But it was not long before fresh changes occurred.  Tammarit, finding himself little more than puppet-king in the hands of the Assyrians, formed a plot to massacre all the foreign troops left to garrison this country, and so to make himself an independent monarch.  His intentions, however, were discovered, and the plot failed.  The Assyrians seized him, put him in bonds, and sent him to Nineveh.  Western Elam passed under purely military rule, and suffered, it is probable, extreme severities.  Under these circumstances, Umman-aldas took heart, and made ready, in the fastnesses to which he had fled, for another and a final effort.  Having levied a vast army, he, in the spring of the next year, made himself once more master of Bit-Imbi, and, establishing himself there, prepared to resist the Assyrians.  Their forces shortly appeared; and, unable to hold the place against their assaults, Umman-aldas evacuated it with his troops, and fought a retreating fight all the way back to Susa, holding the various strong towns and rivers in succession.  Gallant, however, as was his resistance it proved ineffectual.  The lines of defence which he chose were forced, one after another; and finally both Susa and Badaca were taken, and the country once more lay at Asshur-bani-pal’s mercy.  All the towns made their submission.  Asshur-bani-pal, burning with anger at their revolt, plundered the capital of its treasures, and gave the other cities up to be spoiled by his soldiers for the space of a month and twenty-three days.  He then formally abolished Susianian independence, and attached the country as a province to the Assyrian empire.  Thus ended the Susianian war, after it had lasted, with brief interruptions, for the space of (probably) twelve years.

The full occupation given to the Assyrian arms by this long struggle encouraged revolt in other quarters.  It was probably about the time when Asshur-bani-pal was engaged in the thick of the contest with Umman-ibi and Saul-Mugina that Psammetichus declared himself independent in Egypt, and commenced a war against the princes who remained faithful to their Assyrian suzerain.  Gyges, too, in the far north-west, took the opportunity to break with the formidable power with which he had recently thought it prudent to curry favor, and sent aid to the Egyptian rebel, which rendered him effective service.  Egypt freed herself from the Assyrian yoke, and entered on the prosperous period which is known as that of the twenty-sixth (Saite) dynasty.  Gyges was less fortunate.  Assailed shortly by a terrible enemy, which swept with resistless force over his whole land, he lost his life in the struggle.  Assyria was well and quickly avenged; and Ardys, the new monarch, hastened to resume the deferential attitude toward Asshur-bani-pal which his father had unwisely relinquished.
