Twelve-pound cannon

The twelve-pound cannon is a cannon that fires twelve-pound projectiles from its barrel, as well as grapeshot, chainshot, shrapnel shells and canister shot. [http://www.civilwarartillery.com/] It was first used during the Tudor period [http://www.contentparadise.com/us/user/british_naval_12lb_cannon_for_3d_studio_max_product_32286] and reached its production top in the Napoleonic wars (1812-1815). It was a favorite weapon of the Grande Armee; these muzzle-loading smoothbore 12-pounders were later known as Napoleon cannons in honor of the French emperor, himself a former artillery officer.
In addition 12-pounders were carried on the quarterdeck of British Ships of the line like HMS Victory though their main weapons were the larger 24 and 32 pound cannon, capable of shattering the hulls of enemy warships and killing the gun crews with a deadly shower of splinters.

Napoleon cannon remained in service during the Victorian period, [http://www.galenahistorymuseum.org/napoleon.htm] seeing action in the American Civil War.

These weighed between 10 and 300 pounds [http://www.cwartillery.org/ws-reg.html] though the Napoleons remained the most common field guns in Confederate hands.
