I've just finished reading 'Soldier Sahibs' by Charles Allen which my library obtained on loan from the Hampshire County Council Military Collection in Aldershot. It deals in great detail with the history of our conquest of the Punjab, the two Sikh wars, and the reconquest of Delhi after the Mutiny, and with our relations with the Afghans during this period. In between the author, using quotes from the top Brits at the time (Lawrence, Nicholson etc), explains the culture, psychology and attitude of the Sikhs and the Afghans. From my armchair I would say it ought to be required reading for anyone about to be sent out to Afghanistan, particularly senior people, and anyone directing our efforts there from a desk in Whitehall. Yanks should read it too but some of the words are more than two syllables long.
