At daybreak, Asdrubal, perceiving the ignominious defeat of his troops, in order to be revenged upon the Romans and to deprive the inhabitants of all hopes of accommodation and pardon, brought all the Roman prisoners he had taken, upon the walls, in sight of both armies. There he put them to the most exquisite tortures, plucking out their eyes, cutting off their noses, ears, and fingers; tearing their skin from their bodies with iron rakes or harrows, and then threw them from the top of the battlements. Such inhumanity filled the Carthaginians even with horror; he, however, did not spare them, but murdered many senators who had ventured to oppose his cruelty and tyranny. This was a worthy descendant of the Carthaginians who in the first Punic war tortured Regulus. Scipio, finding himself master of the isthmus, burnt the camp the enemy had deserted, and built a new one for his troops. It was of a square form, surrounded with strong and deep intrenchments, and fenced with large palisades; on the side which faced the Carthaginians, he built a wall twelve feet high, flanked at proper distances with towers and redoubts; and on the middle tower he erected a very high wooden fort, whence everything could be seen that was going on in the city. This wall was equal to the whole breadth of the isthmus,--that is, twenty-five stadia. The enemy, who were within bow-shot of it, employed their utmost efforts to put a stop to this work; but as the whole army were engaged in it night and day without intermission, it was finished in twenty-four days. Scipio reaped a double advantage from this work: first, his forces were lodged more safely and commodiously; secondly, he cut off all supplies of provisions from the besieged, to whom none could now be brought but by sea, which was attended with many difficulties, arising from the frequency of tempests and the good guard kept by the Roman fleet. This proved one of the chief causes of the famine which raged soon after in the city. Besides, Asdrubal distributed the corn that was brought only among the thirty thousand men who served under him, caring little what became of the rest of the inhabitants.
