Why can't the 300,000 Taiping Army resist the attack of 1 Wanxiang Army?

In the Battle of Tianjing, A Xiang's army of more than 10,000 people in Ceng Guoquan went deep alone and went straight to Tianjing, the capital of Taiping Heavenly Kingdom. Hundreds of thousands of Taiping rebels can't help this Xiang army. Finally, this small Xiang army not only gained a firm foothold, but also broke the city in one fell swoop, proclaiming the demise of the Taiping Heavenly Kingdom!

At the end of 1863, Tianjing was besieged. Hong Xiuquan ordered Taiping rebels fighting in other places to return to the capital. At that time, hundreds of thousands of soldiers and horses gathered in Tianjing, and their opponents were more than 10,000 A Xiang troops. Why did the Taiping Army lose despite its huge military superiority?

The Northern Expeditionary Army took away 20,000 elite soldiers, only to be wiped out by the Qing army north of the Yellow River. Shi Dakai has taken away 654.38 million troops, many of which are elite troops. As a result, Taiping veterans lost at least half. The quality of the recruits is very poor, and they are basically citizens or farmers who have been forcibly recruited into the Taiping Army.

1862 In September, Li Xiucheng came to the rescue with more than 13 Wang (the royal titles in the late Taiping Heavenly Kingdom were really worthless) and 100 troops. At first, Li Xiucheng was really fierce, and he couldn't break through, so he was responsible for clearing the field. The Taiping Army killed him several times, but there was no breakthrough.

Although the Taiping Heavenly Kingdom is outnumbered, the army is a rabble. Soldiers of the Taiping Heavenly Kingdom were originally assembled by farmers in a hurry. Although the quality of soldiers has been improved in the long-term battle, with the relaxation of discipline in the later period, the combat quality of soldiers has gone from bad to worse.

In the later period of the Taiping Heavenly Kingdom, Hong Xiuquan claimed a large number of titles, and the Taiping Army desperately recruited soldiers, but did not train elite soldiers. As a result, many soldiers of Taiping Army just make a living, and they have no fighting capacity and accomplishment at all. The apparent strength and the number of people on the books are just a mob.

Hong Xiuquan was the spiritual power at the end of the Taiping Heavenly Kingdom. Hong Xiuquan told the soldiers of the Taiping Heavenly Kingdom not to worry, and God would come to save them. This statement was made by Hong Xiuquan, leader of the Taiping Heavenly Kingdom, and everyone believed it. However, Hong Xiuquan himself fell ill and died. The last spiritual pillar of the Taiping Heavenly Kingdom soldiers collapsed, and their failure was inevitable.
