What are the five major reasons why Cao Cao was always short of food in the Battle of Guandu?

The five reasons for the lack of food in the battle of Cao Caoguandu are as follows: first, the basic plate is too small, and there is only one place, Yanzhou; second, there are many local officials who violate the yang and yin; third, Liu Bei frequently attacked and harassed the rear; Fourth, Cao Cao had just finished attacking Xuzhou before; Fifth, it consumes a lot during transportation.

Because Cao Cao was attacked internally and externally, he was isolated and helpless. There was Liu Bei harassing in the rear, Yuan Shao vacillating in the front, and traitors inside. As a result, Cao Cao was always short of food in the Battle of Guandu.

Due to the lack of food, Cao Cao already had the idea of evacuating Guandu and returning to Xudu. Linked to Cao Cao's promise to his subordinates in charge of grain and grass transportation to defeat Yuan Shao within 15 days and Xu You's statement that there was only one month's grain, it can be shown that Cao Cao's grain in Guandu was only about 20 days' consumption.

The reason for this situation was not that Cao Cao's grain storage in Xudu was not enough to eat, but that his transportation line had been attacked and intercepted by Yuan Shao's troops, which destroyed a lot of the grain he transported from the rear, which led to a serious shortage of grain on the Guandu line.

1. When Yuan Shao and Cao Cao were holding each other on a white horse, Yuan Shao ordered to build an arrow tower and shoot arrows at Cao Cao's camp for several days, which shook Cao Cao's army. Subsequently, Liu Ye offered a thunderbolt plan to break Yuan Shao's crossbowmen, so that Cao Cao could get a place to be defended by ants in Guandu.

2. Cao Cao held on to Yuan Shao in Liyang, and wanted to return the army and then make plans, but Xun Yu offered a plan: "Today's soldiers are few and invincible, and it is okay to divide their stuffy service." When the public arrives in Yanjin, if the crossing troops are sent to the latter, Shao Bixi responds, and then the light troops attack the white horse to cover its unpreparedness, and Yan Liang can be a fowl."

So the Yuan army was broken.

3. Since August of the fifth year of Jian'an, the two armies have once again held each other in Guandu, and the two sides have won and lost each other. Later, Cao Cao's army was short of food, and it happened that Yuan Shao's strategist Xu Yu was at odds with the soldiers in the battalion and defected to Cao Cao. Xu Yu offered a plan to burn Yuan Shao's army rations, so that Yuan Shao was defeated without a fight.

Surprise attack on the nest, the more the number of troops, the higher the dependence on food and grass.

In 199 AD, Yuan Shao selected 100,000 elite soldiers and attempted to attack Xudu in the south, which opened the prelude to the Battle of Guandu. In 200 AD, Cao Cao launched an attack, defeated Yuan's army, and successfully retreated to Guandu; At that time, Cao Cao's soldiers were short of food and the soldiers were tired, so Cao Cao listened to Xu Youqi's attack on Wuchao and defeated the main force of Yuan's army.

In the Battle of Guandu, was Cao Cao's victory inevitable? Actually, it has something to do with them.
