The response of the Romans was hampered by the absence of the Roman legions, which were already engaged in fighting a revolt in Spain and the Third Mithridatic War. Furthermore, the Romans considered the rebellion more of a policing matter than a war. Rome dispatched militia under the command of praetor Gaius Claudius Glaber, who besieged Spartacus and his camp on Mount Vesuvius, hoping that starvation would force Spartacus to surrender. They were surprised when Spartacus, who had made ropes from vines, climbed down the cliff side of the volcano with his men and attacked the unfortified Roman camp in the rear, killing most of them.
