Sullivans Island in Charleston County, South Carolina — The American South (South Atlantic)
Civil War Armament
1861 - 1865
Union armories produced new, larger rifled cannon; the South had few foundries and used existing weapons, often "rifling and banding" older smoothbore cannon to increase firepower. Confederates used a wide variety of weapons at Fort Moultrie. If you look into the cannon barrels here you can see some smoothbores and some that are rifled.
Banding 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 powder charge. For more strength, additional bands were added.
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 shells.
The new elongated shells had an aerodynamic shape, and were larger, heavier, and could be filled with explosives.
To fire mortars and cannon, the hook of the lanyard was attached to the friction primer. When the lanyard cord was pulled, the primer's flame ignited the powder
The short-barreled mortar fired spherical shells with timed fuses. Mortars were designated to fire upward in an arc, while cannon fired in a low trajectory.
