This takes place in Gergovia in the year 52 BC.
Gergovia, a city in ancient Gaul, located 5 km from present-day Clermont-Ferrand.

A young blond man, a farmer, and moreover from Auvergne, who had a strong taste for
independence, meets Julius Caesar. The latter, a great warrior, greedy for possessions, had just invaded Auvergne at the head of six legions.

The mountain looked terrifying, with Gallic armies occupying its entire height. At its foot lay Caesar’s camp. Caesar suffered a bloody defeat that prevented him from remaining any longer in front of Gergovia. He engaged in a few more cavalry skirmishes to spare the pride of his Roman soldiers, then broke camp and crossed back over the Allier River. This was Vercingetorix’s Auvergne War. The land of Gergovia witnessed his victory and offered its milk, honey, and wine.
