Edward Creasy&rsquo;s 1851 military analysis of fifteen world battles is a classic of its genre. Appearing between Clausewitz&rsquo;s <i>On War</i> (1832) and Ardant Du Picq&rsquo;s <i>Battle Studies</i> (composed c.1870), <i><b>The Fifteen Decisive Battles of the World: From Marathon to Waterloo</b></i> is essential reading for military scientists and historians.
