The M1841 12-pounder field howitzer was a bronze smoothbore muzzle-loading artillery piece that was adopted by the United States Army in 1841 and employed during the Mexican–American War and the American Civil War. It fired a 8.9 lb (4.0 kg) shell up to a distance of 1,072 yd (980 m) at 5° elevation. It could also fire canister shot and spherical case shot. The howitzer proved effective when employed by light artillery units during the Mexican–American War. The howitzer was used throughout the American Civil War, but it was outclassed by the 12-pounder Napoleon which combined the functions of both field gun and howitzer. In the U.S. Army, the 12-pounder howitzers were replaced as soon as more modern weapons became available. Though none were manufactured after 1862, the weapon was not officially discarded by the U.S. Army until 1868. The Confederate States of America also manufactured and employed the howitzer during the American Civil War.
