During the earlier portion of his reign Chosroes seems to have been engaged in but few wars, and those of no great importance. According to the Armenian writers, he formed a design of depopulating that part of Armenia which he had not ceded to the Romans, by making a general levy of all the males, and marching them off to the East, to fight against the Ephthalites; but the design did not prosper, since the Armenians carried all before them, and under their native leader, Smbat, the Bagratunian, conquered Hyrcania and Tabaristan, defeated repeatedly the Koushans and the Ephthalites, and even engaged with success the Great Khan of the Turks, who came to the support of his vassals at the head of an army consisting of 300.000 men. By the valor and conduct of Smbat, the Persian dominion was re-established in the north-eastern mountain region, from Mount Demavend to the Hindu Kush; the Koushans, Turks, and Ephthalitos were held in check; and the tide of barbarism, which had threatened to submerge the empire on this side, was effectually resisted and rolled back. With Rome Chosroes maintained for eleven years the most friendly and cordial relations. Whatever humiliation he may have felt when he accepted the terms on which alone Maurice was willing to render him aid, having once agreed to them, he stifled all regrets, made no attempt to evade his obligations, abstained from every endeavor to undo by intrigue what he had done, unwillingly indeed, but yet with his eyes open. Once only during the eleven years did a momentary cloud arise between him and his benefactor. In the year A.D. 600 some of the Saracenic tribes dependent on Rome made an incursion across the Euphrates into Persian territory, ravaged it far and wide, and returned with their booty into the desert. Chosroes was justly offended, and might fairly have considered that a _casus belli_ had arisen; but he allowed himself to be pacified by the representations of Maurice’s envoy, George, and consented not to break the peace on account of so small a matter. George claimed the concession as a tribute to his own amiable qualities; but it is probable that the Persian monarch acted rather on the grounds of general policy than from any personal predilection.
