Hispania Ulterior and was campaigning against a Lusitanian rebellion, conducted a joint pincer operation against Lusitania. According to Appian they gradually depopulated it. Appian described Galba as being even more greedy than Lucullus. He killed many Lusitanians by treachery. Lusitanian War and Viriathic War Lusitania was probably the area of the peninsula that resisted the Roman invasion for the longest time. Until the year 155 BC, the Lusitanian chief Punicus made raids into the part of Lusitania controlled by Rome, ending with the twenty-year peace made by the former praetor Sempronius Gracchus. Punicus obtained an important victory against the praetors Manilius and Calpurnius, inflicting 6,000 casualties. After the death of Punicus, Caesarus took charge of the fight against Rome, vanquishing the Roman troops again in 153 BC, revealing his banner in the battle, which triumphantly showed to the rest of the Iberian peoples how to display the vulnerability of Rome. At the time, the Vetones and Celtiberians had united in resistance, leaving the situation for Rome in this area of Hispania somewhat precarious. Lusitanians, Vetones and Celtiberians raided the Mediterranean coasts, while, to secure their position on the Peninsula, they deployed to North Africa. It was in this year that two new consuls arrived in Hispania, Quintus Fulvius Nobilior and Lucius Mummius. The urgency of restoring dominion over Hispania made the two consuls enter into battle within two and a half months. The Lusitanians sent to Africa were defeated at Okile (modern Arcila in Morocco) by Mummius, who forced them to accept a peace treaty. For his part, the consul Serbius Sulpicius Galba made a peace treaty with three of the Lusitanian tribes, and then, pretending to be a friend, killed the youth and sold the rest of the people to Gaul. Nobilior was replaced in the following year (152 BC) by Marcus Claudius Marcellus (consul 166 BC). He in turn was succeeded in 150 BC by Lucius Licinius Lucullus, who was distinguished by his cruelty and infamy. In 147 BC, a new Lusitanian leader named Viriathus rebelled against the Roman forces. He had fled from Serbius Sulpicius Galba three years earlier, and, reuniting the Lusitanian tribes again, Viriathus began a guerrilla war that fiercely struck the enemy without giving open battle. He commanded many campaigns and arrived with his troops at the Murcian coasts. His numerous victories and the humiliation he inflicted upon the Romans made him worthy of
