12-Pounder Napoleon-Confederate Manufacture

12-pdr. Napoleon (CSA)
The 12-pounder field gun was developed in France in the 1850s and was named for Emperor Napoleon III. At Gettysburg, it made up 39% (107/272) of the total Confederate field pieces. The C.S.A. version of the 12-pdr. is distinguished from the U.S.A version by the lack of a muzzle swell, the tube being straight. The Napoleon fired solid shot, shell, spherical case, and canister. In overall effectiveness it had no peer.
