2. Therefore he ordered Jovinus, the captain of his cavalry, who was marching over the Alps, and had entered Noricum, to return with all speed, to remedy by some means or other, the evil which had burst out. And, that nothing might be wanting, he bade him retain all the soldiers who were marching after his court or his standards and passing through that town, and to avail himself of their help to the utmost. 3. When he had made these arrangements, having soon afterwards heard of the death of Constantius, he crossed through Thrace, and entered Constantinople: and having been often assured that the siege would be protracted rather than formidable, he sent Immo with some other counts to conduct it; and removed Jovinus to employ him in other matters of greater importance. 4. Therefore, having surrounded Aquileia with a double line of heavy infantry, the generals all agreed upon trying to induce the garrison to surrender, using alternately threats and caresses; but after many proposals and replies had been interchanged, their obstinacy only increased, and the conferences were abandoned, having proved wholly ineffectual. 5. And because there was now no prospect but that of a battle, both sides refreshed themselves with sleep and food; and at daybreak the trumpets sounded, and the two armies, arrayed for reciprocal slaughter, attacked one another with loud shouts, but with more ferocity than skill. 6. Therefore the besiegers, bearing wooden penthouses over them, and closely woven wicker defences, marched on slowly and cautiously, and attempted to undermine the walls with iron tools: many also bore ladders which had been made of the height of the walls, and came up close to them: when some were dashed down by stones hurled on their heads, others were transfixed by whizzing javelins, and falling back, dragged with them those who were in their rear; and others, from fear of similar mischances, shrank from the attack. 7. The besieged being encouraged by the issue of this first conflict, and hoping for still better success, disregarded the rest of the attacks made on them; and with resolute minds they stationed engines in suitable positions, and with unwearied toil discharged the duties of watching and of whatever else could tend to their safety. 8. On the other hand, the besiegers, though fearing another combat, and full of anxiety, still out of shame would not appear lazy or cowardly, and as they could make no way by open attacks, they also applied themselves to the various manoeuvres employed in sieges. And because there was no ground favourable for working battering-rams or other engines, nor for making mines, since the river Natiso passed under the walls of the city, they contrived a plan worthy to be compared with any effort of ancient skill.
