The Battle of the Great Redan was a major battle during the Crimean War, fought between British forces against Russia on 18 June and 8 September 1855 as a part of the Siege of Sevastopol. The French army successfully stormed the Malakoff redoubt, whereas a simultaneous British attack on the Great Redan to the south of the Malakoff was repulsed. Contemporary commentators have suggested that, although the Redan became so important to the Victorians, it was probably not vital to the taking of Sevastopol. The fort at Malakhov was much more important and it was in the French sphere of influence. When the French stormed it after an eleven-month siege that the final, the British attack on the Redan became somewhat unnecessary.

The siege of Sevastopol lasted from October 1854 until September 1855, during the Crimean War. The allies landed at Eupatoria on 14 September 1854, intending to make a triumphal march to Sevastopol, the capital of the Crimea, with 50,000 men. Major battles along the way were Alma, Balaklava, Inkerman, Tchernaya, Redan, and, finally, Malakoff. During the siege, the allied navy undertook six bombardments of the capital, on 17 October 1854; and on 9 April, 6 June, 17 June, 17 August, and 5 September 1855.
