So long as he had to do with Metellus, he was thought to owe his successes to his opponent's age and slow temper, which were ill suited for coping with the daring and activity of one who commanded a light army more like a band of robbers than regular soldiers. But when Pompey also passed over the Pyrenees, and Sertorius pitched his camp near him, and offered and himself accepted every occasion by which military skill could be put to the proof, and in this contest of dexterity was found to have the better, both in baffling his enemy's designs and in counter-scheming himself, the fame of him now spread even to Rome itself, as the most expert commander of his time. For the renown of Pompey was not small, who had already won much honour by his achievements in the wars of Sylla, from whom he received the title of Magnus, and was called Pompey the Great; and who had risen to the honour of a triumph before the beard had grown on his face. And many cities which were under Sertorius were on the very eve of revolting and going over to Pompey, when they were deterred from it by that great action, amongst others, which he performed near the city of Lauron, contrary to the expectation of all.
For Sertorius had laid siege to Lauron, and Pompey came with his whole army to relieve it; and there being a hill near this city very advantageously situated, they both made haste to take it. Sertorius was beforehand, and took possession of it first, and Pompey, having drawn down his forces, was not sorry that it had thus happened, imagining that he had hereby enclosed his enemy between his own army and the city, and sent in a messenger to the citizens of Lauron, to bid them be of good courage, and to come upon their walls, where they might see their besieger besieged. Sertorius, perceiving their intentions, smiled, and said he would now teach Sylla's scholar, for so he called Pompey in derision, that it was the part of a general to look as well behind him as before him, and at the same time showed them six thousand soldiers, whom he had left in his former camp, from whence he marched out to take the hill, where, if Pompey should assault him, they might fall upon his rear. Pompey discovered this too late and not daring to give battle, for fear of being encompassed, and yet being ashamed to desert his friends and confederates in their extreme danger, was thus forced to sit still, and see them ruined before his face. For the besieged despaired of relief, and delivered up themselves to Sertorius, who spared their lives and granted them their liberty, but burnt their city, not out of anger or cruelty, for of all commanders that ever were Sertorius seemed least of all to have indulged these passions, but only for the greater shame and confusion of the admirers of Pompey, and that it might be reported amongst the Spaniards, that though he had been so close to the fire which burnt down the city of his confederates as actually to feel the heat of it, he still had not dared to make any opposition.
Sertorius, however, sustained many losses; but he always maintained himself and those immediately with him undefeated, and it was by other commanders under him that he suffered; and he was more admired for being able to repair his losses, and for recovering the victory, than the Roman generals against him for gaining these advantages; as at the battle of Sucro against Pompey, and at the battle near Tuttia, against him and Metellus together. The battle near the Sucro was fought, it is said, through the impatience of Pompey, lest Metellus should share with him in the victory, Sertorius being also willing to engage Pompey before the arrival of Metellus, Sertorius delayed the time till the evening, considering that the darkness of the night would be a disadvantage to his enemies, whether flying or pursuing, being strangers, and having no knowledge of the country.
