Background
As described on the Osprey Publishing website, “In 52 BC Caesar’s continued strategy of annihilation had engendered a spirit of desperation, which detonated into a revolt of Gallic tribes under the leadership of the charismatic young Arvernian noble Vercingetorix. Major engagements were fought at Noviodunum, Avaricum, and Gergovia, with the last action being the most serious reverse that Caesar faced in the whole of the Gallic War. However, Vercingetorix soon realized that he was unable to match the Romans in pitched battle. Taking advantage of the tribesmen’s superior knowledge of their home territory, Vercingetorix began a canny policy of small war and defensive maneuvers, which gravely hampered Caesar’s movements by cutting off his supplies. For Caesar it was to be a grim summertime – his whole Gallic enterprise faced disaster.
