Mabog or Hierapolis, Kenneserin, and Berhoea (now Aleppo), were invested and taken in the course of one or at most two campaigns; while at the same time (A.D. 609) a second Persian army, under a general whose name is unknown, after operating in Armenia, and taking Satala and Theodosiopolis, invaded Cappadocia and threatened the great city of Caesarea Mazaca, which was the chief Roman stronghold in these parts. Bands of marauders wasted the open country, carrying terror through the fertile districts of Phyrgia and Galatia, which had known nothing of the horrors of war for centuries, and were rich with the accumulated products of industry. According to Theophanes, some of the ravages even penetrated as far as Chalcedon, on the opposite side of the straits from Constantinople; but this is probably the anticipation of an event belonging to a later time. No movements of importance are assigned to A.D. 610; but in the May of the next year the Persians once more crossed the Euphrates, completely defeated and destroyed the Roman army which protected Syria, and sacked the two great cities of Apameia and Antioch. Meantime a change had occurred at Constantinople. The double revolt of Heraclius, prefect of Egypt, and Gregory, his lieutenant, had brought the reign of the brutal and incapable Phocas to an end, and placed upon the imperial throne a youth of promise, innocent of the blood of Maurice, and well inclined to avenge it. Chosroes had to consider whether he should adhere to his original statement, that he took up arms to punish the murderer of his friend, and benefactor, and consequently desist from further hostilities now that Phocas was dead, or whether, throwing consistency to the winds, he should continue to prosecute the war, notwithstanding the change of rulers, and endeavor to push to the utmost the advantage which he had already obtained. He resolved on this latter alternative. It was while the young Heraclius was still insecure in his seat that he sent his armies into Syria, defeated the Roman troops, and took Antioch and Apameia. Following up blow with blow, he the next year (A.D. 612) invaded Cappadocia a second time and captured Csesarea Mazaca. Two years later (A.D. 614) he sent his general Shahr-Barz, into the region east of the Antilibanus, and took the ancient and famous city of Damascus. From Damascus, in the ensuing year, Shahr-Barz advanced against Palestine, and, summoning the Jews to his aid, proclaimed a Holy War against the Christian misbelievers, whom he threatened to enslave or exterminate. Twenty-six thousand of these fanatics flocked to his standard; and having occupied the Jordan region and Galileee, Shahr-Barz in A.D. 615 invested Jerusalem, and after a siege of eighteen days forced his way into the town, and gave it over to plunder and rapine. The cruel hostility of the Jews had free vent. The churches of Helena, of Constantine, of the Holy Sepulchre, of the
