Sun Ce's conquests in Jiangdong were a series of military campaigns by the warlord Sun Ce to conquer territories in the Jiangdong and Wu regions from 194 to 199 towards the end of the Eastern Han dynasty. The conquered lands served as a foundation for the state of Eastern Wu during the Three Kingdoms period (220–280).
Background
Sun Ce was the eldest son of the warlord Sun Jian, who was killed in action during the Battle of Xiangyang in 191 against Liu Biao, the Governor of Jing Province. Although Sun Ce was 16 when his father died, he was already well-known and was acquainted with many reputable men.
In 194, Sun Ce went to meet the warlord Yuan Shu, to whom his father was previously subordinate. Yuan Shu was surprised to see Sun Ce, but he refused to return the command of Sun Jian's troops to Sun Ce. At the time, Sun Ce's maternal uncle Wu Jing, the Administrator of Danyang Commandery, was also a subordinate of Yuan Shu. Yuan Shu then ordered Sun Ce to travel to Danyang Commandery and rally his own troops there. Although he managed to muster about a few hundred men, Sun Ce came under attack by Zu Lang (祖郎), a bandit leader in Jing County, and almost lost his life. Sun Ce met Yuan Shu again later. This time, Yuan Shu agreed to return about 1,000 of Sun Jian's troops to Sun Ce. Yuan Shu also initially promised to let Sun Ce be the Administrator of Jiujiang Commandery, but he went back on his word and appointed Chen Ji instead. Yuan Shu planned to attack Xu Province, so he requested 30,000 hu of grain from Lu Kang, the Administrator of Lujiang Commandery, as supplies for his army. However, Lu Kang refused to provide the grain. Sun Ce bore a grudge against Lu Kang because the latter belittled him before. Yuan Shu then sent Sun Ce to attack Lu Kang and told him before he left, "It was my mistake to appoint Chen Ji, and now I often regret not abiding by my original decision. If you defeat Lu Kang, Lujiang will truly be yours." However, Yuan Shu broke his promise again after Sun Ce conquered Lujiang Commandery as he appointed Liu Xun as the Administrator instead. Sun Ce became disappointed with Yuan Shu. In the meantime, Sun Ce had gained the support of other notable persons in Wu territory, such as Ling Cao and Zhou Tai.
Around the time, the territories in Yang Province were under the jurisdiction of Liu Yao, who had been appointed as the Inspector of Yang Province by the Han central government. However, Liu Yao only controlled the four commanderies of Danyang, Wu, Kuaiji and Yuzhang, with Jiujiang and Lujiang (both located north of the Yangtze River) out of his control. Shouchun was initially the capital of Yang Province, but since it was under Yuan Shu's control, Liu Yao moved the provincial capital of his administration to Qu'e County. Liu Yao drove away Wu Jing, the Administrator of Danyang Commandery appointed by Yuan Shu. Wu Jing and Sun Ben (the former Commandant of Danyang, and a cousin of Sun Ce) retreated to Liyang County. As a defensive measure against Wu Jing, Liu Yao ordered Fan Neng (樊能) and Yu Mi (于糜) to garrison at Hengjiang Ford (southeast of present-day He County, Anhui), Zhang Ying (張英) to defend Danglikou (east of present-day He County, Anhui). Yuan Shu appointed his follower Hui Qu (惠衢) as the Inspector of Yang Province and Wu Jing as Military Inspector-General of the Household, and then sent them along with Sun Ben to attack Liu Yao's forces.
The conquests
Campaign against Liu Yao
In 195, Sun Ce requested permission from Yuan Shu to assist Wu Jing in fighting Liu Yao. Yuan Shu agreed and appointed Sun Ce as Colonel Who Breaks and Charges (折衝校尉) and acting General Who Exterminates Bandits (殄寇將軍). Sun Ce initially had about 1,000 troops, tens of warhorses and hundreds of followers. When he reached Liyang County (present-day He County, Anhui), he had rallied about 5,000 to 6,000 men. Sun Ce's army then crossed the Yangtze River and attacked Liu Yao's base at Niuzhu, obtaining much weapons and provisions. Some time earlier, Xue Li (薛禮), the Chancellor of Pengcheng, and Ze Rong, the Chancellor of Xiapi, both led troops southward and supported Liu Yao as their leader. Xue Li garrisoned at Moling (present-day Nanjing, Jiangsu) while Ze Rong fortified his base at south of Moling. Sun Ce attacked Ze Rong first, defeating him and killing more than 500 of Ze's men. Ze Rong retreated to Moling and remained in the city.
Sun Ce turned his attention towards attacking Xue Li but Xue escaped. At this time, Fan Neng and Yu Mi combined forces to besiege Niuzhu. When Sun Ce heard of that, he returned to break the siege, defeated Fan Neng and Yu Mi, and brought thousands of civilians under his control with his victory. Sun Ce then headed back to attack Ze Rong, but was wounded by a stray arrow during the battle so he stayed in the camp at Niuzhu. To lure Ze Rong out of Moling, Sun Ce ordered his soldiers to spread false rumours that he had died from his injury. Ze Rong fell for the ruse and sent his subordinate Yu Zi (于茲) to attack Sun Ce. Sun Ce sent a few hundred men to engage Yu Zi and lure him into an ambush, where Yu Zi suffered a crushing defeat. Sun Ce then went to Ze Rong's camp and ordered his men to shout, "So, what do you think of Sun Ce now?" Yu Zi was terrified and escaped at night.
When Ze Rong learnt that Sun Ce was still alive, he immediately strengthened his defences by ordering deeper trenches to be dug and higher ramparts built. As Ze Rong was in a strategic defensive position, Sun Ce abandoned the assault. Sun Ce defeated Liu Yao's forces at Hailing, conquered Hushu and Jiangcheng, and led his troops to besiege Qu'e County, the administrative centre of Liu Yao's territories. Around this time, Taishi Ci arrived from Donglai to assist Liu Yao. Although his subordinates advised him to make good use of Taishi Ci in resisting Sun Ce, Liu Yao was suspicious of Taishi Ci and did not dare to let Taishi Ci assume important responsibilities.
One day, when Taishi Ci was scouting outside Qu'e County, he encountered Sun Ce at Shen Village. Sun Ce had about 13 riders accompanying him at the time, including Han Dang, Huang Gai and Song Qian. Taishi Ci knew that the lead rider was Sun Ce so he rode forth to challenge Sun Ce to a duel. During the fight, Sun Ce managed to grab one of Taishi Ci's jis but he also lost his helmet to his opponent. By then, reinforcements from both sides had arrived so Sun Ce and Taishi Ci retreated to their respective bases.
Not long later, Liu Yao was defeated in battle by Sun Ce and his troops abandoned the city and fled. After occupying Qu'e County, Sun Ce rewarded his men and issued an order to the people: "Those who previously served Liu Yao and Ze Rong will not be subject to questioning if they surrender. For those who wish to join the army, one man from each household is sufficient; those who are unwilling will not be compelled." Within one day, Sun Ce succeeded in rallying more than 20,000 troops and 1,000 warhorses.
Meanwhile, Liu Yao and Ze Rong retreated to Yuzhang Commandery. Ze Rong used a scheme to kill Zhu Hao, the Administrator of Yuzhang Commandery, and take over the commandery. Liu Yao led an army from Pengze County (present-day Hukou County, Jiangxi) to attack Ze Rong. Ze Rong fled into the hills after his defeat and met his end at the hands of the natives. The Han central government then appointed Hua Xin as the new Administrator of Yuzhang Commandery to replace Zhu Hao.
While these events were happening in Yuzhang Commandery, Zhu Zhi, one of Sun Ce's subordinates, defeated Xu Gong and seized control of Wu Commandery for his lord. Xu Gong escaped from Wu Commandery and joined the bandit leader Yan Baihu.
Campaign against Wang Lang
In 196, Sun Ce's subordinates advised him to attack Yan Baihu, but Sun Ce said, "Yan Baihu and his bandits do not have great aspirations. I'll capture them later eventually." Sun Ce then led his troops on a detour, bypassing Yan Baihu's position at the south of Wu Commandery, and proceeded to attack Wang Lang, the Administrator of Kuaiji Commandery along the southern shore of Hangzhou Bay. Yu Fan, an officer under Wang Lang, advised his lord to avoid Sun Ce since they were weaker in terms of military strength. As Sun Ce advanced towards Kuaiji Commandery, Wang Lang moved to defend his territory on the line of the Qiantang estuary at the head of Hangzhou Bay. During his march through Wu Commandery, Sun Ce used the opportunity to rally support from his connections in the region. Sun Ce's uncle, Sun Jing, responded and joined him at Qiantang.
Wang Lang's army was stationed at Guling, where Sun Ce attempted several times to force his way through but failed. Sun Ce then heeded Sun Jing's suggestion and arranged for his uncle to lead a detachment south to a river crossing at Zhadu County (southwest of present-day Xiaoshan District, Zhejiang). From there, Sun Jing headed back to attack Wang Lang's forces at Gaoqian County (northwest of present-day Shaoxing, Zhejiang). That night, Sun Ce then ordered his remaining troops to light the usual number of campfires even though they had less troops, so as to create an illusion that his army's strength was still the same. While Wang Lang was taken by surprise, Sun Ce's forces quickly established a position across the river.
Initially, Wang Lang attempted to organise a retreat and regroup his troops, so he sent Zhou Xin to hold the line against Sun Ce's attack. Sun Ce defeated and killed Zhou Xin, forcing Wang Lang to abandon his territories and escape south to Dongye by sailing along the coast. Wang Lang later surrendered to Sun Ce and spent two years in the region before returning to the Han central government in Xuchang.
Sun Ce appointed himself as the Administrator of Kuaiji Commandery and recruited Yu Fan to serve under him. By 197, Sun Ce had already established a strong foothold in the Jiangdong region and broke off relations with Yuan Shu. In 198, the Han central government promoted Sun Ce to General Who Attacks Rebels (討逆將軍) and enfeoffed him as the Marquis of Wu (吳侯). In addition, Sun Ce's younger brother Sun Kuang married Cao Cao's niece, while Cao Cao's son Cao Zhang married the daughter of Sun Ben (Sun Ce's cousin).
Campaign against Yan Baihu, bandits and the Shanyue
When Sun Ce defeated Wang Lang, the Prime Minister Cao Cao appointed Chen Yu (陳瑀) from Haixi (southeast of present-day Guannan County, Jiangsu) the Administrator of Wu Commandery. Chen Yu secretly plotted to ally with Yan Baihu to attack Sun Ce. However, Sun Ce sent a naval detachment led by Lü Fan to launch a surprise attack against Chen Yu while he defeated Yan Baihu. Chen Yu was quickly driven out and fled to join Yuan Shao, whose territory was far away from Sun's.
In 198, Yuan Shu sent a messenger to Zu Lang, a bandit leader in Danyang Commandery, promising to grant him an official post if he would oppose Sun Ce. Previously, after Liu Yao's defeat, Taishi Ci escaped to the hills around present-day Wuhu City. He appointed himself as the Administrator of Danyang Commandery and moved to Jing County, where he amassed a large number of Shanyue followers.
After pacifying eastern Danyang Commandery, Sun Ce led his troops to attack Zu Lang at Lingyang County (west of present-day Taiping County, Anhui) and captured him. Although Sun Ce almost lost his life in an earlier battle against Zu Lang before he started his conquests, he spared Zu Lang and allowed him to serve as his subordinate. Later, Sun Ce defeated Taishi Ci at Yongli County (in present-day Jing County, Anhui) and captured him. Sun Ce freed Taishi Ci and succeeded in persuading him to be his subordinate. When Sun Ce's army marched back in triumph, both Taishi Ci and Zu Lang were in the lead. With his victory, Sun Ce gained control over the six counties west of Jing County and fully secured three commanderies in the Jiangdong region.
