On Melville’s "A Utilitarian View of the Monitor’s Fight"

Is the perspective in Herman Melville's Civil War poem about the USS Monitor's naval battle with the CSS Virginia -- the Battle of Hampton Roads -- “utilitarian”?

That is the question I want to pose in a few brief reflections on "A Utilitarian View of the Monitor’s Fight," that appeared in his Battle-Pieces and Aspects of the War, published in 1866. I am curious why Melville chooses that word for his title.
