    • n Columbiad (Mil) A form of seacoast cannon; a long, chambered gun designed for throwing shot or shells with heavy charges of powder, at high angles of elevation.☞ Since the War of 1812 the Columbiad has been much modified, especially by General Rodman, and the improved form now used in seacoast defense is often called the Rodman gun.

    • n columbiad A heavy castiron smooth-bore cannon of a form introduced by Colonel George Bomford, U. S. A., and used in the war of 1812. Columbiads were made of 8-and 10-inch caliber, and were used for projecting both solid shot and shells. They were equally suited to the defense of narrow channels and distant roadsteads. In 1860 General Rodman, of the United States ordnance, devised a 15-inch columbiad, which was cast hollow, and cooled from the interior, thus increasing the hardness and density of the metal next the bore. These guns are now obsolete.
    • n columbiad [capitalized] An epic of Columbia, that is, America: used as the title of several poems, as one by J. L. Moore (1798), one, better known, by Joel Barlow (1808), and one in French (La Colombiade) by Madame de Boccage (1756).
