Book excerpt: Life in early New Mexico was often perilous. Geographic isolation attracted outlaws and ruffians, and skirmishes often arose between the indigenous tribes and settlers. In response, the U.S. government set up military forts and outposts to protect its new citizens. These strongholds include Fort Craig, where logs were made to look like cannons to fool Confederate troops. Kit Carson, John Pershing and Billy the Kid all called Fort Stanton home, before it became the first federal tuberculosis sanatorium and later a detention center for German prisoners of war. Author Donna Blake Birchell relates little-known yet highly important Civil War battles, the tragedies of the Navajo and Mescalero Apache internments and other dramatic frontier stories.
