With unimpaired courage and increased resentment the Numantines resumed the struggle; Laenas fought against them unsuccessfully, nor was his successor Gaius Hostilius Mancinus more fortunate (617).
But the catastrophe was brought about not so much by the arms of the Numantines, as by the lax and wretched military discipline of the Roman generals and by - what was its natural consequence - the annually-increasing dissoluteness, insubordination, and cowardice of the Roman soldiers. The mere rumour, which moreover was false, that the Cantabri and Vaccaei were advancing to the relief of Numantia, induced the Roman army to evacuate the camp by night without orders, and to seek shelter in the entrenchments constructed sixteen years before by Nobilior[5]. The Numantines, informed of their sudden departure, hotly pursued the fugitive army, and surrounded it: there remained to it no choice save to fight its way with sword in hand through the enemy, or to conclude peace on the terms laid down by the Numantines. Although the consul was personally a man of honour, he was weak and little known. Tiberius Gracchus, who served in the army as quaestor, had more influence with the Celtiberians from the hereditary respect in which he was held on account of his father who had so wisely organized the province of the Ebro, and induced the Numantines to be content with an equitable treaty of peace sworn to by all the staff-officers. But the senate not only recalled the general immediately, but after long deliberation caused a proposal to be submitted to the burgesses that the convention should be treated as they had formerly treated that of Caudium, in other words, that they should refuse to ratify it and should devolve the responsibility for it on those by whom it had been concluded. By right this category ought to have included all the officers who had sworn to the treaty; but Gracchus and the others were saved by their connections. Mancinus alone, who did not belong to the circles of the highest aristocracy, was destined to pay the penalty for his own and others' guilt. Stripped of his insignia, the Roman consular was conducted to the enemy's outposts, and, when the Numantines refused to receive him that they might not on their part acknowledge the treaty as null, the late commander-in-chief stood in his shirt and with his hands tied behind his back for a whole day before the gates of Numantia, a pitiful spectacle to friend and foe. Yet the bitter lesson seemed utterly lost on the successor of Mancinus, his colleague in the consulship, Marcus Aemilius Lepidus. While the discussions as to the treaty with Mancinus were pending in Rome, he attacked the free people of the Vaccaei under frivolous pretexts just as Lucullus had done sixteen years before, and began in concert with the general of the Further province to besiege Pallantia (618). A decree of the senate enjoined him to desist from the war; nevertheless, under the pretext that the circumstances had meanwhile changed, he continued the siege. In doing so he showed himself as bad a soldier as he was a bad citizen. After lying so long before the large and strong city that his supplies in that rugged and hostile country failed, he was obliged to leave behind all the sick and wounded and to undertake a retreat, in which the pursuing Pallantines destroyed half of his soldiers, and, if they had not broken off the pursuit too early, would probably have utterly annihilated the Roman army, which was already in full course of dissolution. For this conduct a fine was imposed on the high-born general at his return. His successors Lucius Furius Philus (618) and Gaius Calpurnius Piso (619) had again to wage war against the Numantines; and, inasmuch as they did nothing at all, they fortunately came home without defeat.
Even the Roman government began at length to perceive that matters could no longer continue on this footing; they resolved to entrust the subjugation of the small Spanish country-town, as an extraordinary measure, to the first general of Rome, Scipio Aemilianus. The pecuniary means for carrying on the war were indeed doled out to him with preposterous parsimony, and the permission to levy soldiers, which he asked, was even directly refused - a result towards which coterie-intrigues and the fear of being burdensome to the sovereign people may have co-operated. But a great number of friends and clients voluntarily accompanied him; among them was his brother Maximus Aemilianus, whosome years before had commanded with distinction against Viriathus. Supported by this trusty band, which was formed into a guard for the general, Scipio began to reorganize the deeply disordered army (620). First of all, the camp-followers had to take their departure - there were found as many as 2000 courtesans, and an endless number of soothsayers and priests of all sorts - and, if the soldier was not available for fighting, he had at least to work in the trenches and to march. During the first summer the general avoided any conflict with the Numantines; he contented himself with destroying the stores in the surrounding country, and with chastising the Vaccaei who sold corn to the Numantines, and compelling them to acknowledge the supremacy of Rome. It was only towards winter that Scipio drew together his army round Numantia. Besides the Numidian contingent of horsemen, infantry, and twelve elephants led by the prince Jugurtha, and the numerous Spanish contingents, there were four legions, in all a force of 60,000 men investing a city whose citizens capable of bearing arms did not exceed 8000 at the most.
