The mutiny, of which an account begins in the text, was crushed by the victory of 500 loyalists over 3,000 rebels, one factor of success being Bābur's defeat in single combat of five champions of his adversaries.[1334] The disturbance was not of long duration; Kābul was tranquil in Sha`bān (November) when Sl. Sa`īd Khān _Chaghatāī_, then 21, arrived there seeking his cousin's protection, after defeat by his brother Manṣūr at Almātū, escape from death, commanded by Shaibānī, in Farghāna, a winter journey through Qarā-tīgīn to Mīrzā Khān in Qilā'-i-ẓafar, refusal of an offer to put him in that feeble Mīrzā's place, and so on to Kābul, where he came a destitute fugitive and enjoyed a freedom from care never known by him before (f. 200_b_; T.R. p. 226). The year was fatal to his family and to Ḥaidar's; in it Shaibānī murdered Sl. Maḥmūd Khān and his six sons, Muḥammad Ḥusain Mīrzā and other Dūghlāt sulṯāns. 915 AH.-APRIL 21ST 1509 TO APRIL 11TH 1510 AD. In this year hostilities began between Shāh Ismā`īl _Ṣafawī_ and Muḥ. Shaibānī Khān _Aūzbeg_, news of which must have excited keen interest in Kābul. In it occurred also what was in itself a minor matter of a child's safety, but became of historical importance, namely, the beginning of personal acquaintance between Bābur and his sympathetic biographer Ḥaidar Mīrzā _Dūghlāt_. Ḥaidar, like Sa`īd, came a fugitive to the protection of a kinsman; he was then eleven, had been saved by servants from the death commanded by Shaibānī, conveyed to Mīrzā Khān in Badakhshān, thence sent for by Bābur to the greater security of Kābul (f. 11; Index _s.n._; T.R. p. 227). 916 AH.-APRIL 11TH 1510 TO MARCH 31ST 1510 AD. _a. News of the battle of Merv._ Over half of this year passed quietly in Kābul; Ramẓān (December) brought from Mīrzā Khān (Wāis) the stirring news that Ismā`īl had defeated Shaibānī near Merv.[1335] "It is not known," wrote the Mīrzā, "whether Shāhī Beg Khān has been killed or not. All the Aūzbegs have crossed the Amū. Amīr Aūrūs, who was in Qūndūz, has fled. About 20,000 Mughūls, who left the Aūzbeg at Merv, have come to Qūndūz. I have come there." He then invited Bābur to join him and with him to try for the recovery of their ancestral territories (T.R. p. 237). _b. Bābur's campaign in Transoxiana begun._ The Mīrzā's letter was brought over passes blocked by snow; Bābur, with all possible speed, took the one winter-route through Āb-dara, kept the Ramẓān Feast in Bāmīān, and reached Qūndūz in Shawwāl (Jan. 1511 AD.). Ḥaidar's detail about the Feast seems likely to have been recorded because he had read Bābur's own remark, made in Ramẓān 933 AH. (June 1527) that up to that date, when he kept it in Sīkrī, he had not since his eleventh year kept it twice in the same place (f. 330). _c. Mughūl affairs._
