in a second engagement they were put to flight; Cilicia and Tarsus were occupied by the enemy. Meanwhile in Armenia Philippicus had encamped at Valarsapat, but was compelled to beat a hurried retreat before the Persian forces. The Romans were repulsed on every side.
But the worst was not yet: with the year 614 came the overwhelming calamity of the fall of the Holy City. Advancing from Caesarea along the coast the Persians under Sahrbarâz arrived before Jerusalem in the month of April. Negotiations were put an end to by the violence of the circus factions, and the Roman relief force from Jericho, which was summoned by Modestus, was put to flight. The Persians pressed forward the siege, bringing up towers and rams, and finally breaching the walls on the twenty-first day from the investment of the city (? 3 or 5 May 614). For three days the massacre lasted, and the Jews joined the victors in venting their spite on their hated oppressors. We hear of 57,000 killed and 35,000 taken captive. Churches went up in flames, the patriarch Zacharias was carried into Persia and with him, to crown the disaster, went the Holy Cross. At the news Nicetas seems to have hastened to Palestine with all speed, but he could do no more than rescue the holy sponge and the holy lance, and these were despatched for safe custody to the capital. It was true that, when once Jerusalem was in his power, Chosroes was prepared to pursue a policy of conciliation: he deserted his former allies and the Jews were banished from the city, while leave was accorded to rebuild the ruined churches; but this did little to assuage the bitterness of the fact that a Christian empire had not been able to protect its most sacred sanctuary from the violence of the barbarian fire-worshipper.
In 615 the Persians began afresh that occupation of Asia Minor which had been interrupted by the evacuation of Caesarea in 611. When Sahîn marched towards Chalcedon, Philippicus invaded Persia, but the effort to draw off the enemy's forces proved unsuccessful. Asia Minor however was not Syria, and Sahîn realised that his position was insecure. He professed himself ready to consider terms of peace. Heraclius sailed over to the enemy's camp and from his ship carried on negotiations with the Persian general. Olympius, praetorian praefect, Leontius, praefect of the city, and Anastasius, the treasurer of St Sophia, were chosen as ambassadors, while the Senate wrote a letter to the Persian monarch in support of the Emperor's action. But as soon as Sahîn had crossed the frontier, the Roman envoys became prisoners and Chosroes would hear no word of peace.
Thus while Syria was lost to the Empire and while Slavs were ranging at will over the European provinces, Heraclius had to face the overwhelming problem of raising the necessary funds to carry on the war. Even from the scanty records which we possess of this period we can trace the Emperor's efforts towards economy: he reduced the number of the clergy who enjoyed office in the capital, and if any above
