The Battle of Alesia took place in 52 BC during the Gallic Wars, where the Roman general Julius Caesar faced off against the Gallic leader Vercingetorix. The battle occurred at the fortified hilltop city of Alesia, where Vercingetorix and his troops were besieged by the Romans. Caesar's forces built a series of fortifications to encircle the city, cutting off supplies and reinforcements. As the siege continued, Vercingetorix called for help from other Gallic tribes. A massive relief force attempted to break through the Roman lines, leading to intense fighting. Ultimately, Caesar's strategic brilliance led to a decisive Roman victory, solidifying Roman control over Gaul.
