He played an important role at the Siege of Gergovia.
During the siege of Gergovia, Litaviccus was given command over 10,000 men who were sent to aid Caesar.
During the march, however, Litavccus gave a speech to his soldiers where he claimed the Romans had killed the nobles of the Aedui, and that they had the same planned for the rest of the tribe.
This convinced the soldiers to desert the Romans and instead join Vercingetorix.
Though the army of Litaviccus was very small compared to the Legions of Caesar, Caesar was nonetheless forced to remove a part of his soldiers at Gergovia to deal with Litaviccus.
