Canon obusier de 12

The Canon obusier de 12 (French:"Canon obusier de campagne de 12 cm, modèle 1853", USA: 12-pounder Napoleon), also known as the "Canon de l’Empereur" was a type of canon-obusier (literally "gun-howitzer") developed by France in 1853. Its performance and versatility (it was able to fire either ball, shell, canister or grapeshot) allowed it to replace all the previous field guns, especially the Canon de 8 and the Canon de 12 as well as the two howitzers of the Valée system.

The cannon owes its alias to French president and emperor Napoleon III.
