Heraclius returns to the West
[623-625

however, the Persian king fled before the invaders; the city fell, while the great temple which sheltered the fire of Usnasp was reduced to ruins. Heraclius followed after Chosroes, and sacked many cities on his march, but did not venture to press the pursuit: before him lay the enemy's country and the Persian army, while his rear might at any moment be threatened by the united advance of Sahrbarâz and Sahîn. Despite opposition, extreme cold, and scarcity of provisions he crossed the Araxes in safety, carrying some 50,000 prisoners in his train. It was shrewd policy which dictated their subsequent release; it created a good impression and, as a result, there were fewer mouths to feed.

It was doubtless primarily as a recruiting ground that Heraclius sought these Caucasian districts — the home of hardy and warlike mountaineers — for the sorely harried provinces of Asia Minor were probably in no condition to supply him with large contingents of troops. This is not however the place to recount in detail the complicated story of the operations of the winter of 623 and of the year 624. Sahîn was utterly discomfited at Tigranokert, but Heraclius was himself forced to retire into Armenia before the army of Sahrbarâz (winter, 623). With the spring of 624 we find Lazes, Abasges, and Iberians as Roman allies, though they subsequently deserted the Emperor when disappointed in their expectations of spoil and plunder. Heraclius was once more unable to penetrate into Persia, but was occupied in Armenia, marching and countermarching between forces commanded by Sarablangas, Sahrbarâz and Sahîn. Sarablangas was slain, and late in the year Van was captured, and Sarbar surprised in his winter quarters at Arces or Arsissa (at the N.E. end of Lake Van). The Persian general was all but taken prisoner, and very few of the garrison, 6000 strong, escaped destruction.

With the new year (625) Heraclius determined to return to the West, before he once more attempted a direct attack upon Persia. We can only conjecture the reasons which led him to take this step, but it would seem probable that the principal inducement was a desire to assert Roman influence in the south of Asia Minor and in the islands. The Persians had occupied Cilicia before the capture of Jerusalem; in 623 it would appear that they had made a raid upon Rhodes, had seized the Roman general and led off the inhabitants as prisoners, while in the same year we are told that the Slavs had entered Crete. There is some evidence which points to the conclusion that the Emperor was at this time very anxious to recover the ground thus lost. There was considerable doubt however as to which route should be pursued — that through Taranda or that by way of the Taurus chain. The latter was chosen despite its difficulty, as it was thought that provisions would be thus more plentiful. From Van the army advanced through Martyropolis and Amida, where the troops rested. But meanwhile Sahrbarâz, in hot pursuit, had arrived first at the Euphrates and removed the bridge of boats. The Emperor however crossed by a ford and reached Samosata
