Civil War in the Southwest - 2

While Sibley moved north into New Mexico, a company-sized cavalry detachment under Maj. Sherod Hunter was left with the difficult task of garrisoning Confederate Arizona, protecting the inhabitants from Apache raids, and with keeping the western road to Tucson open (apparently there were some filibustering pretensions directed at the Mexican state of Sonora as well). I haven't had the opportunity to read it, but author Boyd L. Finch has written a book on the subject titled Confederate Pathway to the Pacific: Major Sherod Hunter and Arizona Territory, CSA.
