The Siege and Battle of Alesia meant the end of the Gallic Wars, and took place from September to October 52 BC. It befell around the Gallic fortified settlement of Alesia, “capital” of the Mandubii tribe. It confronted the Roman army of Julius Caesar against an alliance of Gallic tribes, united under the leadership of Vercingetorix of the Averni. In history, it is considered one of Caesar´s most important military victories, as well as a classic example of siege warfare. This battle marked the end of the Gallic independence of France and Belgium.
The day after the battle, Caesar ordered the Gauls to surrender their weapons and deliver their chieftains. The chieftains were brought before him and Vercingetorix was surrendered.
For Caesar, Alesia was an enormous personal success, both militarily and politically. The senate declared 20 days of thanksgiving for this victory, but refused Caesar the honour of celebrating a triumphal parade, the peak of any general’s career. Political tension increased, and two years later, in 49 BC, Caesar crossed the Rubicon, which precipitated the Roman Civil War of 49–45 BC, which he won.
