In the Battle of Yiling, when the Wu army faced Liu Bei's large-scale attack, Lu Xun adopted a strategy to avoid his sharp edge, choosing a temporary retreat, not having the ability to do it for a while, but patiently waiting for the best time. In the end, under Liu Bei's negligence, Lu Xun took advantage of the time and place to attack the Shu army by means of fire attack, and at the same time cut off the Shu army's retreat route in terms of waterways, and eventually the Shu army was in chaos and collapsed. At this time, Liu Beifang was in chaos, and he couldn't take care of his tens of thousands of soldiers at all, and he knew that his life would be difficult to protect if he didn't flee. Therefore, Liu Bei left tens of thousands of Shu generals and fled in the direction of the White Emperor's City under the escort of his own soldiers.
At this time, because Lu Xun was the first time to command the battle as a great general of Eastern Wu, and seized such a good opportunity, of course, he would not let Liu Bei go, so Lu Xun began to chase after Liu Bei, who fled. Just at this time, a white-robed veteran riding a Lu horse suddenly appeared behind Liu Bei, this person was Zhao Yun, and as soon as he saw him, Lu Xun gave up chasing Liu Bei.
In fact, Lu Xun saw Zhao Yun and ordered the withdrawal of troops, not only fearing Zhao Yun's prestige, but by two reasons, the first is that Zhao Yun had long expected that Liu Bei might fail, so he prepared in advance and brought a lot of reinforcements, plus some of the scattered troops that Liu Bei had gathered at that time, enough to have 20,000 soldiers and horses, the second reason was that Lu Xun cared about Wei Guo, because at this time, if Wei Guo took the opportunity to fish in muddy waters and attacked his rear, he would definitely suffer great losses, because in that era, It must be that no one believes anyone, and everyone will worry that the other side will reap the benefits of the fisherman, so they quickly stopped the pursuit and took the initiative to withdraw their troops.
Liu Bei was able to escape, not by Relying on Zhao Yun's guards to escape, but because his subordinates desperately protected him, so that Liu Bei could escape. When Liu Bei arrived at Yong'an, Xu Sheng and Pan Zhang of Eastern Wu all advocated expanding the results of the battle and taking advantage of the victory to pursue Liu Bei. However, at this time, Zhao Yun had already led his troops to arrive, plus the three armies of yiling and yong'an garrison, there were nearly 20,000 people, and Lu Xun's good opportunity to capture Yong'an had been lost, and he was worried that Cao Wei would sneak in from the rear. This was because most of the Eastern Wu army was west of Yiling, so Lu Xun had to take the initiative to withdraw. The Battle of Yiling at the time of the Three Kingdoms ended.
