Time Travel Is All I've got Left

[busker]

It’s not World War II
more like the Plains Indian wars
fought in a wilderness of prairie and river, 
mountains and hidden streams, ….. these 2 lines don’t add much to the poem 
murdered settlers, burned out villages, …. I like the contrast 
buffalo and elk, eagles overhead. …. Vultures would perhaps be too cliche, but “eagles” makes it a list. A single eagle (why single?)? Something interesting?

My romantic view of a life … I’m missing the irony here. Is the long sentence here ending correctly?
at the end of its century
where I wander, not quite an outcast,
but homeless 
at bay in an endless grassland.
I’ve lost my gun and my horse,
no one but me and my old dog.
Where do I go from here?

I like the idea of how even time travel doesn’t get you the happiness you’re after
