Battle of Herdonia (210 BC)

There is a controversy among modern historians arising from the narrative of Titus Livius, the major source of this event, who describes two battles taking place in the span of two years (in 212 BC and 210 BC) at the same place (Herdonia) between Hannibal and Roman commanders with similar names (Gn. Fulvius Flaccus and Gn. Fulvius Centumalus). Some state that there was just one battle in fact, but there is no general agreement on this issue.[1]

Following his incursion into southern Italy in 217 BC, Hannibal defeated the Roman forces in the battle of Cannae (216 BC). This victory brought him a host of new allies from Campania, Samnium, Apulia, Lucania, Bruttium, and Magna Graecia, who revolted from Rome enticed by his narrative of Roman oppression. One of these allies was the city of Herdonia in northern Apulia. It was the site of a general engagement between Hannibal and the Romans already in 212 BC (see the first battle of Herdonia), because despite the severe defeats on the battlefield, Rome still managed to preserve intact the core of its system of alliances in Italy and continued to mount a slow but steady counter-offensive.[2]

The first battle of Herdonia ended with the almost total annihilation of the troops led by the praetor Gnaeus Fulvius Flaccus.[3] However Flaccus' army was just a fraction of the forces fielded by Rome. The siege of Capua, which had begun years before, ended in 211 BC with the fall of the largest city that had taken the side of Hannibal after Cannae. The Carthaginian's inability to defend Capua reversed the mood among many of his allies and Hannibal's position began to weaken.[4]

The Roman advance in southern Italy continued in 210 BC. Two armies stood against Hannibal in Apulia. One was under the consul Marcus Claudius Marcellus. The proconsul Gnaeus Fulvius Centumalus commanded the other. Their overall strength was four Roman legions, plus an approximately equal allied contingent.[5] Since they operated not far from each other, Hannibal did not dare to challenge them. This allowed Marcellus to capture the city of Salapia (see the map), that was betrayed to him by a fraction of its citizens, and to destroy the Carthaginian garrison.[6]

Following this setback, Hannibal retreated and a rumour was spread that he was going away to Bruttium. Upon learning this, Marcellus moved to Samnium and reduced two more towns that served as Carthaginian bases in this region.[7] Meanwhile, Hannibal returned to northern Apulia with forced marches and managed to catch Centumalus off-guard when the latter was besieging Herdonia. Despite the Carthaginian numerical superiority the proconsul did not decline the battle. He arranged his army in two battle lines and clashed with the Carthaginian infantry. Hannibal waited until the Romans and their allies were fully engaged and sent his Numidian cavalry to surround them. Part of the Numidians attacked the Roman camp which was insufficiently protected. The others fell upon the rear legion and dispersed it. The same happened to the Romans fighting in the front line. Centumalus, eleven (out of twelve) military tribunes, and 7,000–13,000[8] soldiers were slain. The rest were scattered and some escaped to Marcellus in Samnium.[5][7]

The victory did not bring strategic advantages to Hannibal. Judging that in the long run he could not retain Herdonia, the Carthaginian general decided to resettle its population in Metapontum and Thurii to the south and destroy the city itself.[9] Before that he set an example to other eventual traitors by executing some of the distinguished citizens who had conspired to betray Herdonia to Centumalus.[7] For the rest of the summer he was forced to fight off the second Roman army. The next battle with Marcellus at Numistro was inconclusive[10] and Hannibal was unable to regain the positions lost at the beginning of the campaign.

The second defeat at Herdonia did not make the Roman Senate change its warlike stance. Once again, as in the aftermath of Cannae, the senators resorted to punitive actions against the remnants of the defeated army. 4,344 men were rounded up and sent to Sicily where they joined the survivors of Cannae and were sentenced to serve on the island until the end of the war.[11] This had undesired repercussions. The deportation of the soldiers, most of whom were of Latin origin, caused considerable discontent among the Latin colonies which had already been drained by ten years of continuous warfare on Italian soil. Amidst great want of additional manpower and financial resources twelve out of thirty colonies refused to send any more levies and money to Rome. This crisis continued for five years and put severe strain on the Roman war effort.[4][12]
