As Antonius[65] approached with his army, Catiline directed his march over the hills, encamping, at one time, in the direction of Rome, at another in that of Gaul. He gave the enemy no opportunity of fighting, yet hoped himself shortly to find one, if his accomplices at Rome should succeed in their objects. Slaves, meanwhile, of whom vast numbers had at first flocked to him, he continued to reject, not only as depending on the strength of the conspiracy, but as thinking it impolitic to appear to share the cause of citizens with runagates. When it was reported in his camp, however, that the conspiracy had been discovered at Rome, and that Lentulus, Cethegus, and the rest whom I have named had been put to death, most of those whom the hope of plunder or the love of change had led to join in the war fell away. The remainder Catiline conducted, over rugged mountains and by forced marches, into the neighborhood of Pistoria, with a view to escape covertly, by crossroads, into Gaul. But Quintus Metellus Celer, who, with a force of three legions, had, at that time, his station at Picenum, suspected that Catiline, from the difficulties of his position, would adopt precisely the course which we have just described. When, therefore, he had learned Catiline's route from some deserters, he immediately broke up his camp, and took his post at the very foot of the hills, at the point where Catiline's descent would be, in his hurried march into Gaul.[66] Nor was Antonius far distant, as he was pursuing, tho with a large army, yet through plainer ground, and with fewer hindrances, the enemy in retreat. Catiline, when he saw that he was surrounded by mountains and by hostile forces, that his schemes in the city had been unsuccessful, and that there was no hope either of escape or of succor, thinking it best, in such circumstances, to try the fortune of a battle, resolved upon engaging, as speedily as possible, with Antonius.... When he had spoken, he ordered, after a short delay, the signal for battle to be sounded, and led down his troops, in regular order, to the level ground. Having then sent away the horses of all the cavalry, in order to increase the men's courage by making their danger equal, he himself, on foot, drew up his troops suitably to their numbers and the nature of the ground. As a plain stretched between the mountains on the left, with a rugged rock on the right, he placed eight cohorts in front, and stationed the rest of his force, in close order, in the rear. From among these he removed all the ablest centurions, the veterans, and the stoutest of the common soldiers that were regularly armed into the foremost ranks. He ordered Caius Manlius to take the command on the right, and a certain officer of Faesulae on the left; while he himself, with his freedmen and the colonists, took his station by the eagle, which Caius Marius was said to have had in his army in the Cimbrian war.
