13. When the next day showed the slaughter which had been made, nobles and satraps were found lying amongst the corpses, and all kinds of dissonant cries and tears indicated the changed posture of the Persian host: everywhere was heard wailing; and great indignation was expressed by the princes, who thought that the Romans had forced their way through the sentries in front of the walls. A truce was made for three days by the common consent of both armies, and we gladly accepted a little respite in which to take breath.[105] VII. § 1. Now the nations of the barbarians, being amazed at the novelty of this attempt, and rendered by it more savage than ever, discarding all delay, determined to proceed with their works, since open assaults availed them but little. And with extreme warlike eagerness they all now hastened to die gloriously, or else to propitiate the souls of the dead by the ruin of the city. 2. And now, the necessary preparations having been completed by the universal alacrity, at the rising of the day-star all kinds of structures and iron towers were brought up to the walls; on the lofty summits of which balistæ were fitted, which beat down the garrison who were placed on lower ground. 3. And when day broke the iron coverings of the bodies of the foe darkened the whole heaven, and the dense lines advanced without any skirmishers in front, and not in an irregular manner as before, but to the regular and soft music of trumpets; protected by the roofs of the engines, and holding before them wicker shields. 4. And when they came within reach of our missiles, the Persian infantry, holding their shields in front of them, and even then having difficulty in avoiding the arrows which were shot from the engines on the walls, for scarcely any kind of weapon found an empty space, they broke their line a little; and even the cuirassiers were checked and began to retreat, which raised the spirits of our men. 5. Still the balistæ of the enemy, placed on their iron towers, and pouring down missiles with great power from their high ground on those in a lower position, spread a great deal of slaughter in our ranks. At last, when evening came on, both sides retired to rest, and the greater part of the night was spent by us in considering what device could be adopted to resist the formidable engines of the enemy. 6. At length, after we had considered many plans, we determined on one which the rapidity with which it could be executed made the safest--to oppose four scorpions to the four balistæ; which were carefully moved (a very difficult operation) from the place in which they were; but before this work was finished, day arrived, bringing us a mournful sight, inasmuch as it showed us the formidable battalions of the Persians, with their trains of elephants, the noise and size of which animals are such that nothing more terrible can be presented to the mind of man.
