In the summer of 208 BC, the Roman consulsMarcus Claudius Marcellus and Titus Quinctius Crispinus ordered a part of the Roman garrison of Tarentum to move up and assist in an offensive against the Carthaginian-allied town of Locri.[1] Hannibal received word from the people of Thurii of the Roman move and laid an ambush along the road from Tarentum with 3,000 infantry and 2,000 cavalry.[1]
Battle
The Carthaginian force was hidden at the foot of the hill of Petelia.[1] The Romans failed to conduct a reconnaissance and the Carthaginians achieved complete surprise.[1] They killed 2,000 Romans and captured 1,500.[1] The rest of the Roman force fled cross-country back to Tarentum.[1]
