Commius vs Zhang Fei

Julius Caesar appointed Commius as king of the Atrebates after the Roman conquest of their territory. Commius became a loyal Roman ally, providing cavalry and support for Caesar's campaigns in Gaul and Britain.

Caesar sent Commius to Britain as an envoy to negotiate with British tribes before the first Roman invasion. Commius was briefly imprisoned by the Britons but later released, providing Caesar with intelligence about British resistance.

Commius fought at the Battle of Alesia, where Vercingetorix's forces were besieged by Caesar. After the Gallic defeat, Commius escaped and continued resistance against Roman rule in northern Gaul.

Commius joined Vercingetorix's Gallic rebellion against Rome, abandoning his alliance with Caesar. He led Atrebate forces in the uprising and became a key leader in the resistance.

After continued guerrilla warfare against Roman forces, Commius fled to Britain with his followers. He established a new kingdom among the British Atrebates, escaping Roman pursuit and maintaining his independence.

After Cao Cao's cavalry caught up with Liu Bei's fleeing army at Changban, Zhang Fei held the bridge with only 20 horsemen. He shouted a challenge to the enemy, and fearing an ambush, Cao Cao's forces did not advance, allowing Liu Bei to escape.

During Liu Bei's invasion of Yi Province, Zhang Fei captured the enemy general Yan Yan. Impressed by Yan Yan's defiance, Zhang Fei released him and treated him as an honored guest, a rare act of mercy that helped win over local support.

While preparing for Liu Bei's campaign against Wu, Zhang Fei was murdered in his sleep by his own subordinates, Fan Jiang and Zhang Da. They cut off his head and delivered it to Sun Quan. His death was a severe blow to Shu Han.
