16. By this time the mounds were raised to a considerable height, and the garrison, thinking that unless they used extraordinary vigilance their destruction must be at hand, resorted to extreme audacity; and making an unexpected sally from the gates, they attacked our front rank, and with all their might hurled firebrands and iron braziers loaded with fire against the rams.
17. But after a fierce but undecided conflict, the bulk of them were driven within the walls, without having succeeded in their attempt; and presently the battlements were attacked from the mounds which the Romans had raised, with arrows and slings and lighted javelins, which flew over the roofs of the towers, but did no harm, means having been prepared to extinguish any flames.
18. And as the ranks on both sides became thinner, and the Persians were now reduced to extremities unless some aid could be found, they prepared with redoubled energy a fresh sally from the camp: accordingly, they made a sudden sally, supported by increased numbers, and among the armed men were many bearing torches, and iron baskets full of fire, and faggots; and all kinds of things best adapted for setting fire to the works of the besiegers were hurled against them.
19. And because the dense clouds of smoke obscured the sight, when the trumpet gave the signal for battle, the legions came up with quick step; and as the eagerness of the conflict grew hotter, after they had engaged, suddenly all the engines, except the great ram, caught fire from the flames which were hurled at them; but the ropes which held the chief ram were broken asunder, and that the vigorous efforts of some gallant men saved, when it was half burnt.
20. When the darkness of night terminated the combat, only a short time was allowed to the soldiers for rest; but when they had been refreshed by a little food and sleep, they were awakened by their captains, and ordered to remove their works away from the walls of the town, and prepare to fight at closer quarters from the lofty mounds which were untouched by the flames, and now commanded the walls. And to drive the defenders from the walls, on the summit of the mounds they stationed two balistæ, in fear of which they thought that none of the enemy would venture even to look out.
21. After having taken these efficacious measures, a triple line of our men, having a more threatening aspect than usual from the nodding cones of their helmets (many of them also bearing ladders), attempted about twilight to scale the walls. Arms clashed and trumpets sounded, and both sides fought with equal boldness and ardour. The Romans, extending their lines more widely, when they saw the Persians hiding from fear of the engines which had been stationed on the mounds, battered the wall with their ram, and with spades, and axes, and levers, and ladders, pressed fiercely on, while missiles from each side flew without ceasing.
22. But the Persians were especially pressed by the various missiles shot from the balistæ, which, from the artificial mounds, came down upon them in torrents; and having become desperate, they rushed on, fearless of death, and distributing their force as if at the last extremity, they left some to guard the walls, while the rest, secretly opening a postern gate, rushed forth valiantly with drawn swords, followed by others who carried concealed fire.
23. And while the Romans at one moment were pressing on those who retreated, at another receiving the assault of those who attacked them, those who carried the fire crept round by a circuitous path, and pushed the burning coals in among the interstices of one of the mounds, which was made up of branches of trees, and rushes, and bundles of reeds. This soon caught fire and was utterly destroyed, the soldiers themselves having great difficulty in escaping and saving their engines.
24. But when the approach of evening broke off the conflict, and the two sides separated to snatch a brief repose, the emperor, after due reflection, resolved to change his plans. Although many reasons of great urgency pressed him to force on the destruction of Phœnice, as of a fortress which would prove an impregnable barrier to the inroads of the enemy, yet the lateness of the season was an objection to persevering any longer. He determined, therefore, while he preserved his position, to carry on the siege for the future by slight skirmishes, thinking that the Persians would be forced to surrender from want of provisions, which, however, turned out very different.
25. For while the conflict was proceeding sharply, the heavens became moist, and watery clouds appeared with threatening darkness; and presently the ground got so wet from continual rain, that the whole country was changed into an adhesive mud (for the soil is naturally rich), and every plan was thrown into confusion; meantime, thunder with incessant crashes and ceaseless lightning filled men's minds with fear.
