He marched from Peshawar to Herāt with three hundred elephants, a tent embroidered with pearls, and the famous Peacock Throne, ravished from the Hall of Private Audience at Delhi.[463] Thence he travelled to Karki on the Oxus frontier of Bokhārā, where he was met by Rahīm Bi with presents and supplies for his locust-horde of followers. Thence he fared to Charjūy, and traversed the mighty river by a bridge which he threw across it in three days. Leaving half his army to protect the priceless baggage, he moved on to Karakūl, a fortress one day’s march from the capital. Here he was met by Abū-l-Fayz, attended by his nobles, courtiers, and clergy, bringing a present of beautiful Arab horses. The titular sovereign of Bokhārā presented himself as a suppliant, but was given a seat by Nādir Shāh. Clad in a robe of state and crowned, the imperious guest carried his complaisance so far as to address his host as “Shāh.” But further honours were in store for the obsequious Abū-l-Fayz. Nādir deigned to accept his lovely daughter as a wife, bestowing her sister, at the same time, on his nephew. He created Mohammad Rahīm Bi, to whose influence he owed his reception, Khān, and gave him command of 6000 chosen troops levied in Turkestān. Having thus brought Bokhārā to heel, Nādir Shāh turned his attention to Khiva. He sent an envoy to Ilbars Khān, demanding his instant submission. The Khivan was a man of ungovernable temper, and his reply was to put to death those who held out to him the olive branch. This breach of the usages of Islām sealed his fate. He was attacked by Nādir Shāh with an overwhelming force, and closely invested in his fortress of Khanka. After undergoing a cannonade for three days, the proud Ilbars was forced to throw himself upon the mercy of a man whose fearful butchery of the population of Delhi showed that he was insensible of the softer feelings; and against him pleaded the children of the slaughtered envoys, whose blood cried aloud for vengeance. He was put to death, and twenty-one of his principal officers shared his fate.[464] Having thus rid himself of a perpetual thorn in his side, Nādir Shāh returned to Charjūy, whence he sent back to her father the young princess whom he had lately wedded. He then returned to Khorāsān by way of Merv, and fell a victim to a conspiracy among his followers, provoked to extremities by his insane cruelty, A.H. 1160 (1747).
