On this hill, which I have just mentioned, stretching in a transverse direction,XLIX. In a tranverse direction] Transverso itinere. It lay on the flank of the Romans as they marched toward the river, in dextero latere. c. 49, fin Jugurtha took post with his line drawn out to a great length. The command of the elephants, and of part of the infantry, he committed to Bomilcar, and gave him instructions how to act. He himself, with the whole of the cavalry and the choicest of the foot, took his station nearer to the range of mountains. Then, riding round among the several squadrons and battalions, he exhorted and conjured them to call to mind their former prowess and triumphs, and to defend themselves and their country from Roman rapacity; saying that they would have to engage with those whom they had already conquered and sent under the yoke, and that, though their commander was changed, there was no alteration in their spirit. He added, that he had provided for his men every thing becoming a general; that he had chosen the higher ground, where they, being well acquainted with the country,Well acquainted with the country] Prudentes. "Periti loci et regionis"Cortius. Or it may mean knowing what they were to do, while the enemy would be imperiti, surprised and perplexed. would contend with adversaries ignorant of it; nor would they engage, inferior in numbers and skill, with a larger or more experienced force; and that they should, therefore, be ready, when the signal should be given, to fall vigorously on the Romans, as that day would either crownWould crown] Confirmaturum. Would establish, settle, put the last hand to them. all their labors and victories, or be a prelude to the most grievous calamities. He also addressed himself, individually, to any one whom he had rewarded with money or honors for military desert, reminding him of his favors, and pointing him out as an example to the rest; and finally he excited all his men, some in one way and some in another, by threats or entreaties, according to the different dispositions of each.

Metellus, who was still ignorant of the enemy's position, was now seenWas seen] Conspicitur. This is the reading adopted by Cortius, Müller and Allen as being that of all the manuscripts. Havercamp, Kritzius, and Dietsch admitted into their texts, on the sole authority of Donatus ad Ter. Eun. ii. 3, conspicatur, i.e. (Metellus) catches sight of the enemy. The latter reading, perhaps, makes a better connection. descending the mountain with his army. He was at first doubtful what the strange appearance before him indicated; for the Numidians, both cavalry and infantry, had taken post among the wood, not entirely concealing themselves, by reason of the lowness of the trees, yet rendering it uncertainRendering it uncertain] Incerti. Presenting such an appearance that a spectator could not be certain what they were. what they were, as both themselves and their standards were screened as well by the nature of the ground as by artifice; but soon perceiving that there were men in ambush, he halted awhile, and, having altered the arrangement of his troops, he drew up those in the right wing, which was nearest to the enemy, in three lines ;He drew up these in the right wing—in three lines] In dextero latere-triplicibus subsidiis aciem instruxit. In the other passages in which Sallust has the word subsidia (Cat. c. 59) he uses it for the lines behind the front. Thus he says of Catiline, Octo cohortes in fronte constituit; reliqua signa in subsidiis arctiùs collocat; and of Petreius, Cohortes veteranas—in fronte; post eas reliquum exercitum in subsidiis locat. But whether he uses the word in the same sense here: whether we might, as Cortius thinks (whom Gerlach and Dietsch follow), call the division of Metellus's troops quadruple instead of triple, or whether he arranged them, as De Brosses and others suppose, in the usual disposition of Hastati, Principes, and Triarii, who shall place beyond dispute? The probability, however, if Sallust is consistent with himself in his use of the word, lies with Cortius. Gerlach refers to Cæsar, De Bell, Civ., iii. 89: " Celeriter ex tertiâ acie singulas cohortes detraxit, atque ex his quartam instituit; but this does not illustrate Sallust's use of the word subsidia: Cæsar forms a fourth acies; Metellus draws up one acies "triplicibus subsidia." he distributed the slingers and archers among the infantry, posted all the cavalry on the flanks, and having made a brief address, such as time permitted, to his men, he led them down, with the front changed into a flank,With the front changed into a flank] Transversis principiis. He made the whole army wheel to the left, so that what was their front line, or principia, as they faced the enemy on the hill, became their flank as they marched from the mountain toward the river. toward the plain.

But when he observed that the Numidians remained quiet, and did not offer to descend from the hill, he became apprehensive that his army, from the season of the year and the scarcity of water, might be overcome with thirst, and therefore sent Rutilius, one of his lieutenant-generals, with the light-armed cohorts and a detachment of cavalry, toward the river, to secure ground for an encampment, expecting that the enemy, by frequent charges and attacks on his flank, would endeavor to impede his march, and, as they despaired of success in arms, would try the effect of fatigue and thirst on his troops. He then continued to advance by degrees, as his circumstances and the ground permitted, in the same order in which he had descended from the range of mountains. He assigned Marius his post behind the front line,L. Behind the front line] Post principia. The principia are the same as those mentioned in the preceding note, that is, the front line when the army faced that of Jugurtha on the hill, but which presented its flank to the enemy when the army was on its march. So that Marius commanded in the center ("in medio agmine," says Dietsch), while Metellus took the lead with the cavalry of the left wing. See the following note. and took on himself the command of the cavalry on the left wing, which, on the march, had become the van.Cavalry on the left wing-which, on the march, had become the van] Sinistrœ ulœ equitibus—qui in agmine principes facti erant. When Metellus halted (c. 49, fin.), and drew up his troops fronting the hill on which Jugurtha was posted, he placed all his cavalry in the wings; consequently, when the army wheeled to the left, and marched forward, the cavalry of the left wing became the van.

When Jugurtha perceived that the rear of the Roman army had passed his first line, he took possession of that part of the mountain from which Metellus had descended, with a body of about two thousand infantry, that it might not serve the enemy, if they were driven back, as a place of retreat, and afterward as a post of defense; and then, ordering the signal to be given, suddenly commenced his attack. Some of his Numidians made havoc in the rear of the Romans, while others assailed them on the right and left wings; they all advanced and charged furiously, and every where threw the consul's troops into confusion. Even those of our men who made the stoutest resistance, were baffled by the enemy's versatile method of fighting, and wounded from a distance, without having the power of wounding in return, or of coming to close combat; for the Numidian cavalry, as they had been previously instructed by Jugurtha, retreated whenever a troop of Romans attempted to pursue them, but did not keep in a body, or collect themselves into one place, but dispersed as widely as possible. Thus, being superior in numbers, if they could not deter the Romans from pursuing, they surrounded them, when disordered, on the rear or flank, or, if the hill seemed more convenient for retreat than the plain, the Numidian horses, being accustomed to the brushwood, easily made their way among it, while the difficulty of the ascent, and want of acquaintance with the ground, impeded those of the Romans.
