A historical account including extensive stay in southern Arizona (Tucson, Tubac, Santa Rita Mountains, Sonoita, and other areas) from the early 1860s. This is one of the most depopulated and dangerous times generally in southern Arizona. Apaches fought back against intruders extensively in this period, to such a point many people of European ancestry left entirely; many settlements were abandoned by Mexicans and Americans both. Even the fort at Tucson was close to abandonment at this time, especially with uncertainties and battles of the Civil War.
The author does a decent job of describing some of the terrain of the region at a time when there were few previous written descriptions.
