Cochise/Mangas/Mexicans

Today I wrote an account that touches on Cochise's relationships with Mexicans. Historically they were enemies but practically the Apaches needed them for trade, commerce, especially horses/guns and population as they often captured young Mexicans and brought them back to camps to raise them as Apache. This relationship with Mexican states of Sonora and Chihuahua became even more critical after Apacheria passed to United States in 1853 with Gadsden Purchase. What triggers the matter is that Cochise joins Mangas to avenge death of his two sons in1858.
