Cassivellaunus

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.
