The natural result followed. Kobad at once declared war. The two empires had now been uninterruptedly at peace for sixty, and, with the exception of a single campaign (that of A.D. 441), for eighty years. They had ceased to feel that respect for each other’s arms and valor which experience gives, and which is the best preservative against wanton hostilities. Kobad was confident in his strength, since he was able to bring into the field, besides the entire force of Persia, a largo Ephthalite contingent, and also a number of Arabs. Anastasius, perhaps, scarcely thought that Persia would go to war on account of a pecuniary claim which she had allowed to be disregarded for above half a century. The resolve of Kobad evidently took him by surprise; but he had gone too far to recede. The Roman pride would not allow him to yield to a display of force what he had refused when demanded peacefully; and he was thus compelled to maintain by arms the position which he had assumed without anticipating its consequences.
The war began by a sudden inroad of the host of Persia into Roman Armenia, where Theodosiopolis was still the chief stronghold and the main support of the Roman power. Unprepared for resistance, this city was surrendered after a short siege by its commandant, Constantine, after which the greater part of Armenia was overrun and ravaged. From Armenia Kobad conducted his army into Northern Mesopotamia, and formed the siege of Amida about the commencement of the winter. The great strength of Amida has been already noticed in this volume. Kobad found it ungarrisoned, and only protected by a small force, cantoned in its neighborhood, under the philosopher, Alypius. But the resolution of the townsmen, and particularly of the monks, was great; and a most strenuous resistance met all his efforts to take the place. At first his hope was to effect a breach in the defences by means of the ram; but the besieged employed the customary means of destroying his engines, and, where these failed, the strength and thickness of the walls was
