This fortress was besieged by the allied French and British armies, under Marshal St. Arnaud and Lord Raglan, September 28, 1854. It was defended by a large force of Russians, under Prince Mentschikoff, with General Todleben as his principal engineer officer. The besiegers were too few for a complete investment, and though the harbour was closed by the British fleet, under Sir Edmund Lyons, the Russians were throughout the siege enabled to obtain reinforcements and provisions from the north side. The batteries opened on October 17, and from that time till September 8, 1855, the town was more or less continuously bombarded. On that day the Malakoff, an important part of the southern defences, was stormed by the French, and the place became untenable, the allies entering it unopposed on the following day. The Russians, during the later days of the bombardment, are said to have lost as many as 3,000 men a day.

Secessionville (American Civil War).

Secunderbagh (Indian Mutiny).

Fought November 16, 1857, during the second relief of Lucknow by Sir Colin Campbell. The Secunderbagh, a walled enclosure of strong masonry, held by a large body of rebels, was, after a bombardment of about an hour and a half, taken by storm by the 93rd Highlanders and the 4th Punjabis, with very heavy loss to the enemy, over 2,000 dead bodies being afterwards carried out of the enclosure.

Sedan (Franco-German War).

This battle, the most decisive of the war, was fought September 1, 1870, The French, under Marshal Macmahon, who was wounded early in the action, were driven from all their positions by the Germans, under the King of Prussia, and compelled to retire into Sedan, where they laid down their arms. The Emperor Napoleon III was among the prisoners, and one of the results of the surrender was his dethronement and the proclamation of a republic in Paris. The battle is remarkable for the charge of the Chasseurs d'Afrique, under General Margueritte, in the neighbourhood of Floing. The brigade was cut to pieces and the general killed. The Germans lost in the action 460 officers and 8,500 men; the French 3,000 killed, 14,000 wounded, and 21,000 prisoners, while 83,000 subsequently surrendered in Sedan. The Germans took 419 guns, 139 fortress guns and 66,000 rifles.
