I was fortunate a while back to pick up a copy of William Dalrymple's "The Last Mughal" on kindle for the princely sum of 99p. I've just finished reading it and can not recommend it highly enough to anyone interested in the Indian Mutiny. I nearly quit at the start, as in the preface Dalrymple comes across as a rather arrogant piece of work, acting as though he is the only historian to have ever carried out original research. He then proceeded to worsen my opinion of him by appearing initially to be totally pro Indian and utterly anti British. fortunately I persevered and it paid dividends big time. He uses a lot of previous unused material not only from the Indian point of view but also the British. Although he does not concentrate on the fine details of the military side, he still produces enough new information to fill in some obvious gaps(he identifies brigades of mutineers and shows how the brigades remains together and acted as independent cohesive units during the seige). Where he excels is at the portrayal of life inside Delhi during the siege for the inhabitants of Delhi, who in most cases suffered the extortion and looting of first the mutineers and then the avenging British forces. He also followed the aftermath of the capture of Delhi and the British occupation and the trial of the last Mughal PaShah.
It did leave me wiser and more than a bit uncomfortable about how our troops and senior officers had handed out retribution on a vast scale to in many instances totally innocent individuals.
Based on the quality of this book I will certainly be keeping an eye out for his other in particular-"White Mughals", which is about the British officers and officials who become "indianised" in the late 18th and early 19th centuries.
