Arbogast vs Zhuge Dan

Arbogast, a Frankish general, was appointed Magister Militum (Master of Soldiers) in the Western Roman Empire. He effectively controlled the army and became the power behind the throne of the young Emperor Valentinian II.

After a series of conflicts with Valentinian II, Arbogast was implicated in the emperor's death, which was officially ruled a suicide. Arbogast then elevated Eugenius, a Roman rhetorician, as a puppet emperor.

Arbogast and his puppet emperor Eugenius were defeated by the Eastern Roman Emperor Theodosius I at the Battle of the Frigidus. Arbogast committed suicide after the battle, ending his rebellion.

Zhuge Dan commanded Wei forces at Dongxing against Wu. He led a premature assault on Wu fortifications, falling into an ambush. Wei forces were routed, suffering heavy losses. This defeat damaged his reputation and contributed to his later rebellion.

Zhuge Dan was appointed Inspector of Yang Province, giving him control over Wei's southeastern territories. This position provided him with military resources and autonomy. He used this power to prepare for his eventual rebellion against the Sima clan.

Zhuge Dan rebelled against Sima Zhao's regency, declaring loyalty to Wei. He allied with Wu forces and fortified Shouchun. Sima Zhao besieged the city for months. The rebellion failed when Wu reinforcements were defeated and Shouchun fell, leading to Zhuge Dan's execution.
