Chief Diwan under Shah Jahan
After his falling-out with Golconda and negotiated entry into Mughal service, Mir Jumla was received at court by Shah Jahan with unusual favour. The register records the moment: on "25th of the holy Ramadan Mir Jumla paid his respects to the Emperor at Delhi, and received the rank of 6,000 with 6,000 horse, and the high office of the chief Divan, and was granted a jewelled pen-case, five lacs of rupees in cash and other royal favours" (vol. II, p. 191). He went on to serve Aurangzib as viceroy of Bengal and led the invasion of Assam.
Death after Assam
The Assam campaign broke his health. Rains, disease and a Raja who would not be brought to battle forced a costly peace, and on the retreat toward Bengal he grew steadily worse, suffering, the register says, from asthma, palpitation and dropsy. The account is precise about where and when: "on the 2nd Ramadan in the beginning of 6th year, 1073 A.H. (10th April, 1663 A.D.) he died at a distance of two kos from Khidrpur" (vol. II, p. 204), before he could complete the march back to Dacca.
