How Rome Lost 70,000 Men in One Day and Still Won

How Rome conquered the Mediterranean after losing 50,000 men at Cannae is history's strangest comeback. In 216 BC Hannibal wiped out one in five Roman citizens in a single afternoon, yet 14 years later Rome dictated peace to Carthage. This film traces Polybius's answer — not tactics but the census — how Rome turned defeated Samnites, Latins and Gauls into Romans, fielded 700,000 men, and built an empire of 60 million that could absorb a Cannae every generation.
