Du Yu

Historical Record

Du Yu's life and deeds are not clearly recorded in the official histories such as the Records of the Three Kingdoms. As a result, regarding Du Yu's origins, early experiences, official career, and his specific contributions in history, we cannot obtain definite information from the surviving historical materials. This makes Du Yu's image in the official histories relatively obscure, and his historical standing and role difficult to verify through the sources.

In the Novel

In Luo Guanzhong's historical novel Romance of the Three Kingdoms, Du Yu, as one of the key figures in the Western Jin conquest of Wu, is portrayed quite vividly. When he first appears, the Prince of Jin, Sima Yan (Emperor Wu of Jin), adopting Yang Hu's advice, appointed him Grand General Who Guards the South, with command over the military affairs of Jing Province^[1]. The novel describes Du Yu's character in detail, calling him "a man mature and seasoned, untiring in study, who most loved reading Zuo Qiuming's Spring and Autumn Commentary, carrying it with him whether sitting or lying down, and whenever he went out he would always have someone hold the Zuo Commentary before his horse, so that people of the time called him the 'Zuo Commentary addict'"^[1]. This detail not only highlights his erudition but also lends him a distinctive personal charm. Du Yu was ordered to garrison Xiangyang, where he comforted the people and trained the troops, actively preparing for the campaign against Wu.

In the campaign to destroy Wu, Du Yu displayed outstanding military talent. He sent his forces out from Jiangling and cleverly used stratagems, dispatching his subaltern Zhou Zhi to lead eight hundred marines to secretly cross the Yangtze and make a night raid on Leixiang, creating a show of force to confuse the Wu army^[2]. The next day, Du Yu led his main host forward by both land and water, confronting the Wu generals Sun Xin, Lu Jing, and Wu Yan. He first feigned defeat to lure the enemy, and when Sun Xin pursued, he encircled him on all sides and routed the Wu army. Zhou Zhi took advantage of the chaos to raise fire atop the city, cutting Sun Xin down from his horse. Seeing the situation turning ill, Lu Jing tried to flee for his life but was also slain by the Jin general Zhang Shang. When the Wu general Wu Yan saw the cause was lost, he abandoned the city and fled, and was finally captured by an ambush, whereupon Du Yu showed no mercy and had him executed^[2]. After this battle, Du Yu's martial prestige rose greatly; the commanderies and counties around the Yuan and Xiang rivers surrendered at the mere sight of his banners, and Wuchang too fell without a fight.

At the strategic council on taking Jianye, faced with Hu Fen's suggestion that "the spring waters are rising and we cannot stay long; we may wait until next spring," Du Yu overruled the others, describing the present situation with the phrase "the momentum of splitting bamboo," firmly believing that Wu was like a stalk of bamboo: after a few joints, the rest would all split apart at the touch of the blade, with no place left to set one's hand^[3]. He insisted on pressing the advantage in pursuit, ultimately bringing about the total victory of the Jin army and hastening the fall of Wu. Through these episodes, the novel shapes Du Yu into the image of a scholar-general both wise and brave, decisive and resolute.
