Book excerpt: Civil War and Revolution on the Rio Grande Frontier contains more than 125 of the best images taken by De Planque and other photographers, the vast majority having never been published. From numerous archives and private collections, these images include everything from the destruction following the killer hurricane of 1867 to gripping views of the heart-wrenching hanging of an American army deserter and three unfortunate followers of Cortina, who happened to get caught on the wrong side of the river.
