*Spartacus.* While Pompey was fighting Sertorius in Spain and Lucullus was pursuing Mithradates in Bithynia a serious slave war arose in Italy. It began in 73 B. C. with the revolt of a band of gladiators from a training school in Capua under the leadership of the Thracian Spartacus and the Gauls, Crixus and Onemaus. Taking refuge on the slopes of Vesuvius they rapidly recruited large numbers of runaway slaves. They defeated the armies of two Roman praetors and overran Campania, Lucania, and all southern Italy. By the end of the year 73 B. C. their number had grown to 70,000. In the next year they divided their forces; the Gauls and Germans followed Crixus, the Thracians Spartacus. The two consuls took the field against them; Crixus and his horde were defeated in Apulia. Spartacus marched north, intending to make his way through the Alps to Thrace. The consuls pursued him, and he defeated them one after the other. Thereupon his followers refused to leave Italy and turned southwards, plundering as they went. Again Spartacus defeated the consuls but dared not attack Rome and retired to South Italy. *Crassus in command, 71 B. C.* In 71 B. C. the consuls displayed no enthusiasm to undertake the command against Spartacus, and so the Senate appointed as extraordinary commander the praetor Marcus Licinius Crassus, one of Sulla’s veteran officers, who volunteered his services. After restoring discipline among his troops, Crassus succeeded in penning up Spartacus in the peninsula of Bruttium. Spartacus hired some Cilician pirates to transport him to Sicily, but, after receiving their price, they abandoned him to his fate. He succeeded in breaking through Crassus’ lines, but his forces divided into two detachments, each of which was caught and beaten. Spartacus fell in battle; while 6000 of his following were taken and crucified. Crassus had bent all his energies to bring the revolt to a close before the arrival of Pompey, who was on his way from Spain. This he might fairly claim to have accomplished although a body of 5000 slaves who had escaped to North Italy were met by Pompey and annihilated. IV. THE CONSULATE OF POMPEY AND CRASSUS: 70 B. C.
