Bomarsund. A strong fortress on one of the Aland isles in the Baltic Sea, taken by Sir Charles Napier, commander of the Baltic expedition, aided by the French military contingent under Gen. Baraguay d’Hilliers, August 16, 1854. The governor Bodisco and the garrison, about 2000 men, became prisoners, and the fortifications were destroyed.

Bomb. A hollow ball or shell of cast iron filled with explosive materials, and furnished with a fuze, which being ignited when the missile is discharged from a mortar or howitzer, burns during its flight, and causes it to explode with destructive violence when it falls. They are now commonly called shells.

Bombard. An ancient piece of ordnance, very short, thick, and wide at the bore. Some of the bombards used in the 15th century propelled stones weighing from 200 to 500 pounds each.

Bombard. To assault a town or fortress by projecting into it shells, etc., from mortars, in order to set fire to and destroy the houses, magazines, and other buildings.

Bombardelle (Fr.). A small bombard which was used in ancient times. In 1830, one was disinterred near Laon, France; it is the opinion of some that this bombardelle was manufactured during the reign of Charles VII., from 1436-40.

Bombardier. Is an artilleryman versed in that department of arms which relates especially to bombs and shells, mortars and howitzers, grenades and fuzes. In some foreign armies, the bombardiers form a separate corps. In the British service a bombardier is a non-commissioned grade in the artillery below that of corporal.

Bombardment. Is an attack upon a fortress or fortified town by means of shells, red-hot shot, carcasses, rockets, etc., to burn and destroy the buildings, and kill the inhabitants, and by this means compel its surrender. A bombardment requires little engineering skill; whereas a regular siege requires the aid of engineers to direct the attack against fortifications, guns, and soldiery, leaving the inhabitants and buildings untouched. It is generally regarded by military engineers as a cruel operation, and in modern times is mostly adopted as an adjunct to a siege. The stores required for a vigorous bombardment are immense. Thus, in 1759, Rodney threw 20,000 shells and carcasses into Havre; in 1792, the Duke of Saxe Teschen threw 36,000 shot and shell into Lille in 140 hours; in 1795, Pichegru threw 8000 shells into Mannheim in 16 hours; and in 1807, the English threw 11,000 shot and shell into Copenhagen in three days. Of the bombardments recorded in history may be mentioned that of Algiers by Duquesne in 1682-83, by the Venetians in 1784, and by the English in 1816; of Genoa in 1684; of Tripoli in 1685, 1728, and 1747; of Barcelona in 1691; of Brussels in 1694; of Toulon by the English in 1707; of Prague in 1744, 1759, and 1848; the bombardment of Lille by the Austrians in 1792; of Le Quesnoy, Breda, Lille, Lyons, Maestricht, and Mayence in 1793; of Menin, Valenciennes, and Ostend in 1794; of Copenhagen by the English in 1807; of Glogau, Breslau, and Schweidnitz by the French in 1806-7; of Saragossa by the French in 1808; of Flushing by the English in 1809; of Antwerp in 1832; of St. Jean d’Ulloa by the French in 1838; of Beyrout and St. Jean d’Acre by the English in 1840; of Barcelona by Espartero in 1842; of Mogador by the French in 1844; and of Odessa by the English and French fleets in 1854. Vera Cruz was bombarded by Gen. Scott for three days before its surrender, March 27, 1847. During the civil war recourse was had several times to this method of reducing fortified places. Among the most noted were the bombardment by Admiral Farragut for six days, April 18, 1862, of Forts Jackson and St. Philip (after which they surrendered); the bombardment of Fort Pulaski, Ga., by Gen. Gillmore, in April, 1862; the first bombardment of Fort Sumter in August, 1863, which effectually disabled the fort for immediate defense of Charleston harbor, although the works remained in the possession of the Confederates; and the second bombardment, which took place in October following, leaving the place in ruins. During the Franco-German war Strasburg was bombarded by the Prussians on August 18, 1870, and after an immense number of shells were thrown into it with ruinous effect the city surrendered on September 27. During the siege of Paris it was estimated that for two weeks in January, 1871, about 500 shells a day were thrown into the city, to the great destruction of life and property.

Bomb-chest. A chest filled with bombs, or only with gunpowder, placed under ground, to cause destruction by its explosion.

Bomb-proof. A term applied to military structures of such immense thickness and strength that bombs cannot penetrate them.

Bomb-shell. A hollow globe of iron, filled with powder, and thrown from a mortar; a bomb.
