The battle was long and bloody, and the issue uncertain; Shalmaneser drove back one wing of the confederate army to the Orontes, and forcing the other wing and the centre to retire from Qarqar to Kirzau, claimed the victory, though the losses on both sides were equally great. It would seem as if the battle were indecisive--the Assyrians, at any rate, gained nothing by it; they beat a retreat immediately after their pretended victory, and returned to their own land without prisoners and almost without booty. On the whole, this first conflict had not been unfavourable to Damascus: it had demonstrated the power of that state in the eyes of the most incredulous, and proved how easy resistance would be, if only the various princes of Syria would lay aside their differences and all unite under the command of a single chief. The effect of the battle in Northern Syria and among the recently annexed Aiamoan tribes was very great; they began to doubt the omnipotence of Assyria, and their loyalty was shaken. Sangar of Carchemish and the Khati refused to pay their tribute, and the Emirs of Tul-Abni and Mount Kashiari broke out into open revolt. Shalmaneser spent a whole year in suppressing the insurrection; complications, moreover, arose at Babylon which obliged him to concentrate his attention and energy on Chaldaean affairs. Nabu-baliddin had always maintained peaceful and friendly relations with Assyria, but he had been overthrown, or perhaps assassinated, and his son Marduk-nadin-shumu had succeeded him on the throne, to the dissatisfaction of a section of his subjects. Another son of Nabu-baliddin, Marduk-belusate, claimed the sovereign power, and soon won over so much of the country that Marduk-nadin-shumu had fears for the safety of Babylon itself. He then probably remembered the pretensions to Kharduniash, which his Assyrian neighbours had for a long time maintained, and applied to Shalmaneser to support his tottering fortunes. The Assyrian monarch must have been disposed to lend a favourable ear to a request which allowed him to intervene as suzerain in the quarrels of the rival kingdom: he mobilised his forces, offered sacrifices in honour of Bamman at Zaban, and crossed the frontier in 853 B.C.* The war dragged on during the next two years. The scene of hostilities was at the outset on the left bank of the Tigris, which for ten centuries had served as the battle-field for the warriors of both countries. Shalmaneser, who had invested Me-Turnat at the fords of the Lower Diyalah, at length captured that fortress, and after having thus isolated the rebels of Babylonia proper, turned his steps towards G-ananate.** * The town of Zaban is situated on the Lesser Zab, but it is impossible to fix the exact site.
