Hu Dahai (?) 1362), a general in the early Ming Dynasty. The word Tongfu. A native of Hongxian (now Sixian County, Anhui). Hu Dahai had excellent intelligence and repeatedly broke through the enemy's formation, but was killed by the villain. Zhu Yuanzhang was posthumously named the Duke of Yue Guo, and he was called "Wuzhuang".
When Ming Taizu Zhu Yuanzhang first raised his army, Hu Dahai defected to him. Zhu Yuanzhang saw his mighty appearance and immediately appointed him as a striker.
After Hu Dahai joined the army, he followed Taizu across the river and occupied many places with the generals. He was awarded the title of Marshal of the Right Wing Unified Army for meritorious service. He followed Deng Yu to break through Ningguo, occupy Huizhou, and pacify this area, and he also guarded here. Soon after, the Yuan general Yang Wanzhi attacked them with 100,000 soldiers and horses, and Hu Dahai engaged the enemy under the city, and the battle was very fierce. Hu Dahai took the lead and rushed into the enemy formation, the Yuan soldiers retreated, and Zhu Yuanzhang's army quickly pursued and defeated the Yuan army. In this way, Hu Dahai, together with Deng Yu and Li Wenzhong, set out from Yuling Pass to attack Jiande (now Zhejiang). At Chun'an, the Yuan army was defeated, and then Jiande was occupied. Hu Dahai then defeated Yang Wanzhi in succession, capturing more than 30,000 enemies. Hu Dahai was thus promoted to the rank of Judge of the Privy Council. After capturing Lanxi and Wuzhou, he was promoted to the rank of Privy Councillor.
After capturing Zhuji, the Yuan army defenders fled in a hurry in the dark night. Shen Sheng, who had surrendered, rebelled soon after, and Hu Dahai led his army to defeat the rebels and capture more than 4,000 people alive. So he renamed Zhuji Zhujinzhou, and then led his troops to save Shaoxing, defeating Zhang Shicheng's troops many times. Taizu Zhu Yuanzhang thought that Ningzhou and Yuezhou were important places, so he ordered Hu Dahai to guard these places. After Zhang Shicheng's first few failures, he sent the general Lu Zhen to besiege Zhujin. Hu Dahai led a large army to rescue, and Lu Zhen dug the embankment of the river and flooded the city with water, in a vain attempt to drown Hu Dahai and them in the city. Hu Dahai led his army to the dam, occupied the embankment, and then discharged the water to Lü Zhen's camp. Seeing that the situation was urgent, Lu Zhen was forced to come to Hu Dahai and swore an oath to ask for a strike. Hu Dahai agreed. Then, Hu Dahai led an army to attack Chuzhou, and the Yuan general Shi Mo Yisun fled, and the seven towns of Chuzhou were all pacified.
In the twentieth year of Yuan Zhizheng (1360), Chen Youliang invaded Longjiang, and Taizu ordered Hu Dahai to attack Xinzhou (now Shangrao, Jiangxi) in order to contain Chen Youliang. Hu Dahai led the army to Lingxi, and about several thousand cavalry and infantry in Guangxin City came out to meet the battle, and the sea quickly defeated these foot cavalry. Chase to the city and command the soldiers to attack the city. The army defending the city resisted for a while, but could not resist it and fled one after another, so Hu Dahai captured Guangxin.
In the twenty-second year of Yuan Zhizheng (1362), after Zhu Yuanzhang's army captured Yanzhou (now Jinhua, Zhejiang), Hu Dahai guarded Yanzhou, and Miao generals Jiang Ying, Liu Zhen, and Li Fu returned from Tonglu. Hu Dahai saw that they were all fierce and brave, and he liked them very much, so he kept them all under his hands. As a result, Jiang Ying and others surrendered to Zhang Shicheng and plotted to kill Hu Dahai.
