Italy was torn by the Servile War. This disinherited class had risen up anew, despite the bloody repression of the Sicilian insurrection from 620 to 623. It had acquired the knowledge of its strength chiefly from the circumstance that each party in the civil troubles had by turns granted its liberty to increase the number of its respective adherents. In 681, seventy gladiators, kept at Capua, revolted; their chief was Spartacus, formerly a soldier, made prisoner, then sold as a slave. In less than a year his band had so much increased that consular armies were needed to combat him, and, having gained a victory in Picenum, for a moment he had entertained the thought of marching upon Rome at the head of 40,000 men.[824] Nevertheless, forced to withdraw to the south of Italy, he contended against the Roman forces successfully for two years, when at last, in 683, Licinius Crassus, at the head of eight legions, conquered him in Apulia. Spartacus perished in the fight; the remainder of the army of slaves separated into four bodies, one of which, retiring towards Gaul, was easily dispersed by Pompey, who was returning from Spain. The 6,000 prisoners taken in the battle fought in Apulia were hanged all along the road from Capua to Rome. Occasions for making himself perfect in the art of war were not wanting to Cæsar; but we can understand his inaction, for Sylla’s partisans alone were at the heads of the armies; in Spain, Metellus and Pompey--the first the brother-in-law of the Dictator, the second formerly his best lieutenant; in Italy, Crassus, the enemy of Cæsar, equally devoted to the party of Sylla; in Asia, Lucullus, an old friend of the Dictator, who had dedicated his “_Memoirs_”[825] to him. Cæsar, then, found everywhere either a cause he would not defend, or a general under whom he would not serve. In Spain, however, Sertorius represented the party he would most willingly have embraced; but Cæsar had a horror of civil wars. Whilst faithful to his convictions, he seems, in the first years of his career, to have carefully avoided placing between him and his adversaries that eternal barrier which for ever separates the children of the same country, after blood has once been shed. He had it at heart to be able, in his exalted future, to appeal to a past pure from all violence, so that, instead of being the man of a party, he might rally round him all good citizens.
