The Castelo de São Jorge
The Castelo de São Jorge in Lisbon displays a breech loading Field Falcon dating to the 14th century. The display there states: This piece is representative of a whole family of pyrobalistic guns (falcons and falconets). They had a small bore, a long barrel, and were very versatile. Falcons and falconets appear in the end of the 14th Century and are built much like a wooden barrel (hence the name "gun barrel") using forged steel blades held together by reinforcing rings. Their versatility is demonstrated by the number of carriages we could find them in: • Field carriage - this was designed to move swiftly with the rest of the troops providing close fire support. • Siege carriage - designed to keep the falcon as still as possible in order to repeatedly hit the same spot on the wall to bring it down. • Naval carriage - when on board a ship it was often mounted on a sort of "crib" (and thus sometimes called a "berco" - Portuguese for crib), used mainly for close quarters fire support in boarding actions. Also of note is the fact that this is a breech loading gun and not a muzzle loading one. Breech loading comes to being very early in cannon development; it had a number of advantages such as fast fire rate, easier loading operation etc. However mechanical and metallurgical technology were not sufficiently developed so these guns suffered from poor joints between the movable chamber and the barrel, and a part of the deflagration gasses vented from the joint reducing power and range. By late 15th Century breech loading started to fall into disuse due to new smelting technologies that allowed better muzzle loading guns. == Gallery ==
