To carry hostilities into the heart of their country was a bold and even hazardous undertaking; it could be reached only by traversing miles of arid and rocky plains, exposed to the rays of a burning sun, vast extents of swamps and boggy pasture land, desolate wastes infested with serpents and scorpions, and a mountain range of blackish lava known as Khazu. It would have been folly to risk a march with the heavy Assyrian infantry in the face of such obstacles. Esarhaddon probably selected for the purpose a force composed of cavalry, chariots, and lightly equipped foot-soldiers, and despatched them with orders to reach the Jauf by forced marches through the Wady Hauran. The Arabs, who were totally unprepared for such a movement, had not time to collect their forces; eight of their chiefs were taken by surprise and killed one after another--among them Kisu of Khaldili, Agbaru of Ilpiati, Mansaku of Magalani,--and also some reigning queens. La, the King of Yadi, at first took refuge in the mountains, but afterwards gave himself up to the enemy, and journeyed as far as Nineveh to prostrate himself at Esarhaddon's feet, who restored to him his gods and his crown, on the usual condition of paying tribute. A vassal occupying a country so remote and so difficult of access could not be supposed to preserve an unbroken fidelity towards his suzerain, but he no longer ventured to plunder the caravans which passed through his territory, and that in reality was all that was expected of him. Esarhaddon thus pursued a prudent and unadventurous policy in the northern and eastern portions of his empire, maintaining a watchful attitude towards the Cimmerians and Scythians in the north, carrying on short defensive campaigns among the Medes in the east, preserving peace with Elam, and making occasional flying raids in the south, rather from the necessity for repressing troublesome border tribes than with any idea of permanent conquest.
