The Model 1857 12-Pounder Napoleon Field Gun, officially called the light 12-pounder gun by the United States Army, was the most popular smoothbore cannon used during the American Civil War. The cannon was named after French president and emperor, Napoleon III, nephew of Napoleon Bonaparte.

It was of a cast bronze smoothbore design. It was light enough to be pulled by a team of horses. The U.S. version of the Napoleon could hit a target up to 1,700 yards (1,600 m) away. However they were most accurate at closer ranges of about 250 yards (230 m). It used a charge of 2.5 pounds (1.1 kg) of black powder. The M1857 Napoleon fired a cannonball or canister shot at a speed of 1,440 feet per second (or 439 meters per second). The barrel had a bore of 4.62 inches (117 mm) in diameter and was 62 inches (1,600 mm) long. The barrel alone weighed 1,220 pounds (550 kg). With its gun carriage it weighed 2,445 pounds (1,109 kg) and was pulled by a team of six horses. The average gun crew was six men. (Source: Wikipedia)
