found a bit more of the poem, but oddly, not the whole thing

"Farewell to my country, I fought for thee well.
When the savage rushed forth like the demons from hell.
In peace or in war I have stood by their side.
My country for thee I have lived--and would have died.
But I am cast off, my career now is run
And I wander abroad like the prodigal son,
Where the wild savage roves, and the broad prairies spread,
The fallen--despised--will again "go ahead."
