Cao Xiu

Historical Record

Cao Xiu, courtesy name Wenlie, was a clansman's son of Cao Cao. When the realm fell into chaos, Cao Xiu lost his father while barely more than ten years old; alone, with a single retainer, he attended to the funeral and carried his aged mother across the Yangtze into the land of Wu. Later, because Cao Cao had raised a righteous army, he changed his name, made his way through Jing Province, and finally returned north by back roads to gain an audience with Cao Cao. Upon seeing him, Cao Cao praised him as "the thousand-li colt of my house," and had him lodge with Cao Pi, treating him as a son^[1].

Cao Xiu often accompanied Cao Cao on campaign and once led the Tiger and Leopard Cavalry as palace guards. In the twenty-third year of Jian'an (218 CE), when Liu Bei sent his general Wu Lan to garrison Xiabian, Cao Cao dispatched Cao Hong to campaign against him, appointing Cao Xiu Cavalry Commandant to participate in Cao Hong's military affairs. Cao Cao specifically instructed Cao Hong, "Though you are an army adviser, in truth he is the commander." Cao Hong therefore entrusted Cao Xiu with great responsibility. At that time Liu Bei also sent Zhang Fei to garrison Gushan, intending to cut off the Wei army's rear. While the generals argued back and forth, Cao Xiu held, "If the enemy truly meant to cut the road, he would move in stealth with hidden troops. Now he first makes a show of force—this proves he cannot do it. We should strike Wu Lan before they gather; once Wu Lan is broken, Zhang Fei will withdraw of himself." Cao Hong adopted his counsel, advanced and broke Wu Lan, and Zhang Fei indeed withdrew^[1].

After Cao Cao captured Hanzhong and the armies returned to Chang'an, Cao Xiu was appointed Central Commander of the Army. After Cao Pi ascended the throne of King of Wei, Cao Xiu was appointed General Commander of the Army and, for his cumulative merits, enfeoffed as Marquis of Dongyang Precinct. After Xiahou Dun died, Cao Xiu was appointed General Who Guards the South, granted the staff of authority and command over all military affairs. Cao Pi personally saw him off, stepping down from his carriage to clasp his hand in farewell^[1].

During his tenure, Cao Xiu fought Sun's Wu on several occasions. When Sun Quan once sent a general to garrison Liyang, Cao Xiu broke him upon arriving, then sent troops across the Yangtze and burned the Wu army's encampments of several thousand households at Wuhu. He was later promoted to General Who Conquers the East and made Inspector of Yang Province, advanced to Marquis of Anyang Village. When Cao Pi personally campaigned against Sun Quan, he made Cao Xiu Grand General Who Conquers the East, granted the yellow battle-axe, and put him in command of Zhang Liao and others, together with more than twenty armies of the various provinces and commanderies, defeating Sun Quan's great general Lü Fan and others at Dongpu^[1].

After Emperor Ming, Cao Rui, took the throne, Cao Xiu was advanced to Marquis of Changping. When the Wu general Shen De garrisoned Wan, Cao Xiu broke him and slew Shen De. The Wu generals Han Zong, Zhai Dan, and others also led their followers in surrender to Cao Xiu one after another. Cao Xiu thus had his fief increased by four hundred households, for a total of two thousand five hundred households with the earlier grants, and was promoted to Grand Marshal, still commanding Yang Province as before^[1].

In the second year of Taihe (228 CE), Emperor Ming divided his forces along two routes to campaign against Sun's Wu: Sima Yi advanced down the Han River, while Cao Xiu led the armies toward Xunyang. A Wu general feigned surrender, and Cao Xiu credulously plunged in deep, with the result that the campaign went badly, and he withdrew to encamp at Shiting. At night the army fell into panic, the soldiers scattered, and a great quantity of armor, weapons, and baggage was abandoned. Cao Xiu submitted a memorial confessing his fault; Emperor Ming sent the Commandant of the Encamped Cavalry, Yang Ji, to comfort and reassure him, bestowing lavish rewards. Yet Cao Xiu, from this, suffered an abscess on his back and died, with the posthumous title of Marquis Zhuang^[1].

In the Novel

*Romance of the Three Kingdoms* portrays Cao Xiu in a manner that largely follows the historical record but with literary embellishment that makes his image more vivid. In the novel, Cao Xiu's first appearance displays his youthful martial spirit. When Cao Cao held an archery contest on the drill field, Cao Xiu, as a son of the Cao clan, struck the bullseye with a single arrow, delighting Cao Cao, who called him "the thousand-li colt of my house"^[2]. Although this episode is not recorded in history, it echoes Cao Cao's appraisal of him as a "thousand-li colt" in the histories and reinforces his image of early success.

In the novel, after Cao Pi ascended the throne, Cao Xiu was appointed Commander-in-Chief of the Imperial Forest Army, responsible for guarding the capital^[3]. When Cao Pi was gravely ill and entrusted his heir, Cao Xiu, together with Cao Zhen, Chen Qun, and Sima Yi, received the testamentary edict to assist the young ruler Cao Rui^[4]. After Cao Rui took the throne, Cao Xiu was enfeoffed as Grand Marshal and commanded the troops of Yong and Liang, holding an exalted position^[4].

The novel emphasizes Cao Xiu's crushing defeat at the Battle of Shiting. The Wei ruler Cao Rui believed Eastern Wu's Zhou Fang's stratagem of feigned surrender and dispatched Cao Xiu, Jia Kui, and Sima Yi along three routes to campaign against Wu. Cao Xiu credulously trusted Zhou Fang, ignored Jia Kui's remonstrance, and even wished to behead Jia Kui, ultimately falling into Lu Xun's ambush at Shiting^[5]. In the novel, Cao Xiu was routed by Lu Xun at Shiting, suffered heavy losses, and was nearly annihilated, escaping only thanks to Jia Kui's rear-guard^[6]. This crushing defeat led to Cao Xiu "growing ill from anxiety; upon reaching Luoyang, an abscess erupted on his back and he died"^[7], consistent with the histories' record of "an abscess erupting on his back and his death," but the novel attributes it to the shame and resentment of defeat, making it more dramatic.
