While the French conquered the Malakoff redoubt, the British troops launched a simultaneous attack on the Redan redoubt, which the Russians were able to repel. Today this attack is viewed as being comparatively insignificant because the Malakoff redoubt was considerably more important and its conquest by the French decided the war.
