The answer is no, why? Pang Tong during the Battle of Chibi was a small role under Zhou Yu, who had never met Cao Cao and could not have been taken in by Cao Cao.
And the strength of the various military groups in history is objective, not a certain figure can easily change, in the Battle of Chibi in the interpretation of the Battle of Chibi Cao had a million troops, is an exaggeration, compared with the later battle of our army's millions of male divisions across the river, from the mouth of the lake in the west to Jiangyin more than 500 kilometers from the west and the middle section of the attack, is a real million troops, and Cao Cao and Zhou Yu confronted in such a small place as Chibi, both sides can drive sailing ships to spy on each other's military intelligence overnight, the visible distance is very short, A single fire can burn the entire camp, which shows that the scale is very small.
Therefore, during the Battle of Chibi, Cao Cao's real front-line combat strength was very small, Cao Cao and Zhou Yu Liu Bei's troop strength was not much different, up to tens of thousands of people, Cao Cao because the soldiers were infected with the plague, the combat effectiveness was very poor, and it was not conducive to retreating to the north. Even if Cao Cao was able to defeat Zhou Yu at Chibi, he could not eliminate Liu Bei and Sun Quan, at that time Liu Bei had been defeated many times without dying, and Sun Quan had already laid a foundation in Jiangdong, it was impossible for Cao Cao to pacify Sun Liu in one fell swoop, compared to Cao Cao after the Battle of Guandu, it took Cao Cao eight years to pacify the north, Cao Cao realized that Jiangnan could not be quickly pacified, and only then returned to the north to make long-term plans.
Therefore, the trend of Cao Sun Liu later was objective, and it was impossible to pacify Sun Liu in one fell swoop because of the coming and going of a certain person, compared with Cao Cao who took eight years to pacify the north after the Battle of Guandu, Cao Cao realized that Jiangnan could not be quickly pacified, and only then returned to the north to make long-term plans. Therefore, the trend of Cao Sun Liu later is objective and will not change because of the coming and going of a certain person.
