MOUTH OF FIRE

                           History cannon 26 | 015895

  This cannon was brought from Spain probably in the colonization period of the area that later became Paraguay. Later, it was captured by the Brazilian armed forces during the War of Paraguay that lasted from 1865 to 1870.

 

  A cannon is a type of gun classified as artillery that launches
a projectile using propellant. In the past, gunpowder was the primary propellant before the invention of smokeless powder during the late 19th century. Cannon vary in caliber, range, mobility, rate of fire, angle of fire, and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield.

 

  There were essentially four different types of artillery and four different classifications. The types were guns, howitzers, mortars, and columbiads. The classifications were seacoast, siege and garrison, field, and mountain. A short definition of each follows:
 

  • Guns - heavy weapons with long barrels to batter fortifications with shot at long range.

  • Howitzers - shorter barreled guns with "chambers" in the bores for smaller powder charges. They were designed to fire shells at higher elevations over less range.

  • Mortars - short chambered pieces used for lobbing shells
    at great elevation into the fortifications of the enemy.

  • Columbiads - long-barreled weapons combining the features
    of all three of the above, and were the heaviest pieces in use.

  • Seacoast - heaviest types of weapons that were mounted
    in permanent fortifications on the seaboard.

  • Siege and garrison - used to attack or defend fortifications
    and field works.

  • Field - light artillery, more maneuverable than garrison guns, could be taken on campaign with troops in active operations.

  • Mountain - used in rough country where there were poor roads. Could be disassembled and carried on the backs of mules over rugged terrain.

Curiosity: Bird cannon is a sound-emitting device that frightens and disorients birds in airports.  A typical cannon is powered by
a five-gallon propane tank and emits blasts at 20-minute intervals. This prevents accidents.
