This cannon ball formed the basis of a discussion with artillerist Peter Webster and historical society members in 2011. The following ideas were put forward. It was approximately 5 inches in diameter and weighed 10lb, Such cannon balls were used in an 18 calibre cannon, which were used only on ships. (12 calibre guns were field artillery). Australia was behind England in its artillery use and used hand me downs. In the 1800's Australia did an audit of artillery and cleared out those no longer in use. By the time of the 1830's 18lb cannons were largely obsolete and removed from service Australia used 18 calibre cannons in Northern Australia at Port Essington and Fort Dundas (Melville Island) Perhaps this cannon ball has no real connection with Australia and came as ballast from some other country.This is one of the more interesting items in our collection and there has been much conjecture over the years as to the story of how it ended up in Warrnambool. In that way it has built its own mystery and provenanceRound metal ball measuring 5 inches in diameter, weighing 10lb.

This deck cannon is believed to be a replica Carronade as it has no foundry mark, year of manufacture, proof marks or weight of carronade on it. However, its design matches the design of Carronades used in the early to mid 19th century. History: The carronade was designed as a short-range naval weapon with a low muzzle velocity for merchant ships, but it also found a niche role on warships. It was produced by the Carron iron works and was at first sold as a complete system with the gun, mounting, and shot altogether. Carronades initially became popular on British merchant ships during the American Revolutionary War. A lightweight gun that needed only a small gun crew and was devastating at short range was well suited to defending merchant ships against French and American privateers.   Its invention is variously attributed to Lieutenant General Robert Melville in 1759, or to Charles Gascoigne, manager of the Carron Company from 1769 to 1779. In its early years, the weapon was sometimes called a "mellvinade" or a "gasconade". The carronade can be seen as the culmination of a development of naval guns reducing the barrel length and thereby the gunpowder charge. The Carron Company was already selling a "new light-constructed" gun, two-thirds of the weight of the standard naval gun and charged with one-sixth of the weight of the ball in powder before it introduced the carronade, which further halved the gunpowder charge. The theory of its design was to use less powder and had other advantages that were advertised in the company's sales pamphlet of the time, state. The smaller gunpowder charge reduced the barrel heating in action, also reduced the recoil. The mounting, attached to the side of the ship on a pivot, took the recoil on a slider, without altering the alignment of the gun. The pamphlet advocated the use of woolen cartridges, which eliminated the need for wadding and worming, although they were more expensive. Carronades also simplified gunnery for comparatively untrained merchant seamen in both aiming and reloading that was part of the rationale for adopting the gun. Other advantages promoted by the company were. The replacement of trunnions by a bolt underneath, to connect the gun to the mounting, reduced the width of the carriage that enhanced the wide angle of fire. A merchant ship would almost always be running away from an enemy, so a wide-angle of fire was much more important than on a warship. A carronade weighed a quarter as much as a standard cannon and used a quarter to a third of the gunpowder charge. This reduced charge allowed Carronades to have a shorter length and much lighter weight than long guns. Increasing the size of the bore and ball reduces the required length of the barrel. The force acting on the ball is proportional to the square of the diameter, while the mass of the ball rises by the cube, so acceleration is slower; thus, the barrel can be shorter and therefore lighter. Long guns were also much heavier than Carronades because they were over-specified to be capable of being double-shotted,(to load cannons with twice the shot, for increased damage at the expense of range). Whereas it was dangerous to do this in a carronade. A ship could carry more carronades, or carronades of a larger caliber, than long guns, and carronades could be mounted on the upper decks, where heavy long guns could cause the ship to be top-heavy and unstable. Carronades also required a smaller gun crew, which was very important for merchant ships, and they were faster to reload. Additional notes: Cannon cast in England, Wales and Scotland had their imperial weight chiselled or engraved in the format of 4-2-0 on the bottom of the cascabel, indicating the weight of the cannon as 4 hundredweight, 2 quarters and 0 pounds. Since a hundredweight equals 112 pounds and a quarter weight is 28 pounds the total weight is 504 pounds or about 228 kilograms. The small bore replica carronade and carriage is part of a collection of nineteenth Century Flagstaff Hill Guns and cannons, and is a representation of carronades used from the early 18th up to the 1850s on merchant and military ships particularly the British Royal Navy until 1850. This example is not significant in the historic sense but demonstrates the type of artillery used aboard vessels of the time for protection & offensive military actions. Cannon, cast iron, small smooth bore cannon on the stepped wooden carriage with wooden wheels. It appears to fire a 12-pound cannonball. The Cannon barrel can have its elevation adjusted via a sliding sloped block at the rear of the cannon. Gun carriage has loops for locating and holding the carriage in position with the use of ropes. It is believed this carronade is a replica of a mid-to-late 19th-century Carronade cannon.Cast into metal; [Royal emblem of Queen Victoria (VR "Victoria Regina")]warrnambool, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, cannon, naval cannon, cannon on carriage, 19th century cannon, fortifications, smooth bore cannon, 12 pounder, carronade, artillery, replica, deck cannon, cannon in carriage, ship cannon
