Williams gun

The Williams gun was a Confederate gun that was classified as a 1-lb cannon. It was designed by Captain D.R. Williams, of Covington, Kentucky, who later served as an artillery captain with a battery of his design. It was a breech-loading, rapid-fire cannon that was operated by a hand-crank. The barrel was four feet long and a 1.57-inch caliber. The hand crank opened the sliding breech which allowed the crew to load a round and cap the primer. As the crank was continued, it closed the breech and automatically released the hammer. The effective range was 800 yards but the maximum range was 2000 yards.
