The Naval War of 1812. Theodore Roosevelt

      The smallest line-of-battle ship, the 74, with only long 18's on the second deck, was armed as follows:

      28 long 32's,

       28 " 18's,

       6 " 12's.

       14 short 32's

       7 " 18's

      or a broadside of 1,032 lbs., 736 from long guns, 296 from carronades; while the Constitution threw (in reality) 684 lbs., 356 from long guns, and 328 from her carronades, and the United States 102 lbs. more from her carronades. Remembering the difference between long guns and carronades, and considering sixteen of the 74's long 18's as being replaced by 42-pound carronades 50 (so as to get the metal on the ships distributed in similar proportions between the two styles of cannon), we get as the 74's broadside 592 lbs from long guns, and 632 from carronades. The United States threw nominally 360 and 486, and the Constitution nominally 360 and 352; so the 74 was superior even to the former nominally about as three is to two; while the Constitution, if "a line-of-battle ship," was disguised to such a degree that she was in reality of but little more than one half the force of one of the smallest true liners England possessed!
