The Andes, led by Dumnacus, played a significant role in the continuing war against Rome after the defeat of Vercingetorix at Alesia.

Dumnacus's efforts are recounted by Aulus Hirtius in his continuation of the Bellum Gallicum (Book 8), which covers the two years of the war after Caesar had declared his mission accomplished.

Dumnacus lay siege to Limonum (present-day Poitiers), an oppidum of the Pictones, and engaged without success the Roman relief army under the command of Gaius Caninius Rebilus.
