The senate in the first place cancelled the second treaty of peace— to surrender to the enemy the commander who had concluded it, as was done some thirty years before, seemed according to the new ideas of the sanctity of treaties no longer necessary—and determined, this time in all earnest, to renew the war. The supreme command in Africa was entrusted, as was natural, to an aristocrat, but yet to one of the few men of quality who in a military and moral point of view were equal to the task. The choice fell on Quintus Metellus. He was, like the whole powerful family to which he belonged, in principle a rigid and unscrupulous aristocrat; as a magistrate, he, no doubt, reckoned it honourable to hire assassins for the good of the state and would presumably have ridiculed the act of Fabricius towards Pyrrhus as unpractical knight errantry, but he was an inflexible administrator accessible neither to fear nor to corruption, and a judicious and experienced warrior. In this respect he was so far free from the prejudices of his order that he selected as his lieutenants not men of rank, but the excellent officer Publius Rutilius Rufus, who was esteemed in military circles for his exemplary discipline and as the author of an altered and improved system of drill, and the brave Latin farmer’s son Gaius Marius, who had risen from the pike. Attended by these and other able officers, Metellus presented himself in the course of 645 as consul and commander-in-chief to the African army, which he found in such disorder that the generals had not hitherto ventured to lead it into the enemy’s territory and it was formidable to none save the unhappy inhabitants of the Roman province. It was sternly and speedily reorganized, and in the spring of 646.(12)
Metellus led it over the Numidian frontier. When Jugurtha perceived the altered state of things, he gave himself up as lost, and, before the struggle began, made earnest proposals for an accommodation, requesting ultimately nothing more than a guarantee for his life. Metellus, however, was resolved and perhaps even instructed not to terminate the war except with the unconditional subjugation and execution of the daring client-prince; which was in fact the only issue that could satisfy the Romans. Jugurtha since the victory over Albinus was regarded as the deliverer of Libya from the rule of the hated foreigners; unscrupulous and cunning as he was, and unwieldy as was the Roman government, he might at any time even after a peace rekindle the war in his native country; tranquillity would not be secured, and the removal of the African army would not be possible, until king Jugurtha should cease to exist. Officially Metellus gave evasive answers to the proposals of the king; secretly he instigated the envoys to deliver their master living or dead to the Romans. But, when the Roman general undertook to compete with the African in the field of assassination, he there met his master; Jugurtha saw through the plan, and, when he could not do otherwise, prepared for a desperate resistance.
