In “The Cossacks,” Tolstoy tells the story of Olenin, a cultured Russian whose experiences among the Cossack warriors of Central Asia leave him searching for a more authentic life. “The Sevastopol Sketches” bring into stark relief the realities of military life during the Crimean War. And “Hadji Murat” paints a portrait of a great leader torn apart by divided loyalties. In writing about individuals and societies in conflict, Tolstoy has penned some of the most brilliant stories about the nature of war.
