  Columbiad \Co*lum"bi*ad\, n. [From Columbia the United States.]
     (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.
     [1913 Webster]


  
     Note: 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}.
           [1913 Webster]
