Soon after the Gadsden Purchase was ratified in April 1854, Americans began settling in the Santa Cruz and Sonoita Creek valleys of southern Arizona. Popular Western travel writer John Ross Browne wrote that by 1861 the Santa Cruz Valley was well populated between Tucson and the Calabasas ranch, fifteen miles south of Tubac. But when he visited the area just three years later, Browne found that the ranches and mine sites of the area were deserted and in ruins. The immediate cause of this sudden reversal was raiding by Western and Chiricahua Apaches. But early relations between Apaches and Americans in the Southwest had been non-violent. So how did American settlement in the region come to be wiped out by Apache raids?
