The Battle of Arrapha took place in 616 BC during the Medo-Babylonian conquest of the Assyrian Empire. [1] Babylonian king Nabopolassar with the help of other rebellion forces succeeded by driving the Assyrians back to the Little Zab, near Arrapha - in doing so capturing many Assyrian armoury, horses, and chariots. [2] The next year, Cyaxares, king of the Medes went to battle the Assyrians and conquered the region around Arrapha in preparation for a great campaign against the Assyrians. [3]
