Rockets
Today's rocket projectiles are not exactly new
inventions. About the time of artillery's beginning, the military
fireworker came into the business of providing pyrotechnic engines of
war; later, his job included the spectacular fireworks that were set off
in celebration of victory or peace.
Artillery manuals of very early date include chapters
on the manufacture and use of fireworks. But in making war rockets there
was no marked progress until the late eighteenth century. About 1780,
the British Army in India watched the Orientals use them; and within the
next quarter century William Congreve, who set about the task of
producing a rocket that would carry an incendiary or explosive charge as
far as 2 miles, had achieved such promising results that English boats
fired rocket salvos against Boulogne in 1806. The British Field Rocket
Brigade used rockets effectively at Leipzig in 1812—the first time they
appeared in European land warfare. They were used again 2 years later at
Waterloo. The warheads of such rockets were cast iron, filled with black
powder and fitted with percussion fuzes. They were fired from
trough-like launching stands, which were adjustable for elevation.
Rockets seem to have had a demoralizing effect upon
untrained troops, and perhaps their use by the British against raw
American levies at Bladenburg, in 1814, contributed to the rout of the
United States forces and the capture of Washington. They also helped to
inspire Francis Scott Key. Whether or not he understands the technical
characteristics of the rocket, every schoolboy remembers the "rocket's
red glare" of the National Anthem, wherein Key recorded his eyewitness
account of the bombardment of Fort McHenry. The U.S. Army in Mexico
(1846-48) included a rocket battery, and, indeed, war rockets were an
important part of artillery resources until the rapid progress of
gunnery in the latter 1800's made them obsolescent. |
