The Charge of the Light Brigade, Florence Nightingale—these are the enduring icons of the Crimean War. Less well-known is that this savage war (1853-1856) killed almost a million soldiers and countless civilians; that it enmeshed four great empires—the British, French, Turkish, and Russian—in a battle over religion as well as territory; that it fixed the fault lines between Russia and the West; that it set in motion the conflicts that would dominate the century to come.
