4. For ten armed Persians stole out by a gate of the town of which he was not aware, and crawled on their hands and knees along the bottom of the hill, till they got within reach so as to fall silently upon our men, and two of them distinguishing the emperor by his superior appearance, made at him with drawn swords; but he encountered them with his shield raised, and protecting himself with that, and fighting with great and noble courage, he ran one of them through the body, while his guards killed the other with repeated blows. The rest, of whom some were wounded, were put to flight, and the two who were slain were stripped of their arms, and the emperor led back his comrades in safety, laden with their spoils, into the camp, where he was received with universal joy. 5. Torquatus took a golden necklace from one of the enemy whom he had slain. Valerius by the aid of a crow defeated a haughty Gaul and earned the surname of Corvinus, and by this glory these heroes were recommended to posterity. We do not envy them, but let this gallant exploit be added to those ancient memorials. 6. The next day a bridge was laid across the river, and the army passed over it, and pitched their camp in a fresh and more healthy place, fortifying it with a double rampart, since, as we have said, the open plains were regarded with apprehension. And then he undertook the siege of the town, thinking it too dangerous to march forward while leaving formidable enemies in his rear. 7. While he was making great exertions to complete his preparations, the Surena, the enemy's general, fell upon the cattle which were feeding in the palm groves, but was repulsed by those of our squadrons who were appointed to that service, and, having lost a few men, he retired. 8. And the inhabitants of two cities which are made islands by the rivers which surround them, fearing to trust in their means of defence, fled for refuge to Ctesiphon, some fleeing through the thick woods, others crossing the neighbouring marshes on canoes formed out of hollowed trees, and thus made a long journey to the principal or indeed the only shelter which existed for them, intending to proceed to still more distant regions. 9. Some of them were overtaken, and on their resistance were put to death by our soldiers, who, traversing various districts in barks and small boats, brought in from time to time many prisoners. For it had been cleverly arranged that, while the infantry was besieging the town, the squadrons of cavalry should scour the country in small bands in order to bring in booty. And by this system, without doing any injury to the inhabitants of the provinces, the soldiers fed on the bowels of the enemy.
