One of the greatest military commanders in history, Julius Caesar's most famous victory - the conquest of Gaul - was to him little more than a stepping stone to power. An audacious and decisive general, his victories over the Gauls allowed him to challenge for the political leadership of Rome. Leading a single legion across the Rubicon in 49 BC, Caesar launched a civil war which would end the Roman Republic and usher in the Roman Empire, with Caesar at its helm. This examination of the great general's life covers his great victories and few defeats, looking at the factors which lay behind his military genius.

Having survived the perils of a journey across half the world, Romulus and Tarquinius are press-ganged into the legions, which are under imminent threat of annihilation by the Egyptians. Meanwhile in Rome, Romulus' twin sister Fabiola lives in fear for her life, loved by Brutus, but wooed by Marcus Antonius, his deadly enemy. Soon after, Romulus fights at Zela, the vicious battle where Caesar famously said, 'Veni, vidi, vici'. Tarquinius, separated from Romulus in the chaos of war, hides in Alexandria, searching for guidance. But mortal danger awaits them both. From the battlefields of Asia Minor and North Africa, to the lawless streets of Rome and the gladiator arena, they face death daily, until on the Ides of March, the twins are reunited and must decide either to back or to betray Caesar on his day of destiny.
