Collected by Herbert Halpert from Blanding Sloan in New York City, July, 1938:

"Sahnty Ahnna lost his leg,
Along the plains of Mexico!
Hurrah, Sahnty Ahnna!

"Sahnty Ahnna's dead and gone,
Along the plains of Mexico!
Hurrah, Sahnty Ahnna!

"My father sang that song. He was a drummer boy in the Mexican War, and that was sung by the American troops."

Sloan's tune is similar to those used today, but not so good.

We can't know whether his father actually heard it in the Mexican War of 1846-48 or picked it up later. Santa Anna lived till 1876.
