Book excerpt: 'We must all fight for Holy Russia!' declared the Russian officers at the outbreak of the Crimean War (1853-1856). Despite the immensity of the Russian forces that fought in this conflict, however, their dispersion over vast distances, along with poor roads and contrary weather, contributed to their defeat. Still, many regiments won much-deserved battle honours; from the navy emerged a number of heroes, including Admirals Kornilov, Nakhimov and Istomin. This book details the forces that served the Tsar in the defence of the Crimea, with chapters on Army organization, the Army of the Caucasus, the Imperial Navy, army life, tactics and Russian heroes.
