Zhuge Liang successively attacked Wei specific several times

6 times each introduction.

For the first time, Zhuge Liang defeated Xiahou Nan, the concubine of Wei, captured the three counties of Tianshui, Nan'an, and Anding, and defeated Cao Zhen, the governor of the Wei army; Later, due to Ma Tan's defeat in the street pavilion, he was forced to return to Hanzhong, and the three counties were regained.

The second time, Zhuge Liang's troops went out of Chencang and were restrained by the Wei general Hao Zhao; Wei sent Yong to Wang Shuang's aid to Chen Cang, Zhuge Liang left Wei Yan to reject Wang Shuang, and led a large army to attack Qishan, defeating Cao Zhen in a row; Later, due to the exhaustion of food, he retired from the army, and planned to behead Wang Shuang. The third time, Zhuge Liang attacked Chencang, and then went to Qishan, and ordered King Jiang Wei to divide Wudu and Yinping equally; Wei took Sima Yi as the governor and led the army to resist; Zhuge Liang defeated Sima Yi in a row, but quietly withdrew due to illness.

sp;On the fourth time, Wei took Cao Zhen and Sima Yi as the chief and deputy governors to attack Hanzhong, but retreated due to heavy rain for several days; Zhuge Liang divided his troops into two ways, angry Cao Zhen, and defeated Sima Yi; Sima Yi couldn't hold out, so that Shu general Gou An returned to Chengdu to spread rumors, accusing Zhuge Liang of wanting to usurp the throne, and Zhuge Liang was forced to retreat. For the fifth time, Zhuge Liang returned to Qishan and defeated Sima Yi in a row; Due to the lack of food and grass, Du Hu Li Yan lied that Wu wanted to attack Shu and complained to Zhuge Liang in an emergency; Zhuge Liang hurriedly withdrew his troops and shot Zhang He, the general of Wei, in the retreat.

The sixth time, Zhuge Liang divided his troops into five routes, and then went out of Qishan, taking the opportunity of Wei's Zheng Wen to surrender, and defeated the Wei army; and burned the valley above and seized Weinan; Sima Yi couldn't hold out, Zhuge Liang was stationed in Wuzhangyuan, and soon fell ill.

Zhuge Liang made a total of six northern expeditions to Cao Wei, known as the six out of Qishan in history.

1. As soon as he came out of Qishan, in order to go out of Qishan to fight Cao Wei, Zhuge Liang raised troops and trained troops in Shuzhong, and also prepared military food and grass for this dispatch, and also generously wrote the famous article "Former Departure Table";

2, the second out of Qishan, in the battle with Sima Yi, Zhuge Liang's soldiers suffered heavy casualties, and when the supply of grain and grass was not enough, Zhuge Liang had to retreat, and the second out of Qishan died down;

3, three out of Qishan, Zhuge Liang in poor health, coupled with the bad news that Zhang Bao died in battle, made him have no intention of fighting again, and the Shu army retreated without a fight;

4, four out of Qishan, Sima Yi used a counter-plot to spread a large number of rumors in Shu, so that Liu Chan ordered Zhuge Liang to collect troops and return to Shu, Zhenqing Zhuge Liang's return to the division lost a good opportunity to win, and the four out of Qishan failed;

5, five out of Qishan, Zhuge Liang in order to fulfill the wish of his benefactor Liu Bei, in the absence of any chance of winning, five out of Qishan, the result is also a failure;

6, six out of Qishan, Zhuge Liang in the head-on battle with Sima Yi, said the bridge battle, Zhuge Liang really lost to the old opponent Sima Yi in strategy, so that the loss of thousands of soldiers in front of the reed, accumulated work into illness, and finally died of illness in Wuzhangyuan.

used to watch the TV series "Romance of the Three Kingdoms", Prime Minister Zhuge went out of Qishan six times, and every time he was about to succeed, he either retreated from the army due to the loss of the street pavilion, or returned to the division due to lack of food, or was recalled to the Northern Expedition by the latter due to the discord plan.

Now I read "Romance of the Three Kingdoms" again, and found that every time I went out on the Northern Expedition, the number of Shu troops was more than 300,000 and as little as 100,000. However, the Wei army also had three or four hundred thousand troops in defense, and the number of this army was only the troops deployed in the Guanzhong area.

Although Zhuge Liang was able to achieve some tactical victories with his resourcefulness, but throughout the entire campaign, the Shu army did not have much advantage, and with the development of the war, the best strategic result was also to enter a state of stalemate. If the Shu army wants to fight Chang'an, it can be said that it is difficult and almost impossible to achieve.

The first Northern Expedition closest to victory, even if the Shu army did not lose the street pavilion, at most it was to recover the counties of Longxi and strengthen its rule. The final standoff will remain in the area of Jieting and Chencang. Wei would strengthen its defenses around Chang'an.

Zhuge Liang's Northern Expedition, also known as Zhuge Liang's Northern Expedition to the Central Plains, was the Five Wars launched by Zhuge Liang, the prime minister of Shu Han during the Three Kingdoms period, in order to support the Han dynasty and unify the Central Plains, from the spring of 228 to the winter of 234, against Cao Wei. These five Northern Expeditions can be divided into: two major all-out wars, including the First Northern Expedition and the Fifth Northern Expedition; a medium-sized regional war, the Fourth Northern Expedition; Two small local wars, including the Second Northern Expedition and the Third Northern Expedition.

Regarding the motives of Zhuge Liang's Northern Expedition, according to expert research, it can be summarized into three points. First: In order to repay the emperor, in order to fulfill his last wishes.

Zhuge Liang's Northern Expedition was to repay the first emperor Liu Bei for his kindness and fulfill the last wish of the first emperor to restore the Han Dynasty. Second: If you don't attack Cao Wei, Shu Han will die.

Zhuge Lianghuai Beidu had realized that if Cao Wei was given time to develop his national strength, then the gap between Shu and Wei would become wider and wider. Once Cao Wei is strong, Shu can only sit and wait for death. Therefore, the Northern Expedition could only be carried out preemptively.

Third: the Northern Expedition to the Central Plains of the lead nucleus, the transfer of contradictions. Zhuge Liang launched the Northern Expedition, which could transfer the internal contradictions of Shu to the external contradictions of Cao Wei, and at the same time, it could also give Shu a chance to win the Central Plains.

Some people think that Zhuge Liang's Northern Expedition was a reckless military force and a way to bring about his own destruction. Zhuge Liang has made five Northern Expeditions, and only the first and fifth Northern Expeditions can shake the national strength of Shu.

However, in the first Northern Expedition, the Shu army did not damage except for a slight loss of soldiers and horses in Jieting, and all the soldiers and civilians of the three large counties of Tianshui, Nan'an and Anding were moved to Hanzhong, which greatly expanded the national strength of Shu. As for the Fifth Northern Expedition, the biggest loss of the Shu army was the death of Zhuge Liang, and other circumstances did not suffer any damage from the rolling brigade to shake the country's capital. Therefore, from the above point of view, Zhuge Liang's five northern expeditions did not greatly damage the national strength of Shu.
