The praetor of Hispania Ulterior, Servius Sulpicius Galba commanded the Roman troops in Iberia c.150 BC, and at the same time Lucius Licinius Lucullus was appointed Governor of the Hispania Citerior and commander of an army. In the year 151 BC, Lucullus "being greedy of fame and needing money", made a peace treaty with the "Caucaei", of the Vaccaei tribe, after which he ordered his men to kill all the tribe's adult males, of which it is said only a few out of 30,000 escaped.
