In 49 BC the Roman Republic collapsed once more into bloody civil war. At the heart of this war lay the two greatest living Roman commanders, and former allies, Pompey the Great and Julius Caesar, each having built their own factions within the Roman oligarchy and refusing to compromise. The subsequent civil war would be fought for control of the Republic with each man determined to restore peace and stability to Rome, under their leadership. Yet despite this clash it was eighteen months before the two men met in Battle at Dyrrhachium in Albania.

Gareth Sampson outlines the strategic background, describing the early campaigns of the civil war and the factions of Caesar and Pompey that fought for control of the vast resources of the Republic. The Battle of Dyrrhachium itself is analysed to determine the strengths and weakness of both armies and their various commanders as well as the tactics used in the phases of the battle which culminated in victory for Pompey. Focus is also given to the aftermath of the battle that saw Caesar defeated and Pompey in the ascendancy.
