The most popular cannon during the war, with over 1,500 guns having been produced. 131 Napoleons were used by the Union, and an estimated 30 were used by the Confederates during the Maryland Campaign. It was the most common artillery piece used by both sides during Antietam, with 117 of the total 131 being used during the battle by Union batteries, and 14 of 30 being used by Confederate batteries. This variation was produced by Confederate armories, and was distinguished by the lack of a flared muzzle.
