With the whole south of the country in arms against him, we may conjecture that Samsu-iluna detailed sufficient forces to contain Rîm-Sin, while he dealt with the invasion of Babylon's home-territory. He had little difficulty in disposing of the Elamites, and, marching southwards, he defeated Rîm-Sin's forces and reoccupied Larsa.[2] It may be that it was at this time he captured, or burnt, Rîm-Sin alive,[3] and that the palace where this took place was the rebel leader's old palace at Larsa, which he had been making his headquarters. But the revolt was not completely subdued. Ur and Erech still held out, and it was only after a further campaign that Samsu-iluna recaptured them and razed their walls. He had thus succeeded in crushing the first series of organized attacks upon the empire, but the effort of dealing simultaneously with invasion and internal revolt had evidently strained the national resources. Garrisons had probably been reduced in distant provinces, others had been cut down in order to reinforce his armies in the field, and it is not surprising that in his twelfth year these outlying districts should have followed the prevailing lead. In that year it is recorded that all the lands revolted against him.[4] [Illustration: IMPRESSIONS OF KASSITE CILINDER SEALS. _Brit. Mus., Nos._ 89128, 89001, 28799, 89240, 89258.] We may with some confidence trace the main source of Samsu-iluna's fresh troubles to the action of Iluma-ilum, who, probably at this time, headed a revolt in the Sea-Country on the shore of the Persian Gulf, and declared his independence of Babylon. Samsu-iluna's answer was to raise further levies and lead them against his new foe. The subsequent battle was fiercely contested on the very shore of the Gulf, for a later chronicler records that the bodies of the slain were carried off by the sea; yet it was either indecisive, or resulted in the discomfiture of the Babylonians. We may conjecture that the king was prevented from employing his full forces to stamp out the rebellion, in consequence of trouble in other quarters. For in the following two years we find him destroying the cities Kisurra and Sabum, and defeating the leader of a rebellion in the home-territory of Babylon itself.[5]
