The Battle of Dushi Ford was a battle fought between the warlords Cao Cao and Yuan Shao in the first lunar month of 200 in the late Eastern Han dynasty. In the battle, Yuan Shao launched an attack on Cao Cao's position on the southern bank of the Yellow River, taking advantage of Cao's temporary absence. In response, Cao Cao's general Yu Jin raided Yuan Shao's encampments in the vicinity of present-day Henan, ultimately discouraging Yuan from making a determined attack. ==Background== By the end of the 190s, northern China was divided between two contending warlords, Yuan Shao and Cao Cao. Each had assimilated the smaller powers around them and made political arrangements with the larger powers elsewhere, and were increasingly looking at each other for potential gains. Cao Cao had earlier secured the helpless Emperor Xian into his custody, a move that Yuan Shao regretted not to have made. After the successful conquest of Gongsun Zan's territories to the north, Yuan Shao turned to the south to prepare for an assault on Cao Cao in the summer of 199.〔Leban, p. 335〕 In response, Cao Cao went on a patrol to the northern front and dispatched several armies to defend positions on the south side of the Yellow River in the eighth lunar month (September 8 - October 7) of 199. Among these was the placement of Yu Jin at Yan Ford (延津; north of present-day Yanjin County, Henan) with 2,000 troops.〔Leban, p. 342〕 This position blocked Yuan Shao's direct approach over the ford toward Cao Cao's main defense lines at Guandu (官渡; northeast of present-day Zhongmu County, Henan).〔de Crespigny (2007), p. 996〕 After his patrol of the front, Cao Cao returned to the capital at Xu City and made further preparations for the future confrontation with Yuan Shao at Guandu. At this time, Yuan Shu, Yuan Shao's cousin who had declared himself "Son of Heaven", turned over his claim to the throne to Yuan Shao and made his way across Cao Cao's territory to reach Yuan Shao's son Yuan Tan in Qing Province. Cao Cao sent Liu Bei and Zhu Ling to block Yuan Shu from getting through, and they succeeded, leaving Yuan Shu to die in infamy in the twelfth lunar month.〔Leban, p. 347 note 63〕 Liu Bei, however, did not return from this campaign and settled his men in Xu Province (徐州) in open rebellion. Cao Cao was determined to eliminate Liu Bei before his forces could accumulate, but Cao Cao's generals remonstrated against any immediate action against Liu Bei, fearing that Yuan Shao might exploit the opportunity to attack Xu City when Cao Cao was away attacking the east. Cao Cao and his strategist Guo Jia disagreed with the generals, saying that Liu Bei would become troublesome if not dealt with immediately, and Yuan Shao would be too slow and indecisive to make a move in time.〔Leban, p. 351〕 Cao Cao went ahead with his plan and attacked Liu Bei personally in Xu Province. Tian Feng, the aide-de-camp (別駕) in Yuan Shao's Ji Province (冀州), urged Yuan Shao to grasp this opportunity to mount an attack on Cao Cao's rear, but Yuan excused himself on the grounds that one of his sons was sick. Tian Feng, in dismay, struck the ground with his staff and said: "Alas, in the critical moment he throws away opportunity for the sake of a sick child. The pity of it, the chance is lost."〔de Crespigny (1996), Jian'an 4: C〕 However, that is not to say that Yuan Shao did not attempt to make use of Cao Cao's temporary absence. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Battle of Dushi Ford」の詳細全文を読む スポンサード リンク
