There are no military events which can be referred to the year A.D. 577. The Romans and Persians amused each other with alternate embassies during its course, and with negotiations that were not intended to have any result. The two monarchs made vast preparations; and with the spring of A.D. 578 hostilities recommenced. Chosroes is accused of having anticipated the expiration of the truce by a period of forty days; but it is more probable that he and the Romans estimated the date of its expiration differently. However this was, it is certain that his generals, Mebodes and Sapoes, took the field in early spring with 20,000 horse, and entering the Roman Armenia laid waste the country, at the same time threatening Constantina and Theodosiopolis. Simultaneously Tamchosro, quitting Persarmenia, marched westward and plundered the country about Amida (Diarbekr). The Roman commander Maurice, who had succeeded Justinian, possessed considerable military ability. On this occasion, instead of following the ordinary plan of simply standing on the defensive and endeavoring to repulse the invaders, he took the bolder course of making a counter movement. Entering Persarmenia, which he found denuded of troops, he carried all before him, destroying the forts, and plundering the country. Though the summer heats brought on him an attack of fever, he continued without pause his destructive march; invaded and occupied Arzanene, with its stronghold, Aphumon, carried off the population to the number of 10,090, and, pressing forwards from Arzanene into Eastern Mesopotamia, took Singara, and carried fire and sword over the entire region as far as the Tigris. He even ventured to throw a body of skirmishers across the river into Cordyene (Kurdistan); and these ravagers, who were commanded by Kurs, the Scythian, spread devastation over a district where no Roman soldier had set foot since its cession by Jovian. Agathias tells us that Chosroes was at the time enjoying his summer villeggiatura in the Kurdish hills, and saw from his residence the smoke of the hamlets which the Roman troops had fired. He hastily fled from the danger, and shut himself up within the walls of Ctesiphon, where he was soon afterwards seized with the illness which brought his life to a close.
