From AD 238 to AD 262, during the 24 years, Jiang Wei's court made eleven northern expeditions, once every two years on average. Jiang Wei's will, determination and belief in the Northern Expedition are no less than Zhuge Liang's. The record of Jiang Wei's Northern Expedition was mixed, with two victories, the second and the eighth Northern Expedition respectively. Three small victories, namely the third, fourth and seventh northern expeditions;
There were four draws, namely 1, 5, 6, 10 Northern Expedition. A big defeat was the ninth Northern Expedition; A small defeat was 1 1 Northern Expedition; The First Northern Expedition: The Battle of Nan 'an which ended in a draw in 238 AD. Four years after Zhu Deliang's death, the then generals Jiang Wan and Jiang Wei led the troops out of Longyou together, and confronted Wei Jun in Nan 'an County, regardless of the outcome, but later retreated because of lack of food.
Nan 'an County was a county under the jurisdiction of Liangzhou at that time, belonging to Longyou area. Longyou has five counties: Nan 'an County, Tianshui County, Longxi County, Guangwei County and Anding County. Nan 'an County is located in the southwest of Longxi County, Gansu Province, about 480 kilometers away from Hanzhong, the site of Shuhan, which can be said to be quite far away. It took about a month to March from Hanzhong to Nan 'an, and the road was difficult at that time.
The Second Northern Expedition: The Battle of Prosperity and the Battle of Victory in Prosperity, in fact, strictly speaking, Cao Wei took the initiative to attack Shu Han, which took place in 244 AD. At that time, Cao Shuang, the general of Cao Wei, and Xia Houxuan, the general of the Western Expedition, led hundreds of Wei Jun and Luo Jiakou to attack Shu Han and Hanzhong. Wang Ping, the satrap of Shuhan and Hanzhong, took the initiative to attack and stopped Wei Jun in a busy place. Jiang Wei and Fei Yi led the troops to support Wang Ping's battle, defeated Wei Jun, and Cao Shuang fled back to Chang 'an.
Xingshi this place is today in the north of Yangxian County, Shaanxi Province, about 60 kilometers away from Hanzhong. This time, Shu Han should be regarded as a home game. The Third Northern Expedition: Battle of Taoxi. In 247 AD, Jiang Wei was promoted to General Wei. In the same year, the Qiang people in Liangzhou area of Wei betrayed Cao Wei and prepared to surrender to Shu Han. Jiang Wei led his troops out of Longyou to fight Guo Huai, the secretariat of Wei Yongzhou, and Xia Houba, the garrison of Shu. In this battle, Jiang Wei succeeded in welcoming the rebellious Qiang people back, and the leader of the Qiang people, Bai Hu, had no cure.
Taoxi is Lintao County and its surrounding areas in Dingxi City, Gansu Province today, about 580 kilometers away from Hanzhong. The fourth northern expedition: the battle of Taocheng, a small victory. In 249 AD, Guo Huai, the general of Wei Xizheng, and Chen Tai, the secretariat of Yongzhou, besieged the city in Qucheng (now Dongzhangnan, Min County, Gansu Province) and attacked those who returned to Shu. Jiang Wei led the army to resist, and at the same time sent Liao Hua troops to the south bank of Baishui to contain Wargo. Jiang Wei personally led the army to Taocheng. Because Wargo had occupied the city, Jiang Wei led the army to retreat. Taocheng is in the southwest of Lintan County, Gansu Province, about 570 kilometers away from Hanzhong.
The fifth northern expedition: Taoxi battle, draw. In 250 AD, Jiang Wei led an army out of Longyou, assisted by men, and fought Huai in Taoxi, and the two sides were tied. Taoxi is Lintao County and its surrounding areas in Dingxi City, Gansu Province today, about 580 kilometers away from Hanzhong.
The Sixth Northern Expedition: Battle of Nan 'an, draw. In 253 AD, General Fei Yi was assassinated by an assassin. Since then, Jiang Wei's Northern Expedition has never been restricted by anyone. When Fei Yi was here, Jiang Wei's Northern Expedition did not exceed 10,000 soldiers, which was restricted by Fei Yi. In the same year, Jiang Wei led tens of thousands of troops out of the stone camp to besiege Nan 'an County in Longyou, and Chen Tai, the secretariat of Wei, led the army to rescue him. Soon, Jiang was withdrawn. Nan 'an County is located in the southwest of Longxi County, Gansu Province, about 480 kilometers away from Hanzhong, where Shu Han is located.
The seventh northern expedition: the battle of Longxi, a small victory. In 254 AD, Jiang Wei led tens of thousands of troops out of Longxi Drip Road, and Li Jianju, the leader of Wei Drip Road, surrendered. Then, Jiang Wei attacked Wu Xiang and killed General Xu Zhi. Jiang Wei pursued the victory and successively captured Hejian, Heguan and Lintao, plundered the local people and moved the capital to Shu. Wu Xiang is the southeast of Longxi County in Gansu Province today, Heguan is the Baoan Dongxiang Salar Autonomous County in Jishishan, Gansu Province today, and Lintao is Dingxi City in Gansu Province today.
The Eighth Northern Expedition: The second Taoxi Campaign was a complete victory. In 255 AD, Jiang Wei led the way to fight with Wang Jing, the secretariat of Wei Yongzhou, in Taoxi. Jing Wang suffered a crushing defeat, and Wei Jun suffered tens of thousands of casualties. He handed over Didao City to wait for rescue, and Jiang Wei besieged Didao City. Wei sent Chen Tai, the general of the Western Expedition, to clear the way, and Jiang Wei withdrew. The Ninth Northern Expedition: Battle of Duangu, a crushing defeat. In 256 AD, Jiang Wei was promoted to general, and met with Hu Ji, the general of Zhenxi, at the meeting place, but Hu Ji didn't come, which led to Jiang Wei being defeated by Wei's Wargo in Duangu, causing heavy casualties and Jiang Wei's defeat.
Duan Gu is in the southwest of Tianshui City, Gansu Province, about 350 kilometers away from Hanzhong. The 10th Northern Expedition: Battle of Mangshui, draw. In 247 A.D., Jiang Wei took advantage of the civil strife in Wei, and when Zhuge Dan rose up against Sima's family in Huainan, Jiang Wei led his troops out of Luo, and Wei held Sima Wang and Wargo to the city, and Jiang Wei stationed troops to make water. For example, if Jiang Wei attacks, Wei Sima Wang and Wargo will retreat as soon as they gain a foothold. Mangshui is the Heihe River, a tributary of Weihe River in zhouzhi county, Shaanxi Province today, about 320 kilometers away from Hanzhong.
1 1 Northern Expedition: Battle of Houhe, slightly defeated. In 262 AD, Jiang Wei led an army out of Houhe River and was defeated by Wargo, so Jiang Wei had to retreat to the middle road. This is the year before the demise of Shu Han. Houhe River is in Lintao County, Gansu Province, about 580 kilometers away from Hanzhong.
It can be seen that most of Jiang Wei's northern expedition attacked Longyou area, and the farthest was Lintao County and its surrounding areas in Dingxi City, Gansu Province, about 580 kilometers away from Hanzhong.
