In 52 B.C. Rome's pre-eminent general, Gaius Julius Caesar found himself locked in a titanic struggle against the forces of King Vercingetorix of Gaul. Pacifying Gaul was paramount to Rome's security and Caesar needed a decisive victory to quell Gallic resistance once and for all. Having surrounded Vercingetorix and his army at Alesia, Caesar now found himself attacked in turn by a relief force which outnumbered him by 5 to 1. Using superior Roman tactics, discipline and military technology, he crushed the Gauls and forced Vercingetorix's surrender. This victory cemented Roman control of Western Europe for 400 years and elevated Caesar to mythic status as a battlefield commander. Narrated by actor Brian Cox.
