35. It happened that the same day on which these events [p. 1278]occurred, the ships which had carried the plunder to Sicily returned with provisions, as if divining that they came to take another cargo of booty. [2] All the writers do not vouch for the fact that two generals of the Carthaginians bearing the same name were slain in the battles of the cavalry; fearing, I believe, lest the same circumstance related twice should lead them into error. Caelius, indeed, and Valerius, make mention of a Hanno also who was made prisoner. [3] Scipio rewarded his officers and horsemen according to the service they had respectively rendered, but he presented Masinissa above all the rest with distinguished gifts. [4] Leaving a strong garrison at Saleca, he set out with the rest of his army; and having not only devastated the country wherever he marched, but taken some cities and towns, thus spreading the terrors of war far and wide, he returned to his camp on the seventh day after he set out, bringing with him an immense quantity of men and cattle, and booty of every description, and sent away his ships again loaded with the spoils of the enemy. [5] Then giving up all expeditions of a minor kind, and predatory excursions, he directed the [6??] whole force of the war to the siege of Utica, that he might make it for the time to come, if he took it, a position from which he might set out for the execution of the rest of his designs. [7] At one and the same time his marines attacked the city from the fleet in that part which is washed by the sea, and the land forces were brought up from a rising ground which almost immediately overhung the walls. [8] He had also brought with him engines and machines which had been conveyed from Sicily with the stores, and fresh ones were made in the armoury, in which he had for that purpose employed a number of artificers skilled in such works. The people of Utica, thus beset on all sides with so formidable a force, placed all their hopes in the Carthaginians, and the Carthaginians in the chance there was that Hasdrubal could induce Syphax to take arms. [9] But all their movements were made too slowly for the anxiety felt by those who were in want of assistance. [10] Hasdrubal, though he had by levies, conducted with the utmost diligence, made up as many as thirty thousand infantry and three thousand horse, yet dared not move nearer to the enemy before the arrival of Syphax. [11] Syphax came with fifty thousand foot and ten thousand horse, and, immediately [p. 1279]decamping from Carthage, took up a position not far from Utica and the Roman works. [12] Their arrival produced, however, this effect, that Scipio, who had been besieging Utica for forty days, during which he had tried every expedient without effect, left the place without accomplishing his object; [13] and as the winter was now fast approaching, fortified a camp for the winter upon a promontory, which being attached to the continent by a narrow isthmus, stretched out a considerable way into the sea. [14] He included his naval camp also within one and the same rampart. The camp for the legions being stationed on the middle of the isthmus, the ships, which were drawn on land, and the mariners occupied the northern shore, the cavalry a valley on the south inclining towards the other shore. [15] Such were the transactions in Africa up to the close of autumn.
