XXXIX. This misfortune greatly annoyed, as we may suppose, all the soldiers of Antonius, who at the commencement of the war had received this unexpected blow; and the Armenian Artavasdes despairing of the success of the Romans went off with his troops, though he had been the chief cause of the war. The Parthians now showed themselves to the besiegers in gallant array and insultingly threatened them, on which Antonius, not wishing to let despondency and dejection abide in his army by their being quiet and to increase, took ten legions and three prætorian cohorts of heavy-armed men and all the cavalry, and led them out to forage in the hope that the enemy would thus be drawn on, and that a regular battle would ensue. After advancing one day's march, he saw that the Parthians were spreading themselves around him and seeking to attack him on the march, on which he hung out in the camp the sign of battle, but at the same time he ordered the tents to be taken down, as if his intention were not to fight but to lead off his troops; and he passed along the line of the barbarians, which was in the form of a crescent, having given orders, as soon as the first ranks of the enemy should be within reach of the heavy-armed soldiers, for the cavalry to ride at them. To the Parthians who stood opposed to the Romans, their discipline appeared to be something indescribable; and they observed the Romans as they marched past at equal intervals without disorder and in silence, brandishing their spears. But when the standard was raised and the cavalry facing about rushed upon the enemy, the Parthians received their onset and repelled it, though the Romans were all at once too close to allow them to use their arrows; but when the heavy-armed soldiers joined in the conflict at the same time with shouts and the clatter of arms, the Parthian horses were frightened and gave way and the Parthians fled before they came to close quarters. Antonius pressed on the pursuit, and had great hopes that he had finished the whole war or the chief part in that battle. But when the infantry had followed up the pursuit for fifty stadia and the cavalry for three times that distance, looking at those of the enemy who had fallen and were captured, they found only thirty captives and eighty corpses, which caused dismay and despondency in all the army, when they reflected that though victorious they had killed so few, and that when defeated they must sustain such a loss as they had near the waggons. On the following day they broke up their encampment and took the road towards Phraata and the camp. On their march they fell in at first with a few of the enemy, and then a greater number, and finally with all, who, as if they were unvanquished and fresh, challenged them and fell upon them from all sides, so that with difficulty and much labour they got safe to their camp. As the Medes made a sally against the mound and terrified those
