The 8-Inch Columbiads, Pattern 1844, of Medina, New York
Two US Army 8-Inch Columbiads, Pattern 1844, guard the veterans section of and flank the gates to a cemetery in Medina, New York.

The 8-Inch Columbiad, Pattern 1844, of Fort Sumter
The US Army 8-Inch Columbiad, Pattern 1844, looks almost insignificant at Fort Sumter as it rests between two gargantuan 50,000 pound 15-Inch Rodmans which were brought to the fort in the 1870s. The smaller Columbiad is missing a portion of its muzzle, its right trunnion, and much of its cascabel. It's not mounted on a carriage like the cannons in the casemates. An interpretive sign notes that several of the type were present at the fort in 1861 and that this cannon probably has remained there since then.
