A number of letters written during the years 1842-44 describe the uncertain political state in Lahore.Events leading to the Anglo Sikh war of 1845-46, and the details of military operations at Mudki, Baddoval, `Aliwal and Sabhraon are given (1846). They also give an account of Lal Singh`s administration and the rebellion in Kashmir which led to the treaty of Bharoval. A full account of the uprisings at Multan and Hazara and particulars of the military operations against Multan, besides the actions at Chelianvala and Gujrat are also provided (1848 and 1849).
