And when now all the cities on this side of the river Ebro also united their forces together under his command, his army grew great, for they flocked together and flowed in upon him from all quarters. But when they continually cried out to attack the enemy, and were impatient of delay, their inexperienced, disorderly rashness caused Sertorius much trouble, who at first strove to restrain them with reason and good counsel, but when he perceived them refractory and unseasonably violent, he gave way to their impetuous desires, and permitted them to engage with the enemy, in such sort that they might, being repulsed, yet not totally routed, become more obedient to his commands for the future. Which happening as he had anticipated, he soon rescued them, and brought them safe into his camp. And after a few days, being willing to encourage them again, when he had called all his army together, he caused two horses to be brought into the field, one an old, feeble, lean animal, the other a lusty, strong horse, with a remarkably thick and long tail. Near the lean one he placed a tall strong man, and near the strong young horse a weak despicable-looking fellow; and at a sign given, the strong man took hold of the weak horse's tail with both his hands, and drew it to him with his whole force, as if he would pull it off; the other, the weak man, in the mean time, set to work to pluck off hair by hair from the great horse's tail. And when the strong man had given trouble enough to himself in vain, and sufficient diversion to the company, and had abandoned his attempt, whilst the weak pitiful fellow in a short time and with little pains had left not a hair on the great horse's tail, Sertorius rose up and spoke to his army, "You see, fellow-soldiers, that perseverance is more prevailing than violence, and that many things which cannot be overcome when they are together, yield themselves up when taken little by little. Assiduity and persistence are irresistible, and in time overthrow and destroy the greatest powers whatever. Time being the favorable friend and assistant of those who use their judgment to await his occasions, and the destructive enemy of those who are unseasonably urging and pressing forward." With a frequent use of such words and such devices, he soothed the fierceness of the barbarous people, and taught them to attend and watch for their opportunities.
