Basically impossible. 1. Yue Fei was 32 years old when he opened the dental office, and he was the youngest. The base camp is in Ezhou, which is the middle road of the three-army battle in the Central Plains. If the Northern Expedition requires the cooperation of Han Shizhong, Yang Yizhong, Liu Qi, Zhang Jun, Zhang Jun, Wu Jie, Wu Lin and other military leaders, if only one so-called famous general can penetrate China, then he has read too many romance novels.
2. The organizational capacity of the Southern Song Dynasty court was unstable. The Northern Expedition required too many conscriptions and taxes, and the southern people and the landlord class generally resisted. In ancient China, there was no concept of country, only the concept of family. No matter who becomes the emperor, safeguarding the interests of the family comes first. The formation of the concept of nationality and ethnicity in modern times also relied on the Anti-Japanese War. During the Southern Song Dynasty, peasant uprisings broke out one after another. Among those Yue Fei killed were Yang Yaozhong and others. Among the Yue family troops there were also generals such as Yang Zaixing who had surrendered to the peasant army. The instability in the rear was obvious.
3. The Yue family army was mainly infantry. In the later period, Liu Yu captured about 20,000 horses, and the number of war horses should be around 5,000. However, the combat formation and training of cavalry requires a lot of military expenditure and time. Yue Fei stayed in Ezhou for five years to train the Beiwei and Youyi troops. According to the total number of 12 battalions of Yue Fei's army, there would be no more than 3,000 cavalry soldiers. If the Northern Expedition to Kaifeng was to be carried out, the heavy infantry in the Central Plains of Henan would not be able to compete with the cavalry. This is a military issue. Nearly 2,000 miles from Ezhou to Kaifeng, the Jin Army cavalry can give you a fatal blow at any time on the long logistics supply line. In ancient times, long-distance troop deployment was a very troublesome problem.
4. A comprehensive look at Yue Fei's record shows that it was mainly defensive operations, fighting against the peasant army, and fighting against traitor troops such as Liu Yu, Li Cheng, and Li Qiong. Internal operations and external operations with a range of 2,000 miles are completely different concepts. Fighting against the puppet troops and fighting against the Jin Army field corps are also completely different concepts. The most famous offensive operations of the Yuejia Army were in Shunchang and Yancheng. (Shunchang was mainly fought by Liu Qi, with Yue Fei as a reinforcement). They fought the traitor troops led by Han Chang and the remaining troops of the Jin Army (the second-class army). The Jin Army In fact, the Central Plains region was strategically looked down upon. No field troops (A-class troops) were deployed, and the traitor troops were mainly relied on to stay behind. It was even returned to the Southern Song Dynasty in the treaty. But the further north you go, the greater the pressure on the Yuejia Army and the more dangerous the logistics. This is obvious. If the Jin Army's field troops move south in a large scale, relying on the Yuejia Army's cavalry and dragoons (mounted infantry) is obviously not enough. Judging from the results of the battle, the most famous Battle of Yancheng (frontal tough battle), the battlefield was cleared and only "more than two hundred horses" were captured and "the chieftain was killed", which was a very vague victory. One reason is that the infantry could only defeat the cavalry. Cannot achieve annihilation war. There is another reason why the results are not very significant. (In the previous battles with the puppet army, they often "gained more than 2,000 horses, armor, and weapons, and surrendered more than 3,000 cavalry.")
5. The slogan of the Yue family army is to freeze to death without demolishing the house, and to starve. Do not take captives to the death, that is, you cannot feed the enemy. If it all depends on logistics, in Yue Fei's own words, "a day costs a thousand gold." In its heyday, the Yue Family Army had 12 battalions, 22 commanders, five commanders, 252 generals, and about 80,000 officers and soldiers. Among them, there should be more than 20,000 combat soldiers and veterans, and more than 50,000 elite peasant soldiers were recruited. There are 20,000 horses (including about 5,000 war horses). The Northern Expedition will require 400-500,000 logistics civilians and auxiliary troops to ensure food and grass. Even though Yue Fei had a battalion of naval forces, it was basically impossible to use water to transport food after passing the Lianghuai River. When Qin Hui's withdrawal order was issued, the Yue family army only reached De'an Mansion (Anlu, Hubei), followed by Li Ruoxu Fighting with Yue Fei's imperial edict. (It can be seen that this was also one of the reasons why Zhao Gou killed Yue Fei) Qin Hui had to ensure the logistical support of the long front from Xianren Guandong to Lianyungang in the west. It is understandable that he was too ambitious but insufficient.
