Celtic warfare
The "Gallic Wars" were a series of military campaigns waged by the Roman proconsul Julius Caesar against Gallic tribes, lasting from 58 BC to 51 BC. The Romans would also raid Britannia and Germania, but these expeditions never developed into full-scale invasions. The Gallic Wars culminated in the decisive Battle of Alesia in 52 BC, in which a complete Roman victory resulted in the expansion of the Roman Republic over the whole of Gaul. The wars paved the way for Caesar to become the sole ruler of the Roman Republic.
Alesia (city)
Alesia is best known for being the site of the decisive Battle of Alesia in 52 BC that marked the defeat of the Gauls under Vercingetorix by the Romans under Julius Caesar. Caesar described the battle in detail in his "" (Book VII, 69–90). The battle's outcome determined the fate of all of Gaul: in winning the battle, the Romans won both the Gallic Wars and dominion over Gaul.
