Sun Gao (Wu)

Biography & Historical Record

Sun Gao (孙暠, Tôn Cảo), courtesy name unknown, was an Eastern Wu military officer and prominent member of the Sun imperial clan during the late Eastern Han and Three Kingdoms period. Hailing from Fuchun County, Wu Commandery (present-day Fuyang, Zhejiang Province), he was the eldest son of Sun Jing (孙静, Tôn Tĩnh), the loyal younger brother of Wu founding progenitor Sun Jian (孙坚). His younger brothers included esteemed military commanders Sun Yu (孙瑜), Sun Jiao (孙皎), and Sun Huan (孙奂).

During the rapid territorial consolidation of Jiangdong led by his cousin Sun Ce (孙策), Sun Gao was entrusted with tactical commands and garrisoned as the Commander of Wucheng (乌程督). In 200 AD, following the sudden assassination of Sun Ce, the fledgling regime of Jiangdong was thrown into severe jeopardy. Sun Quan was only eighteen years old, and external enemies encircled the territory. Viewing the moment of vulnerability, Sun Gao mobilized his garrison troops and prepared to advance on Kuaiji Commandery to seize control of the regional administration. However, the scholar-officer Yu Fan (虞翻, Ngu Phiên), then defending Kuaiji, sternly warned Sun Gao from the battlements, stating that the civil and military leadership of Kuaiji was united in loyalty to Sun Quan and would fight to the death. Realizing that internecine warfare would destroy the foundations of the Sun family’s conquests, Sun Gao heeded Yu Fan’s counsel and peacefully withdrew his army back to Wucheng.

Although Sun Gao did not ascend to the highest ranks of the court during Sun Quan’s reign, his branch of the family produced the most influential regents of late Eastern Wu: his son Sun Gong fathered Grand General and Regent Sun Jun (孙峻), and his son Sun Zhao fathered Grand General and Regent Sun Chen (孙綝), both of whom held total dictatorial power over the empire in the 250s AD.
