In 152 BC, the consul Marcus Claudius Marcellus urged the Senate to conclude a peace with the Celtiberians. The Senate rejected this proposal, and instead sent one of the consuls of 151 BC, Lucius Licinius Lucullus, to Hispania to continue the war. However, there was a crisis of recruitment due to rumors of incessant battles and heavy Roman losses. Additionally, Marcellus appeared to be afraid of continuing the war; this led to panic. Young men avoided enrollment as soldiers through unverifiable excuses. Men eligible to be legates (legion commanders) or military tribunes (senior officers) did not volunteer.
