 He had marched to join Hannibal in Campania in early 214 BC, but, near the River Calor, at Beneventum, his army was intercepted by the praetor Tiberius Gracchus and his legions of mostly freed slaves.In the ensuing combat, Hanno’s army of 17,000 foot (mostly Bruttians and Lucanians) and 1,200 horse was utterly routed, forcing Hanno to escape with only 2,000 soldiers, chiefly cavalry back to Bruttium.His situation improved when he destroyed a force of pro-Roman Lucanians in early 213 BC in Bruttium.
