Julius Caesar, after a series of victories at Vellaunodunum, Genabum, and Noviodunum Biturigum, had arrived at Avaricum in the winter of 52 BC, intent on denying its grain and steel to the rebellious Gauls. Vercingetorix, aware that he had already been bested three times, decided to change tactics. Calling together a council of the tribes in rebellion against Rome, he convinced them to adopt Fabian strategy, never offering combat with Caesar's forces, and denying them supplies. All the towns within range of Caesar's foraging parties were destroyed, the land stripped bare, and all grain removed or burned, in a scorched earth tactic. However, Avaricum was spared this fate since the Bituriges argued the town was impossible to take, and Vercingetorix agreed to make the town an exception.
