Uxellodunum

Uxellodunum is an iron age hill fort, or oppidum, located above the river Dordogne near the modern-day French village of Vayrac in the Lot department. This stronghold lay within the lands of the Cadurci tribe. According to Aulus Hirtius in his addendum to Julius Caesar's Commentaries on the Gallic War, the last revolt against Rome's authority in Gaul occurred here, and was brutally punished.

The Commentaries on the Gallic War describe Uxellodunum as being strongly fortified by its natural position, with a river dividing the valley below that almost surrounded the steep craggy mountain on which the citadel was built. The name apparently means "high fort"; "dun" is a Celtic word for fort which is to be found in many place-names.

Description of siege

The main source of information about the siege in 51 BC is Book 8 of the Commentaries on the Gallic War. The siege is also mentioned briefly by the engineer Sextus Julius Frontinus in his book Stratagems.

The siege began after Lucterius, the leader of the Cadurci, and Drapes from the Senones, prepared Uxellodunum against a Roman assault. Caesar's commander in the area, the legate Gaius Caninius Rebilus, deployed his two legions. Informed by letter of the situation, Caesar decided to take personal charge of the siege.
