Capture of the Malakoff Redoubt

Assault on Malakoff redoubt constituted most decisive military operation of Sevastopol siege. Commanded by Mac Mahon, French attack seized nerve center of Russian defensive system. While British troops failed to take Great Redan, French stormed redoubt with sappers, trenches, and intense artillery bombardment. Capture of Malakoff triggered immediate Russian evacuation of Sevastopol, ending 11-month siege.

Since September 1854 Allies besieged Sevastopol fortress, main military port of Russian Black Sea fleet. After long trench campaign French forces identified Malakoff redoubt as key point of Russian dispositions. Marshal Pélissier, Canrobert's successor, decided to mount main assault on this redoubt. Attack was scheduled simultaneously with British offensive on Great Redan. French success, contrasting with British failure, highlighted effectiveness of planning and Mac Mahon's commitment.

French used approach trenches, intense artillery preparation, and carefully distributed assault columns. Attack was led at dawn under heavy Russian fire. Mac Mahon at head of troops seized redoubt after fierce hand-to-hand fighting. Russians attempted several desperate counterattacks but were repulsed. Mac Mahon is said to have pronounced famous phrase "Here I am, here I stay" signifying he would hold conquered position at all costs.

Capture of Malakoff triggered immediate fall of Sevastopol. Russians, unable to retake redoubt, evacuated city following night. This major victory ended principal land operations in Crimea and opened way to armistice signed in 1856. Symbolically it consolidated French military prestige under Napoleon III and propelled Mac Mahon to rank of national hero. It also marked end of Russian naval power in Black Sea, in accordance with future Treaty of Paris terms.
