Columbiad

50-pounder Model 1811 Columbiad and center pivot mounting designed by George Bomford as an experimental coastal defense gun. This gun was built in 1811, and was one of the first weapons that were later referred to as Columbiads.[3][4] Photographed in Clear Lake, Wisconsin.

A Confederate 10-inch (254 mm) columbiad on a center pivot mount, as in Battery Four at Port Hudson, Louisiana. This gun could fire in any direction, and was so effective that Union troops referred to it as the “Demoralizer”.

The Columbiad was a large-caliber, smoothbore, muzzle-loading cannon able to fire heavy projectiles at both high and low trajectories. This feature enabled the columbiad to fire solid shot or shell to long ranges, making it an excellent seacoast defense weapon for its day. Invented by Colonel George Bomford, United States Army, in 1811, columbiads were used by the United States coastal artillery from the War of 1812 until the early years of the 20th Century. Very few columbiads were used outside of the U.S. and Confederate Armies; nevertheless, the columbiad is considered by some as the inspiration for the later shell-only cannons developed by Frenchman Henri-Joseph Paixhans some 30 years later.
