The story of Baykand’s resurrection is a curious one. It was a town of long-standing fame and a great centre of trade; and, during the siege, most of the heads of families were absent in China and other distant countries with their caravans. On their return they redeemed their wives and surviving relatives from the Arabs, and soon repeopled Baykand. Narshakhi justly remarks,[115] that it is the only town in history which, after undergoing a destruction, root and branch, was restored to its former prosperity by the same generation as saw its ruin. Tabari adds that the inhabitants agreed to pay a yearly tribute to the Arabs, and were guaranteed peace, under a written pact, by Kutayba. The conquest of Baykand was achieved by Kutayba in the autumn of the year of the Hijra, 87 (705). He then returned for the winter season to his headquarters at Merv. It was not till A.H. 88 (706) that Kutayba entered on a career of conquest. During his first two years of command he had achieved little towards the extension of the Caliph’s authority in Central Asia. His predecessors had already carried their arms as far as the city of Bokhārā, while his own had never extended far beyond the frontier of that kingdom. The destruction of Baykand was, however, a feat of no mean value, as, quite apart from the immense booty which fell into the victor’s hands, the position of the town rendered it “the south-western gate of Transoxiana,”[116] and hence its importance to the Arabs as a basis for further encroachments. The immediate objects of Kutayba’s attacks were, according to Tabari,[117] Numushkat and Rāmtīna, which obtained peace on condition of paying a yearly tribute.
