As the commander-in-chief of Hanzhong, Wei Yan held military power, so why couldn't he mobilize even five thousand troops?

First of all, Wei Yan was the captain of Hanzhong, and he had military power in his hands, and the force was quite large. The reason why he couldn't even defeat five thousand soldiers and horses was because Wei Yan lost the captain of Hanzhong. Although he was promoted, the military power he held was actually transferred and he later became Zhuge Liang's subordinate. The use of troops required Zhuge Liang's consent.

During the Three Kingdoms period, Shu Han had only one state, so Liu Bei divided Shu Han into four regions. In these four regions, he set up the Hanzhong Captain, the Jiangzhou Captain, the Yong'an Captain and the Lajiang Captain. The Hanzhong area is very important to the Shu Han. Liu Bei ordered Wei Yan to guard the Hanzhong area. At that time, Wei Yan could mobilize more than 20,000 troops. Later, Wei Yan could not even move 5,000 troops. When Zhuge Liang was in the Northern Expedition to the Central Plains, Zhuge Liang was stationed in Hanzhong and promoted Wei Yan, the captain of Hanzhong, ostensibly to Wei Yan. The promotion actually transferred Wei Yan's troops to Zhuge Liang.

Zhuge Liang just established the Prime Minister's Office and needed to recruit talents. Wei Yan was promoted to Prime Minister Sima. In addition, Wei Yan's rival Yang Yi also held this position. Prime Minister Sima's main job was to help the Prime Minister deal with the situation. Regarding war-related matters, although Wei Yan seems to have been promoted, the Prime Minister directly leads Prime Minister Sima in the Prime Minister's Mansion, which means that Zhuge Liang directly leads Wei Yan, so Wei Yan needs Zhuge Liang's consent when using troops.

Compared to the past, Wei Yan was the captain of Hanzhong and held a quarter of the country's troops. Although his official position was not as high as Zhuge Liang's, the two were not involved in the workplace, and Zhuge Liang did not directly lead Wei Yan. power, but after Wei Yan became Prime Minister Sima, he had to obey Zhuge Liang's orders. After Zhuge Liang transferred Wei Yan's military power, he promoted Wei Yan to the governor of Liangzhou, which was a kind of compensation for Wei Yan. However, Liangzhou was in the hands of Cao Wei at that time. If Liangzhou The state belongs to Shu Han, so Wei Yan, the governor of Liangzhou, is a real position, but this is not the case. The official position of Wei Yan is just a name and has no real use.
