Meanwhile Bāber and his Persian auxiliaries were marching in the direction of Samarkand, causing great alarm among the Uzbegs. On reaching Ghujduvān[442] they encountered Jānībeg Sultan,[443] who had thrown himself into the fort. A fierce battle ensued, which is vividly described by Mīrzā Haydar in the following words: “The Uzbeg Sultans entered the fort on the same night on which the Turkomans and Bāber, who were encamped before the place, were busy preparing their siege implements. At dawn they arranged their forces in the midst of the suburbs, and stood facing the enemy. On the other side, too, preparations were made for a fight. Since the Uzbegs were in the suburbs, the field of battle was a narrow one. The Uzbeg infantry began to pour forth a shower of arrows from every quarter, so that soon the grip of Islām wrenched aside the hands of heresy and unbelief, and victory declared for the true faith.[444] The victorious breezes of Islām overturned the banners of the schismatics. The Turkomans were so completely routed that most of them perished on the field; all the wounds that had been effected by the swords at Karshī were now sewn up by the arrow-stitches of vengeance. They sent Mīr Najm and all the Turkoman Amīrs to hell; and the emperor retired, broken and crestfallen, to Hisār.” Bāber now determined on relinquishing his designs on Transoxiana, and, returning to Kābul, he prepared for an easier conquest--that of Hindustān. On gaining possession of Transoxiana, the Shaybānides divided it into a number of appanages, the eldest Sultan usually assuming the leadership of the rest. His name alone was read in the public prayers throughout the whole empire, and appeared on the coins of all the states which composed it. For nearly ninety-nine years did the Shaybānīs, that is, the descendants of Abū-l-Khayr Khān,[445] rule in Transoxiana. M. Veliaminof-Zernof was the first to elucidate the complications in their system of government during the sixteenth century.[446] In his article on the coins of Bokhārā and Khiva, above quoted, he published a list of the chief Khāns, whom he calls the _Khākāns_, of the Shaybānīs, and also a genealogical table showing their descent from Abū-l-Khayr Khān.[447] The separate appanages passed from father to son, and thus the residence of the Khākān, or chief Khān, was continually changing from one city to another. Thus Bokhārā lost its proud position as capital of Transoxiana, and took rank with other towns as the headquarters of successive chiefs.[448]
