Dahlgren guns were muzzle-loading naval gun designed by a United States Navy Rear Admiral John A. Dahlgren (November 13, 1809 – July 12, 1870), mostly used in the American Civil War. Dahlgren's design philosophy evolved from an accidental explosion in 1849 of a 32 lb (14.5 kg) gun being tested for accuracy, killing a gunner.

12-pounder gun or 12-pdr, usually denotes a gun which fired a projectile of approximately 12 pounds. Guns of this type include: 12-pounder long gun, the naval muzzle-loader of the Age of Sail; Canon de 12 de Vallière, French cannon of 1732; Canon de 12 Gribeauval, French field cannon of the mid-late 18th century
The 12-pounder long gun was an intermediary calibre piece of artillery mounted on warships of the Age of Sail. They were used as main guns on the most typical frigates of the early 18th century, on the second deck of fourth-rate ships of the line, and on the upper decks or castles of 80-gun and 120-gun ships of the line.
John Adolphus Bernard Dahlgren (November 13, 1809 – July 12, 1870) was a United States Navy officer who founded his service's Ordnance Department and launched significant advances in gunnery. Dahlgren devised a smoothbore howitzer, adaptable for many sizes of craft and shore installations.
The Dahlgren site was named the Lower Station, Dahlgren Naval Proving Ground when it first opened. The location on the Potomac River was specifically chosen for the development of a long ballistic test range on the Potomac River, required for the testing of modern, high-powered munitions. [2]

By far the most popular of the smoothbore cannon was the 12-pounder model of 1857, Light, commonly called "Napoleon". The Model 1857 was of lighter weight than the previous 12-pounder guns, and could be pulled by a six-horse draft, yet offered the heavier projectile payload of the larger bore.
