The progress of the siege and the various battles is illustrated with some very helpful diagrams. A short walk from the museum leads to an area where examples of the siege- works and Roman encampments have been constructed (pl.6).

We left the museum with a much clearer idea of this crucial battle in the and the way in which it was fought. A short drive took us up through the modern village of Alise-Ste-Reine to the car park by the small museum at the entrance to the site of the Gallo-Roman settlement. There is an excellent three-dimensional model there to illustrate the siege (pl.7).

The Aftermath.

Last of all Although the defeat of Vercingetorix and he brought up fresh reinforcements himself. the capture of Alesia were significant in Vercingetorix was beaten back. Caesar bringing the campaigns in Gaul to an end, then hurried to support Labienus with four campaigning continued through 51 and 50 cohorts (about 2,000 men) from the next B.C. Eventually (perhaps Puy fort and some cavalry. He sent the rest of d’Issolu in Lot) was taken.

Thirdly, Caesar’s recruitment of cavalry, especially German cavalry, was vital to his success, especially in the events of 52 B.C. Fourthly, there was Caesar’s Balsdon, J.P.V.D. (1967).

So often in the Gallic Wars he stresses how he has chosen a suitable (idoneus) place for a battle or a camp. He was in a foreign country with difficult terrain and substantial rivers. He was heavily outnumbered, but therein lies the reason why Vercingetorix in particular and the Gauls as a whole lost in the end. They lacked unity, even at the end. They also lacked good logistical support compared to the Romans, who were generally well supplied with food and resources. We only have Caesar’s word for it, but, if Vercingetorix had 80,000 men (7.71) and the Gauls 250,000 (7.76) (their council had hoped for 320,000 (7.75)), they outnumbered Caesar’s ten legions by about six to one. At Alesia he had prepared as well as he possibly could to counter such odds and to give his men a fighting chance. And fight they did, with their own commander-in-chief joining them in the thick of it at the point when the battle was in the balance. Caesar was a military genius supported by one of the most efficient fighting machines in ancient history.

51 ERRATUM: This is a correction to the text at the end of p. 44 and the start of p. 45, from Peter Mountford’s article:

While Caesar was away from Transalpine Gaul during the winter of 53/52 BC, the Carnutes killed all the Roman citizens in Cenabum (Orleans) (7.3) and a Gallic revolt led by the Arvernian Vercingetorix began to spread (7.4-7). Caesar’s response was swift and typical of the way in which he responded to emergencies. He forced a way through the snow-covered Cevennes (Massif Central) with his troops (7.8) much to the amazement of the enemy who thought that such access was impossible. He gathered his forces at Vienne from where he launched successful attacks on Vellaunodunum (Beaune?) and Cenabum, the latter of which he burnt to the ground (7.9-11). These successes forced Vercingetorix to abandon the siege of Gorgobina (Charlieu sur Loire) and to march to meet Caesar near Noviodunum (Nevers). Caesar’s cavalry put the Gallic cavalry to flight and Vercingetorix could not prevent Caesar from capturing Noviodunum (7.12-13). Caesar then turned his attention to Avaricum (Bourges) which he besieged and captured in spite of difficulties caused by food shortages and the presence of Vercingetorix and his forces (7.14-28). Vercingetorix blamed the Roman success on their knowledge of siege works, which were unknown to the Gauls. He pointed out that he had advised against the defence of Avaricum. The remaining Gauls appreciated this and stayed loyal to their commander, who, in turn, promised to try to unify all of Gaul in opposition to Caesar (7.29-31). Caesar was forced to intervene in an internal leadership problem among the Aedui, one of the Romans’ Gallic allies. He then sent Labienus with four legions north to deal with the Senones and Parisii, while he himself marched south with six legions towards Gergovia (Clermont-Ferrand), the main town of the Arverni (7.32-4).
