This unification of the Orient was accomplished only at a fearful cost. The records of Assyria are full of terrible deeds--of towns and cities without number given to the flames, of the devastation of fertile fields and orchards, of the slaughter of men, women, and children, of the enslavement of entire nations. Assyrian monarchs, in numerous inscriptions, boast of the wreck and ruin they brought to many flourishing lands. [Illustration: AN ASSYRIAN From a Nineveh bas-relief. The original is colored.] SARGON II, 722-705 B.C. The treatment of conquered peoples by the Assyrian rulers is well illustrated by their dealings with the Hebrews. One of the mightiest monarchs was an usurper, who ascended the throne as Sargon II. Shortly after his succession he turned his attention to the kingdom of Israel, which had revolted. Sargon in punishment took its capital city of Samaria (722 B.C.) and led away many thousands of the leading citizens into a lifelong captivity in distant Assyria. The Ten Tribes mingled with the population of that region and henceforth disappeared from history. [Illustration: ANCIENT ORIENTAL EMPIRES Map, THE ASSYRIAN EMPIRE about 660 B.C.

His name is familiar from the many references to him in Old Testament writings. An inscription by Sennacherib describes an expedition against Hezekiah, king of Judea, who was shut up "like a caged bird in his royal city of Jerusalem." Sennacherib, however, did not capture the place. His troops were swept away by a pestilence. The ancient Hebrew writer conceives it as the visitation of a destroying angel: "It came to pass that night that the angel of Jehovah went forth, and smote in the camp of the Assyrians an hundred fourscore and five thousand; and when men arose early in the morning, behold, these were all dead bodies." [11] So Sennacherib departed, and returned with a shattered army to Nineveh, his capital.

The subject races were attached to their oppressive masters by no ties save those of force. When Assyria grew exhausted by its career of conquest, they were quick to strike a blow for freedom. By the middle of the seventh century Egypt had secured her independence, and many other provinces were ready to revolt. Meanwhile, beyond the eastern mountains, the Medes were gathering ominously on the Assyrian frontier. The storm broke when the Median monarch, in alliance with the king of Babylon, moved upon Nineveh and captured it. The city was utterly destroyed.
