Battle of Valentia (75 BC)
The Battle of Valentia was fought in 75 BC between a rebel army under the command of Marcus Perpenna Vento and a general called Gaius Herennius, both legates of the Roman rebel Quintus Sertorius, and a Roman Republican army under the command of the Roman general Gnaeus Pompeius Magnus. The battle was fought at Valentia in Spain and ended in a stunning victory for the Pompeian army.
Background
In 88 BC, Lucius Cornelius Sulla marched his legions on Rome, starting a period of civil wars. Quintus Sertorius, a client of Gaius Marius, joined his patron's faction and took up the sword against the Sullan faction. After the death of Lucius Cornelius Cinna and Gaius Marius, Sertorius lost faith with his factions leadership. In 82 BC, during the war against Sulla, he left Italy for his assigned province in Hispania. His faction lost the war in Italy right after his departure and in 81 BC Sulla sent Gaius Annius Luscus with several legions to take the Iberian provinces from Sertorius. After a brief resistance Sertorius and his men are expelled from Hispania. They end up in Mauretania in north-western Africa where they conquer the city of Tingis. Here the Lusitanians, a fierce Iberian tribe who were about to be invaded by a Sullan governor, approached him. They asked him to become their war leader in the fight against the Sullans.In 80 BC, Sertorius landed at the little fishing town of Baelo near the Pillars of Hercules and returned to Hispania. Soon after his landing he fought and defeated the Sullan general Lucius Fufidius at the Baetis river. After this, he defeated several Sullan armies and drove his opponents from Hispania. Threatened by Sertorius' success the Senate in Rome upgraded Hispania Ulterior to a proconsular province and sent the proconsul Quintus Caecilius Metellus Pius with a large army to fight him. Sertorius used guerrilla tactics so effectively he wore down Metellus to the point of exhaustion while his legate Lucius Hirtuleius defeated the governor of Hispania Citerior Marcus Domitius Calvinus.
In 76 BC, the government in Rome decided to send Pompey and an even larger army to help Metellus. In the same year Sertorius is joined by Marcus Perpenna, who brought him the remnants of the army of Marcus Aemilius Lepidus the rebel consul of 78 BC. Thus reinforced Sertorius decided to try and take the Iberian east coast. His first target was the city of Lauron where he outgeneraled Pompey and massacred a large part of his army.
