When he crossed the Persian border, he found himself received with a certain contemptuous pity. Still, female servants were sent to attend on the queen, and demonstrations were made in his favour. Arrived at the court of King Tahmâsp, however, the exiled monarch of India found himself by no means on a bed of roses. Even the gift of the greatest treasure he possessed, a huge diamond, did not ameliorate his situation; for Shâh Tahmâsp affected to despise the jewel, and is said to have sent it away disdainfully in a gift to the King of the Dekkan. But the whole history of this diamond, which has now disappeared, is a fine romance. It is said to have been the eye of Shiv-ji in some shrine, and to have passed into the possession of many conquerors, until it was given to Babar in recognition of chivalrous kindness and courtesy shown to them by the family of the Râjah of Chitore. Babar, who kept nothing for himself, gave the stone, "worth half the daily expenditure of the world," to his son. It is said to have weighed about 280 carats, and to have been of the purest water; it is also conjectured that it reappeared as the Great Moghul diamond which Tavernier describes as belonging to Shâh-jahân, and that possibly it is this very stone which, cleft and badly cut, still shines as the Koh-i-nur. It did not, anyhow, avail Humâyon much. More effective was his servile consent to wear the red cap of the Persian, and by this becoming a _khizil bash_, renounce his Sunni faith, and proclaim himself a Shiah. He did not do this without much pressure, and at the very last nearly broke bondage; but the promise of ten thousand horse wherewith to recover his kingdom was too tempting. With this force he attacked Kandahâr, where his brother Âskari still held little Akbar as a hostage; or, rather, had so held him until the attacking army loomed over the horizon, when, after some hesitation as to whether it would not be wiser to send the boy under honourable escort to his father, Âskari decided on obeying his brother Kamrân's orders, and despatched the little prisoner to Kâbul. The story of that inclement winter march across the hills, with its attempts at rescue and numberless adventures, would make a charming book for English children. After five months siege, Kandahâr surrendered, "Dearest Lady" having succeeded in obtaining a promise of pardon for Âskari from his brother. It was revoked, however, in an altogether indefensible manner, and Âskari was kept in chains for the next three years. This is so unlike Humâyon's usual conduct towards his brothers, that it gives colour to the assertion made by some authorities that Âskari's punishment was due to the discovery of a further offence.
