Having thus secured his rear from attack for some years at any rate, Tiglath-pileser no longer hesitated to try conclusions with Urartu. The struggle in which he now deliberately engaged could not fail to be a decisive one; for Urartu, buoyed up and borne on the wave of some fifty years of prosperity, had almost succeeded in reaching first rank among the Asiatic powers: one more victory over Nineveh, and it would become--for how long none might say--undisputed mistress of the whole of Asia. Assyria, on the other hand, had reached a. point where its whole future hung upon a single issue of defeat or victory. The prestige with which the brilliant campaigns of Assur-nazir-pal and Shalmaneser III. had invested its name, if somewhat diminished, had still survived its recent reverses, and the terror inspired by its arms was so great even among races who had witnessed them from a distance, that the image of Assyria rose involuntarily before the eyes of the Hebrew prophets as that of the avenger destined to punish Israel for its excesses.* * Cf. Amos vi. 4. No doubt, during the last few reigns its prosperity had waned and its authority over distant provinces had gradually become relaxed; but now the old dynasty, worn out by its own activity, had given place to a new one, and with this change of rulers the tide of ill-fortune was, perhaps, at last about to turn. At such a juncture, a successful campaign meant full compensation for all past disasters and the attainment of a firmer position than had ever yet been held; whereas another reverse, following on those from which the empire had already suffered, would render their effect tenfold more deadly, and, by letting loose the hatred of those whom fear alone still held in check, complete its overthrow. It was essential, therefore, before entering on the struggle, to weigh well every chance of victory, and to take every precaution by which adverse contingencies might be, as far as possible, eliminated. The army, encouraged by its success in the two preceding campaigns, was in excellent fighting order, and ready to march in any direction without a moment's hesitation, confident in its ability to defeat the forces of Urartu as it had defeated those of the Medes and Aramaeans; but the precise point of attack needed careful consideration. Tiglath-pileser must have been sorely tempted to take the shortest route, challenge the enemy at his most vulnerable point on the shores of Lake Van, and by a well-aimed thrust deal him a blow from which he would never, or only by slow degrees, recover. But this vital region of Urartu, as we have already pointed out, presented the greatest difficulties of access. The rampart of mountain and forest by which it was protected on the Assyrian side could only be traversed by means of a few byways, along which bands of guerrillas could slip down easily enough to the banks of the Tigris, but which were quite impassable to
