I think this is a reference from 1858 to "Hilo, Boys, Hilo". It is found in A CUBAN EXPEDITION, by J.H. Bloomfield, published in 1896.

The reference to the "execution of Colonel Crittenden in Havana", found on page 1 of Bloomfield's "Introduction" is documented here:

Bloomfield says that his expedition set sail for Cuba seven years after this event, which would be 1858. A rather complete song is given by Bloomfield.
