The Battle of Balaclava, fought on 25 October 1854 during the Crimean War, was part of the Siege of Sevastopol, an Allied attempt to capture the port and fortress of Sevastopol, Russia's principal naval base on the Black Sea. The engagement followed the earlier Allied victory in September at the Battle of the Alma, where the Russian General Menshikov had positioned his army in an attempt to stop the Allies progressing south towards their strategic goal. Alma was the first major encounter fought in the Crimean Peninsula since the Allied landings at Kalamita Bay on 14 September, and was a clear battlefield success; but a tardy pursuit by the Allies failed to gain a decisive victory, allowing the Russians to regroup, recover and prepare their defence.
The Russians split their forces. Defending within the allied siege lines was primarily the Navy manning the considerable static defenses of the city and threatening the allies from without was the mobile Army under General Menshikov.
The Allies decided against a slow assault on Sevastopol and instead prepared for a protracted siege.
