Cao Hong vs Carausius

During Cao Cao's campaign against Zhang Xiu, Cao Cao was ambushed at Wancheng. Cao Hong provided his own horse to Cao Cao, allowing him to escape, and then fought a rearguard action to cover the retreat.

Cao Hong fought under Cao Cao at Guandu against Yuan Shao. He led cavalry units and participated in the burning of Yuan Shao's supply wagons at Wuchao, contributing to the decisive Wei victory.

Cao Hong led Wei forces against Liu Bei's invasion of Hanzhong. He initially defeated Wu Lan and other Shu generals but was later outmaneuvered by Liu Bei's tactics, contributing to the eventual loss of Hanzhong to Shu.

During the reign of Cao Rui, Cao Hong was accused of corruption and abuse of power. He was imprisoned, and his property was confiscated. He was later released but never regained his former influence.

Emperor Maximian appointed Carausius to command the Roman fleet in the English Channel, tasked with suppressing Frankish and Saxon pirates. Carausius, a Menapian, used this position to build a loyal naval force.

Accused of embezzling recovered treasure and facing execution, Carausius declared himself emperor in Britain. He secured control of the island and parts of Gaul, establishing a breakaway regime that lasted seven years.

Carausius was murdered by his finance minister Allectus, who then seized power in Britain. The assassination ended Carausius's rule and destabilized the breakaway regime, leading to its collapse three years later.
