Nine Years Among the Indians is an autobiography of Herman Lehmann, who was an eleven-year-old boy when he was captured by a raiding party of eight to ten Apaches alongside his older brother Willie. The Apaches called Lehmann "En Da" (White Boy). He spent about six years with them and became assimilated into their culture, rising to the position of petty chief. As a young warrior, one of his most memorable battles was a running fight with the Texas Rangers on August 24, 1875, which took place near Fort Concho, about 65 miles west of the site of San Angelo, Texas.The phenomenon of a white child raised by Indians made Herman Lehmann a notable figure in the United States.
