The 3-inch Wrought Iron Rifle, sometimes called the 3-inch Ordnance Rifle, Griffen Gun, 10 pdr. Ordnance Rifle and incorrectly referred to as a Rodman Gun, is a muzzle loaded field artillery piece used extensively during the American Civil War. Invented by John Griffen, it was extremely durable, with the barrel made of wrought iron, primarily produced by the Phoenix Iron Company of Phoenixville, Pennsylvania. The rifle had exceptional accuracy. During the Battle of Atlanta, a Confederate gunner was quoted: "The Yankee three-inch rifle was a dead shot at any distance under a mile. They could hit the end of a flour barrel more often than miss, unless the gunner got rattled". For this reason, 3-inch rifles were highly sought after during the war.
