Maybe of some interest to some of the chantey buffs out there...

I came across a recent (2008) article in the journal Archives of Natural History, vol. 35(2), drawing attention to a text, predating Nordhoff, that gives lyrics to "Fire Marengo." (Not to sound discourteous, but IMHO the analysis by the author, Williams, who doesn't seem to have much of a background in chanteys, doesnt offer much. Its chief value is in drawing attention to the text.)

Anyway, the text is "Letters from Alabama" by the naturalist Philip Henry Gosse. The "letters" were written during an 1838 visit to Alabama, during which he observed cotton screwmen at work on the Alabama river. The letters were first published in a periodical in 1855, then published in book form in 1859 -- you can find it as a free PDF download on Google.

Gosse renders the chorus of the chantey as "Fire the ringo.":

I think I heard the black cock say,
*Fire the ringo, fire away!
They shot so hard, I could not stay;
*Fire the ringo, fire away!
So I spread my wings and flew away
*
I took my flight and ran away
*
All the way to Canaday
*
To Canaday, to Canaday
Ringo! ringo! blaze away!
*

AND:
Gin'ral Jackson gain'd the day
*
At New Orleans he won the day

I had thought from Nordhoff that this "Fire Marengo" smacked of one of the "Stormalong" themed chanteys. Now, with these added lyrics, its not hard to imagine setting it to the "General Taylor"/"Walk Him Along, John" form of Stormy.
