The consul's eagerness to gain a complete victory was thus increased; he exerted himself in every possible way, taking care, at the same time, to give the enemy no opportunity of attacking him to advantage. He remembered that envy is the concomitant of glory, and thus, the more renowned he became, the greater was his caution and circumspection. He never went out to plunder, after the sudden attack of Jugurtha, with his troops in scattered parties; when corn or forage was sought, a body of cohorts, with the whole of the cavalry, were stationed as a guard. He himself conducted part of the army, and Marius the rest. The country was wasted, however, more by fire than by spoliation. They had separate camps, not far from each other; whenever there was occasion for force, they formed a union; but, that desolation and terror might spread the further, they acted separately. Jugurtha, meanwhile, continued to follow them along the hills, watching for a favorable opportunity or situation for an attack. He destroyed the forage, and spoiled the water, which was scarce, wherever he found that the enemy were coming. He presented himself sometimes to Metellus, and sometimes to Marius; he would attack their rear upon a march, and instantly retreat to the hills; he would threaten sometimes one point, and sometimes another, neither giving battle nor allowing rest, but making it his great object to retard the progress of the enemy.
