The Battle of Alesia or Siege of Alesia (September 52 BC) was the climactic military engagement of the Gallic Wars, fought around the Gallic oppidum (fortified settlement) of Alesia in modern France, a major centre of the Mandubii tribe. It was fought by the Roman army of Julius Caesar against a confederation of Gallic tribes united under the leadership of Vercingetorix of the Arverni. It was the last major engagement between Gauls and Romans, and is considered one of Caesar's greatest military achievements and a classic example of siege warfare and investment; the Roman army built dual lines of fortifications—an inner wall to keep the besieged Gauls in, and an outer wall to keep the Gallic relief force out. The Battle of Alesia marked the end of Gallic independence in the modern day territory of France and Belgium. Archeological and historical research confirms that the battle site was most probably atop Mont Auxois, above modern Alise-Sainte-Reine in France. The event is described by Caesar himself in his Commentarii de Bello Gallico as well as several later ancient authors (namely Plutarch and Cassius Dio).
