This work, by a non-Mormon historian of Arizona, discusses the titular topic and was produced some time ago by Project Gutenberg Distributed Proofreaders. (As longtime readers know, I think very highly of PGDP.) It touches on the Mormon Battalion, pioneer and Forty Years Among the Indians author Daniel W. Jones, noted missionary Jacob Hamblin, and the ancient history of the area, among other things. Give it a look.
The existence of this e-book somehow escaped our notice up until now, but no longer; now it’s on the Available Texts page. On that note, should anyone know of similar works already available on PG or elsewhere, get in touch–we want to get the word out about them.
