Hand Cannon - Design and Features

Design and Features

The hand cannon was a simple weapon, effectively consisting of a barrel with some sort of handle, though it came in many different shapes and sizes. Although surviving examples are all completely constructed of metal, evidence suggests that many were attached to some kind of stock, usually wooden. Other examples show a simple metal extension from the barrel acting as the handle. In fact, not all hand cannons used metal at all in their construction, as some Chinese illustrations demonstrate bamboo tubes being used instead.

For firing, the hand cannon could be held in two hands while a helper applied the means of ignition. These could range from smoldering wood or coal, red-hot iron rods, to slow-burning matches. Alternatively, the hand cannon could be placed on a rest and held by one hand while the gunner applied the means of ignition himself. Projectiles used in these weapons were varied, with many utilizing a variety of different ammunition. Rocks or pebbles found on the ground could be fired from hand cannon, more sophisticated ammunition such iron or stone in the shape of balls and arrows could also be used.

Later hand cannons were made with a flash pan attached to the barrel, and a touch hole drilled through the side wall of the gun instead of the top of the barrel. The flash pan had a leather cover, and later on a hinged metal lid fitted, to keep the priming powder dry until the moment of firing and to prevent premature firing. These features were carried on over to subsequent firearms.

Due to the poor quality of powder that was often used in these weapons and their crude construction, they were not effective missile weapons, as early examples often lacked sufficient power to punch through light armour. All were inaccurate, due to the awkward handling as well as the aforementioned poor quality of the weapons. While the noise and flash may have had some psychological effect on the enemy, many early hand cannons were utilized in a minor capacity and so lacked battlefield presence.

The invention of corned powder, the slow match, and the serpentine around the mid-15th century led to much more effective firearms and eventually to increased adoption. It also prompted the development of the first matchlock firearms, which could be more effectively aimed and fired than hand cannon. Gradually, hand cannon became obsolete, although it found use in some locales up until the 20th century.
