This notion sadly reinforces an ethnocentric view that non-Western peoples somehow stand outside history, and that nothing ever really changes for them. Like many specialists in US and European history glancing at the whole world, Pratt proceeds from inattention and/or ignorance in generalizing, even stereotyping, on topics beyond his expertise. Such an assertion plainly overlooks many examples of the decisive character of warfare in Asia and Africa, with or without European participation---the conquests of Jinghiz Khan and his successors, Japan's conquest of Singapore in 1942, Ethiopia's 1896 triumph over Italy at Adowa, the effects of slaving wars in Africa, etc.
Pratt renders persuasive accounts of decisive Western battles in clear, lively prose. But misjudging the miltary experience of the rest of the world weakens his case, which through fuller research could be extended fruitfully to encompass the globe. The whole subject requires further examination; there's plenty of work for numerous scholars to tackle, and this should ultimately show that Pratt's thesis is indeed applicable on a worldwide scale. Ultimately, military historians have moved beyond the Alexandrian/Napoleonic conception of decisive battlefield victory to an appreciation of the total process of war in winning conflicts.
For more on the nonhistorical »nature« of non-Western societies and the processes which integrated them into a European-dominated global system, read Eric Wolf, »Europe and the People Without History« and Chinweizu, »The West and the Rest of Us.« For Asians' and Africans' encounter with Western military technology, strategy and tactics, see Geoffrey Parker, »The Military Revolution« and Daniel Headrick, »The Tools of Empire.« M. Saul & P. Royer, »West African Challenge To Empire« & J. Thornton, »Warfare in Atlantic Africa« show how African wars were actually fought.
The key to this book is the phrase »Changed History« in the title. In his introduction, Pratt takes pains to distinguish his list of battles from those of the progenitor of the genre, Sir Edward Creasy, whose »Fifteen Decisive Battles« provided the inspiration for Pratt's work. Pratt notes that so many famous Western battles (e.g. Hastings or Tours) actually played a defensive or reinforcing role in history rather than »changing history.« This insight leads Pratt to choose some battles that many might view as eccentric (e.g. Beneventum, the original »Pyrrhic victory«, rather than, say, Zama, which ended the Second Punic War). It is Pratt's rationale for these choices, expressed in clear, crisp prose, that makes this book so valuable for younger readers in need of a boost in their motivation to read history.
