The next information we obtain is, that the Chingiz Khan, having determined to invade the dominions of the Khwarazmi Sultan, when making his preparations for the march, considered it advisable, before setting out, to leave no enemies in his rear; and, as Koshluk, the Naeman, and Tuk-Tughan, the Makrit, still remained, and their whereabouts was in the vicinity of his route towards the west, he deemed it necessary to reduce them first, and so the Nu-yin, Jabah [Yamah], was sent with a large army against Koshluk and Juji Ughlan, the Chingiz Khan’s son, at the head of another army, against the Makrits under Tuk-Tughan.
