces and six ministries in the central government, implemented the state and county system in the localities, and reformed the military system of the government, so as to facilitate the development of social economy, strengthen the centralization of power, and improve the combat effectiveness of the army.

In 585 (the fifth year of Emperor Kaihuang of Sui, the third year of Southern Chen Zhide, and the twenty-fourth year of Tianbao of Western Liang), Yang Jian took Yang Su, the Duke of Qinghe, as the governor of Qizhou, and passed through the upper reaches of the Yangtze River. At the same time, within three years, hundreds of thousands of people were mobilized to repair the Great Wall in the areas of Shuofang (Zhiyanlu, now Baichengzi, south of Wushen Banner, Inner Mongolia) and Lingwu (Zhihuile, southwest of Lingwu, Ningxia), and built dozens of cities on the eastern edge of Shuofang, so as to strengthen the northern border defense and ensure that the rear would not have to worry about the south.

In the seventh year of the emperor's reign (587), Xiao Cong, the queen of the Western Liang, was abolished, occupied Jiangling, and the Western Liang died. The forces of the Sui State have crossed the Yangtze River and forced to the door of the Chen State, at this time, Nan Chen was almost defeated by Chen Shubao, and the forces of the Sui State have arrived at the doorstep, and they have not attracted enough attention from the court.

In March of the eighth year of the emperor's reign (588), Yang Jian issued an edict, listing Chen Shubao's crimes and sending a seal letter to abuse his crimes 20 times, and distributed 300,000 copies of the edict in Jiangnan to win the hearts of the people. In October of the same year, Huainan Province was set up in Shouchun, with Yang Guang, the king of Jin, as the Shangshu order, to coordinate all the troops and horses, and Gao Xi as the marshal Changshi to decide the marching strategy, and led 80 governors and 518,000 soldiers to the south.

In addition to frontal combat, before marching, Chen envoys were detained, contacts were cut off in order to keep military secrets, and a large number of spies were sent to infiltrate Chen to carry out sabotage and disruptive activities.

For the celebration of the Yuanhui (i.e., the Spring Festival), he ordered the two sons of Jiangzhou (now Jiujiang, Jiangxi) and Xuzhou (now Zhenjiang, Jiangsu) to lead warships back to Jiankang, which made the defense of the river even weaker.

In December, the Sui army in the upper reaches of the Yangtze River launched the first attack.

I don't know if you still remember, as mentioned earlier, when the north attacked the south, because they were not accustomed to water warfare and the humidity and heat of the summer in the south, they mostly crossed the Yangtze River to attack the south during the dry period of the Yangtze River in winter and when the south was relatively cold; On the contrary, when the south attacked the north, because of the habit of water warfare, not the cold of the winter in the north, taking advantage of the summer when the Yangtze River rose and the north was warm, the Sui army attacked by boat from the waterway into the north.

After a month of hard fighting, he broke through Chen's army in the first month of the following year (589) and occupied the mouth of Xiling Gorge.

Chen Huiji, the assassin of Chen Jingzhou, was stationed in the public security (now northwest of Hubei Gong'an), and when he saw that the general trend had gone, he led an army of 30,000 and more than 1,000 ships to the east of the river, trying to enter the aid of Jiankang, but he and Zhou Luohu were blocked by Yang Junjun to the west of Hankou, and the Chen army was finally unable to rescue Jiankang. Yang Su of the Sui army continued to march east along the Yangtze River with the main force, joined forces with Yang Junjun in Hankou, and sent Liu Renen's troops south to Xiangzhou (now Changsha, Hunan) to capture Chen Shushen, the king of Chen Yueyang, so that the middle reaches of the Yangtze River were no longer owned by Chen.

The situation is already so critical, but above the court of the Chen Dynasty, there are still traitors who can't figure it out!

When the news of the Sui army's occupation of the upper reaches of the Yangtze River reached Jiankang, they were all withheld by Shi Wenqing and Shen Keqing, who were in charge of secrets in the imperial court, making Jiankang City defenseless. When the Sui army advanced to the north bank of the Yangtze River, Shi Wenqing refused to send troops to strengthen Jingkou (now Zhenjiang, Jiangsu), Quarry (southwest of present-day Ma'anshan City, Anhui), and other places.

Aren't these two really spies sent by Yang Jian? No, they're not, it's a tease sent by the monkey, I really want to know what these two people think, could it be that they want to defect to the Sui State with this, alas, I don't understand it at all.

On the first day of the first month of the first month of 589, the Sui army in the lower reaches of the Yangtze River crossed the river by way on the occasion of Chen Huan's Yuan meeting. He Ruobi's army crossed out of Guangling to the south, Han captured the tiger army out of the Lujiang River and crossed the night from the mouth of the Hengjiang River (now southeast of Hexian County, Anhui), attacked and occupied Caishi (now southwest of Ma'anshan City, Anhui), and Yang Guangjun, the king of Jin, went out of Liuhe (now Jiangsu) and entered Taoye Mountain (now southeast of Liuhe).

On the fourth day of the first month, Chen Baobao finally realized that the situation was unfavorable and issued an edict to the commander Chen Jun to reject the enemy.

However, Chen Guo was almost defeated at the hands of Chen Shubao, although the generals and soldiers should send troops to fight, but the morale was insufficient, the Sui army was advancing like a bamboo, and the Chen army was repeatedly defeated.

The Sui army sent a section to block the northern reinforcement of the Chen army in the Sanwu area (east and south of present-day Taihu Lake in Jiangsu and Shaoxing, Zhejiang) in Qu'a (present-day Danyang, Jiangsu), and the main force successively occupied Guyu (present-day Dangtu, Anhui) and Shicheng (in Qingliangshan, west of present-day Nanjing).

In order to cooperate with the main force's operation, the Sui general Wang Shiji's army also successfully captured Qikou (now southwest of Qichun) from Qichun, defeated Chen General Jichu, and approached Poyang Lake in Jiangxi; The Yanrong Naval Division also moved south from the Shandong coast and occupied the Sanwu area.

Jiankang (now Nanjing) as the capital, must have it as the capital of the confidence, the terrain is easy to defend and difficult to attack, at that time Jiankang still has 100,000 troops, however, Chen Shubao has no master, will hand over the government to Shi Wenqing, Shi Wenqing in front of Chen Shubao slandered the generals, saying that they are afraid of high merit and weak rewards, sometimes complaining, can not be entrusted with important tasks, so all the generals have suggestions, are blocked. Chen Shubao himself did not take the advice of the generals, gave up Zhongshan, Shishi and other dangerous places, and stuck the main force inside and outside Jiankang City, and let the Sui army surround Jiankang City in vain.

The Sui army attacked Jiankang, but Chen Shubao put on the wrong formation, and the north and south were more than 20 miles long, and they couldn't take care of each other. The generals also did not fight or surrendered for various reasons. The surrendering general Ren Zhong led the Sui general Han Baohu straight to the Zhuque Gate, and under Ren Zhong's persuasion, the soldiers who were already unstable and had no morale dispersed in a hurry, and Han Baohu attacked the city.

The civil and military officials in the city all fled, the court was empty, and only the servant Yuan Xian and the Houge Sheren Xiahou Gongyun did not leave. Chen Shubao also planned to escape, but Yuan Xian persuaded him to follow the precedent of Emperor Wu of Liang when he saw Hou Jing and surrender to the Sui Dynasty army with dignity, but Chen Shubao did not listen, and jumped into the dry well with his concubines Zhang Lihua and Kong Guiren to hide, Yuan Xian and Xiahou Gongyun had no choice but to surrender to the Sui army.

Chen Shubao was also found by the Sui army from the dry well, and was escorted to Han to capture the tiger's tent in embarrassment, Zhang Lihua and Shi Wenqing, Shen Keqing, Yang Huilang, Ji Huijing and others were beheaded in the city, Chen perished, passed on the five emperors, a total of 32 years.

When I saw Chen Shubao, I remembered Xiao Baojuan, the Eastern Dusk Marquis of Southern Qi, the two of them were the same faint, but Chen Shubao was more comfortable than Xiao Bao, the royal family and courtiers of the Chen Dynasty were almost all taken to the Sui State, Chen Shubao was very courteous in the Sui State, without the trouble of state affairs, Chen Shubao was relieved to indulge in wine, drunk and dreamed of death, Sui Dynasty Renshou four years (604), Chen Shubao died of illness in Luoyang, at the age of fifty-two.
