During this period the celerity of his movements had been such that his little host appeared to be almost ubiquitous, and men knew not where to look for his descent, or how to anticipate the blow, which he evidently had it in contemplation to deliver. In the meantime, he had given such of his adherents as fled from Rome immediately on the execution of the conspirators, an opportunity to join him, and many had in fact done so with their clients, and bands of gladiators. The disaffected of the open country had all united themselves to him; and having commenced operations with a force not exceeding two thousand men, he was now at the head of six times that number, whom he had formed into two complete legions, and disciplined them with equal assiduity and success. Now, however, the time had arrived when it was for his advantage no longer to avoid an encounter with the troops of the commonwealth; for having gained all that he proposed to himself by his dilatory movements and Fabian policy, time namely for the concentration of his adherents, and opportunity to discipline his men, he now began to suffer from the inconveniences of the system. Unsupplied with magazines, or any regular supply of provisions, his army like a flight of locusts had stripped the country bare at every halting place, and that wild hill country had few resources, even when shorn by the licentious band of his desperadoes, upon which to support an army. The consequence, therefore, of his incessant hurrying to and fro, was that the valleys of the mountain chain which he had made the theatre of his campaign, were now utterly exhausted; that his beasts of burden were broken down and foundered; and that the line of his march might be traced by the carcasses of mules and horses which had given out by the wayside, and by the flights of carrion birds which hovered in clouds about his rear, prescient of the coming carnage. His first attempt was to elude Metellus Celer, who had marched down from the Picene district on the Adriatic sea, with great rapidity, and taken post at the foot of the mountains, on the head waters of the streams which flow down into the great plain of the Po. In this attempt he had been frustrated by the ability of the officer who was opposed to him, who had raised no less than three legions fully equipped for war.
