[-48-] When Pompey went on procuring these in safety and through certain men's help had become master of the land of Anaitis, which belongs to Armenia and is dedicated to some god after whom it is named, and many others kept seceding to him, while the soldiers of Marcius were added to his force, Mithridates becoming frightened no longer kept his position, but immediately started unobserved in the night, and thereafter by night marches advanced into the Armenia of Tigranes. Pompey followed on, eager to secure a battle. This, however, he could not do by day, for they would not come out of their camp, and he did not venture the attempt by night, fearing his ignorance of the country, until they got near the frontier. Then, knowing that they would escape, he was compelled to have a night battle. Having decided on this course he started off before them at noontime, unobserved of the barbarians, by the road along which they were to march. Finding a sunken part of the road, between some low hills, he there stationed his army on the higher ground and awaited the enemy. When the enemy entered the sunken way, with confidence and without an advance guard (since they had suffered no injury previously and now at last were gaining safety, so that they expected that the Romans would no longer follow them), he fell upon them in the darkness. There was no illumination from heaven and they had no kind of light. [-49-] The nature of the ensuing battle I will now describe. First, all the trumpeters together at a signal sounded the attack, next the soldiers and all the multitude raised a shout, some rattling their spears against their shields, and others stones against the bronze implements. The hollowed mountains took up and gave back their din with most frightful effect, so that the barbarians, hearing them suddenly in the night and the wilderness, were terribly alarmed, thinking they had encountered some supernatural phenomenon. Directly the Romans from the heights smote them at all points with stones, arrows, and javelins, inevitably wounding some by reason of their numbers, and reduced them to every extremity of evil. They were not drawn up in line of battle, but for marching, and both men and women were moving about in the same place with horses and camels and all sorts of implements; some were borne on coursers, others on chariots, covered wagons, and carts indiscriminately; and some getting wounded already and others expecting to be wounded caused confusion, in consequence of which they were more easily slain, since they kept becoming entangled one with another. This was what they endured while they were still being struck from afar off. But when the Romans after exhausting their long-distance ammunition charged down upon them, the edges of the force were slaughtered, one blow sufficing for their death, since the majority were unarmed, and the center was crushed together, as all by reason of the encompassing fear fell toward it.
