In 220, Cao Pi was proclaimed emperor, and the world was divided into three. During this period, except for the brief unification of the Western Jin Dynasty, Chinese history fell into a history of more than 300 years of melee, and the Central Plains was full of wolf smoke.
In the 369-year history of the Wei and Jin dynasties, Liu Yu had the hope of unifying the world. However, his younger brother Liu Daogui died of illness, taking away the opportunity for the Southern Song Dynasty to unify the world. Liu Daogui lives for 10 more years, and there will be a unified "Song Dynasty" in history, and the achievements will not lose to the Qin and Han dynasties, and there will be no Sui and Tang dynasties in history.
Judging from Liu Daogui's ability and the situation after Liu Daogui's death, the probability of rewriting history by giving Liu Daogui 10 more years is very high.
1. Liu Daogui has strong comprehensive ability and can play a role in replacing Liu Yu and taking charge of the Beifu Department
Back then, Liu Yu, who was known as the "Imperial Harvester", was super strong in military ability. In the opinion of historian Lu Simian, Li Shimin is just an ordinary emperor, and he is far from Liu Yu.
Liu Yu's military ability is at the ceiling level, but his political ability, especially in terms of employing people, is insufficient. Liu Daogui is a comprehensive talent, although he is not the strongest and the top in every side, but he has developed in an all-round way.
In December 403, Huan Xuan usurped the throne and became emperor and established "Huan Chu". At the beginning of the following year, Liu Yu secretly contacted the generals of the Beifu Department in Jingkou, preparing to attack the Jingshi by force and eliminate Huan Xuan.
Liu Yu's plan was to revolt in Jingkou, Guangling, Jiankang, and Liyang at the same time, and attack Huan Xuan on three sides. As a result, both Jiankang and Liyang failed, and only Liu Daogui won the raid on Qingzhou in Guangling, where he eliminated the Huan clan's forces, and then crossed the river to join Liu Yu.
Liu Daogui raided Huan Hong, acted quickly, did not drag mud and water, and his courage, courage, and ability were similar to his brother Liu Yu.
The brothers fought together, and Liu Daogui took the lead, defeating Huan Xuan's 40,000 soldiers and horses in the Battle of Zhoushan, and immediately attacked the Beijing Division. At this time, it was only 3 months before Huan Xuan became emperor, and Huan Xuan fled from Jiankang.
Liu Daogui took advantage of the victory to pursue, defeated the "Chu army" again in Sangluozhou, conquered Xunyang, and took Jiangzhou. Huan Xuan fled to Jingzhou to take refuge, Liu Daogui, Liu Yi, and He Wuji traced the river and eliminated 20,000 "Chu troops" in Ezhou, Huan Xuan fled to Sichuan and was executed by his generals.
Huan Xuan was called the emperor, and in less than half a year, he was planted in the hands of the Liu brothers. Liu Daogui made outstanding contributions, but in order to avoid the intensification of internal contradictions in the Beifu system, he gave the credit to Liu Yi and He Wuji.
After the demise of "Huan Chu", Liu Daogui served as the assassin of Jingzhou, exterminated the remnants of the Huan clan, and developed production, Jingzhou's economy recovered, and the people's hearts were stable. In addition, he united the generals of Beifu and reused generals such as Wang Zhenzhi, Tan Daoji, and Zhiyanzhi, which were supported by the soldiers.
Lu Zongzhi, who guarded Xiangyang, and Liu Daogui also tried their best to improve relations and stabilize the situation upstream. Later, in the troubled times of Lu Xun and Xu Daofu, Liu Daogui and Lu Zongzhi fought side by side, formed a deep friendship, and successfully quelled the rebellion.
In 409, Liu Yu went on an expedition to the north of Southern Yan and fought with the Xianbei cavalry in the Central Plains and destroyed the country. Lu Xun and Xu Daofu took advantage of Liu Yu to lead his troops out, rebelled in Lingnan, captured Jiangzhou, eliminated He Wuji, and annihilated Liu Yi's 30,000 army, and Liu Yi was only spared.
Lu Xun and Xu Daofu were in turmoil, Liu Yu suffered from the enemy on his back, and the situation downstream was a mess. If Lu Xun adopted Xu Daofu's suggestion and directly attacked the Jingshi, the victory or defeat would be unpredictable, and it would be difficult for Liu Yu to counterattack.
Lu Xun and Xu Dao divided their troops and postponed the attack on Beijing. Liu Yu left the infantry behind, personally led thousands of cavalry south, quickly entered the Beijing division, deployed defensive matters, and fought the rebels.
At this time, Later Qin Yao Xing sent Gou Lin to lead 20,000 cavalry south to attack Jingzhou with Qian Shu and Huan Qian. Liu Daogui was attacked on three sides, and the people in Jingzhou were panicked, and many people had plans to surrender, but Liu Yu had no way to support him.
Everything has to rely on yourself, Liu Daogui's performance is much stronger than Liu Yi and He Wuji. Liu Daogui took advantage of his position on the inside line to quickly fight against the soldiers and horses of Qian Shu and Huan Qian and defeat them.
Huan Qian's army was defeated and defected to Gou Lin, and the Qin army was wiped out by Liu Daogui before it could complete its defense. Then, Liu Daogui gathered the main force and launched a decisive battle with Xu Daofu's 30,000 army, fought for several days, and then eliminated it, laying the foundation for the victory of the counterinsurgency.
In the rebellion of Lu Xu, Liu Daogui's performance was too eye-catching, and he was second only to Liu Yu. Faced by enemies on three sides, and without any support, he was able to break them all, Liu Daogui deserved to be a famous general.
It's a pity that Liu Daogui died young, and the time was fixed in 412, and he was only 43 years old. The political and military impact of Liu Daogui's death was related to the question of whether the Southern Dynasties could unify the world.
Second, Liu Daogui died of illness, Jingzhou was chaotic, Liu Yu missed too much time, and available people
After the end of the rebellion of Lu Xun and Xu Daofu, Liu Yu did not use troops abroad for nearly 7 years. At this time, Liu Yu's prestige was soaring, and the Northern Dynasty had no opponents.
Later Qin Emperor Yao Xing, just in general, didn't dare to make a move with Liu Yu, and even Helian Bobo couldn't handle it. As for the "Zhuliang" in the Longxi area, it is just a small fight, and it is not an opponent.
The Northern Wei Dynasty was a powerful country, and the combat effectiveness of the Xianbei Iron Cavalry could not be ignored. However, Emperor Daowu Tuoba was executed by his son in 409, and Emperor Ming Yuan was of medium ability and was no match for Liu Yu.
Later, Liu Yu attacked Yao Qin in the north, and defeated 40,000 Xianbei cavalry with 3,000 soldiers and horses, which is enough to show that no one in the Northern Wei Dynasty was Liu Yu's opponent.
Tuoba, known as Genghis Khan's "prototype", has nothing to say about the value of force. Tuoba Tao is also the leader of the young emperor. At this time, Tuoba Tao was killed, and Tuoba Tao had not grown up, which was a godsend for Liu Yu.
So, does Liu Daogui's death have anything to do with Liu Yu's inability to grasp "time"? The answer is yes. Liu Daogui is not dead, Liu Yi is not qualified to serve as the assassin of Jingzhou, and Liu Yu does not have to waste time to quell the rebellion.
Liu Daogui is alive, Liu Yi is nothing. Liu Yi is old, but the rebellion of Lu Xun and Xu Daofu has made him lose his direct troops, and his prestige has been discredited, how can he argue with the Liu brothers.
As for Sima Xiu's rebellion, it is not worth mentioning. Sima Xiuzhi's ability is average, but his ally Lu Zongzhi and his Xiangyang army are particularly capable of fighting, and they are the fierce opponents of the Beifu soldiers, which makes Liu Yu pay a great price.
The reason why Lu Zongzhi supported Sima Xiuzhi was because Liu Yu purged dissidents, and he was worried about being eliminated. Liu Daogui is alive, Lu Zongzhi has a sense of security, and he can become a force that Liu Yu can rely on, and Sima Xiuzhi can't make trouble.
Five years after Liu Daogui's death, Liu Yu was either on the conquest of Jingzhou, or on the way to conquer Jingzhou, busy with eliminating dissident forces. In this way, Liu Yu missed the best "window period" of the Northern Expedition, which affected the course of history in the future.
What does it mean to give Liu Daogui an extra 10 years? With Jingzhou in hand, Liu Yu eliminated the Shu ahead of schedule, and then sent troops to the Northern Expedition to the Central Plains to complete the task of the "Chan Dynasty" and establish the Song Dynasty while recovering the lost territory.
Liu Daogui is alive, and Liu Yu has something to rely on. According to historical development, after Liu Yu took Guanzhong and eliminated Yao Qin, it would be Liu Daogui who would guard Chang'an, and generals such as Wang Xiu, Wang Zhenxi, Shen Tianzi, and Fu Hongzhi would not fall into infighting.
In this way, Liu Yu can rest assured to return to Jiangnan, replace the Eastern Jin Dynasty, and establish the "Song Dynasty". Then, Liu Yu asked Liu Daogui to send troops to eliminate Helian Bobo, completely control Guanzhong, and appease the "Zhuliang" in Hexi to control the northwest.
After taking the northwest, Liu Yu and Liu Daogui sent troops to attack the Northern Wei Dynasty. At this time, even if Liu Yu could not completely annihilate the Xianbei cavalry, he could expel them from Hebei and return to the vicinity of Yanmen Pass. Next, Liu Yu united with the Rouran cavalry on the grassland to attack the Northern Wei Dynasty in the north and south, and Tuoba Xianbei had to flee back to the grassland all the way.
The Northern Wei Dynasty fled to the grassland and fought with Rouran for a long time, posing no threat to the Central Plains. At this time, Liu Yu could let the "Zhuliang" of Hexi enter Beijing and hand over the land, otherwise it would be eliminated by force.
After dealing with the "Zhuliang", let Wang Zhenevil, Zhu Chaoshi, Zhu Lingshi and other fierce men expedition to the Western Regions to reopen the Silk Road. In this way, Liu Yu basically restored the territory of the two Han Dynasty, and the "Song Dynasty" will be a strong era.
Liu Daogui's death changed all that. Liu Yu spent 5 years to rectify the interior, and then went north to Yao Qin, but Liu Muzhi died of illness, and he could only let Liu Yizhen sit in Chang'an, causing the generals of the Guanzhong and Beifu departments to fight each other, and Guanzhong gained and lost.
After losing Guanzhong, Liu Yu was busy claiming the title of emperor and had no time for the Northern Expedition. In 422, Liu Yu planned the Northern Expedition, but he ran out of time, and died before leaving the army, at the age of 60, and Liu Yifu succeeded him.
In 424, Xu Xianzhi and four other auxiliary ministers executed the young emperor Liu Yifu. During this period, the Northern Wei Dynasty went south, seized the four towns of Henan, and gained the initiative. After that, the Southern Song Dynasty was busy with infighting, and lost Huaibei and Shandong, and the territory was greatly reduced.
