Gallic Wars
In 58 BC, the neighboring Helvetii had launched a military campaign into Aeduan territory as part of their designs to migrate to the lands of the Santones along the Bay of Biscay. The Aedui petitioned for Roman intervention due to their longstanding alliance and a force led by Julius Caesar would enter Gaul. Roman intervention would prove divisive for the local Gallic elite as some feared the Roman intervention would turn into an occupation and thought it better to submit to the rule of the Helvetii.
The anti-Roman faction would attempt to sabotage the war effort by delaying the provision of grain rations to Roman troops and giving intelligence to the Helvetii. After Caesar arranged a meeting with Liscus, Divitiacus, and the other Aeduan chiefs over the matter of the grain, Liscus would reveal the existence of the anti-Roman faction and explained his inability to act against them. After the meeting concluded, Caesar and Liscus remained behind to talk in private and Liscus would identify Dumnorix, one of the leaders of the Aeduan cavalry and brother of Divitiacus, as both the anti-Roman faction's leader and as responsible for ordering a sudden retreat of the Aeduan cavalry during a recent battle.
Though Dumnorix's collusion with the Helvetii was deemed treason, he would be spared due to Divitiacus's good relations with the Romans. Liscus is not mentioned again in Caesar's writings and his fate afterwards is unknown.
