Caesar: Conqueror of Gaul (Line of Fire, 2002)

In 58 BC, Julius Caesar pushed north from Rome into unruly lands of the barbarians. Less than eight years later, the empire extended all the way to the Atlantic, and Roman Legions were making incursions into Britain. The key to Caesar's victory lay not in the superiority of the Roman war machine but in his mastery of strategy, tactics, discipline, and military engineering. According to Plutarch, Caesar's campaign resulted in 800 conquered cities, 300 subdued tribes, a million slaves, and 3-million dead on the battlefield--all this, not to mention becoming First Man in Rome.
