6-pounder Gun
The 6-pounder was the prime artillery piece of the Mexican War and the smallest regulation gun of the Civil War. The Confederacy and the Union armies in the west used it extensively, but it was replaced in the Union armies in the east by the Napoleon and the rifled gun. Its normal range was 1500 yards. It fired fixed ammunition - either solid shot, spherical case, or canister.
