Jiang Shu

Historical Record

Jiang Shu was a general of Shu Han during the Three Kingdoms period who, in the later years of Shu Han, held the post of Commander of Wuxing. However, his performance in office was unsatisfactory, and he was judged to have "achieved nothing of note in his duties" ^c:6183. The Shu Han court therefore decided to dispatch someone else to replace him, while Jiang Shu was kept on to assist in the defense of the Hanzhong region. Resentful of this arrangement, Jiang Shu harbored discontent, which foreshadowed his later conduct ^c:6183.

In the sixth year of the Jingyao era (263 CE), Cao Wei launched a massive campaign against Shu. Zhong Hui led a great army to attack Hanzhong, and one detached force was ordered to assault Yang'an Pass. At this time, Jiang Shu was garrisoning Yang'an Pass together with Fu Qian. Facing the Wei army's assault, Jiang Shu chose to open the gates and surrender, betraying Shu Han. In stark contrast, Fu Qian held firm and unyielding, and ultimately perished heroically in combat ^c:6183. Jiang Shu's surrender directly caused the fall of Yang'an Pass, allowing Zhong Hui to drive straight in and deal a severe blow to Shu Han's defensive system. This act of his is explicitly recorded in history as "opening the gates to surrender" ^c:6183, and was one of the important factors leading to the fall of Shu Han.

In the Novel

In Romance of the Three Kingdoms, Jiang Shu's image is given more detail and drama. He first appears in the first year of the Jingyao era of Shu Han (258 CE), when Jiang Wei was selecting generals in Hanzhong. Jiang Shu was chosen along with Fu Qian and was praised by Jiang Wei as "rather bold and valiant" ^c:3212. This forms a sharp contrast with the historical record of "achieving nothing of note in his duties"; in the novel, Jiang Shu is initially portrayed as a general of promise.

However, when the Wei army attacked Yangping Pass, Jiang Shu's character flaws and his eventual betrayal are displayed in full. As Zhong Hui's great army bore down, Jiang Shu argued that "holding firm is best," believing the Wei forces were too strong to resist by force ^c:6184. This clashed with Fu Qian's argument for active engagement. When Zhong Hui called on him to surrender, Jiang Shu "remained silent and gave no answer," revealing his inner wavering and hesitation ^c:6184. Ultimately, when Fu Qian went out of the pass to meet the Wei army in battle, Jiang Shu seized the opportunity to betray him, raising the Wei banner atop the pass and shouting, "I have already surrendered to Wei!" ^c:6184. This act not only drove Fu Qian into a hopeless plight but also thoroughly exposed Jiang Shu's traitorous nature. The novel also depicts Fu Qian's bitter rebuke of Jiang Shu: "You ungrateful, treacherous villain—with what face will you look upon the Son of Heaven!" ^c:6184, further reinforcing Jiang Shu's negative image.

In the novel, after surrendering, Jiang Shu also took part in the interaction between Zhong Hui and Jiang Wei. When Zhong Hui patrolled Mount Dingjun and, sensing the strange apparition of the manifested spirit of Marquis Wu Zhuge, asked the surrendered general Jiang Shu whether there was a divine temple at Mount Dingjun, Jiang Shu answered: "There is no divine temple, only the tomb of Marquis Wu Zhuge." ^c:13430 Although this episode is a fabrication of the novel, it indirectly reflects Jiang Shu's standing and role within the Wei army as a surrendered general.

* Jiang Wei (serves): In Romance of the Three Kingdoms, Jiang Shu was once a general under Jiang Wei and was esteemed by him for his courage ^c:3212 (novel only).

Fu Qian held firm and died for his cause, while Jiang Shu opened the gates and surrendered—forming a stark contrast and antagonism between them ^c:6183.

Iconic Scenes

* Opening the gates to surrender at Yang'an Pass: This is the most iconic event of Jiang Shu's life. When the Wei army attacked Yang'an Pass, Jiang Shu chose to betray Shu Han and open the gates to surrender, directly causing the fall of the pass. This scene is briefly recorded in the Records of the Three Kingdoms as "Jiang Shu opened the gates to surrender" ^c:6183, while in Romance of the Three Kingdoms it is depicted more vividly, including his dispute with Fu Qian, his silent refusal to answer, and his final cry of "I have already surrendered to Wei!" ^c:6184.
* The dispute with Fu Qian over fighting versus holding: In Romance of the Three Kingdoms, Jiang Shu's argument with Fu Qian before Yangping Pass over strategy fully reveals the differing characters and stances of the two men. Jiang Shu advocated "holding firm is best," while Fu Qian advocated going out to fight—a dispute that foreshadowed Jiang Shu's eventual surrender ^c:6184 (novel only).
* The dialogue at Mount Dingjun about the tomb of Marquis Wu Zhuge: In Romance of the Three Kingdoms, after surrendering, Jiang Shu mentioned to Zhong Hui that there was the tomb of Marquis Wu Zhuge at Mount Dingjun, indirectly explaining the apparition of the "manifested spirit of Marquis Wu" that Zhong Hui had seen ^c:13430 (novel only). Though a fictional episode, it became a distinctive appearance for Jiang Shu in the novel.
