In the Times Literary Supplement, Michael Howard is so impressed with Simpson’s book that he goes out on a limb to recommend it:
Some four decades ago, the TLS sent me a book to review by a young lecturer at Sandhurst entitled The Face of Battle. It impressed me so much that I described it as “one of the best half-dozen books on warfare to have appeared since the Second World War”. I wondered at the time if I had made a total fool of myself, but I need not have worried. The author, the late Sir John Keegan, proved to be one of the greatest military historians of his generation. It would be rash to put my money on such a dark horse again, but I shall. Emile Simpson’s War From the Ground Up is a work of such importance that it should be compulsory reading at every level in the military; from the most recently enlisted cadet to the Chief of the Defence Staff and, even more important, the members of the National Security Council who guide him.
Emile Simpson does not presume to show us how to conduct war, but he tells us how to think about it. He saw service in Afghanistan as a young officer in the Gurkhas, and his thinking is solidly rooted in that experience. Like Clausewitz 200 years earlier, Simpson found himself caught up in a campaign for whose conduct nothing in his training had prepared him; and like Clausewitz he realized that to understand why this was so he had to analyse the whole nature of war, from the top down as well as from the ground up. Afghanistan, he concluded, was only an extreme example of the transformation that war has undergone during his lifetime; and that itself is due to the transformation of the societies that fight it.

It is impossible to summarize Emile Simpson’s ideas without distorting them. His own style is so muscular and aphoristic that he can concentrate complex arguments into memorable sentences that will have a life of their own. His familiarity with the work of Aristotle and the history of the English Reformation enables him to explain the requirements of a strategic narrative as effectively as his experiences in Afghanistan illuminate his understanding of the relationship between operational requirements and political objectives. In short (and here I shall really go overboard) War From the Ground Up deserves to be seen as a coda to Clausewitz’s On War. But it has the advantage of being considerably shorter.
