The Civil War Era represents a period when radical advances in cannon technology increased power, range, and accuracy. Brigadier General Thomas Rodman's process for hollow casting cannon allowed for larger cannon and bigger powder charges. Mr. Robert P. Parrott's rifled cannon, among others, provided greater range and accuracy. With few foundaries, the Confederacy was forced to use existing weapons, often "rifling and banding" older smoothbore cannon to increase firepower and range. The cannon in front of you represent some of the best examples of cannon produced and modified using these processes.
Banding a cannon increased its firepower. A band of wrought iron, expanded by heat, was slipped over the cast iron barrel. The band cooled, shrinking tightly in place, strengthening the breech to withstand the pressure of a greater
Rifling (cutting spiral grooves in a weapon's bore) gave a stabilizing spin to a projectile. Rifled cannon had greater range than smoothbores of similar size, and their new projectiles were usually more accurate and destructive than the old, round shot and shell.
