The Roman History · Amm. 24.4.4

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.
