In the Battle of Chibi, due to the defeat of the Wei army led by Cao Cao, there was a situation in which the Three Kingdoms were established later. In this battle, Zhuge Liangqiao borrowed the East Wind to have a scene of burning the chain ship. Did Zhuge Liang really borrow the East Wind by chance? In fact, no, the answer lies in the location of Sangu Maolu.
In November 208, Cao Cao led an army of 500,000 Wei against Eastern Wu. Although Cao Jun had half a million men and horses, it claimed 800,000 to the outside world. On the other side, sun Quan, who was weak, under the persuasion of Zhuge Liang, finally chose to join forces with Liu Bei to resist the enemy. Even if Sun Quan and Liu Bei joined forces against Cao Cao's army, Sun Liu's combined forces would only have 50,000 troops. They can only rely on the natural dangers of the Yangtze River to refuse to stay on the south bank of the Great River.
Subsequently, the combined forces of Sun Quan and Liu Bei encountered the vanguard of Cao Cao's Wei army at Chibi. Most of the Wei army were northern soldiers and were not familiar with water warfare, and at the same time, many people in the Wei army who came to the south were suffering from diseases. As a result, the morale of the Wei army was very low. As soon as the two armies fought, the Wei army suffered a small defeat. In desperation, Cao Cao could only lead the Wei army back to the north bank of the Yangtze River and garrison the Area of Wulin. As a result, the two armies formed a situation of confrontation across the river.
In order to alleviate the turbulence caused by the wind and waves on the ships, Cao Cao adopted Pang Tong's strategy and connected the warships with iron cables and wooden planks. Cao Cao believed that a series of warships was the best way to cross the river. But the target of the serial warship is too large to move freely. Later, some people reminded Cao Cao to beware of the fact that the coalition forces would attack with fire. Cao Cao believed that if Sun Liu's coalition wanted to attack with fire, it must rely on the power of the East Wind. It was the middle of winter, and the wind was northwest, so how could there be a southeast wind?
Cao Cao's use of Pang Tong's serial warship strategy can be said to be the underbelly of Zhuge Liang Zhou Yu. But at this time, Zhou Yu also saw an unfavorable side to the coalition forces, how to attack with fire without the East Wind? At the right time, Zhuge Liang said to Zhou Yu: If you want to break the Cao Thief, you need to attack with fire, everything is ready, and you only owe the East Wind. Subsequently, there was a scene in which Zhuge Liang mao introduced himself and opened the altar for Sun Liu to borrow the East Wind.
Zhou Yu took advantage of Huang Gaiqiao's trick of surrender, and relied on Zhuge Liang's borrowed East Wind to burn the Wei army's serial warships. In the end, Sun Liu's combined forces won the Battle of Chibi with a weak victory over the strong. Since then, the world has formed a situation in which the three kingdoms have stood. Is Zhuge Liang really the East Wind borrowed by chance? As Liu Bei's military master, Zhuge Liang can be described as an omnipotent in astronomical geography. However, the real reason why Zhuge Liang borrowed the East Wind was related to the location of Liu Beisan Gu Maolu. In the first sentence of the opening chapter of Zhuge Liang's "Table of Renunciation", it is written: "The subject is clothed, and he cultivates in Nanyang."
That is to say, Zhuge Liang's hometown is in Nanyang, and Chibi is not far from Nanyang. Chibi is adjacent to his hometown, and Zhuge Liang will inevitably be aware of the weather changes around Chibi. In November, the seasons are part of the winter solstice. On the day of the winter solstice, the river surface, which was originally dominated by the northwest wind, will inevitably blow a southeast wind. Zhuge Liang took advantage of the weather changes in the Chibi area to help Sun Liu's combined forces defeat the powerful Wei army.
