The Battle of Waterloo has been studied and dissected so extensively that one might assume little more on the subject could be discovered. Now historian Peter Hofschröer brings forward a long-repressed commentary written by Carl von Clausewitz, the author of On War. Clausewitz, the Western world's most renowned military theorist, participated in the Waterloo campaign as a senior staff officer in the Prussian army. His appraisal, offered here in an up-to-date and readable translation, criticized the Duke of Wellington's actions. Lord Liverpool sent his translation of the manuscript to Wellington, who pronounced it a "lying work." The translated commentary was quickly buried in Wellington's private papers, where it languished for a century and a half. Now published for the first time in English, Hofschröer brings Clausewitz's critique back into view with thorough annotation and contextual explanation. Peter Hofschröer, long recognized as a leading scholar of the Napoleonic Wars, shows how the Duke prevented the account's publication during his lifetime-a manipulation of history so successful that almost two centuries passed before Clausewitz's work reemerged, finally permitting a reappraisal of key events in the campaign. In addition to translating and annotating Clausewitz's critique, Hofschröer also includes an order of battle and an extensive bibliography.
