How Pompey the Great crushed a rebel army at the gates of Valentia
In 75 BC, the Roman Republic faced a persistent insurgency in Hispania led by the rogue general Quintus Sertorius. When Sertorius tasked his legates with holding the city of Valentia against the rising star Pompey the Great, the resulting clash became a brutal demonstration of Roman military superiority.
The conflict originated in the chaotic aftermath of the Roman civil wars that began in 88 BC. Quintus Sertorius, a former client of Gaius Marius, broke with the Sullan faction and established a power base in Hispania. By 80 BC, he had successfully expelled Sullan forces and employed sophisticated guerrilla tactics to exhaust the proconsul Quintus Caecilius Metellus Pius. The Senate, desperate to regain control, dispatched Pompey the Great in 76 BC to reinforce the Roman effort.
By 75 BC, Sertorius sought to expand his influence along the Iberian east coast. He tasked his legates, Marcus Perpenna Vento and Gaius Herennius, with defending Valentia against Pompey. The two commanders chose to engage Pompey in a confined space between the river Turia and the city walls. This decision proved catastrophic. Lacking a tactical advantage, the battle devolved into a raw test of endurance and strength where Pompey’s battle-hardened legions systematically dismantled the rebel forces.
The defeat was decisive. Pompey’s army massacred the opposition, resulting in approximately 10,000 casualties, including the death of Gaius Herennius. Following the slaughter, Valentia was sacked. While Sertorius attempted to salvage the situation by marching north to confront Pompey directly at the river Sucro, the loss at Valentia fundamentally shifted the momentum of the war. Despite a near-victory against Pompey at Sucro, Sertorius was eventually forced to abandon conventional engagements and return to the guerrilla warfare that defined his long, doomed resistance.
