It thus happened that in the expedition which now followed, Asshur-bani-pal had a party which favored him in Elam itself.

Temin-Umman, however, aware of this internal weakness, made great efforts to compensate for it by the number of his foreign allies.
Two descendants of Merodach-Baladan, who had principalities upon the coast of the Persian Gulf, two mountain chiefs, one of them a blood-connection of the Assyrian crown, two sons of Belu-bagar, sheikh of the Gambulu, and several other inferior chieftains, are mentioned as bringing their troops to his assistance, and fighting in his cause against the Assyrians.

All, however, was in vain.

Asshur-bani-pal defeated the allies in several engagements, and finally took Temin-Umman prisoner, executed him, and exposed his head over one of the gates of Nineveh.

He then divided Elam between two of the sons of Urrtaki, Umman-ibi and Tammarit, establishing the former in Susa, and the latter at a town called Khidal in Eastern Susiana.
