exceedingly great quantity; and thus he departed from the land of the Romans. For this reason it was that Chosroes claimed that the city belonged to him from his fathers.
And when he reached Daras, he began a siege; but within the city the Romans and Martinus, their general (for it happened that he was there), made their preparations for resistance. Now the city is surrounded by two walls, the inner one of which is of great size and a truly wonderful thing to look upon (for each tower reaches to a height of a hundred feet, and the rest of the wall to sixty), while the outer wall is much smaller, but in other respects strong and one to be reckoned with seriously. And the space between has a breadth of not less than fifty feet; in that place the citizens of Daras are accustomed to put their cattle and other animals when an enemy assails them. At first then Chosroes made an assault on the fortifications toward the west, and forcing back his opponents by overwhelming numbers of missiles, he set fire to the gates of the small wall. However no one of the barbarians dared to get inside. Next he decided to make a tunnel secretly at the eastern side of the city. For at this point alone can the earth be dug, since the other parts of the fortifications were set upon rock by the builders. So the Persians began to dig, beginning from their trench. And since this was very deep, they were neither observed by the enemy nor did they afford them any means of discovering what was being done. So they had already gone under the foundations of the outer wall, and were about to reach the space between the two walls and soon after to pass also the great wall and take the city by force; but since it was not fated to be captured by the Persians, someone from the camp of Chosroes came alone about midday close to the fortifications, whether a man or something else greater than man, and he made it appear to those who saw him that he was collecting the weapons which the Romans had a little before discharged from the wall against the barbarians who were assailing them. And while doing this and holding his shield before him, he seemed to be bantering those who were on the parapet and taunting them with laughter. Then he told them of everything and commanded them all to be on the watch and to take all possible care for their safety. After revealing these things he was off, while the Romans with much shouting and confusion were ordering men to dig the ground between the two walls. The Persians, on the other hand, not knowing what was being done, were pushing on the work no less than before. So while the Persians were making a straight way underground to the wall of the city, the Romans by the advice of Theodoras, a man learned in the science called mechanics, were constructing their trench in a cross-wise direction and making it of sufficient depth, so that when the Persians had reached the middle point between the two circuit-walls they suddenly broke into the trench of the Romans. And the first of them the Romans killed, while those in the rear by fleeing at top speed into the camp saved themselves. For the Romans decided by no means to pursue them in the dark. So Chosroes, failing in this attempt and having no hope that he would take the city by any device thereafter, opened negotiations with the besieged, and carrying away a thousand pounds of silver he retired into the land of Persia. When this came to the knowledge of the Emperor Justinian, he was no longer willing to carry the agreement into effect, charging Chosroes with having attempted to capture the city of Daras during a truce. Such were the fortunes of the Romans during the first invasion of Chosroes; and the summer drew to its close.
