Gentlemen, may I draw your attention to Frontier and Overseas Expeditions from India, Indian Army Intelligence Branch, 7 vols, 1983 Indian reprint, which piece of staff work gives very detailed accounts of all sorts of ops in and around India. An excellent source for researching your forebears' service either in the Indian Army or in attached British Army units. I used this to try and make sense of the Jowaki expedition of the late 1870s and found it enormously helpful, particularly in illuminating which units were in which column at which time, and what they were doing. In that particular case we were duffing the Jowaki Afridis at a cost far exceeding the savings to be made from cutting their leader's baksheesh, which had annoyed him to the point of cutting the Government's telephone and closing the Kohat Pass. Nowadays it takes some imagination to visualise a Victorian column on the march at 2 mph (max for camels), stretching for miles and miles with its menagerie of elephants, bullocks, mules, horses, camels and camp followers. Vols available in UK via inter-library lending.
