The consuls accordingly had by no means an easy task to perform, when they now found themselves compelled to commence a regular siege. Manius Manilius, who commanded the land army, pitched his camp opposite the wall of the citadel, while Lucius Censorinus stationed himself with the fleet on the lake and there began operations on the tongue of land. The Carthaginian army, under Hasdrubal, encamped on the other side of the lake near the fortress of Nepheris, whence it obstructed the labours of the Roman soldiers despatched to cut timber for constructing machines, and the able cavalry-leader in particular, Himilco Phameas, slew many of the Romans. Censorinus fitted up two large battering-rams on the tongue, and made a breach with them at this weakest place of the wall; but, as evening had set in, the assault had to be postponed. During the night the besieged succeeded in filling up a great part of the breach, and in so damaging the Roman machines by a sortie that they could not work next day. Nevertheless the Romans ventured on the assault; but they found the breach and the portions of the wall and houses in the neighbourhood so strongly occupied, and advanced with such imprudence, that they were repulsed with severe loss and would have suffered still greater damage, had not the military tribune Scipio Aemilianus, foreseeing the issue of the foolhardy attack, kept together his men in front of the walls and with them intercepted the fugitives. Manilius accomplished still less against the impregnable wall of the citadel. The siege thus lingered on. The diseases engendered in the camp by the heat of summer, the departure of Censorinus the abler general, the ill-humour and inaction of Massinissa who was naturally far from pleased to see the Romans taking for themselves the booty which he had long coveted, and the death of the king at the age of ninety which ensued soon after (end of 605), utterly arrested the offensive operations of the Romans. They had enough to do in protecting their ships against the Carthaginian incendiaries and their camp against nocturnal surprises, and in securing food for their men and horses by the construction of a harbour-fort and by forays in the neighbourhood. Two expeditions directed against Hasdrubal remained without success; and in fact the first, badly led over difficult ground, had almost terminated in a formal defeat. But, while the course of the war was inglorious for the general and the army, the military tribune Scipio achieved in it brilliant distinction. It was he who, on occasion of a nocturnal attack by the enemy on the Roman camp, starting with some squadrons of horse and taking the enemy in rear, compelled him to retreat. On the first expedition to Nepheris, when the passage of the river had taken place in opposition to his advice and had almost occasioned the destruction of the army, by a bold attack in flank he relieved the pressure on the retreating troops, and by his devoted and
