Out of the war against the Lusitanians, in which Galba by his faithlessness had branded the Roman name with dishonour, that of Viriathus sprang. This man, who was a Lusitanian, had been a common shepherd and also a robber, as is very often the case with herdsmen in southern Europe, even as it is to this very day in Italy; and having been among those Lusitanians towards whom Galba had behaved with such infamous treachery, he had vowed implacable revenge against the Romans. He placed himself at the head of a small band; for in Spain it is characteristic of the nation to have a continual guerilla warfare, for which the Spaniards have a turn, owing to the nature of their country, and also from their disposition, law and order not having the least power over them, while personal qualities are everything. Viriathus enjoyed unbounded confidence as the hero of the nation. He seldom engaged with the Romans in a pitched battle; but to lie in ambush, to cut off supplies, to go round the enemy, to scatter quickly after a defeat, were the ways in which he would wage war. By his great skill he wore out the Roman generals, more than one of whom lost his life against him. The history of his achievements, imperfectly as we know it, is exceedingly interesting. For eight years[61] (605-612), he maintained himself against the Romans; they would march against him with a superior force, and yet he always got out of their reach, and then would suddenly show himself in their rear, or hem them in on impassable roads, and rob them of their baggage, and cut them to pieces in detail. By these means, he gained the whole of the country for himself; only the inhabitants of the coast of Andalusia, who had ever been the least warlike, remained subject to the Romans, being quickly latinized. Among these, therefore, Viriathus made his appearance as a foe; but the ground which was particularly friendly to him, lay from Portugal, all through Estremadura, as far as Aragon: here he moved remarkably quickly with his light horse and foot. Seldom did he meet with loss against the Romans. The Celtiberians also he managed to win over to his side: they did not indeed carry on their warfare according to his plan, but still, as is always the case with Spaniards, they sought the same end in a way of their own. The Romans saw themselves reduced to the necessity of concluding with him a formal peace, in which they acknowledge him as _socius_ and _amicus populi Romani æquissimo jure_, and by which he and his people became completely sovereign,--a peace the like of which the Romans had hardly ever made before. On his side it was honestly meant; whereas the Romans, on the contrary, did not deem themselves bound to keep a treaty which was so utterly at variance with their maxims. The Roman proconsul Cæpio wished for a triumph and booty, like all the Roman generals of that time; and so he rekindled the war, having with an utter want of faith
