The other conquests recorded in the inscriptions of Eannatum fall into two groups. In all the lists of his victories that have come down to us--on the Stele of the Vultures, the foundation-stones, and the brick-inscriptions--the defeat of Elam is given the first place. This is probably not to be taken as implying that it was the first in order of time. It is true that the order in which the conquered districts and cities are arranged is generally the same in the different lists, but this is not invariably the case. Apart from differences caused by the omission or insertion of names, the order is sometimes altered; thus the conquest of Arua is recorded before that of Ur on the Stele of the Vultures, whereas on the foundation-stones this arrangement is reversed. It would, therefore, be rash to assume that they were enumerated in the order of their occurrence; it is more probable that the conquered states and districts are grouped on a rough geographical basis, and that these groups are arranged according to the importance attaching to them. That Elam should always be mentioned first in the lists is probably due to the fact that she was the hereditary enemy of the cities of Sumer and Akkad, whose rulers could never be sure of immunity from her attacks. The agricultural wealth of Babylonia offered a tempting prey to the hardy tribes who dwelt among the hills upon the western border of Elam, and the dread of the raider and mountaineer, experienced by the dweller in the plain, is expressed by Eannatum in his description of Elam as "the mountain that strikes terror."[35] That in their conflict with Eannatum the Elamites were, as usual, the aggressors, is clear from the words of the record upon his longer foundation-inscription--"by Eannatum was Elam broken in the head, Elam was driven back to his own land."[36] In other passages referring to the discomfiture of the Elamites, Eannatum adds the formula that "he heaped up burial-mounds," a phrase which would seem to imply that the enemy were only defeated with considerable loss.[37] It is not unlikely that we may fix the field of battle, upon which the forces of Elam were defeated, on the banks of the Asukhur Canal, which had been cut two generations before by Ur-Ninâ, Eannatum's grandfather; at least, the canal gives its name to a battlefield which is mentioned immediately before the name of Elam in one of the lists of conquests. It would thus seem that the Elamites were engaged in raiding the territory of Lagash when Eannatum fell upon them with his army and drove them northwards and across the Tigris.
