In 878 BC Ashurnasirpal II, the king of Assyria, conquered Suru, the main fortress of governor of Sukhu (Suhum), from the Babylonian state.[1] Although the Assyrians claimed a great victory, this claim is doubted due to subsequent revolts in the middle Euphrates region, and because the Assyrian army under Ashurnasirpal II was never again reported as attacking as far into Sukhu. The Assyrians reportedly captured a contingent of Babylonian cavalry during this battle. This is one of few battles reported during this time period concerning Babylonian military affairs.
