Sertorius

Besides this, Metellus was now getting on in years, and was somewhat inclined also, by this time, to an easy and luxurious mode of life after his many and great contests; whereas his opponent, Sertorius, was full of mature vigour, and had a body which was wonderfully constituted for strength, speed, and plain living.

For in excessive drinking he would not indulge even in his hours of ease, and he was wont to endure great toils, long marches, and continuous wakefulness, content within meagre and indifferent food; moreover, since he was always wandering about or hunting when he had leisure for it, he obtained an acquaintance with every way of escape for a fugitive, or of surrounding an enemy under pursuit, in places both accessible and inaccessible. The result was, therefore, that Metellus, by being kept from fighting, suffered all the harm which visits men who are defeated; while Sertorius, by flying, had the advantages of men who pursue.

For he would cut off his opponent’s supply of water and prevent his foraging; if the Romans advanced, he would get out of their way, and if they settled down in camp, he would harass them; if they besieged a place, he would come up and put them under siege in their turn by depriving them of supplies. At last the Roman soldiers were in despair, and when Sertorius challenged Metellus to single combat, they cried aloud and bade him fight, general with general, and Roman with Roman, and when he declined, they mocked at him.
