If we boldly assume that Song Gaozong and Zhao Gou support Yue Fei's Northern Expedition, does Yue Fei want the Northern Expedition to succeed?
First of all, from a military point of view, Yue Fei's command ability is beyond doubt. In the ancient history of China, Yue Fei's command and combat capability should rank among the top three. A good horse with a good saddle and an excellent general must have a matching iron army. Coincidentally, Yue Jiajun personally brought out by Yue Fei is such a well-deserved iron army. Yue Jiajun will attack the battle and gradually develop from the initial 2000 people. To become a powerful amphibious force, especially Yue Fei, there is an armored force under his command. This cavalry unit of 8,000 people is the essence of the Han cavalry at this time, and it is a powerful army that is not afraid of hand-to-hand combat with any opponent. Under the guidance of Yue Fei's two lovers, Yue Yun and Zhang Xian, it is the sharpest spear of Yue Jiajun and dares to pierce all the armor of the enemy standing in front of him. Yue Jiajun's strong fighting capacity is the source of Yue Fei's confidence. With such a powerful army as an armband, Yue Fei's strong command ability can be added points.
It can be said that as long as the court supports Yue Fei, militarily, Yue Fei has nothing to say. After all, there is a slogan circulating among the enemy that it is easier to shake the mountain than the Yuegujun, which shows the enemy's fear of Yuegujun's powerful fighting capacity.
The success or failure of the Northern Expedition depends on the economy when the fighting capacity is secure. The economy of the Song Dynasty has always been their strong point, but it also depends on the time. In the early days of the establishment of the Southern Song Dynasty, the imperial court had a hard time, and the finances of the Song Dynasty were basically idle. At this time, the Song Dynasty's finance faced two major troubles. On the one hand, the constant invasion and harassment by the Japanese pirates disrupted the original water towns in the south of the Yangtze River, making it impossible for key fiscal and taxation areas to collect taxes. This has seriously affected the country's financial resources. In addition, due to years of fighting, it is necessary to maintain a huge army, and the army is precisely the biggest gold swallowing beast. Without financial support, these soldiers are unwilling to fight for their country, which is also the biggest difficulty that Zhao Gou has encountered. However, if Zhao Gou is willing to help Yue Fei wholeheartedly, this difficulty cannot overwhelm the Southern Song Dynasty court, because Yue Fei has also made his own efforts on this issue. After laying the foundation of Xiangyang area, Yue Fei established a base there slowly and steadily, and tried his best to restore local production. With the tax paid by the local government in one year, Yue Jiajun was able to support the Northern Expedition for three months, greatly alleviating the financial difficulties of the imperial court. So as long as the imperial court has the determination to support the Northern Expedition, this difficulty is definitely not a problem.
Moreover, Yue Fei has sent people to contact many insurgents in Heshuo area. The insurgents there all obey Yue Fei's command and are willing to cooperate with Yue Fei. As long as Yue Jiajun gets his hands on Henan and Hebei, these insurgents will definitely bring great trouble to the local enemies and reduce the positive resistance of Yue Jiajun. Moreover, the Southern Song Dynasty imperial court mastered more than Yue Jiajun. At this moment, we can send Wu brothers and sisters to Sichuan to attack Shaanxi from Sichuan. Competing with the enemy for Shaanxi's territory and reducing Yue Fei's pressure will make the Northern Expedition with Yue Fei as the main force achieve the greatest success, so I think that as long as the Southern Song Dynasty imperial court gives strength, Yue Fei's Northern Expedition will succeed in all likelihood.
