Cannon - online puzzles

A cannon (plural: cannon or cannons) 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 in the 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. The word cannon is derived from several languages, in which the original definition can usually be translated as tube, cane, or reed. In the modern era, the term cannon has fallen into decline, replaced by "guns" or "artillery" if not a more specific term such as "mortar" or "howitzer", except in the field of aerial warfare, where it is often used as shorthand for autocannon.

The earliest known depiction of cannon appeared in Song dynasty China as early as the 12th century, however solid archaeological and documentary evidence of cannon do not appear until the 13th century. In 1288 Yuan dynasty troops are recorded to have used hand cannons in combat, and the earliest extant cannon bearing a date of production comes from the same period. Evidence of cannon next appeared in Europe. By 1326 depictions of cannon had also appeared in Europe and almost immediately recorded usage of cannon began appearing. By the end of the 14th century cannon were widespread throughout Eurasia.
