Prior to the battle, Sennacherib had sacked a number of Elamite settlements in 694 BC in an attempt to assert his authority over the region. Despite this, the Elamites, with their Chaldean allies from Babylon, managed to raise an army and met the Assyrian forces of Sennacherib in 693 BC at the Diyala River. According to the Assyrian account of the battle, the Elamites were heavily defeated.
