There was a commanding view from the entire camp, which occupied a ridge of hills; and the minds of all the soldiers anxiously awaited the issue of the battle. The Gauls had scattered archers and light-armed infantry here and there, among their cavalry, to give relief to their retreating troops, and sustain the impetuosity of our cavalry." - Julius Caesar, De Bello Gallico The Roman Republic’s development from a city state into a world power that controlled large swathes of modern Italy, Gaul and Spain, as well as other parts of Europe is seen by many as being the direct result of Roman fear of the “Celtic Threat.” The sacking of Rome by the Gauls in 386 BCE became indelibly imprinted into the Roman psyche, and with this fear came a desire to put as much distance as possible between the city of Rome and any potential enemy. The result was the gradual acquisition of buffer zones that became provinces of an empire that grew without any particular thought out or deliberate strategy of expansion.
