Cassivellaunus vs Guanqiu Jian

Cassivellaunus led the British resistance against Julius Caesar's second invasion of Britain. He organized a coalition of British tribes and used guerrilla tactics, including chariot warfare, to harass Roman forces.

Cassivellaunus attempted to defend the River Thames crossing against Caesar's advancing legions. The Romans forced a crossing using a fortified bridge, and Cassivellaunus's forces were defeated, forcing him to retreat inland.

Caesar besieged Cassivellaunus's hillfort, likely located near modern-day St. Albans. The stronghold was captured after a fierce assault, and Cassivellaunus was forced to negotiate a surrender.

Cassivellaunus surrendered to Caesar after the fall of his stronghold. He agreed to pay tribute and provide hostages, ending the British resistance. Caesar then withdrew from Britain, leaving Cassivellaunus in power as a client king.

Guanqiu Jian was appointed Inspector of Yu Province, a key regional post. He was known for his administrative competence and military experience. This position gave him the resources to later challenge the Sima clan's growing power.

Guanqiu Jian and Wen Qin rebelled against Sima Shi in Shouchun. They issued a manifesto condemning Sima's usurpation. Sima Shi led a campaign against them. Guanqiu Jian was killed in battle, and the rebellion was crushed, leading to his posthumous disgrace.
