The Battle of Sevastopol was a significant conflict during the Crimean War, fought from 1854 to 1855. It involved an alliance of British, French, and Ottoman forces besieging the Russian port city of Sevastopol, which was a key naval base for the Russian Empire. The battle aimed to weaken Russian naval power in the Black Sea. The siege lasted for nearly a year, marked by intense fighting and heavy casualties on both sides. Ultimately, the allied forces captured Sevastopol in September 1855, leading to a shift in the balance of power in the region and contributing to the eventual end of the Crimean War.
