is the name of Enannatum's father recorded, so that the suggestion has been made that they should be referred to Enannatum II., rather than to Enannatum I. But the adornment of the temple E-anna, recorded on the cones, is referred to in the clay-inscription of Enannatum I., which, like the cones, was found at El-Hibba.[9] It is reasonable therefore to assign the cone-inscription also to Enannatum I., and to conclude that Lummadur was his son, rather than the son and possible successor of Enannatum II. The cone-inscription records the installation of Lummadur by his father as priest in E-anna, when that temple had been adorned and embellished in honour of the goddess Ninni. Since Enannatum was succeeded upon the throne of Lagash by Entemena, we may assume that Lummadur was the latter's younger brother. One of the first duties Entemena was called upon to perform, after ascending the throne, was the defence of his territory against further encroachments by Urlumma. It is evident that this ruler closely watched the progress of events in Lagash, and such an occasion as the death of the reigning patesi in that city might well have appeared to him a suitable time for the renewal of hostilities. The death of the great conqueror Eannatum had already encouraged him to raid and occupy a portion of the territory held up to that time by Lagash, and, although Eannatum had succeeded in holding him to some extent in check, he only awaited a favourable opportunity to extend the area of territory under his control. Such an opportunity he would naturally see in the disappearance of his old rival, for there was always the chance that the new ruler would prove a still less successful leader than his father, or his accession might give rise to dissension among the members of the royal house, which would materially weaken the city's power of resistance. His attack appears to have been carefully organized, for there is evidence that he strengthened his own resources by seeking assistance from at least one other neighbouring state. His anticipation of securing a decided victory by this means was, however, far from being realized. Entemena lost no time in summoning his forces, and, having led them out into the plain of Lagash, he met the army of Urlumma at the frontier-ditch of Lummagirnunta, which his uncle Eannatum had constructed for the defence and irrigation of Gu-edin, the fertile territory of Ningirsu. Here he inflicted a signal defeat upon the men of Umma, who, when routed and put to flight, left sixty of their fellows lying dead upon the banks of the canal.[10] Urlumma himself fled from the battle, and sought safety in his own city. But Entemena did not rest content with the defeat he had inflicted upon the enemy in the field. He pursued the men of Umma into their own territory, and succeeded in capturing the city itself before its demoralized inhabitants had had time to organize or strengthen its defence.
