The lyrics (with notes) of "The Battle Hymn of the Republic,
Updated" (MT 1901), "a parody of American imperialism [Where
have we heard that of late???], in the wake of the
Philippine-American War," conveniently appears on
<wikipedia.org>. Which please see.

The words are also appended to an "op-ed" piece re "Thou shalt
not kill" which, again conveniently, appears online at
<http://www.sacred-texts.com/aor/twain/notkill.htm>. Which also
see. . . .

An interesting summary "encyclopedia article" re "The Battle
Hymn of the Republic" is -- conveniently -- online at
<wikipedia.org> including an excellent  facsimile of BH's first
appearance in _The Atlantic Monthly_ 9/52 (Feb 1862): 10; a
transcription of the original lyrics (including the oft-omitted
6th stanza); a list of interesting trivia re same; AND a note
regarding MT's parody. . . .

But my favorite BH site is at <cyberhymnal.org> which features
the original lyrics, a brief note regarding the hymn-poet's
composition, AND a photo of Julia -- she of the remarkably
etched countenance and piercing eyes. . . .

The religious content of BH? Old Testament / Hebrew Bible
imagery of course, especially for example Jeremiah 25:30.

I was sometime ago looking again at MT's anti-imperialism parody
-- for obvious? reasons  -- and hope you will let us know what
you may discover in the halls of the MT literati. . . .
