Talk about the military and military strength of Liu Zhang, Liu Biao and Zhang Lu respectively.

First, Zhang Lu is definitely impossible. At that time, Liu Zhang was occupied by six counties in Yizhou, with a population of more than one million (the specific figures are different, but I personally think it is not less than two million). Jingzhou has six or seven counties (Nanyang, Nanjun, Jiangxia, Changsha, Wuling, Lingling and Guiyang), and its population is equivalent to Yizhou. Hanzhong is not as big as Yizhou, but in the mountainous area.

Second, because the populations of Jing and Yi are almost the same, even if there are differences, the war potential will not be too different. Liu Zhang, on the other hand, was indecisive, as can be seen from the fact that Yizhou soldiers in Liu Zhang, who had an advantage in the war with Zhang Lu, even lost. Liu Biao is resolute. If the two sides have equal military strength, the Sichuan army will undoubtedly lose.

Third, according to the Romance of the Three Kingdoms, Liu Biao's army has about 300,000 to 400,000 troops. However, I think that according to the principle of "one-fifteenth" in the Han Dynasty, there should be about 100,000 Liu Biao troops. As for Yizhou, according to historical records, the Shu-Han army barely had 200,000 troops at the peak of Zhuge Liang's period, so the number of Sichuan troops will not be much more than that of Jing troops, and it is estimated to be 1.5 to 200,000.

Fourth, Liu Biaojun has trained a group of veterans who dare to fight hard for many years, such as Huang Jin, Zhang Ji, Sun Jian, Sun Ce, Cao Cao, etc. However, Liu Biaojun has not fought for many years, and his military equipment is abandoned. Therefore, Liu Biaojun is more effective.

However, I think it still depends on whether it is a water war or a land war. Liu Biao's army is good at fighting on water, but it may not be able to gain the upper hand on land. Jing generals are mostly good at water warfare (Cai Mao, Zhang Yun and Huang Zu), while Sichuan generals are mostly good at land warfare (Yan Yan, Li Yan, Lengbao, Wu Yi and Zhang Ren ...).
