In 1853, Turkey declared war on Russia. After the Russian Navy destroyed a Turkish squadron in the Black Sea, Great Britain and France joined with Turkey. In September of the following year, the British landed on the Crimean Peninsula and set out, with the French and Turks, to take the Russian naval base at Sevastopol.
What followed was a tragicomedy of errors – failure of supply, failed communications, international rivalries. Conditions in the armies were terrible, and disease ate through their ranks. They finally did take Sevastopol a year later, after a ghastly assault. It was ugly business all around. Well over half a million soldiers lost their lives during the Crimean War.
