On the fourth day of the April 1 of the first year of Wei Ganlu (256), Emperor Wei Cao Mao gave the general Sima Zhao a dragon embroidered dress and crown, plus a pair of red wooden boots worn by the emperor.
月4
月19th year of Yanxi in Shu Han (256), Shu Kingdom Jiang Wei was promoted to general.
After Jiang Wei withdrew his troops, he was stationed in Zhongti.
The generals of the Wei State discussed the strategy against Shu, and most of them believed that Jiang Wei's troops had been exhausted and it was impossible to go on a war again.
General Anxi Deng Ai disagrees with this view and said: "Our failure in Taoxi is not a small loss. The soldiers are seriously disabled and very weak. The grain warehouse is empty and the people are displaced. From a strategic perspective, they have the strength to march with victory, but our current situation is weak. This is one. The officers and soldiers are familiar with each other, and their weapons are complete and sharp. We have replaced the generals and updated the soldiers, and their weapons are not complete. This is two. They are marching by boat, and we are marching on land, working and leisure Different, this is three. Didao, Longxi , Nan'an and Qishan should be guarded. They attacked one place, but we were divided into four directions. This is four. They could eat the grain of the Qiang people on the spot. If they marched towards Qishan, there were thousands of hectares of ripe wheat there, which was enough to become their external granary. This is five. The enemy has always been cunning and good at calculating, so it is inevitable that they will attack. "
Under Deng Ai's insistence, the Wei army stepped up preparations for war and prepared to face the enemy.
In June, Jiang Wei and the general of Zhenxi Hu Ji agreed to meet in Shangqiu (now Tianshui, Gansu) to attack the Wei State.
In July, Jiang Wei took the lead in sending troops to Qishan (now southeastern mountainous land in Gansu). Hearing that Deng Ai was prepared, he withdrew his troops and returned and instead attacked Nan'an (now southeastern Longxi, Gansu) from Dongting (now south of Wushan, Gansu).
Deng Ai took the lead in occupying Wucheng Mountain (now southwest of Wushan, Gansu), held on the dangerous side and resisted Jiang Wei.
Jiang Wei failed to attack and lost the geographical advantage. That night, he crossed Weishui and walked eastward, and advanced along the mountain road.
The two armies fought in Duangu (now southwest of Tianshui, Gansu).
Because Hu Ji did not come to support him at the agreed time and place, Jiang Wei was unable to support him and was defeated by Deng Ai.
Shi soldiers were scattered, with many casualties.
This is the first time that Jiang Wei has suffered a defeat since the Northern Expedition of . Shu people blamed Jiang Wei for this. The State of Wei finally broke the myth of Jiang Wei's undefeated, greatly encouraging the morale and confidence of the Wei army.
Jiang Wei returned from defeat and wrote a letter to apologize, so he asked for a demotion, and changed it to General Wei, acting as a general.
Deng Ai predicted the enemy accurately before the battle, and due to changes in mechanisms during the battle, he always held the initiative in the battle, leaving valuable experience for later defensive operations.
Cao Mao issued an edict to praise Deng Ai, and appointed Deng Ai as the general of Zhenxi, governing the military affairs of Longyou, and was appointed Deng Hou, and divided his son Deng Zhong, and became Ting Hou.
In August, Cao Mao ordered Sima Zhao to increase the title of governor, and report the matter without being named. He went to the army to hold Huang Yue and appointed the Taiwei Sima Fu as the Taifu.
In September, Situ Gaorou was appointed as the Grand Marshal.
