The Assyrian involvement in Syria continued under the command of king Sulmanu-ašared I and precipitated a crisis with Ḫatti. The Hittites considered Assyrian involvement to be a clear attack on the frontiers of their empire and went into battle under their king: Tudḫalia IV, Ḫattusili's son and successor. This led to a major battle which is known today as the Battle of Niḫriya.
