Approximately 10,000 free persons of male sex were taken prisoner. Of these Scipio released those who were citizens of New Carthage, restoring to them their city and such property as the war had left them. There were also about 2,000 men who were skilled tradesmen. These, he declared, would be state property of the Roman people,* and added that they could hope for early emancipation if they were diligent in their work of providing war materials. All the others, large numbers of young resident aliens and able-bodied slaves, he put in the service of the fleet, to make up the numbers of his oarsmen (and he had also increased the size of the fleet with eighteen captured vessels*). In addition to this mass of people there were also the Spanish hostages, and these were treated with as much respect as if they were the children of allies.
The quantity of military equipment taken was enormous. There were 120 catapults of the largest dimensions, and 281 smaller ones; 23 large-scale and 52 smaller-scale ballistas; a huge number of the larger and smaller scorpions, and of weapons and projectiles; and 74 military standards. Large amounts of gold and silver were brought to the commander. There were 276 golden dishes, nearly all of them a pound in weight; there were 18,300 pounds of silver, in bullion and coin, and a large number of silver vessels. All this was weighed and counted, and then put in the charge of the quaestor, Gaius Flaminius. There were 400,000 measures of wheat and 270,000 of barley. Sixty-three transport vessels were overpowered and captured in the harbour, some with their cargoes of grain and weapons, as well as bronze and iron, sail-linen, rope, and other materials for equipping a fleet. The upshot was that amidst all these riches taken as the spoils of war New Carthage represented the least significant prize of all.
