Of these campaigns we know that the first conquest of Gankhar took place in Dungi's thirty-fourth year, and that of Simuru in the year that followed. The latter district does not appear to have submitted tamely to annexation, for in his thirty-sixth year Dungi found it necessary to send a fresh expedition for its reconquest. In the following year he followed up these successes by the conquest of Kharshi and Khumurti. Gankhar and Simuru were probably situated in the mountainous districts to the east of the Tigris, around the upper course of the Diyala, in the neighbourhood of Lulubu; for the four countries Urbillu, Simuru, Lulubu, and Gankhar formed the object of a single expedition undertaken by Dungi in his fifty-fifth year.[12] Kharshi, or Kharishi, appears to have also lain in the region to the east of the Tigris.[13] These victories doubtless led to the submission of other districts, for in his fortieth year Dungi married one of his daughters to the patesi of Anshan, among the most important of Elamite states. The warlike character of the Elamites is attested by the difficulty Dungi experienced in retaining control over these districts, after they had been incorporated in his empire. For in the forty-first year of his reign he was obliged to undertake the reconquest of Gankhar, and to send a third expedition there two years later; in the forty-third year he subdued Simuru for the third time, while in the forty-fourth year Anshan itself revolted and had to be regained by force of arms.
