Before the diary of 925 AH. (1519 AD.) takes up the broken thread of his autobiography, there is a _lacuna_ of narrative extending over nearly eleven years. The break was not intended, several references in the _Bābur-nāma_ shewing Bābur's purpose to describe events of the unchronicled years.[1332] Mr. Erskine, in the Leyden and Erskine _Memoirs_, carried Bābur's biography through the major _lacunæ_, but without firsthand help from the best sources, the _Habību's-siyar_ and _Tārīkh-i-rashīdī_. He had not the help of the first even in his _History of India_. M. de Courteille working as a translator only, made no attempt to fill the gaps. Bābur's biography has yet to be completed; much time is demanded by the task, not only in order to exhaust known sources and seek others further afield, but to weigh and balance the contradictory statements of writers deep-sundered in sympathy and outlook. To strike such a balance is essential when dealing with the events of 914 to 920 AH. because in those years Bābur had part in an embittered conflict between Sunni and Shī`a. What I offer below, as a stop-gap, is a mere summary of events, mainly based on material not used by Mr. Erskine, with a few comments prompted by acquaintance with Bāburiana. _USEFUL SOURCES_ Compared with what Bābur could have told of this most interesting period of his life, the yield of the sources is scant, a natural sequel from the fact that no one of them had his biography for its main theme, still less had his own action in crises of enforced ambiguity. Of all known sources the best are Khwānd-amīr's _Ḥabību's-siyar_ and Ḥaidar Mīrzā _Dūghlāt's Tārīkh-i-rashīdī_. The first was finished nominally in 930 AH. (1524-5 AD.), seven years therefore before Bābur's death, but it received much addition of matter concerning Bābur after its author went to Hindūstān in 934 AH. (f. 339). Its fourth part, a life of Shāh Ismā`īl _Ṣafawī_ is especially valuable for the years of this _lacuna_. Ḥaidar's book was finished under Humāyūn in 953 AH. (1547 AD.), when its author had reigned five years in Kashmīr. It is the most valuable of all the sources for those interested in Bābur himself, both because of Ḥaidar's excellence as a biographer, and through his close acquaintance with Bābur's family. From his eleventh to his thirteenth year he lived under Bābur's protection, followed this by 19 years service under Sa`īd Khān, the cousin of both, in Kāshghar, and after that Khān's death, went to Bābur's sons Kāmrān and Humāyūn in Hindūstān.
