51. Scipio kept Laelius by him until with his advice he should dispose of captives and hostages and the booty. [2] then when everything had been properly arranged, he furnished him with a quinquereme,¹ put on shipboard the captives with Mago and about fifteen senators who had been captured with him, and sent Laelius to Rome to report the victory. [3] he himself spent the few days during which he had decided to remain at (New) Carthage in drilling his naval and land forces. [4] on the first day the legions would run under arms for four miles; on the second they were ordered to take care of their arms and clean them in front of their tents; on the third day with wooden foils they encountered each other after the manner of a regular battle and hurled missile weapons provided with a button at the end; on the fourth day they were given a rest; on the fifth they again ran quickly under arms. [5] this disposition of work and rest they maintained so long as they remained at (New) Carthage. [6] the oarsmen and marines, when the sea was calm, would sail out into open water and test the mobility of their ships in sham naval battles. [7] such training outside the city by land and sea steeled both bodies and minds for war. the city itself rang with preparations for war, since artisans [p. 197]of all kinds were shut up in public workshops. [8] the² general inspected everything with the same care; now he was on the fleet and the docks, now he was with the legions as they ran; now he was giving his time to viewing the work that was done from day to day in shops and arsenal and on the docks, with the utmost rivalry, by the great multitude of artisans. [9] having made such a beginning, and having repaired battered parts of the wall, and leaving forces posted to defend the city, he set out for Tarraco, being approached by many embassies in the course of his march. [10] some of these he answered and dismissed without stopping, some he postponed till he reached Tarraco, at which he had announced an assembly for all the allies new and old. [11] and nearly all the peoples dwelling on this side of the Ebro came together, and many also from the farther province.

the Carthaginian commanders at first purposely suppressed the news of the capture of (New) Carthage. [12] then, when the matter was too well known to be concealed or masked, their language would minimize it, saying that by a sudden arrival and almost by stealth on a single day a single city of Spain had been seized; and carried away by success on so small a scale, an arrogant youth in an excess of joy had given it the appearance of a great victory; [13] but when he heard that three generals, three victorious armies of the enemy were approaching, there would at once come to him the memory of the losses in his family. [14] such were their remarks in public, but in themselves they were by no means unaware what a mass of resources for every purpose had gone with the loss of (New) Carthage.
