For these were a people who emerged from the confines of China, and attacked the cities of Turkestan, like Kashghar and Balasaghun, and thence advanced on the cities of Transoxiana . . . and of them one division then passed on into Khurasan, until they had made an end of taking possession, and destroying, and slaying, and plundering, and thence passing on to Ray, Hamadan and the Highlands, and the cities contained therein, even to the limits of Iraq, whence they marched on the towns of Adharbayjan and Arraniyya, destroying them and slaying most of their inhabitants, of whom none escaped save a small remnant . . . And thence they made their way to the lands of Qipchaq, who are the most numerous of the Turks, and slew all such as withstood them, while the survivors fled to the fords and mountain-tops, and abandoned their country, which these Tatars overran. All this they did in the briefest space of time, remaining only for so long as their march required and no more.
