Cao Cao was short of troops during the Battle of Guandu, why could he still kill Yuan Jun later?

Because Cao Cao did not use brute force, but came up with an ingenious way to fight against the enemy army, he was able to win more with less, and even if he lacked troops, he could still kill Yuan's army.

Because Yuan Shao's army didn't really want to fight Cao's army at that time, they just came to tell a lie, so Cao Cao was cornered, but his army still broke out with super combat effectiveness and defeated Yuan Shao's army.

Although the victory rate of the Battle of Guandu is low, the gap between the two sides may not be large. In order to highlight Cao Cao's wisdom and strength, the author deliberately wrote Cao Cao's troops to a lesser extent to highlight the degree of difficulty.

Because Cao Cao sent people to attack Wuchao at that time, and let people burn the granary of Yuan Shao's army, Yuan Shao's army was unstable and was counterattacked by Cao Cao.

Because although Cao Cao lacked troops, Cao Cao's combat command ability was very strong, and it was very easy to kill Yuan Jun.

Cao Cao had his own foresight, and he felt that after the battle of Zhendu, Yousui Guancha had to strive for strategic initiative, so he concentrated his troops, held the key passes, focused on fortification, and killed Yuan's army.

It's because he is a very suspicious person in the first place, and he is also afraid that the other party will snatch his place after winning, and he is also afraid that he will threaten his existence.

After Cao Cao won the battle of Guandu, the reason for killing Yuan's army was: Cao Cao led Zhang Jiaqin to let Liang and Guan Yu and others kill Yan Liang with the method of attacking the east and the west, and relieved the siege of Baima, and after that, the first ant designed to kill Wen Chou to defeat Yuan Shao's army, Cao Cao was at a disadvantage in the battle of Guandu, and Xu Xiao betrayed the intelligence to let Cao Cao win; Cao Cao burned all the grain and grass of Yuan's army at that time, and he had little grain and grass left, and the war had just ended, of course, there was no surplus grain and grass to supply so many new soldiers, since he could not have so many troops, he could not leave these soldiers to the enemy, so he killed all these soldiers.

Because only in this way can you consolidate your rights, consolidate your position, improve your position, not be afraid of the other party, maintain your own national power, and make your army stronger.
