They continued their march and stormed Bukhara, a town of academies, of men of learning; a town of villas and gardens. After a few days’ defiance by a garrison, 20,000 strong, the gates of the city were flung open. The city was full of Mongol soldiers who made stables of libraries and litter of the leaves of the Qur'an. They feasted and held high revel. Musicians and singers were summoned, while the nobles of the city were made to groom the horses. The most precious containers of the Qur'an were used as mangers, while the sacred books were flung anywhere on the ground and trodden under foot. According to Juwaini, one man escaped from Bukhara after its capture to Khurasan. Questioned about the fate of the city he replied, ‘They came, they sapped, they burnt, they slew, they plundered and they departed.’ Men of understanding who heard this description were all agreed that in the Persian language there could be nothing more concise than this speech. The populace was inconsolable; the wise men said it was necessary to suffer without murmuring, since it was the wind of God’s anger blowing upon them. The great city, which in the morning was one of the most beautiful cities in all Asia, was, on that fatal evening, a heap of cinder and ruin. The seat of arts and science where Avicenna once studied philosophy presented a dreary picture of desolation. Chingiz is reported to have described himself in a speech as ‘the scourge of God sent to men as a punishment for their sins.’ Ibn-ul-Athir, a contemporary authority, shudders at the narration of these horrors and wishes his mother had not borne him!
From Bukhara, Chingiz followed the fertile valley of Zarafshan to Samarkand which was strongly garrisoned. Here 30,000 artificers were distributed among the Mongols while the rest of the inhabitants were mostly massacred and the city was set on fire. ‘Samarkand,’ says Abul-Fida, ‘where the sky is perpetually clear, has fine stone buildings and public marketing places, and has considerable commerce with Great Tartary, India and Persia, whence all sorts of merchandise are brought; and this city furnishes Hindustan with the best fruit, green and dried. The silk paper made here is the finest in the world. There is a famous academy of sciences.’ All this prosperity vanished with the visit of the Mongols, never to return.
