On 2 August 216 BC the Carthaginian General Hannibal won one of the most complete battlefield victories in history. Outnumbered nearly two to one, his heterogenous army of Africans, Spaniards and Celts not merely defeated, but virtually destroyed the Roman army opposing them. By the end of the day, nearly 50,000 Roman and Allied soldiers lay dead or were dying in an area of a few square kilometres, whilst between ten and twenty thousand more were prisoners. Less than 20% of one of the largest armies ever fielded by the Roman State survived to reform over the next few weeks. Cannae became the yardstick by which the Romans measured later catastrophes, but only one or two defeats in their history were ever judged to have been as bad. The scale of the losses at Cannae was unrivalled until the industrialized slaughter of the First World War.
