4. Thereupon he directed his guidon-bearer,¹ Aulus Baeculonius, a man of tried courage, to carry forward the standard. He replied that if they would follow him he would cause it to happen the more quickly; [2] and when with a great effort he had hurled the standard over the rampart, he was the first of all to enter the gate.² [3] And on another side Titus and Gaius Aelius, military tribunes of the third legion, were coming up with the cavalry. Straightway also came the soldiers whom they had mounted in pairs on the pack-animals, and the consul with the main body. [4] But a few of the Histrians, who had indulged only moderately in the wine, bethought them of flight, for the rest, death was a prolongation of sleep; and the Romans recovered their possessions in their entirety, except for the wine and food that had been consumed. [5] Even the sick troops, who had been left inside the camp, when they learned that their comrades were within the rampart, seized their arms and wrought great slaughter. [6] Conspicuous beyond the rest was the performance of a trooper, Gaius Popilius; his cognomen was Sabellus. He, though wounded in the foot and left behind, killed by far the largest number of the enemy. [7] About eight thousand of the Histrians were slain, none [p. 197]captured, for rage and passion made the Romans³ heedless of booty. Nevertheless the chieftain of the Histrians, drunk as he was from the banquet, was hastily placed on a horse by his companions and escaped. [8] Of the victors two hundred and thirty-seven fell, more in the flight in the morning than in the retaking of the camp.
